Trends in Biosciences

An experiment was conducted for three years at Pulses Research Sub-Station, Habak, SKUAST-K during kharif seasons from 2006 to 2008 to study integrated phosphorus management in mungbean. Ten treatments viz., control; 30:50:30kg NPK/ ha; 30:50:30kg NPK/ha+Rhizobium;5t FYM/ha+30:50:30kg NPK/ha +Rhizobium +PSB; 10t FYM/ha +15:25:15kgNPK/ ha+Rhizobium+PSB; 10t FYM/ha +20kg P₂O₅ as Phosphate Rock + PSB; 5t FYM/ha +40kg P₂O₅ as Phosphate Rock + PSB; 10t FYM/ha +20kg P₂O₅ as DAP+PSB and 5t FYM/ha + 40kg P₂O₅ as DAP + PSB were replicated thrice in RBD. Growth, yield contributing characters and grain yield were significantly enhanced under different treatments. Highest grain yield (918 kg/ha) was recorded under 5t FYM/ha +30:50:30kg NPK/ha +Rhizobium +PSB which was 72.22% higher over control that gave the lowest yield (518 kg/ha). It also recorded highest values of plant height, pods per plant, nodule count and test weight. 5t FYM/ha conjugated with 40Kg P₂O₅ through rock phosphate + seed inoculation with PSB gave mungbean yield (801kg/ha) that was at par with 30:50:30kg NPK/ha +Rhizobium (803kg/ ha) & 5t FYM/ha +40kg P₂O₅ as DAP + PSB (829kg/ha). 5t FYM/ha + 30:50:30kg NPK/ha + Rhizobium+PSB procured highest net return (Rs. 18320) and B.C. ratio (1:34).
