Abstract

Soil physical properties play a crucial role in supporting the productivity and sustainability of plantation land. However, changes in management systems, both organic and conventional, often have a significant impact on soil physical conditions. Problems faced in conventional plantation land include decreased soil structure quality, increased soil density, and decreased air infiltration capacity, caused by intensive use of chemicals and unsustainable land management. On the other hand, organic management systems are considered capable of improving several soil physical characteristics, such as increased porosity, aggregate stability, and soil ability to retain moisture, in-depth research is still needed to validate these benefits quantitatively. This study aims to compare the effects of the two management systems on soil physical properties, including texture, structure, porosity, density, and air content. Soil samples were taken from organic and conventionally managed plantation lands, and measured using standard laboratory methods to obtain comprehensive data. The findings of this study are expected to provide insight into the impact of each management system on soil physical quality, as well as become the basis for recommendations for more sustainable land management strategies in the future.

Abstract

This study aims to determine the effect of different planting distances on the growth and yield of banana plants in open fields. The research was conducted experimentally using a Randomized Complete Block Design (RCBD) with four spacing treatments: 2 x 2 m, 2.5 x 2.5 m, 3 x 3 m, and 3.5 x 3.5 m, each repeated four times. Observed parameters included plant height, number of leaves, stem diameter, number of bunches, bunch weight, and number of fruits per bunch. The results showed that planting distance significantly affected banana plant growth and yield. The 3 x 3 m spacing treatment produced the best vegetative growth and the highest yield compared to the other treatments. Therefore, a 3 x 3 m spacing is recommended for banana cultivation in open fields to achieve optimal results.
