Farm scientists have advised potassium chloride spray to prevent damage from sudden rise in temperature
Scientists of the premier research body — Indian Institute of Wheat and Barley Research (IIWBR), Karnal — have issued an advisory for wheat crop for the second fortnight of February.
They have advised farmers to give light irrigation wheat crop as per requirement. In case of strong windy weather situation, irrigation should be stopped to avoid lodging that may result in yield loss.
Farmers, who have the facility of sprinkler irrigation, can irrigate their field with sprinkler for 30 minutes in the afternoon in case of rise in temperature. Farmers having drip irrigation facility need to ensure proper moisture in the crop to avoid stress.
To avoid the damage caused by terminal heat in case of sudden rise in temperature, two sprays of potassium chloride 0.2% at jointing and heading stage may reduce the losses.
Farmers are advised to regularly monitor wheat crop for yellow rust disease regularly. In case of yellow rust disease, consult the agricultural expert at the nearest Krishi Vigyan Kendra, research institute or state agriculture department staff. If yellow rust is confirmed, spray of 200 millilitres (ml) Propiconazole 25 EC mixed with 200 litres of water for one acre is recommended.
Keep a constant watch for leaf aphid (chepa) in wheat. If the population of leaf aphids exceeds the economic injury level (ETL-10-15 aphids/tiller), then spray with quinalphos 25% EC 400 ml quantity in 200-250 litres of water and spray at the rate of per acre.
