to study the effects of urea foliar spray at different plant growth stages on grain yield and protein percentage of two dryland wheat varieties of sardari and azar 2, an experiment was conducted in east mangor agricultural station of mahabad in 2007– 2008. the experiment design was split plot based on randomized complete block design with three replications. treatments were 50 gr×10 m-2 n as ur...

The present study was carried out at the experimental farm of Tag El-Ezz Agricultural Research Station (30o 59\ N latitude, 31o 58\ E longitude´), Center, Dakahlia Governorate, Egypt, to effect foliar spraying arginine on four soybean cultivars under salinity stress. This experiment laid in a split plot design with three replicates during two successive summer seasons 2020 and 2021.

a split plot experiment based on randomized complete block design (rcbd) with three replications was conducted in 2012,treatments were included the time of foliar application with 3 levels (tillering stage, heading stage and no spray (control)) as main factor and cultivars in 4 levels (sardari, rijav, biseton and rashid) as the second factor. plant characteristics such as plant height, length o...

This study investigated the effects of the sawdust vermicompost extract (aqueous extract) on yield and chemical quality of Dracaena marginata var.‘Tricolor’ grown under four sawdust vermicompost extract solutions (0, 250, 500 and 1000 ppm). The sawdust vermicompost extract was prepared using non-aerated extraction methods with 1:10 (v/v) of sawdust vermicompost to water and was sprayed three ti...

The apoplastic pH of intact Forsythiaxintermedia (cv. Lynwood) and tomato (Solanum lycopersicum) plants has been manipulated using buffered foliar sprays, and thereby stomatal conductance (g(s)), leaf growth rate, and plant water loss have been controlled. The more alkaline the pH of the foliar spray, the lower the g(s) and/or leaf growth rate subsequently measured. The most alkaline pH that wa...

The results of foliar fertilization spring wheat crops Struna myronivska variety with aqueous solutions zinc, manganese and their chelated analogues in EDTA (zinc complexates) at different stages plant growth development are presented. research was conducted on sodmedium podzolic gley sandy soils Polissia contaminated by radionuclides after the Chernobyl accident. On average, 2014–2016 yy. plan...

Foliar Micro-nutrition is the application of micronutrients to plants by spraying directly onto their leaves. Although it not economical spray macronutrients and through foliar spraying, researchers prefer soil for applications micronutrients. Several researches have demonstrated that method which used deliver required micronutrient in appropriate concentration improve nutrient status along wit...
