Abstract

Numerous initiatives were carried out to enhance rice production in swampy areas, which required the implementation of suitable technology. The use of adaptive variety, soil, and water management have been reported as the main keys to agricultural culture on tidal swamps. Therefore, this study was conducted to analyze the effect of several levels of substance peat humic application on the growth and yield of rice in tidal swamps. A completely randomized design was also used with two factors and four replications between March to June 2022, in Karya Bakti, Rantau Rasau sub-district of Tanjabtim District, Jambi Province. The first factor was varieties IR-64 and Inpara-4, while the second was the use of humic substance in peat consisting of 0 g/plant, 0.04 g/plant, 0.08 g/plant, and 0.12 g/plant. The cultivation process included the planting of paddy seeds within buckets containing 10 kg of soil. The result showed that the optimal yield of rice varieties IR-64 and Inpara-4, when subjected to peat humic substance in saturated soil culture, was achieved at 0.12 g/plant. This was substantiated by the enhanced uptake of essential nutrients such as N, P, and K in the plants, resulting in superior plant biomass compared to other concentration levels.

Abstract

Lebong including rice-producing areas, but this commodity is mostly newly cultivated one plant in one year. The purpose of this study was to develop a strategy for increasing the rice cropping index (CI) in Lebong Regency. This research was conducted in the month of January 2019 s / d February 2019 by the method of FGD and interviews with the Department of Agriculture, extension workers, farmers, village heads and Babinsa . The activities of research to identify the internal factors (strengths and weaknesses) and external factors (opportunities and threats) being done with SWOT analysis method. Research results obtained factor major internal and external power factor in the form of program/policy of local government in improving the CI rice in Lebong, a factor of weakness is capacity extension of the weak, chance factor is technological innovation to increase the productivity of rice plants and factors threaten is culture farmers which believe that rat pests cannot be controlled. The strategy formulation is done by utilizing the power factor to avoid threats with maximize the performance of extension workers and village through instruction Regent, and make technological innovation pilot rice cultivation on a large scale in an overlay.
