Effect of biofertilizers in conjunction of phosphorus on growth, yield attributes, yield and economics of maize (Zea mays L.)

Abstract

An investigation was made during kharif season of 2016 at M.G.C.G.V., Chitrakoot to see the effect of biofertilizers on maize. It is evident from the results that application of 60 Kg P­2O5 + NPK consortia proved to be the best treatment as it gave the superior yield attributes viz. Cobs/plant (1.20), cob weight (184.92g), seed weight/plant (116.01g), 1000-seed weight (212 g ), cob length (20.07 cm) and cob girth (13.35cm); cob yield (11934 kg/ha) grain yield (4990 kg/ha), stover yield (9854 kg/ha), gross returns (Rs. 159555/ha) and net returns (Rs. 136549/ha). Treatment T2, T3, T4, T5, T6, T7, T8, T9, T11 and T12 produced higher grain yield of maize to the tune of 129 kg (1.69%), 193 Kg (5.24%), 373 kg (10.12%), 356 kg (9.66%), 802 Kg (21.76%), 721 Kg (19.57%), 254 Kg (6.89%), 725 Kg (19.7%), 795 Kg (21.57%), 1305 Kg (35.41%) and 458 Kg/ha (12.43%) over control, respectively. Plant population plant height, leaves/plant and dry weight/plant were not affected significantly due to biofertilizer treatments.
