Abstract
A field experiment was conducted during kharif season of 2018-19 in D-6 Block of the Norman E. Borlaug Crop Research Centre of G.B. Pant University of Agriculture and Technology, Pantnagar to study the effect of row spacing on growth & development, yield and yield attributing characters, quality, nutrient content and uptake (N, P and K) of mungbean genotypes, and economics of different treatments. The soil of the experimental site was sandy loam in texture having high organic carbon (0.85%), medium available nitrogen (308.2 kg/ha), high available phosphorus (26.7 kg/ha) and medium available potassium (239.8 kg/ha) with slightly acidic to neutral soil reaction (7.1). The experiment was conducted in randomized block design with three replications and two factors consisting of two row spacing viz., 30 × 10 cm and 45 × 10 cm
and six genotypes namely KMA 18-326, KMA 18-327, KMA 18-328, KMA 18-329, Pant Mung 5 and Pant Mung 8. The results obtained during the course of the experimentation revealed that the row spacing of 45 × 10 cm, with 2,22,222 plants/ha, significantly increased all the growth
parameters, except the plant height, resulting in higher yield attributes, seed yield, protein yield, nitrogen uptake, net returns and B: C ratio as compared to that of 30 × 10 cm row spacing which had 1.5 times more plants. The increment in seed yield at the row spacing of 45 × 10 cm was 12.6% more over that of 30 × 10 cm row spacing. Among the genotypes, Pant Mung 8 was significantly superior over the other genotypes in terms of yield and yield attributing characters, N, P and K uptake, protein yield and B: C ratio. Pant Mung 8 recorded 25.9%, 31.9%, 36.7% and 40.7% higher seed yield than that of KMA 18-327, KMA 18-326, Pant Mung 5 and KMA 18-328, respectively. Hence, for achieving higher
yield of mungbean, in tarai region of Uttarakhand, genotype Pant Mung 8 and a row spacing of 45 × 10 cm seems a better prospect.
