Sowing Dates and Molybdenum Foliar Application for Two Peanut Cultivars

Abstract

The study aimed to assess application efficiency of Mo doses through leaves in two sowing dates and different phenological stages on agronomic characteristics of two peanut cultivars. The experimental design was a randomized block with four replications, with the treatments arranged in a factorial design 2 x 2 x 6 x 2, being two cultivars (IAC Tatu and IAC 886), two sowing dates, six Mo doses applied to the leaves (0, 50, 100, 200, 400 and 800 g ha-1) and two application times (early flowering and early seed formation). Were evaluated the number of pods/plant, the number of grains/pod, the weight of 100 grains, the yield of grain, the pod production and protein, lipids and the Mo contents in the grains. The highest pod yields were obtained with sowing in November, for both cultivars. The IAC 886 presents a significantly higher production than IAC Tatu when sown in November. When the seeds were sown in March, the cultivars showed similar productions. Foliar application of Mo at flowering and pod formation did not affect the agronomic characteristics, protein and lipid contents in peanut grains. The increase in Mo doses increased the content of this micronutrient in the grains.

Interactive Effects of Molybdenum, Zinc and Iron on the Grain Yield, Quality, and Nodulation of Cowpea (Vignaunguiculata (L.) Walp.) in North-Western India

“…The present findings are concordant with previous studies, where Mo supplementation increased the Mo concentration in ‘ Le-Conte ’ pear [ 37 ], grapes (cv. Merlot) [ 38 ], peanut [ 39 ] and lettuce [ 40 ]. Togay et al [ 41 ] also reported the enhanced concentration of Fe, P, Mn, Cu and Mo in lentil ( Lens culinaris Medic.)…”

Peanut response to co‐inoculation of Bradyrhizobium spp. and Azospirillum brasilense and molybdenum application in sandy soil of the Brazilian Cerrado

“…Responses to the application of Mo in the peanut crop have been very variable in Brazil. Some studies have not reported increases in grain yield in the crop (Gericó et al., 2020; Rosolem & Caires, 1998; Soares‐Filho, Lazarini, Orioli‐Júnior, & Bernardes, 2020), although there has been a significant increase in nodulation and N uptake in peanut plants (Gericó et al., 2020). On the other hand, significant increases were obtained by Quaggio et al.…”
