Influnce of growing fahl berseem on improving some properties and the productivity of newly reclaimed soils [electronic resource].

Includes references.

Two winter Fahl berseem field experiments were conducted in two newly reclaimed soils, at Ismailia and New valley Agricultural Research stations during (2009/10 and 2010/11) seasonsThis was to study the effect of planting methods and seeding rates on improving some chemical, physical and biological soil properties, as well as its productivity. The treatments comprised (1) Three planting methods Le., broadcast, 20 and 30 em distance between rows. (2)Applied three seeding rates, i.e., 20, 25 and 30 Kg seed fad" the experiments were laid-out a split plot design with three replicates. Results showed improvements for several soil chemical, physical and biological parameters ,i.e., soil pH , a.M, available N, P and K, bulk density, total porosity, available water. Dehydrogenase and nitrogenase activity as a result of the tested treatments refer to control (broadcast method under 20 kg seed fad") treatment. Drilling on 20 em apart as planting method was the best supporters in studied soil rroperties, particularly in the presence of 30 kg seed fad" treatment.
