soil or water salinity is one of the major problems of agriculture in the arid and semiarid regions of the world, especially in iran. beside the salinity, reasonable canola production depends on nutrient supply so that increase in quantitative and qualitative yield is highly correlated with nutrients availability, especially nitrogen and zinc. in order to investigate the effects of the nitrogen...

The objective of the present study was to describe the trend of germination characteristics for a variety of canola ‘Okapi’ at different pre-soaking durations. For this purpose, seeds were placed in 250 ml of distilled water for 0 to 12h with intervals of 2h at room temperature. Each sample of seed was placed in Petri-dishes and germinated at the temperature of 25°C. Fitting logistic function o...

this study was conducted to investigate the effect of physical and chemical processing on crude protein fractions of two varieties of canola (okapi and modena) and safflower (62 and zarfan) seed using cornel net carbohydrate and protein system and on protein subunits using sodium dodecyl sulfate polyacrylamide gel electrophoresis. formaldehyde was used as chemical treatment, while toasting and ...

BACKGROUND Problem weeds in agriculture, such as Lolium rigidum Gaud., owe some of their success to their large and dormant seed banks, which permit germination throughout a crop-growing season. Dormant weed seed banks could be greatly depleted by application of a chemical that stimulates early-season germination and then kills the young seedlings. Fluridone, a phytoene desaturase-inhibiting he...

background and objectives. integrated weed management approaches can help to decline costs weed control and improve its condition. critical period of weed control (cpwc) is defined as the best time for weeding. if cpwc is recognized we can accurately use herbicides and prevent environmental pollutions. beginning and duration of cpwc despond on some agents such as crop and weed traits, environme...

Seed fatty acid (FA) composition, oil and protein (meal) was assessed on five canola (Brassica napus) varieties in 14 cropping environments in southern Australia, including several low rainfall drought-stressed environments. We modelled the relationship between seed quality attributes and growing season rainfall and temperature using a linear mixed model. Variance components for variety and yea...

This experiment was conducted to evaluate the effects of saturated and unsaturated fats in starter and grower feeds on performance and carcass parts of broilers. In this experiment 288 day old broiler chicks (Ross308 strain) were used in a completely randomized design for 42 days with 8 treatments in 3 replicates and 12 chicks in each replicate. The experimental groups included: T1) control gro...

Abstract A research was conducted to evaluate the impact of various nitrogen and phosphorus levels along with beneficial microbes enhance canola productivity. The carried out at Agronomy Research Farm, University Agriculture Peshawar in winter 2016-2017. experiment randomized complete block factorial design. study comprised three factors including (60, 120 180 kg ha-1), phosphorous (70, 100 130...
