Abstract:
Field experiment was conducted at wetlands farm of Tamil Nadu Agricultural University, Coimbatore during January to April 2019 to study the effect of sowing window and nutrient management on blackgram under rice fallow condition. The result revealed that blackgram under rice fallow condition is performing well to graded doses of nutrient. The experiment was laid out in a split plot design with treatment combination of main plot M_1- sowing next day after harvest, M_2- sowing 15 days after harvest and in sub plot four nutrient levels N₁-0%, N_2-50%, N_3-75% and N₄-100% of RDF replicated thrice. The result revealed that sowing 15 days after rice harvest combined with 100% RDF recorded better growth, yield parameter and yield in rice fallow blackgram. However, sowing 15 days after rice harvest combined with 75% RDF were on par with sowing 15 days after rice harvest combined with 100% RDF.
