EFFECT OF ORGANIC FERTILIZATION METHOD ON RICE CROP YIELD AND QUALITY

This study was carried out at El-Helaly Village, El-Dakhlia Governorate, during 2015 summer season to identify the effect of organic fertilization method on rice crop yield and quality. The experiment was established and designed statistically as a split plots with three replications. The main plots involved tillage treatment levels of moldboard plough followed by disc harrow, rotary plough as a minimum tillage and chisel plough (two perpendicular passes) followed by disc harrow. The sub plots included wheat straw application forms levels of wheat stubble and chopped wheat straw. The results indicated that the rotary plough accompanied with chopped wheat straw accomplished higher actual field capacity of 0.92 fed/h, lower specific energy requirements of 25.43 MJ/fed, lower seed drill wheel skidding of 2.55% and higher plant distribution uniformity of 94%. While, the moldboard plough followed by disc harrow and accompanied with chopped wheat straw achieved more desirable soil characteristics and higher rice grain yield of 4.36 Mg/fed. So, it is recommended to apply the moldboard plough followed by disc harrow and accompanied with chopped wheat straw as a proper organic fertilization method.
