| Abstract/Description: | The present research experiment was conducted during Kharif season of 2014-15 at the Horticultural Research Farm, Department of Horticulture, JNKVV, Jabalpur (MP). The treatments comprised of ten cowpea genotypes. The objective of the experiment was to evaluate cowpea genotypes for physiological efficiency and productivity under agro climatic conditions of kymore plateau zone, Madhya Pradesh. The investigations revealed that the genotype 2014/COPBVAR-6 out yielded other genotypes (232.74 g plant per plant) owing to its highest dry matter production (47.65 g) followed by the genotypes 2014/COPBVAR-5 and Gomti. Gomti had the highest chlorophyll index (53.9), carboxylation efficiency 0.2070 ìmolm-2s-1(mmolmmol-1)-1 and Quantum efficiency (0.0412) reflected ultimately the highest pod yield per plant. Gomti recorded the maximum quantum efficiency (0.0412), photosynthetic rate (49.66 mmolm-2s-1) and carboxylation efficiency 0.207 mmolm-2s-1(mmol m mol-1)-1. The highest water use efficiency was found in the genotype 2012/COPBVAR-2 (62.8 mmol m/mol) and mesophyll efficiency in the genotype 2012/COPBVAR-5 1897.14 molmol-1(mol m-2s-1)-1 with the lowest stomatal conductance (0.14 mol m-2s-1) and transpiration rate (0.59 mmol m-2s-1) suggesting their suitability for drought resistance may also be utilized in a breeding programme |
