Vol. 20 No. 2 (2023): Jurnal Ilmiah Pertanian

Jurnal Ilmiah Pertanian (JIP) is a peer-reviewed, open-access journal that publishes original research articles on agricultural advances and local land resources for global dissemination. It serves as a platform for researchers and academics to share their findings, methodologies, and innovative approaches in agriculture. In this issue, we published nine articles that consist of 3 Short Communications and 6 Research Articles. For the Short Communications: First, the article explores the effectiveness of indigenous Rhizobium sp. isolates obtained from peatland soils in promoting the growth and production of soybean plants. Second, the article focuses on the suppression of Xanthomonas oryzae pv. oryzae, a bacterial pathogen that causes a devastating disease called bacterial blight in rice plants. Thirth, the article investigates the use of covering materials during the acclimatization process of Mucuna bracteata D.C., a legume plant species with significant agricultural potential. The Research Article: first, the article focuses on improving tomato production in dryland environments by applying bio-organo-mineral fertilizers. Second, the article presents a case study conducted in East Java, Indonesia, to explore the relationship between corporate social responsibility (CSR) initiatives and agricultural companies' marketing and financial performance. Thirth is a study that is a cover article in this issue. This study investigates the long-term residual effects of biochar derived from tobacco scraps on red spinach (Amaranthus tricolor) growth in Entisols, a specific type of soil. Fourth, the article focuses on determining the land suitability for sustainable cultivation practices of porang, a plant species known as Amorphophallus oncophyllus L., in Pasuruan Regency, Indonesia. Fifth, the article investigates using biochar and clay to enhance the chemical quality of sandy-textured soil and improve shallot yields. And lastly, the article focuses on assessing the genetic diversity, heritability, and productivity of new sugarcane clones in paddy fields in Indonesia.
