| Abstract | ||||
| The study was carried out at the Horticultural Research station of Barrage region during summer seasons of 2000 and 2001 on Jerusalem artichoke Local and Fuseau cultivars on plant growth, tuber yield and tuber chemical constituents. Three organic manure levels. l.e 10.20 and 40mJ FYM/Fen and nitrogen sources. i.e (NH4)2 SO. and NH4 Nol. The Local cultlvar showed higher fresh weight offoliage, No. of branches, No. of main stems in contrast to plant height. Tuber yield 01 Fuseau cultivar was 14.76 and 15.48% higher than that of the Local one during 2000 and 2001 respectively. Fuseau and local cunivars growth parameters responded pos'lively with the increased levels of organic manure application up to 40m3 FYM/Fed; during 2000 and 2001. Results also indicated lhat Fuseau cultivar tuber yield and inulin content increased as FYM level elevated from 10, 20,40 ml FYM/Fed as compared to local cultivar, during 2000 and 2001. Application the form of (NH4)2 S04 increased fresh weight of foliage and greater number of branches, number of main stems. and tuber yield by 6.63 and 22.80010 more than that NH. N03 during 2000 and 2001, respectively. local cullivar tubers showed greater total carbohydrate and total sugar, tolal protein, lotal nitrogen and lotal potassium, compared with Fuseau cullivar Fertilization with 40m3 FYMlFed Also. (NH.i)2 S04 increased inulin con enlration. carbohydrate, total sugar. totat protein and NPK content application with 40m~ FYM/Fed and 40 Kg NJFed (NH4h S04 were the optimum rates to maxmlze luber yield and quality of the local and Fuseau Jerusalem anichoke cultivars. | ||||
