Effect of magnesium fertilization on some plant nutrient interactions and nut quality properties in Turkish hazelnut (Corylus avellana L.)

Abstract

Plant nutrient interactions and fertilization is one of the most important factors affecting the quality of hazelnuts. This study aimed to determine the relationships between some plant nutrients and some hazelnut quality criteria and yields. ; however, because of the recent interactions, the available phosphorus and potassium of the soil decreased to 84.28 and 298.24 mg kg -1 significantly. The total yield was increased to 1747.05 kg ha -1 with 150 kg ha -1 magnesium fertilization. The protein quantity in the kernel was not changed but there was important increased in oil content, kernel ratio, shelled and kernel nut weight and healthy nut amounts, and also was decreased in the amount of empty and wrinkle nuts were identified. Although the total yield increased with increasing amount of magnesium fertilizer (200 and 250 kg ha -1 ), especially the phosphorus and potassium interactions were increased in the soil, and also some nut quality properties such as kernel ratio, shelled and kernel weights, total oil, healthy nuts, empty and wrinkle nuts were be getting worse.

Magnesium Fertilization Improves Crop Yield in Most Production Systems: A Meta-Analysis

“…Mg 2+ plays a critical role in regulating photosynthesis (Sun and Payn, 1999); Mg deficiency severely down-regulates photosynthesis rates, photo assimilates transport to sinks and crop yield (Nèjia et al, 2016). Magnesium application promoted Mg concentration in leaves ( Figure 3A) and crop yield (Figure 2).…”

“…Magnesium (Mg) is an essential element for crops, animals, and humans, the deficiency of which affects photosynthesis and carbohydrate partitioning in crops (Nèjia et al, 2016), reduces sustainability of agricultural production and development, and causes long-term negative impacts on human and animal health (Robert and Helen, 2004;Jeroen et al, 2015). Unfortunately, obvious symptoms of Mg deficiency frequently occur in crops, especially at their critical developmental stage with rapid carbohydrate accumulation, grown in acidic soils widely distributed across the world (Cakmak et al, 1994;Nèjia et al, 2016). Edible agricultural products are the main source of Mg nutrition for humans and animals.…”
