Effect of artificial induction of flowering in pineapple
(Kerala Agricultural University, 1980) Balakrishnan, S; Nayar, N K; Valsamma Mathew
A study was undertaken at the Pineapple Research Centre, Vellanikkara during 1976—78 ye^irs to 3Ssess the influence of growth regulator 100 ppm ethrel solution containing 2% urea and 0,04# calciu.n carbonate in inducing flowering of pineapple plants raised from suckers and crowns. The crowns were not found to be as vigorous as suckers in growth chaiacteristics. Crowns the age group 17 to 20 months can be induced to flower earlier and uniformly. For getting better fruit weight, it is preferable to apply growth regulator on 20 month old crowns.
Effect of nitrogen nutrition on quality and storage behaviour of pineapple
(Kerala Agricultural University, 1980) Balakrishnan, S; Aravindakshan, M; Marykutty, K C; Valsamma Mathew
In studies on the effect of different levels of nitrogen nutrition on fruit quality and storage behaviour of pineapple, it was found that at harvest, the maximum reducing sugars, brix to acid ratio and sugar to acid ratio were registered at lowest level of nitrogen at 8g/plant As the level of nitrogen was increased to 12g/plant, total sugars increased, but there was a decrease as the level was further increased to 16g/plant. Acidity and TSS showed an increasing trend with increasing levels of nitrogen. During cold storage, higher levels of nitrogen recorded a decrease in reducing sugars. Maximum increase in acidity was recorded by the lowest level of nitrogen under both storage conditions. Increase in nitrogen level upto 12g per plant was found to have a favourable influence on total sugars in both open and cold storage conditions. Better retention of brix to acid ratio in cold storage and to reducing sugars in open storage was observed when the nitrogen dose was increased to 16g/plant.
Effect of size of suckers on growth and yield in pineapple (Ananas Comosus. Merr.) cv. Kew
(Kerala Agricultural University, 1981) Balakrishnan, S; Nayar, N K; Valsamma Mathew
Studies carried out at the Pineapple Research Centre, Kerala Agricultural University, Vellanikkara during 1976-78 on the effect of different sizes of suckers on growth and yield in pineapple variety 'Kew' revealed that the productivity of the crop is not influenced by the size of suckers used for planting.
Intercropping in rainfed banana, musa (Aab) 'palayankodan'
(Kerala Agricultural University, 1987) Valsamma Mathew; Aravindakshan, M; Parameswaran, N K
None of the intercrops reduced the vegetative growth and yield of banana. However, the returns from intercrops like cowpea, ginger, colocasia and tapioca were not sufficiently high to compensate for the extra cost on the fertilizers and planting materials. The result suggested that intercropping of banana with turmeric or yam would prove profitable to the banana growers of Kerala under rainfed conditions.
Nitrogen nutrition in rainfed banana cv. Palayankodan
(Department of Horticulture, College of Horticulture, Vellanikkara, 1980) Valsamma Mathew; Aravindakshan, M
The present investigations was carried out in the Department of Pomology, College of Horticulture, Vellanikkara from 1979 to 1980. The object of the study was to find out the effect of different levels of nitrogen on growth, yield and quality of fruits uptake and distribution of nutrients at different phases of growth and development and also to assess
