Abstract

The objective of experiment was to know effect of NPK and Biochar application to soil chemical properties of paddy rice. The research was conducted in Empetrieng village, Aceh Besar district, Aceh Province, Indonesia.  The experimental arranged in a randomized complate block design with two factor and four replication.  First factor was NPK 15:15:15 fertilizer application (0 kg ha-1; 60 kg ha-1; and 120 kg ha-1) and second factor was Biochar application (0 ton ha-1; and 10 ton ha-1).  The result showed that : (1) application of Biochar affected significanly to soil pH; (2) application of NPK fertilizer affected significanly to K in soil; and 3) interaction of Biochar and NPK fertilizer application affected significantly to pH and P in soil

Abstract

The objective of this study was to know the effect of biochar residue, compost and urea fertilization on growth and yield of maize.  The research was conducted at University Farm Ie Seum Research Station, Aceh Besar district, Aceh Province, Indonesia.  The experimental arranged in a randomized complate block non factorial design with four replications.  There were eight treatment combinations: P1 (without biochar residue + without compost + without urea), P2 (without biochar residue + without compost + urea), P3 (without biochar residue + compost + without urea), P4 (without biochar residue + compost + urea), P5 (biochar residue + without compost + without urea), P6 (biochar residue + without compost + urea), P7 (biochar residue + compost + without urea), P8 (biochar residue + compost + urea).  Based on the plant growth, biochar residue, compost, and urea fertilizer treatment did not significantly affect on plant height age of 30, 45 and 60 days after planting, leaf number aged 30, 45 and 60 days after planting, stem diameter ages 30, 45 and 60 days after planting. At the P7 treatment (biochar residue + compost + without urea) gave the best value but does not differ significantly with all treatments tested.  Based on plant yield, biochar residue, compost, and urea fertilizer treatment did not significantly affect on cornhusk ear length, cornhusk cob diameter, cornhusk cob weight, cob length without cornhusk, cob diameter without cornhusk, cob weight without cornhusk, and yield.  At P5 treatment (biochar residue + without compost + without urea) cornhusk cobs and P7 (biochar residue + compost + without urea) cornhusk cobs and without cornhusk provide the best value but does not differ significantly with all treatments tested.

Abstract

The objective of experiment was to study effect of biochar and compost application on the best yield of kalian.  The research was conducted at Field Experiment of Provincial Agricultural Service (BPTP), Aceh Province.  The experimental arranged in a randomized complate block design with two factors and four replications.  Biochar consisted of two levels, i.e. without biochar and with biochar 30 ton ha-1. Compost consisted of two levels, i.e. without compost and compost 30 ton ha-1.  The result showed that biochar application affected significantly to stem diameter 7 DAP and not significant to number of leaves and plant height 7, 14, 21, 28 DAP, stem diameter 14, 21, 28 DAP, the 6th of length and width leaf and plant fresh weight.  Compost application affected significantly to number of leaves 14 DAP and the 6th of length leaf; and highly significant to number of leaves 7, 21, 28 DAP, plant height 7, 21, 28 DAP, stem diameter 7, 14, 21, 28 DAP, the 6th of width leaf and plant fresh weight, but not significant to plant height 14 DAP.  There was significantly interaction between biochar and compost application to stem diameter 7 DAP.  There were not interaction to number of leaves and plant height 7, 14, 21, 28 DAP, stem diameter 14, 21,28 DAP, the 6th of length and width leaf and plant fresh weight.
