Item New pre-emergence chemicals for weed control in flooded rice(Kerala Agricultural University, 1978) Nair, R R; Kuriakose, T F; Saifuddin, NItem Nitrogen and carbohydrate status and their accumulation in the plant-parts of early rice culture, 24-20(Kerala Agricultural University, 1973) Kuriakose, T F; George, C MItem Response of groundnut to phosphorus and potassium under different water management practices(Kerala Agricultural University, 1983) Jose Mathew; Nair, K P M; Kuriakose, T FA field experiment conducted in the sandy loam soil of the Agronomic Research Station, Chalakudy, to study the effect of different irrigation schedules (0.3, 0.6 and 0.9 IW/CPE ratios) and graded doses of phosphorus and potassium 25,50 and 75 kg P205 and K20 per ha respectively) on the growth attributes, yield and yield characters has shown that growth attributes like plant height, number of branches per plant, number of leaves per plant and LAI were favourably influenced by irrigation and application of potassium. Yield characters like number and weight of mature pods per plant, 1 00 pod weight and 1 00 kerne! weight were higher at higher levels of irrigation, phosphorus and potassium. Highest yield was recorded when irrigations were scheduled at 0 9 IW/CPE ratio (irrigating once in 12 days) and 50 kg P205 and 75 kg KaO per ha was found to be sufficient for better yields.Item Studies on an early rice culture 24-20. dry matter production and its distribution among plant parts(Kerala Agricultural University, 1973) Kuriakose, T F; George, C MItem Studies on the isolation of superior clones in guinea grass - Panicum maximum(Kerala Agricultural University, 1974) Raghavan Pillai, G; Kuriakose, T F; Sadanandan, NItem Yield potential and nitrogen response of early rice culture, 24-20(Kerala Agricultural University, 1974) Kuriakose, T F; George, C MThe yield potential, nitrogen response and the anicillary characteristics of the early rice culture, 24-20 that matured in 75-80 days under Vellayani conditions were studied in relation to four levels of nitrogen fertilization. The maximum grain yield of 5559 Kg. per hectare was obtained at 90 Kg nitrogen level. The maximum productivity of the early culture was 68.8 Kg. per hectare per day indicating that a a moderately higher grain yield could be obtained with varieties of 80 day duration. The optimum nitrogen requirement was found to be 82.35 Kg. per hectare. The important role of very early varieties in the context of limited availability < - f nitrogenous fertilizers is also indicated.
