Effect of some Soil Preparation Systems on the Amount Water Added and Emergence Percentage for Egyptian Clover

Abstract

Field experiments were carried out in a clay soil during season of 2020 at Arumon village, Kafr El-Sheikh Governorate. The aim of this work was to achieve effect of some soil preparation systems on the amount of water added with three irrigation conditions (irrigation for agriculture, irrigation for urgency and irrigation after 12 days of previous irrigation) and seeds emergence percentage for Egyptian clover yield so productivity of the first mowing. To fulfill this goal, the following experiments were used; the chisel plow at a depth of 15 cm (one pass) followed by laser land leveling (T1); the chisel plow at a depth of 15 cm (one pass) followed by traditional land leveling (T2), and the used land with rice residues left on it without leveling (T3). The planting was carried out by manual broadcasting (30 kg / fed) on all experiments, and all planting treatments were content under all above variables.-The minimum height and amount of water on the breeding surface after irrigation were 51 mm and 214.2 m 3 /fed, respectively, these results was obtained by using T1, while for the maximum values were 152 mm and 586.6 m 3 /fed, respectively, these results were obtained by using T3. -The maximum seeds emergence percentage, productivity of the first mowing and water use efficiency were 65%, 29.1 Mg/fed and 0.14 Mg/m 3 , respectively, these results was obtained by using T1, while for the minimum values were 33%, 16.4 Mg/fed and 0.028 Mg/m 3 , respectively, these results was obtained by using T3.
