Effect of sources of nutrient and biofertilizers on productivity and profitability of Mungbean (Vigna radiata L.) in Kandahar region of Afghanistan

摘要

A field experiment was conducted during spring-summer season of 2017 at Tarnak Research Farm, ANASTU, Kandahar, Afghanistan to know the effect of sources of nutrients and biofertilizers on yield attributes, yield and economics of Mungbean. The designof experiment was Split Plot Design (SPD) with three replications. Four nutrients sources (control, 30:60:40 kg N:P:K ha~(-1), 10 t FYM ha~(-1) and 15:30:20 kg N:P:K ha~(-1) + 5t FYM ha~(-1)) were assigned in main plots and 4 levels of biofertilizers [NoBiofertilizer (No BF), Rhizobium (Rhi), Phosphate solubilizing bacteria (PSB) + Vesicular Arbuscular Mycorrhiza (VAM) and Rhi. + PSB + VAM] in subplots. The soil of experimental field was sandy clay loam, well drained, and deep red grey in color. It belongs to the Desert and Oasis Agro-ecological Zone. The soil organic carbon content was 0.6%, low in available N (170 kg N ha~(-1)) available P (22.4 kg P_2O_5 ha~(-1)) available K (142.5 kg K_2O ha~(-1)) and neutral to slight alkaline in reaction (pH 8.3). Significantly superior yield attributes, seed, stover and biological yields were recorded from RDF 0.5+FYM 5 t ha~(-1) and with the application of Rhi.+PSB+VAM. The interaction effect with the combination of RDF 0.5+FYM 5 t ha~(-1) and Rhi.+PSB+VAM for these parameters was found best.
