In order to investigate the effect of dehydration stress and planting date on some physiological indices and growth of Cymbopogon citratus, a field experiment in the form of a split plot in a randomized complete block design with 3 replications, including 3 levels of different irrigation (100% full irrigation as a control, 75 and 50% full irrigation) and 3 levels of planting date including 20 M...
In order to study the effect of drought stress on some growth indices of oil sunflower cultivars, a study was conducted in Isfahan. The experiment was conducted as split plots in a randomized complete blocks design with three replications in Isfahan (51° 48' E, 32° 40' N).Main plots were drought stress in four levels (80, 100, 120, and 140 mm evaporation from evaporation pan class A and cultiv...
Field experiments were conducted to evaluate plant population and N-fertilizer effects on yield and yield components of maize (Zea mays L.). Three levels of plant populations (53000, 66000, and 800,000 plants ha⁻¹ corresponding to spacings of 75 × 25, 60 × 25, and 50 × 25 cm) and 4 doses of N (100, 140, 180, and 220 kg ha⁻¹) were the treatment variables. Results revealed that plant growth, ligh...
A field experiment was conducted during the winter (rabi) seasons of 2015–16 and 2016–17 at Punjab Agricultural University, Ludhiana, to study effect staggered sowing on growth indices, photosynthetic parameters productivity barley (Hordeum vulgare L.) in relation different cutting management. The laid out a split-plot design with 3 dates, viz. 15 October, 30 October November main plots 5 manag...
One of ways to cope the drought stress is using tolerant plant and water preservative materials in the soil such as zeolite. Hemp is one of drug and oilseed plants.To evaluate the effect of zeolite in the modulation of deficit irrigation stress and improve the function and growth indices of Hemp, an experiment was conducted as split plot in a randomized completely block design with three replic...
A field experiment was carried out during the 2013-2014 growing season in Lorestan Province (Iran) to evaluate the effect of three planting densities (30, 55, and 83 plant.m-2) on growth indices and grain yield of four chickpea cultivars (Azad, Hashem, Arman and ILC482) under the fall dry land farming condition. The experiment design was factorial based on a randomized complete block design (RC...
In order to investigate the growth responses of sugar beet plant to drought stress and foliar application of proline at different growth stages, a field experiment was conducted as split plot arrangement in a randomized complete block design with three replications at the field Research Station of Shahrekord University during 2015. Main plot three level of irrigation treatments (100% (control),...
in order to study the yield and growth indices of spring safflower as double cropping, an experiment was carried out in 2007 at the research farm of faculty of agriculture, yasouj university, iran. the experiment was a factorial based on randomized complete block design with three replications. factors included of combination of four sowing dates (may 16, june1, june 16 and july 2) and four cul...
This study was conducted to evaluate the effects of water stress on growth indices and phenological traits and growth indices of Thymus kotschyanus during 2010 and 2011 growing seasons. A field experiment was carried out with three irrigation regims (T20, T50 and T80 representing irrigation after 20, 50 and 80% soil water depletion, respectively) using a randomized complete block design with f...
introduction lentil with about 28 percent protein occupies the second after soybean. it is one of the major crops in developing countries as a complement to cereals and is an excellent source of protein and amino acids in the diet. results of studies shown that for most crops, including lentil, the occurrence of drought stress in some phenology stages cause irreparable damages to yield. therefo...
