FORAGE AND GRAIN PRODUCTION OF DUAL PURPOSE TRITICALE GROWN UNDER MOROCCAN CONDITIONS
Journal Title: International Journal of Agricultural Science and Research (IJASR) - Year 2017, Vol 7, Issue 1
Abstract
The use of triticale for feed is expected to be increased depending on the release of suitable varieties. The main objective of this study was to identify productive and suitable triticale material intended for dual purpose use under Moroccan climate and soil conditions. 50 advanced accessions of hexaploid triticale were tested for vigor, earliness, biomass and grain yields. Selected accessions were compared to barley, rye and triticale cultivars for forage and grain productions. Field trials were conducted at El Koudia farm in Morocco (34°03' N, 06°46' W) with varying defoliation regimes (uncut to grain yield, cut at erect leaf stage and cut prior to last leaf emergence. Yielded dry matter ranged between 0,96 and 2,74 t ha-1 respectively for early and delayed cutting. Four accessions yielded high forage such as barley, rye and triticale cultivar Juanillo. Forage removal had a depressive effect on grain yield for which losses reached 11% for early clipped genotypes and were of 32 to 73% when accessions were defoliated later. Grain and straw yield losses reported to forage harvested at vegetative stage indicated that genotypes E12, E18, E19, E20, Juanillo and barley cultivars gave the best compromises and were the most adapted to clipping.
