Abstract

Black pepper (Piper nigrum L.), the king of spice, holds high economic value as it is one of the most important and widely consumed spices in the world. The aim of this study is (1) to study the relationship between prevalence of root knot nematode and the soil properties; (2) to study the potential of black pepper rootstock cultivation in hydroponics; and (3) to characterize of black peppers growth in fully aerated hydroponics. At Ladang Samarakan, 10 completely random soil sampling points were done for each of the vatieties of black peppers plants (panniyur-1, Kuching, and Semongok Emas). Then, for each variety of the black pepper plants at Ladang Samarakan, 10 randomly selected black pepper plants were selected for survey of prevalence of root knot nematodes. There was 60% of Semongok Emas black peppers that was infected with root knot nematode compared to the 10% of Kuching and 10% of Panniyur-1 at Ladang Samarakan. Semongok Emas black peppers soil temperature was the lowest with 27.3 = 0.945 C while Panniyur-1 with 28.7 = 0.879 C and Kuching with the highest temperature of 29.5 = 1.089 C. There was a negative correlation between soil temperature and the prevalence of root knot nematodes in black pepper plants at Ladang Samarakan at p 0.025 < 0.05. Then, potential environment for setting up hydroponics for black pepper rootstock cultivation was designed based on the aeration in the hydroponics (non-aerated, half-aerated and fully aerated). Fully aerated black pepper hydroponics shown 100% of survival and rooting with 75% of sprouting of black peppers. As for non-aerated and half aerated black pepper hydroponics, the black pepper cuttings could not grow and survive throughout the 12 weeks study period. The growth of black pepper cuttings in fully aerated hydroponics is recorded, showing 6.0 = 4.60 cm increase in stem length, 24.28 = 3.10 cm increase in longest roots and 2.8 = 1.2 total number of leaves throughout the 12 weeks study period. In conclusion, the was negative correlation between soil temperature and prevalence of root knot nematode at Ladang Samarakan and potential of growing black peppers in hydroponics.
