Influence of Tempeature, Rainfall and Relative Humidity on Productivity of Groundnut in Northern Transition Zone (Zone 8) of Karnataka*
Abstract
The groundnut cultivar JL 24 was tried during kharif season of 2012 the experiment was designed in randomized complete block design consisting of three replications and eleven ratios of nitrogen (N) and phosphorus (P2O5) fertilizers with potassium level as constant (25 kg K2O ha−1) at MARS, UAS, Dharwad. The results revealed that groundnut production varied with other variables namely, relative humidity, number of rainy days, maximum and minimum temperature. The rainfall received during the crop growth period of groundnut (23-07-2012 to 31-10-2012) was 295.00 mm with 26 rainy days. The mean relative humidity, mean maximum temperature, mean minimum temperature observed during the entire growth period of groundnut was 73.36%, 26.98°C and 19.00°C respectively. In general, the weather parameters prevailed during the crop growth period of groundnut was favorable for the normal growth. The mean pod yield and kernel yield of groundnut in the experiment varied from 2194 to 3310 kg ha−1 and 1660 to 2441 kg ha−1, respectively.
