Abstract
Two field experiments were carried out during two successive winter seasons at 2013 and 2014, in a private farm at Abuo-Hammad area, Sharkia Governorate, Egypt, to evaluate the integrated fertilization management i.e. chemical fertilization (NPK), biofertilization (Rhizobium leguminosarum. bv. vicieae, Glomas bagyarajii, Bacillus circulans) with or without foliar applications of yeast extract (Saccharomyces cereviseae) and micronutrients on enzymes activity, nodulation status, growth characteristics, chemical constituents, mycorrhizal infection (%) and yield of pea (Pisum sativum L.) cv. Master B grown under loamy sandy soil conditions. All estimated parameters were affected by biofertilizers application, especially in combination with foliar applied with yeast extract. The highest values of the most studied parameters were recorded in combination between biofertilizers with foliar application of micronutrients and yeast extract.
Highlights
Pea (Pisum sativum L.) is one of the most important leguminous vegetable crops grown during winter season in Egypt for local consumption and exportation
This study aimed to evaluate the integrated fertilization management used in the current study for enhancement growth performance, chemical constituents and yield of pea
Data showed that the highest values of all estimated parameters, i.e. N, P, K and total protein in pea seeds were observed in plants inoculated with biofertilizers in combination with foliar application
Summary
Pea (Pisum sativum L.) is one of the most important leguminous vegetable crops grown during winter season in Egypt for local consumption and exportation. The pods of pea contain a great amount of protein and carbohydrates. That pea is considered as one of the most important sources in human nutrition. Fertilizers come in two types; they are either chemical or biofertilizers. Chemical fertilizers play an important role on plant growth and productivity. Nitrogen is essential for synthesis of chlorophyll, enzymes and protein. Phosphorus is essential for root growth, phospho-proteins, phospholipids and ATP, ADP formation. Potassium plays an important role in the promotion of enzyme activity and enhancing the translocation of assimilates and protein synthesis [15]
