In-house Experiment on Ryegrass in Pots - Jan 1 2024 to March 30 2024

  1. Introduction: Si is known to prevent water loss. Many users of Aquaritin 19 have commented on lowering of wilting point and less hand watering when using the product. This study was designed to understand the impact of Aquaritin 19 on water use efficiency (WUE).
  2. Preparation: A soil blend of 70% loam soil with 30% vermicompost was created for this experiment by thoroughly mixing the two and filling them up to 75% mark in 10 pots. Ryegrass seeds were soaked in muslin cloth and placed in a dark location for three days to facilitate proper germination. Once germinated, the seeds were planted in the pots at a depth of 1-2 cm on 6th January 2024 and adequately watered. After two months of successful growth under glasshouse conditions, the Ryegrass turf pots were deemed ready for use. 

Experiment Design: A total of 10 pots were prepared and were not irrigated for a 10-day period between 5th March and 15th March. 

Control: 2 pots not irrigated between 15th March and 30th March 

Irrigated: 2 pots each irrigated with 100ml of well water every 3 days between 15th and 30th March 

Aquaritin 19 250ppm: 2 pots sprayed with 250 ppm of Aquaritin 19 on 15th, 20th, 25th and 30th March – No irrigation

Aquaritin 19 500ppm: 2 pots sprayed with 500 ppm of Aquaritin 19 on 15th, 20th, 25th and 30th March – No irrigation

Aquaritin 19 1,000ppm: 2 pots sprayed with 1,000 ppm of Aquaritin 19 on 15th, 20th, 25th and 30th March – No irrigation
