Conservation-agriculture practices and weed-management effects on productivity, water and energy-use efficiency of rainfed pearl millet (Pennisetum glaucum)

A field experiment was conducted during the rainy (kharif) season of 2019 at ICAR-Indian Agricultural Research Institute, New Delhi, to study effect different tillage and weed-management practices on productivity, water energy-use efficiency pearl millet [Pennisetum glaucum (L.). R. Br.]. The laid out in a split-plot design, with main plot, viz. conventional (CT), zero (ZT), + residue (ZT R) 3 t/ha, weed management subplot, weedy check, hand-weeding (HW) 30 50 days after sowing (DAS), pre-emergence (PE) atrazine @ 0.75 kg/ha followed by (fb) post-emergence (PoE) 2,4-D kg/ha, PE, PE fb tembotrione 0.05 PoE, 0.075 0.10 PoE replications. performance ZT R significantly better terms grain (2.40 t/ha) stover yields (7.90 compared CT, but par ZT. Similarly, HW DAS resulted higher (2.53 t/ ha) (8.13 than other practices, kg/ ha PoE. Higher water-use (6.45 kg/ha-mm) recorded under among practices. Net energy output (111,046 MJ/ha) (11.9) were also control. Cultivating either 2 or found-energy efficient eco-friendly rainfed conditions for productivity.
