The continuing decline in water resources under the ever-changing climate compels us to re-orient our focus to a more sustainable practice. This study investigates the performance of wheat genotypes viz. HD-2967, HD-3086, HD-3249, DBW-187, and HD-3226 under well- and deficit-watered conditions for their root-traits, biomass and nitrogen accumulation and remobilization, and water use efficiencies, grown in PVC-tubes.

- Delayed sowing of maize hybrids can lead to lower yields due to poor root growth, nutrient uptake, and dry matter accumulation.
- In a study comparing five maize hybrids, timely sowing resulted in 16-19% higher grain yields and 12-25% higher stover yields compared to late sowing.
- Advanced hybrids AH-4271 and AH-4158 performed best in terms of grain yield, nutrient efficiency, and root growth, emphasizing the importance of sowing time and hybrid selection for maximizing maize productivity.
Article Synopsis
- Field experiments evaluated eight integrated crop management (ICM) modules over five years in a maize-wheat rotation, showing significant boosts in maize grain yield with CA-based ICM methods compared to conventional techniques.
- Results indicated that while wheat yields remained statistically similar across methods, overall system yields for maize equivalents were higher in the CA-based approaches that retained residues.
- The study concluded that adopting CA-based ICM can enhance crop sustainability, improve farm profits, conserve water, and positively affect soil properties in north-western plains.
