Effect of Polymer Coating, Chemicals and Biocontrol Agent on Storability of Black Gram (Vigna mungo L.)

摘要

The present storage experiment was conducted at Seed Testing Laboratory, Department of Genetics and Plant Breeding, Sam Higginbottom Institute of Agriculture, Technology & Sciences (SHIATS), Allahabad, Uttar Pradesh during 2014 - 2015 with black gram cv. T-9 obtained from Department of Genetics and Plant Breeding, SHIATS. The seeds were coated with polymer in combination with fungicide (thiram 3 g/kg seed), insecticide (imidacloprid @ 2.5 ml/kg seed), bioagent ( Trichoderma viride @ 10 g/kg seed) and maintained untreated seeds (control) where T₁ is polymer coat alone, T₂ is polymer + thiram, T₃ is polymer + imidacloprid, T₄ is polymer + thiram + imidacloprid, T₅ is polymer + thiram + imidacloprid + Trichoderma viride and T₆ is control. Treated seeds were packed in cloth bag and polythene bag (700 gauge) (factor C₁ and C₂) at ambient conditions for assessment of seed germination, seedling length, seedling dry matter, seedling vigour indices, moisture content, total fungal colonies and protein content where data was subjected to factorial experiment laid out in completely randomized design. Germination percentage, root length, shoot length, seedling length, seedling dry weight, seedling vigour indices and protein content were high in T₅C₂ as compared to all other treatments. However, total fungal colonies and moisture content were less in T₅C₂.
