The experiment was completed to evaluate the responses of forage yield and silage quality of dual-purpose corn hybrids to urea fertigation. For this purpose, two studies were conducted each as a split plot experiment based on a randomized complete block design with three replications at two locations in research farms of College of Agriculture, Isfahan University of Technology, Isfahan, Iran, i...
Phosphorus (P) and iron (Fe) are essential nutrients for plants. Iron availability is low in calcareous soils of Iran due to the excessive amounts of CaCO3 and high pH. Overfertilization of P fertilizers may also decrease Fe availability. The objective of this study was to evaluate the effect of P and Fe on the growth and chemical composition of corn (Zea mays L.) under greenhouse conditions. T...
In order to investigate the effect of salicylic acid and humic acid to mitigate the impact of drought tension during pollination of forage maize, the present experiment was conducted as split plots based on randomized complete blocks design with three replications at Isfahan University of Technology. Drought tension levels included: without tension (control), mild tension (75 percent crop capa...
to study the effects of two irrigation regimes and application of barley residue, zeolite and superabsorbent polymer on forage yield and some physiological traits of maize and sorghum, an experiment was conducted over two years in kerman, iran. a randomized complete block design arranged in a factorial split was used with three replications. two irrigation regimes of normal irrigation and water...
to study the effect of planting rates and harvest time on forage quality of maize in maize-cowpea intercropping, an experiment was conducted at the research farm of zabol university, during 2007 and 2008. the experiment was arranged in a 7×2 factorial one in complete randomized block design with 4 replications. the two factors consisted of seven planting ratios of maize and cowpea (100:100, 100...
This study was conducted to quantitatively evaluate selfed (S1, S2 and S3) and open pollinated (OP1, OP2 and OP3) generations of alfalfa in terms of inbreeding depression and general combining ability of S2 families of alfalfa ecotypes. Selfing of selected plants to produce three generations of S1, S2 and S3 generations were performed under the field conditions and the clones of each selfed- ge...
abstract this study investigates the teachers’ correction of students’ spoken errors of linguistic forms in efl classes, aiming at (a) examining the relationship between the learners’ proficiency level and the provision of corrective feedback types, (b) exploring the extent to which teachers’ use of different corrective feedback types is related to the immediate types of context in which err...
in order to evaluate quantity and quality hairy vetch (vicia villosa l.) yield in the pure and mixed cropping with barley (hordeum vulgare l.) and triticale (triticosecale) the experiment was conducted at agricultural research station (khodabande) under dryland conditions during 2006 -2008. field experiments were arranged in a randomized complete blocks design with 9 treatments in four replicat...
Nitrogen fertilization is critical to optimize short-term crop yield, but its long-term effect on soil organic C (SOC) is uncertain. Here, we clarify the impact of N fertilization on SOC in typical maize-based (Zea mays L.) Midwest U.S. cropping systems by accounting for site-to-site variability in maize yield response to N fertilization. Within continuous maize and maize-soybean [Glycine max (...
To determine the appropriate proportion of oat mixed cropped with berseem clover under manure application levels, an experiment was carried out in the crop year 2015-2016; this study was carried out in Khuzestan Agricultural Sciences and Natural Resources University, as a split-plot design on the basis of RCBD with three replications. In this experiment, manure levels including: 0, 12, 24and 3...
