The Effect of Application of Different Rate N-P Fertilizers Rate on Yield and Yield Attributes of Bread Wheat in Case of Chancha Woreda Southern Ethiopia

Abstract

Nitrogen  and phosphorous is the most essential elements for the plant growth and to boost the yield of crops but the most tropical soils including the Ethiopian soils are poor in the availability of the nitrogen and the phosphorus elements for these reasons the yields of the crops gradually declining. For these reasons the experiments conducted on farmers FTC   AT Cahcha woreada southern Ethiopia by using two (2) levels of nitrogen and the four (4) levels of phosphorus fertilizers levels are laid out completed block design with three replications The ANOVA confirmed that there is a significant difference between the yield and growth parameters of the wheat variety Denda. within the growth parameters the highest mean was spike length recorded from with the application of 50kg/ha of nitrogen and 150 kg/ha phosphorus fertilizers while the lowest was recorded from the negative control treatments and the highest mean of the plant height 87.2cm was recorded from the application of the 50 kg/ha of nitrogen and 100kg of phosphorus. From the yield parameters the highest grain yield 63.96/ha  quintals  was obtained from  the application of the 50 kg/ha of nitrogen and the application of 150kg/ha phosphorus fertilizers likewise the highest mean of the biomass yield 1599 kg/plot was obtained from the application of 50 and 150 kg/ha nitrogen and phosphorus fertilizers respectively treatments. From the above fined the use of 50kg/ha of nitrogen and 150 kg/ha phosphorus fertilizers  level application is increase the yield of wheat crops in chancha woreda but the further conducting of the researches in different location is important for sound full recommendation
