Title : Effect of fertility, zinc and cow urine levels on wheat and its’s residual effect on succeeding fodder maize under dairy based integrated farming system of Varanasi tract

Abstract :

A field experiment was executed in line with split plot deign in triplicate in two successive years of 2016-17 and 2017-18 at the Agricultural Research Farm, Banaras Hindu University, Varanasi (U.P.) to contrast the effect of cow urine application at varying fertility and zinc levels on growth and yield of irrigated wheat (Triticum aestivum L.) and their residual effect on fodder maize (Zea mays L.). Two fertility levels (100 and 75% RDF), three zinc (0, 5 and 10 kg Zn ha-1) and cow urine levels (0, 12000 and 8000 l ha-1 equally applied at sowing and CRI and spike emergence) were applied. RDF at 100% in previous wheat evinced significantly maximum (p=0.05) rally in green and dry fodder yield of fodder maize through highest plant height and number of green leaf plant-1 as well as net returns with exception of SPAD value (Leaf chlorophyll content). In parallel, fodder maize response in the matter of green and dry fodder yield via highest plant height and number of green leaf plant-1 as well as net returns except SPAD value (Leaf chlorophyll content) was significant at 10 kg zinc ha-1. Nevertheless, it could not differ at the significance level with 5 kg Zn ha-1. However, various cow urine levels applied in preceding wheat crop were not exerting any residual effect on growth, yield and economics of maize, suggesting that residual effect of 100% RDF, 10 kg Zn ha-1 applied to previous wheat was remunerative to fodder maize under similar soil and weather conditions.
