Soil test based fertilization for targeted yields of mulberry

Author(s): P. C. BOSE, D. DAS* AND R. KAR
Abstract: For quantitative evaluation of the efficiency of soil tests and fertilizer response to rainfed mulberry (Marus alba L.), variety BC259, through Mitscherlich-Bray equation in the sub-tropical region of West Bengal and Sikkim, two field experiments were conducted at Kalimpong, West Bengal. The Mitscherlich-Bray equation is based on the principle that the native and the added nutrients comprehend different efficiency factors. Results indicated that the greater efficiency of P- and K-fertilizers over soil contributed more share of biomass production from the applied nutrient. And, between P and K, the native soil nutrient supplying efficiency was greater in respect of P than ofK. On the basis of soil test values through Mitscherlich-Bray equation, the fertilizer prescription for rainfed mulberry of sub-tropical region of West Bengal and Sikkim has been worked out..
