Not AvailableTobacco (Nicotiana tabacum L.) is an industrial plant because of its cured leaves which are used in cigarette, bidi, and cigar making. Due to the economic significance of cured leaves, the correlated response of cured leaves with other traits is of vital importance in tobacco breeding programmes. In the present research, correlation and path analysis is used to determine the inter relationship among cured leaf yield and other yield attributing traits .A field experiment was undertaken at Regional Agriculture Research Station, Nandyal, Kurnool Dt. Andhra Pradesh during 2017-18 in vertisols under rainfed condition to study twenty five genotypes of tobacco (Nicotiana tabacum L.) for correlations and path analysis. The estimates of correlation coefficient revealed that cured leaf yield was positively correlated at both genotypic and phenotypic levels with days to flowering (rg=0.782 * * , rp=0.502 * * ), number of leaves per plant (rg=0.854 * * , rp=0.874 * * ), plant height (rg=0.704 * * , rp=0.777 * * ), days to maturity (rg=0.575 * * , rp=0.431 * * ), leaf length (rg=0.670 * * ,rp=0.811 * * ) and leaf width (rg=0.883 * * ,rp=0.646 * * ), while it was negatively correlated with leaf thickness (rg= -0.623 * * ,rp= 0.781 * * ), nicotine (rg= -0.019 ,rp= -0.012) and reducing sugar content (rg= -0.343 * * ,rp= -425 * * ). Path analysis based on genotypic correlation showed that number of leaves per plant (0.846 * * ), plant height (0.781 * * ) and leaf length (0.865 * * ) are important characters that shows considerable direct effect on cured leaf yield and these characters are to be considered for improving the cured leaf yield, in bidi tobaccoNot Availabl

Not AvailableField experiment was conducted in tobacco based intercropping system at ICAR-CTRI RS, Jeelugumilli, Andhra Pradesh during Rabi season 2005-06 and 2006-2007 in Alfisols under irrigated upland ecosystem The results revealed that tobacco green leaf yield with the intercrops tested was significantly higher than sole tobacco except with radish. Total productivity of tobacco with different intercrops was rather improved as compared to sole tobacco. Garlic and coriander intercrops had complementary effect on base crop tobacco and the cured leaf yield of tobacco with garlic and coriander was higher by 217 (9.36) and 162 kg/ha (6.99%) respectively, as compared to that of sole tobacco (2318 kg/ha). Though there were significant differences in tobacco lamina quality characters due to different intercrops all the values were within the acceptable range. The intercropping system tobacco + amaranthus recorded maximum net returns of Rs 1,26,788/ha and benefit: cost ratio of 1.48 and there was 51.94% percent increase of net returns over sole tobacco. The other remunerative intercropping systems were tobacco + garlic followed by tobacco + fenugreek and tobacco + radish with a net returns of Rs 1,25,658, Rs 1,16,583 and Rs 1,14,700 and benefit: cost ratio of 1.46, 1.43 and 1.43, respectively. All the tobacco based intercropping systems showed net returns of >Rs 1,03,918 and benefit: cost ratio of >1.39 while sole tobacco recorded lower values of net returns (Rs 83,448) and B: C ratio (1.36). It can be concluded that component crops viz., amaranthus, spinach, fenugreek, coriander, carrot, onion, garlic and radish can be grown successfully without much competition to tobacco in between two paired rows of tobacco. Thus, in the long run the farmers in irrigated Alfisols under Northern Light Soils in East and West Godavari (dt) of AP and Khammam (dt) of Telangana may choose a system that gives maximum net returns as per the prevailing market demand taking into consideration the incidence of insect pests and diseases as well as soil health.Not Availabl

Report of AICRP TOBACCO WORKSHOP in 2018-2019In India different tobacco types viz., Flue Cured Virginia (FCV), Bidi, Natu, Chewing and Rustica are grown under diverse agro-climatic conditions. To cater the location specific needs of different tobacco types the All India Coordinated Project on Tobacco was established by Indian Council of Agricultural Research in the Fourth Five Year Plan during 1970-71 with the headquarters of the Coordinating unit at Anand (Gujarat). The headquarters was subsequently shifted to CTRI, Rajahmundry, A.P. on 16-08-1998. Further, the AICRP on Tobacco was renamed as All India Network Research Project on Tobacco and kept under the administrative control of the Director, CTRI, Rajahmundry. A total of number of 14 centres (3 Main centres, 7 sub-centres and 4 voluntary centres) are functioning at present.ICA
