Abstract
The cultivation of sesame in organic systems under paddy field conditions is currently limited by data on the appropriate use of organic fertilizers as a replacement for chemical fertilizers. This research aims to investigate the suitable rate of pelletized chicken manure application for sesame production to achieve high seed yields and improve the benefit-cost ratios (BCR). This study was conducted at the Ubon Ratchathani Field Crops Research Center, Ubon Ratchathani Province, during 2022-2023. The experiment was designed using a randomized complete block design (RCBD) with 7 treatments and 3 replications. The treatments included a control without pelletized chicken manure and the applications at rates of 200 400 600 800 1,000 and 1,200 kilogram per rai. In 2024, three fertilizer application methods that provide optimal sesame seed yields and BCR will be selected. Each method will be tested in large-scale organic paddy fields owned by farmers, compared to a control without organic fertilizer application. The results indicated that the application of pelletized chicken manure in each treatment did not result in statistically significant differences in sesame yield or its components. The production cost of sesame ranged from 2,600 to 6,560 baht per rai. Based on the results of this study, the application rate of 600 kilograms of pelletized chicken manure per rai is recommended as the most suitable rate and worth of investment.
