HERE IS 1972 INFORMATION OF IMPORTANCE TO YOUR RICE-PRODUCTION DECISIONSþ A check mark indicates items that apply NOW -- in 1972. Other items give the newest research findings on the shape of future developments designed to keep the California rice grower economically healthy in the business of farming.
FEATURED THIS YEAR - NEW-VARIETY PROGRESS AND RESIDUE MANAGEMENTþ CS-M3 RANKED AS A TOP-YIELDING VARIETYThis new smooth-hulled medium-grain variety has proved to be a topyielding variety broadly adapted for use north of Stockton as a replacement for Calrose. At the West Side Field Station it yielded slightly but not significantly lower than Calrose. It threshes well, is free of hairs on the hulls, and the mill head yield equals that of Calrose. þ CS-S4 IS ANOTHER POTENTIAL REPLACEMENTThis smooth-hulled pearl variety will compete with Caloro. In 1971 it equaled Caloro in yields in tests at Davis, Robbins, and the West Side Field Station. Over several years of testing at Biggs, Willows, and Escalon it has outyielded Caloro by 6%. Foundation and registered seed is available to growers. ASSURED STANDS GETTING CLOSERTraditional rice-growing methods are not yet outmoded, but the day nears as research seeks to outmode seed soaking and assure good stands from the initial seeding. In experiments, coating seed with an oxygen-yielding compound made it possible to drill or sow from the air and then flood. For now, the compound is scarce and expensive, and technical problems remain. WINTER NURSERY SPEEDS SCREENING AND BREEDINGVariety development time is reduced by growing new selections in Hawaii. Grown this past winter were 6,000 selections and 200 rows for seed. An additional SO lines were increased in Puerto Rico. Only the highlights of the total program of California rice research are summarized here. To cover new information for your operations in the fewest words, no distinction is made between the work by the various organizations:
