Description ABSTRACT
The present research experiment entitled “Physiological investigation on refinement of fertility schedule for maximizing growth, productivity and quality of Niger [Guizotia abyssinica (L.f.) Cass.] ” was conducted with ten treatments with different fertility levels T1 - 20:00:00 (N:P:K), T2 - 20:10:10 (N:P:K), T3 - 30:20:10 (N:P:K), T4 - 40:30:20 (N:P:K), T5 - 60:20:10 (N:P:K), T6 - 60:40:20 (N:P:K), T7 - RDF 40:20:10 (N:P:K), T8 - 75% RDF+2t FYM/ha, T9 - RDF+1t FYM/ha and T10 - Control in RBD design with three replication, at the Research Farm of Project Coordinating Unit of Sesame and Niger, (ICAR), JNKVV, Jabalpur (MP) during the kharif season of 2013-2014.
The results revealed that the phenological traits indicated that T6 (60:40:20 N:P:K kg/ha), had the earliest bud initiation (30.33 days), flower initiation (41.00 days) and days to 50 % flowering (46.00), reproductive phase (85.66 days), (106.66 days) attained the physical maturity at the earliest. Treatment (60:40:20 N:P:K kg/ha) possessed LAI (2.46), LAD (45.44 cm2days), CGR (3.06 g/cm2/day), RGR (0.0259 g/g/day), quantum efficiency (0.0548 µmol/m²/s-1), water use efficiency (7.97 µmol/mmol) and mesophyll efficiency (827.57 µmol/mmol), photosynthetic rate (55.3 µmol/m2/s), carboxylation efficiency (0.2349 mmol/m2/s-1(mmolmol-1)-1 chlorophyll index (50.9 g/m2) and transpiration rate (6.93 mmol/m2/s). While SLA was maximum in T5 @ 60:20:10 NPK kg/ha (0.0779 cm2/g)
Application of varying fertility levels resulted in a higher magnitude with plant height (116.2 cm), number of capitule/plant (66), number of seeds/capitule (46.06), length of effective nodes/plant (68.53 cm) and number of nodes/plant (8.73), weight of capitula (0.339 g) which in turn had reflected in highest grain yield (703 kg/ha). The result revealed that higher magnitudes Protein (%) (21.56) and oil % (40.06), seed oil yield kg/ha (279). However the trail can be conducted in larger plot size for future recommendations.
