Abstract:

A field experiment was conducted at Agricultural Research Station, Kota during the rabi seasons of 2017-18, 2018-19 and 2019-20 to evaluate effective dose of hydrogel and salicylic acid for increasing the productivity, quality and water-use efficiency of Indian mustard in restricted irrigation condition of S-E Rajasthan. The experiment consisting of 12 treatment combinations,viz.T1:control, T2:hydrogel 2.5 kg/ha,T3:hydrogel 5 kg/ha,T4: salicylic acid (SA) 100 ppm at flowering (fl) and siliqua formation (sf),T5:SA 200 ppm at fl and sf,T6:hydrogel 2.5 kg/ha + SA 100 ppm at fl and sf, T7:hydrogel 2.5 kg/ha + SA 200 ppm at fl and sf, T8:hydrogel 5 kg/ha + SA 100 ppm at fl and sf, T9: hydrogel 5 kg/ha + SA 200 ppm at fl and sf, T10:Two irrigation at pre-flowering and siliqua development, T11: hydrogel 2.5 kg/ha + SA 100 ppm at fl and T12:hydrogel 2.5 kg/ha + SA 200 ppm at fl were laid out in randomized block design with three replications. Among treatment combinations, application of hydrogel 5 kg/ha with two spray of salicylic acid 200 ppm at flowering and siliqua formation stage significantly  increased plant height (222.40 cm), dry matter/plant (62.20 g), branches/plant ( 16.33), siliquae /plant (236.67), seeds/ siliqua (16.23), 1000-seed weight (5.47 g), seed yield (2651.89 kg/ha), oil content (38.95 %) and oil yield (1032.91 kg/ha), protein content (21.07 %), gross return (1,13,404/ha), net return ( 82,818/ha) and soil moisture retention (13.70 %) over T1, T4, T5 and T2 and at par with rest of treatments. While, the highest water-use efficiency (12.83 kg /ha-mm) was recorded under the same treatment but it was significantly superior over T1, T2, T3, T4, T5 and T10 and on par with rest of treatments. Whereas significantly higher B: C ratio (3.46) recorded in irrigation treatment over all the other treatments. Furthermore significantly highest improvement in growth, yield attributes and economics was recorded under irrigation treatment applied at pre-flowering and siliqua formation stage over T1 and alone application of hydrogel and SA. Thus, the result showed that application of hydrogel  either 2.5 or 5 kg/ha with two spray of SA 200 ppm at flowering and siliqua formation was found beneficial for obtaining high seed yield, WUE as well as net returns.
