“…About 70% of our farmers are cultivating paddy and the production is about 118.87 million metric tons and productivity being 2722 kg/ha. The total area under food grains and other important crops in Telangana is 57.72 lakh hectares with rice occupying an area of 23.4 lakh hectares in 2019-20 as against only 14.2 lakh hectares in 2014-15 showing an increasing trend (Pathak et al, 2019). The average productivity of the state during 2014-15 was about 3.10 t/ha which has been estimated to increase by about 0.50 DOI No.…”

This study was conducted to investigate the effect of insecticides with different mode of actions and differenttoxicity levels against coccinellids and spiders in rice ecosystem at Regional Agricultural Research Station,Warangal during rabi, 2020-21 with the test cultivar Telangana Sona (RNR-15048). The selected granularand foliar insecticides viz., flubendiamide 0.7G, flubendiamide 20 WDG, cartap hydrochloride 4G, cartaphydrochloride 50 SP, chlorantraniliprole 0.4G, chlorantraniliprole 18.5 SC, fipronil 0.3G, fipronil 5 SC andcarbofuran 3G (check insecticide) were evaluated for their safety against the populations of Coccinellids and spiders in rice ecosystem. The insecticides were applied twice, i.e, granular formulations were appliedeither in nursery or 25 DATor both while spray formulations were used at 60 DAT (at panicle initiation tobooting stage). Out of 14 treatments, maximum population of beneficials (coccinellids and spiders) wereregistered in untreated control (T14) followed by carbofuran (T13) with 38.83% reduction, fipronil (T10, T11,T12) and chlorantraniliprole (T7, T8 and T9) ranging from 40.80 to 63.22% reduction whereas Flubendiamide (T1, T2 and T3) and cartap hydrochloride (T4, T5 and T6) were found to have greater impact on beneficialfauna (58.78 to 77.78% reduction over control). From the study it was evident that carbofuran, fipronil andchlorantraniliprole were found relatively safer to beneficial populations in rice ecosystem.

“…Economic impacts of new technologies deliver helpful information to justify investment efforts in research and development to generate new technologies. Pathak et al (2018) and Pathak et al (2019) has estimated the area, production and return with rice varieties of NRRI, Cuttack in the country based on the amount of quality seeds provided to the farmers through various ways. Considering the importance of vegetable varieties developed by ICAR-Indian Institute of Vegetable Research, Varanasi, the present study was taken up with the objectives to estimate the area covered by the ICAR-IIVR varieties and assess the production and economic impact due to the spread of ICAR-IIVR varieties in the country.…”

The ICAR-Indian Institute of Vegetable Research, Varanasi has released a number of varieties and hybrids that have been widely adopted and cultivated by large number of farmers throughout the country. Therefore, the present study was taken up with the objectives to estimate the area covered by the Institute varieties and assess the production and economic impact due to the adoption and spread of ICAR-IIVR varieties in the country. The area covered by ICAR- IIVR varieties in the country during 2021-22 was estimated based on the number of quality seeds provided to the farmers and different government and private agencies through various channels. The average wholesale prices of different vegetable crops was collected and computed from Agmarknet. The analysis showed that ICAR- IIVR varieties has covered about 133133 ha in the country during the year 2021-22 including 23 vegetable crops and 62 varieties. The Institute variety has spread in 161 districts in 27 states and 3 UTs in the Country. The estimated incremental gain in production due to the adoption of ICAR- IIVR vegetable varieties was 112.67 thousand tons and the incremental gain in income with ICAR- IIVR varieties was estimated to Rs. 239.41 Crores during the year 2021-22. Tomato crop has the highest contribution in incremental gain in income among ICAR- IIVR varieties followed by chili, brinjal, bottle gourd and okra. Over the years, seed demand and sale of ICAR- IIVR varieties have been increasing indicating the growing popularity of ICAR- IIVR varieties among the farmers in the country.

“…However, it is facing unprecedented challenges of environmental degradation and climate change in recent years [6][7][8]. Low and uncertain income, degraded natural resource base, growing labour and energy shortages and threats of climate change are making Indian agriculture highly vulnerable and unsustainable [9][10][11][12].…”

Rice (Oryza sativa L) being one of the imperative food crops of the word contributes immensely to the food and nutritional security of India. The cultivation of rice is changed over the decades from a simple cultivation practices to the advanced cultivation to increase yield. Increased in rice yields especially after 1960s is mainly due to the introduction of high yielding semi-dwarf varieties which requires more inputs like chemical fertilizers, water and other resources. As a result, India achieved self sufficiency in rice and currently producing more than 115 MT of rice to meet country’s demand. Now India is exporting rice to other nations and earning foreign returns. With the change in rice cultivation practices, problems also aroused side by side. A number of biotic and abiotic stresses emerged as major constraints for rice cultivation in diverse agro-climatic conditions and growing ecologies. Diseases are the major biotic constraints to rice which can reduce the yields by 20–100% based on severity. Major diseases like blast, brown spot, bacterial blight, sheath blight and tungro still causing more damage and new minor diseases like bakanae, false smut, grain discoloration, early seedling blight, narrow brown spot, sheath rot have emerged as major problems. The losses due to these diseases may 1–100% based on the growing conditions, varietal susceptibility etc.., At present no significant source of resistance available for any of the above emerging diseases. But looking into the severity of these diseases, it is very important to address them by following integrated management practices like cultural, mechanical, biological and finally chemical control. But more emphasis has to be given to screen gerrmplasm against these diseases and identify stable source of resistance. Finally utilizing these sources in resistance breeding program by employing molecular breeding tools like marker assisted selection (MAS), marker assisted back cross breeding (MABB), gene pyramiding and transgenic tools. The present chapter discusses the importance of these emerging minor diseases of rice, the losses and possible management measures including resistance breeding.
