Crop residue management has emerged as a major challenge in recent years. No-till wheat sowing, which aims to either incorporate paddy residue or retain it in the field, is one of the best technological measures to address this challenge. Therefore, a farmer participatory on-farm trial was conducted during 2020-21 and 2021-22 at five locations in Rohtak to validate no-till wheat sowing for resource conservation, paddy residue management and its impact on wheat yield and profitability. The trial consisted of four different wheat establishment methods: conventional sowing, zero till drill sowing, happy seeder sowing and super seeder sowing. The field study revealed that no-till sowing resulted in 75-80% reduction in fuel consumption and 10 - 25% savings in water during first irrigation. Zero tillage and happy seeder methods showed 40-45% less weed flora incidence, especially of Phalaris minor. The grain yield was 5.3% higher under the super seeder than the conventional method, while zero till drill and happy seeder sowing were comparable to conventional sowing. However, the B:C ratio (3.5) was significantly higher under zero till drill sowing. Thus, the participatory on-farm trials demonstrate the potential benefits of no-till wheat sowing for sustainable crop production and better economics in district.
