Abstract:
A field experiment was conducted at Instructional Farm, Department of Agronomy, Rajasthan College of Agriculture, Udaipur (Rajasthan) during the rabi 2013-14. The experiment consisted combinations of two dual purpose barley varieties (RD 2715 and RD 2552), three cutting schedules (40, 50 and 60 DAS) and three fertility levels (RDF: 60 kg N+20 kg P2O5/ha, RDF+25% extra N and RDF+50% extra N). These 18 treatment combinations were evaluated under factorial randomized block design with three replications. The results revealed that comparing to variety RD 2552, RD 2715 grew taller and produced significantly higher plant height, number of total tiller, dry matter and LAI at 35 DAS, at fodder cutting and after fodder cutting different successive growth stage and at harvest. Dual purpose barley varieties did not significantly influenced on day to 50 per cent heading and maturity of crop after green fodder cutting. Variety RD 2552 recorded significantly higher grain, straw and biological yield over RD 2715. Various cutting schedules did not significantly influenced on plant height, number of total tiller, dry matter and LAI at 35 DAS. Delaying in cutting of green fodder improved plant height, number of total tillers, dry matter accumulation and LAI at harvest of green fodder. After cutting of green fodder, the plant height and dry matter accumulation at 15, 30, 45 days and at harvest were recorded the maximum when fodder cutting at 40 DAS as compare to 50 and 60 DAS. Days to 50 per cent heading was higher when crop was harvested at 40 DAS for green fodder. Green fodder was cut at 40 and 50 DAS were significantly improved the days to maturity as compare to 60 DAS after green fodder cutting. Green fodder cutting at 60 DAS produced highest green fodder yield (29.80 t ha-1), as compare to 40 DAS and 50 DAS, while grain (4.10 t ha-1), straw (7.09 t ha-1) and biological yield (11.19 t ha-1), produced significantly higher at 40 DAS over 50 DAS and 60 DAS green fodder cutting. Different fertility levels did not significantly influenced on plant height, number of total tiller, dry matter and LAI at 35 DAS. Compared to RDF and RDF + 25 per cent extra N, application of RDF + 50 per cent extra N significantly influenced on plant height, number of total tiller, dry matter and LAI at harvest of green fodder. Application of RDF + 50 per cent extra N significantly increased plant height and dry matter over RDF at 15, 30 and 45 days after green fodder cutting and at harvest. However, found at par with RDF + 25 per cent extra N. Various fertility levels did not significantly influenced on days to 50 per cent heading and maturity after green fodder cutting. Application of RDF + 50 per cent extra N significantly enhanced green fodder, grain, straw and biological yield over application of RDF and RDF + 25 per cent extra N.
