Abstract
In the study, the residual effect of farmyard manure (FYM) given to previous wheat was evaluated on the next maize crop. A three-crop based experiment maize (control)-wheat-maize from summer 2007 (Kharif) to summer 2008 (Kharif) was performed. Standard dose of FYM was given to the field of intermediate wheat crop. Different NP doses were applied in the four treatments. Residual effect of FYM was estimated out on seven parameters viz; plant height (cm), ear height (cm), cob length (cm), grain row/cob, grains/row, 1000 grains weight (gm) and grain yield/plot (kg). All the parameters exhibited significant results after FYM application except grains/row. Except the ear length, replications remained non-significant. Plant height, cob length and grain yield/plot exhibited fairly significant results with different treatments, while other four parameters remained non-significant. No interaction found between treatments, and before and after FYM application except in 1000 grains weight. Overall 21.37% increase in grain yield/plot was observed. We suggest the application of N 90 kg ha-1 + P 60 kg ha-1 (T2) and N 120 kg ha-1 + P 80kg ha-1 (T3) with standard dose of FYM (6000 kg ha-1) on the previous crop to get better yield of upcoming maize crop in arid regions of Pakistan.
