Abstract:
Field experiment was conducted with an objective to increase the productivity and quality of turmeric through micro-nutrient management and variety at College of Horticulture and Forestry, Central Agricultural University, Pasighat, Arunachal Pradesh during the year 2017-18 to 2019-20 in FRBD with four replications. The soil type of the experimental field is sandy loam with pH value of 5.2 having high organic carbon (1.2%), medium in available nitrogen (315 kg N/ha), low in available phosphorus (21 kg P₂O₅/ha) and high in available potassium (360 kg K₂O/ha). Result of the three years of experimention as well as pooled mean indicated that recommended package of practices (120:50:120 kg NPK/ha) + foliar spray of IISR turmeric micronutrient @ 5g per litre at 60 and 90 days after planting recorded significantly higher number of tillers per plant, fresh weight of clump, rhizome yield as compared to recommended package of practices. However, the differences in plant height, days to 80% maturity and dry recovery between the treatments were not significant. Among the three varieties, the variety NDH 98 recorded significantly highest number of tillers, fresh weight of clump and rhizome yield as compared to IISR Pragati and Megha Turmeric-1. Though, the maximum plant height and maturity to 80% were recorded with the vareity NDH 98 but it remained at par to Megha- Turmeric-1. However, significantly highest dry recovery (%) of turmeric was observed with Megha-Turmeric-1. Significantly higher curcumin content was associated with the application of recommended package of practice plus foliar spray of IISR micronutrient in the variety Megha-Turmeric-1.
