Abstract

This research was conducted in order to distinguish the high yielding alfalfa, cultivars and for offering a distinct fertilizing formula, using split plot statistical design with four replications. Main factor was alfalfa by four cultivars (local of Salmas - Bonab Abi , Krysari , and Native) and six minor factor was fertilizer (P205), by six levels based on effective ingredients including zero, 15, 25, 35, 45, and 55kg/ha. The experiment was conducted in the dry - land condition of Meshgin village located at Km. 50, north - west of Zanjan, with average rainfall of 372 mm; since 1371, lasting for 5 years.Hay yield and height of the cultivars were measured from the 2nd year and means were compared statistically by Duncan method. In spite of non significant difference between main treatments, the local cultivar (Native) produced the highest amount of yield, totally 1959 kg/ha. during the whole period of experiment, and other mentioned cultivars i.e. Salmas, Krisari and Bonab Abi had average yield of 1630, 1491, 1441 kg/ha respectively. It is not worthy that, yield of main factor during whole years were followed the same rank, with the exception of year 1373, there were statistically significant difference (P<0.05), and complex analysis of variance resulted significant difference (P<0.01) between minor treatments (application of fertilizers). In response to different fertilizer levels, the most amount of hay yield for fertilizer b5 (45kg/ha effective ingredient) during the whole period of the experiment with average yied of 1871 kg/ha and the least amount of hay yield was related to fertilizer b1 (without fertilizer) during the whole period (except 1372), with average yield of 1462 kg/ha. Regarding the difference between the means of interaction effects (AB), (P<0.05) combination of local cultivar of alfalfa (native) with fertilizer response of b5 (45 kg/ha. effective ingredient) i.e, a4b5 with the average yield of 2204 kg/ha. was introduced as the most productive cultivar and fertilizer administration expected for native cultivar of alfalfa, This is advised for extension of cultivation in vast areas of dry lands in the region, it is one of the main results of the current research. There were significant differences between the yields of hay during the years, so that the 2nd year (1374), was the most productive year, averaging 2963 kg/ha. From the view point of the height, the local Salmas and native cultivars by 53cm height, and Bonab-Abi and Krysari by 49cm height were the taller and shorter cultivars. Actually the taller cultivars were those which produced higher yield. The most growth of tall cultivars was related to the year 1375 (3d year of harvesting) with 64cm height and the least amount was related to year 1376 with 38cm height.
