PENGARUH KONSENTRASI PUPUK ORGANIK CAIR NASA TERHADAP PERTUMBUHAN DAN HASIL TANAMAN PAKCOY (BRASSICA CHINENSIS L.)
Pakcoy consumption needs in Indonesia in 2018 amounted to 635,982 tonnes and in 2019 amounted to 652,723 tonnes. Meanwhile, the productivity of pakcoy plants in 2018 was 6.59 tonnes/ha and in 2019 5.72 tonnes/ha. NASA POC has a function that can improve chemical properties because it contains macro and micro nutrients, as well as improving soil microorganisms that are beneficial for plants. This research aims to determine the best dose of NASA POC fertilizer for the growth and yield of pak choy (Brassica chinensis L.). This research was carried out in Tanjung Pering, North Indralaya District, Ogan Ilir Regency, South Sumatra, from August to September 2023. The method used in this research was the Randomized Block Design Method (RBD) which consisted of 4 treatments and 3 replications, There were 3 replications for each treatment, so there were 12 experimental units and 36 total plants. The research treatments were P0 = Control / No POC, P1 = Giving Nasa POC with a concentration of 1 cc/l, P2 = Giving Nasa POC with a concentration of 2 cc/l, P3 = Giving Nasa POC with a concentration of 3 cc/l. The parameters observed were plant height, number of leaves, leaf width, leaf length, plant fresh weight, root fresh weight, stem fresh weight, leaf fresh weight, plant dry weight, root dry weight, stem dry weight, leaf dry weight. Diversity analysis used the ANOVA test and continued with the 5% BNT test.
