The first spray was applied soon after the bunch had completely opened, and the second spray was applied 15 days later. The effect of these chemicals on yield and quality parameters was observed. The result revealed that the application of GA3 @ 100 ppm increased the length, girth and weight of the bananas. Likewise, the highest weight of the third hand of the banana was also observed in GA3 @ 100 ppm, whereas minimum physiological loss in the weight of the finger and maximum pulp to peel ratio was observed in SOP @ 1.5%. Analyzing all these observed parameters, GA3 @ 100ppm was found to be the most suitable growth hormone to increase the overall yield while SOP @ 1.5%\u0000SAARC J.

The mutant MBM-07(S)-2 was found to be the tallest (32.57 cm) with highest number of branches/plant (5.03), highest number of leaves/plant (11.06) among all mutants and check variety while MBM-07-Y-2 (23.40 cm) was the shortest plant height, MBM-656-51-2 had the lowest number of branches/plant (3.73), MBM-347-13 (7.03) had the lowest number of leaves/plant. The mutant MBM-427-87-3 had the highest number of pods (5.00) compared to other mutants but MBM-656-51-2 had the lowest number of pods/plant (3.09).

Amylose content of rice endosperm is the main chemical properties that contributes the eating and cooking quality. On the other hand, rice protein is the important source of nutrition of almost 50 per cent of the world’s population living on rice. A total of 12 rice genotypes including ten advanced mutant lines, one landrace namely Laxmidigha along with BRRI dhan49 was collected from Plant Breeding Division of Bangladesh Institute of Nuclear Agriculture (BINA), Mymensingh and Bangladesh Rice Research Institute (BRRI), Gazipur. The genotypes were analyzed to assess the amylose and protein content as well as their genetic diversity relationship. Among all the tested genotypes amylose content were ranged from 23.9-20.3% where highest amylose percentage was found for Magic-86 (25.6%). Protein content of the genotypes were ranged from 8.50-5.04%, where highest 8.86% protein was recorded for SSB-3. The highest gene diversity (0.81) was observed in RM519 marker and the lowest (0.28) was in RM111 marker. The PIC values ranged from 0.24-0.78 with a mean of 0.51.

But the productivity of potato in the state is low as compared to other states. Among the various factors, productivity of a crop is significantly influenced by technical efficiency. This paper examines productivity and technical efficiency in potato cultivation in Brahmaputra Valley of Assam, India. The study is based on both secondary and primary data. Primary data were collected from a sample of 400 potato growers. The study applied stochastic frontier production function to estimate technical efficiency and employed logistic transformation model of regression analysis to examine the determinants of technical efficiency. The results showed that potato productivity was positively and significantly affected by seed, fertilizer and manure costs. The mean level of technical efficiency among the farmers was 78%. Technical efficiency was found to be the highest in semi-medium and large land holdings. Technical efficiency was positively affected by land size and negatively affected by capital-labour ratio. The study implies that there is a need to promote use of quality seeds and plant nutrients to improve productivity and encourage extensive farming and use of labour to enhance technical efficiency in potato cultivation.\u0000SAARC J.

A total of 100 vegetable growers were selected using a simple random sampling technique. Data collection was done by using a semi-structured interview. Secondary data was collected from the reports and journal articles. Indexing techniques and descriptive statistics were used in this study. It was estimated that the average size of a household's landholding was 0.1689-0.337 hectares. Forty-eight percent of the households earned NRs 1,00,001–2,00,001/year from vegetable farming. About 93% of the farmers were interested in off-season vegetable production. Around 45% of households used different fertilizers, namely urea, DAP, and MOP. Insect and disease attacks (index value = 0.82) were the major problems. Aphid (index value = 0.818) and blight (index value = 0.768) were reported as the major pest and disease, respectively. About 47% of farmers grew hybrid seeds. Farmers sold their products in India (50%), Dadeldhura (30%), and local markets (20%).The management of insect pests and diseases, access to chemical fertilizers and hybrid seeds, and the provision of offseason vegetable production training to farmers are necessary for the promotion of commercial vegetable production in the district.\u0000SAARC J.

Based on the functions any value chain includes three function actors and different dimensions such as inclusiveness (i.e., extreme poor inclusion) and gross margin, the study qualitatively and quantitatively assessed mango fruit value chain. Methodologies were applied with an assemblage of bottom-up and top-down approaches. Structured questionnaires were used to survey mango producing households, input sellers and mango buyers. The percentile value of composite revealed that mango fruit production and selling the annual specified gross margin (SGM) were Tk.1,600 (66%) for extreme poor (hereafter referred to as EP) producers, while Tk.1,09,880 (64%) for rich producers and Tk. 2,43,000 (76%) for retailers/middleman. The profit margin of medium and rich producers as well as middlemen was better, but less for poor and EP households due to the systemic market constraints. This assessment aims to prepare improving strategies and/or interventions for mango production that elucidates what actions could be taken for the mango fruit value chain in different segments such as improved technologies, harvesting, grading, packaging, transportation, marketing, etc. so that the poor and EP households will get more profit margin from mango production.\u0000SAARC J.

It was found that rice pest like Rice yellow stem borer, Rice leaf roller, Green leaf hopper, Brown plant hopper, Rice leaf miner, Rice gall midge, White leafhopper, Rice bug, Rice ear cutting caterpillar, White-backed planthopper, Rice caseworm, Grasshopper, Rice skipper and Rice beetle were the major insects that captured under the solar light traps.

Apis melifera is the major honey bee reared by the beekeepers and the average number of boxes is 50, harvested honey per box per year is around 35 kg. Profitability analysis shows that honey production was profitable and the benefit-cost ratio is 1.83. Estimates of logit model indicates that age of household head, educational level, farm size, farm income and non-farm income were the significant factors that influence beekeepers’ decision for adoption. The study identified six actors in honey value chain and among the actors; processors added the highest value of total value addition. Engagement in different activities of beekeeping had a great impact on their livelihood. SWOT analysis indicates favorable environment as strength, inadequate market infrastructure as weakness, high demand for honey as opportunities, and dominancy of the middlemen as threat, respectively. Lack of credit, lower price of honey as well as lack of storage facilities was the main problems faced by the stakeholders. To overcome the problems moreover to make this business more profitable, the study recommended to form contract based cooperative groups, establish proper storage facilities and provide necessary training by the government and non-government organizations.\u0000SAARC J.
