Effect of Organic Sources of Nutrients on Yield and Economics of Black Gram

Year: 2024
Type: article
Abstract: A research to study the effect of organic sources of nutrients on yield and economics of black gram was conducted at new experimental cum demonstration field, SVIAg, SVVV, Indore. The experimental soil was medium black clay in texture with low in available nitrogen (208.22 kg ha-1), medium in phosphorus (15.12 kg ha-1) and high in potassium (456.58 kg ha-1). The soil organic carbon content, pH, and EC was 0.50 per cent, 7.35, and 0.70 dSm-1 respectively. The experiment consists of nine treatments and replicated three times in Randomized Block Design which consists the use of poultry manure, vermicompost and different bio inoculants. The treatments includes T1: Absolute control, T2: Vermicompost manure (2 ton ha-1), T3: Poultry manure (2-ton ha-1), T4: Vermicompost manure (2 ton ha-1) + Rhizobium, T5: Vermicompost manure (2 ton ha-1) + PSB, T6: Poultry manure (2 ton ha-1) + Rhizobium, T7: Poultry manure (2 ton ha-1) + PSB, T8: Vermicompost manure+ Rhizobium + PSB and T9: Poultry manure + Rhizobium + PSB. Application of poultry manure + Rhizobium + PSB recorded highest yield and yield attributes such as no. of pods plant-1 (19.93), pod yield plant-1 (8.40 g), seed yield plant-1 (5.38 g), seed yield (8.48 q ha-1), straw yield (10.79 q ha-1) and biological yield (17.22 q ha-1) at harvest and was found to be at par with application of vermicompost + Rhizobium + PSB treatments. The highest value of gross monetary returns (₹ 71107.88 ha-1), cost of cultivation (₹ 51780.65 ha-1), net monetary returns (₹ 19327.23 ha-1) and B:C ratio (1.37) was recorded from treatment with the application of poultry manure + Rhizobium + PSB followed by treatment receiving vermicompost + Rhizobium + PSB treatment.
