Effect of Planting Dates and Planting Methods on Water Relations of Wheat

Wheat (Triticum aestivum L.) is the uppermost cereal grain crop considered as a major stable food for the Egyptian people. Field experiments were conducted during two consecutive winter seasons of 2017-18 and 2018-19 to study the effect of two planting dates (PD) (20(th) of November and 20(th) of December) under four different planting methods (PM) (bed broadcast, flat broadcast, drill at 15 cm, and drill at 25 cm apart rows) on the productivity and water relations of wheat genotype (Egypt 1). The study is intended to assess the water relations for wheat planting dates and planting methods and determine the role of late planting date and planting methods on wheat productivity. Results showed that the values of grain yields and some attributed yields were highly significantly affected by planting dates and methods in the two growing seasons. Planting wheat at the optimal date (20(th) November) was better than sowing at the late date (20(th) December) for all values obtained from the studied parameters in both seasons of the study. The bed broadcast planting method gave the highest mean values for all studied parameters except the plant height which was recorded with drilling seeds at a 15 cm planting method in the two growing seasons. The highest values of water applied were recorded with the first date under the borders planting method (PD1M2), while the lowest of Aw recorded was from beds planting method with the second date. The highest mean values for WP were recorded with the bed broadcast planting method.
