By using drip irrigation and sprinklers and among other measures, the crops can be prevented from excess heat, which has been prevailing in many southern districts due to the El Nino effect, as predicted by the IMD authorities.

In Theni district alone, farmers raised mango, guava, grapes, coconut, cardamom, tea, coffee and cashew crops in about 50,000 hectares. Likewise, plantain, papaya, tomato, small onion, chillies, ladies finger and among others were grown in 15,000 ha, said District Collector Ranjith Singh here on Saturday.

Under such circumstances, excess heat and scorching sun has come as a big concern to many farmers in the district.

After examining very many blocks, the Horticulture department officials have suggested the farmers to water the plants only during early mornings or late evenings. By using a small quantity, say 1 % of potassium chloride solution on the leaves, the water evaporation could be reduced and thus it protects the crops from withering.

The officials said that watering shpuld be avoided during 11 a.m. to 3 p.m., as it leads to swift evaporation and thus may not really benefit the roots.

In Virudhunagar district, Collector N O Sukaputra said that farmers should examine the modalities of having roof sheds for short-term crops and also adapt the techniques of miyawaki forest, which brings in shade and save the crops.

The Horticulture department officials have plans for each grower and thus the crops could be saved to a major extent. The farmers raising paddy, maize, pulses, sesame, groundnut, flowers and fruits may get in touch with the officials and thus use the tips which would help in overcoming the climate change in the region.

Incidentally, widespread rains in the last 24 hours in many southern districts has brought in much needed relief to the public and the farmers, officials added.
