Application of drip irrigation on broccoli plants (Brassica oleracea var. Italica) with soil media and sand using a polybag

Abstract

Broccoli (Brassica oleracea var. italica) is a type of vegetable plant belonging to the cabbage family (Brassicaceae). One way to improve broccoli cultivation technology is to use a water-saving irrigation system (drip irrigation). The aim of this research is to conduct trials on a drip irrigation system and analyze the need and productivity of irrigation water for broccoli plants using soil and sand using polybags. The research method used was an experimental method of plant growth period with experiments on land using surface drip irrigation and AB Mix fertilizer. The experiment was carried out using an automatic tap to withstand the high pressure in the connecting water container and emitter hole with modifications using a 7 mm hose and a stick driver as a plug. The parameters observed were water discharge, emitter uniformity, plant water requirements, broccoli plant growth. The results showed that the growth of Broccoli plants seen from the total average number of leaves on the 30th day was 9.17 pieces on soil media and 8.83 pieces on sand media, plant height on the 30th day was 12.07 cm on soil media and 11 cm on sand media, the average emitter uniformity is 80%, the average water discharge is 1833.33 ml, the total water use is 191.5 liters, the total water requirement is 0.7418 liters/day in the early planting phase and in the middle phase obtained was 0.5960 liters/day.
