    Effect of FYM and gypsum on onion (Allium cepa L.) production under sodic water irrigation
    (CCSHAU, 2014) Amit Kumar; Yadav, A.C.
    The experiment entitled Effect of FYM and gypsum on onion (Allium cepa L.) production under sodic water irrigation was conducted at Research Farm, Department of vegetable science, CCS Haryana Agricultural University, Hisar during 2013 in rabi season to find out the effect of FYM and gypsum on growth, bulb yield and quality of onion under sodic water irrigation as well as economics of different treatments. The cultivar used for the investigation was Hisar-2. The treatments comprising three levels of FYM (0, 10 and 20 t/ha) and gypsum (0, 50 and 100% neutralization of RSC) and its combinations were laid out in a factorial randomized block design with three replications keeping a net plot size of 3.0 x 3.0 m. The data were recorded on various parameters, which were influenced by different levels of FYM and gypsum. The minimum values for seedling mortality per cent, soil pH, ESP, bulb dry matter and TSS, while, maximum values for growth and yield parameters viz. plant height, number of leaves per plant, plant survival at harvest, bulb length, bulb diameter, bulb yield, per cent marketable bulbs, size of bulbs and quality of bulbs were recorded with combination of FYM at 20 t/ha and 100% neutralization of RSC by gypsum. Highest net return and benefit:cost ratio was recorded in combination of FYM at 20 t/ha and 100% neutralization of RSC by gypsum. The results suggest that the combination of FYM at 20 t/ha and 100% neutralization of RSC by gypsum has shown the best economical treatment in onion for higher yield with quality bulb production at commercial scale under semi-arid condition of Hisar (Haryana).
