Abstract The rising population is increasing food demand, yet actual crop production limited by the poor efficiency of classical fertilizers. In particular, only about 40–60% fertilizer nitrogen, 15–20% phosphorus and 50–60% potassium are used plants, rest ending polluting environment. Nanofertilizers promising alternatives. Here, we review plant nutrients, synthesis zinc oxide nanoparticles, e...

The application of organic fertilizers alone or in combination with bio-fertilizers is important for sustainable agriculture, healthy agricultural production and restoring soil quality. Compost, vermicompost and mycorrhiza amendments could improve soil quality and plant yield. However, little is known about their impact on yield and quality of European borage (Borago officinalis L.). To evaluat...

Azolla mycrophylla, Cherry leaves and tea waste are organic materials that have potential as liquid fertilizers because they able to bind nitrogen from the air contain high potassium. In manufacture of fertilizers, bioactivators such bamboo shoots needed accelerate fermentation process. The purpose this study was determine content N, P, K elements sensory tests on fertilizer (POC) combining myc...

This research set out to evaluate the effect of combined biological and chemical nitrogen fertilizers on some corn hybrids. To this end an experiment was conducted as split plot on the basis of randomized complete block design with four replications. Main plots were included: use of chemical and biological fertilizers in four levels: 100% chemical fertilizer, 75% chemical fertilizer + 100% bio-...

This experiment was conducted to determine the effects of nitrogen and phosphorus fertilizers on nutritive value of safflower forage and silage by in situ and in vitro methods. The safflower forage was harvested at flowering stage, chopped to 3-5 cm particles and then ensiled in the laboratory silos for 60 days. The experimental treatments included: 1. Unfertilized forage (control), 2. Phosphor...
