scarce water resources is a worldwide problem, still for iran, a country predominated by an arid and semi-arid climate, water limitation is more severe than for many other areas of the world. a field experiment was conducted to investigate the impact of irrigation regimes on growth, grain yield and irrigation water use efficiency in maize (zea maize l.) in 2006 at the research farm, college of ...

water deficit stress is the most important environmental constraint for growth, yield and productivity of crops, including the oil seed crops. this study was aimed at studying the influence of differing irrigation régimes on growth, chlorophyll , proline and some antioxidants content along with grain yield, yield components and oil content of sesame genotypes using a 4-replicate split plot rand...

Work under this investigation included farm survey, extension, and research components using both the CLSU research station and demonstration farms. An experiment was conducted for the determination of optimal stocking sizes, considering the growth and survival performance of various sizes of fingerlings along with economic factors. Size #22 sex-reversed nursery phase fingerlings of Nile tilapi...

in order to investigate the effects of different levels of nitrogen and phosphorous fertilizers on flower yield , yield components and some quality components of german chamomile, a factorial experiment based on a randomized complete block design with four replications was carried out in the medicinal plant research farm of shirvan college of agriculture during growing season of 2007-2008. nitr...

Rice cultivation has been challenged by increasing food demand and water scarcity. We examined the responses of water use, grain yield, and water productivity to various modes of field water managements in Chinese double rice systems. Four treatments were studied in a long-term field experiment (1998-2015): continuous flooding (CF), flooding-midseason drying-flooding (F-D-F), flooding-midseason...
