Foliar application of nitrogen (N) is used to supplement soil N application in order to meet high N requirements of crops (Oosterhuis, 1999). Urea is the most common foliar N source in cotton, due to its relatively low toxicity, quick absorption, and low cost (Maples and Baker, 1993; McConnell et al., 1998, Oosterhuis and Bondada, 2001). However in the literature, reports of yield increments wi...

Plants adopt ecological strategy to resist environmental changes and increase their resource-use efficiency. The ecological strategy includes changes in physiological traits and leaf morphology, which may result in simultaneous variations in foliar N concentration and the ratio of intercellular CO2 concentration to ambient CO2 concentration (ci/ca). This in turn links to foliar carbon isotope d...

This research was aimed to study the interest of flower analysis as a tool for the prognosis of nutritional deficiencies on cherry trees and confirm the influence of rootstock on the mineral uptake by tree. This type of diagnosis is compared with foliar analysis. The trial was established on a calcareous clay-loam soil, where ‘Sunburst’ cultivar on eight rootstocks: CAB 6P, CAB 11E, Masto de Mo...

The study was undertaken to evaluate the effect of foliar sulphur (S) nutrition through Ammonium Thiosulphate (ATS) under conservation management on growth, photosynthetic efficiency and productivity rainfed pearl millet in dryland ecologies New Delhi 2021 2022 crop years. established (ZTCRret) achieved significantly higher growth rate (CGR) relative (RGR) as a result improved photosynthesis te...

The technology of producing fruits containing an increased amount elements essential for the health human body, including silicon, has become very important in recent years. Due to popularity apple tree cultivation Europe, appropriate research been undertaken. aim experiment was determine advisability foliar silicon nutrition cultivation. Apple cultivars ‘Gala Schniga’, ‘Ligol’ and ‘Topaz’ were...

Surface mining in Appalachia disrupts large areas of forested land. Federal and state laws require disturbed lands be reclaimed by re-constructing the landscape and replacing soil materials to provide a rooting medium. If insufficient quantities of native topsoil are available, substitute materials derived from the overburden may be used as soil media. This study examined soil and foliar nutrie...

Advanced site-specific determination of grain protein content by remote sensing can provide opportunities to optimize the strategies for purchasing and pricing grain, and to maximize the grain output by adjusting field inputs. Field experiments were performed to study the relationship between grain quality indicators and foliar nitrogen concentration. Foliar nitrogen concentration at the anthes...

The objective of this study is to identify an adequate zinc (Zn) foliar spray concentration which corrects Zn deficiency without disrupting other plant mineral contents, enhances plant growth, and thereby corn silage yield when grown on sandy soil. A field experiment was conducted using five Zn foliar spray concentrations (w/v): 0.03%, 0.07%, 0.10%, 0.14% and 0.18%. Zn sulfate (ZnSO4. 7H2O) was...

There seems to be conflicting information about foliar fertilizers and their timing of application to cotton. Much of the confusion lies in the variety of fertilizer products available. A cotton fanner now has a choice of applying foliar fertilizers (according to fertilizer labels) beginning at the first true leaf stage and continuing until defoliation. This newsletter will focus on available i...
