Abstract

The corn farmer households examined in this study participated in the dryland transmigration program to enhance welfare by furnishing livelihood capital to poor farmer households. This research compares the livelihood capital of corn farmer households in the transmigration areas of Gorontalo and Boalemo districts, Gorontalo, Indonesia, and examines its impact on their livelihood strategy selection. The study involved 240 poor corn farmer households. Data analysis was conducted by computing the livelihood capital index through entropy weighting analysis, followed by multinomial logistic regression analysis to examine the influence of livelihood capital on livelihood strategies. Findings indicate a higher level of livelihood capital in Boalemo Regency than in Gorontalo Regency, with Boalemo District outperforming in physical and human capital. In contrast, the Gorontalo district excels in natural and social capital. However, the financial capital of corn farmer households in both regions still needs to be improved. Natural and human capital significantly influences the likelihood of corn farming households opting for on-farm strategies over a combination of on-farm and off-farm strategies. In the case of on-farm and off-farm strategies, natural capital substantially enhances the probability of corn farmer households selecting both on-farm and off-farm strategies rather than solely on-farm and non-farm strategies. Conversely, physical capital diminishes the likelihood of corn farmer households adopting both on-farm and off-farm strategies compared to the combination of on-farm and non-farm strategies.

Abstract

Sorghum is one of the cereal crops currently being widely developed as an alternative food in Indonesia. One of the approaches is through research in the field of plant breeding. To initiate the development of more advanced research, with future research focused on developing local cultivars as part of local wisdom that preserves sustainability and genetic diversity, information is needed regarding the phenological characteristics and growth phases of sorghum plants as conducted in this study. The plant materials used were two local sorghum genotypes of East Sumba, namely Watar Hammu Manippa Tadda and Watar Hammu Mitting Nggangga. A descriptive research method was used to provide a detailed description of the characteristics of sorghum plants. The research was conducted from June to December 2024 at the Science Techno Park (STP), Faculty of Agriculture and Business, Satya Wacana Christian University, Wates Village, Getasan District, Semarang Regency, at an altitude of 1118 meters above sea level. The results showed that the local East Sumba sorghum genotypes, Watar Hammu Manippa Tadda and genotype Watar Hammu Mitting Nggangga, have similar phenological charactersistics in terms of leaf, stem, and root, while their seed characteristics and panicle shapes of the two types are different, with clear distinctions in seed and panicle morphology serving as important differentiating traits. Based on the growth phase, there are no significant differences between the two genotypes. The research results indicates that both genotypes have strong potential as breeding materials, with breeding efforts best directed toward combining the superior traits of each genotype, maintaining local adaptation while improving seed productivity and quality. This study provides detailed information on the phenological characteristics and growth phases of two local sorghum varieties from East Sumba. Information related to plant phenology is an important foundation for developing sorghum breeding research in Indonesia. Knowing the characteristics of the plant also supports the optimal use of sorghum as a food source or alternative feed.

Abstract

Several wheat genotypes collected by the International Maize and Wheat Improvement Center (CIMMYT) in Mexico can be introduced in the tropical regions of Indonesia to support national wheat production. Currently, four genotypes originating worldwide are available for introduction: CWI 10553, CWI 17903, CWI 89948, and CWI 8124. This research aims to identify the performance and yield of these genotypes grown in a controlled environment. Wheat seeds were cultured in MS medium then transplanted into a pot filled with mixture of soil and compost. Pot cultivation was carried out at a latitude of 800 m asl. Fertilizer was applied four times: 1) 2 g of guano during transplanting; 2) 2 g of guano + 1 g of urea + 1 g of ZA + 2 g of P2O5 + 1 g of KCl  three weeks after transplanting, 3) 2 g of guano 6 weeks after planting, and 4) 1 g of urea + 1 g of ZA + 2 g of P2O5 + 1 g of KCl during grain filling. By the end of the growing season, 10 plants of CWI 10553, 2 plants of CWI 17903, 4 plants of CWI 89948, and 10 plants of CWI 8124 survived until grain production. CWI 8124 seemed to adapt well as indicated by its relatively high number of tillers, number of seeds per spike, and grain weight per plant. CWI 89948 was less adaptive as its height and productivity were relatively low. Generally speaking, two genotypes in the Semarang Regency of Central Java suggested for further study were CWI 8124 and CWI 10553.
