Profitability assessment has prime importance for every crop husbandry practice and cultural operation. For this purpose, two field experiment was carried out to investigate the response of spring planted sunflower hybrids to different irrigation levels/schedules and foliar application of abscisic acid. Two studies were done at the Agronomic Research Farm, University of Agriculture, Faisalabad,...

Yield of some crops performs better in the intercropping than sole cropping system. Sunflower (Helianthus annuus L.) canopy is fragile providing a lot of ground cover, hence, therefore, has a great potential to intercrop with a short stature and/or duration crop making it comparable for the better net return in a cropping system. Field experiment was, therefore, expressly conducted to study the...

To satisfy the increasing demand for soybeans, identifying and sorting high-vigor seeds before sowing is an effective way to improve yield. Polarized hyperspectral imaging (PHI) technology here proposed as a rapid, non-destructive method detecting vigor of naturally aged soybean seeds. First, spectrum 396.1–1044.1 nm was collected automatically extract region interest (ROI). Then, first derivat...

to investigate the effects of sowing date on yield and quality of six forage maize cultivars in rasht region, a field study was conducted in 2010. the experimental design was a randomized complete block using a factorial arrangement with three replications. treatments consisted of four levels of sowing date (22 may, 3, 15 and 25 june), and six maize cultivars (sc 260, dc 370, sc 500, sc 647, sc...

The evolutionary approach called scatter search originated from strategies for creating composite decision rules and surrogate constraints. Recent studies demonstrate the practical advantages of this approach for solving a diverse array of optimisation problems from both classical and real world settings. Scatter search cont rasts with other evolutionary procedures, such as genetic algorithms, ...

this study was conducted at the gorgan university of agricultural sciences and natural resources farm, iran, golestan province with about 600 mm annual rainfall in order to evaluate the effect of different sowing dates on azivash (corchorusolitorius) seed quality, using a randomized complete block design with three replications on 2013. treatments were four sowing dates such as may 5, jun 5, ju...

in order to apply suitable methods for sugar beet seed sowing and determine the relation between yield and growth parameters in saline soils, two salt tolerant progeny lines were sown by five methods for two years (1995 and 1996) using a split plot design. growth parameters such as leaf area index, crop growth rate, total dry weight and relative growth rat were analysed. ph and ec of the soil a...

Fungal diversity in the soil may be limited under natural conditions by inappropriate environmental factors such as: nutrient resources, biotic and abiotic factors, tillage system and microbial interactions that prevent the occurrence or survival of the species in the environment. The aim of this paper was to determine fungal genetic diversity and community level physiological profiling of micr...
