| Abstract:
The study on the production situation and environmental effects on fruit and capsaicin yield in pepper at Nakhon Sawan, Sukhothai and Tak provinces was conducted between September 2005 and August 2006. All 101 pepper farmers were interviewed. The average age of farmers was 45 years, primary education, 4 persons per household, owning 4.3 ha of agricultural land, 2 working persons per household. Income and debt in 2005 were US$4,064 and US$2,688. The pepper planting area was 1 ha/family. The experience of pepper planting was 7 years. Commercial pepper cultivars were 58% local and 42% hybrid cultivars. Pepper production in Tak Province were of 'Num Khieo', 'Prik Man', 'Prik Kariang' cultivars. The T2, T6, T7, T3 and T1 lines of Tak province contained 91,003, 87,521, 83,374, 79,185 and 39,384 Scoville heat unit (SHU) of capsaicinoids. Nakhon Sawan Province planted 'Chinda' and hybrid cultivars while Sukhothai Province planted 'Prik Man', 'Prik Yai' and hybrid cultivars. Main diseases were anthracnose and wilt and main insects were thrips, mites and aphids. Yield averaged 17.3 tons/ha with average prices for fresh and dry products at US$0.38 and US$1.6 per kg. The environment did not affect capsaicinoids yield. | |
