Abstract
This research was carried out in the paddy field in the tungkub subak, mengwi village, Mengwi sub-district Badung regency which lasted for 30 days starting from planting November 23 to harvest date December 23, 2019.This study aims to determine the effect of doses of urea and varieties on yield of pokcoy plants using a randomized design basis factorial randomized block design (RAK) consisting of two treatments, namely pakcoy mustard (V) variety and dose of urea fertilizer (U). The interaction of the Pakcoy mustard varieties and the dose of urea fertilizer (VxU) gave no significant difference (p≥0,05) to most of the parameters observed, except for the dry weight parameters of the plant root, the harvest index had a very significant effect (p<0,01) and fresh weight of plant roots that are significantly different (p<0,05) The treatment of mustard greens varieties (v) as large showed no significant effect && except the economical fresh weight plane -1 parameter (p≥0,05) and the number of leaves showed a very real effect. the highest economical fresh weight plane -1 was obtained in Serena variety 60,41 g and the lowest was obtained in cakcoy variety which was only 22,02g. The treatment of urea fertilizer dose has a very significant effect (p<0,01) on most of the parameters observed, except for the parameter of the number of leaves showing very significant (p≥0,05) and the oven dry weight parameters of the economic results of plants, oven dry weight economic results ha -1 shows no significant effect (p≥0,05) wile to the highest fresh weight economical yield ha -1 was obtained at 375 kg ha -1 urea fertilizer dosage treatment which was 20.87 t or an increase of 103.02% compared to the lowest in the 0kg ha -1 urea fertilizer dosage treatment which was only 10, 28 t.
