Abstract

The research aims to study the effect of a combination of the trellis model and the direction of plant propagation on the growth and yield of long beans. The environmental design used a randomized block design with six treatments, repeated 5 times. The treatment are the trellis models (fence, triangle and para-para) and plant propagation directions (vertical and mixed). Growth variables include plant length, number of leaves, leaf area, and net assimilation rate. Yield variables include pod length, number of pods, pod weight, and yield per hectare. The results of the research showed that the treatment of different models of trellis and the direction of propagation of long bean plants in the mixed propagation direction resulted in higher plant length, leaf area, net assimilation rate, pod length per plant, pod weight per plant and yield per hectare compared to the vertical propagation direction with the model. the same trellis. The para-para trellis model treatment with mixed propagation directions produced a pod length and number of pods per plant of 60.76 cm and 57.59 pods per plant, 19.30% and 14.31% higher than the para-para trellis model with vertical propagation direction. 58.29 cm and 56.05 pods. The treatment of para-para trellis model with mixed creeping directions produced pod weight per plant and yield per hectare of 1.64 kg per plant and 7.3 ton.ha-1, which was 15.49% and 15.37% higher than the para-para trellis model with vertical propagation direction, which produces 1.42 kg per plant and 6.70 tons ha-1.

Abstract

Beetroot is traditionally cultivated in highland areas; however, limited land availability and growing market demand have encouraged its expansion into mid-altitude regions. Thermal unit accumulation is an important factor in predicting crop phenology and harvest time. This study aimed to analyze the thermal unit requirements, growth performance, and tuber quality of beetroot cultivated at different altitudes in East Java, Indonesia. The experiment was conducted from August to December 2024 in greenhouses located in Jatimulyo, Malang (445 m a.s.l., midland) and Sumberejo, Batu (873 m a.s.l., highland) using 250 plants of the Boro variety with a single-plant observation method. Results showed that midland-grown plants reached harvest earlier (84 DAS; 1,527.3 °C·day) compared to highland-grown plants (104 DAS; 1,572.7 °C·day). Higher thermal accumulation had a strong positive correlation with soluble solids (r = 0.74) and a strong negative correlation with fresh tuber weight (r = –0.79), indicating that increased heat enhanced sugar synthesis but reduced biomass. Highland conditions produced larger tubers, while midland conditions improved betacyanin and sweetness levels, showed that altitude-driven temperature differences affect both yield and quality, suggesting that highland cultivation is suitable for fresh markets, whereas midland cultivation is more appropriate for industrial uses such as natural food colorants and processing industries.
