Abstract
A field experiments were conducted during two successive growing seasons summer (2011) and winter (2011/2012) at Meet El-Deeba Farm, Kafr El-Shiek Governorate, Egypt to evaluate the using of some field wastes as mole drain filling materials to improve some physical and chemical properties and soil productivity as well as some water relations under maize and wheat crops. The experimental treatments were six treatments (control, unfilled moles and moles filled with sand, shredded rice straw, maize stalk or cotton stalk) arranged in a complete randomized block design with four replicates. The obtained results could be summarized as follow:
1- Soil bulk density (ℓb)and penetration resistance (PR) were decreased with different treatments as compared to control. The lowest values of these parameters were obtained under shredded cotton stalk filled moles. At the same time, soil porosity (E), basic infiltration rate (IR) and the rate of soil salinity (ECe) decrement were increased with different treatments, where shredded cotton stalk filled mole gave the highest values.
2- The total yield of both crops were highly significantly increased with different treatments, where the unfilled moles produced the highest maize yield increment rate, while cotton stalk moles gave the highest wheat yield increment rate, relative to the control.
3- The amounts of water applied, water consumptive use, crop and field water use efficiencies of both crops were increased with different treatments.
4- The net return for both crops were increased as a result of applying different treatments, where the highest net return value for maize was achieved with unfilled moles. While for wheat, the highest value was obtained with cotton stalk moles.
It could be concluded that the field wastes could be safely disposed through injection into the soil in moles with proper depth (50-60 cm). These moles seemed to be more effective in improving soil permeability and hence ameliorate saline clay soil and consequently increase crop productivity and helping for reducing pollution factors.
