Effect of the Different Cultivation Systems on the Growth Yield and Quality of Muskmelon
S. R. Yang
An experiment was carried out in the soil texture of sandy-loam at An-Nan, Tainan City to study the effect of the different cultivating system on the growth, maturity, productivity and quality of muskmelon. cv. No. 8 Tainan. The cultivating systems were adopted as follows: (a) Plots mulched with rice straw; (b) Plots mulched with rice straw and planted corns as windbreak; (c) Plots mulched with black polyethylene film and planted corns as windbreak; (d) Plots covered with 0.15 mm thick transparent polyethylene plastic tunnel (0.8m high); (e) Plots covered with 0.15 mm thick transparent polyethylene plastic tunnel (2.5m high). The results showed that the mean min.-max. temperatures were 2~9℃ and 1.6~4.4℃higher, respectively in (d) and (e) than other systems. The growth rate was highest in (d), followed by (e) and lowest in (b). The days from planting to harvesting were 9.2~13.9 days earlier (16~26 days earlier in 1st harvesting date) in plastic tunnels then other systems. The highest yield, produced by (e), were 4.7, 26.7, 37.8 and 50.2% higher, respectively than those obtained by (d), (c), (b) and (a). The sugar content were greatest (14.1 & 14 oBrix, respectively) in (e) and (d), followed by (a) and (c) and lowest by (b). The least percentage of fruit cracking (1.5%), obtained by (d), were 3.7, 8.9, 16.9 and 18.9% less, respectively than those obtained by (e), (c), (b) and (a).
