to predict growth and yield, it is needed to study sub-models of phenology, dry matter production and partitioning, leaf area and soil water balance. in the present study, for predicting yield of faba bean under gorgan conditions, parameters of sub-models were estimated using data of planting dates in gorgan and data of other researchers in different regions of world. daily variations of phenol...

lipids in liver wet and dry matter, liver moist and dry matter and their relationships were investigated based on species, sex and age in cows, buffaloes, sheep and goats. mean percentage of lipids in liver wet and dry matter and liver dry matter in cows were 3.60%, 1.10%, 29.70%, and for buffaloes were 5.30%, 1.55%, 29.20%, sheep 3.00%, 0.83%, 27.90%, and goats 2.910%, 1.55% and 28.40%, respec...

Dry matter intake (DMI) is fundamentally important in nutrition because it establishes the amount of nutrients available to an animal for health and production. Actual or accurately estimated DMI is important for the formulation of diets to prevent underfeeding or overfeeding of nutrients and to promote efficient nutrient use. Underfeeding of nutrients restricts production and can affect the he...

In this work, 75 quality protein maize (QPM) inbred lines were evaluated for aluminum tolerance using a nutrient solution assay in laboratory and soil-based technique greenhouse tunnel. The experiment was set up completely randomized design with three replications the laboratory, complete block used greenhouse. Aluminum toxicity generated by amending 600 µM of sulfate (Al2 [SO4]3) Al2 [SO4]3 ap...

Plant growth regulators (PGRs) are a common and widely used practice in cotton production for controlling plant growth, increasing yield, and improving management efficiency. Most of the PGRs used have an effect on plant growth, both vegetative and reproductive, and dry matter partitioning. However, there have been no reports of effects of PGRs on radiation use efficiency (RUE). It is logical t...

Greenhouse and field experiments with American ginseng (Panax quinquefolius L.) stratified seed sown at depths of 10 to 100 mm were carried out to determine effects of seeding depth on seedling emergence, growth and development and to calculate optimum seeding depth. The time to 50% seedling emergence (E50) in the field increased linearly from 17 d at 20 mm seeding depth to 42.5 d at 80 mm. See...
