بررسی ارزیابی عملکرد علوفه و دانه ژنوتیپ های پیشرفته خلر در مزارع زارعین در منطقه گرمسیر

Increment of world population day to day led to more trying with researchecs to increase crop productions. Our success will be related to transfer of finding research to farmer's field. To do this and transferring new technology to farmers field and to evaluation of advanced lathyrus sativus lines at farmer fields, 7 advanced lines with Naghadeh local variety as check were used for comparing these lines to check in respect of grain yield, forage yield(fresh and biomass). To do this, lines were planted in 3 locations of Dehdasht, Sarabnaniz and Likak using randomized compelet block design with 3 replications in 4 rows with 5 meters length and 25 cm spacing from each other (plot area was 5 square meters) via labors in the favorite time at 2009-2010 growing season. During growth season, agronomic data were recorded from some important agronomic traits. loss of trials in the dehdasht and likak regions due to harvesting them by local agricultures, data after maturity have not been recorded and in the sarabnaniz region we have a compelet dtat. Results of simple analysis of variance in the sarabnaniz area for wet forage, biomass and grain yield showed that the difference of lines were significant only for wet forage at the 5% probability level.About wet forage, line No. 1, 2, 3, 4 and 6 in the A class with the 9.668 t/ha, 9.667 t/ha, 9.539 t/ha, 9.961 t/ha and 9.621 t/ha repectevily were placed at the highest level. About biomass and grain yield all of lines were located at the A level that line No 6 with the 3.293 t/ha biomass and line No. 2 with the 1.567 t/ha grain yield were detected as the best lines. In the dehdasht and likak area, the differences among lines were not significant at the probability levels. Although line No. 2 with the 8.340 t/ha and 6.440 t/ha respectevily have the highest amounts. Results of combine analysis for wet forage showed that the location effect was significant at the 1% probability level. Line effect was significant at the 5% probability level, but line* location intraction effect was not significant. Finnaly, with consideration wet forage and field observation line No. 2 Sel 474 with the wet forage in the all of location and 27.91% yield increment with chack (Naghadeh) could be released to farmer's fields with extension office.
