Lethbridge Herald, The (Newspaper) - August 20, 1971, Lethbridge, Alberta _ IETHBRIDGE HF.RAID Friday, August 20, 1971 BUSineSS NeWS Alberta farming, ranching, dairy, poultry IRRIGATION PROBLEMS An old wooden structure., poor waler ccnlrol and canals in poor condilion are somr1 of rhe problems lo bo overcome by a ihree-year upgrading program in me St. Mary River Irrigation district. On this particular seclion, 34 drop and check structures like this one will have to be replaced with cement slruclures in a 15-mile span. The slructures allow ihe waler lo be lower- ed in one area so ihe canal bed grade can be maintained for a distance. Corn breeding program develops new varieties for irrigation land Water use near record SMRD is complex system Hj filC SW'IIIAIIT Kami ICilitur IL is a huge, cosily, expan- sive tiling, il involves many many more men and affects and it handles more water than most tilings. What is il? In this case ii is an irriga- tion system in general and the St. Mary River Irrigal i o n District in particular and the best way to see it is lag along li Jake Thicssen, manager, on one of his checking trips. The district started 1971 oper- ations the c-nd of April when waler slarlcd flowing e a s I from the St. Mary and Water- ton Dams inlo Ridge Hcservoir south of Raymond. The water is controlled by the Prairie Farm Rehabilita- tion Administration until it is in Ridge Rcservor where SMRD takes over all the way lo Medicine Hal. The Taber Irrigation Distinct interrupts Ihe SMRD for short distance. Totally, SMRD has wa- ter u s e r s irrigating acres of land and another -100 people who get water for vary- ing uses, including home use. Mr. Thiesscn said the district is now into a major refurbish- a I already linal and another BW miles will be finished in the Spring of 1972. "The cement presents a self- cleaning ditch which requires very little he said, "and the waler moves program which includes construction of cement lined canals.

The first step will lie Ihe de- velopment of inbred lines, said Mr. M. D. MacDonald. a cvlo- geneticist at Ihe Lel.hljridge Research Slalion. ''The selection of promising inbred lines may extend five to si.x generations." he said. Then these inbred lines will be tested in a large number of combinations lo find cut which ones arc most likely to produce the best symbolic va- rieties for Hie region. "We're aiming for e.T'ly ma- turing, high yielding said Dr. Mac-Donald.

The scientists are also work- ing wilh two old varieties call- ed Saskatchewan While Flint and Howes Early Alberta. Next year scientists plan to include early maturing lines; from the corn breeding pro-' grams in Mexico, South Am- erica and the I'.S.S.R. "This material will give us a wide genetic base on which lo build our breeding said Dr. MacDonald. "When Ihe first varieties emerge from the project, there will be a new business oppor tunity for Alberta farmers. Only firsl-generation seed is the true hybrid, and new seed must be produced each year. This is done by specialized growers, so hybrid seed pro- duction will develop as another industry in the area. The commercial crop can be used by processing industries lo make products such as corn starch and liquor, and by farm- ers as a livestock feed either as grain or silage. Dr. MacDonald said Ihe breeding program is designed lo produce synthetic varieties first and hybrids later. "A syntholic variety i.s like an open pollinated variety, ex- cept the breeder chooses (he original lines that go to make up the variety." Seed of synthetic varieties costs less than hybrid seed, hut yields are lower than the bel- ter hybrids.

Rbizcsphcre microbes act ns a Ivclogical sieve, allowing some sub- stances to rnlcr the plants while excluding olbers: they also bring about changes in the substances moving lo the root by releasing nutnc-iiLs useful to the plants and converting in- jurious substances to harmless compounds. The rhizo.sphcrs also may act as a biological barrier lo olhcr microorgan- isms that -jsease.

We h.v.e found tbm the plant selectively controls the rhizos p h e i1 e microorganisms and that the or kinds nf microorganisms that in the rhizosphcrc can be filtered by genetically changing the wheat plants. This genetic nl- teration is accomlished by sonieM from one variety cf for those of another. In our study one variety, extreme- ly susceptible to common rnot rot. was crossed with a resis- lanl The progeny car- rying llio genes for resistance I from Ihe second parent had an important controlling influence I over the microorganisms in the rhizoiphere.

However 20 per cent of the bacteria in the rhi- 7osplu-re of Ihe i (anl parent prcduccd lies inhibited the root-rot [uni'iis. The .same c-ffin-t v. us found in (lie of plains containing the sulvtilu- tcd pair. These re- sults indicate' that controlling I he- genetic m cf plants can result in changes in the soil rhizosphere that will improve plant growth or prevent injury Hail activity usually falls off rapidlv in Aueiist. and t h i s I year appears to be no cxcep- I Lion. I j Hail has been reported in the- Alberta Hail Studies project area on only three days in the first half of the month. South of Calgary there was even less, wilh some spotty small hail on only days. Since the hail season is near- ly over, the Alberta Hail 1 Studies is nnw gradually pha.s- ing out various operations. The cloud seeding aircraft re- turned lo Ottawa last weekend j after cm eight week stay in AJ- 1 her! a. During this period a loLa] of eleven cloud seeding experi- ments were carried out at widely separated locations with- in Ihe project area. The main effort during the last two months lias been 10 collect as mudi data as possible on all storms both seeded and un- seeded. All of this information is now being checked and cata- logued prior to the detailed an- alysis which will commence as soon as Ihe staff have moved back to Edmonton in Septem- ber. The radar Penhold will he kept running until end of this week. The last week in August will be spent packing all the equipment away for the winter before the summer as- sistants return to university. In order to keep the clima- tology of hail in Alberta up-to- date, all hail occur r e n c R a should still be repirteri right through to mid-September by mailing in the special report cards.

The record I second flowing past a given faster preventing a build-up of aquatic weeds which is a real problem in Ihe old style ditches in some areas. "The aquatic weed problem is getting worse this year, mainly because there is water running in the canals all sea- son and the hot spells have been longer this year." He said there are some dit- ches where the weeds are so thick the waler stops running and if chemical or mechanical methods arc used to rid Hie ditches of the weeds, they grow back in just a few days. "They grow back just about as fast as we can kill them in some areas." A major construction prob- lem, caused by a lack of money is the replacing of drop and check structures in many loca- tions. A drop and check structure allows the water lo drop lo a new level in one area, allow- ing the grade o[ the canal bed to be maintained between checks. "These structures control the speed of the water and also the condition of the canals and on the NrJ lateral between the Stewart elevators and the Northeast Reservoir, a distance of 15 miles, there are 34 struc- tures which must be he said. "They will cost an average of each and the district has the job planned for the next three years depending on the government policy re cost-shar- ing. "If the government will main- tain the present cost sharing schedule, the program will able to be completed." He said there won't be much work on the distribution of wa- ler lo the fanners because of the lack of funds. "We mist start wilh the big canals and work to improve the total sys- tem all the way to the farm. "It would be useless to have big farm ditches all over the place if the main irrigat i o n system was too old to get the water to the farm." Mr. Thicssen said the peak water useage is past, with su- gar beets, potatoes, corn and pasture the only major water users. All the grain fields and most of the hay fields are finished for Ihis year. With the weather as hot and the precipitation as low as this year, 1971 will have to rank as one of the years with the hea- viest drains on the irrigation systems in the south. From April 27 lo Aug 3, SMRD ran acre feet of water through its system. An acre foot is enough water to cover one acre of land (208 lee; by 208 feel) to a depth of one foot at any given lime.
