Abstract

Sweet corn (Zea mays, Saccaharata sturt) is a food crop that is in great demand by people in Indonesia because it has a sweeter taste than ordinary corn. This sweet taste is because sweet corn has high glucose levels. The glucose content of sweet corn per 100 g has a glucose content of 16%. Sweet corn also has high nutritional content and economic value (Hidayah et al. 2020). Dolomite fertilizer is a soil savior from the onslaught of chemicals that function to neutralize soil acidity or increase soil pH. In addition to the application of dolomite fertilizer, N, P, and K fertilizers contain three macronutrients, namely nitrogen (N), phosphorus (P), and potassium (K). This research was conducted in May–July 2023 in the experimental field of the Faculty of Agriculture, Indonesian Community Development University UPMI Medan, on Jl. Pasar 12 Marindal II Village Hall, Patumbak District, Deli Serdang Regency, North Sumatra Province. This research was carried out using a randomized block design (RAK) in a factorial pattern, grouping based on Factor I: dolomite (D), which consists of 3 levels, namely: D0 = no treatment, D1 = 0.5 kg/plot, and D2 = 1 kg/plot. Factor II: application of NPK (N) fertilizer, which consists of 3 levels, namely: N0 = no treatment, N1 = 10 grams/plant, and N2 = 20 grams/plant. The single effect of applying NPK fertilizer at the level of N2 = 20 grams per plant has the effect of increasing the number of pods per sample plant based on the 5% DMRT test. The interaction effect of NPK (N) fertilizer application and dolomite fertilizer application had no effect on plant length, number of leaves, number of pods per sample plant, fruit length, or weight for sample plants.

Abstract

Oil Palm (Elaeis guinensis Jacq.) belongs to the Arecaceae family. Indonesia contributes 48% of international CPO production (Nasamsir and Romadoni, 2020). Palm oil is a raw material for producing vegetable oil which has many benefits as edible oil, industrial oil and biodiesel (biofuel). This research will be carried out from April 2023 to June 2023, at the Experimental Field of the Faculty of Agriculture, Indonesian Community Development University, Medan. On Jl. Market village hall 12 Marendal II, Patumbak District, Deli Serdang Regency. This research was conducted using a factorial randomized block design (RBD) which consisted of two factors, namely: Factor I was KNO3 administration which consisted of 3 levels, namely: K0 = without KNO3 administration, K1 = 30 g/polybag KNO3, K2 = 60g/polybag KNO3. Factor II was the application of Cattle Manure which consisted of 3 treatment levels, namely: C0 = Without Giving Cattle Manure, C1 = 100g/polybag of Cattle Manure, and C2 = 200g/polybag of Cow Manure. The results showed that the single effect of giving cow manure had an effect on increasing plant height (at 3 weeks old, 6 weeks old, and 9 weeks old), number of leaves (at 3 weeks old), leaf width (at 3 weeks old, 6 weeks old, and 9 weeks old), and leaf diameter (at 3 weeks old and 6 weeks old). Single effect Urea administration had an effect on increasing the growth of the number of leaves at the age of 3mst but had no significant effect on plant height, leaf width and stem diameter. The interaction effect of KNO3 fertilizer and cow manure had no effect on plant height, number of leaves, leaf width, and stem diameter.
