The Response of Different Soybean Varieties Yield and Yield Components to Different Reduced Irrigation Levels in District Swat of Pakistan

Abstract

A field study was conducted on clay loam soil at the Agriculture research institute, Swat during Kharif 2012. Main objective of the study was to compare the yield, yield components and harvest index of soybean using two varieties (swat 84 and malakand 96) having four replicates and four irrigation level. Mean of productive pods for I₄₀, I₆₀, I₈₀, I₁₀₀ were 1078, 1039, 1237 and 1257 respectively. The grain yield mean was obtained for V₁ and V₂ was 2969 and 3302 respectively and mean of grain yield for I₄₀, I₆₀, I₈₀, I₁₀₀ were 2724, 2963, 3317 and 3536. Mean of biological yield for I40, I60, I80 and I100 were 6042,6131, 6392, 6558 respectively.Mean harvest index 44% was recorded for V₁ and  45% for V_2. Results showed that among both the varieties V₂ performed better on irrigation four (V₂I₁₀₀) therefore, it is recommended for irrigated areas of Khyber Pakhtunkhwa, Pakistan
