Cassava disease detection using a lightweight modified soft attention network

Pest Management Science, Volume 81, Issue 2, Page 607-617, February 2025.
The main framework of the proposed CDDNet approach. Abstract BACKGROUND Cassava is a high‐carbohydrate crop that is at risk of viral infections. The production rate and quality of cassava crops are affected by several diseases. However, the manual identification of diseases is challenging and requires considerable time because of the lack of field ...

Cassava brown streak disease effects on leaf metabolites and pigment accumulation

African Crop Science Journal, 2017
Cassava Brown Streak Disease (CBSD) is a threat to productivity and product quality in East Africa. The objective of this study was to understand the effect of CBSD on the primary photosynthetic apparatus of cassava (Manihot esculenta Crantz). Three cassava varieties with varying levels of reaction to infection by CBSD were chosen and subjected to ...

Assessment of genetic diversity and heterotic alignment of CIMMYT and IITA maize inbred lines adapted to sub‐Saharan Africa

Crop Science, Volume 65, Issue 1, January/February 2025.
Abstract Despite the breeding efforts by many institutions, maize (Zea mays L.) productivity in sub‐Saharan Africa is still low. A limited number of productive maize hybrids have been developed partly due to a lack of knowledge on the diversity and heterotic relationship of the germplasm, especially in public breeding programs. Understanding the extent

A Blueprint for Building Resilience and Food Security in MENA and SSA Drylands: Diversifying Agriculture With Neglected and Underutilized Species

Food and Energy Security, Volume 14, Issue 1, January/February 2025.
ABSTRACT Drylands, encompassing 41% of global land and supporting over 2 billion people, face significant challenges, including water scarcity, extreme temperatures, and soil degradation. Dryland spans vast areas of Middle East and North Africa (MENA) and Sub‐Sahara Africa (SSA) regions and poses a threat to food security and resilience.
