SUMMARY
The present investigation was carried out to study the effects of varieties and fertility levels on growth, fodder yield and nutrients of summer greengram. The experiment was comprised of three varieties viz., V1– MH-421, V2– MH-318 and V3– SML-668 as main plot treatment and four different fertility levels viz., T1 – Control, T2 – 100% RDF (20:40:0 kg/ha NPK), T3 – 75% RDF (inorganic) + 25% N/ha (FYM) + seed treatment (Rhizobium + PSB) and T4 – 50% RDF (inorganic) + 50% N/ha (FYM) + seed treatment (Rhizobium + PSB) as sub plot treatments. Experiment was laid out in split plot design with four replications. Summer greengram variety, MH-318 recorded significantly dry matter accumulation (g/plant) over SML-668 and MH-421 at 30 DAS (1.72), 45 DAS (9.01) and at harvest (15.5). MH-318 also exhibited significantly higher nitrogen (3.73, 2.27) and phosphorus (0.40, 0.28) content in grain and straw respectively as compared to SML-668 and MH-421. However, no significant variation was found concerning potassium content in grain as well as straw. NPK uptake in grain and straw was found significantly higher under MH-318 over SML-668 and MH-421. Higher protein content (23.3%) and straw yield (3020 kg ha-1) were recorded under MH-318 in comparison to other two varieties. Among fertility level treatments, 75% RDF (inorganic) + 25% N/ha (FYM) + seed treatment (Rhizobium + PSB) recorded significantly higher dry matter accumulation over other treatments. NPK content & uptake, protein content (23.7%) and straw yield (3395 kg ha-1) was also significantly higher with the application of 75% RDF (inorganic) + 25% N/ha (FYM) + seed treatment (Rhizobium + PSB) over 50% N/ha (FYM) + seed treatment (Rhizobium + PSB), 100% RDF (20:40:0 kg/ha NPK) and control. Thus, the variety MH-318 should be fertilized with 75% RDF (inorganic) + 25% N/ha (FYM) + seed treatment (Rhizobium + PSB) to obtain grain & straw yield and economic returns of summer greengram.
