Government of India Introduced fortified rice to poor under various schemes
Fortified rice to poor under various schemes
- This decision was taken in order to address the problem of malnutrition in India.
- Providing nutrition to every poor person India is a priority of the government.
- This decision was taken in the view that, malnutrition and lack of essential nutrients among poor women and poor children is a major hurdle in their development. This, government will provide fortified rice with nutrition them.
- Child Malnutrition is a major threat to the growth and development of children.
- Micronutrient deficiencies or ‘hidden hunger’ also continue to pose significant public health problems in Indian populations.
- This announcement is significant because, government distributes more than 300 lakh tonnes of rice under schemes covered under National Food Security Act (NFSA), 2013.
- Food fortification is the simplest and sustainable public health strategies that address the challenge of micronutrient deficiencies. It is a cost-effective, scientifically proven, and globally recognised approach. It also helps in easily reaching to wider & vulnerable populations by means of existing food delivery systems.
Because, rice has highest uptake in government food safety net programmes like public distribution system, integrated child development services, mid-day meal schemes etc. Further, rice has potential to reach more than a million people, especially women and children.
According to National Family Health Survey report, India has the largest burden of iron-deficiency and anaemia worldwide. About 59% of children and 50% of pregnant women are anaemic in India. Child and maternal malnutrition accounts for 15% of India’s total disease burden.

- Ploughing is opening of compacted soil with the help of different ploughs.
- Ploughing is mainly done to open the hard soil.
- Optimum range of soil moisture for effective ploughing is 25 to 50% depletion of available soil moisture.
- Light soils can be ploughed in wide range of soil moisture conditions while the range is narrow for heavy soils.
- Depth of ploughing depends on the effective root zone depth of the crops.
- Crops with taproot system require greater depth of soil, while fibrous, shallow rooted crops require shallow ploughing.
- In heavy soils 3 to 5 ploughings are needed.
- In light soils 1 to 3 ploughings are required.
- Country plough is used for multiple purposes.
- Disc plough is used for cutting of creeping or spreading grass and inversion.
- Tractor drawn mould board plough used for deep ploughing and inversion.
- Animal drawn mould board plough is used for incorporation of manures, fertilizers and plant residues. 1 cm of surface soil over one hectare of land weighs about 1.50 t.
- In western countries deep ploughing is 50cm depth for rainfed conditions 70cm for irrigated conditions
According to CRIDA,
- Shallow ploughing: 5-6 cm
- Medium deep ploughing: 15-20 cm
- Deep ploughing: 25-30 cm
- A deep tillage of 25-30cm depth is necessary for deep rooted crops like pigeonpea.
- Moderate deep tillage of 15-20 cm is required for maize.
- Residual effect of deep tillage is marginal.
- It is advisable to go for deep ploughing only for long duration, deep rooted crops.
- Cotton roots grow to a depth of 2m in deep alluvial soil without any pans.
