in order to study the effects of supplemental irrigation and planting arrangement on yield, yield components and water use efficiency (wue) of kabbuli chickpea (cv. arman), an experiment was carried out at the agricultural research station of gonbad for two years, iran. the experiment was a split-plot factorial arranged in a randomized complete block design with three replications. the main plo...

The effects of irrigation water salinity (12 dS m−), imposed at maximum tillering (35−40 days after sowing, DAS) or booting (50−60 DAS) or grain filling (75−85 DAS) stage of wheat, on growth and yield of the crop was demonstrated. The experiment comprised four treatments – I1: irrigation by fresh water (FW) at all three growth stages (control), I2: irrigation by saline water (SW) at maximum til...

In most wheat growing moderate regions and especially in the north of Iran climate, is affected grain filling by several physical and abiotic stresses. In this region, grain filling often occurs when temperatures are increasing and moisture supply is decreasing. The experiment was designed in RCBD with split plot arrangements with four replications. Four irrigation treatments included (I0) no i...

This experiment was conducted on NS Leviathan hybrids during the summer season under semiarid region. It designed as a split plot factorial arrangement using randomized complete block design (RCBD) with three replications. The purpose of this to determine skipping irrigating effect I1, I2, and I3 salicylic acid applied S1 non-applied S0 yield at growth stages (vegetative, flowering, achene-form...

in order to study effect of foliar application of iron and zinc on yield and yield components of autumn rapeseed (brassica napus l.) under limited irrigation an experiment was conducted at research farm of agricultural faculty of urmia university in 2009. the experiment was designed in split plot based on randomized complete block design with 3 replications. treatments were drought (irrigation ...

In order to investigate the effect of deficit irrigation and chemical fertilizers on yield some physiological traits quinoa an experiment was conducted in 2019 as split plot based a randomized complete block design two locations (Mashhad Neishabour). Irrigation included, I0: full irrigation, I1: no at emergence stage, I2: stem elongation I3: flowering I4: seed setting stage. Fertilizer treatmen...

BACKGROUND: Humic acid is a natural polymeric composition which is produced as a result of decaying organic matters in soil, peat and lignin to increase crop product. OBJECTIVES: Assessment the effect of different irrigation regime and humic acid on red bean production and correlation coefficient between measured traits. METHODS: Cu...
