Abstract

Background: Global climate change significantly affects carbon dynamics in perennial crop ecosystems, including agroforestry systems. This study aims to analyze carbon dynamics in three types of agroforestry systems: agrosilvopastoral, agrosilvicultural based on horticultural crops, agrosilvicultural based on woody plants, and to identify the diversity and types of vegetation. Methods: The study was conducted from January to March 2025 using field surveys and purposive sampling in Wonosalam, East Java, Indonesia. Laboratory analyses included physical properties (soil texture and bulk density), chemical properties. Results: The regression model showed R2 =0,419 Idicating that 41,9% of soil orgnaik carbon variation is explained by plant biomass carbon stock, highlighting its significant contribution to soil carbon accumulation. Conclusions: The agrosilvicultural system based on woody plants provides the highest contribution to carbon dynamics compared to other types of agroforestry, due to its vegetation composition dominated by woody and perennial plants. The even distribution of the Importance Value Index (IVI) reflects a stable and balanced ecosystem, as observed in plot 3, where excelsa coffee (Coffea excelsa) has an IVI of 37.78%, Durian (Durio zibethinus) has 35.56%, and banana (Musa spp) also has 37.78%.

Abstract

Background: Vigna unguiculata (cowpea) is an important legume crop whose productivity can be affected by foliar diseases, including leaf necrosis caused by fungal pathogens. Identification of fungi associated with necrotic symptoms is essential as baseline information for plant disease management. Methods: This study aimed to identify fungi associated with necrotic lesions on cowpea leaves. Leaf samples showing necrotic symptoms were collected from agricultural fields in Tengger Wetan Village, Kerek Subdistrict, Tuban Regency, East Java. Fungal isolation was performed from infected leaf tissues to obtain pure cultures. Identification was conducted based on macroscopic colony characteristics and microscopic features using slide culture techniques and standard morphological identification keys. Results: Two dominant fungal isolates were consistently associated with necrotic symptoms on cowpea leaves. These fungi were identified morphologically as Alternaria alternata (isolate D1) and Nigrospora sp. (isolate D3). A. alternata was characterized by yellowish-white colonies, hyaline septate hyphae, and dark oval conidia, whereas Nigrospora sp. exhibited cottony white colonies with brown, globose conidia. Both fungi were associated with brown to black necrotic spots on the leaf surface. Conclusions: The findings provide initial information on fungal species associated with leaf necrosis in cowpea based on morphological identification. This information is useful as a foundation for further pathological and molecular studies to confirm species identity and support the development of appropriate disease management strategies.

Abstract

Spodoptera litura pest attacks can cause disturbances in plant growth and lead to considerable yield losses. Control that is often done to control S. litura is usually with chemical insecticides, but excessive use of chemical insecticides has the potential to cause adverse effects on the environment. As a safer and more sustainable alternative, pest control can be done through the utilization of biological agents such as pathogens that function as bioinsecticides, one of which is Nuclear Polyhedrosis Virus (NPV). This research aims to analyze the effect of length of exposure to sunlight and the type of storage container on the effectiveness of NPV in controlling S. litura. NPV isolates were exposed to direct sunlight for 1, 3, 6 hours in glass and plastic vial containers. The isolate was infected to 3rd instar S. litura larvae using feed contamination technique. This research implemented a factorial Completely Randomized Design (CRD), with 6 treatments and control. The results showed that NPV isolates with MK.1 and MP.1 treatments were effective in producing a percentage of larvae mortality and were able to suppress the formation of pupae and imago with a mortality percentage of 84,2 % and 71,4 % at 72 hours after aplication. Length of sunlight exposure affects the effectiveness of NPV isolates.
