RESPON TANAMAN SAWI (Brassica juncea L.) TERHADAP PERTUMBUHAH DAN HASIL DALAM PERLAKUAN PUPUK KANDANG AYAM DAN PUPUK NPK 16:16:16

Abstrak

This study aims to find out, Is there a response between mustard plants (Brassica juncea L) to growth and yield in chicken manure treatment, Is there a response of mustard plants (Brassica juncea L) to growth and yield in applying NPK fertilizer 16:16:16, Is there an interaction between chicken manure and NPK 16:16:16 fertilizer to the growth and yield of mustard plants (Brassica juncea L) carried out at UPTD. BIH. Johor Medan Building for the 2023/2024 implementation year. The type of research conducted in this study is Group Random Design (RAK), which consists of 2 factors, namely the first factor of chicken manure dose (A), which consists of 4 levels, namely: A0 = 0 kg / plot (without control), A1 = 1.5 kg / plot, A2 = 2 kg / plot, and A3 = 2.5 kg / plot. The second factor is the dose of NPK fertilizer 16:16:16 (N) which consists of 4 levels, namely: N0 = 0 g / plot (without control), N1 = 50 g / plo, N2 = 100 g / plot, and N3 = 150 g / plot. The results showed that the dose of chicken manure had no real effect on the height of plants aged 7 – 28 Hst, the number of leaves aged 7 – 21 Hst at the age of 28 Hst had a real effect, gross weight / sample and net weight / sample age 28 Hst, gross weight / plot and net weight / plot at the age of 28 Hst the dose of chicken manure was found at A2 (2 kg / plot). The dose of NPK fertilizer 16:16:16 has a very real effect on plant height aged 21 – 28 Hst, has a real effect on the number of leaves aged 14 Hst and has a very real effect on the age of 21 – 28 Hst, has a very real effect on leaf width, leaf length, gross weight / sample and net weight / sample, gross weight / plot and net weight / plot age 28 Hst. There is an interaction between the two treatments has a very real effect on the height of plants aged 7 Hst,  significant effect on leaf count age 21 Hst and very real effect on age 28 Hst, no real effect on leaf width and leaf length, no real effect on gross weight/sample and net weight/until.
