چکیده

in order to investigate the effects of different irrigation regimes and zeolit on the yield, yield componentsand relative leaf water content of sorghum, a field experiment was conducted in split plot in time andspace based on randomized complete block design with three replicates in research station of shahidbahonar university of kerman in 2011. irrigation regimes (100, 80, 60 and 40% of field capacity) anddifferent amounts of zeolite (control, 150 and 300 kg ha-1) were arranged as main and sub plots,respectively. irrigation regimes showed significant effect on all traits (fresh weight, dry mater, height,relative water content etc.) except stem node number. meantime, all the traits except stem height, relativewater content and the crop growth rate at the first and fourth stage of sampling affected by superabsorbent so that the highest amount of the measured traits were recorded for 300 kg ha-1 super absorbent.interaction effect of the irrigation water × sap × harvest was significant for fresh weight. the highestfw in second harvest belonged to i100 × 300 kg ha-1 sap. at the end, it can be concluded that applicationof 300 kg ha-1 super absorbent in irrigation levels lower than field capacity will result in 20% increase inyield.

Effect of Irrigation Regimes on Yield, Yield Components and Seed Quality of Different Pinto Bean (Phaseolus vulgaris) Genotypes

Identification of drought-resistant genotypes is crucial in order to reduce the negative effects of drought, as one of the most important limiting factors of crop production in arid and semiarid regions. Thus, effects of three irrigation regimes (irrigation after 50 (I1), 100 (I2) and 150 (I3) mm evaporation from a class A pan), as the main plot were investigated. These effects were studied on ...
