We evaluated factors influencing the development of autumn red coloration in leaves of sugar maple (Acer saccharum Marsh.) by measuring mineral nutrient and carbohydrate concentrations, water content, and phenology of color development of leaves from 16 mature open-grown trees on 12 dates from June through October 1999. Mean foliar nutrient and carbohydrate concentrations and water content were...

In order to study effect of phosphorus fertilizer and micronutrients foliar application on yield sorghum, a field experiment was conducted in at 2011 in Research Farm of Payame Noor University of Zahedan, Iran. This experiment was done as split plot Based on randomized complete block design with three replications. Experiment treatments included: micronutrients foliar application containing ele...

BACKGROUND Dispersal events between habitat patches in a landscape mosaic can structure ecological communities and influence the functioning of agrosystems. Here we investigated whether short-distance dispersal events between vineyard and forest patches shape foliar fungal communities. We hypothesized that these communities homogenize between habitats over the course of the growing season, part...

The effect of exogenous application; seed priming or foliar spraying of salicylic acid (SA) on Yecora Rojo and Paragon wheat cv. under NaCl-salinity. Gas exchange parameters, growth parameters, yield and yield components were reduced in both cultivars under salinity stress with foliar spray and soaking seeds. Exogenous application of SA through foliar spraying or seed soaking showed a slight in...

Foliar fertilization is a widely used method used to supplement soil applications to improve the yield and quality of field crops. However, questions and uncertainty surround this practice. Numerous field trials have clearly demonstrated the uptake of foliar-applied nutrients by leaves and subsequent translocation to the fruit. In cotton, foliar-applied N was rapidly absorbed by the leaf (30% w...

How plants develop adaptive strategies to efficiently use nutrients on infertile soils is an important topic in plant ecology. It has been suggested that, with decreasing phosphorus (P) availability, plants increase photosynthetic P-use efficiency (PPUE) (i.e., the ratio of instantaneous photosynthetic carbon assimilation rate per unit foliar P). However, the mechanism to increase PPUE remains ...

The effects of Pratylenchus vulnus on growth and nutrition of Cadaman peach and Ishtara and Julior plum rootstocks were evaluated in a microplot experiment lasting two growing seasons. Cadaman peach was the only rootstock that showed suppressed growth for all growth parameters at the end of the first year. At the end of the second growing season, dry and fresh shoot weights as well as shoot len...

Cultural practices (CPs) can be harnessed for the management of foliar and soilborne diseases by creating an environment which is favorable for the crop and unfavorable for the pathogen. Certain CPs, e.g. flooding and sanitation, are used mainly for pest control while others, e.g. irrigation, can be used for both crop management and pest control. Some CPs, e.g. deep plowing, crop rotation, flam...

This experiment was aimed to study the effect of interaction herbicides and varieties with different types foliar nutrition in production highest yield for three wheat varieties.
