Abstract : To study the forage and grain production dynamics of triticale, a trial was c arried out having four genotypes planted on three different dates under irrigated conditions at Dera Ismail Khan, Pakistan (31o49’53”N 70o54’7”E). All the four genotypes were of different pedigree/parentage background. Trial was laid out in split-plot design with genotypes in main plots while dates of sowing in sub-plots. The trial was replicated three times. First date of sowing started with planting the genotypes on Oct. 25 (T1) followed by Nov. 15 (T2), and Dec. 05 (T3). All the genotypes planted at each date were harvested 50 days after planting. The results showed that the earliest planting produced significantly the highest green forage yield, maximum plant height and grain spike-1. However, grain yield remained similar statistically when planted the Triticale on different dates. Comparing the results of four genotypes studied, it was observed that each genotype behaved significantly different for green forage yield, days to 50% heading, plant height, tiller m-2, grains/spike, 1000-grain weight and bio-mass yield. Genotypes 3 and 4 produced maximum green forage yield i.e. 3.70 and 3.65 t ha-1, respectively, however differences among the four genotypes for grain yield were found non-significant statistically. Net Photosynthesis Rate and Chlorophyll content recorded for all genotypes and dates of sowing remained similar statistically. The highest Benefit-Cost ratio (3.23) was calculated for gynotyp-4 when planted on the earliest dates i.e. Oct-05. It was, however, observed that net benefit decreased with delay in each planting date irrespective of the genotypes
