Vol. 17 No. 2 (2021): Jurnal Ilmiah Pertanian

Jurnal Ilmiah Pertanian Volume 17 Issue 2 (2021) features original research articles that examine sustainable crop production, soil–plant interactions, biological inputs, postharvest quality, and agro-industrial waste utilization in tropical agricultural systems. The articles in this issue focus on environmentally sound management practices, particularly the application of organic amendments, biofertilizers, and biological agents to improve crop performance and resource use efficiency. Several contributions investigate crop growth responses under different soil and fertilization regimes. One study evaluates paddy performance in swampland ecosystems using organic pellet fertilizers derived from Azolla and vermicompost, highlighting their role in supporting rice cultivation in marginal environments. Other studies examine celery (Apium graveolens L.) growth in red-yellow podzolic soils inoculated with earthworms (Pontoscolex corethrurus) and maize root development under N, P, and K fertilization monitored through rhizotron observation, providing insights into root dynamics and nutrient availability.

The influence of microbial-based inputs is addressed through research on exopolysaccharide-producing Azotobacter combined with cow manure, which assesses nutrient uptake and root-to-shoot ratio in sorghum. This study emphasizes the contribution of beneficial microorganisms and organic matter to plant nutrient acquisition and biomass allocation. Postharvest management and agro-industrial innovation are also represented in this issue. An investigation of Bulog rice storage piles evaluates their effects on rice weevil (Sitophilus oryzae L.) populations and rice quality during storage in Jayawijaya Regency, offering implications for improving grain storage practices. In addition, an agro-industrial study explores the production of nata de cassava from tapioca wastewater using different natural nitrogen sources, demonstrating the potential of agro-industrial by-products as raw materials for value-added food products.

Together, the articles in Jurnal Ilmiah Pertanian Volume 17 Issue 2 (2021) illustrate the diversity of research approaches addressing soil fertility, crop productivity, postharvest quality, and waste valorization within tropical agriculture.
