Study the Impact of Vermicompost, Zinc and Iron on the Performance of Hybrid Maize (Zea mays L.)

Abstract

A field experiment was conducted on student instructional farm (SIF) of Chandra Shekhar AzadUniversity of Agriculture and Technology, Kanpur, U.P. during kharif season 2019 and 2020, the present experiment having 32 treatments replicated thrice in factorial randomized block design on same laid out at same location. Hybrid maize variety Pioneer 3377 was sown at 60 × 20 cm (row×plant) during both the years, Soil application of Zinc (5.0 kg) and Iron (10 kg) along with 2.5 tonne vermicompost ha-1 gave significant increase (except plant population) in plant population m-2 (9.23 & 9.26), Plant height (195cm & 198 cm), number of cobs plant-1 (1.80 & 1.82), number of cobs m-2 (18 & 18) over control during 2019 and 2020.

Effect of foliar application of chemical fertilizers on morphological traits, antioxidant enzymes, and proline content of maize (Zea mays L.)

“…In the present study, the activity of antioxidant enzymes (leaf catalase, polyphenol oxidase of leaf, silk and seed and silk peroxidase) was affected by zinc, which indicates high absorb of zinc in the treatment. Also, the enzyme activity index con rms this issue, showing the direct role of zinc in gene expression and the synthesis of enzyme proteins (Pandey et al, 2022). In a study, the application of zinc enhanced activity of catalase in leaves of durum wheat and Kavir cultivar compared with the control treatment ( Pandey et al, 2022).…”

In a study, the application of zinc enhanced activity of catalase in leaves of durum wheat and Kavir cultivar compared with the control treatment ( Pandey et al, 2022). Nitrogen de ciency increased production of free oxygen radicals as well as improved activity of antioxidant enzymes to neutralize these free radicals (Zhang et al, 2016).…”
