| Abstract | ||||
| A field trial was carried out during 2008 and 2009 summer seasons at the Experimental Farm of the Faculty of Agriculture, Fayoum University. The aim work was to study the effect of farmyard manure (FYM) and mineral N fertilizers on yield and its components of "TWC310" maize hybrid. Three FYM rates, i.e., 15 (M1), 30 (M2) and 45 (M3) m3/fed. and three levels of mineral nitrogen, i.e., 90 (N1), 120 (N2) and 150(N3) kg N/fed. of ammonium nitrate were examined. The field was prepared as recommended and the experiment was laid out in a split plot arrangement in RCBD with four replications. Results revealed increasing positive response of maize to FYM up to the largest amount of M3 that seemed to be large enough to release N throughout the growing season and produced the highest values of all the studied traits. The second rate of FYM (M2) showed similar values for some traits which initiated at early time of development. Whereas, the smallest rate of FYM produced relatively inferior trait values. Grain yield of M3 surpassed those of M2 and M1 by 5.24 and 16.61%, respectively. Intermediate mineral fertilizer (N2) application produced the tallest plants with the highest ear position. However, N3 resulted in superior values of other traits, with insignificant differences for grain weight/ear and grain yield/faddan of those of N2. Grain yield produced with M1, M2 and M3 of FYM applications were respectively comparable to those of N1, N2 and N3 indicating that mineral fertilizer (N) could be replaced by FYM in such soil. The N1 application combined with either M2 or M3 improved plant and ear heights. The M2N3 and M3N3 interactions were of the highest and had similar effects on ear weight (92.63 and 90.88g) grain weight/ear (75.88 and 72.13g) and grain yield/faddan (1745.1 and 1658.9 kg). The M3N2 and/or M2N3 combinations produced higher grain yield than those of sole application of either organic or inorganic N fertilizer. | ||||
