Seed priming with iron and zinc improves growth and yield of groundnut (Arachis hypogaea L.)

Abstract

Seed priming is considered as an important component that results in early establishment of crop seedling. Thus, the effect of seed priming with iron (Fe) and zinc (Zn) on growth and yield components of groundnut (cv. BARI-2011) was evaluated by using different doses of Fe (0.1% and 0.3%) and Zn (0.5% and 1.0%) in RCBD design with two factors factorial arrangement having three replications. The crop was grown in April, 2016 at the Research Farm of PMASArid Agriculture University, Rawalpindi, (Pothowar Pleatue) Punjab, Pakistan. Data revealed that plant height and number of plants were highest at 0.3% Fe in combination with 1.0% Zn. Similarly, numerical values for all measured yield components i.e., number of pods plant -1 , kernel weight (kg ha -1 ), 100 kernel weight (g), pod yield (kg ha -1 ), biological yield (kg ha -1 ), harvest index (HI) and shelling percentage were significantly higher at 0.3% Fe in combination with 1.0% Zn as compared to the control. The control plot resulted in the lowest values for all the parameters studied. It can be inferred from the results that seed priming at the rate of 0.3% Fe in combination with 1% Zn is recommended for obtaining higher yield of groundnut.

Potassium Fertilization and Micronutrients Foliar Spray Effects on Peanut Productivity and Its Export Traits Using Giza 6 and Nc 9 Peanut Varieties, in Sandy Soils

“…Moreover, results in Table ( 5) reveal that in unfertilized potassium plots (control), peanut plants sprayed with micronutrients outyielded significantly unsprayed one in fodder yield/fad and that was true in the two seasons. Ayman and Fawzy (2014) and Khan et. al.…”

Melatonin induces drought tolerance by modulating lipoxygenase expression, redox homeostasis and photosynthetic efficiency in Arachis hypogaea L

“…Groundnut seeds primed with gibberellic acid exhibited higher antioxidant activity, proline, lesser malondialdehyde and higher chlorophyll content under salt stress ( Erbil, 2021 ). Zinc and iron priming significantly enhanced the yield of field-grown groundnut ( Khan et al., 2017 ). Seed priming with several agents (gibberellic acid, hydrogen peroxide, salicylic acid, ascorbic acid and so on) improved the salinity tolerance of the groundnut plants ( Pal et al., 2017 ).…”
