The irrigation system in Kobo-Girrana valley is extensively developed into modern drip irrigation using ground water sources. Tomato and onion are among the major vegetables grown under drip irrigation. However, the drip lateral spacing is fixed to 1m for all irrigated crops. This lead to low cro...

Agriculture, whether in the Corn Belt of the United States, the massive rice producing areas of Southeast Asia, or the bean harvest of a smallholder producer in Central America, is the basis for feeding the world. Agriculture systems are highly complex and heterogeneous in both space and time. Th...

Understanding soil hydraulic properties is crucial for planning effective soil and water management practices. A study was conducted to evaluate the effects of different biochar and charcoal treatments on soil-hydraulic properties of agricultural soils. Biochar and charcoal treatments were applie...

Restrictive soil layers commonly known as hardpans restrict water and airflow in the soil profile and impede plant root growth below the plough depth. Preventing hardpans to form or ameliorate existing hardpans will allow plants root more deeply, increase water infiltration and reduce runoff, all...

This paper does not present an exhaustive review of the properties of acid soils. Rather, emphasis is placed on three topics, viz. soil pH, exchange properties, and sulfate sorption, with bias towards the author’s experience with soils from the world humid tropical region. The discussion on pH an...

Plant growth-promoting microbes function as bacterial inoculants and contribute to the enhancement of agronomic efficacy by lowering production costs and environmental pollution. Interactions between plants and microbes are either antagonistic or synergistic within soil. The efficiency of plant g...

Biocontrol using Fusarium oxysporum: a critical component of integrated striga management
Cassava is drought-tolerant and grows reasonably well in relatively infertile soils where other crops would fail. However, production could be further increased if important soil-related constraints are addressed. In order to supply cassava plants with the nutrients required for optimal productio...
