producing organic fertilizers and bio-fertilizers, vetiver of Songkhla 3 variety and dolomite.

Moreover, the guideline obtained from learning, observance, trial and errors has been implemented
and developed in the 0.04 ha planting vegetables. Previously, the mentioned area was characterized

by soil with soil fertility deficiencies and giving low yields due to the problem of soil degradation.
The soil texture was sandy clay loam consisting of saline soil a little bit. Moisture in the soil was

very low in the dry season. Moreover, the area was outside the irrigation zone. Therefore, an idea
came up with developing occupations for farmers in the community located at Moo 5, Ban Kok

Phrom, Non Thai sub-district, Non Thai district to implement knowledge regarding integrated

utilization of areas with saline soil in the organic agriculture system whereby agencies from Land
Development Department provide knowledge in analyzing soil and improving soil prior to

cultivation area preparation. The wisdom of farmers themselves is used together with the

technology of Land Development Department, namely dolomite application for pH value
adjustment and killing germs affecting growth of chili peppers together with applying manure to

increase organic matter to the soil. Fermented bio-extracts have microbes which help stimulate the
root system. Regarding moisture storage in the plot where chilies are planted, the drip irrigation

technology system has been installed. The soil is covered with straw and vetiver is used to restore
soil conditions. The objective is to do this as a prototype in building incomes for the community

further.

After soil amendment, the soil has a better structure and has become friable and suitable

for planting chili peppers by selecting the Amphawa Gold according to the demand of the market.

Moreover, regarding intercropping, parsley is also inserted to be planted between plots, resulting
in using water efficiently and worthily. Average yields of chili spur peppers account for 400

kilograms per 400 square meters throughout the age at 180 days. The harvesting price is 2.47 USD
2
per kg and yields of parsley account for 108 kilograms per 400 m (byproducts from watering chili
pepper trees) based on harvesting yields for 1 generation per round of chili pepper production.
