Study of physicochemical, cooking and nutritional properties of promising rice varieties of Tamil Nadu

Identification and characterization of crop varieties are crucial for ensuring the genetic purity of seeds. The present investigation was carried out to identify suitable chemical methods that are fast, reliable and easy for seed analysts, breeders and seed producers for identification of a variety. Twenty-five popular rice varieties in the seed supply chain of Tamil Nadu were subjected to phenol, modified phenol, NaOH, aroma, gelatinization temperature (alkali spreading value), GA3 and 2,4-D tests. The results of the experiment revealed that phenol and modified phenol tests changed the colour of TKM 9 and TRY 1 variety to brown but no colour change was observed in the variety I.W. Ponni variety. The NaOH test is useful for the identification of TKM 9 variety as it changed the colourless solution to red. GA3 and 2,4-D tests characterized the varieties based on the shoot growth into two and three groups respectively. However, all the variety lacked aroma and exhibited a high gelatinization temperature.

Rice (Oryza sativa L.) which belongs to the family poaceae, is the life and the prince among cereals as this unique grain helps to sustain two thirds of the world's population. India have traditionally been used or rice cultivation due to availability of water and conductive soil (Nadesa panic). Rice was grown in 155.30 million hectares and around 600 million tonnes of rice harvested each year globally. About 114 countries produce rice with China and India supporting 50 per cent of total production. India stands first in area under cultivation (41.85 mha) and ranks second in production, where as China ranks first in production with just half of the area. India's production is 89.13 million tonnes with a productivity of 2130 kg/ha. Among the rice producing states of India, Tamil Nadu ranks sixth in production (6.53 million tonnes) and second in productivity of 3918 kg/ha with an area of 20.16 lakh ha (Season and Crop Report, 2012). Local farmers in such farming systems retain the traditional varieties based on their knowledge of the quality of the rice varieties and their adaptation to varying agro-ecological situations created by diverse seasons and land situations (Tapasi das & Ashesh Kumar Das, 2014). Among the major micronutrient deficiencies common in rice consuming countries, iron and zinc deficiencies (“hidden hunger”), affect over three billion people worldwide, mostly in developing countries (Welch & Graham, 2004).

Traditional Rice

This study investigates the risk behavior of traditional rice variety growers in Erode District of Tamil Nadu state, using Moscardi and De Janvry approach and Discriminant analysis technique. A well structured questioner was prepared and purposive random sampling was done in three blocks which covers highest cultivable area under paddy namely Gobichettipalayam, Modakurichi and Bhavani in Erode district. Each traditional rice varieties have some unique characteristics i.e some are pest and disease resistant, drought resistant, resistant to waterlogged condition and have medicinal values. The present study was done to identify the major risks, to quantify the risk attitude and to identify the factors influencing risk attitude of the traditional variety growers in Erode District. In the research it was found that the varieties preferred by farmers were Thuyamalli, Kichadi samba, Karuppukavuni, Mapillai samba,Arcaud Kichadi Samba, Poongar, Thanga Samba, Sivan Samba and few other varieties they were cultivating in small areas using organic farming method.The major risk found in cultivating traditional rice varieties were market risk followed by human labour risk, processing risk, input risk, technology risk, institutional risk, natural risk and other risks include transport risk and storage risk. The farmers were grouped into three categories i.e., risk preferrers (63.33 per cent), risk neutral (28.33 per cent) and risk averse (8.33 per cent) based on risk attitude. Once again the farmers in each group was categorized into low, medium, high risk based on nine factors namely, farmers age, major occupation, years of schooling, family size, membership in any of the farmers association, proportion of paddy area to total farm area, proportion of paddy income to total farm income, experience and adequacy of market which were influencing the risk attitude of farmers. In order to conserve the traditional rice varieties from extinction, to restore the soil health, to ensure nutritional security the farmers were willing to take risk.

A study was conducted to evaluate the Protein status of White and Brown Rice grain in selected varieties at Anbil Dharmalingam Agricultural College & Research Institute, Tiruchirappalli of Tamil Nadu, India during the period from June 2017 to May 2019. In the present study, sixteen different rice varieties cultivated in and around Tiruchirappalli district of Tamil Nadu as the test rice grains in terms of White and Brown rice in completely randomized design with three replications were tried. Screening and evaluation of protein content in 16 rice varieties were carried out to identify protein rich varieties. Biochemical analysis based on five different traits including contents of albumin(Alb), globulin(Glo), prolamin(Pro), glutelin(Glu) and total or gross grain storage protein (GGSP) were carried out. Results showed that the relative contribution of Albumin as 0.9 to 2.3 g/100 g, globulin as 0.67 to 2.3 g/100 g, prolamin as 0.28 to 2.73 g/100 g and glutelin as 2.0 to 6.18 g/100 g in Brown Rice; Albumin as 0.67 to 2.0 g/100 g, globulin as 0.652 to 2.0 g/100 g, prolamin as 0.20 to 2.3 g/100 g and glutelin as 1.684 to 5.258 g/100 g in White Rice. Results revealed a considerable variation also in gross grain protein contents among Brown and White rice of sixteen cultivars ranged from 5.087 to 9.644 g/100 g and 4.5 to 8.760 g/100 g respectively. Gross grain protein contents were higher in ASD-19, TKM (R) 12 and ADT 37 of Brown rice. Gross grain protein contents were higher in TKM (R) 12, ASD-19 and ADT-38 of White rice. The result on status of protein in Brown rice showed that ADT-40 had the highest Albumin content. ADT 37 exhibited the highest globulin content. The lowest prolamin content was found in TKM (R) 12, whereas the highest content of glutelin was found in ASD-19. The result of status of protein in White rice showed that TKM (R) 12 had the highest Albumin content. ADT 37 exhibited the highest globulin content. The lowest prolamin content was found in Anna (R) 4, whereas the highest content of glutelin was found in ASD-19. The highest Prolamin to Glutelin ratio was recorded in TKM (R) 12, CR 1009 /Ponmani and Anna (R) 4 for Brown rice. The overall results of this study revealed that ASD-19, TKM (R) 12 and CR 1009 /Ponmani were considered as Top three genotypes suitable for Tiruchirappalli district farmers based on consumer preferences.

A field experiment was conducted to evaluate the rice varieties suitable for organic farming. The experiment was carried out in the rabi season of 2013-14 at Tamil Nadu Agricultural University, Coimbatore to study the yield, quality and economics of different rice varieties. The experiment was laid out in a RBD replicated thrice. The treatments consisted of 12 rice varieties viz., Bhavani, White ponni, Mappillai samba, Kitchili samba, IR 20, CO 43, CO(R) 48, CO(R) 51, CB 05022, KDML 105, Red kavuni and Jeeraga samba. The culture CB 05022 produced significantly higher grain yield of 4877 kg ha-1 and registered a yield increase ranging from 32 to 82 per cent over the other varieties under evaluation. With regard to quality parameters, grains of the culture CB 05022 was medium slender based on the kernel length and L/B ratio. The highest net return of ` 40,015 ha-1 with B:C ratio of 2.28 was realised under the rice culture CB 05022 followed by Kitchili samba (net return: ` 32,423 ha-1; B:C ratio: 2.04) and Jeeraga samba (net return: ` 31,431 ha-1; B:C ratio: 2.01). It is inferred that varieties and cultures differ widely among themselves when grown under organic farming. In terms of grain yield, quality and economics, the culture CB 05022 performed better under the organic production system.

Seeking Behavior

Aim: This study aims to study the information seeking behavior of the respondents from various information sources and credibility of the information regarding TNAU released rice varieties. Study Design: Ex-post facto research design. Place and Duration of the Study: The present study was conducted in two blocks namely Melur and Madurai East blocks of Madurai district in Tamil Nadu. The study was conducted during July and August 2021. Methodology: 120 paddy growers from Melur and Madurai east blocks were randomly selected and interviewed using a pre-tested interview schedule to study the information seeking behavior of the farmers for the adoption Tamil Nadu Agricultural University (TNAU) released rice varieties. Results: Outcomes showed that cent percent of the respondents are getting information from their friends regarding newer varieties. 96.67 percent of the respondents seeks information from Agricultural Officers (AOs) whereas only 5.83 percent seek information from Agricultural Scientists. In recent days, farmers have started using various mass media sources like TV, Portals, websites, mobile apps and Kisan Call centers. The highest credibility of 93.33 percent score were obtained from Friends in personal localite source and 84.21 percent credibility was noted for the information from AOs in cosmopolite source. Also, cent percent credibility noted for Kisan call center amongst the respondents and less credibility observed for internet sources like websites and portals.It could be interpreted that the majority farmers was technologically illiterate to use e-sources like mobile apps, portals etc. as they had very less years of formal education. Conclusion: It can be concluded that the information sources can be designed based on farmers needs and preferences. And information gap should be reduced.
