Plant Breeding and Biotechnology

21.3K
Crop cultivation has a long history in human civilization, with records showing the cultivation of cereal plants beginning at around 8000 BC. This early plant breeding was developed primarily to provide a steady supply of food.

Key Elements for Plant Nutrition

23.8K
Like all living organisms, plants require organic and inorganic nutrients to survive, reproduce, grow and maintain homeostasis. To identify nutrients that are essential for plant functioning, researchers have leveraged a technique called hydroponics. In hydroponic culture systems, plants are grown—without soil—in water-based solutions containing nutrients. At least 17 nutrients have been identified as essential elements required by plants. Plants acquire these elements from the...

Transgenic Plants

8.3K
Recombinant DNA technology called transgenesis is often used to add a foreign gene or remove a detrimental gene from an organism. Such genetically modified organisms are called transgenic organisms.
The first-ever transgenic plant was a tobacco plant developed in 1983 that showed resistance against the tobacco mosaic virus. Since then, many transgenic plants have been developed and commercialized for improving the agricultural, ornamental, and horticultural value of a crop plant. Transgenic...

  • Nanotechnology
  • Plant Nutrition

Background:

  • Chemical fertilizers pose risks, including heavy metal contamination in crops.
  • Novel technologies are crucial for increasing agricultural yields sustainably.
  • Nanotechnology offers promising solutions for enhancing crop production and quality.

Purpose of the Study:

  • To evaluate the impact of nano chelated iron fertilizer on rice agronomic traits and yield.
  • To assess the efficacy of a novel nanochelating technology in fertilizer synthesis.
  • To determine the potential of nano chelated iron to reduce chemical fertilizer requirements.

Main Methods:

  • A randomized complete block experiment with 3 replicates was conducted.
  • Various treatments involved different timings and methods (foliar and soil application) of nano chelated iron fertilizer.
  • Control (T0) and multiple nano chelated iron application strategies (T1-T7) were compared.

Main Results:

  • Nano chelated iron fertilizer increased biological yield by 27% and protein content by 13%.
  • Hollow grain number decreased by 254% with nano chelated iron application.
  • Significant increases in nitrogen (46%), phosphorus (43%), potassium (41%), iron (25%), and zinc (50%) concentrations in white rice were observed.

Conclusions:

  • Nanochelating technology effectively enhances rice yield and nutritional value.
  • This technology can significantly reduce the reliance on conventional chemical fertilizers in agriculture.
  • Nano chelated iron fertilizer has the potential to bio-fortify crops with essential micronutrients, improving food quality.
