Sowing of wheat in left optimum moisture through zero tillage technology not only provides a good germination but also improves the soil fertility, soil physical properties and saves time hence increases net return on sustained basis. It causes minimal disturbance of soil structure and texture ultimately increases size of soil aggregates. In the present experimental study, genotypes and tillage effect was observed. The investigation was done with six different genotypes and two different tillage operation. Zero-tillage decreases the cost of production and saves time for sowing of wheat as compared to conventional tillage. Content of NPK in grains under zero tillage was N (1.44%), P (0.46%), and K (0.28%), while that of conventional tillage NPK content in grains was N (1.44%), P (0.45%), and K (0.28%). The minimum tillage and direct drilling system is energy and cost saving and environmental friendly reducing the soil pollution as compared to conventional tillage practices. In case of conventional tillage system thermal conductivity, bulk density and compaction of soil increases due to use of heavy agricultural machinery which reduces infiltration rate, soil porosity and plant growth. Among the six various cultivars (BRW 3708, CBW 38, DBW 39, HD 2967, HD 2733, K 0307), the best result was observed in BRW 3708 in terms of nutrient uptake in grains (kg/ha) as well as in nutrient uptake in straw (kg/ha). Zero tillage is superior over conventional tillage because higher yield were recorded on zero tillage farms than that of conventional tillage wheat farms in addition to its edge of eco-friendly practice.
