in order to study the yield and forage quality of intercropping barley (hordeum vulgare) and mustard (sinapis alba) in different planting dates, a factorial experiment based on randomized completely block design with three replications was carried out at farm research station, gonbad -e- qabus university. factors were included as three planting dates (15 november, 6 and 20 december 2006) and fo...

Pinus taeda L. plantations in the United States are typically established using rows that are spaced 3 to 4 m apart. Although one company now plants pines in 6.1 m rows, reports on performance using this row spacing are rare. This paper provides a case study (established at the Solon Dixon Forestry Education Center) that compares two densities [672 vs 1344 seedlings per ha (SPH)] when fixing th...

Higher prices for hardwood stumpage and changes in agricultural policies may favor afforestation on sites in the Lower Mississippi Alluvial Valley (LMAV) which are suitable for Eastern cottonwood (Popu/us de/toides Bartr.). We examined the potential returns to a landowner growing cottonwood on three soil classes common to the LMAV. We specified the conditions under which we think such afforesta...

Long-term, multi-decade research on planted tree survival in urban settings is sparse. One understudied environment highway rights-of-way (ROW), lands adjacent to high-speed, unsignalized roadways. We conducted a re-inventory of planting cohorts northern Illinois, U.S. 48 km-long near Chicago which were 10-, 21-, and 30-years old evaluate long-term patterns diversity. Using each randomly select...

in order to evaluate the effect of row space and weed management on weed population, chickpea yield and yield components, a factorial experiment based on rcbd with three replications was conducted at field research of agriculture college of lorestan university in cropping season of 2006-2007. in this research experimental factors were chickpea row spaces with four levels (15, 20, 30 and 40 cm w...

Abstract—Gladiolus is an important cash crop and is grown mainly for its elegant spikes. Traditionally the gladiolus corms are planted manually which is very tedious, time consuming and labor intensive operation. So far, there is no planter available for planting of gladiolus corms. With a view to mechanize the planting operation of this horticultural crop, a prototype of 4-row gladiolus plante...

We assessed the potential profitability of twin-row (TR) planting geometry as a water productivity-enhancing practice and skip-row irrigation (SRI) water-conserving in furrow-irrigated cotton (Gossypium hirsutum L.) soybean (Glycine max L.). Data from agronomic experiments carried on Dundee silt loam soils indicate that, average, TR increases by US$344 ha?1 for all-row irrigated (ARI), $401 SRI...

In a field experiment, spreader plants of variety N13 infected with ratoon stunting disease were interplanted with healthy plants of indicator variety NC0376. When cane knives were not disinfected during manual harvesting, 62% ofstalks ofNC0376 down-row from the spreader plants were found to be infected after one harvest, and almost all the stalks were infected after three harvests. This compar...

Objective: For investigation of intercropping of maize and faba bean, an experiment was conducted in Research Station of Agriculture Faculty of Tabriz University during growing season of 2013. Methods: Experimental design was randomized complete block design with three replications and seven treatment. Treatments included one row intercropping (1:1), 4 strip intercropping pattern with ratios of...
