| Abstract |
Two field experiments were conducted under highly calcareous soil conditions at Nubaria Agriculture Research Station during two successive seasons of 1999/2000 and 2000/2001 to study the response of wheat (Triticum aestivum L.) to combined effect of N-fertilizer levels (0, 30, 60, 90, and 120 kg N/fed), (fed = 4200 m2), under different rates of farmyard manure (FYM) (0, 5, 10 and 15 m3 fed-1) in a split plot design. A quadratic polynomial equation (QPE) was used to describe the response of grain (GY), straw (StY) and biological yields (BY) as well as N, P and K uptake by grain and whole plant.
The obtained results indicated that, in both seasons increasing N-fertilizer levels resulted in significant increase in grain, straw and biological yield excepted for the differences between the highest two levels (90 and 120 kg N fed-1). Nitrogen use efficiencies (N use efficiency NUE, utilization efficiency NUtE, uptake efficiency NUpE, and grain N accumulation efficiency GNAE) decreased with increase N fertilization level while it was increased with increasing FYM application. Insignificant effects were obtained for the interaction of FYM and N-fertilizer levels. The maximum grain, straw and biological yields (18.9 Ardab fed -1 , 4.8 and 7.5 ton fed-1, respectively) were obtained from the combination of (15 m3 FYM and 90 kg N fed-1.
The QPE appeared to be sensitive and capable to illustrate the response of wheat GY, StY and BY as well as N, P and K uptake to the applied N fertilizer under different FYM rates. The obtained values of R2 (>0.860) reflecting highly significant correlations at the 0.01 level over the two growing seasons. Generally under, this experiment conditions, the combined application of (15m3 FYM and 90 kg N) fed-1 is the best treatment. It results in maximum grain yield and uptake of N, P and by wheat plants and enhanced N-use efficiencies.
