Abstract

Post tin mining land can be used as agriculture land with ameliorant application and plant spacing modification. This research aimed to study the ameliorant type and plant spacing that affects the growth and yield of maize in post tin mining land. This research was conducted in Post-Tin mining land, Bangka, from February to May 2020. This research used Factorial Randomized Block Design with two factors and three replications. The first factor was ameliorant application consisted of Topsoil (K1), N, P, K + Topsoil (K2), Block compost of cassava peel waste + Topsoil (K3). The second factor was plant spacing (30cm x80 cm (J1); 50 cmx60 cm (J2); 70 cmx40 cm(J3)). The result showed that ameliorant application gave a significant effect on the growth and yield of maize parameters in post tin mining land. Plant spacing gave the best effect on cop production/ha, dry seed weight, and dry seed production/ha. NPK + Topsoil ameliorant with 30 cm x 80 cm plant spacing gave the best interaction on leaves number, cop diameter, and dry seed weight of maize in post tin mining land.
