abstract supplementary irrigation for suitable crops production in most area of iran is necessary. in order to study supplementary irrigation effects on yield and yield components of three lentil (lens culinaris medik.) cultivars, an experiment was carried out as split block based on randomized complete block design with three replications at research field, college of agriculture, ferdowsi uni...

the present study evaluated the effects of different dosages herbicides oxyfluorfen and trifluralin on crop properties of garlic, including plant height, number of cloves per bulbs as well as economical and biological yield of garlic. in this research, a randomized complete block design, with seven treatments and three replications, along with a control sample (weeding and no weed control), was...

In complex task domains, such as games, students may exceed their teachers. Such tasks afford diverse means to tradeoff one type of performance for another, combining task elements in novel ways to yield method variations and strategy discoveries that, if mastered, might produce large or small leaps in performance. For the researcher interested in the development of extreme expertise in the wil...

in order to determine the appropriate plant density of spotted bean in yasouj, a field experiment was conducted in 2008 as a factorial in a randomized complete block design with three replications. three spotted bean cultivars (keshavarzi, talash and oshtori) were sown at five plant densities (10, 20, 30, 40 and 50 plant.m-2). results showed that effect of plant density, cultivar and interactio...

according to urgent need of corn to nitrogen and since this element play a main role in improving of yield corn, thus, in order to investigate the effect of different levels of urea on yield and yield components of corn 704, an experiment was conducted randomized block with three replications in cropping year of 2012. experimental treatments included six levels of urea (0, 30, 60, 90, 120 and 1...

Eight faba bean (Vicia faba L.) genotypes were grown at lowlands of the west-Mediterranean region of Turkey in order to estimate the broad-sense heritability for plant height, number of stems and pods per plant, seed yield, biological yield, 100-seed weight, days to flowering and maturity. The heritability for plant height, number of stems and pods per plant, seed yield, biological yield, 100-s...

Louisianin A (1) was treated with phosphoryl chloride (POC13) at 120~ 125°C3) to obtain chloro derivative (2) in 86% yield. 2 was reduced by Zn-AcOH at 50°C4) to afford 3 (52% yield) and 4 (35% yield). Furthermore, under the same condition, 3 was dechlorinated to give 4 in 48% yield. Moreover, 4 was oxidized in the treatment of CrO3-pyridine5) to obtain louisianin C (5) in 75% yield. Finally, 5...

To survey the effects of chemical and biological phosphorus on the yield and essential oil of Satureja hortensis L. as an important medicinal plant, factorial experiment was conducted based on randomized complete block design with three replicates at Research Station of Faculty of Agriculture, Urmia University in 2011. The treatments were chemical phosphorus fertilizer with four levels (0, 50, ...
