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. |
