Abstract

Wahyuni et al, 2019. Dry Land Chemical Characteristics and Soybean Fertilizer Recommendation in Bengkulu Selatan District. pp. 32-36.Land characteristics plays an important role for crop cultivation as the basis needed to determine the soil fertility of agricultural land. Soil fertility is the basis for determining fertilizer recommendations. This objective of this research was to assess the chemical characteristics of South Bengkulu Regency dry land and fertilizer recommendations for soybean cropping. Dry land sampling was taken from South Bengkulu Regency and sample was analyzed at the Bengkulu AIAT Soil Laboratory in 2015. The soil acidity are varied according to the position on the landscape in South Bengkulu Regency from acidic to sour (80% to 20%). Organic content are varied from very low to high level (68 to 4 %). potential K content is very low (100%) and potential P content was varied from very low to low( 96 to 4 %).  Therefore, the appropriate fertilization recommendations should be undertaken to improve soil fertility and yield potential include 1) liming 1-2 tons / ha and using N fertilizer in the form of urea, 2) adding organic matter 2 t / ha, 3) 150 kg KCl fertilizer / ha, and 4) SP-36 fertilizer 200 kg / ha.

Abstract

Yartiwi et al, 2019.The Diversity of New Superior Variety (Vub) of Rice at Rainfed Land in Two Different Seasons in Seluma District, Bengkulu Province. pp. 216-224.The planting season is one of the factors influencing the yield in the cultivation of rice plant, the use of new adaptive superior varieties is one of the technologies to increase the productivity of paddy rice. The purpose of the study was to see the growth viability and the results of several new improved varieties of paddy fields on rainfed land planted in two different planting seasons in Seluma Regency, Bengkulu Province. This study was conducted in Karang Dapo Village, Semidang Alas Maras District, Seluma Regency, from April to December 2017. The assessment was carried out using a Randomized Block Design (RBD) with 2 factors. The first factor is the treatment of variety (V) which consists of 4 levels of treatment. The second factor is the planting season (MT), which consists of 2 levels, resulting in 8 treatment combinations. Each treatment combination was repeated 3 times. Number of plants sample 10 plants / replications. Analysis carried out on quantitative data observations from vegetative and generative growth component variables using the F test at the level of 5%. If there are significant differences between treatments, further testing is carried out with the LSD test at 5% level. The results of the research showed that in the rainy season the production was higher compared to the results in the dry season, seen from the performance of growth and yield obtained by Inpari 39, 41 and Situbagendit varieties which were more adaptive compared to existing varieties.
