Description Analysis of rainfall and temperature of hill zone (high rainfall tract) of Karnataka (part of Westem Ghats) carried out for 23 years (1986-2008) indicated that the tract received a mean rainfall of 2,617 mm in 123 rainy days with maximum contribution (80.94 %) from south west monsoon (June to September). July was the rainiest month (799.6 mm) with 28 rainy days. There was no significant trend in mean annual rainfall. The mean monthly maximum temperature (TMAX) ranges between 23.7 °C (August) to 31.7 ·C (March) and mean monthly minimum temperature (TMIN) was in the range of 13.2 °C (January) and 18.8 °C (May). Temperature trend indicated that annual TMAX was increasing (R2::0.4903) while TMIN decreasing (R2=0.3656). Though the tract receives high rainfall, moisture stress is common between December and March and adequate moisture conservation (or irrigation wherever possible) is essential, particularly, for perennial crops in the juvenile stage. Based on the analysis, it is suggested that first dose of fertilizer application, prophylactic plant protection and shade regulation has to be completed during 18th to 21" week (30th April-27th May) during pre-monsoon time and second schedule has to be adopted during 36th (3-9 September) to 39th week (24-30 September). These operations may continue up to 41" week for cardamom and black pepper crops depending upon receipt ofrainfall. Beyond 41" week (8-t4th November), the rainfall receipt is less and earthing up and mulching for cardamom and mulching for black pepper are to be done preferably before 43nl week (22-28th November) to conserve moisture and reduce the evaporation.
