Effect of application of phosphate to legumes on the growth and yield of the succeeding ragi crop (Eleusine coracana)
(Division of Agronomy, Agricultural College and Research Institute, Vellayani, 1964) Ittyaverah, P J; George, C M
An investigation was carried out to study the response of three common leguminous green manure crops of this State viz. Seabania speciosa, Crotalaria juncea and Crotalaria striata to different doses of P2O5 and their comparative residual effect on the succeeding ragi crop. The experiment was laid out in the farm, attached to the Agricultural College and Research Institute, Vellayani. Phosphate was applied at three levels viz. 0,20 and 40 lb. per acre. This was applied directly to the ragi crop, and also indirectly through the preceeding green manure crops. A uniform basal dose of potash (40 lb. K2O per acre) was applied directly to ragi in all the treatments.
Effect of applied nitrogen and phosphorus on the nodulation in groundnut (Arachis hypogaea L.)
(Kerala Agricultural University, 1975) Punnoose, K M; George, C M
An experiment was conducted in red loam soils of the farm attached to the Agricultural College Vellayani, with the object of studying the effect of applied nitrogen and phosphorus on the nodulation in groundnut. The levels of nitrogen were 0, 10 and 20 kg/ha and those of phosphorus 0, 25, 50, 75, and 100 kg/ha. The number and dry weight of nodules per plant observed at three stages of 2, 4, and 6, weeks after planting were studied. Application of nitrogen significantly reduced and the phosphorus application significantly increased the mean number and dry - weight of nodules at all the three stages of observation. It was also noticed that both the mean number and dry - weight of nodules have increased from the first stage of observation to the second stage and thereafter decreased in the third stage.

Effect of date of sowing and combination of nitrogen, phosphorus and potassium on the growth and yield of sea island cotton (Gossypium barbadense Linn.)

Effect of date of sowing and nitrogen fertilisation with micronutrients on the yield and quality of hybrid maize (Zea mays, L.)

Effect of date of sowing and nitrogen fertilization with micronutrients on the yield and quality of hybrid maize - deccan makka
(Kerala Agricultural University, 1975) Pushpangadan, K; George, C M
An investigation carried out at the Agricultural College Vellayani to study the effect of date of sowing and nitrogen fertilization combined with a mixture of micronutrients revealed that the most suitable date of sowing would be before the onset of the South West monsoon round about June 10 and June 20 provided there is adequate pre-monsoon showers for early agricultural operations. For a plant population of about 43, 250 per ha. the optimum level of nitrogen would be 186 kg per ha. Application of micronutrient mixture does not seem to influence the growth and yield attributes of corn.
Effect of micronutrients on paddy in a red loam soil of Kerala

Effect of nitrogen and phosphorus on the yield and quality of groundnut (Arachis hypogaea L) in the red loam soils of Kerala
(Kerala Agricultural University, 1974) Punnoose, K I; George, C M
A trial was conducted in the red loam soils of the farm attached to the College of Agriculture Vellayani, Kerala State, during the year 1967 to study the response to graded doses of nitrogen and phosphorus on the yield and Quality of groundnut variety. The data relating to the yield and quality factors were studied. Quadratic response curves were fitted to the yield data and ihe optimum as well as the economic doses of nitrogen and phosphorus were determined. There was significant positive response in yield to nitrogen and phosphorus application. The 10kg. level of nitrogen gave the highest yield. Phosphorus has progressively increased the yield with incremental doses. A combination of 10 Kg. nitrogen and 75 kg. P5O has given the maximum pod yield of 2195.24 Kg/ha. The oil content of kernel was significantly depressed by nitrogen application. But phosphorus application has resulted in a significant increase in oil content. Graded doses of nitrogen and phosphorus could markedly increase the protein content of kernel. The economic doses were found to be 12.72 kg. nitrogen and 54.04 kg. P2O3/ha.

Effect of phosphorus and molybdenum on flowering and podformation in groundnut CO POL-1
(Kerala Agricultural University, 1975) Muralidharan, A; George, C M; Sadanandan, N
Field experiment conducted at tiie Agricultural College, Vellayani with 4 levels of PaO,, and 3 levels of molybdenum revealed that i l ) Application of P2O6 @ 50 kg/ha significantly reduced the preblossom period which was delayed by higher levels of phosphorus and molybdenum. (2) P2O,s ••<(. 85 and 100 kg/ha increased the number of pegs and mature pods/plant. Molybdenum though increased the number of pegs/plant did not influence the numbsr of mature pods/plant. (3) PaO- and molybdenum at higher levels reduced the percentage of pegs developed to mature pods.
