Pengaruh Keragaman Tanaman Sela pada Tanaman Kubis Bunga (Brassica oleracea var. botrytis L.) terhadap Pertumbuhan dan Hasil dalam Sistem Rooftop Garden

Urban Farm DB summary

A field trial on the sixth-floor rooftop of the central building at the Faculty of Agriculture, Universitas Brawijaya, Malang, Indonesia, conducted from December 2019 to March 2020, tested the effect of intercropping on cauliflower (Brassica oleracea var. botrytis) growth and yield in a rooftop garden system. Using a randomized block design with six treatments and four replications, intercropping reduced cauliflower's growth and yield parameters but raised the land equivalent ratio (LER) above 1, except when intercropped with pakcoy or water spinach; LER reached 1.74 with sweet corn, 1.57 with upright common beans, and 1.27 with broccoli.
