Effect of various nitrogen levels and varieties on forage yield and quality of ryegrass lolium multiflorum l in western uttar pradesh

Abstract

The present investigation on effect of nitrogen levels and varieties on forage yield and quality of ryegrass (Lolium multiflorum L.) in Western U.P was conducted at crop research center,Sardar Vallabhbhai Patel University of the agriculture and technology, Meerut UP during the Rabi season of 2022- 23 and 2023- 24 the treatments consist of two factors either first vector including three varieties of the Ryegrass viz Punjab Ryegrass-1, Punjab Ryegrass-2, Milky graze-3636, and in Second factor including five nitrogen levels viz:, o,50,75,100 and 125 kg ha , Where tested in factorial sandy loam texture, low in organic carbon and available nitrogen, medium in available nitrogen, medium in available phosphorus and available Potassium with near to neutral in reaction. newlineExperimental results revealed the sowing of ryegrass with milky graze-3636 recorded significantly higher values of growth attributes viz. Plant height , fresh shoot and leaves weight, leaf area index, crop growth rate and dry matter and green forage Quality parameters viz, nitrogen and crude protein content significantly increased while ADF and NDF significantly decrease with milky graze-3636 variety during both the years of experiment. The higher gross return, net return and benefit cost ration during both of the years. newlineIncreasing levels of nitrogen form 0 to 125 kg ha caused significant increase growth parameters and yield. Application of 125 kg nitrogen per hectare resulted in to maximum plant height, fresh shoot and leaves weight, leaf area index, crop growth rate and dry matter and green forage yield than lower levers of nitrogen during both the years. The quality parameters vix., nitrogen content in plant , crude protein content, cell content and ash content increased while ADF and NDF content of ryegrass decrease with increasing levels nitrogen at all cuttings during both the years of experiment. The higher gross return, net return and benefit cost ratio was recorded with the application of 125 kg nitrogen per hectare during both the years. newlineThus
