Not AvailableRice is the major staple food of Andhra Pradesh and is widely grown in all regions of the State. There are significant changes in the macro policy environment and its implications for crop competitiveness since early 1990s. This paper examines the trends in production and competitiveness of rice in Andhra Pradesh in pre and post-WTO period and its implications in producer and consumer surplus and social cost benefits at State level. Rice registered an impressive growth in production in post-WTO period. Trade competitiveness of rice increased in post-WTO period as shown by DRC and NPC levels. EPC shows that rice production was fairly protected by the government policies even after post-WTO period. Overall, liberalization has positive impact on the welfare of the State. Distortion in domestic prices would result in a change in revenue to producers and consumers. Due to free trade ofrice, welfare gains were much larger than the respective welfare losses to the economy. The policy prescriptions from the study are (i) reduced cost of production by educating the farmers on improved crop management practices in rice fanning systems (ii) ensuring supply of quality inputs, replacement of low potential/ pest susceptible old varieties by new high yielding varieties with high yield potential (iii) encourage hybrid rice cultivation in suitable areas by conducting demonstrations and making seed available to the farmers (iv) providing farm implements and farm machinery for improving efficiency in farm operations and cost of cultivation and lastly (v) keep exports and imports free. Only use tariffs as an adjusting instrument.Not Availabl

Not AvailableMain focus of the present study is to analyse the current potential of various irrigation technologies adopted by farmers to mitigate crop risks inview of climate change. This also analyses important factors determining farmers' choice of specific technologies adopted by them, Findiangs of this study are based on the primary data clleted from 116 sample farmers of sholapur district of Maharastra. Current study revealed that the adopted irrication technologies have proved highly beneficial as farmers shifted from production of staple cereal food crops to demand-driven crops viz. vegetables and fruits. Adoption of drip or sprinkler irrigation system has significantly higher benefit-cost(B:C) ratio than convential irrigation metholdologies adopted usually by farmers. Fitting of Legit modelto the data revealed that the probability of adoption of irrigation technologies by farmers depends on benefit-cost(B:C) ratio, farm size, subsidy, access to credit and collective action undertabek by farmers, Salient outcome of the study is that overxploitation of groundwater shoudl be discouraged and water svaing techniques must be adopted to improve farm level efficiency.Not Availabl

Not AvailableRice, grown on a wide range of soils with varying soil pH levels boron (B) availability, uptake and mobilization could be limiting hence may lead to lower productivity and rice yields has been tested at 11 locations on low yielding rice genotypes from, Initial Evaluation Trials (IET) of AICRIP viz.IET 20979, IET 21003, IET 21007, IET 21014, IET 21025 and Rasi as check variety. Active boron supplemented as foliar spray at anthesis stage at 0.2, 0.4 and 0.8 ppm. Grains with 1.20 (High density), and 1.06 (normal density) specific gravity (sp. gr.) and unfilled grains were determined. The results showed that application of boron resulted in increase in grain number (25–45) and reduced the number of unfilled spikelets. At majority of the locations, application of 0.4 ppm boron had resulted in significant increase in grain yield (4–8%). Cultures, IET 20979, IET 21007, and IET 21014 showed a positive response with the 0.4 ppm application at the majority of locations.Not Availabl

Not AvailableWe selected 28 populations of Leucaena leucocephala from different geographical locations in the states of Andhra Pradesh, Tamil Nadu and Orissa of India on the basis of height and girth at breast height (GBH). We evaluated fiber length, optical density, wall thickness, vessel element length, vessel element diameter, specific gravity and lignin of these populations of L. leucocephala in different sites. Populations had significant variations for all growth, wood and paper parameters. Girth at breast height (GBH) and specific gravity were the most important parameters for heritability and genetic gain, respectively. The minimum heritability was reported for vessel element length and genetic gain for fiber length. The populations were grouped into six clusters, cluster II had maximum number of populations (14) and clusters IV and VI had one population each. GBH contributed maximum of 34.39 % towards total divergence followed by specific gravity (14.02%). An economic technique to produce quality seed by establishing seed orchards with genetically divergent parents was suggested. The hybridization among the populations selected from diverse clusters could produce greater heterosis needed for higher growth and suitable wood and paper manufacturing parameters.Not Availabl
