Influence of transplanting wheat seedlings fertilization treatments and irrigation with treated sewage water on wheat productivity. 1. Growth characteristics [electronic resource].

Includes reference.

Two field experiments were carried out at sewage water plant at EI-Salhia EI-Gedida city, Sharkia governorate, Egypt during two successive seasons 2000/2001 and 2001/2002 to investigate the effects of some agronomic practices i.e. two planting methods and six fertilization treatments on productivity of wheat. Treated sewage water was used as a source of irrigation. Each experiment included 12 treatments which were the combination of two planting methods and six fertilization treatments. Wheat cultivar Sakha 8 (Triticum aestivum, L.) was used. Treated sewage water was used as a source of irrigation water. Transplanting wheat seedling after 35 days from sowing had significant positive effects on number of tillers per plant, number of green leaves per plant and flag leaf area at 105 DAS. Drilling wheat seeds directly into the soil had significant effect on plant height, spike dry weight, total dry weight per plant and spike length. Increasing nitrogen and phosphorus levels had significant positive effect on plant height, flag leaf area, number of green leaves/plant, and total plant dry weight. While, number of tillers, spike dry weight, number of spikes/plant and spike length were not affected significantly by increasing nitrogen and phosphorus levels. Irrigation with treated sewage water + 60 kg N + 0 kg P₂O₅ or0 kg N + 31 kg P₂O₅ produced the tallest plants compared to other fertilization treatments and control treatment (0 kg N + 0 kg P₂O₅). Irrigatioh with treated sewage water only or with adding 31 kg P₂O₅ had not significant effect on flag leaf area comparing to the other fertilization treatments. Application of 0 kg N + 31 kg P₂O₅ plus irrigation with treated sewage water or irrigation with treated sewage water only produced the shortest spike length.
