| Abstract |
Two field experiments were carried out in clayey soils during the two successive summer seasons 2003 and 2004. The first was at Sidi Salem district and the second at Sakha Agricultural Research Station Farm, Kafr El-Sheikh, Egypt.
The objectives of the present study are: increasing corn yield, decreasing the applied mineral nitrogen fertilizers, safe rid of farm manures, and saving water by better surface irrigation management.
Corn (hybrid single cross 10) yield was evaluated in a split plot design with four replicates. The main plots were assigned to four surface irrigation methods of 1- every furrow irrigation., 2- alternative furrow irrigation., 3- surge irrigation, and 4- cut of 85% of furrow length. The sub plots were assigned to five fertilization treatments of:
1- application of the recommended dose of the mineral nitrogen fertilizer (286 kg mineral N ha-1),
2- Application of 14.4 ton compost ha-1,
3- Application of 14.4 ton compost + 214 kg mineral N ha-1
4- Application of 14.4 ton compost + 143 kg mineral N ha-1
5- Application of 14.4 ton compost + 71 kg mineral N ha-1.
The results can be summarized as follows:
1. The highest corn yield values 11366, 12840 kg ha-1 were obtained with the surge irrigation, while the lowest with the cut of 85% of furrow length method.
2. Management of surface irrigation saved irrigation water by 28.5 and 21.7% with the alternative furrow irrigation, 20.00 and 13.7% with the surge irrigation, and 12.5 and 12.9% with the cut of 85% of furrow length in the first and second season, respectively compared with every furrow irrigation method.
3. The highest corn yield values 13700, 13157 kg ha-1 were obtained with 14.4 ton ha-1 compost + 214 kg N ha-1 in the first and second season, respectively.
4. The highest water use productivity values were obtained with the interaction between the surge irrigation with 14.4 ton ha-1 compost +214 kg mineral N ha-1.
5. The obtained results show that the highest corn yield was associated with the treatment of 14.4 ton compost + 214 kg N ha-1, where it reduced the N fertilizer by 25%, and saving irrigation water by 20.00 and 12.9% in the first and second seasons, respectively
