Response of Potato Growth And Yield On First Generation (G1) In Various Planting Media Compositions

Abstract

Potato is a horticultural commodity that contains carbohydrates, protein and other nutrients. Potatoes have the potential to be developed to support diversification and food security programs. This research aims to find out the suitable planting media, so that it can overcome the limitations and provide quality potato seeds. The research was conducted in March- August 2024 in Alahan Panjang, Solok. The treatments were several compositions of cocofiber (CF) and cocopeat (CP) planting media arranged in a completely randomized design with 6 treatments and 4 replications, namely the composition; CF 100%, CP 100%, CF 20%+CP 80%, CF 40%+CP 60%, CF 60%+CP 40%, and CF 80%+CP 20%. The data obtained were statistically analyzed using the F test and DNMRT further test at the 5% level. The results showed that in general the use of 100% cocopeat plant media was the best composition, while Cocopeat 80% + Cocofiber 20%, gave the best growth of plant height, number of leaves, stem diameter and number of branches
