¬¬¬one of the most important limitations for selection of second crop in paddy fields in guilan is waterlogging in the second half of the year. for an evaluation of waterlogging effect (in adequate drainage) on canola yield, a lysimeter study was conducted implementing -10,-5,0 and +5 cm water level for 2,5,7 and 10 day durations at 3 plant growing stages namely: emergence, beginning of floweri...

Almond is one of the most important nut crops in Iran. Due to the suitable climatic conditions, Iran is one of the most important growing centers for wild and domesticated species of almond in world. Native genotypes typically are early flowering, due to late spring frost, often; they have been damaged. So frost damage to the flowers and early developing fruits is one of the most limiting facto...

Background: Hyssop (Hyssopus officinalis L.) is herbaceous perennial plants of Lamiaceae family grown in Europe, the Middle East, Asia, and Northern Africa. Objective: In this research, the effect of harvesting time was studied on essential oil, photosynthetic pigment, and some morphological characteristics of hyssop. Methods: A Field experiment was carried out during 2015/2016 at the Res...

introduction salinity is a major abiotic stress that affects approximately 7% of the world’s total land area. cotton (gossypium barbadense l.) is considered as one of the most important cash crops which is widely used for agricultural and industrial purposes. although, cotton is classified as one of the most salt-tolerant major crops but its growth and development are adversely affected by soil...

in order to evaluate the effects of drought stress at different phenological stages on growth indices of chickpea (cicer arietinum l.) cultivar jam, an experiment was carried out at the research greenhouse of faculty of agriculture, ferdowsi university of mashhad, using a completely randomized design with four replications. drought stress was applied by preventing irrigation until the soil mois...

to assessment alfalfa cultivars research project this research has been fulfilled in 2011 at khouzestan agricultural and natural resource research center in southwest of ahwaz in khouzestan province (iran) by position 31º20′ n, 48º40′ e. at first section for evaluation wet forage yield cultivars such as “baghdadi”, “mesasersa”, “yazdi”, “bami”, “nikshahri”, “synthetic” (main factor) and two cut...

The present investigation was undertaken to determine the biochemical changes associated with flower development during the flowering season in the potted carnation cultivars of ‘Lilac on purple’ and ‘Pink’. Ethylene production and the 1-aminocyclopropane-1-carboxylic acid (ACC) content of the flowers were observed to increase up to stage 5 (during the five stage of flow...

*Correspondence: Muhammad Iqbal, Department of Botany, Faculty of Science, Hamdard University, New Delhi, 110062, India e-mail: [email protected] Impacts of increasing environmental stresses (such as drought) on crop productivity can be sustainably minimized by using plant-beneficial mineral nutrients (such as sulfur, S). This study, based on a pot-culture experiment conducted in greenhouse c...

documenting the production process in agriculture includes providing all information and activities that shows the course of production from seedbed preparation stage to harvest stage. for this purpose, in present investigation all management operations performed from seedbed preparation stage to harvest stage in the studied wheat fields in 2007 and 2008 were recorded through farms survey. in t...
