Title: Application of Conventional and Mutation Approaches in Genetic Improvement of Tuberose (Polianthes tuberosa L.): A Review on Recent Development and Future Perspectives
Abstract :
In recent days, improved conventional techniques, including division of the bulbs, removal of leaf and flower spikes, standard size of the bulb, and mechanical removal of sprouts, have been used to obtain improved quality planting materials in tuberose. Mutation breeding is also another technique that is used for improvement in tuberose. In mutation breeding, novelty can be created in an already well-established cultivar. Any change in the genes and their expression can be easily measured in the first generation of mutants by selecting desirable characters like flower color, shape, size, fragrance, etc. In the present review, the works carried out on tuberose by various workers worldwide from the last 40 years have witnessed conventional and mutation approaches made in the genetic improvement of tuberose. This review also highlights the role of selection for the identification of desirable traits, self-compatibility, and hybridization approaches made in tuberose species worldwide by several research institutions. Factors that affected mutation efficiency have also been presented and discussed from available data. Overall, the present reviews provide a consolidated account for the application of traditional and mutations approaches and suggest how their implications can be useful for genetic improvement of tuberose.
Title: Instability and Decomposition Analysis of Sesamum Crop Production in Karnataka and India
Abstract :
Sesamum is one of the oldest oilseed crops generally grown in Africa and Asia for its high-quality nutritional value. The instability in sesamum production was examined by employing instability index. At all India level, the instability in sesamum area and production has increased from Period I to Period II and it declined in Period III. Interestingly the instability in productivity of sesamum has marginally declined from Period I to Period II and from Period II to Period III. In the case of Karnataka state, in area and production instability of sesamum has increased from Period I to Period II and to Period III. Further, the study conducted a decomposition analysis to determine the contribution of different components to the sesamum production. The results of the decomposition of change in average sesamum production in India as well as in Karnataka shows, change in mean area and interaction between mean area and mean yield influencing change in average production of sesamum in overall period. Among the ten constituents of change in variance of production of sesamum, change in area variance is the dominant reason for instability in sesamum production. In Karnataka, change in area variance contributed maximum to change in variance of production in all the four periods, followed by interaction between changes in mean yield and area variance. The study findings suggest the need for research efforts to concentrate on production techniques, improve productivity, and developing varieties with higher productivity potential, wider adaptability, application of improved crop protection techniques, and capacity building for expertise in agronomic practices will have a vital role in providing modern system of sesame production in India.

Title: Oil Content and Fatty Acid Composition in Castor (Ricinus communis L.) Genotypes
Abstract :
Castor (Ricinus communis L.) is an important non-edible oilseed crop with diversified industrial usage. In the present study, twenty-six genotypes of castor were analyzed for total seed oil content using Nuclear Magnetic Resonance (NMR) spectroscopy and fatty acid profiling through gas chromatography with flame-ionization detector (GC-FID) to update the database of this important industrial crop. In the present study, the highest seed oil content was determined in SHB-1019 genotype which was 45.86 %.
Total saturated fatty acid, steric acid and palmitic acid per cent was recorded higher in SKI-370 genotype which was 3.38 %, 1.92 % and 1.46 %, respectively. Among the all genotypes, the higher per cent of total unsaturated fatty acid, ricinoleic acid and linolenic acid was observed higher in genotype VI-9 whereas, mono unsaturated fatty acid (oleic acid) and poly unsaturated fatty acid (linoleic) was found higher in genotype GEETA. The present study can be very important in the selection of male parents for the development of high ricinoleic acid castor hybrid. This will ultimately help in increasing the production and quality of industrially important oil.
Title: Clonal Propagation of Thespesia populnea (L.) Soland ex Correa
Abstract :
Clonal propagation was attempted in Thespesia populnea. Among the four rooting media used, namely pallam sand, potting mixture, vermiculite, and composted coir pith, pallam sand was the most effective one. Among the four different hormone treatment combinations (1000, 2000,3000, and 4000 mg l-1 of IBA), IBA at 3000 mg l-1 was promising for this species. Composted coir pith failed to produce any response. Under in vitro conditions, direct shoot and root formation were noticed in MS medium or Woody Plant Medium containing BAP (1.0 mg l-1) and IAA (0.1 mg l-1).

Abstract :
The present study attempts to identify the Economic analysis of vegetable production in Arnia block of Jammu district of Jammu and Kashmir Union Territory. The study was conducted in Arnia blocks of Jammu district. Data for the study was collected from a sample of 24 vegetable growers. Farmers in the Arnia block grew three major crops: cabbage, cauliflower, and tomatoes. The findings revealed that, of all the inputs used, the spending on human labour was the greatest. The results regarding cost structure of vegetable cultivation in Arnia block witnessed the largest cost which is incurred in tomato growing and the lowest cost was incurred in cabbage cultivation. The total cost of cultivations in the Arnia block was highest in tomato and lowest in cauliflower. The tomato yielded the highest gross return, while cabbage yielded the lowest. The total gross income from all of the veggies was ` 121416.66 per hectare. The highest net returns per hectare was observed in tomatoes, while the lowest was observed in cabbage. The cost-benefit ratio was highest for tomato and lowest for cabbage. In Arnia block farmers follows channel- I to sell their produce in the market such as tomato, cabbage, and cauliflower. The container expense ate up the majority of the marketing cost. Aside from that, transportation expenditures made up a considerable portion of the producer’s marketing costs. Retailer’s received highest margins in tomatoes, while cauliflower received the lowest at retailer level. Tomatoes have the highest producer share in consumer rupee, whereas cauliflower has the lowest. The total marketing margin was highest in cauliflower, while it was observed lowest tomato. Transportation costs accounted up the majority of marketing costs at the producer and retailer levels.
Title: Economic Analysis of Basmati under Organic and Non-Organic Conditions
Abstract :
Jammu and Kashmir Union Territory is divided into varied agro climatic zones temperate Kashmir valley and humid sub-tropical and tropical region of Jammu. Each has its own specific geo-climatic conditions which determine the cropping pattern and productivity profits. Organic farming has been considered as one of the best options for protecting/sustaining soil health, and is gaining lot of importance in present day agriculture. The present study was confined to the Research Farm, SKUAST, Jammu, Chatha, Jammu and Kashmir Union Territory as this farm has the area under both organic and non-organic basmati. The per hectare cost of cultivation of organic and non-organic basmati rice for human labour, machine labour and irrigation charges were found to be same i.e., ` 6863.12, ` 3587.05 and ` 3640.00 respectively. Whereas expenditure incurred on other items such as seed and manure and fertilizer were found to be maximum in organic cultivation i.e., ` 1800.00/ha and ` 12000.00/ha respectively. The per hectare cost C2 was ` 30201.13 for organic farm, and ` 19790.49 for non-organic farm. After working out management cost, i.e., 10 percent of cost C2, per hectare cost C3 found to be ` 33221.24 and ` 21769.53 for organic and non-organic farms respectively. Cost benefit ratio for non-organic basmati is higher as compare to organic basmati whereas the net return per hectare in organic basmati is higher as compare to non-organic basmati.
Title: Issues in Adoption of Drip and Conventional Irrigation Methods in Banana: A Socio-Economic Analysis of South Gujarat Region
Abstract :
Irrigation water management is a key input as well as a major constraint for assured and successful crop production. The adoption of drip irrigation method among the farmers of South Gujarat in water loving crops like banana is a wise tool for conservation of resources. However, this method has its own limitations which were ranked using the Garrett ranking technique. The study revealed that high initial capital investment, clogging of emitters due to water salinity and frequent damage of the system due to rodents, pigs and other animals were identified as the top three major problems faced by the farmers with a Garrett score of 81.59, 74.15 and 68.19, respectively. The farmers practicing conventional method of irrigation were of the opinion that wastage of water in the form of excess irrigation was the most acute problem and was ranked first with a Garrett score of 80.21, followed by high electricity usage (73.68) and problem of water logging (67.03). Hence, based on the ranking of these major constraints in adoption of drip irrigation technology; the study suggested ways and means to address these issues which would in turn help to reduce the considerable gap in the estimated achieved and achievable water savings.

Title: Quality of Rose Flowers in Different Types of Cultivation
Abstract :
Floriculture is an essential branch of Horticulture concerned about growing and cultivating the flowers, foliage plants, and their marketing. It also deals with the production of planting materials through seedling, cutting, budding, and grafting. Polyhouse is a technology for flowers and vegetable cultivation through which farmers can get high and quality production and benefits. So, a study was planned for finding the quality of rose flowers in open cultivation and different polyhouses. The research was carried out in two different types of polyhouses and an open area. It was found that all the environment parameters, i.e., light, temperature, humidity, and CO2, were significantly higher in NVPH type of polyhouse compared to AISNH and open cultivation. Except for the diameter of rose flowers, all the other parameters of quality of flowers i.e., color, the height of flowers, a diameter of flowers and spikes etc., were higher in NVPH and AISNH than in the open cultivation.
Title: Plant Growth Regulators and their Implication in Ornamental Horticulture: An Overview
Abstract :
Now a day, plant growth regulators have been used by the nurserymen and commercial growers of ornamental plants as a part of cultural practices. PGRs have quicker effect on ornamental plants including foliage and ornamental grassess to modify growth, foliage colour as well as flower yield. Application of growth regulators have various advantages on ornamental plants like less time consuming to treat the plant and its use are environment friendly. Various factors contributing to the efficacy of plant growth regulators among them the method of application plays a key role in determining the efficacy of plant growth regulators. PGRs and new class plant growth regulators can be very effective on flowering and foliage plants, if properly applied at appropriate concentrations and time. Implication of PGRs in flowering and foliage plants must be specific their action and ensure that it should be nontoxic and environmentally safe. It has been observed from various research reports that the physiological activities of flowering and foliage plants are regulated by the growth regulators and finally affects the growth of plants as well as flower production of various flowering plants. Plant growth regulators also play a significant role in propagation by means vegetative, seed treatment, in vitro propagation and in vitro rooting of ornamental and foliage plants. Besides these, PGRs are also involved in prolonging the life of flowers, vase life of cut flowers, plant growth promotion and regulation of flowering, breaking of dormancy in seeds, bulbs, corms and tubers of flowering plants, enhancing apical dominance, lateral branching, plant height control and delayed flowering. In the present overview, we discuss the types of plant growth regulators their applications and effect on flowering, foliage including ornamental grasses.
Title: The Northeast India in the Midst of Climate Change
Abstract :
With increased temperatures, melting glaciers, decreasing water supplies- the threat of climate change is becoming very real. The IPCC report on climate change has warned that these effects will only worsen, especially for developing and tropical countries, if action is not taken now. The Northeast region of India is highly vulnerable because of its location, its transboundary river basins, and socio-economic instabilities. The threat of climate change has only heightened these vulnerabilities through flood, drought, heatwaves,
soil erosion, loss of livelihood, and migration. Thus, challenging the very sustainability and security of the region. Every year, the northeast region is increasingly seeing fewer rainfalls, leading to a droughtlike situation in the states of Meghalaya, Tripura, Assam, Arunachal Pradesh Manipr, Mizoram. With the farmers relying on the monsoon, this lessening of waters adversely affects agriculture; for instance, rice production in Assam has fallen by 15-20%. The majority of people in Assam rely on agriculture for their livelihood. Because of climate change and the lessening of agricultural production, the food prices in Assam are pushed up. In Assam, 35% of the population lives below the poverty line. A rise in prices and loss of livelihood force the people to migrate in search of new opportunities and means of livelihood. Often women bear the brunt of this situation, with them having to take up labor as housemaids or, in a worse situation, pushed into flesh trade. The Intergovernmental Panel on Climate Change special report on ‘Climate Change and Land’ reports that about one third of the food that is produced is lost or wasted and by reducing this wastage we can reduce greenhouse gas emissions as well as improve food security. Thus, killing two birds with one stone.
Title: Effect of Potassium Nitrate Priming and Different Growing Media on Papaya Seed Germination
Abstract :
The study was conducted to investigate “Effect of potassium nitrate and different growing media on papaya seed germination”. For the study, the incorporated statistical design was Completely Randomized Design (CRD) with six different treatments consisting of 1% and 3% priming with potassium nitrate for 15-20 minutes and growth media comprised of compost, coco peat, and garden soil in three replications. In terms of germination and vigor significant difference was observed from 3rd week after emergence. From this study, it was obtained that the percentage of germination (90%), as well as the time taken for the seed to germinate first (6 days) was seen as excellent for T6 (3% KNO3 + 50% Coco peat + 25% Compost + 25% Garden soil). T1 (0% KNO3 + 60% Coco peat + 20% Compost + 20% Garden soil) was found to give the highest parameters in terms of length of leaves (2.35 Cm), number of leaves (5.5), root length (8 cm). The various growth parameters such as viz., number of roots (30.5), were observed highest in the T5 (1% KNO3 + 50% Coco peat + 25% Compost + 25% Garden soil). The seedling height (16.65 cm) was found to
be maximum in the T6 (3% KNO3 + 50% Coco peat + 25% Compost + 25% Garden soil). Therefore from this study done it may very well be said that T6 (3% KNO3 + 50% Coco peat + 25% Compost + 25% Garden soil) showed the best result concerning germination and different growing media had a significant influence on the growth and vigor parameters of papaya seedlings.
Title: Deciphering the Impact of Water-stress on Plant Growth and Yield Attributes in Tomato Genotypes
Abstract :
The adverse effect of water-stress on growth and yield parameters of tomato (Solanum lycopersicum) genotypes viz., plant height, days to 50% flowering, number of branches per plant, number of flower per truss, number of flower truss per plant and fruit setting percentage was investigated under field conditions in rainout shelter. The drought condition was imposed 25 days after transplanting by withhold water supply. Experimental trial was carried out with nine genotypes adopting complete randomized design (CRD) with three replications and two treatments viz., well-watered and withhold water supply. The water-stress caused reduction in all plant growth and yield parameters. The genotypes Arka Vikas showed significantly less reduction in plant height, number of flower per truss and number of flower truss per plant, while EC179083 showed minimum reduction in days to 50% flowering, number of branches per plant and fruit setting percentage during drought so both genotypes were considered as drought tolerant. Genotypes EC160885 and EC 249508 represented the maximum reduction in all morphological parameters among all genotypes, hence considered as drought susceptible.

Title: Impact Analysis of an Innovative Extraction Process for Ndjansang (Ricinodendron heudelotii) Seeds on the Welfare of Local Producers in Nyong and Mfoumou Division, Cameroon
Abstract :
Ndjansang is a non-timber forest product (NTFP) that is part of the traditional medicinal, cosmetic and gastronomic practices of populations in sub-Saharan Africa. Although its price has increased considerably in recent years, making it an essential source of income for farming households, its production level remains low due to the arduous extraction of almonds, making the production process laborious and burdensome. The introduction of innovation such as the almond crushing machine to ease hired conditions and improve the welfare of producers seems indispensable. Therefore, this article assesses the impact of the adoption of this innovation on producers’ income in Cameroon’s central region. The non-experimental method of assessing impact using propensity scores was used on a sample of 216 producers selected in a reasoned manner. The results reveal that producers who adopted the innovation in the production process experienced a considerable increase in their income per kilogram in Ndjansang (US$ 0.16 per kg) with a statistically positive and significant effect of 1%, compared to manual production. Seed quality has also been greatly improved, as some manually ground almonds have been broken or transported under dangerous conditions. This allows producers to spend more time on other income-generating activities. Variables such as membership of the farmer organization, quantities produced, household size, and the Ndjansang bowl price are the main determinants of the adoption of this innovation. Indeed, the farmer organization’s membership is an essential factor in adoption because the producer who is enrolled in a farmer organization can have access to more innovations, information, resources, and training. In order to ensure sustainable income and welfare for producers, it is then essential to introduce and disseminate this innovation through value-adding policies in the Ndjansang value chain.
