Effect of Sulphur Fertilization on Growth and Yield of Mu Gbea (Vigna Radiata .l. Wilczek) in the Agro Ecosystem of Western Uttar Pradesh

Abstract

Pulses are the major constituent of Indian diet for providing protein rich food to vegetarian masses and improve the soil health, however, due to poor productivity the share towards global pulse production is just 26.0% as against 36.6% share in area (Singh and Vashist, 2005). Thus, despite increase in production, per capita pulse availability has decline from 64 gram per capita per day during (1950-51) to 45 gram per capita per day in 1970 as against WHO nonns of 80 gram per capita per day (WHO, 1976). To meet out the growing protein requirement, mungbean (Vigna radiata L. Wilczek) may play a prominent role among pulses. Keeping above facts in view, the investigation was carried out at crop research centre of Sardar Vallabhbhai Patel University of Agriculture and Technology Meerut Western Uttar Pradesh region during spring season 2010. Field experiment was conducted for mungbean, consisting 17 treatments combination and laid out in randomized block design (RBD) with 3 replications. The genotype tested for mungbean was SML-668. The effect of sulphur had remarkable affect on growth and yield behavior of mungbean. Treatment T15 combination of (100% NPK+S) was found maximum plant height, number of trifoliate, dry matter accumulation, number of branches and also to be found significantly on phenological stages viz. days taken to flowering, podding, maturity and root nodulation studies, RuBP carboxylase and leghaemoglobin content. Treatment T15 was observed significantly superior to all treatments in relation to yield attributes viz. number of pods planr\ number of grains pod-1, 1000 grain weight and grain yield planr1 excep~ T1s. Similar trend were noticed in respect to strover and harvest index. The max1mum NPK content and uptake by mungbean varied significantly in T1s (100% NPK+S). Treatment T1s combination of (1 00% NPK+S) had remarkable affect on ~ross return (22902.33 Rsha-1) higher net return (14560.33 Rs.ha·1> and B:C rat1o (1 .7), however, the decline yield was found in other treatments parameter.
