ABSTRACT

Heavy textured soil leads to insufficiency of water in arid region. To investigate the effect of soil pulverization (P) and sowing methods (S) on Water Use Efficiency (WUE), wheat yield and economics, a field experiment was carried out at Arid Zone Research Center, Dera Ismail Khan, Khyber Pakhtunkhwah Province, Pakistan, during rabi season of 2014-15 and 2015-16. The experiment was laid in randomized complete block (RCB) design with split plot arrangement keeping pulverization viz. single tiller P1, double tiller P2, triple tiller P3 and mould board plow P4 followed by single rotavator in main plots while sowing methods i.e. Raised Bed Sowing S1and Flat Bed Sowing S2 in the subplots. The results showed higher WUE in the plots receivingP2and S1 in both years of experiments. Statistics revealed that P had significant effect on tillers plant-1, weight of grain spike-1, grain yield and harvest index % (H.I. %). While (S) had significant effect on yield of grain, straw, biomass and H.I. Maximum grain yield and BCR was recorded in treatment combination of P2 × S1.It is concluded that use of 2-tillers on raise bed sowing method gave significant result of WUE, economics and grain yield which may be recommended for the arid regions.
