ArticleItem Open Access Adaptability of cauliflower genotypes in the high ranges of Kerala(Kerala Agricultural University, Vellanikara, 2002) Pradeepkumar, T; Sajith Babu, D; Aipe, K C; KAUThesisItem Open Access Effect of potassium, magnesium and sulphur on the yield and quality of sesamum(Department of Agronomy, College of Agriculture, Vellayani, 1981) Aipe, K C; KAU; Sadanandan, NAn experiment was conducted in the summer rice fallows of the Rice Research Station, Kayamkulam during 1930 to study the effects of three levels of potassium (0, 30 and 60 kg KgO/ha) three levels of magnesium ( 0,15 and 30 kg Kg/ha) and three levels of sulphur (0, 15 and 30 kg S/ha) on the growth, yield , oil and protein content and chemical composition and uptake of mineral, nutrients of sesamum. The field trial was laid out as a 33 factorial experiment confounding KMS in replication - 1 and KMS2 in replication -2 .ArticleItem Open Access Influence of weather on the yield of pepper cv. panniyur 1 (Piper Nigrum L.)(Kerala Agricultural University, 1999) Pradeepkumar, T; Kumaran, K; Aipe, K C; Manomohandas, T P; KAUInfluence of weather on the yield of black pepper variety Panniyur 1 was studied by resorting correlation and regression analysis. Among the different weather variables, mean maximum temperature in March first fortnight and June second fortnight, total sunshine hours received during February first fortnight, March first fortnight and April second fortnight, total rainfall during March second fortnight and September second fortnight- mean maximum relative humidity during March first fortnight and mean minimum relative humidity during March second fortnight and July first fortnight were found to be significantly correlated with the pepper yield of succeeding year. By combining three weather variables viz., mean maximum temperature during March first fortnight, mean maximum temperature during June second Ibrtnigiit and mean minimum relative humidity during July first fortnight, a regression equation was derived with an R2 ue y can be used in predicting the pepper yield at the end of July first fortnight.ArticleItem Open Access Performance of strawberry varieties in Wayanad District of Kerala(Kerala Agricultural University, Vellanikara, 2002) Pradeepkumar, T; Sajith Babu, D; Aipe, K C; KAUArticleItem Open Access 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; KAUA 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.
