摘要

A study was carried out at Kalabsho Region, El-Dakhlia Governor-ate, during 2012 summer season to identify the effect of organic fertilization on rice mechanical drilling, soil charactersties and total yield. Sugar beet tops were Used as an organic fertilizer. They were broadcasted upon the soil surface and tilled using a rotary plough. The experimental work was designed statistically as a split plots with three replications. The main plots involved the organic fertilization treatment with rotary ploughing (2 contrary passes), rotary ploughing (1 pass) and without rotary ploughing. The sub plots included seed drill with forward speed treatment levels of 2.25, 3.60, 4.95 and 6.30 km/h. The results indicated the following: 1. The seed drill at forward speed of 6.30 km/h after rotary ploughing (2 passes) achieved higher field capacity of 2.13 fed/h and lower specific energy of 1.21 MJ/fed. 2. The rotary ploughing (2 passes) achieved the best desirable soil characteristics of 1.28 g/cm3 bulk density, 18.11 mm/h infiltration rate, 2.14 dS/m salinity, 6.00 pH and 27.00, 18.20 and 347.00 ppm of the available N, P and K concentration, respectively. 3. The rotary ploughing (2 passes) achieved higher plant uniformity coefficient of 93 % and higher rice grain yield of 4.40 Mg/fed. Generally, it is recommended to apply the chisel plough and rotary ploughing (2 passes) for sugar beet top mixing as an organic fertilization method of soil to achieve higher rice grain yield.
