YIELD AND NODULATION OF FENUGREEK TRIGONELLA FOENUMGRAECUM AS INFLUENCED BY GROWTH REGULATORS AND VERMI-WASH

Abstract

A field study was conducted during r abi season of 2008-09 at Sardarkrushinagar to find out optimum level of suitable growth regulator for higher yield of fenugreek. The experiment consisting of ten treatments, viz., NAA (10, 20 and 30 ppm) Ethephon (50, 100 and 150 ppm) vermi-wash (1, 2 and 3 lit. ha-1) and water spray was laid in simple RBD with three replications. The result revealed that highest number of nodules /plant and their dry weight a 60 DAS as well as seed , straw and biological yield were recorded with foliar spray of NAA @ 30 ppm being at par with Ethephon @ 150 ppm and NAA @ 20 ppm which were significantly higher over rest of the treatments but initial and final plant population as well as number of effective nodules dry weight of nodules /plant were not significantly influenced with varying levels of growth regulators. Water spray treatment recorded significantly lower values of number of effective nodules and their dry weight per plant at 40 and 60 DAS as well as seed, straw and biological yields. Thus, it is inferred that foliar spray of NAA @ 30 ppm, Ethephon @ 150 ppm and NAA @ 20 ppm has been found to be better for nodulation and higher yield of fenugreek
