Effect of different rates of farmyard manure and plant spacing on growth, yield and quality of jerusalem artichoke plants under sandy soil conditions [electronic resource].

Includes references.

Two field experiments were carried out dUring two successive summer seasons of 2008 and 2009 at the experimental farm, EI-Kassasein Research Station, Ismailia Governorate, to investigate the effect of different rates of farmyard manure (10,20,30 and 40 m'/fed), plant spacings (20,30,40 and 50 em) and their interactions on vegetative growth, fresh and dry weight, yield and its components and cihemical constituents of Jerusalem artichoke plants (He/ianthus tuberosus L.) cv. fuseau under sandy soil conditions. Farmyard manure at a rate of 40m³/fed. recorded maximum values of plant height, number of shoots /plant, fresh and dry weightl plant, and increased number of tubers per plant, average tuber weight and yield / plant as well as cihemical constituents of tubers as compared with 10m³/faddan. Planting Jerusalem artichoke plant at 50 em reflected the highest values of vegetative growth parameters, yield and yield components as well as chemical constituents of tubers. The best interaction treatment between different rates of farmyard manure and plant spacing was fertilization with 40m³ farmyard manure in combination with the highest plant spacing (50em) as compared with other treatments.
