Abstract
The aim of this study was to evaluate the impact of building a vertical garden coupled with a drip irrigation system on the production of yellow onions in a greenhouse. The research emphasized the creation of vertical arrangements, setting up of a drip irrigation system, and the implications of varying stacking intervals and rooting depths on the growth of onions. Except for employing a drip irrigation system, standard procedures for onion cultivation were adhered to. The experiment encompassed three stacking intervals (S10.71 m, S10.56 m and SI0.36 m) and two rooting depths (RD 0.31 m and RD 0.16), with these factors constituting six treatments replicated thrice. Key parameters such as leaf length, leaf count. crop stand, root length, bulb weight, bulb diameter, plant height, quantity of bulbs per crate, and total bulb weight were gauged during the investigation. the Analysis of Variance for Complete Randomized Design (CRD) was utilized to discern significant disparities between the factors across three parameters. Two-way (ANOVA) and Duncan Multiple Range Test (DMRT) were employed to analyze data from each vertical arrangement. Additional notes on pest incidence and shading were taken for potential future reference. The findings disclosed a moderate association between temperature and leaf growth, marked by an R2 value of 0.70. The study showed that both the stacking interval and rooting depth exerted similar effects on the leaf count, which had an average of 4.61 and leaf growth, with a minimal weekly growth average of just 1.47cm, for plan height, the combination of A1B1 resulted in the tallest plants, with a plant height of 39.73 cm, and root lengths exhibited an average length of 3.57 cm. These variables did not demonstrate significant differences. Yet, the stacking intervals of 0.71 m A and 0.51 m distinctly affected the weight and size of the yellow onion bulbs. Average weights were 11.16 for A1 and 4.5 for A2, while average sizes were 7.66 for A1 and 4.65 for A2.
As a result of these observations, it was determined that the construction of vertical arrangements with diverse stacking intervals and rooting depths had minimal impact on onion growth, apart from bulb diameter and bulb weight. temperature was found to be a crucial factor in greenhouse onion farming, exhibiting heat sensitivity during the initial stages up to bulb formation. the presence of shade from nearby trees helped alleviates negative effects.
