Spiraling prices of onions in India undermine the sustainability of current economic growth process and raised the question of price integration among the spatially separated markets. Co-integration test has been used to identify whether onion markets in India share a common linear deterministic trend and the law of one price holds true in view of rising prices in the recent past. The study sourced the wholesale daily prices of major onion markets across the country from January 2010 to March 2011. Augmented Dickey Fuller test statistic has been used to check the presence of a unit root in the time series data. Empirical results indicated the presence of unit root and a strong spatial integration between major markets. The study also confirms the law of one price in Indian onions.

Field studies were conducted during the four rabi seasons (2011-12 to 2014-15) to investigate the impact of seed priming and micro irrigation on crop establishment, growth, productivity, and water productivity in wheat under different moisture regimes. Results indicated that sprouted seed (5830 kg ha-1) and primed seed (5766 kg ha-1) produced significantly higher grain yield in comparison to un-primed seeds (5416 kg ha-1). The germination was quick in the primed and sprouted seeds relative to non-primed seeds resulting in a better crop establishment and higher yield under optimum, sub-optimum and dry soil conditions. Irrigation method treatments viz., check basin, drip, sprinkler and drip + rainport showed that the grain yield was highest in the drip + rainport. Water productivity was highest in drip method of irrigation (1.61 kg m-3) followed by drip + rainport method (1.60 kg m-3) with a maximum mean productivity of 5539 kg ha-1. Around 600 m 3 ha-1 has been saved using seed priming thus reducing the cultivation cost by Rs. 382/ha. Among the micro irrigation techniques, water saved was highest in drip followed by sprinkler and drip + rainport. The study suggests for adoption of drip and seed priming to take advantage of yield enhancement as well as cost reduction through reduced utilisation of water.
