Study of physiological growth indices of chickpea in chickpea (Cicer arietinum) + mustard (Brassica juncea) intercropping system under different weed management practices

The field experiments were carried out during rabi season of 2009–10 and 2010–11 at the Research Farm of Sher-e-Kashmir University of Agricultural Sciences and Technology of Jammu, Chatha to assess the physiological growth indices in chickpea+mustard intercropping system under different weed management practices. The significant superiority of replacement series treatment for leaf area index of chickpea over additive series treatment was noticed. The crop of sole chickpea was followed by replacement and additive series treatments in recording highest dry matter, crop growth rate and net assimilation rate values. Sole stand of chickpea recorded numerically higher relative growth rate (RGR) followed by replacement and additive series treatments. Weed free treatment recorded numerically the highest crop growth rate (CGR) and net assimilation rate (NAR) of chickpea at all the stages of observation. Sole chickpea produced higher yield as compared to chickpea+mustard when grown in additive and replacement series in the respective order.
