Abstract

Decline in Arabica coffee productivity in the Kintamani highlands indicates agronomic constraints affecting the plant's reproductive phase. Pruning and the application of growth regulators are two essential approaches to improving the physiological balance that supports flower and fruit formation. This study aims to assess the effectiveness of pruning and Atonik application in promoting shoot, leaf, flower, and fruit-bud growth in Arabica coffee plants. The study was conducted over 12 weeks using a factorial design with a combination of pruning treatments and several Atonik dosage levels. Data were analysed using ANOVA and follow-up tests to determine the differences between treatments. The results showed that pruning consistently increased shoot regeneration and improved canopy structure, thereby optimising light capture efficiency and photosynthetic product distribution. The Atonik application strengthened the plants' physiological response by increasing meristem activity and nutrient absorption. The combination of both treatments produced the highest number of flowers and fruit buds compared to either treatment alone. Scientifically, these findings indicate that the enhancement of the generative phase is highly dependent on vegetative conditions, which are strengthened by canopy management and hormonal stimulation. This study makes an essential contribution to the development of coffee cultivation strategies that integrate pruning practices and hormone regulation to sustainably increase productivity.

Abstract

Microgreens are young vegetable seedlings valued for their high nutritional content and rapid growth cycle. Pakcoy microgreens (Brassica rapa chinensis L.) have strong potential for sustainable urban agriculture. This study aimed to evaluate the effects of different eco-enzyme concentrations and growing media on the growth performance of pakcoy microgreens. The experiment was conducted using a factorial completely randomized design with two factors: eco-enzyme concentration and growing media type. Several growth parameters were observed, including plant height, number of leaves, fresh weight, and overall growth vigor. The results showed that both eco-enzyme concentration and growing media not  significantly influenced the growth of pakcoy microgreens. Higher eco-enzyme concentrations generally promoted better vegetative growth, particularly when combined with suitable growing media. The interaction between eco-enzyme application and growing media played an important role in optimizing microgreen growth performance. These findings indicate that eco-enzyme can be utilized as an environmentally friendly input to enhance pakcoy microgreen production. The use of appropriate growing media further improves growth outcomes, supporting sustainable and efficient microgreen cultivation systems. This study provides practical insights for small-scale growers and urban farmers seeking to improve microgreen productivity using eco-friendly alternatives.
