Fluctuation in rainfall in Ogun-Osun River Basin, Nigeria in the recent times is a challenge to crop production. Therefore, agronomic practices need to be designed to improve water productivity under rainfed conditions. Improving water productivity requires vapour shift or transfer whereby soil physical conditions, soil fertility, crop varieties and agronomy are applied in tandem and managed to shift the evaporation into useful transpiration by plants. Water conservation practices: Tied ridge, Mulch, Soil bund, Tied ridge plus Soil bund, Tied ridge plus Mulch, Mulch plus Soil bund and Direct sowing were used in cultivating Soybeans for two rainy seasons in Ile-Ife, Nigeria. Full and deficit irrigation application during reproductive stages were used with in-line drip irrigation for two seasons.
Seasonal rainfall influenced the water storage in the soil. Transpiration, seed yield and water productivity were related to Total Intercepted Photosynthetically Active Radiation. Yield and economic productivity increased under water conservation practices. Productivity decreased most when irrigation was skipped during seed filling and the production costs under drip system are high. Rainfed cultivation of soybeans when rainfall and solar radiation are optimum, is the best option.
The AquaCrop model was calibrated and validated to predict canopy cover, aerial dry biomass, seed yield, soil water content, crop water use, and water productivity under full and deficit irrigation conditions. The model performed the best in simulating aerial dry biomass under full irrigation. The simulated and measured data compare adequately and the performance of the model was satisfactory.

Closed circuit trickle irrigation is a form of micro irrigation that increases energy and water efficiency by using closed circuit drip irrigation systems designs. Modifications are made to traditional micro irrigation methods to reduce some of the problems and constraints, such as low compressor water at the end of irrigation lines. This approach has proved successful for the irrigation of fruit trees and some vegetable and field crops. Closed circuits of drip irrigation systems require about half of the water needed by sprinkler or surface irrigation. Lower operating pressures and flow rates result in reduced energy costs, and a higher degree of water control is attainable as well. Plants can be supplied with more precise amounts of water, and disease and insect damage is reduced because plant foliage stays dry. Fertilizers can also be applied through this type of system, which can result in a reduction of fertilizer and fertilizer costs.
This new volume in the Research Advances in Sustainable Micro Irrigation book series presents a diverse collection of research on closed circuit irrigational technology and design and provides studies of its use on such crops as wheat, maize, yellow corn, soybeans, rice, and snap peas.
The book explores:
- Soil moisture and salinity distributions under modified sprinkler irrigation
- Performance of sprinkler irrigation
- Design considerations for closed circuit drip irrigation systems
- Performance of bubbler irrigation
- Energy and water savings of drip irrigation systems
- Automation of mini-sprinkler and drip irrigation systems
- Water and fertilizer use efficiencies for drip irrigated maize
- Evaluation of emitter clogging for drip irrigated systems
This book will be valuable for those interested in irrigation planning and management, namely, researchers, scientists, educators, upper-level students, agricultural extension services, and others.
