Optimizing Sustainable Dryland Management for the Development of Shallots Through the Application of Good Agricultural Practices

Abstract

Shallot are one of the leading commodities in Central Sulawesi because shallot are the raw material for making fried onion which are widely cultivated by people in the Palu Valley. The development of shallot in Central Sulawesi often faces problems, namely: limited availability of fertile land, implementation of cultivation systems that are not yet optimal because they do not follow good agricultural practice standards for dryland shallot cultivation and pest and disease attacks. The research aims to determine the soil processing system and effective fertilizer dosage as a reference in implementing good agricultural practices for the Palu Valley variety of shallot in dryland. The research was carried out at the shallot planting center in Sigi Regency using a Split Plot Design. The main plot is the height of the bed which consists of 3 levels, namely: S1 = 10 cm, S2 = 20 cm, and S3 = 30 cm. The subplot is the fertilizer dose which consists of 3 levels, namely: P0 = no fertilizer, P1 = inorganic fertilizer according to recommendations, P2 = organic fertilizer according to recommendations. The observation variables are the growth and yield of shallot. The research results showed that the height of the bed and the type of fertilizer applied had a significant effect on the growth and yield of shallot in all parameters except the number of shallot tillers. The 20 cm bed height treatment produced higher fresh weight per plant and yield per hectare compared to other bed heights, while the inorganic fertilizer type produced higher fresh weight per plant and yield per hectare compared to other types of fertilizer but was not significantly different from organic fertilizer.
