    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.

    Influence of weather on the yield of pepper cv. panniyur 1 (Piper nicrum L.)
    (Kerala Agricultural University, 1999) Pradeepkumar, T; Kumaran, K; Aipe, K C; Manomohandas, T P
    Influence 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 fortnight and mean minimum relative humidity during July first fortnight, a regression equation was derived with an R2 can be used in predicting the pepper yield at the end of July first fortnight.
