Karnataka is experiencing a significant shortfall in summer rainfall, which is expected to adversely impact pre-kharif agricultural activities and reduce yields of key crops such as mango and coffee. According to data from the Karnataka State Natural Disaster Monitoring Centre (KSNDMC), the state received only 48 mm of rainfall between March 1 and May 7, against a normal average of 54 mm for the same period.
Rainfall Deficit Details
The deficit, though seemingly modest at 6 mm, has been unevenly distributed across the state. Several districts, particularly in the southern and coastal regions, have recorded much larger shortfalls. This has led to soil moisture stress, delaying sowing operations for pre-kharif crops and affecting the flowering and fruit-setting stages of horticultural crops like mango and coffee.
Impact on Mango Crop
Mango growers are particularly worried as the deficit rains coincide with the critical flowering and fruit development phase. The lack of adequate moisture has resulted in poor fruit set and increased incidence of fruit drop. Experts estimate that the mango yield could drop by 15-20% this season compared to the previous year.
Impact on Coffee Plantations
Coffee plantations in the traditional coffee-growing districts of Chikmagalur, Kodagu, and Hassan are also facing challenges. The summer rains are essential for the growth of coffee berries and for maintaining soil moisture during the dry period. With deficient rainfall, coffee yields are expected to decline by around 10-12%, affecting both Arabica and Robusta varieties.
Pre-Kharif Operations Affected
The pre-kharif season, which includes land preparation and sowing of short-duration crops, has been delayed in many parts of the state. Farmers are unable to proceed with ploughing and sowing due to insufficient soil moisture. This could push back the main kharif sowing schedule, potentially affecting overall agricultural output.
Government Response
The state agriculture department has advised farmers to adopt moisture conservation techniques and consider alternate crops if the deficit persists. The Karnataka government is also monitoring the situation and may announce relief measures if the rainfall deficiency continues to worsen.
Meteorological forecasts suggest that the deficit may persist in the coming weeks, with below-normal rainfall expected until mid-May. Farmers are urged to stay updated with local advisories and take necessary precautions to mitigate crop losses.
