The aim of the present study is to analyze dynamics microbiological changes white strawberry fruits (Fragaria ananassa ‘Snow White’) grown in a greenhouse under five irrigation and fertil¬ization regimes, stored refrigerated state determine their shelf life depending on influence cultivation time fruiting storage, determined by standard methods for analysis epiphytic microflora. It was found that compared initial state, period, increase fruit losses, total number microorganisms, molds,...
Climate changes and competition between agriculture other sectors for soil water resources usage that resource management obtains increasing significance. As a part of agricultural resource management the choice irrigation scheduling method influences yield, fertilizer use efficiency, energy consumption, cost-effectiveness, etc. This paper focuses on comparative analysis evapotranspiration-based tensiometer-based components cost-effectiveness. Using data from greenhouse experiment...
Managing water distribution in irrigation canals aims timely and needed quantity implementation of supplies to irrigated area without excessive spillage i.e. at reduced conveyance loss adequate use for the crops. This article analyzed existing management practice canal view efficiency. The study was carried out an main canal. operational evaluated by indirect quantitative approach. Hydraulic simulation model created using hydraulic software HEC-RAS. Changes conditions due structures along...
Siltation is a significant factor, affecting the efficient operation and maintenance of irrigation canals which influence hydraulic behavior economic benefits irrigation. In last 25 years tendency silting up at in Bulgaria observed due to following reasons: decreased area under irrigation, fluctuation supply, non-regime section, ”berming” canal, economic, crime safety situation. The large number available bed load permissible velocity formulas differences between obtained results enforce...
This study aims at investigating the impact of irrigationmanagementfor tomato (Solanumlycopersicum 'Big Beef‘) grown under drip irrigation with mulch in an unheated polyethylene tunnel-type greenhouse.The experiment was carried out Chelopechene experimental field Institute soil science, agrotechnologies and plant protection town Sofia, Bulgaria 2018.Four different levels have been served as treatment: T1 - full application rate 100% water requirements , T2 T3 treatments – irrigationwith 60%...
Emerging climate changes and rapidly growing demand for food are creating preconditions making water an increasingly valuable resource irrigation management assumed greater importance responsible essential role. This study uses CROPWAT 8.0 model by FAO to predict simulate crop requirements greenhouse tomato production in Chelopechene experimental field of the Institute soil science, agrotechnologies plant protection Sofia, Bulgaria. The main input data climatic data, data. simulation results...
