Effect of spraying Growth Regulator (Pix) and Micronutrients in Yield Components of Genotypes Cotton (Gossypium hirsutum L .)

Abstract

A field experimental study performed during 2009 Season in the field crop research college of Agriculture - Tikrit University . Randomized completely Block design in asiplit plot system with three replication were used , including application treatments ( growth regulator Micronutrients , growth regulators plus micronutrients ) as sub - plot and genotypes ( W888 , Marsoomi 4 , and Nazley 87 ) as amain plots. Results showed superiority Nazley 87 in boll number plant and seed cotton yield ( g plant ) . Spraying micronutrients increasing boll number plant and seed cotton yield even used alone or mixed with growth regulator , improving seed cotton yield more obviously in using micronutried with growth regulator and most obviously in using alone that gave ( 21.26 ) boll plant and ( 60.86 ) g plant seed cotton besides improving other yield components , therefore Spray micronutrients 2kg Dunum regarded adequate for increasing production seed cotton yield
