Pengaruh Tricho Kompos Jagung Dan NPK 15:15:15 Terhadap Pertumbuhan Serta Produksi Tanaman Sawi Pakcoy (Brassica Rapa. L)

This research was conducted at the Experimental Garden of the Faculty of Agriculture, Riau Islamic University, Jalan Kaharuddin. Nasution Km 11 No. 113, Perhentian Marpoyan, Airingin Village, Bukit Raya District, Pekanbaru City. This research was conducted for 2 months starting from June to July 2020. The purpose of this study was to determine the effect of the interaction between tricho organic fertilizer compost corn and fertilizer npk 15:15:15 on the growth and production of pakcoy mustard plants. The design used in this study was a completely randomized factorial design consisting of 2 factors. The first factor is Tricho compost of corn which consists of 4 levels, namely 0, 50, 100 and 150 g / plant and the second factor is fertilizer npk 15:15:15 consisting of 4 levels, namely 0, 0.75, 1.5 and 2.25 g / plant, each treatment consists of 3 repetitions in order to obtain 48 experimental units. In the experimental unit there were 4 plants and 2 plants used as observation samples taken randomly so that 192 plants were obtained. If F count is greater than F table, then a further test of honest real difference (BNJ) is continued at the 5% level. Based on the results of the research that has been carried out, it is concluded as follows: The interaction of tricho corn compost and NPK 15:15:15 is significant on plant height, number of leaves and root volume, where the best treatment is tricho compost of 150 g / plant and NPK fertilizer 15:15:15 2.25 g / plant. The main effect of corn compost tricho was significant for all observed parameters. The best treatment is tricho compost corn 150 g / plant. The main effect of NPK fertilizer dose 15:15:15 was significant on all observed parameters. The best treatment was NPK fertilizer 15:15:15 2.25 g / plant
