Aerobic paddy

These methods have lengthy process and difficult to scale up, hence a simple method of nanofertilizer production amenable for large scale production and testing its applicability in crop production can help for upscaling this futuristic technology. With this background, research was undertaken to synthesize urea coated hydroxyapatite nanofertilizer for enhanced nitrogen use efficiency and its filed testing using aerobic rice as test crop.

The widely adopted Alternate Wetting and Drying (AWD) irrigation for rice production is increasingly needed to investigate for assessing nitrogen fate in the soil. An experiment was conducted under aerobic soil conditions to study Nitrogen (N) transformations. The simple numerical analytical model used to simulate urea, ammonical nitrogen (NH4-N) and nitrate nitrogen (NO3-N) concentration in experimental plot. Simulation of urea concentration decreased as 2 %, ammonical nitrogen and nitrate nitrogen concentration increased as 9 % and 9.8 % compared to observation.

Composting is carried out under aerobic thermogenesis to prepare a selective substrate for Agaricus bisporus production. Conventionally, wheat straw based synthetic compost is used for its production. Use of paddy straw as such tends to make the composting process anaerobic leading to low quality compost and low yields. In the present study, an alternative high yielding compost formulation based on paddy straw + maize stalks as a substitute to the existing wheat straw based compost has been made.
