Item Influence of nitrogen and lime on the k/(Ca + Mg) ratio of dinanath grass (Pennisetum pedicellatum Trin.)(Kerala Agricultural University, 1980) Abraham, C T; Sreedharan, C; Raghavan Pillai, GItem Effect of nitrogen and lime on the yield attributes and yield of dinanath grass (Pennisetum pedicallatum Trin.)(Kerala Agricultural University, 1980) Abraham, C T; Raghavan Pillai, G; Sreedharan, CItem Fodder production potential of sweet potato (Ipomoea Batatas)(Kerala Agricultural University, 1980) Raghavan Pillai, G; Kamalam Joseph; Sreedharan, CItem Effect of phosphorus and lime on the growth attributes and yield Stylosanthes gracilis Swartz(Kerala Agricultural University, 1980) Mariyappan, H; Chandrasekharan, P; Raghavan Pillai, GA field experiment conducted to study the effect of graded doses of phosphorus (0,40, 80, 120 and 160 kg/ha ) on the growth attributes, green and dry matter yields of Stylosanthes gracilis Swartz with two levels of lime [0 and 500 kg/ha] in the red loam soils of the Instructional farm, College of Agriculture. Vellayani has shown that growth attribuies like plant height, number of leaves, number of branches and leaf/stem ratio were not influenced by the application of graded doses of phosphorus except lime which increased the leaf number significantly. Phosphorus at the rate of 120 kg/ha recorded the maximum green matteryteld and dry matter production. Although lime level at 500 kg/ha failed to produce significant increase in green matter and dry matter yields, a positive trend was noticed by lime application.Item Fodder production potential of five cultivars of bajra (Pennisetum Typhoides.Stapf) in coconut garden lands of Kerala(Kerala Agricultural University, 1981) Raghavan Pillai, G; Purushothaman Nair, N; Sreedharan, CItem Crude protein and crude fibre content of fodder grasses as influenced by legume intercropping and phosphorus application(Kerala Agricultural University, 1982) Chandini, S; Raghavan Pillai, G; Sreedharan, CItem Fodder production potential of grass legume mixtures as influenced by phosphorus levels(Kerala Agricultural University, 1985) Chandini, S; Raghavan Pillai, G; Sreedharan, CItem Nutrient removal by rice crop and weeds(Kerala Agricultural University, 1987) Lakshmi, S; Nair, K P M; Raghavan Pillai, G; Muraleedharan Nair, VItem Effect of phosphorus, lime and cutting interval on green fodder yield, nodulation and protein enrichment of Stylosanthes gracilis and nitrogen in soil(Kerala Agricultural University, 1987) Mariyappan, H; Chandrasekharan, P; Raghavan Pillai, GAn experiment was conducted at the Instructional Farm, College of Agriculture, Vellayani, Kerala during 1977-78 to study the effect of phosphorus levels, lime and cutting intervals on green fodder yield, protein enrichment and nodulation of Stylosanthes gracilis and nitrogen build up in the soil. The treatments constituted five levels of phosphorus viz., 0,40, 80, 120 and 160 kg P205/ha, two levels of lime viz., 0 and 500 kg CaO/ha and two intervals of cutting viz., 30 days and 45 days. The green fodder yield, protein content and protein yield were found to increase progressively upto 120 kg P205/ha. The combination of phosphorus and lime had significant influence in increasing the green fodder yield and protein content. Cutting interval of 45 days recorded more green fodder yield and the combination of 120 kg phosphorus per hectare with 30 days interval of cutting recorded the maximum protein content. Nodule number and weight were found to increase progressively upto 120kg P205/ha. but lime and cutting interval had no significant influence. An increase of 7.3% of total nitrogen content of soil with increase in the levels of phosphorus was observed. Phosphorus and lime together contributed for the increase in the available nitrogen.Item Cutting management in subabul(Kerala Agricultural University, 1990) Meera Bai, M; Lakshmi, S; Raghavan Pillai, G
