ABSTRACT
The present research experiment entitled “"Effect of integrated nutrient management on morphology, physiology, yield and quality of mungbean (Vigna radiata (L.) Wilczek)”. Treatments for physiological efficiency and productivity” was conducted during Kharif season of 2012-13 at the Research Farm, Dusty Acre area, Department of Plant Physiology, JNKVV, Jabalpur (M.P). The experiment was laid out in a randomized block design replicated thrice and treatments comprised of ten mungbean treatments which were assessed for various morphophysiological traits and productivity potential.
The results revealed that among the phenological traits were effected due to treatments and indicated that 100% RDF +FYM @ 2t/ha + Rhizobium had the earliest flower initiation (34.00 days), days to 50% flowering (44.33 days) and days to pod formation (55.00 days), however 100% RDF +Vermicompost @ 1.2t/ha + Rhizobium was found to be associated with early pod initiation (48.67 days) and attained the physiological maturity at the earliest (57.67) and recorded longest maturity period (76.67 days) These traits may be utilized for the future breeding programme. Treatment 100% RDF + Vermicompost @ 1.2t/ha + Rhizobium possessed higher dry matter production in leaves (76.603 g/ m2) and total dry matter production 175.4 g/ m2, LAI (1.31 m2. days), LAD (14.68 m2days), CGR (4.99 g/m2/day), SLA (0.059), RGR (0.082), Protein (24.44%), Nitrogen, Phosphorus and Potassium (323.64, 89.7, 660.8 kg/ha) respectively, carboxylation efficiency had maximum (0.034 µmol/m2/s-1(µmolmmol-1)-1) and photosynthetic rate (7.473 µmol/m2/s). In 100% + RDF +FYM @ 2t/ha + Rizobium crude fiber was maximum (2.86) and in 50% RDF +Vermicompost @ 1.2t/ha + Rhizobium Ash %( 3.44). 75% RDF +FYM @ 2t/ha + Rhizobium the chlorophyll index (58.23 g/m2) transpiration rate (5.663 mmol/m2/s), water use efficiency (2.638 µmol/mmol) was observed to be maximum and 75% RDF + Vermicompost @ 1.2t/ha + Rhizobium quantum efficiency exhibited maximum (0.009), while stomatal conductance was maximum in 100% RDF + Rhizobium (0.278 µmol/mmol). 100% RDF + Vermicompost @ 1.2t/ha + Rhizobium resulted higher magnitudes of plant height (34.94 cm), branch number/plant (4.73), pods/plant (12.73), pod length (6.00 cm) and pod weight (2.53g/plant) which in turn had reflected in maximum seed yield (3.83 g/plant and 1736.35 kg/ha). This was followed by 100% RDF + FYM @ 2t/ha + Rhizobium as related to yield performance (3.822 g/plant and 1727.28 kg/ha) which may be the higher magnitudes of physiological parameters.
