Abstract

This study aims to compare oil palm growth and yield in various topography on one stretch of land. Topography can affect the rate of erosion on agricultural land. High erosion rates transport nutrients to lower places, reducing land productivity, including oil palm plantations. It conducted the research by taking data on the growth and production of palm oil at PT. Perkebunan Nusantara XIV Keera-Maroangin Unit in October - December 2020. Observations were made of oil palm plantations on 3 types of land topography, namely (1) flat land: slope <3%, with a height difference <2 m, (2) undulating land: slope 8-15%, with a height difference of 10-50 cm, and (3) hilly land: slope 15-30%, with a height difference of 50-300 cm. Available secondary data is data from samples taken using a systematic random method. The sample data was then statistically processed using the two-party test method at the 0.05 level. The results showed that all growth parameters, namely plant height (98.09 cm), trunk circumference (301.94), frond length (413.94 cm) and bunch weight production (6.76 kg) of oil palm were found to be better on land with flat topography than other types of topography, while undulating land is better than sloping land, except for the parameter of frond length, oil palm growth and production are better than sloping land.

Abstract

The provision of mycorrhizal fungi makes phosphorus available in the soil because mycorrhizae play a role in dissolving phosphorus bound to the soil. Soybeans need phosphorus, a significant limiting factor for plant growth and production. The study aims to determine the optimal dose of vesicular-arbuscular mycorrhizal (VAM) inoculation and SP36 fertilizer on Tanggamus soybean varieties. The study was arranged using a Split Plot Design (RPT), with the main plot, namely the MVA dose consisting of 4 levels, namely: without mycorrhiza (m0), mycorrhiza 5 g.plant-1 (m1), 10 g.plant-1 (m2), 15 g.plant-1 (m3); and the subplot is SP36 fertilizer consisting of 4 levels, namely: Without SP36 (f0), SP36 7.7 g.plant-1 (p1), 11.5 g.plant-1 (p2), 15.4 g.plant-1 (p3). There were 16 treatment combinations consisting of 3 replications and 48 experimental units. The variables observed were plant height, root fresh weight, shoot fresh weight, flowering days, number of seeds per plant, and seed weight per plant. The results showed that the treatment of vesicular-arbuscular mycorrhiza 15 g.tan-1 with SP36 fertilizer 7.7 g.tan-1 increased growth, especially at a plant height of 50.68 cm (4.84%) and increased soybean plant yields, as shown by seed weight of 52.33 g.tan-1 (60.18%) compared to the treatment of SP36 fertilizer without mycorrhizas (15.4 g.tan-1).
