Item Effect of phosphorus and lime application on rice variety-I. R. 8(Kerala Agricultural University, 1977) Suseelan, P; George, C M; Sreedharan, CItem Studies on the effect of graded doses of phosphorus in conjunction with lime on growth , yield & phoperous uptake in rice (Oryza sativa Linn.) Var. IR B.(Division of Agronomy, Agricultural college & reseach institute Vellayani, Trivandrum, 1969) Suseelan, P; George, C MItem Studies on the uptake pattern of phosphorus by rice under graded doses of phosphorus in conjunction with lime(Kerala Agricultural University, 1978) Suseelan, P; George, C M; Sreedharan, CAn experiment was laid out in the sandy clay loam soils of the Agricultural College, Vellayani, Kerala during the first crop (Virippu) season of 1968 to study the uptake pattern of phosphorus by rice under graded doses of phosphorus in conjunction with lime using the rice variety I.R.8. The treatments consisted of 4 levels of phosphorus (0, 50, 100 and 150 kg P205/ha, respectively) and two levels of lime (0 and 3273 kg slaked lime/ha, respectively) laid out in randomised block design replicated four times. There was significant increase, in the uptake of phosphorus by the plant with increasing levels of phosphorus whether applied alone or in conjunction with lime. The pattern of phosphorus absorption showed an increasing trend upto the primordia initiation stage, followed by a gradual depression thereafter. Application of lime has favourably influenced the uptake of phosphorus at all stages of growth.
