The rapidly increasing population growth in sub-Saharan Africa (SSA), disruptions in the fertilizer supply chain due to the COVID-19 pandemic, and recent geopolitical tensions have highlighted the need for immediate actions toward optimizing fertilizer nutrients use. Fertilizer recommendations in SSA are either pan-territorial, obsolete, having been developed in the 1970s or 1980s, or completely nonexistent...

Introducción La dependencia global de los plaguicidas químicos es profunda, aunque pueden incrementar la producción agrícola, su uso excesivo o inadecuado tiene consecuencias negativas, como la contaminación del suelo y agua, y riesgos a la salud humana. Para contrarrestar estos efectos, los insecticidas biorracionales (derivados vegetales y microbianos) constituyen una alternativa promisoria. Objetivo Realizar un...

This study investigated how Leucaena leucocephala, a dry forest plant, copes with soil copper and herbivory caused by Schistocerca piceifrons, crucial for understanding species adaptation in stressed environments. A 33-day factorial experiment with three copper and two herbivory treatments assessed seedling growth rates (relative growth rate of biomass—RGRB, and leaf area—RGRLA), morphology, net assimilation rate...

In recent years, nitrate leaching and environmental impacts from agriculture have become global issues, due in part to the increased use of nitrogen (N) fertilizers in agriculture. In the Yucatan Peninsula, intercropping is a traditional farming practice known as the “Milpa” system (i.e., a traditional farming practice characterized by the simultaneous cultivation of maize [Zea...

Crop yield response to secondary nutrient sulfur (S) and micronutrient zinc (Zn) has been extensively studied, yet inconsistent results and a lack of context-specific guidelines limit widespread adoption. We conducted a meta-analysis of 152 data points from 27 studies to quantify the impact of S and Zn separately and in combination on maize, rice, and...

Vigna unguiculata L. and Phaseolus lunatus L. are legume species of great importance in Mexico’s low-input systems such as Milpa. In these production systems both species are attacked by pests, such as Diabrotica spp. that reduce their yield and farmers do not have the supplies for timely pest management. The objective of this study was...

In response to global concerns over food scarcity, the sweet potato (Ipomoea batatas (L.) Lam) has emerged as a promising alternative due to its rich composition of carbohydrates (starch), protein, fiber, vitamins, and minerals. This study aims to assess the physicochemical characteristics and nutritional content of different sweet potato landraces cultivated in Yucatan, Mexico. The...

Amidst global challenges to food security and sustainability, this chapter explores the pivotal role of legumes.

Bemisia tabaci transmits begomoviruses that cause the most devastating disease of Capsicum chinense in tropical regions. Here we first evaluated the incidence and severity of Begomovirus symptoms on habanero pepper landraces H-224 and H-241 and commercial cultivar Jaguar that were naturally infested with B. tabaci in the field. Then we treated H-241 in the greenhouse...

The objective of this experiment was to assess the impact of different planting patterns on light availability for cowpea within the intercrop canopy, as well as to evaluate the corresponding effects on cowpea's physiological characteristics and grain yield in maize/cowpea intercropping systems.

Discharge of agro-industrial wastewater causes severe damage to the environment due to the various hazardous components it contains. Progressive circular agriculture and industry involve closed cycles and zero-waste principles; therefore, waste treatment for subsequent reuse is of great interest. The microbial fuel cell (MFC) is a promising sustainable technology capable of treating wastewater at low...

We assessed the emergence, growth, phenotypic plasticity and quality of both landrace and commercial tomato fruits under conditions of elevated temperature and increased CO2 concentrations [CO2]. Four growth chambers were used in which temperature and [CO2] differed: LTLC (30 °C, 400 µmol CO2 mol−1), LTHC (30 °C, 1200 µmol CO2 mol−1), HTLC (40 °C, 400...

In many parts of the world, chemical pesticides are the primary method of pest control in maize (Zea mays L.) crops. Concerns about the negative consequences of chemical pesticide use on people’s health and the environment, as well as the emergence of insecticide resistance, have accelerated attempts to discover alternatives that are effective, low-risk, and...

Intercropping is extensively used to increase land productivity and agricultural benefits. In developing countries, intercropping has historically been one of the most widely used cropping systems. Crop models have been used to assess risk productivity over time and space, particularly in monocropping systems. Crop models, such as the Decision Support System for Agrotechnology Transfer (DSSAT),...

In the last decade, attention has been drawn to a defense priming mechanism between plants of the same species through volatile organic compounds so that neighboring plants can prepare for the potential arrival of herbivorous insects. The induction of plant response priming by Tetranychus urticae Koch (Tetranychidae) in Phaseolus vulgaris (Fabaceae) seedlings was evaluated through...

This work was carried out to evaluate the insecticidal effect of mono, bi and trimetallic nanoparticles (NPs) from leaf extract of habanero pepper (Capsicum chinense Jacq.) on the red flour beetle (Tribolium castaneum herbst.) and cotton mealybug (Phenacoccus solenopsis Tinsley). The results showed that Cu NPs, Cu/Mn NPs and Zn/Cu NPs had high insecticidal effect...

Aunque el sistema de cultivo intercalado de la Península de Yucatán se considera amigable con el medio ambiente y juega un papel crucial en la producción de alimentos esenciales para la dieta mexicana, todavía se caracteriza por un bajo rendimiento debido a la competencia inter e intraespecífica (es decir, la disposición espacial de dos o...

In developing countries, intercropping is commonly used to boost land productivity and agricultural benefits. However, in the Yucatan region of Mexico, maize (Zea mays L.) yields remain low, despite consistent fertilizer and pesticide inputs in traditional intercropping systems. Furthermore, little is known about the photosynthetic mechanisms that occur when maize plants interact with legumes, and...

Commercial formulations of two entomopathogenic fungi (Metarhizium anisopliae Metschnikoff and Beauveria bassiana Balsamo) and two strains of Bacillus thuringiensis (B. thuringiensis var. kurstaki and B. thuringiensis var. aizawai) were evaluated against S. frugiperda and H. zea in two fields in the Yucatan Peninsula. In both locations, M. anisopliae and B. bassiana had similar efficacy (Davis...

Intercropping is the process of planting two or more crops simultaneously in the same field in order to provide greater ecosystem services (i.e. services related to sustainable land and water use, climate change mitigation, and ecosystem restoration). In southern Mexico, the cereal-legume intercropping is a traditional cropping practice that is declining overtime. This paper provides...

ContextMaize (Zea mays L.) is the most important cereal crop grown in Uganda, with more than 50% of agricultural households participating in its cultivation, contributing to food security and livelihoods. However, maize production faces multiple challenges, including climate variability, water scarcity, and poor soil fertility, particularly depletion of nitrogen (N), which limits yield potential across...

In recent decades, intercropping has emerged as a useful alternative to combat nitrogen (N) losses in the environment. Therefore, the objective of this work was to study the effect of the maize-legume intercrop on the potential losses of N from the soil. Three treatments were studied: maize+ crotalaria, maize+ cowpea and maize monoculture. The results...
