Abstract:

A field experiment was carried out during summer season of 2017 at research farm of TCA Dholi, Dr. Rajendra Prasad Central Agricultural University, Pusa, Samastipur (Bihar) to study the “Effect of plant geometry and weed management on nutrient uptake and economics of summer mungbean (Vigna radiata L.)” The experiment was laid out in randomized block design with three replications. The treatment comprised of three plant geometry i.e., 20 cm x 10 cm, 25 cm x 10 cm and 30 cmx 10 cm and five weed management practices i.e., weedy check, hand weeding at 15 and 30 DAS, Pendimethalin @ 0.75 kg/ha (pre-emergence), Quizalofop-ethyl @ 60 g/ha at 15 DAS and Imazethapyr @ 60 g/ha at 15 DAS. Significantly higher  NPK-uptake by the crop  was recorded under closer row spacing of 20 cm × 10 cm than wider row spacings. Similarly, hand weeding twice recorded significantly higher NPK uptake by crop and lowered NPK-depletion by weeds than chemical weeding except K- uptake. Closer row spacing of 20 cm× 10 cm recorded significantly higher gross returns, net returns and B: C ratio than wider row spacing of 25 cm × 10 cm and 30 cm × 10 cm. Among the weed management practices, hand weeding twice recorded significantly higher gross returns while the highest net return and B: C ratio were  associated with  Imazethapyr.
