The time-course of CO(2) assimilation rate and stomatal conductance to step changes in photosynthetic photon flux density (PPFD) was observed in Chrysanthemum x morifolium Ramat. ;Fiesta'. When PPFD was increased from 200 to 600 micromoles per square meter per second, the rate of photosynthetic CO(2) assimilation showed an initial rapid increase over the first minute followed by a slower increa...

A major challenge faced by alfalfa growers during the past 30 years has been the increased emphasis on forage quality. The need to produce high-quality hay affects marketing and price, as well as yield and stand life. Demands for high-quality alfalfa by the marketplace have been relentless. Although crop yield is still the primary economic factor determining forage crop value per unit of land a...

To evaluate the effect of plant density and detopping on grain yield, protein content biological yield harvest index, growth indices, number of cob in each plant, No. of row per ear, No. of grain in each row, thousand seed weight of corn (Zea mays L. ar. SC 704), an experiment was conducted at the experimental statues of Research Center of Uremia Agricultural College in 2004. The Treatment desi...

In the major wheat growing countries, wheat growth and yield are negatively affected by salinity and breed tolerant cultivars through selection and breeding techniques is necessary to solve this problem. Relationship among yield, and its related traits in 23 wheat cultivars and promised lines were studied under salt stress conditions using a randomized complete block design with three replicati...

Ammonia emissions and odor are being used to regulate animal produc­ tion. The objectives of this study were to observe the effects of restricted feeding dairy heifers high concentrate (HC) and low concentrate (LC) diets with different forage quality on NH3 emissions and odor. A split plot design with diet type as the whole plot and forage quality as sub­ plot was administered in a 4-period (21...
