Project Description
Location: Volgograd Oblast, Southern Federal District.
Goals:
- 1) Improve nutrition of vegetable crop grown under fertigation (with fertilizer application through drip irrigation).
2) Optimize fertilizer expenditures when growing field vegetable crops under fertigation.
- 1) Study the response of field vegetable crops to such new fertilizers for fertigation as Calcium Nitrate, Ammonium Chloride, and Ammonium Sulfate Nitrate.
2) Study the effect of new fertilizers for fertigation on quality and marketable yield of field vegetable crops.
3) Study the effect of new fertilizers for fertigation on soil properties.
4) Study the effect of foliar fertilization in tomato.
Measurements in field experiments include: irrigation water quality, wide range of soil analysis prior to and after irrigation, crop phenology, yield components, yield (marketable and total) and its quality, dry matter accumulation and nutrient removal in the harvested and unharvested portion of crops, water use efficiency.
