Intercropping of silage maize (Zea mays L.) and alfalfa (Medicago sativa is not a common practice because generally reduces grain biomass yield. The objective this research was to evaluate the productivity profitability maize–alfalfa intercropping, with goal establish increase in first year production. experiment conducted Fargo Prosper, ND, USA, 2014–2017. design randomized complete block four...

The evaluation of the nutritional value and parameters ruminal fermentation tropical forages is important, aiming at its efficient use in ruminant feeding. This study was developed to evaluate forage accumulation, chemical composition, protodioscin content, digestibility, vitro degradation kinetics different Brachiaria spp. cultivars periods. research carried out semi-arid region Brazil, from A...

There are several examples of heuristic rules first proposed from empirical observation, which eventually earned physicochemical validity after the fundamental derivation of a posteriori. This may be the case of Sherwood’s plot – for which a sound rationalization from first principles, entailing enthalpy and mass balances, is provided here; it applies to (fine) chemicals undergoing concentr...

a study was conducted at the research station of department of horticultural science (tehran university, karaj) to evaluate the effects of water stress on yield, growth and some physiological parameters in iranian melon. the experiment was set out in a split plot design with three replicates. treatments consisted of factorial arrangement of three irrigation levels (starting irrigation at -50, -...

A long fallow period (?15 mo) in a winter wheat (Triticum aestivum L.)–fallow rotation (W-F) cropping system is meant to store soil water for the following crop but loss of quality, low precipitation use-efficiency, and increased cost management are among its drawbacks. Replacing portion with short-season cover may alleviate these The objectives this study were evaluate available at planting (A...

The aim of the study was to evaluate content and uptake macronutrients (P, Ca, Mg, K) in Solanum tuberosum tubers effect care with biostimulants from a three-year field experiment conducted at Agricultural Experimental Station Zawady, Poland. set up split-plot arrangement three replications. first factor two varieties edible potato (Oberon Malaga), second five treatments herbicide biostimulants...

in order to evaluate the effect of different nitrogen application methods on yield and yield components of winter wheat, a field experiment with split plot arrangement in randomized completely blocks design with four replicates was conducted during 2006-07. basal dressing in three levels (with no basal dressing, strip and distributing nitrogen fertilizer) as main plot and top dressing in six le...

in order to study the effect of supplementary irrigation and different plant densities on grain yield and yield components of chickpea cv hashem, an experiment was conducted as split plot arrangement in a randomized complete block design with three replications in sirvan, ilam during 2008-2009 cropping season. main plot included supplementary irrigation (check as non-irrigation, supplementary i...

in order to study fruit  quality changes in apple cultivar gala, related to ripening stage and storage time, an experiment was conducted in a split plot arrangement in randomized complete block design with four replicationsin the area of damavand– jaban for three years. five levels of sampling times in storage were assigned to main plots, and three levels of harvesting times were randomized in ...

wheat residues management and modification in tillage time are among suggested practices in weed control. to evaluate the effects of wheat residues and tillage time on weed dry matter and leaf area, corn dry matter and corn grain yield, a study was conducted at darab agriculture and natural resource college, shiraz university during growing season of 2008-2009. this experiment was conducted in ...
