Abstract

Drought stress caused by limited water supply in the root zone can inhibit plant growth. Foxtail millet (Setaria italica L. Beauv) is an alternative carbohydrate source known for its drought tolerance and ease of cultivation. Biofertilizers based on Trichoderma sp. can serve as biological agents that promote plant growth under abiotic stress conditions, including drought. This study aimed to evaluate the effect of Trichoderma sp. application on growth and yield of foxtail millet under drought stress conditions. This study was conducted at the Munjuljaya Experimental Field, Purwakarta Regency, using a factorial Randomized Block Design (RBD) with three replications. The first factor was Trichoderma sp. dosage with four levels: T0 (0 g), T1 (20 g), T2 (40 g), and T3 (60 g). The second factor was drought stress with three levels: C1 (25% field capacity), C2 (50% field capacity), and C3 (75% field capacity). In total, 30 experimental units were tested. The results showed that Trichoderma sp. application and water treatment did not significantly affect plant height, tiller number, leaf chlorophyll index, panicle length, panicle weight, fresh root weight, root length, 1000-seed weight, and shoot-root ratio. However, the highest dosage of Trichoderma sp. improved several growth parameters, such as plant height in T3 (60 g) with 78.13 cm, panicle length in T3 (60 g) with 8.77 cm, fresh root weight at 81 DAP (days after planting) in T3 (60 g) with 6.88 g, and the highest shoot-root ratio in T3 (60 g) with 3.35. This study has an impact on the growth and yield of millet because Trichoderma sp. plays a role in root growth and plant nutrient absorption.

Abstract

The growth of bok choy (Brassica rapa L. var. chinensis) is affected by the type and composition of growing media. This study evaluated the growth response of pakcoy to five media combinations: P1: Soil + Rice Husk Charcoal (2:1), P2: Soil + Rice Husk Charcoal + Cow Manure Compost (2:1:1), P3: Soil + Rice Husk Charcoal + Cocopeat (2:1:1), P4: Soil + Rice Husk Charcoal + Vermicompost (2:1:1), and P5: Soil + Cow Manure Compost + Vermiculite + Malang Sand (2:1:1:1). Growth was assessed based on plant height, leaf number, root length, shoot fresh weight, and root fresh weight. The data were subjected to analysis of variance (ANOVA), followed by Duncan’s Multiple Range Test (DMRT) at a 5% significance level (α = 0.05). The results indicated that media composition significantly affected all growth parameters. Among the treatments, P4 produced the most favorable growth response, recording a plant height of 22.33 cm, 12 leaves, a root length of 50.83 cm, a shoot fresh weight of 31.00 g, and a root fresh weight of 25.42 g. Higher growth observed under P4 was likely associated with the role of rice husk charcoal through improved aeration and porosity, while vermicompost supplied essential nutrients and enhanced beneficial microbial activity, thereby creating more favorable growing conditions for bok choy compared with the other treatments.
