Abstract
Abstract Mycorrhizal inoculation and plant nutrition have an important role in increasing the yield of maize-soybean intercropping in suboptimal land. The experimental design used was a factorial randomized block design with two factors, the first factor was AMF inoculation which consisted of two levels, namely M 0 = without AMF inoculation and M 1 = with AMF inoculation, and the second factor was plant nutrition treatment. with four levels, namely U 0 = without the addition of nutrients, U 1 = with the addition of 100% dose of inorganic fertilizer (maize = urea 300 kg ha -1 and Phonska 200 kg ha -1 , soybean = 60 kg ha -1 Urea and 120 kg ha -1 Phonska), U 2 = with the addition of 100% dose of cattle manure and U 3 = with the addition of 50% dose of cattle manure (6 t ha -1 ) plus 50% dose of inorganic fertilizer (maize = urea 150 kg ha -1 and Phonska 100 kg ha -1 , soybean= 30 kg ha -1 Urea and 60 kg ha -1 Phonska). The results showed that AMF inoculation treatment and application of 50% inorganic fertilizer plus 50% organic fertilizer gave the highest yield with maize grain weight of 4.3 tons ha -1 and soybean grain weight of 0.5 tons ha -1 .
