Abstract:
A field experiment was conducted at Dinnabellur village, Dharmapuri district, Tamilnadu to during June 2021 to October 2021 to find an effect of spacing and weed management practices on irrigated hybrid maize. The experiment was laid out in Split Plot Design (SPD), the main plot treatments comprised of different spacing viz., 60 x 10 cm (M1), 60 x 15 cm (M2) and 60 x 20 cm (M3). The sub-plot treatments comprised of different weed management practices viz., Unweeded Control (S1), Twice hand weeding at 20 and 40 DAS (S2), Pre - emergence application of Atrazine 50% WP @ 1 Kg a.i. ha-1 on 3 DAS (S3) and Pre emergence application of Atrazine 50% WP @ 1 Kg a.i. ha-1 on 3 DAS + One hand Weeding on 30 DAS (S4).
A field experiment was conducted at Dinnabellur village, Dharmapuri district, Tamilnadu to during June 2021 to October 2021 to find an effect of spacing and weed management practices on irrigated hybrid maize. The experiment was laid out in Split Plot Design (SPD), the main plot treatments comprised of different spacing viz., 60 x 10 cm (M1), 60 x 15 cm (M2) and 60 x 20 cm (M3). The sub-plot treatments comprised of different weed management practices viz., Unweeded Control (S1), Twice hand weeding at 20 and 40 DAS (S2), Pre - emergence application of Atrazine 50% WP @ 1 Kg a.i. ha-1 on 3 DAS (S3) and Pre emergence application of Atrazine 50% WP @ 1 Kg a.i. ha-1 on 3 DAS + One hand Weeding on 30 DAS (S4).
Among the different spacing and weed control treatments, M3S4 (spacing of 60 × 20 cm along with Pre-emergence application of atrazine 50% WP @ 1.0 kg a.i ha-1 on 3 DAS + one hand weeding on 30 DAS excelled over other treatments by recording higher values of g yield components at harvest such as Number of grains cob-1 (529), Cob length (26.32 cm), Cob diameter (6.55), Grain yield (6390 kg ha-1), Stover yield (10224 kg ha-1) and this was on par with M3S2 (spacing of 60 × 20 cm along with two hand weeding on 20 and 40 DAS). This was followed by Pre-emergence application of atrazine 50% WP @ 1.0 kg a.i ha-1 on 3 DAS (M3S3). M1S1 (spacing of 60 × 10 cm with unweeded control) recorded the highest weed counts and weed biomass resulting in very poor grain yield (3085 kg ha-1).
Hence, from the experiment revealed that M3S4 (spacing of 60 × 20 cm along with Pre-emergence application of atrazine 50% WP @ 1.0 kg a.i ha-1 on 3 DAS and one hand weeding on 30 DAS was the efficient method of weed control which produce highest grain yield and reduce the nutrient uptake by weeds and higher economic returns. M3S4 (spacing of 60 × 20 cm along with Pre-emergence application of atrazine 50% WP @ 1.0 kg a.i ha-1 on 3 DAS and one hand weeding on 30 DAS was efficient and economically viable agronomic practices to manage the weeds and get higher yield as well as economic returns from hybrid maize.
