Effect of gypsum, mycorrhiz and municipal solid waste compost on grain characteristics and antioxidant enzymes activity of peanut in the field cultivation

Peanut is rich in protein and energy and is used in most countries to supply nutritional needs. In this study, the effect of gypsum, municipal solid waste compost and mycorrhiza on grain characteristics and catalase and peroxidase activity of peanut during two cultivation years were investigated in a factorial split-plot design. In the first cropping year, the maximum number of pods (121.33 per plant), seed length (22.07 mm), thousand seed weight (117.92 g), number of seeds (156.33 per plant) and yield Seed (13746.2 kg/ha) were obtained with the use of mycorrhiza and no application of gypsum and compost, application of 150 kg/ha of gypsum with mycorrhiza and without application of compost, without mycorrhiza and application of 6 ton/ha of compost and with mycorrhiza, no gypsum and 4 ton/ha of compos, respectively. In the second cropping year, the highest catalase and peroxidase activity (36.18 and 92.26 unit/mg of protein), calcium and iron content (7.45 and 88.57 mg/kg), oil percentage (76 54%) and protein percentage (27.62%) were obtained with mycorrhiza, application of 150 kg/ha of gypsum and 8 ton/ha of compost, despite mycorrhiza and no application of gypsum and addition of 8 ton/ha of compost, no application of gypsum , despite mycorrhiza and application of 4 ton/ha of compost and despite mycorrhiza and application of 150 kg/ha of gypsum and 2 ton/ha, respectively. In this study, the simultaneous use of municipal solid waste compost and mycorrhiza is proposed.
