    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 nitrogen and phosphorus on asiriya mwitunde groundnut in Kerala
    (Kerala Agricultural University, 1975) Jayadevan, R; Sreedharan, C
    An experiment was conducted to assess the high fertilizer responsiveness of Asiriya Mwitunde, a groundnut variety introduced from Tanganiyaka in respect of N and P under the soil and climatic conditions of Kerala. The various growth characters such as height, leaf and haulm production were significantly increased by 30 kg N/ha. Application of P upto 100 kg/ha increased significantly the yield attributes such as weight of kernels, test weight, shelling percentage in this variety. Pod yield was significantly increased by 20 kg N and 75 kg P giving a per hectare yield of about 2969 kg/ha under the agro-climatic conditions of Kerala.

    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 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.

    Respiratory and enzymatic changes in the sclerotial root rot of groundnut
    (Kerala Agricultural University, 1977) Anandavally Amma, P; Shanmugam, N; Chandrasekharan Nair, M
    Infection of groundnut hypocotyl region by Schrotium rolfsii was found to augment the respiratory rate of the host tissue. The respiratory rate reached the maximum during the symptom development stage and at this stage the activity of all the important terminal oxidative enzymes were also found to be enhanced. The results are discussed as proof of the role of increased oxidative enzyme activity in enhancing the respiratory rate of infected groundnut plants.

    TG-3, a variety of groundnut suitable for cultivation under partial shade in coconut gardens
    (Kerala Agricultural University, 1991) Sreekumar, S G; Gopinathan Nair, V; Saraswathy, P
    Comparative evaluation of eight varieties of groundnut was conducted at the Regional Agricultural Research Station of NARP (SR), College of Agriculture, Vellayani for three years during 1984, 1986 and 1987 kharif seasons. The field experiment ( 8 x 3 RBD) was conducted at the interspaces of coconut garden under partial shade for identifying a suitable groundnut variety with high yield and shade tolerance. The pooled analysis of the data for three years revealed that the variety TG 3 was consistently superior in dry pod yield. Therefore, it was recommended for inclusion in the package of practices recommendations of the Kerala Agricultural University as a suitable variety for cultivation as intercrop in coconut garden under partially shaded conditions.
