CONTRIBUTION OF ORGANIC FERTILIZER OF TITONIA PLUS AND MICRO NUTRIENTS TO IMPROVE RICE PRODUCTION USING SRI METHODS

摘要

A series of field experiments were conducted in the farmer lands in two location in Padang, Koto Panjang and Koto Tingga, in 2015. The purpose of the experiment was to establish the formula of organic fertilizer derived from titonia with micro nutrients, Zn and Mn, in order to reduce synthetic fertilizer application by 50% to get rice yield about 7 tons ha-1. The experiments were conducted using Randomized Block Design with 6 treatments and 3 replications.The treatments were P = OFTP + 3.0 kg Mn / ha + 0 kgZn / ha, Q = OFTP + 3.0 kg Mn / ha + 3.0 kgZn / ha, R = OFTP + 4.5 kg Mn / ha + 6 kg Zn / ha, S= OFTP + 4.5 kg Mn / ha + 9 kgZn / ha, T = OFTP only, U = 100% synthetic fertilizer only. The experimental results showed that treatment of Micro nutriens addition to OFTP to increase yield paddy in Padang city is TOFP+3.0kgMn/ha+0kgZn/ha and OFTP+3.0kgMn/ha+3.0kgZn/ha to increasing of yield 80 g/clump.ud
