The intercropping is a production system that aims to provide increased yield with less environmental impact, due to greater efficiency in the use of natural resources and inputs involved in the production process. An experiment was carried out to evaluate the agronomic viability of kale and New Zealand spinach intercropping as a function of the spinach transplanting time. (0, 14, 28, 42, 56, 7...

effect of foliar spraying by humic acid on mineral leaf composition, yield and fruit quality of apple (malus domestica l. cv. ‘granny smith’) was studied. an experiment based on randomized complete design was conducted in khorramdare city of zanjan province. spraying of humic acid was conducted in four levels 0, 5, 10 and 15 mg/l on eight year-old ‘granny smith’ apples grafted on mm106 rootstoc...

in order to study the effects of foliar application of si (5/1000 ratio), k (2/1000 ratio) and zn (2/1000 ratio) on rice (cv. tarom hashem), an on-farm experiment carried out based on randomized complete block design with three replications in 2012. some traits such as paddy yield and yield components, neck blast disease and stem borer damage were evaluated. results showed that the effect of fo...

in order to study the effect of  foliar application of zinc and iron on germination of soybaen seed under different level of irrigation, an experiment was conducted in 2009 at shahrekord agricultural research center. main factor was including of four levels of drought stress as irrigation (irrigation after 60, 80, 100 and 120 mm evaporation from class a evaporation basin) and sub factor was inc...

Anthocyanins, soluble sugars, and organic acids play a vital role in the color flavor of grape berries. N KH2PO4 are essential nutrients for growth development. However, research on effects foliar spraying skin grapes under different levels were not systematic. In this study, “Flame seedless” used as test material. There six treatments experiment, including low nitrogen (LN), + (LNK), moderate ...

Foliar application or minerals is a methodology to promote growth and/or yield and protect plants against different kinds of stresses. Currently there great interest in evaluating the effect nanoparticles for enhancing these treatments. This study was performed evaluate compare foliar zinc oxide (ZnO) (ZnO-NPs) on safflower under irrigation regimes. applications ZnO all concentrations (4, 6, 8,...

The traditional indoor spraying technique to control Anopheles albimanus mosquitos was compared with a selective method that targets their preferred resting sites in coastal villages of southern Mexico. We also determined whether mosquitos changed their preferred resting sites following insecticide applications. In the selective spraying approach, two 1-m wide horizontal swaths of bendiocarb in...

abstract the present research was conducted in a commercial orchard of pistachio during 2006-2007 in rafsanjan, iran. gibberellic acid (ga3) were applied at 0, 25, 50 and 75 mgl-1 and at three time of spray (the first of june, july and august) on “ahmad-aghai” pistachio cultivar. two branches of each tree was sprayed during two years of study. spraying at june had least of early splitting. ga3 ...

Salinity stress limits crop growth and productivity, including legumes in various regions worldwide. The impact of foliar-applied zinc nanoparticles (ZnNPs) combined nano-loaded with moringa extracts (ZnONPs) on salt tolerance faba beans (cultivar, Giza-716) grown under saline soil (50 100 mM NaCl) was investigated. Moringa oleifera extract has been used as a chelating agent to synthesize oxide...
