The activities of Young Farmers doing a horticulture business do not always run smoothly, there are some challenges of it. This is one of the risks that must be faced by young farmers in Sumba. Recently, the price of horticulture products in September and October has decreased and many farmers feel hopeless about this condition. Besides the price problem, at the end of the dry season and the beginning of the rainy season, the level of pest and disease attacks is quite high and caused crops failure among horticulture farmers.

Based on the problem above, the MultiplicationProgram of Stube HEMAT in Sumba provides an activity with the theme ‘overproduction of horticulture product at the end of 2021 and the effect on price fluctuation’ and the second theme was 'Climate change and challenges of horticulture cultivation during the rainy season'.

This activity was carried out in Lambanapu, at the study center of horticulture agriculture (Saturday, 04/12/2021). The participants consisted of students, church youth, young farmers, and some senior farmers. The atmosphere in this training was quite lively because new participants were more active in asking questions than those who had attended the previous training sessions.

In this training, Elias Taemnanu, the speaker, gave an affirmation to pay attention to the rotation of plants in one season. This is done so that the rate of pest and disease attacks is reduced and this method can break the chain of pest and disease growth. In addition, farmers must also have a planting season calendar and a market calendar. It helps farmers to avoid the overproduction of horticulture products and the declining prices of horticulture products. Then, the farmers should keep their motivation to learn from experience and develop the up-dated agriculture knowledge, by applying agricultural innovations in order to achieve maximum and qualified production.***
