Abstract

This study aims to obtain the right dosage of nitrogen and potassium fertilizers as well as the interaction between nitrogen and potassium in increasing the growth and yield of sweet corn (Zea mays var. saccharata). This study used a factorial randomized block design consisting of 2 treatment factors, namely nitrogen and potassium fertilizer treatment, with 3 replications. Factor I Nitrogen fertilizer treatment with the dose: N0: Without nitrogen fertilizer (control), N1: Nitrogen fertilizer 150 kg/ha Urea, N2: Nitrogen fertilizer 300 kg/ha Urea. Factor II Potassium Fertilizer : K0 : Without Potassium Fertilizer (control), KI : Potassium Fertilizer 200 kg/ha K2O, K2 : Potassium Fertilizer 300 kg/ha K2O. The parameters observed in this study were plant height (cm), cob length (cm), cob weight (grams), cob diameter (grams) and dry chestnut weight (grams). The results of the analysis of variance showed that the treatment of nitrogen fertilizers and potassium fertilizers had a significant to very significant effect on all observed variables. The interaction of nitrogen and potassium fertilizers had a significant effect on cob weight and had a very significant effect on plant height, cob diameter and dry matter weight and had no significant effect on cob length.

Abstract

Dry land is very potential to be developed into agricultural land, one of which is planting peanuts, although it has constraints such as low pH and low soil fertility. Efforts can be made to improve soil fertility by applying organic fertilizer. Organic fertilizers are expected to improve the soil's physical, chemical, and biological properties and provide nutrients that peanut plants need. This research aims to obtain the right organic fertilizer type and dosage to increase peanut production. This research was conducted in farmers' fields in Margo Bhakti Village, Block C unit II, Mesuji District, Ogan Komering Ilir Regency (OKI) from March to June 2021. The layout in the field used a factorial RAK design with 9 treatment combinations repeated 3 x. Type of Organic Fertilizer: cow manure organic fertilizer, chicken manure organic fertilizer, biofertilizer. Dosage of organic fertilizer: 200 kg/ha, 400 kg/ha, 600 kg/ha. The heaviest pod weight was achieved in the combination of biofertilizer treatment at the dosage of 400 kg/ha at 89.67 g/plant or 6.97 kg/plot and increased production by 109.31% when compared to cow manure organic fertilizer at the rate of 200 kg/ha.
