Growth and yield of eight accessions of sweet potato in peat land

Abstract

Sweet potatoes (Ipomoea batatas L.) is a plant that is included in the secondary crop type. Sweet potatoes have high productivity and are profitable and their potential use is quite broad and has the potential to be developed on peatlands. The varieties of several sweet potatoes accessions found and planted by farmers in the cities of Pontianak and Rasau Jaya are still unknown and it is not yet known which types of sweet potatoes accessions have good potential if planted on peat land. This research aims to determine the diversity of growth and yield of eight accessions of sweet potato plants on peat soil and to find out which sweet potato accessions provide the best growth and yield on peat soil. This research was carried out for 4 months. The method used in the research was a Randomized Block Design (RAK) which consisted of 8 treatments of sweet potatoes accessions and was repeated 3 times. The treatments for the eight accessions referred to in the study were ARF 01, ARF 02, ARF 03, ARF 05, ARF 06, ARF 08, ARF 09 dan ARF 10. The variables involved Observed in the study included: length of the main vine , number of branches, fresh weight of the top of the plant, number of tubers per plant, tuber diameter, tuber length  and tuber weight per plants. The results showed that there was diversity in the growth and yield of eight accessions of sweet potato on peat soil. Descriptively, for the growth variable, ARF 08 produces the longest main vine length, ARF 09 produces the highest number of branches, and the ARF 06 accession produces the largest fresh weight of the top of the plant. Meanwhile, the yield variable ARF 03 produced the highest number of tubers per plant, the largest tuber diameter, the largest tuber weight per plant, and the longest tuber length yield was produced by the ARF 10 accession.
