Effect of Treflan Herbicide and Phosphorus Levelson Weeds and Chick Pea Yield

Abstract

A field experiment was conducted in Research Farm of Agriculture College, Duhok University during growing season of 2017 in tow sowing dates (20/2 and 10/3/1917) to investigate four levels of Treflan herbicide (0, 1.200, 2.400, and 3.200) L ha -1, ) and four phosphorous level ((0, 140, 180 and 220) Kg P 2 O 5 ha -1 . on growth of weed, yield and yield components of chickpea. Treatments arranged in factorial experiment based on Randomized Complete Block Design (RCBD) with three replications.The results revealed that treflan and phosphorous levels showed considerable reduction on number and dry weight of broad narrow leaved weeds, and significant effect on yield and yield components of chickpea were recorded under interaction (H 3 P 3 D 1 ) and produced the highest values (1.5, 76.4, 34.3 g, 6.9 g and 58.3cm) for number of seeds pod -1 , seeds plant -1 , 100-grain weight, grain yield plant and height of the lowest pod.
