      Endogenous Technology Adoption Under Production Risk: Theory and Application to Irrigation Technology The objective of this paper is to present a theoretical framework that conceptualizes technology adoption as a decision process involving information acquisition by farmers who face yield uncertainty and vary in their risk preferences. vi international symposium on irrigation of horticultural crops. crop load and irrigation management during the latter stages of ripening: effects on vine water status, fruit dehydration and fruit composition of 'merlot' grapevines plant and soil water status behavior under different irrigation strategies in cultivar 'arbequina' olive. Abstract: Maximization of chemical utilization within the root zone of crops and minimization of groundwater contamination are the major objectives of chemigation under any irrigation system.

In this review, we found that RDI is largely implemented through three approaches: (1) growth stage-based deficit irrigation, (2) partial root-zone irrigation, and (3) subsurface dripper by: Root Zone Drying Irrigation practice simply involved interchanging the wet and dry sides in subsequent irrigations.

The application of potassium has significant role in increasing root penetration which can lessen the chances of damage under persistent drought that is why the healthy plant growth is observed under water stress.

For improved grain yield of maize, crop potassium acts as a potential osmolytes which is capable of producing tolerance against.

ABSTRACT. Field trials utilizing 15 N-depleted ammonium sulfate fertilizer were established at two locations, one on Yolo fine sandy loam at U.C. Davis, and the other on Hanford sandy loam at the Kearney Field Station, with corn as the test crop.

At Davis 3 irrigation regimes and 4 fertilizer rates were used, while at Kearney 6 fertilizer rates were used with uniform irrigation. Secondly, irrigation frequency can be relatively high under drip irrigation, which has been proven to be conducive to increasing both crop yield and water use efficiency (Kang and Zhang, ;Kang.

During and following irrigation events, as wetting fronts develop near the emitters, the root zone of the crop remains nearly saturated during and for some time after irrigation events, reducing Cited by: Applications of crop models include studying management at field sites, fertilizer and irrigation management, site specific farming, study of crop management options under climate variability.

AARI ameliorated the water deficit stress by enhancing the antioxidants contents to protect it against oxidative damage which modulated yield related components under irrigation water-regimes at T+B and T+H over control (CRI+T Cited by: 8.

Deficit irrigation (DI) is a watering strategy that can be applied by different types of irrigation application methods. The correct application of DI requires thorough understanding of the yield response to water (crop sensitivity to drought stress) and of the economic impact of reductions in harvest.

In regions where water resources are restrictive it can be more profitable for a farmer to.

Crop Science, 42, MacAdam, J.W, Nelson, C.J, (). Abstract. Plant growth and development are adversely affected by salinity – a major environmental stress that limits agricultural production. This chapter provides an overview of the physiological mechanisms by which growth and development of crop plants are affected by by: Publisher Summary.

This chapter highlights the application of physiological principles to elucidate and overcome environmental constraints to yield of individual crops and to illustrate how a commercial company utilizes principles of crop physiology and modeling to whole-farm risk management with a focus on productivity and environmental outcomes.

ORDI maximized the yield of the crop for different volumes of available irrigation water. The irrigation water productivity differed according to the cultivar, increasing for lower volumes of irrigation water (from kg m−3 to kg m−3 for Monalisa and Mirari cultivars, irrigated with % and 40% of the requirements, respectively).Cited by: 4.

Accordingly, while a number of genetic studies of root systems have shown positive associations between yield and certain root features (see below), some programs to improve yield under water deficit have resulted in a reduced root biomass (Bolaños and Edmeades, ; Bruce et al., ) or a decreased water conductivity of the roots (Richards Cited by: Downloadable (with restrictions).

Uncertainties in the estimation of evapotranspiration (ET1) using the crop coefficient (Kc)-reference ET method arise for deeply rooted crops and severe water stress. We expanded upon the crop coefficient–based model by modifying plant available water via a nonuniform root distribution that limited deep water extraction using daily estimated soil profile Author: Robert C.

Background Maize-soybean relay-intercropping (MSR) is a famous system of crop production in developing countries. However, maize shading under this system directly affects the light quality and intensity of soybean canopy.

The stems ('culms') grow to 40– cm tall; the leaves are linear, 15–40 cm long and 3–10 mm broad at the base of the plant, with leaves higher on the stems 2– mm broad.

Additionally, to accommodate the change in irrigation practices from surface to low volume systems, this research will re-evaluate the dynamics of root growth, root activity, nutrient and salt movement, and crop response to saline conditions under micro-irrigation.

In regions with Mediterranean climate, water is the major environmental resource that limits growth and production of plants, experiencing a long period of water scarcity during summer. Despite the fact that most plants developed morphological, anatomical, physiological, and biochemical mechanisms that allow to cope with such environments, these harsh summer conditions reduce growth, yield Cited by: 3.
