abstract in order to investigate the effect of irrigation and nitrogen fertilizer, on yield peanut plant, with furrow method of irrigation and water use efficiency (wue) in management to create a proper and better production, split plot experiment was over taken as in complete randomize blocks with three replications and main plot with 6, 12 and 18 day interval irrigation and no irrigation and ...

the periwinkle with the scientific name of catharanthus roseus is one of the most important ornamental plants of the apocynaceae family. in order to evaluate the effect of different waters on the amount of the nutrient elements in soil and aerial parts of catharanthus roseus, a factorial experiment based on completely randomized design was conducted in 3 replications. experimental treatments we...

Traditional water-saving irrigation management turns on water pump in a settled interval decided by grower’s experience. The method just saves water on the back of losing yield. In order to result the problem, a kind of greenhouse efficient irrigation management system based on Evapotranspiration has been developed. The system includes greenhouse environmental monitoring subsystem, irrigation a...

in order to investigate the effect of irrigation intervals and harvesting time on yield and yield components of anise (pimpinella anisum l.) a field experiment was conducted at the agricultural research station, university of zanjan in 2010. for this purpose a spilt-plot experiment based on complete randomized block design with three replications was used. three irrigation intervals (every 7, 1...

Water scarcity is an important obstacle to the development and expansion of urban landscape in the arid and semi-arid regions of the world. Nowadays organic and artificial materials can be used to reducing water consumption without reducing the quality and quantity of urban landscape. In order to study of the effect of some mulch type on the reduce of irrigation interval on a popular seasonal p...

subsoil compaction, may occur naturally or a consequence of machinery traffic, causes reduction in crop yield. the aim of this work was to characterize the effects of subsoiling and irrigation on yield of corn. this study was conducted on the silty loam soils of miyandoab agricultural research station on the base of split plots design with 12 treatments and 4 replicates during the 1999 and 2000...

using mulch to decrease and optimize water use, increase yield and fruit quality is known as a practical method. for this purpose, a split-factorial experiment based on complete block design with three replications on two melon cultivars was conducted in torbat-e-jam, iran. interval irrigation treatments in three levels (six, eight and 10 days) were considered as main plot and mulch (rice straw...

this study was carried out in the agro-industry complex of gohar kouh, khash in iranshahr. a split-plot experiment based on rcbd was employed with three irrigation intervals including 1: 30 day interval 2: 40 days of irrigation interval 3: 60 day irrigation interval along with three levels of nitrogen application including 1: no nitrogen fertilizer 2: 750 grams of nitrogen fertilizer per tree 3...
