| Abstract | ||
| Two field experiments were conducted at the Experimental Farm of Water Requirements Research Station, Kafrelsheikh Governorate, North Delta, Water Management Research Institute, National Water Research Centre, Egypt,during 2010 and 2011 seasons, to study the effect of mineral and organic nitrogen fertilizers on rice productivity under traditional transplanting and transplanting in bottom of beds methods and so on water saving and its use effeciency under the conditions of Kafrelsheikh Governorate for rice cultivar Sakha 105. Fertilizer treatments were as following (160 kg N/ha, 120 kg N/+ 5 tons compost/ ha and 80 kg N + 5 tons compost/ ha). Treatments were arranged in split plot design with four replicates. The main plots included the two planting methods, while, the three fertilizer treatments were allocated at the sub plots. The obtained results could be summarized as follows: The results reveal that the method of planting in bottom of beds led to significantly increased in dry weight at heading, 1000 grain weight, grain yield and harvest index in both seasons as well as number of grains/panicle in the second season compared with the method of traditional transplanting, which recorded a highly significant values in plant height, number of panicles/hill in both seasons and straw yield in the second season. Data show that planting in bottom of beds led to significant increase in water use efficiency and achieved water saving of 4798 and 4788 m3/ha ( 2016 and 2012 m3/fed.) in the first and second seasons, respectively as compared with traditional transplanting method. The obtained results show that application of mineral nitrogen 120 kg N in combined with 5 tons compost/ha significantly recorded the highest values of plant height number of panicles/hill, number of grains/panicle, 1000 grain weight,grain and straw yields and harvest index in both seasons as well as dry weight only in the first season . The treatment of 160 kg N/ha didn't significantly differed with the treatment of 120 kg N + 5 tons compost/ha in 1000 grain weight in the first season, grain yield in the second season and harvest index in both seasons. From the obtained results under these conditions of this study, it could be concluded that planting rice in bottom of beds saved water in average of 4793 m3/ha and increased water use efficiency as compared with traditional transplanting. Also, application of 5 tons compost plus 120 kg N/ha gave the highest productivity of rice cultivar Sakha 105 Kafrelsheikh. | ||
