Abstract

Conventional tillage (CT) consumes a lot of energy and causes problems for soil and environment. Strip tillage (ST) is an alternative method to save environment and soil structure. A complete randomized experimental design was conducted. Two treatments with three replicates each were applied. They were T1 polwed conventionally and T2 plowed by ST. A strip tillage prototype was fabricated. Results indicated that there was a significant difference between T1 and T2 on SOC% and total soil N after harvest. SOC% and total soil nitrogen increased by 19.38 and 8.5% for T2 compared to T1. Fuel consumption was less in T2 by 46.7% compared to T1. There was a significant difference between grain yield of T1 and T2. Grain yield of T1 increased by 8.04% compared to T2. Also, there was a difference between T1 and T2 in water consumption. T2 saved about 5.75% of water compared to T1. Applying ST per one million feddan planted by maize crop allover Egypt saves 5.76 million tons of CO₂ and 18.316 million kg of N₂O which contributed into greenhouse gases. Also, T2 saves about 15.75 milion liters of fuel and 2.32 billion m³ of water per one million feddan.
