Effect of Tillage systems and NPK Fertilizer on Growth and Yield of Chickpea (Cicer arietnum) under Sulaimani Conditions

Abstract

This study was conducted during 2017 season at Bakrajo Agriculture Research Station, College of Agricultural sciences, University of Sulaimani, using split plot design the main plots conducted in Randomized Completely Block Design (RCBD) with three replicates to study the effect of three tillage systems using (Mould board plow followed by Cultivator one pass, Disk plow followed by Cultivator one pass and Cultivating one pass) and NPK fertilizer levels on growth, yield and yield components of chickpea. The three tillage systems were implemented in the main plots, three NPK fertilizer levels (0, 40 and 80) kg NPK/ha from NPK complex (15-15-15) source, were implemented in the subplot. Comparisons between means were carried out by the least significant difference (L.S.D) at 1 % and 5 % level of significance. The results of this investigation confirm that plowing with mould board followed by Cultivator recorded the maximum values for all of the studied characters which indicate the effectiveness of this system compared to disc plow followed by Cultivator and Cultivator one pass.The application 80 Kg NPK/ha was found to be the best level for this crop.
