Study on Effect of Fertilizer and FYM Application on Black Gram (Vigna mungo L. Hepper) in Relation to Seed Yield and its Component Characters in Hilly Area of Nagaland

The experiment was conducted at Medziphema, foothills of Nagaland to study the performance and yield of fourteen genotypes of black gram (Vigna Mungo L. Hepper) on two different treatments – one with fertilizer @ 20:40:20 NPK Kg/ha, the other with FYM @ 20 tons/ha and without any treatment i.e., control. The experimental design used was RBD. Theplot size was 1.5 x2 m² with a spacing of 30 cm row to row 10 cm plant to plant. Data on eight characters were under study. Based on the analysis of variance it was revealed that significant differences were existed of all the characters among the genotypes. Further, significant differences due to environment (linear) indicated that the performance of the genotypes could be predicted. Analysis of variance (mean squares) for different characters in three different environments (Table-II) showed significant differences in E3 (FYM treated soil). Environmental means for different characters in three different environments (Table-III), indicated that soil treated with FYM @20 tons/ha was found to be the best in terms of seed yield and other yield attributing characters under the foot hill conditions of Medziphema, Nagaland.
