Abstract
A field experiment was carried out at El-Roba village, Baltim, Kafr El- Sheikh Governorate, Egypt during two consecutive growing summer seasons 2004 and 2005 to study the effect of irrigation regimes, organic manure and source and levels of nitrogen fertilizers on zea maize yield and nutrient contents.
The obtained results could be summarized as follows:
The highest values of N concentration in ear leaf (1.89%) in the 1st season as well as P concentration (0.323 and 0.319 %) and K concentration (2.62 and 2.67 %) in both seasons were obtained from zea maize plants irrigated at 1.3 evaporation pan coefficient with applying 10 m3 chicken manure fed-1 and fertilized with enciabeen at 320 kg N fed.-1.
The highest values of ear diameter (5.48 cm) and N concentration (1.94 %) in the 2nd season and grain yield (28.69 and 30.1 ardab fed.-1) in both seasons were obtained from zea maize plants irrigated at 1.3 evaporation pan coefficient, fertilized with 10 m3chicken manure fed.-1 and fertilized with urea at 160 kg N fed.-1.
The highest values of ear diameter (4.5cm) in the 1st season and 100-grain weight (32.91 and 33.3 g ) in the 1st and 2nd seasons were obtained from zea maize plants irrigated at 1.3 evaporation pan coefficient, fertilized with 10 m3chicken manure fed.-1 and fertilized with urea at 240 kg N fed.-1.
From these results, it could be concluded that the application of irrigation water at 1.3 evaporation pan coefficient could be recommended with zea maize for high production under North Delta conditions.
