Abstrak

This study aims to determine the appropriate dose of manure and NPK fertilizer by increasing production yields and optimal plant growth. This research was conducted in the village of Diski, Sunggal District, Deli Serdang Regency. From March to May 2022. This study used a factorial randomized block design (RAK) consisting of 2 treatment factors with the symbol K consisting of 3 levels, namely; (K₀) Control (K₁) 1.5 kg/plot (K₂) 2 kg/plot (K₃) 2.5 kg/plot. The two doses of cow manure with the symbol S consist of 4 levels, namely; (P₀) Control (without fertilizer), (P₁) 50 gr/plot, (P₂) 100 gr/plot, (P₃) 150 gr/plot. so that 16 treatments were obtained, each treatment was repeated 3 times, the observation data was then analyzed using the F test at 5% level if the difference was real then the test was followed by DMRT. The results showed that the dose of manure treatment had a very significant effect on plant height, number of leaves, leaf length, leaf width, and stem diameter of mustard greens. Treatment with NPK fertilizer had a very significant effect on plant height, number of leaves, leaf length, leaf width, and plant stem diameter.
