“…Additionally 60 revealed that NPK fertilizers plus organic manure enhanced crop yields higher than NPK fertilizers alone or NPK fertilizers plus straw. However 61 , showed that using NPK NPs with organic manure increased growth, yield of maize. In addition, combination between foliar application KP NP S with soil application of mineral NP increased growth and yield of maize 29 .…”

Worldwide, maize (Zea mays L.) is considered an important food and fodder crop. compost as a soil amendment and potassium (K) could enhance the maize yield. Therefore, two field experiments were carried out in the two seasons 2017 and 2018 to study the effects of compost at three levels and four forms of potassium fertilization on the yellow maize hybrid 'Pioneer Sc 30N11' yield components. to conduct the field trials, a split plot system in three replications was established. Three compost levels (0, 5 and 10 ton/ha) were in the main plots, and four potassium forms (untreated, nano-potassium fertilizer, humic acid and potassium sulfate) were in the subplots. Plot size was 10.50 m 2 , with 5 ridges with 3 m length and 0.7 m width. The results indicated that the application of compost (as organic manure) and the potassium forms significantly affected the plant height, ear length, grains number/ rows, grains number/ear, 100-grain weight, straw and biological yields, grain protein and K contents in both seasons. Increasing the compost from 5 to 10 ton/ha increased the yield, its components, protein and K contents. The foliar application of nano-potassium followed by humic acid increased all the studied characteristics. The interaction between compost manure (10 ton/ha) and nano-potassium (500 cm 3 /ha) or humic acid (10 ton/ha) recorded the highest mean values for all parameters during both harvest seasons.

“…Due to the high cost of fertilizers, the amounts supplied to the crops should be sufficient and efficient to increase the yields and returns without environmental degradation. This can be achieved by establishing an optimal fertilizer application rate, as defined in both agronomic and economic perspective (Rop, et al,2019).…”

The application of nitrogen fertilizers allows increasing crop yields and partially increase the natural soil fertility. They have a negative influence on the environment due to the significant release of nitrogen. Hence, the technology for decreasing the N-release is proposed in this work. Obtaining of complex organo-mineral NPK fertilizers by encapsulating a carbamide granule with a phosphate-potassium shell with humates is the main aim of this work. The main tasks of this shell is slow release of the nitrogen and phosphate nutrients from the granules into the soil following the agrochemical needs of plants and prevention of soil pollution. The powdered components agglomeration of phosphate and potassium fertilizers with a small amount of liquid phase (plasticizer) allows forming a phosphate-containing coating on a carbamide core by means of the semi-dry method. This innovation allows organizing the production of such a product at the average enterprise with less capital investment. Carbamide prills, phosphate-glauconite concentrate, calcium and potassium ballast humate, and "Avatar" trace-element chelate complex were used in experimental studies. A preliminary assessment of the market prospects for such an innovation shows a high level of market attractiveness for all market participants: producers, consumers, and society.
