Effect of Tillage Systems and Phosphate Fertilizer Levels in The Growth and Yield of Wheat (Triticum aestivum L.) in Al-Shurqat Jazeera Gypsiferous Soil

Abstract

Field experiments were conducted during winter season of 2013 – 2014 at al-Shurqat Jazeera location to study the effect of tillage systems and phosphate fertilizer levels on growth component and yield of wheat (Triticum aestivum L.) in gypsiferous soil. The experiments were conducted with split spot according to Randomized Complete Block Design (RCBD) with three replications for both tillage system (CT-Conventional tillage and RT-Reduced tillage). Phosphorus was applied in six levels( 0,20, 40 ,60, 80& 100 kg P. ha-1) with symbols P0, P1, P2,P3,P4 and P5 as triple super phosphate (21%P). The total number of plots were 6 x 2 x 3 = 36 experimental units. Some of growth and yield parameters were studied (plant height, spike number , spike Weight, grains yield and straw yield). Data obtained in this investigation showed significant increased in all parameters for both tillage systems. Results refer to significant increasein reduced tillage system in comparison with Conventional tillage system in the growth parameters and yield components.
