Response of five different mixture or Range plants to irrigation intervals was studied for two years. Irrigation intervals included. 20,30,40,50,60
days and nil and the mixtures were as follows.
Mixture I Sainfoin,Bromegrass,Reed can¬arygrass, Intermediate wheatgrass.
Mixture II Sainfoin, Burnette, Wild rye, Russian Wild-rye Crested wheatgrass.
Mixtur III Alfalfa{Yazdi),Burnette,Cres¬ted wheatgrass,Russian wild-rye, White
clover
Mixture IV Tall fescue,Intermediate
wheatgrass,
Alfalfa (Cody), Reed Canary
grass, Fairway wheatgrass.
Mixture V Tall fescue, Bromegrass Cres¬
ted wheatgrass
Alfalfa (Hamadani) ,Sai¬
nfoin.
Some plots with no seeds were also incl¬uded.
In general increasing the interval between irrigation seems to decrease the
yield Per.unit area and this was more ap¬parent in the second harvest. Although dry
_. _ _
matter content did not show a constant trend to irrigation intervals but here
again this was much higher for the seco¬nd harvest than the first one.
The percent of grass dry matter was much higher in the 20-day interval
than others but a reverse case was obtai¬
ned for the legumes. This appears to be, in part, due to the different nature of
these groups of the plant in their respo¬nse to moisture.
20-day interval and to some extent 30¬
day,seems to be Promissing with
regard
to dry matter Production and the most promissing mixtures include different
combination of Alfalfa, Sainfoin, Brome¬
grass, wheatgrass Crested wheatgrass
species, particulary
and Burnette. They
will be studied in more detail in the
next year.
