Abstract
This Technical brief is a short summary of the results obtained from the laboratory and field trials conducted by Climarice project team, Tamil Nadu Agricultural University, Coimbatore, Tamil Nadu, India to evaluate the potentials of microbial inoculants (biofertilizers) such as Blue Green Algae, Azolla and Phosphobacteria in minimizing the impacts of climate change in rice cultivation by nutrient supplementation, methane emission reduction and carbon sequestration. Cyanobacteria (Blue green algae) as a biofertilizer for rice in supplementing nitrogen is highly promising as the rice field ecosystem provides congenial environment for this self supporting diazotroph. Azolla is a floating water fern that also fixes atmospheric nitrogen. Azolla and Cyanobacteria have been identified as eco-friendly natural nitrogen fixers in the rice field ecosystem. A judicious use of these blue green algae could provide entire rice acreage of India as much nitrogen as obtained from 15-17 lakh tonnes of urea. Cyanobacterial nitrogen fixation helps to minimize the over dependence of chemicals, in particular, urea in rice farming and also enhances the use efficiency of nitrogen by releasing ammonia constantly to the rice crop.
Abstract
Adapting to changing climate is essential for individuals and communities to sustain their livelihoods. Improving adaptive capacity at various levels is essential, and this can be done by strengthening ongoing initiatives, introducing new measures, training and capacity building. One of the main focus areas of the Climarice projects is to train the farmers on implementing various adaptation technologies that would increase the water and nutrient use efficiencies at field level. Climarice project scientists have identified various technologies such as usage of biofertilizers such as blue green algae and azolla to improve the nutrient use efficiency in paddy cultivation, application of green manures to enhance soil organic matter content, introduction of short duration rice cultivar during delayed monsoon, cultivation of alternate crops for income generation, System of Rice intensification for enhancing water and grain productivity, usage of bio control agents such as Trichoderma and Pseudomonas for eco friendly management of pest and diseases etc.,. For the successful implementation of these technologies at field level, the farmers have to be given with training and exposure visits. ClimaRice project scientists have undertaken many capacity building programmes to farmers of Cauvery basin on various adaptation technologies and these programmes have created confidence among the farmers. Many farmers who have attended the training programmes are following the technologies with great interest. A summary of the training programmes and their impact are furnished in this report.
