Control manual for the major disease and pest on pepper(Capsicum annuum L.) cultivated under rain shelter greenhouse was set in this experiment. Preventive and control techniques developed so far against powdery mildew, viral disease , aphids, tabacco budworm, mites and Bemisia tabaci were applied on rain shelter greenhouse located in Cheongwon for environment-friendly agriculture and GAP(Good Agricultural Producton) and Goesan for GAP, and their effects were investigated. For GAP, control system consisting of a total 10 times of chemical spray was established using preventive spray of fungicide against powdery mildew, removal of pepper plant infected by virus and chemical control of aphids which is intermediated host from early stage against viral disease caused mainly by CMV BBWV, and spray of pesticides which could be simultaneously applied to two or more kinds of pests. Using this method, occurrence of all the disease and pest was little or very low despite less spraying time than conventional method.
Control efficacy using the environment-friendly materials announced officially against powdery mildew and pests on pepper for environment-friendly agriculture was influenced by the amount and time treated. Environment-friendly materials should be sprayed preventively with a sufficient amount for a effective control.
Pepper is one of heavy nutrient feeders that need large amounts of nutrients to produce high quality crops. When farmers cultivate peppers in plastic film house, soils in the specific field may have salt accumulation under heavy applications of various fertilizers, which cause several problems associated with consecutive pepper cultivation. Therefore, this study was to investigate red pepper productivity and soil properties as affected by different intervals of side-dress N and K applications. All plots were applied with compost of 2 Mg 10a^-1 and phosphorus of 8.3 kg 10a^-1 as P2O5 for basal dressing. Nitrogen and Potassium fertilizers were treated for side-dressing at different intervals, 22 times in every 10 days(Plot 1), 15 times in every 15 days(Plot 2), and 11 times in every 20 days(Plot 3). The total amounts of fertilizers applied as N-K₂O were 24.6-13.1 kg 10a^-1. In control plot(Plot 4), 60% of total amount of N fertilizer(24.6 kg 10a^-1) and 50% of total K amount(13.1 kg 10a^-1) were applied for basal-dressing, the rest amounts of both fertilizers were applied for side-dressing in three separate times. When selected soil properties at pepper harvesting time were compared with those before transplanting peppers, electrical conductivity(EC) decreased in all the plots, but decrease rate of EC values was lowest in the Plot 4(control). The contents of available phosphorus and exchangeable K⁺ increased whereas exchangeable Ca²⁺ content decreased in all the plots. However, amount of pepper harvested was the highest in the Plot 2 and amount of red pepper yield was 3,764 FW kg 10a^-1 in the Plot. Low quality red pepper in the Plot 2 was 5.35% of total yields, which was the lowest amount among the plots. In addition, red pepper productivity(dry-weight basis) increased by 29.1% in the Plot 2 as compared to that in the control Plot 4.
This study was conducted to investigate the effects of organic matter treatment at the before planting and late harvest cultivative technology to raise crop applications on the yield of red pepper in rain shelter.
Soil moisture change rate in this treatment plot were 5.1 and 15.2 percent. Soil moisture of expanded chaff treatment plot was lower than that of compost to the soil. There' s not much difference in Electrical conductivity (EC) and soil temperture between the treatment plots. EC of expanded chaff application was lower than that of compost to the soil.
The plant height of the pepper in this treatment plot was 167.1 and 216.7cm, stem width was 15.8 and 21.0㎜, number of branching was 20.5 and 24.1. The fruit length change rate of late harvest time has by 21.6 and 22.6 percent, fruit width has 24.1 and 28.4 percent, fruit weight has 37.8 and 45.1 percent. Espesially fruit weigh of expanded chaff application was 2.2 and 8.5 percent lower than that of compost treatment. The yield of red pepper was increase by 151.2 percent with the application of expanded chaff and compost At harvest time, soil pH show a increased but electrical conductivity, organic matter, P₂O₅, K, Ca, Mg and Na show a decrease.
The last harvest time, yield was increase by 143.5 percent with the application of KH₂PO₄. Red pepper harvesting rates of last time was the highest by 72.3 percent w ith the treatment of stopping irrigation and digging root. Harvested unripe fruit was effective at color promotion in soakage application with 0.1 percent ethrel solution at the treating 25℃ for 3 days.
