| dc.description.abstract | The investigations on integrated nutrient management and scheduling of drip irrigation in onion were carried out at Regional Agricultural Research Station, Bijapur, Karnataka on medium deep black soil during 2004-05 rabi and 2005 summer. In integrated nutrient management (INM) experiment, there were 20 treatments involving three inorganic fertilizer levels and six organic manure levels with two controls (RPP and absolute control). The experiment on scheduling of drip irrigation included three irrigation intervals and three irrigation levels with flood irrigation as control. The experiments were laid out in a split-plot design with three replications each. The results of INM experiment indicated that, higher levels of inorganics i.e. 162:32:148 kg NPK ha-1 (41.55 t ha-1) and 81:16:74 kg NPK ha-1 (41.09 t ha-1) as well as higher levels of organic manures i.e. FYM at 30 t (40.56 t/ha), vermicompost at 6 t (41.65 t/ha) and poultry manure at 3 t (40.88 t/ha) per ha recorded higher bulb yield individually. The similar trend was observed in growth and yield parameters along with net returns and B:C ratio. The physiological loss in weight, sprout and rot per cent were significantly lower with no inorganics and higher levels of organics at different storage periods. In the experiment on scheduling of drip irrigation, one and two days intervals of irrigation with 100 per cent PE recorded significantly higher growth, yield parameters, bulb yield, net returns and B:C ratio over other interactions. Compared to flood irrigation, one or two days intervals with 100 per cent PE and two days interval with 80 per cent PE were significantly superior. All the irrigation intervals, levels and their combinations recorded significantly higher WUE compared to flood irrigation. | en_US |
