To assessment growth physiological charachteristics of two hybrids of sweet corn affected different irrigation pattern and zinc fertilization, a research was conducted as split plot factorial experiment based on randomized complete blocks design with three replications. Main factor included different levels of irrigation pattern included conventional furrow irrigation, fixed every other furrow ...

A main objective of restoration and afforestation at post-mining sites is establishing a long-term sustainable ecosystem which depends on adaptations of tree species and which in turn depends on the soil nutrient flux. The nutrient concentration (nitrogen (N), P, K, Ca, Mg, and sulfur (S)) of Scots pine needles was investigated in reclaimed mine soils (RMS) located at the following post-mining ...

An improvement in growth, condition, raw material quality, and resistance of vegetable plants to adverse stress conditions or agricultural pests can be achieved by using foliar-applied biostimulators. Cover cropping is also of great importance since it contributes, among others, to a better use of environmental conditions and fertilization by plants. In the period 2009–2011, a field experiment ...

Abstract The experiments was carried out in an unheated Plastic house unit of the Department Horticulture and Landscape Design / College Agriculture Forestry University Mosul for years 2021-2022 with aim enhancement vegetative growth three cultivars Strawberry, Festival, Ruby Gem Liberation D, Orleans. Factorial experiment according to split-plot system so that were placed main-plot, while nano...

to determine the correlation between grain yield and its components in some grain corn hybrids and their cause and effect relationships in various fertilizer application methods, an experiment was carried out as split plot based on randomized complete block design with two fertilizer application methods (urea foliar application and soil application method), four grain corn hybrids (ns 640, kons...

This study evaluated the combined effect of foliar spray inoculation with plant growth-promoting bacteria (PGPB) and nitrogen doses on yield, development, nutritive value Megathyrsus maximus cv. BRS Zuri. The experimental design was randomized blocks four replications, repeated measures in time. Foliar two (Azospirillum brasilense Ab-V5 (CNPSo 2083) Ab-V6 2084) Pseudomonas fluorescens 2799)) 40...

a field experiment was conducted to study the physical properties of maize grain in response to different urea fertilization methods (urea foliar spraying and soil application), three harvest times (grain moisture content of 20, 30 and 40 pecent) in four maize hybrids (three foreign hybrids e.g. ns640, jeta600 , konsur580 and one common hybrid, sc704 as control) at khorram abad agricultural res...

The 6-year effects of urea (46--) and ammonium nitrate (AN; 34--) fertilizers, applied alone and in combination with other nutrients, on tree growth and foliar nutrition were evaluated in a -year-old, thinned lodgepole pine (Pinus contorta Dougl. var. latifolia Engelm.) stand in central British Columbia. Results indicate that lodgepole pine has no clear preference for a particular nitroge...

Most studies on the effects of elevated CO2 have focused on the effects on plant growth and ecosystem processes. Fewer studies have examined the effects of elevated CO2 on herbivory, and of these, most have examined feeding rates in laboratory conditions. Our study takes advantage of an open-top CO2 fertilization study in a Florida scrub-oak community to examine the effects of elevated CO2 on h...
