ESTIMATION OF YIELD STABILITY AND VARIETAL SCREENING IN COTTON-SOYBEAN INTERCROPPING SYSTEM

Abstract

Compared to growing them separately as sole crops, intercropping cotton and soybeans can increase yield stability, profitability, and productivity. On the stability of yields in cotton-soybean intercropping systems, however, there is less data. The intention behind this The goal of the study is to assess crop output and identify the best genotype pairings for intercropping between soybeans and cotton. Two distinct genotypes of cotton and two genotypes of soybeans were used in field experiments utilizing a split-plot design under RCBD with three replications, in both solo and intercropping patterns. Plant height (cm), the number of nodes per plant, the number of monopodial branches, the hundred seed weight (g), the seed weight (g) per plant, the g of seed cotton yield (per plant), and the number of cotton sympodial branches were recorded. Plant height (cm), number of pods per plant, fresh and dry plant weight (g), leaf area (cm2), number of seeds per pod, and hundred seed weight (g) are the characteristics that were determined for soybeans. Treatment changes were quantified using ANOVA, and associations between disparate features were found using correlation analysis. The study found significant differences in key traits between soybean and cotton genotypes and treatments at D.G. Khan. SCYPP positively correlated with BoPP, NON, PH, and SWP in cotton, while YPP significantly correlated with HSW, PH, DPW, and NPP in soybean. MNH- 1020 and NARC-21 were recommended for maximum yield under intercropping. The results will be useful in formulating suggestions for the ideal crop spacing and variety matching when intercropping soybeans and cotton.
