Evaluation of Several Wheat Cultivars in Respond to Different Types of Fertilizers Including Bio-Fertilizer Under Rainfed Conditions

Abstract

The research was conducted during 2018-2019 growing season to study the growth and yield of various wheat cultivars under various methods of fertilizers application including bio-fertilizer under rainfed conditions of two different isohyets conditions. Randomized complete block design was applied with four replications. Potential grain yield is highly affected by the number of reproductive tillers; differences in final grain yield were highly and positively correlated to the number of tillers (r= 0.54**) and above ground biomass (r= 0.68**). The grain yield was about three times higher in Rikava location (3.19/1.01 t.ha-1). Both of Cihan and Adana99 wheat significantly produced higher grain yield (2.44 and 2.43 t.ha-1 respectively) followed by Tammoze and Italy, the Criso durum wheat was the inferior with only 1.65 t.ha-1 grain yield. DAP fertilizer (2.58 t.ha-1) was the best fertilizer treatment followed by YARA and BIO and all treatments were significantly higher than the check unit which produced only 1.7 t.ha-1. The interaction of Adana99 with DAP (2.79 t.ha-1) and Cihan with DAP (2.71 t.ha-1) recorded highest grain yield; these two cultivars with BIO fertilizer produced significant grain yield and each gave (2.5 t.ha-1). Financial analysis revealed the superiority of both Anana99 and Cihan cultivars with DAP fertilizer followed by BIO fertilizer as they contributed positively with the highest final revenue.

Evaluation of Herbicides Pallas and Limitless in Controlling the Narrow and Broad Leave Weeds Within Wheat Crop Fields and Their Effect on Grain Yield and It's Components

“…Urea with 46% nitrogen was used as the fertilizer, and it was given in three batches during the stages of planting, tillering, and stem elongation at a rate of 200 kg ha-1. Contrarily, a plot of land received 120 kg of triple super phosphate fertilizer (46% P2O5) before the soil started to soften (11). The experimental units were irrigated whenever needed, and crop service operations were carried out according to the recommendations followed.…”

Determination the Wheat Weight and Volume: Mathematical Approach

“…Finally; the 1000-kernal weight was 28.20 [16], 33.56 [14], 34.60 [21] , 34.70 [19], 35.10 [15] , 35.80 [22], 38.00 [18], 39.60 [23], 42,10 [24] , and 43.89 [25], for the Abu-Ghraib3 varieties. The grain weights were assigned to the same verity under different conditions [26] .Another study revealed that the 1000kernel weight was 33.5 [16]. Three other varieties showed different 1000-kernel weights, Rasheed 41.61, Bohooth 22 38.20; and Bohooth was, 35.83 [27].…”
