Abstract
The present investigation “Effect of organic and inorganic fertilizer on physiology of growth productivity and quality of Niger [Guizotia abyssinica (L.f.) Cass.]” under taken at Research Farm of Project Coordinating Unit of Sesame and Niger, (ICAR), JNKVV, Jabalpur (M.P.) during the kharif season of 2013-2014. 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 the phenological traits were effected due to treatments and indicated that 100% RDF +FYM @ 4 t/ha had the earliest bud initiation (30.66 days), flower initiation (41.00 days), days to 50% flowering (48.33 days), days to completion of flowering (66.33 days), days to physiological maturity (83.66 days) and days to physical maturity (104.66 days). These traits may be utilized in a breeding programme. Treatment 100% RDF + FYM @ 4 t/ha possessed LAI (5.616), LAD (84.247 cm2days), CGR (20.014 g/cm2/day), RGR (0.046 g/g/day) SLA (28.779 cm2/g), SLW (0.08009 cm2/g), quantum efficiency (0.055), water use efficiency (14.95 µmol/mmol), mesophyll efficiency (783.89 µmol/mmol), photosynthetic rate (56.29 µmol/m2/s), carboxylation efficiency (0.246 mmol/m2/s-1(m molmol -1) -1, chlorophyll index (52.08 g/m2), air temperature (32.08 0C), canopy temperature (30.89 0C) and control (no fertilizer) transpiration rate (6.95 mmol/m2/s) may be utilized in a breeding programme for mentioned traits.
100% RDF + FYM @ 4 t/ha resulted higher magnitudes of plant height (114.6 cm), branch number/plant (9.13), nodes/plant (7.80), effective node length (61.4 cm), no. of capitula (66.4), no. of seeds/capitula (64.11), capitula weight (0.344 g/plant), 1000 seed weight (8.35 g) which in turn had reflected in maximum seed yield (704.00 kg/ha). This was followed by 100% RDF + Vermicompost @ 2t/ha as related to yield performance (695.00 kg/ha) which may be the higher magnitudes of physiological parameters.
100% RDF + FYM @ 4 t/ha resulted higher magnitudes. Protein (%) (22.75) and oil % (40.18), seed oil yield kg/ha (283).
