Abstract
Two field experiments were carried out at a private Farm at El-Zarka Center, Damietta Governorate during 2008 and 2009 summer seasons to study the effect of planting density (15 X 15, 20 X 20 and 25 X 25 cm) and mineral nitrogen fertilizer and poultry manure only and in combinations as follows: 100 % N, 75 % N + 25 % poultry manure, 50 % N + 50 % poultry manure, 25 % N + 75 % poultry manure and 100 % poultry manure addition on two rice cultivars i.e. Egyptian hybrid rice 1 (H1) and local cultivar (Giza 178). The main parameters of growth, yield and its components of rice were recorded. The obtained results could be summarized as follows:
Overall, Egyptian hybrid rice 1 cultivar (H1) significantly surpassed the local cultivar (Giza 178) in all studied characters in both growing seasons.
Using planting spacing 20 X 20 cm significantly recorded the highest values of grain yield in both seasons. While, the narrow spacing at 15 X 15 cm recorded the highest values of plant height and straw yield. Moreover, the wider spacing at 25 X 25 cm recorded the highest values of number of days from planting to 50 % flowering, flag leaf area, panicle length, number of grains/panicle, weight of grains/panicle and 1000-grain weight in both seasons.
Application of 100 % mineral nitrogen fertilizer alone significantly increased all studied characters and markedly recorded the highest values of these characters in both seasons. However, application of 75 % N + 25 % poultry manure came in the second rank and may be recommended in view of economic costs and maintenance of environment.
According to the obtained results from this study, it can be concluded that, planting Egyptian hybrid rice 1 cultivar (H1) at the plant spacing 20 X 20 cm and application 100 % N or 75 % N + 25 % poultry manure could be recommend to raise rice productivity and alleviate environmental pollution under the environmental conditions at El-Zarka Center, Damietta Governorate.
