Effect of the Cultivation Systems and Split Fertilizer Applications on the Growth and Yields of Tatsoi (Brassica rapa subsp. narinosa)

Tatsoi [Brassica rapa subsp. narinosa (L.H.Bailey) Hanelt] is a leafy vegetable with potential for cultivation in riparian wetland ecosystem. The floating culture system has the advantage of ensuring sufficient water supply growing substrate due to continuous upward movement caused by capillarity force. This study evaluated responses tatsoi plant split fertilizer applications under conventional and systems. treatments consisted control (F0), single (F1), into 2 (F2), 3 (F3) or 4 (F4). results showed that early growth was better using than system. However, adapted well systems as long nutrients were available. A application 6 g NPK (16:16:16 v/v/v) at transplanting provided nutrients, indicated number leaves, total leaf area, canopy stem dry weight, weight harvest. SPAD values plants higher 14 20 DAT fertilized 4-split application. Transplanting occurred days after seed planting (DAP), harvest 49 later. quadratic regression model length (L), width (W), L×W predictors reliable non-destructive area estimation plant. It recommended farmers apply rate g/plant achieve an optimum yield cultivated system.
 HIGHLIGHTS
