Abstract:
A field experiment was carried out to study the nutrient budgeting in some important vegetable based cropping sequences for two consecutive year, 2010-11 and 2011-12 during summer, kharif and rabi season at Horticultural farm, BAU, Ranchi. The negative N balance was observed in almost all treatments after two years of experimentation. The highest net loss (-118.00 kg/ha) of N, after two years was observed in watermelon-maize-pea whereas, it was lowest (-53.00 kg/ha) in bottle gourd-chilli-radish sequences. The net gain of P after two years was in ridge gourd-cowpea-tomato and bottle gourd-chilli-radish sequences with +2.00 and +7.00 kg/ha, respectively whereas, net loss of P was observed in rest of the sequences. The negative K balance was observed in almost all sequences except bottle gourd-chilli-radish (+36.00 kg/ha) and okra-maize-cabbage (+16.00 kg/ha) sequences, where there was gain in net potassium. The rice equivalent yield was obtained higher in sponge gourd-rice-broccoli (144.40 q/ha) sequences and was at par with ridge gourd-cowpea-tomato (143.34 q/ha) and sponge gourd-brinjal-capsicum (124.89 q/ha) sequences. At the completion of two years experiment, highest (3.26) benefit: cost ratio was observed in sponge gourd-rice-broccoli sequence.
