Influence of organic and inorganic fertilizers on the yield of blackgram
Abstract
Flower abortion and pod dropping are the main bottleneck for the expansion of blackgram production in Bangladesh. In view of partial solution on this problem an experiment was conducted to study the influence of different combinations of organic and inorganic fertilizer on yield of blackgram. Treatments consisted of two combined organic and inorganic varieties viz., V1= BARI Mash-2, V2= BARI Mash-3, eight levels of fertilizers viz., F0 = Control, F1 = RDF, F2 = 25% less than RDF + Vermicompost, F3 = 50% less than RDF + Vermicompost, F4 = 25% less than RDF + Poultry litter, F5 = 50% less than RDF + Poultry litter, F6 = 25% less than RDF + Mixed fertilizer, and F7 = 50% less than RDF + Mixed fertilizer. The experiment was conducted following Randomized Complete Block Design (RCBD) with 3 replications. Results revealed that the yield of blackgram were significantly influenced by varieties and/or organic and inorganic fertilizers. Between two varieties, BARI Mash-3 gave the highest seed yield (1.83 t ha-1). Among the fertilizer dose, F2 gave the highest seed yield (1.84 t ha-1) which was statistically similar to F1 (1.82 t ha-1) and F3 (1.79 t ha-1). The highest seed yield (1.90 t ha-1) was exhibited from V2F2treatment combination followed by V2F1 (1.87 t ha-1). It can be concluded that the application of organic and inorganic fertilizer had a positive effect on BARI Mash-3 and 25% less than recommended dose of fertilizer + vermicompost or recommended dose of fertilizer can be suggested to cultivate this crop.
