Effect of Organic Fertilizer Extract on Morphological Characteristics for Bread Wheat

Abstract

The field experiment conducted in one of the fields located in Babylon-Iraq, during the agricultural season 2020-2021. In order to study the effect of spraying different levels of organic fertilizer extract on the morphological characteristics of spikes wheat for three local cultivars of wheat. The experiment was conducted by Randomized Complete Block Design (RCBD)with split plot system and with three replications. The levels of spraying with organic compost extract were represented in the main plot and were 0, 2.5, 5 and 7.5 ml.L-1 and three cultivars IPA99, Rashid, Abu Ghraib, were represented by the subplot, and the following results were recorded: The fertilizer concentration 7.5 ml.L-1 was significantly excelled in all studied traits, the spike length and its stalk, awns length and diameter of spike, and they were respectively 13.71 cm, 19.16 cm, 7.16 cm, and 1.62 cm. As for Rashid cultivar excelled in the trait of spike and stalk, length 15.17 and 23.87 cm, respectively. While the IPA99 cultivar was excelled on the diameter of spike trait 1.61 cm, while Abu Ghraib excelled in the awns length trait with a total average 7.57 cm.
