Effect of pre-harvest treatments with chemicals on yield,and storage of onion (Allium cepa L.) The experiment was laid out in Randomized Block Design with three replications along with ten treatments. The pre-harvest spray comprises of Streptocycline 200 Ppm (1.2 g/lit), Copper oxychloride 0.25 % (2.5 g/lit), Streptocycline 200 Ppm + COC 0.25 % (1.2 + 2.5 g/lit), Cycocel 500 Ppm (1 ml/lit), Cycocel 1000 Ppm (2 ml/lit), Carbendazim 1000 Ppm (1 g/lit), Carbendazim 2000 Ppm (2 g/lit), Mancozeb 0.25 % (2.5 g/lit), Azoxystrobin 1000 Ppm (2 ml/lit) and control (farmer practice). Pre harvest spray was given at just start of neck fall before harvesting. The observations on equatorial diameter (cm), polar diameter (cm), average weight of bulb (g), % of ‘A’ grade bulbs, % of ‘B’ grade bulbs, % of ‘C’ grade bulbs, % of doubles, % of premature bolters, total bulb yield (t/ha) recorded at the time of harvesting of bulbs and storage losses including, rotting, sprouting, plw, and total losses were recorded during storage at 30, 60, 90, 120, 150 and 180 days after storage
