Paddy rice cultivation

The results of resreach showed that rice areas were not distributed relatively uniform in all districts and the rice yield had average level when compared with the other rice cultivation areas. Rice yields in Thai Nguyen province sharply increased from 4.87 tons/ha (2010) to 5.49 tons/ha (2020) with the slightly decreasing the rice areas, it is proved that the farmer was not concerned to increase the planting areas while they focused on rising the yield potential and quality.

Rice is one of the most important food crops in the world and mainly cultivated in paddy feld by transplanting seedlings. However, increasing water scarcity due to climate change, labor cost for transplanting, and competition from urbanization is making this traditional method of rice production unsustainable in the long term.

Worldwide feralization of crop species into agricultural weeds threatens global food security. Weedy rice is a feral form of rice that infests paddies worldwide and aggressively outcompetes cultivated varieties. Despite increasing attention in recent years, a comprehensive understanding of the origins of weedy crop relatives and how a universal feralization process acts at the genomic and molecular level to allow the rapid adaptation to weediness are still yet to be explored.

Agriculture plays an important role in rural development. Rice is the more popular staple food of more than 80 per cent of the world population. It contributes 42 per cent of the total food production in India. The present study is based on secondary time series data. The compound growth rates, instability and standard cost concepts were use for the present study. It concluded that the compound growth rates for area were positive for all most all the district of EVZ except Gondia. The growth rates of area were below one per cent indicates that paddy is the traditional crop in study area.

Rice cultivation is taken in flooded soil condition. This creates an anaerobic environment and harbours different group of anaerobes. The continued submergence of soil provides a reducing environment and effects a build-up of anaerobic ecosystem in which two unique processes namely methane emission and reductive transformation of nitrogen occur. But the role played by specific group of anaerobes with respect to nitrogen transformation is still obscure. A study was undertaken to assess the different groups of anaerobes in nitrogen transformation in flooded rice soils.

Bund formation is an important field preparation operation in rice cultivation. Presently, this operation is done manually. A low cost, tractor drawn bund forming and strengthening implement for paddy wetlands has been developed. Shear strength of the bunds formed is one of the parameters for assessing effectiveness of bunds. Shear strength were measured for the bunds formed using the developed tractor drawn wetland bund formers and compared with the manual bunds formed at three locations. The medium bund former was seen to impart more strength to bunds formed at Pullazhi kolepadavu.

Coastal Odisha is one of the most flood prone areas of India where the paddy crop in the wet season is often devastated by flash floods with an average productivity of only 0.5–0.8 t ha⁻ ¹. The present study showed that farmers preferred to cultivate low yielding traditional land races owing to their better flood tolerance and the unavailability of flood tolerant high yielding varieties (HYVs).

Rice (Oryza sativa) is the most widely consumed staple food especially in Asia which accounts for around 90% of the world's total rice production. In the country, it is staple food of more than 60 per cent population in India. Among the major paddy producing states, Odisha is one of the major contributor in national production. The agro-climatic condition of Odisha is also suitable for production of rice. It is mostly cultivated by broadcasting and transplanting methods during Kharif and only transplanted during Rabi season.
