"Plants slow their growth when they experience stress such as drought, a prolonged lack of sunlight, or any other low-energy circumstance. The discovery could help plant breeders create crop varieties that can continue to grow under stressful situations. "
"Net CO2 fertilization effect will be overestimated unless vegetation-climate feedback effects are taken into account."
"Increased levels of CO2 can enhance photosynthesis and reduce leaf-level transpiration. These changes can reduce growing seasons and water loss. The result could be an increase in what's called "crop water productivity".
“Using future climate data, simulation modelling allows researchers to develop hypotheses about future agricultural systems. This can help predict and proactively mitigate potentially catastrophic scenarios from challenges such as shrinking natural resources, climate change and the increasing cost of agricultural production.”
"Staple crops such as paddy and wheat self-pollinate, many vegetables and fruits rely heavily on external pollinators such as bees to reproduce. In the absence of these pollinators, productivity might decline as much as 80% for some plant species."
“If a farmer can clear his farm using a one-rupee matchbox, why will he spend thousands?”
"Not only were Bt cotton seeds 30 times more costlier than conventional seeds, the declining resistance to insect attacks was forcing farmers to use more and more sprays. Ultimately, the initial savings on pesticide use were wiped out. Besides, Bt cotton cost 7 per cent more than conventional cotton to grow but yielded 7 per cent less."
"The problem is if a farmer can clear his farm using a one-rupee matchbox, why will he spend thousands? "
