Abstract

This study aims to analyze the interaction between paclobutrazol (PBZ) with Nitrogen (N) nutrients on the growth and yield of potato (Solanum tuberosum L.) var. Granola L. It was conducted in Mokobang Village, Modoinding District, South Minahasa Regency. This research was carried out in the form of field experiments and laboratory analysis. The treatment consisted of two factors: A. PBZ at doses: 1) 3 kg PBZ/ha, 2) 3.5 kg PBZ/ha, and 3) 4 kg PBZ/ha. B. Nitrogen nutrient at doses: 1) 200 kg N/ha, 2) 250 kg N/ha, 3) 300 kg N/ha. The placement used RGD and each treatment was repeated 3 times, there were 27 combinations (3 x 3 x 3). The results showed an interaction between the growth and yield of potato plants. Generally, higher doses of PBZ and N increased the growth of plant height, number of leaves, number of branches, leaf wet weight and dry weight, stem wet weight and dry weight, root wet weight and dry weight, plant wet weight and dry weight, and leaf chlorophyll content and tuber yield. The interaction of PBZ and N increased the tuber yield of potato plants per hectare. The highest tuber productivity resulted from the treatment of 4 kg PBZ and 200 kg N/ha (P3N1) at 37.9 tons/ha, while the lowest productivity resulted from the combination of 3 kg PBZ and 250 kg N/ha (P1N2) at 27.3 tons/ha.

Abstract

Spinach (Amaranthus sp) is a plant belonging to the Amaranthaceae family. Spinach is one of the oldest food plants in the world originating from America, which has been cultivated around 6700 years BC and is now spread throughout tropical and subtropical areas throughout the world. Copra fumigation ash contains macro and micro nutrients that plants need, one of which is potassium. This research aims to determine the effect of copra fumigation ash on the growth of spinach plants. This research was carried out at the Green House, Faculty of Agriculture, Sam Ratulangi University, Manado, North Sulawesi from June to July 2024. This research used a Randomized Group Design (RAK) with six treatments and four replications consisting of Without Ash Copra Fumigation (K0), 5 tons Copra Fumigation Ash/ha (K1), 10 tonnes of Copra Fumigation Ash/ha (K2), 15 tonnes of Copra Fumigation Ash/ha (K3), 20 tonnes of Copra Fumigation Ash/ha (K4) and 25 tonnes of Copra Fumigation Ash/ha ( K5). The research data were analyzed using the F test using the Microsoft Office Excel program to determine the effect of copra fumigation ash treatment on the growth of spinach plants. The research results showed that copra fumigation ash had a significant effect on the variable height of spinach plants but not on the number of leaves and width of spinach leaves. Copra fumigation ash also has a very significant effect on the fresh weight of spinach plants. It is recommended to use copra ash at a dose of 20 tons/ha as the recommended dose for spinach cultivation activities.
