e0“A field experiment was conducted during rainy (kharif) seasons of 2019 and 2020 at ICAR-Indian Agricultural Research Institute, New Delhi to monitor the effect of precision nitrogen (N) and water management options on yield and nutrient acquisition in grain and straw of direct-seeded rice (DSR, basmati) (Oryza sativa L.)”
e1“Conventional till-direct seeded rice produced 1.9, 3.1 and 5.7% greater grain yield, grain protein content and protein yield, respectively, over ZTDSR; the respective improvement in grain N, P and K uptake was 5.9, 7.9 and 4.9%”
