Abstract

The sacha inchi plant (Plukenetia volubilis L.) produces seeds with high protein content that are beneficial for human health. The planting of sacha inchi on sub-optimal land, such as inceptisol soil, requires eco-enzyme, an organic fertilizer made from environmentally friendly fermented fruit waste. In addition, the use of biological agents, such as arbuscular mycorrhiza, can increase the plant’s ability to absorb macronutrients, such as potassium and phosphorus, from the soil. This study aims to determine the effect of eco-enzyme and mycorrhiza treatments on the growth of sacha inchi plants on inceptisol. A two-factor group randomized design with nine treatments and three replications was employed. The first factor was the concentration of eco-enzyme (0 ml/l, 22.5 ml/l, and 30 ml/l). The second factor was the dose of mycofer (substance containing mycorrhizal spores) (0 g/plant, 30 g/plant, and 40 g/plant). Parameters measured were plant height, number of leaves, root length, root fresh weight, root dry weight, and mycorrhizal infection. The results show that the application of eco-enzyme was able to increase the height of sacha inchi plants in the vegetative phase at 10 and 20 days after planting (DAP) and increase the number of leaves at 30 and 40 DAP. Single application of 40 g/plant of mycofer was able to increase the vegetative growth of sacha inchi on inceptisol. The optimum amount to increase the growth rate of sacha inchi plants was reached through the combination of eco-enzyme at a concentration of 22.5 ml/l and mycofer at a dose of 40 g/plant.

Abstract

Climate change is currently a significant issue that poses a threat to the environment. Climate change can trigger increased rainfall, which promotes erosion in many areas. Erosion can lead to the depletion of nutrients in the soil, ultimately reducing the availability of nutrients for plants and causing a decline in land productivity. This can result in widespread land degradation. To avoid this risk soil conservation is needed. Soil conservation can be done to increase land productivity with chemical methods, such as using soil amendments with polyacrylamide (PAM). PAM is an anionic polymer-based material that can improve soil aggregate stability, infiltration rate, and suppress erosion. The purpose of this study is to determine the effect of PAM on erosion suppression, the loss of N nutrients, and on the growth of sweet corn plants. The results of the analysis showed that there is an effect of PAM on the suppression of erosion and loss of N nutrients in the soil. The dose of PAM of 60 kg/ha was able to suppress erosion by 53.16% and reduce the loss of nutrients N by 15.07%. The most optimal and efficient dose in optimizing sweet corn plant growth is 15 kg/ha.
