to study the effect of planting dates and genistein application on nitrogen content and nodulation of three annual medic species (medicago polymorpha cv. santiago m. rigidula cv. ragidula, and m. radiata cv. radiata), an experiment was conducted during 2005-2006 in the research farm of faculty of agriculture, shahed university, tehran. the treatments were arranged as split split plot in a rando...

Cowpea is one of the fast-growing legume crops during summer and well suited to environmental conditions in Egypt. In addition, it a high-quality crop for feeding sheep cattle, also very important fodder dairy cows. this study, an experiment was designed evaluate effect biofertilizers on cowpea productivity cultivated under sandy soil at Ismailia Governorate. To reach such aim, identified Strep...

In order to evaluate the different growing media and nitrogen fertilizer (urea) on some morphological traits of Spathiphyllum plant, an experiment was carried out in split plot arrangement based on completely randomized design in three replications in greenhouse conditions in 2018. The main plot consisted of different growing media including T1: Leaf-mold, T2: Vermicompost and T3: A mi...

Pyrethrum is a perennial daisy grown commercially for the insecticide that is extracted from its flowers. In order to evaluate germination and seedling growth of pyrethrum under different temperature and drought stress treatments, an experiment was conducted in seed technology laboratory of Faculty of Agriculture of Islamic Azad University of Isfahan branch in 2018. During this experiment, poly...

Legume/cereal intercropping has the potential to maximize use of resources raise yields due enhanced nitrogen (N) fixation by legume root nodules, while high N fertilization may inhibit nodulation legume. However, whether legume/cereal can promote accumulation soil storage with and its underlying mechanism are less clear. Here, we evaluated long-term (5 years) effects maize/peanut mineral on pe...

In vivo CO(2) fixation and in vitro phosphoenolpyruvate (PEP) carboxylase levels have been measured in lupin (Lupinus angustifolius L.) root nodules of various ages. Both activities were greater in nodule tissue than in either primary or secondary root tissue, and increased about 3-fold with the onset of N(2) fixation. PEP carboxylase activity was predominantly located in the bacteroid-containi...
