The purpose of this study was to see the effect giving Vesicle Arbuscular Mycorrhizae (VAM) on vegetative growth white corn (Zea mays L), distance treatment plant and interaction both them corn. This used a randomized block design (RBD) factorial with two-factor three replications. first factor is VAM (A) various doses consisting A1 (10 g/plot), A2 (20 g/plot) A3 (30 while second spacing (J) si...
introduction in dry areas, water is the limiting factor in improving agricultural production. saving the annual precipitation in the soil is very effective in dryland farming. the amount of rainfall that infiltrates the soil depends on the amount of soil permeability and runoff. the surface remains will be able to better permeable prevent runoff and raindrops and reduce erosion. in addition, ev...
Tef is a small-seeded staple crop endemic to Ethiopia. However, its yield low, constrained partly due improper agronomic practices and lodging. Thus, during the 2019–2020 cropping season, field experiment was carried out at Reef Tokko Taanne Hamilee in Hababo Guduru district, Western Ethiopia examine effects of seed rate inter-row spacing on growth, phenology, yield, lodging severity tef crop. ...
we describe here a suitable approach for the synthesis of n-unsubstituted monocyclic b-lactams under mild reaction conditions by the annelation of imines with substituted acetylchlorides. in this method the reaily available phtalimidoacetyl chloride were allowed to react with - dibenzylideneiminotoluene (hydrobenzamide) in the presence of an equimolar amount of triethylamine in refluxing toluen...
Low density plantings complemented by natural regeneration is an increasingly common reforestation technique to ensure growth of a sufficient number of trees from desired species while maintaining natural processes such as succession. One such form of low density planting that aims at lowering establishment costs—oak clusters—has been developed as an alternative to row planting since the 1980s ...
With the continuous improvement of mechanization level and development new crop varieties, optimal strip width for intercropping crops is important. In this study, field experiments were conducted to analyze effects different row spacings planting patterns on photosynthesis, chlorophyll fluorescence, related enzyme activities maize ear leaves in a maize–soybean system using two (wide–narrow row...
saluk mount is selected for devonian biostratigraphy. this area located at southwest of bojnurd. in this study three sections are selected and two sections, chahar-borj and tabar sections with a thickness of 650 m, which consist mainly of calcareous sediments was studied in detailed but third section, qelli section, with a thickness of about 450m which consist mainly of sandstone and evaporates...
A field inoculation method was developed to produce Meloidogyne spp. infestation sites with minimal quantities of nematode inoculum and with a reduced labor requirement compared to previous techniques. In a preseason-methyl bromidefumigated site, nematode egg suspensions were delivered at concentrations of 0 or 10(x) eggs/m of row where x = 2.12, 2.82, 3.52, or 4.22 through a drip line attached...
a field study was conducted to determine the effects of planting method, density and nicosulforon on corn (ksc704) and weeds grown in corn at agricultural and natural resources research center of khorasan-razavi province, iran in 2009-2010 growing season. the treatments were: three planting methods (one row, two row and in-row), two planting density (75000 and 90000 plants/ha) and three doses o...
this is an original study on the effect of a polyisobutylene – polydimethylsiloxane (pibpdms) block copolymer modifier used as an interfacial active agent on the dynamics behaviour of single newtonian drops suspended in a polyisobutylene (pib) newtonian matrix. the results were divided in two sections. the first part included the experiments carried out on the non-modified and 2% block cop...
