Item Effect of liming on available nutrients and yield of paddy in the acid soils of Kuttanad(Kerala Agricultural University, 1974) Kabeerathumma, S; Money, N SThe significance of lime application to the acid paddy soils of Kuttanad with respect to enhancing available nutrients and yield of paddy varieties was studied. Lime application apart from correction of harmful effects of acidity, increases the availability of essential nutrients and provides better conditions for their assimilation thereby resulting in enhanced yields of rice. The study has also brought out the inherent difference in the nature of acidity between Kari and Karapadom soils and in their capacity for utilisation of applied fertilizers.Item Availbale zinc, copper, iron and manganese status of the acid rice soils of Kuttanad, Kerala state(Kerala Agricultural University, 1975) Aiyer, R S; Rajagopal, C K; Money, N SDetermination of available zinc, copper, iron and exchangeable manganese in the [Cari, Karapadom and Kayal soils of Kuttanad region, Kerala State, revealed that all the three soil types are highly deficient in available copper (90%). Available zinc was deficient in 50% of the Kayal soils studied. High amounts of available iron in the Kari soils suggest the possibility of iron toxicity to rice in these soils. Significant and positive correlations existed between available copper on the one hand and organic carbon (r= + 0.400) and CEC (r= + 0.566! on the other. Available iron was significantly and positively correlated with organic carbon (r= +0689) and CEC (r= -f 0.566) and significantly and negatively correlated with pi! (r= - 0.425) and exchangeable Ca + Mg (r= - 0.408). The results warrant application of copper in all the three types of Kuttanad soils and of zinc in the Kayal soils.Item Response of rice (variety 1R-8) to zinc as affected by levels of phosphatic fertilisers(Kerala Agricultural University, 1975) Prabha, R; Aiyer, R S; Money, N SAn attempt was made to produce phosphorus induced zinc deficiency in rice plants (var. IR-8) under pot culture conditions with 18 treatments, being the combinations of 6 levels of P and 3 levels of Zn. Yield of grain and straw were significantly increased by the application of both zinc and phosphorus. At higher doses of Phosphorus the yield of grain decreased slightly. The optimum combination of P and Zn was found to be 72.5 kg P2 Oa/ha and 25 kg ZnSOJha. The study has revealed that for the proper uptake and utilisation of zinc especially when the soil is poor in available zinc the P levels have to be kept low. High levels of P may lead to zinc deficiency. Such deficiency can be corrected by tha application of zinc in the soil.Item Studies on some chemical and mechanical properties of salt-affected rice soils of Kerala(Kerala Agricultural University, 1972) Nair, P G; Money, N SItem Studies on the influence of liming on the growth and yield of rice in an acid peat soil (Kari soil) of Kerala(Kerala Agricultural University, 1971) Sukumaran, K M; Balakrishna kurup, T K; Money, N SItem Studies on the detection of adulteration of bone-meal during routine analysis(Kerala Agricultural University, Vellanikara, 1968) Ramasubramonian, P R; Money, N SItem Influence of calcium and magnesium in increasing the efficiency of fertilisers for rice in Kerala for rice in Kerala(Kerala Agricultural University, Vellanikara, 1964) Thomas, Varghese; Money, N SItem Species of algae found in acid sulphur springs of Kerala(Kerala Agricultural University, Vellanikara, 1963) Money, N S; John, K CItem Studies on the soils of Kuttanad - part II-microbiological nitrogen transformations in acid peat soils of Kuttanad(Kerala Agricultural University, Vellanikara, 1961) Money, N S
