Effect of Nitrogen, Potach and Transplanting Regularity on Rice Crop Productivity

Abstract: ABSTRACT
Two field experiments were conducted at the farm of Faculty of agriculture, Kafr El-Sheikh, Egypt, during the two successive seasons of 2003 and 2004. The present study aimed to study the impact of three nitrogen levels; 0, 40, & 60 kg /fed., three potassium levels, 0, 30 & 60 kg k2o/fed on under regular and irregular transplanting on growth, yield, yield components and some chemicals contents of Giza 178 rice cultivar . The experiments were laid out in strip split plot design with four replication. The nitrogen and potassium levels were distributed in the first and second main plots, respectively while transplanting regularity occupied the sub plots. The main results could be summarized as following:
The nitrogen levels had positive and significant effect on flag leaf area, plant height, tillers number, panicle length, panicles number, filled grains/panicle, panicle weight, 1000-grain weight, grain yield, straw yield harvest index, potassium content and nitrogen content. Increasing nitrogen levels up to 60 kg N/fed significantly increased the above mentioned traits.
The economic level of potassium fertilizer (30kg k2o /fed had favorable effect on the studied traits was 30 kg K2O /fed regarding growth yield attributing characters, yield and nitrogen content. Potassium level of 60 kg k2o/fed. gave the highest value on potassium content in grain .The regularity of transplanting had pronounced effect on the majority of the studied characters involving grain yield. The regular transplanting exceeded the irregular transplanting in all studied traits. Some interaction had significant effect on some trait, and it would be discussed in the text of the paper.
