GROWTH OF CARROTS (DAUCUS CAROTA VARI. KURODA) SUPPLIED WITH DIFFERENT LEVELS OF KAPPAPHYCUS ALVAREZII DRIPPINGS DELIVERED THROUGH SUBSURFACE DRIP IRRIGATION UNDER GRENNHOUSE STRUCTURE

The study was conducted at RTC-Korea-Philippines Vocational Training Center Davao, Buhisan, Tibungco, Davao City from March to May 2017 to determine the growth performance of carrots in terms of number of leaves and leaf stalks as supplied with different levels of Kappaphycus alvarezii drippings at 10 ml, 20 ml, and 30 ml per liter of water. Data were statistically analyzed through Randomized Complete Block Design (RCBD) with five (5) treatments replicated three (3) times. The treatments include pure water (T1), a nutrient solution of 10 ml of Kappaphycus alvarezii drippings per liter of water (T2), a 20 ml Kappaphycus alvarezii drippings per liter of water (T3), a 40 ml Kappaphycus alvarezii drippings per liter of water (T4), and a concentration of water and commercial organic foliar fertilizer (T5). Results showed that the application of Kappaphycus alvarezii drippings through subsurface drip irrigation improved the vegetative growth of carrot in terms of the leaf stalk and leaf count at 30, 37, and 45 days after sowing, under greenhouse structure.
