limitations of water and nitrogen in soil usually restrict plant growth. the objective of this study was to evaluate the effects of different amounts of supplemental irrigation at different growth stages and application of different rates of nitrogen fertilizer on grain yield and water productivity of wheat cultivars. a field experiment was conducted in the agricultural research station of shah...

Background & Aim: Black seed or black cumin (Nigella sativa L.) belongs the family Ranunculaceae. Black seed is one of these species, which is naturally distributed in different parts of the country. It is extensively cultivated in various regions of Iran.  Experimental: The experiment was achieved using randomized complete block desi...

two field and laboratory experiments were conducted to investigate the effects of superabsorbent polymer (sap) and irrigation management on seed and essential oil yields of cumin, as well as the impact of water quality on water holding capacity of sap. salinity had a negative effect on the amount of water absorbed by sap (335 and 59 g h2o per g sap, for distilled water and solution of 0.5% nacl...

drought, specially in reproductive stage is one of the major constraints, limiting the productivity of crops, including chickpea (cicer arietinum l.). to study the effects of drought during pod set and seed filling stages (terminal drought) on phenology, growth and seed yield of 5 kabuli chickpea genotypes of: arman, jam, hasham, flip93-93 (azad) and ilc482, an experiment was conducted during t...

We utilized a proteomic approach to investigate seed development in Medicago truncatula, cv Jemalong, line J5 at specific stages of seed filling corresponding to the acquisition of germination capacity and protein deposition. One hundred twenty proteins differing in kinetics of appearance were subjected to matrix-assisted laser desorption ionization time of flight mass spectrometry. These analy...

Drought, particularly terminal drought, reduces the yield of chickpea (Cicer arietinum L.). Terminal drought tolerance and water use patterns were evaluated under controlled conditions in 10 genotypes of desi chickpea. Withholding water from early podding reduced vegetative growth, reproductive growth, seed yield, and water use efficiency for seed yield in all genotypes. The genotype Neelam, wh...

BACKGROUND AND AIMS The duration of the plant life cycle is an important attribute that determines fitness and coexistence of weeds in arable fields. It depends on the timing of two key life-history traits: time from seed dispersal to germination and time from germination to flowering. These traits are components of the time to reproduction. Dormancy results in reduced and delayed germination, ...

Profiles of adenylate and nicotinamide nucleotides in soybean seeds were determined during seed-fill. The ATP content per seed increased during the early seed-filling stages to a level of 10 to 12 micrograms per seed. Seed ATP decreased after 40 days of development and reached its lowest level of less than 1 microgram at maturity. The ATP:ADP ratios were relatively constant at all seed developm...

To study the effects of both drought stress and seed zinc and iron concentrations on the photosynthesis, chlorophyll fluorescence, and proline and carbohydrate accumulations in soybean (Glycine max (L.) Merr. cv. M9) leaf, a split plot experiment was carried out in 2012 based on a randomized complete block design with three replications in greenhouse conditions at Yasouj University. Drought str...
