Abstract

A pot experiment was conducted at the greenhouse in El-Nobaria region. The objective of this work was to expose the role of soil conditioner application rate on the properties of sand and loamy sand soils, and on barley yield (Hordium Vulgare) variety Giza 123, as well. In other words, this work aims at throwing the light on the capabilities of soil conditioner so that it might be used as a vehicle for enhancing the physical and chemical properties, especially available moisture and soil fertility status, of a coarse-textured sandy soil and another loamy sand calcareous soil on hope to render these the properties of these soils good enough for plant growth especially under greenhouses or for nursery purposes. The first soil was taken from a farm at the indices 31º 17' 41'' N and 30º 02' 60'' E, while the second was taken at 30º 21' 29'' N and 30º 27' 39'' E. The former soil represents sandy soil, while the other loamy sand calcareous soil. In both locations, soil samples were collected from the 0-30 cm soil layer. Soil conditioner (Tezlien-N 7000) was thoroughly mixed with the soil at the rates of 0.125, 0.250, and 0.500 Kg /Ton by weight of the soil in the pots. Results reveal that, soil conditioner application lowered soil pH and increased soil EC, CEC, OM, and available NPK of both soils. It also increased of the emergence, chlorophyll a and b and yield parameter of barley in both soils. The soil conditioner was more profound in the sandy than in the sandy loam soil.
It can be concluded that increasing the rate of conditioner application to 0.25 Kg /Ton was the best for bringing about the best soil moisture characteristics; hence the best seed emergence and plant growth. This rate could also provide the most appropriate available water and soil fertility level then could produce the best grain and straw yields of barley plants.
