Abstract:
The present investigation entitled, “Effects of different herbicide doses of weed control measures on yield and yield attributes in maize crop” was carried out during 2021-22 at Shivalik Research Farm, SIPS, Dehradun, and Uttrakhand. The experiment was laid out in a Random Block Design with 7 treatments {T1 Un-weeded, T2 Hand weeding (20+40 DAS), T3 Atrazine 50% WP (0-3 DAS), T4 Alachlor 50% EC (0-3 DAS), T5Metachlor T6 Metribuzine & T7 2, 4-D (Etyal ester)} and three replications. Observation related to yield and yield attributes recorded that there were no significant differences in plant population initially and at harvest due to weed management practices, Maximum number of cobs per plant was obtained 1.65 in T4 Alachlor 50% EC (0-3 DAS), Maximum length of cobs per plant obtained 15.54 in T4 Alachlor 50% EC (0-3 DAS), highest grain yield was 3563.68 in T4 Alachlor 50% EC (0-3 DAS), maximum number of kernels per cob obtained 14.64 in T4 Alachlor 50% EC (0-3 DAS). Application of Alachlor 50% EC (0-3 DAS) has found to be most effective as well as perfect for exploiting the maximum grain yield. Therefore, it has observed during the field experiment during the present field experiments that application of Alachlor 50% EC (0-3 DAS) found fruitful because it not only control the weed density or weed population but also increase the yield of maize crops.
