Item Quality attributes of colocasia (Colocasia Esculentus)(Kerala Agricultural University, 1980) Asokan, P K; Hassan, M A; Neelakantan Potti, NItem Chemical characteristics of lateritic soils in the ribbon valleys and corresponding uplands of Kerala(Kerala Agricultural University, 1980) Hassan, M AA comparative study of the chemical characreristics of the upland lateritic soils and the corresponding lateritic alluvium in the ribbon-valleys of the midland regions of Kerala State was conducted. The C E C, exchangeable cations, level of organic matter, total and available nutrients were all found to be low.Item Quality characteristics of five varieties of Dioscorea alata L.(Kerala Agricultural University, 1981) Ashokan, P K; Neelakantan Potty, N; Hassan, M AItem Effect of graded doses of nitrogen, phosphorus and potassium on growth and yield of oriental pickling melon (Cucumis melo var. Conomon)(Kerala Agricultural University, 1984) Hassan, M A; Sasidhar, V K; Peter, K VA 33 factorial experiment with nitrogen (0,60, 120 kg/ha), P^ (0, 45, 90 kg/ha) and KaO (0, 45, 90 kg/ha) was laid out to find out optimum and economic levels of the above nutrients for maximising fruit yield in oriental pickling melon. Response to nitrogen was observed to be quadratic and the optimum level was calculated as 96.6 kg/ha and the economic level as 45.38 kg/ha. The P206 application produced no significant effects in melon for different characters studied. Response to K20 was linear.Item Effect of copper and zinc on the nutrition of rice plant(Kerala Agricultural University, 1983) Sasidhar, V K; Hassan, M A; Santhakumari, GItem Effect of organic sources on nitrogen availability in flooded rice soils(Kerala Agricultural University, 1989) Anilakumar, K; Johnkutty, I; Hassan, M A; Menon, P K GA study was conducted during the rabi season of 1982 to study the changes of N in the lateritic rice soil as well as in the rice plant as influenced by flooding in the presence of various organic and inorganic sources of nitrogen. The results revealed that daincha treated plots were able to liberate more nitrogen in the soil as well as in the solution than farm yard manure or azolla treated or urea alone treated plots. In general the NH4-N content in the soil showed a progressive decrease from tillering to harvest (11.13 - 1.99 ppm). The chemical kinetics of NOj-N, hydrolysable-N, non-hydrolysable N, organic carbon and total N were not influenced by the various treatments. Urea applied alone or in combination with daincha was found better for increased N uptake by the rice plant.Item Kinetics of silicon in relation to different levels of major nutrients in the lateritic flooded rice soils(Kerala Agricultural University, 1990) Anilakumar, K; Johnkutty, I; Hassan, M A; Menon, P K GItem Effect of NPK fertilizers on the availability of micronutrients in submerged laterite rice soils of Kerala(Kerala Agricultural University, 1992) Anilakumar, K; Hassan, M A; Johnkutty, I; Menon, P K GItem Intake, retention and depletion of water in different rice soils as related to their physico-chemical properties(Kerala Agricultural University, 1994) Hassan, M A; Anila Kumar, KItem Variation in evapotranspiration and crop coefficients of rice at the regional agricultural research station, Pattambi(Kerala Agricultural University, 1994) Hassan, M A; Ramachandran, V R
