Grass pea (Lathyrus sativus L.) has a high potential for forage production inboth rangelands and cultivated rainfed areas of Iran. It is well adapted to semi-arid areas ofwest and north of country where annual rainfall is 250–350 mm. To study the seed and DryMatter (DM) yield and agronomic traits, six genotypes of Lathyrus sativus L. and twogenotypes of Lathyrus inconspicuous L. were provided b...

In order to investigate the diversity and relationship between agronomical traits with seed yield components in barley, twenty advanced barley lines were evaluated in a randomized complete block design with 3 replications at Research Center of Agriculture in Sistan in 2006. Each plot consisted of six rows spaced 20 cm apart and 5 meters long. In this research, 24 Agronomic traits were measured ...

The duration of pre-anthesis developmental phases is of interest in breeding for improved adaptation and yield potential in temperate cereals. Yet despite numerous studies on the genetic control of anthesis (flowering) time and floral initiation, little is known about the genetic control of other pre-anthesis phases. Furthermore, little is known about the effect that changes in the duration of ...

this research was assigned to study the top crop yield potential and nutritive value of jerusalem artichoke (helianthus tuberosus), using a completely randomized designed with three treatments and four replications. the forage was cut at three growing stages where plant high, fresh and dry forage yield and leave/steam ratio were recorded. first and second cut were made when the plant heights we...

Drought stress is one of the most important abiotic stresses in crops that can reduce yield and yield components in terms of time, duration and severity of the stress. Current research was carried out in order to evaluate drought stress tolerance in rice genotypes. Experiment done in two separate schemes using randomized complete blocks design with three replications in Research Field, Faculty ...

Two barley (Hordeum vulgare L.) forage varieties – Hemus and Karnobat, with high and low Rubisco content in the fully expanded first leaves (Metodiev and Demirevska-Kepova, 1992), were compared in pot vegetation experiments in respect of yield. Changes in the content of leaf pigments, the levels of total soluble and Rubisco immunoreactive protein were followed during six phenophases: 3rd leaf, ...
