Colorimetric methods for the quantitative determination of HA have gained prominence due to their simplicity, cost-effectiveness, and suitability for field application.

Vermicompost as an alternative substrate to peat moss for strawberry (Fragaria ananassa) in soilles culture.

Background: Consecutive droughts and quantitative and qualitative reduction of surface and underground water resources have caused an increase in greenhouse and hydroponic cultivation for most garden crops, including strawberries, in Iran. On the other hand, most of the inputs of greenhouse crops in Iran are imported. To possibility of replacing vermicompost with peat moss under hydroponic cultivation, an experiment was done in a split plot based on randomized complete blocks design in three replications in Isfahan (Iran) Agricultural and Natural Resources Research Center in 2019.

Determination of the most appropriate fertilizing method for apple trees using multi-criteria decision-making (MCDM) approaches.

Appropriate tree fertilization with essential nutrients is considered as one of the major factors in enhancing the quality and quantity of horticultural crops. The most efficient way to fertilize trees is to dig holes around the trunks and fill them with appropriate chemical and organic fertilizer. Doing this operation with mechanized methods reduces costs and increases productivity compared to traditional methods.

Aiming at low nitrogen leaching diets based on nitrogen fertilizer regulatory policy: A regional bio-economic assessment of the Zayandeh-Rud river basin-Iran.

Negative environmental impacts of nitrogen (N) intensive diets have triggered global debates on sustainable nitrogen management. Solutions such as dietary transitions, cropland reallocation and N Regulatory Policy (NRP) have been proposed to mitigate the adverse environmental impacts of N use in food production. However, there is still insufficient understanding of how NRPs could be designed to minimize negative environmental impact across diverse agro-ecological zones without sacrificing human dietary requirements.

The relationship between bovine blastocyst formation in vitro and follicular fluid amino acids.

Follicular fluid has been found as a possible source of metabolic predictors for oocyte competence, and it is conveniently accessible during ovum pick-up (OPU). We used the OPU procedure to recover oocytes from 41 Holstein heifers for in vitro embryo production in this study. Follicular fluid was collected during OPU in order to establish a link between follicular amino acids and blastocyst formation.
