Effect of shade, organic, inorganic and biofertilizers on morphology, yield and quality of turmeric

A field experiment was conducted to study the effect of partial shade, inorganic, organic and biofertilizers on morphological parameters, yield and quality of turmeric cv. CL 147. The study was laid out in split plot design consisting of different doses of inorganic fertilizers, organic manures, biofertilizers and growth stimulants constituting to about 40 different treatment combinations. Under partially shaded conditions, the treatment combination, 100 per cent NPK + 50 per cent FYM (15 t ha⁻¹) + coir compost (10 t ha⁻¹) + Azospirillum (10 kg ha⁻¹) + phosphobacteria (10 kg ha⁻¹) + 3 per cent Panchakavya exhibited cent per cent sprouting (100.00), increased height of the plant (90.52 cm), number of leaves (19.70), leaf area (723.51cm²) and the highest estimated yield (34255kg ha⁻¹) at 180 DAP as compared to the absolute control in open conditions. Whereas, increased number of tillers (4.15) was recorded in the same treatment in open condition. Regarding the quality parameters, provision of shade improved the curcumin (5.42%), oleoresin (10.15%) and essential oil (5.60%) content in the treatment, 50 per cent FYM + coir compost + Azospirillum (10 kg ha⁻¹) + phosphobacteria (10 kg ha⁻¹) + 3 per cent Panchakavya.
