Abstract:
A field experiment was conducted on Effect of integrated nutrient management on growth and yield of blackgram (Vigna mungo L.) during Kharif 2021 at Krishi Vigyan Kendra, Ambikapur. The experiment was laid out in randomized block design replicated thrice with seven nutrient management treatments viz. T₁-100% RDF (20:40:20 kg N:P:K ha^-1), T₂-100% RDF + Rhizobium + PSB, T₃-75% RDF +Vermicompost @ 1 tonne ha^-1, T₄ -75% RDF +Vermicompost @ 1 tonne ha^-1+ Rhizobium + PSB, T₅- 50% RDF + Vermicompost @ 2 tonnes ha^-1, T₆ - 50% RDF + Vermicompost @ 2 tonnes ha^-1 + Rhizobium + PSB, T₇- Vermicompost @ 2 tonnes ha_-1 + Rhizobium + PSB. Studies revealed that the growth characters viz. plant height, branches plant^-1, dry matter accumulation, crop growth rate, yield attributes viz. pods plant^-1, seeds pod^-1 and test weight, grain yield and stover yields were influenced significantly by different nutrient management practices. The maximum values of these parameters were recorded under the treatment T₂- 100% RDF + Rhizobium + PSB which was at par with T₄-75% RDF +Vermicompost @ 1 tonne ha^-1+ Rhizobium + PSB. However, the application of 100% RDF (20:40:20 kg N:P:K ha^-1) also recorded next superior except above two treatments.
