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 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 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 Influence of salinity on the germination and growth characteristics of rice(Division of Agricultural Chemistry, Agricultural College and Research Institute, Vellayani, 1963) Remani, B; Money, N SA study was made of the influence of salinity on the germination, growth and yield of different varieties of rice. Germination was studied in the laboratory for five varieties using nine salts at different concentrations. Growth and yield characteristics were observed for two varieties in a pot culture experiment by flooding the soil with sea water for twenty four hours at different stages in the growth period of the plants. The percentage germination was reduced in all the varieties with increase in the concentration of the salt. For the same concentration the adverse effects of salts on germination increased in the order ammonium chloride ammonium sulphate < sodium chloride < sodium sulphate < potassium chloride < potassium sulphate < magnesium sulphate < calcium chloride. Chlorides were generally more toxic than sulphates. Among the cations, ammonium and potassium were the least toxic, sodium and magnesium were more so, while calcium was the most injurious.Item Physico-chemical and microbial studies on some 'Kari' soils of Kerala(Division of Agricultural Chemistry, Agricultural College and Research Institute, Vellayani, 1964) Sukumara Pillai, V; Money, N SA study has been made of the morphological, physiochemical and microbiological properties of four typical profiles from the Kari areas of Vaikom Taluk. The soils are black to dark grey in colour, and can be texturally classed as clays or clay-loams. There is an irregular distribution of the soil separates in the profile , suggesting their formation by deposition and sedimentation.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 Species of algae found in acid sulphur springs of Kerala(Kerala Agricultural University, Vellanikara, 1963) Money, N S; John, K CItem Studies on a manure supplement containing secondary and trace elements prepared from sea water (Sagar) on the growth, yield, quality and absorption of nutrients by rice(Division of Agricultural Chemistry, College of Agriculture, Vellayani, 1975) Chinnamma, N P; Money, N SA field experiment was conducted to assess the effect of application of Sagar, a manure supplement prepared from the sea water on the growth, yield and quality of rice and absorption of nutrients from soil. The result obtained are summarised below. 1) Application of NPK increased significantly all the growth characters and these characters were increased steadily with increase in the levels of NPK. Sagar application increased considerably the number of tillers and the number of productive tillers per plant.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 detection of adulteration of bone-meal during routine analysis(Kerala Agricultural University, Vellanikara, 1968) Ramasubramonian, P R; Money, N SItem Studies on the fractionation of soil phosphorus and the absorption and retention of ammonium nitrogen in kerala soils(Division of agricultural Chemistry, Agricultural College & Research institute Vellayani, Trivandrum, 1963) Narayanan Nambiar, P K; Money, N SA study was undertaken with the object of finding o u t t h e retention of ammonium nitrogen in different soils of Kerala when applied in the form of ammonium sulphate and leached after one day or one week contact. Eight soils differing in texture were taken and treated with ammonium sulphate solution of three different concentrations, viz., 52.50, 10500 and 21000 ,ug.N/lOO g. of soil under the laboratory conditions. The unadsorbed nitrogen was found out by estimating nitrogen in the supernatent liquid. The ammonium nitrogen retained by the soil was estimated after leaching the soil with known volume of water. The statistical evaluation of the relation between the textural separates and the ammonium nitrogen retained was also made.Item 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 soils of Kuttanad - part II-microbiological nitrogen transformations in acid peat soils of Kuttanad(Kerala Agricultural University, Vellanikara, 1961) Money, N S
