Performance of kenaf (Hibiscus cannabinus L) genotypes under varying fertilizer levels in rainfed agro-ecosystem of north coastal Andhra Pradesh

Abstract

Mesta, one of the important fibre crop grown under rainfed conditions with diverse soil types. The present study was conducted to assess the performance of genotypes suitable for the srikakulam and vizianagarm districts of Andhra Pradesh. Therefore, an experiment was conducted under AINP on Jute and Allied Fibre at Agricultural Research Station, Amadalavalasa, ANGRAU. Results indicated that, significant effect of different NPK levels on the growth and yield of new kenaf genotype JRK-2016-5 compared with two check varieties viz., AMC 108 and HC 583. The highest fibre and stick yields recorded with combination dose of 60:30:30 NPK kg ha^-1 by JRK 2016-5. However, highest plant height (302.9 cm) and stick yield were recorded with application of 80:40:40 NPK kg ha^-1, but basal diameter (21.3 mm) and fibre yield recorded with application of 60:30:30 NPK kg ha^-1 toJRK-2016-5 genotype. Economic analysis suggested the best performance of JRK-2016-5 with application of 60:30:30 NPK kg ha^-1. The present findings suggested the profitable prospect of nutrient requirement for growth and higher fibre yield of kenaf genotype.
