    Fruit set, fruit development and fruit drop in nutmeg (Myristica Fragrans Houtt.)
    (Kerala Agricultural University, 1981) Nazeem, P A; Sivaraman Nair, P C
    Studies on fruit set, development and fruit drop in nutmeg (Myristica fragrans Houtt.) conducted in Kerala, India have indicated that the fruit set was only 33.7 per cent while the post-set fruit drop was 74.4 per cent. The ultimate harvested yield accounted to only about 8.2 percent of the total flower production. Therefore, the best method to increase fruit production is to increase the set and to lower the fruit drop. Hand pollination increased the set by about 2.5 times as compared to the natural set. The fruits showed a sigmoid growth pattern and took seven to eight months to attain maturity Maximum drop period synchronised with the peak development period of sixth to sixteenth week after set, indicating nutritional imbalance as one of the major factors influencing fruit drop

    Varietal screening in ginger
    (Kerala Agricultural University, 1981) Nybe, E V; Sivaraman Nair, P C
    Twcntyfive ginger types were screened at the College of Horticulture, Vellanikkara during 1977-78 for the yield and quality attributes such asdrying percentage, oleoresin, oil and crude fibre contents. There was highly significant differences in yield, drying percentage, oleoresin, oil and crude fibre contents among the types studied. Maximum yield was recorded in the type 'Nadia' closely followed by 'Bajpai', 'Maran' and 'Narasapattom'. The maximum oleoresin percentagewas in the type 'Rio-de-Janeiro' and the highest percentage of oil recovery in 'Karakal'. But the yield per hectare of oleoresin and oil was maximum in the type'Maran' Crude fibre content was minimum in 'China' and the maximum in 'Kuruppampady"' The type Thodupuzha' recorded the maximum drying percentage of 25'20 and minimum in Karakal (15.20%). The types 'Nadia', 'Bajpsi' and 'Maran' were found to be relatively superior in performance in view of the higher yield of dry ginger, oleoresin and oil contents.

    Genetic divergence in banana
    (Kerala Agricultural University, 1985) Valsalakumari, P K; Sivaraman Nair, P C; Prabhakaran, P V
    On the basis of multtvariate analysis 62 cultivars of banana belonging to different genomic groups were grouped into 8 clusters considering 22 characters simultaneously. The characters pulp/peel ratio on volume basis followed by the weight of fruit contributed the maximum towards divergence.
