Abstract

An experiment was conducted at college orchard, Department of Spices and Plantation Crops, Horticultural College and Research Institute, Tamil Nadu Agricultural University, Coimbatore from 2014 to 2016 to study the effect of fertigation of N and K on growth and yield of turmeric transplants. The experiment consisted of nine treatments replicated three times in a randomized block design. The results showed that the fertigation treatment with 125% levels of N and K through water soluble fertilizers recorded significantly superior growth parameters viz., plant height (142.39 cm), number of leaves (14.79), number of tillers (9.19) and leaf length (31.25 cm) at 210 days after planting and yield characters viz., yield per plant (406.27 g), yield per plot (109.76 kg/25 m2), estimated yield (43.90 t/ha) and estimated cured rhizome yield (7.96 t/ha) of turmeric transplants. On the basis of good performance on yield, fertigation with 125% levels of N and K through water soluble fertilizers can be employed for turmeric transplants.
