Abstract

Grape (Vitis vinifera L.) var. Prabu Bestari is an important fruit commodity, but information regarding its reproductive phenology is still minimal. This qualitative descriptive study aimed to determine the time periods required for key phenological stages, namely bud burst, bloom, fruit set, and fruit ripening (harvest), which are crucial for breeding and optimizing production. The research was conducted at the Faculty of Agriculture's Experimental Garden (0–9 masl). The observations revealed a rapid reproductive growth cycle. The average time from pruning to shoot emergence (bud burst) was 7 days after pruning (dap). The phase from bud burst to flowering lasted 18–19 days. Full bloom was very brief, lasting only 1 day, and the phase from flowering to fruit set required 1–3 days. The longest period was from fruit set to harvest, lasting 48 days. Overall, the cycle from pruning to harvest for the Prabu Bestari variety required an average of 120 dap. This phenological data provides an essential basis for effective cultivation management.

Abstract

This study aimed to evaluate the effect of watering frequency on the growth, productivity, and agribusiness feasibility of the Bali Karet shallot variety cultivated in lowland areas. The experiment was conducted at the Experimental Farm of the Faculty of Agriculture, Udayana University, from January to March 2026 using a Randomized Complete Block Design (RCBD) with four irrigation treatments: P0 (once/day), P1 (twice/day), P2 (three times/day), and P3 (soil moisture-based), each with three replications. Data were analyzed using Analysis of Variance (ANOVA) followed by Duncan's Multiple Range Test (DMRT) at the 5% significance level. Watering frequency significantly affected plant growth, productivity, water use, and agribusiness feasibility. Treatment P3 showed the best performance, increasing productivity from 7.8 to 11.3 t ha⁻¹ (44.9%), farm profit from IDR 17.4 million to IDR 42.6 million ha⁻¹ (144.8%), and the R/C ratio from 1.39 to 1.89, while reducing water consumption from 5,850 to 5,100 m³ ha⁻¹ (12.8%) compared with P0. These results demonstrate that soil moisture-based irrigation improves water-use efficiency while maximizing shallot productivity and profitability, making it a promising irrigation strategy for sustainable shallot production in lowland areas.
