Influence of Organic Manures and Bio-fertilizers on Qualitative and Qualitative Traits of Cashew cv. BPP-8 in Odisha Condition

Abstract:

Being one of the major cash earning crop the productivity of cashew (Anacadium occidentale L.) in India as well as world is very low compare to other cashew growing countries. Low productivity of cashew is encompasses by the use of seedling planting materials, no irrigation facilities, nutrient management and other cultural practices. To address the low productivity and quality of cashew an attempt was made at AICRP on Cashew, Bhubaneswar, Odisha under OUAT by using different organic manures and bio-fertilizers in the cashew cultivar BPP-8 during the year 2018-19. The experiment was laid out in Randomized Block Design (RBD) with three replications and nine treatments including different organic sources along with control i.e. T1: 100% N as FYM, T2: 100% N as FYM + Bio-fertilizer consortia (200g/plant), T3: 50% N as FYM + Bio-fertilizer consortia (200g/plant), T4: 100% N as Vermicompost + Bio-fertilizer consortia (200g/plant), T5: Recycling of organic residue with the addition of 20% cow dung slurry, T6: In situ green manuring / green leaf manuring to meet 100% N, T7: 25% N as FYM + recycling of organic residue + in situ green manuring /green leaf manuring + Bio-fertilizer consortia (200g/plant), T8: Recommended doses of fertilizer + 10 kg FYM, T9: Farmers’ practice (Control). From this experiment it was observed that nutrient management of cashew in the form of organic source 25% N as FYM + recycling of organic residue + in situ green manuring/green leaf manuring + Bio-fertilizer consortia 200g/plant may give better results compare to others in terms of apple weight, nut weight, kernel weight, shelling percentage and quality aspects.
