Abstract

Garlic is one of the important horticultural commodities in Indonesia which is widely used its tubers as a cooking and medicinal ingredient. The large number of land conversion activities and competition between horticultural crops in the highlands have led to the development of garlic plants directed to lower land with different environmental conditions. The aim of this research is to study the volume and frequency of watering to length of time to reach heat unit of garlic. The research was carried out in February-May 2020 at the Greenhouse of the Faculty of Agriculture, Brawijaya University in Jatimulyo, Lowokwaru, Malang. The tools used are polybags, hoe, measuring cup, knife, tape measure, leaf area meter, camera, treatment board, stationery, lux meter, alcohol thermometer and thermohigrometer. The materials used are Lumbuh Putih variety, soil, and NPK fertilizer. This research was compiled with Split Plot Design with volume of watering as a main plot: J1: 400 mm / season, J2: 600 mm / season, J3: 800 mm / season, and J4: 1000 mm / season, while the frequency watering as a sub-plot: P1: watering once a day, P2: watering once every 2 days, and P3: watering once every 3 days. Total combination of treatments from the two factors was 12 treatments, each treatment repeated 3 times, so there were 36 experimental plots. Each experimental plot consist of 15 plants so there were 540 plants in total. Data observations were analyzed using the F test. If there is an interaction or effect of the treatment, a further test is carried out using the HSD test at 5% level. The results of J4 and P1 treatments required a longer time to reach the heat unit for each phase of garlic plant growth.

Abstract

Beetroot (Beta vulgaris L.) is a horticultural plant that has many benefits that lie in tubers. Red beets are widely planted in highland areas with loose soil conditions. Currently, the expansion of land for food crops is experiencing problems due to limited productive land. The use of dry land as agricultural land has the main obstacles, namely low soil fertility, low organic matter content, and generally clay and dust-dominated soil. The application of organic matter needs to be added aiming to improve the physical properties of the soil, especially soil texture so that the soil becomes loose so that it does not hinder the tuber development process. The research was carried out from April 2020 to August 2020 at the Agro-Techno Park (ATP) Jatikerto garden. The study used a split-plot design with organic material sources as the main plot, namely B1: goat manure, B2: Azolla compost, B3: UB compost, and the time of application as subplots, namely T1: simultaneously planting, T2: 1 month before planting, and T3 : 2 months before planting. Observational data were analyzed using analysis of variance (Test F), if there was an influence between treatments, further tests were carried out using the Honest Significant Difference (BNJ) test. The results showed that the use of UB compost was better applied 1 month before planting because it produced high tuber weight per harvest plot and was more profitable. Based on the results of farming analysis, the use of UB compost with an application time of 1 month before planting is feasible to cultivate with an R/C reaching 3.67.
