Abstract

Irrigation is the most important part of plant cultivation to meet the water needs for plant growth and yield. However, irrigation is a common problem in dryland areas. The drip irrigation system is an alternative to solve the problem of water droplets that can improve water use efficiency. One consideration when using drip irrigation is designing the irrigation layout so that the water supply to each plant is uniform. This study evaluated two layout layouts of drip irrigation systems for pok choi plants (Brassica rapa var. chinensis L.) with different planting media. The method used a split-plot design with 2 factors. Variation of drip irrigation system (V) was the main plot which consists of 2 levels, namely variation 1 (V1) and variation 2 (V2). Media type (M) served as a subplot comprised of 3 levels, namely soil (M0), soil+charcoal husk (M1), and soil+cocopeat (M2). The feasibility of these two drip irrigation system designs included drip discharge values, water uniformity coefficient, water distribution uniformity, and storage efficiency. Based on the evaluation of the feasibility of drip irrigation system design, design 1 (V1) gave better values for the average value of drip discharge (0.16 l/minute), uniformity coefficient (99.71%), uniformity of water supply (82.11%), and storage efficiency (73.89 %). The layout of the drip irrigation had a significant effect on the height of pok choi plants on 1 and 2 WAP.

Abstract

Soybean (Glycine max Merril.) is a strategic food crop whose productivity must be improved to meet increasing national demand. The use of Plant Growth Promoting Rhizobacteria (PGPR) offers a promising approach to enhance plant growth and yield. This study evaluated the effects of PGPR types and application frequencies on the growth and yield of the Grobogan soybean variety. The experiment, conducted from June to September 2025, employed a two-factor Randomized Complete Block Design with five PGPR types and three application frequencies. Results showed that PGPR type significantly affected plant height, leaf number, and pod number, while application frequency significantly influenced plant height at 10 WAP and pod number. Bamboo root PGPR produced the best performance, with a plant height of 78.84 cm, 43 leaves, and 110 pods under three applications. These findings demonstrate that bamboo root PGPR is a promising biological agent for sustainably improving soybean productivity.
