Studies on growth and yield attributes of different kenaf genotypes influenced by various fertlizer levels

Abstract

The experiment was conducted during Kharif 2016 at Tamil Nadu Rice Research Institute, Aduthurai, Thanjavur for studying the effect of different fertilizers levels on kenaf genotypes. The treatments comprises are such as a. Genotypes: JRK 2011-1 (V1), JRK 2011-2 (V2), AMC 108 5 (V3) and HC 583 (V4); Fertilizer levels: Control (F1), 40:8.7:16.7 kg NPK /ha (F2), 60:13:25 kg NPK /ha (F3) and 80:17.5:33.3 kg NPK /ha (F4). The results revealed that fertilizers levels significantly influenced on plant height, basal diameter and fibre yield of kenaf genotypes compared to control. Among the different genotypes, JRK 2011-2 recorded higher plant height (313 cm), basal diameter (1.42 cm) and fibre yield (22.14 q/ha) compared to other genotypes. In case of fertilizers levels, application of 80:17.5:33.3 kg NPK /ha recorded higher plant height (340.6 cm) and basal diameter (1.50 cm) and fibre yield (23.83 q/ha) which was at par with other levels. It concluded that application of 60:13:25 kg NPK /ha for JRK 2011-2 produced higher fibre yield.
