    Performance evaluation of certain rice cultivars
    (Kerala Agricultural University, 1993) Susamma P George; Devadas, V S; Sansamma George; Pillai, G R
    Experiments were conducted with 12 rice cultivars for three consecutive years from 1984-85 to 1987-88 during kharif and rabi seasons in randomised block design. Pooled analysis of the data for kharif and rabi seasons indicated that MO 4 registered the highest grain yield in the kharif (5068 kg/ha) and rabi (4891 kg/ha) crop seasons. Hence MO 4 can be recommended for cultivation in Wynad in both the seasons. Edavaka was also found to be a promising cultivar when grain yield, straw yield and comparatively shorter duration were considered and hence requires further studies.

    Seedling progeny analysis in selected cashew types
    (Kerala Agricultural University, 1984) Susamma P George; Gopimony, R; Gangadharan, P
    Seedling progeny analysis of two different types of cashew namely Kottarakara 1 and Kottarakara 27 was done by raising nursery of seedlings collected from 30 mother trees each from the two types. The experiment was conducted at the College of Agriculture, Vellayani during 1981 -82. Analysis of seedling characters revealed that the two types differed significantly in the recovery of vigorous seedlings. Kottarakkara 27 was found to be significantly superiorto Kottarakkara 1 in this character. The recovery was more from the medium yielding group compared to low and high yielders in both types In the recovery of prepotent trees ths three yield groups as wall as the two types werefound to be not significantly different.

    Weed control in wetland rice in the high ranges of Wynad
    (Kerala Agricultural University, 1993) Sansamma George; Aipe, K C; Susamma P George; Pillai, G R; Balakrishna Pillai, P
    A field investigation was carried out at the Regional Agricultural Research Station, Ambalavayal, Wynad, Kerala for evaluating some of the herbicides for weed control in rice and also to standardise the best time of hand weeding for rice in Wynad. Four herbicides, alone and in different combinations and also two different time of hand weeding were compared. The results indicated that use of herbicides for weed control in rice was economically advantageous for the high ranges of Wynad. Though not statistically significant, hand weeding on 30th and 60th days after transplanting (DA I) was found superior to hand weeding at 20th and 40th DAT both in terms of weed control and yield.
