Sumarno Sumarno, Hery Widjianto, Rosinta Kusuma W

Abstract

This research conducted to determine the exact formula and dosage to increase the uptake of N and increase yield of green mustard. The research conducted at Jumantono dryland research center, Karanganyar and Laboratory  of Chemistry and Soil Fertility, Faculty of Agriculture UNS Solo. This study uses a randomized complete block design (RCBD) using 5 formulas as the first treatment factor and 4 dosages as second treatment factor. The data analysis used F test level of 5% and if significant continued by DMRT (Duncan Multiple Range Test) level of 5%. The variables of this research were weight of wet stover, weight of dry stover, N total and absorption of N. The results showed that the combination of dosage and formula of natural fertilizers can increase N uptake and yield of mustard on the ground Alfisols.

Keywords
