Effect of Planting Techniques, Rhizobium Inoculation and Micronutrients on Performance Of Mungbean (Vigna Radiata L.) and Their Residual Effect on Wheat Crop

Abstract

The field experiment wa~ conducted at Crop Research Centre of Sardar \'allabhbhai Patel ljniversit} of Agriculture and Technology. Modipuram. Meerut U.P. to srud} the -Eilect of planting techniques. Rhi::obium inoculation and micronutrients on performance of mungbean (Vig11u radiata Lj and their residual cOI:ct on v.heat crop" during 2009-10 and 2010-11. Twenty four treatment combinations comprised of three treatments of planting technique (flat bed. nnrro" raised bed and wide raised bed),two treatments of seed inoculation (Rhi:obtum inoculation and non-inoculation) and four trentmcnb of micronutrients (Control. Iron We) @ 0.25% foliar spray nt 25 and 40 DAS, Mol}bdcnum (Mo) @ 0.25% foliar spray at 25 and 40 DAS und l'e ,.. Mo@ 0.25% foliar spray at 25 and 40 DAS) were te,ted in split-split plot design v.ith three replications. These treatments \\Cre applied in mungbean "SML-668" \\ith follo"ing obJecti\cs: I.To assess the effect or plaming techniques. Rili::Qbium inoculation and micronutricnb on performance of mungbcan. 2.

This treatment }ielded 12.35 and 13.04 q ha'1 during 2009 and 20 I 0, respectively. Interaction between RIJizobium inoculation and micronutricnts (JxM) on grain yield of mungbean was found significant during 2009 and 20 I 0. Residual effect of mungbean increased the crop growth, yield attributes and ) ield of wheat crop. The highest grain ) ield 49.59 and 50.81 q ha·' of suc.:ceding ''heat crop \\ere re<:orded where mungbean residue was incorporated at "ide raised bed (PJ) which was significantly higher O\er flat bed (P,) during 2009-10 and 2010-11, respecti\ely. On the basis of ec'onomics of mungbean, the highest net return \\Us recorded with the foliar spray of Fe + Mo (@ 0.25% at 25 and 40 DAS. along with the highc~t net income per rupee invested of R.s 3.50 and 3. 75 during 2009 and 2010
