Abstract

Research on breaking seed dormancy in rice is essential for understanding dormancy-breaking methods and their persistence, as dormancy behavior varies among rice varieties. This study aimed to examine the persistence of dormancy and effective dormancy-breaking methods in Oryza sativa L. cv. Sintanur. The research used two seed lots of the Sintanur variety—new and old lots—arranged in a split-plot design with two factors: dormancy-breaking treatments (control, 24-hour hydration, 48-hour hydration, KNO₃ solution, and GA₃) and storage periods (0, 1, 2, 3, and 4 weeks after harvest). The results showed that seeds of the Sintanur rice variety exhibited dormancy with persistence up to 3 weeks. The interaction between dormancy-breaking treatments and storage period significantly affected germination percentage, normal seedling growth, and seedling dry weight. Treatment with 10 ppm GA₃ for 48 hours effectively broke seed dormancy in the Sintanur variety starting from 1 week after harvest.

Abstract

Purwasari Village, Dramaga District, has great potential for sweet potato cultivation, which can open up significant economic opportunities for farmers, but challenges in sustainability and improving production quality are still obstacles. One of the efforts made to overcome this is through integrated agricultural training, which focuses on improving sweet potato cultivation techniques through the IPB Innovation KKN-T program. This activity aims to help farmers understand good crop cultivation practices, Good Agriculture Practice (GAP), and increase the productivity of sweet potato cultivation. The method of implementing the activity is carried out through several stages, namely land processing, planting sweet potato seeds, training, presentation of material, giving pre-tests and post-tests related to Good Agriculture Practice (GAP), and installing 60 × 40 cm land identity signs. The results of this training show an increase in the knowledge of sweet potato farmers by 7%, as measured by the results of the pre-test and post-test, as well as an increase in farmers' participation in cultivating sweet potatoes. The implementation of the training also increased sweet potato production by 30%. This activity also collaborates with IPB's Agribusiness and Technology Park (ATP) as a partner, so that harvested sweet potato products can be further processed, marketed, and sold through the ATP distribution network. This program is expected to contribute significantly to the development of sustainable integrated agriculture, as well as improve the welfare of farmers through wider market access and added value to sweet potato products.

Abstract. Widajati E, Syukur M, Diaguna R, Permatasari OSI, Ritonga AW, Sahid ZD, Pratiwi GR, Hatta ANNL. 2023. Morpho-physiological seed diversity and viability of Indonesian cowpea (Vigna unguiculata). Biodiversitas 24: 5319-5327. Cowpea is a legume with a potential nutritional content almost equivalent to soybeans; it can be developed as a substitute agent for raw materials for food processing. One of the factors in obtaining high cowpea production is to use of quality seeds. Our study aimed to evaluate the performance and morpho-physiological correlations and viability of cowpea seed collections from IPB University Bogor and the Indonesian Research Institute of Legume. We used ten genotypes of cowpea, which had superior seed information. The results showed that the ten cowpea genotypes had superior morpho-physiological and seed viability. The seed germination percentage was categorized as medium-high (>60%). Eight cowpea genotypes were grouped into one major group based on morpho-physiological characteristics and viability. Furthermore, positive correlations were found between the observed variables of seed viability (seed germination, seed growth speed, and seed vigor index). Our research results are useful as a source of genetic diversity for plant breeders in developing new superior varieties in the future. In addition, agronomists can use this information to plant cowpeas based on planting location.
