Foliar spraying of a small amount of micronutrients (iron and zinc) may increase the yield of anise(Pimpinella anisum L.), an anethole-rich important medicinal plant. In order to evaluate the effect of iron (Fe) and zinc (Zn) spraying (0, 2, 4, and 6 g l-1) on the nutrient contents and the essential oils of anise, a factorial experiment was conducted based on a randomized complete block design ...

In order to study effect of phosphorus fertilizer and micronutrients foliar application on yield sorghum, a field experiment was conducted in at 2011 in Research Farm of Payame Noor University of Zahedan, Iran. This experiment was done as split plot Based on randomized complete block design with three replications. Experiment treatments included: micronutrients foliar application containing ele...

Saffron production will be increased in arid regions by providing sufficient water through appropriate agronomic strategies. Therefore, in this investigation the impact of different rates of super absorbent polymer (SAP) including 0,10, 20, 30, 40 and 50 kg ha-1 was studied on saffron flowering traits during two growth cycles. Results showed that the influence of experimental factor was signifi...

Switchgrass (Panicum virgatum L.) is being evaluated as a bioenergy crop for the northern Great Plains. Field measurements of CO2, CH4, and N2O flux are needed to estimate the net greenhouse gas (GHG) balance of this biofeedstock. The study objective was to determine effects of recommended Nitrogen (N) fertilization (67 kg ha 1 of N applied) and unfertilized switchgrass on growing season soil-a...
