Adoption pattern and constraint analysis for achieving potential productivity of irrigated and rainfed rice ecosystems in Andhra Pradesh

The present study was carried out during 2010–11 at Department of Soil Science and Agricultural Chemistry, College of Agriculture, Rajendranagar, ANGRAU, Hyderabad to prioritize the constraints causing yield loss in both irrigated and rainfed rice. A study had conducted on 60 farmers in irrigated rice ecosystem and 30 farmers from rainfed ecosystem of Andhra Pradesh. It was found that the soil related constraints faced by farmers ranked from more to less serious and the constraints were related to low fertility of soil, inadequate organic matter, problem soils and multi nutrient deficiencies of the soils. Under crop management related constraints, it was found that adopting specific fertilizer application method, availability of improved variety, inadequate supply of water, infestation of weeds and higher pest incidence were the most serious constraints perceived by large percentage of farmers. In case of socio-economic constraints, the study found that the poor infrastructure, high cost of inputs, availability of credit, low price for the produce, inadequate inputs and lack of trainings were the most important constraints as perceived by large percentage of farmers. Other constraints as perceived by lower percentages of farmers were poor extension services, lack of information and lack of support from local authorities or government.
