India is a major producer of rice accounting for 42.50 million ha and production of 110 million MT accounting for 28.33 percent of Rarea and 22.13 percent of production. The major problems faced in cultivation of rice are low yield and lack of improved varieties resistant to pests and diseases. One of the major problems in rice cultivation is its susceptibility to Bacterial Leaf Blight (BLB). Hence, researchers made efforts to develop improved varieties to overcome the problem of BLB and developed resistant varieties of rice accordingly. However, the diffusion of these varieties slowed down in the recent years, resulting in stagnation of yields. Samba Mahsuri is one such variety which has got fine grain quality and is preferred among large section of consumers. However, this variety is susceptible to BLB. Keeping this in view, CSIR-Centre for Cellular and Molecular Biology (CCMB) in collaboration with Indian Institute of Rice Research (IIRR), developed Improved Samba Mahsuri which is resistant to BLB. Cultivation of ISM variety was popularized by National Seeds Corporation (NSC) and State Seed Corporations (SSCs). This variety is cultivated in many states across the country. As a result, over a period of time area under ISM increased substantially due to its resistance to BLB. Due to its resistance to BLB, use of pesticides reduced leading to lower cost of cultivation and hence became popular among the farming community in the country. However, in few of the states in India, there is a scope to increase area under ISM variety. In order to know the impact of ISM, CSIR-Centre for Cellular and Molecular Biology (CCMB) requested MANAGE to conduct a study to know the impact of ISM on socio-economic condition of the farmers. I appreciate the efforts of Dr. Amarender Reddy, Director (Monitoring & Evaluation) and Principal Investigator and his team in conducting the study. I hope, findings of the study will go a long way in popularizing cultivation of Samba Mahsuri and help the farming community in realising higher yields and thus leading to higher incomes. Hence, it is recommended that efforts should be made to popularize this variety across the States. (V. Usha Rani, IAS) Director General Acknowledgements he study on “Socio-Economic Impact Assessment of Improved Samba Mahsuri (ISM)”was carried out at the National Institute of Agricultural Extension Management T(MANAGE), Rajendranagar, Hyderabad, and was sponsored by the CSIR-Centre for Cellular and Molecular Biology (CCMB) Habsiguda, Hyderabad. In carrying out this study, we have benefited immensely from the guidance of various scholars and officials from different government departments. At the outset, we would like to thank Smt. V Usha Rani, IAS, Director General of our institute as well as Dr. Rakesh K Mishra, Director, CSIR-CCMB and Dr. Ramesh V Sonti, Chief Scientist, CSIR-CCMB, for their constant encouragement and support throughout the study. Special thanks to Dr. Muthuraman, Dr. Sundaram and Dr. Subha Rao from ICAR-IIRR. We also thank Dr. M. R. Vishnupriya and Dr. Hitendra Kumar Patel from CSIR - CCMB. We are grateful to Directors, Joint Directors and other officials from state departments of agriculture for their cooperation during the field survey as well as for their help in conducting Focus Group interactions and sharing their valuable suggestions. We thank Dr. Ratna Reddy, LNRMI, Hyderabad; Dr. Padma Raju, ex Vice Chancellor, PJTSAU, Rajendranagar; Dr. C.P. Chandrashekar, former Dean, PJTSAU, for their guidance and active involvement. We thank our colleagues at MANAGE for their constant support and encouragement in carrying out the study. We are also thankful to the field supervisors and surveyors for carrying out the field surveys and Focus Group interactions in different states and districts selected for the study across India. The study would not have reached this stage without the cooperation of cluster group leaders, who provided all the data required for the study without any hesitation and expectations. We thank each one of them for their invaluable support. Principal Investigator CONTENTS Executive Summary ..... xv Chapter 1 - Introduction 1.1. Rice Production Scenario ..... 1 1.2.
