Plant physiologist Somashekhargouda Patil said while 25-28 degrees Celsius is optimum for Arabica coffee, 28-30 degrees is optimum for Robusta coffee. 50% to 60% shade for Arabica and 30% to 40% for irrigated Robusta and 40% to 50% shade are required for rain-fed Robusta cultivation, according to him. He said temperature will be 3 to 4 degrees less in plantations with well-maintained shade.
Temperature will increase and affect soil moisture,” he said. “We have studied it on our CCRI campus,” he said. Chikkamagaluru: As temperatures soar, scientists have urged coffee planters to maintain optimal overhead shade canopy for sustainable, high-quality coffee production that meets international market standards. Scientists at Central Coffee Research Institute (CCRI), Balehonnur, suggested a package of practices during a buyers’ and sellers’ meet organised by SM Sehgal Foundation at Balehonnur. Proper maintenance of shade yields high-quality coffee needed for the international market, he added. “If proper shade is not maintained, it will badly affect plantations.
