On average, for 2016 and 2017, the yield of tomatoes in the control variant was 117.1 t / he. The greatest effect from the application of chicken manure in the experience obtained when using the maximum dose of 35 t/he. Increase in average yields for 2 years to control version was 79.5 t/he or 67.9%. The best result from the joint use of fertilizers and chicken manure is achieved when applying it at a dose of 25 t/he – 162,6 t/he or 138,9%, which is significantly more than in the optimal variant with chicken manure at a dose of 35 t/he - 71,0%.
