    Effect of salicylic acid and azospirillium on yield and quality characters of onion (Allium cepa L.)
    (JNKVV, 2016) Prajapati, Sunil; Jain, P.K.
    Abstract The present study entitled “Effect of Salicylic acid and Azospirillum on yield and quality characters of onion (Allium cepa L.)” was carried out at Horticulture Complex, Maharajpur, Department of Horticulture, Jawaharlal Nehru Krishi Vishwa Vidyalaya, Jabalpur (Madhya Pradesh) during the Rabi season of 2013-14 and 2014-15.The experiment was laid out in Randomized Block Design (RBD) with three replications and each replication consisted of eighteen treatments with 18 treatments (1check) combinations of Salicylic acid (SA) and Azospirillum in onion cv. Agrifound Light Red to estimate the best responsive treatments on growth, yield and quality traits, all the treatments were randomized separately in each replication. Morpho-physiology parameters i.e., plant height (cm) at 30,60,90 and 120 DAT, length of leaves (cm) at 30,60,90 and 120 DAT, number of leaves plant-1 at 30,60,90 and 120 DAT, neck thickness of bulb (mm) at 30,60,90,120 DAT, dry weight of leaves (g) at 30,60,90 and 120 DAT. Post-harvest parameters i.e. average weight of bulb (g), bulb equatorial diameter (mm), bulb polar diameter (mm), % A, B,C Grade bulbs (on weight basis), double bulbs (%), bolters (%), storage loss in weight (%).yield attributes parameters i.e. bulb yield plot-1,total bulb yield (t/ha.), marketable yield (t/ha). chemical estimation i.e. total soluble solids (%), chlorophyll content index at 30,60 &90 DAT, shape of bulbs (flat/ oval/ round), bulb cross section (symmetrical/asymmetrical), disease pest incident percentage and economics (B: C ratio). The data tabulated for the year 2013-14 and 2014-15 separately and also pooled for the two years. The data analyzed as per appropriate statistical method. This present study concluded that all the growth parameters of onion plant under study noted that (T17) Salicylic acid (250 mg/lit.) at 30 DAS, 30,45,60 DAT and Azospirillum (5 kg/ha) at 60 DAT was performed superior over control such as highest plant height at 30, 60, 90,120 DAT (34.24 cm), (38.16 cm), (46.83 cm) and (48.72 cm), length of leaves at 30, 60, 90,120 DAT (32.37 cm), (37.54 cm), (42.74 cm) and (44.82 cm), number of leaf plant-1 at 30, 60, 90,120 DAT (7.85) (T14), (12.72), (17.79),(19.51) respectively, neck thickness at 30, 60, 90,120 DAT (11.90 mm),(16.27 mm)(T14), (13.67mm) and (13.04 mm) respectively, dry weight of leaf at 30, 60, 90,120 DAT (1.47g),(2.63g),(3.03 g), (3.99g) respectively. The bulb yield and quality traits also reported best responsive under (T17) Salicylic acid (250 mg/lit.) at 30 DAS, 30,45,60 DAT and Azospirillum (5 kg/ha) at 60 DAT as Chlorophyll content index at 30, 60, 90 DAT (30.82), (43.22) and (45.52) respectively, TSS (13.98), polar diameter (60.89 mm), double bulb(1.53%),bolters(0.69%),A,B&C grade bulb (37.32%),(65.73%) and (42.22%) respectively, bulb yield polt- 1(14.84kg), marketable bulb yield (27.41 t/ha.), total bulb yield (30.04t/ha), except higher average weight of bulb (81.68g) and equatorial diameter (62.04mm) recorded under (T11).Among the 18 treatments best responsive treatments as T17, T11, T16 and T5 showed round shaped bulb and symmetrical cross section. The study of physiology weight loss recorded minimum in T11 (1.55%) at day 10, (T5) SA (250 mg/Lit.) at 30 DAS, 30, 60 DAT (2.15%) and (3.14%) at 20, 30 days respectively. Purple blotch Incidence percentage during crop growth was significantly influenced by the application of Salicylic acid and Azospirillum, the minimum occurrence of purple blotch was recorded under treatment (T5) T1+ Azospirillum (5 kg /ha) at 30 DAT (0%),(0.95%),(1.80%),(2.40%) and stemphylium blight infested was recorded under treatment (T17) salicylic acid (250 mg/lit.) at 30 DAS, 30,45,60 DAT and Azospirillum (5 kg/ha) at 60 DAT (0.66%), (3.37%), (4.44%), (2.40%) in the months of January, February, March and April respectively. Thrips incident percentage was also recorded under treatment (T17) (0.60%), (4.48%), (10.78%) and (8.15%) in the month of January, Febuary, March, April respectively. Economic analysis of Salicylic acid and Azospirillum treated plants response well in treatment (T16) T5+ Azospirillum (5 kg /ha) at 60 DAT fetched highest gross monitory return (Rs.455285/ha), net return (Rs. 384375/ha) and benefit cost ratio 5.85 fallowed by (T17) SA (250 mg/Lit.) at 30 DAS, 30 DAT, 45 DAT, 60 DAT+ Azospirillum (5 kg /ha) at 60 DAT which was reported gross monitory return (Rs.435285/ha), net return (Rs. 369400/ha) and benefit cost ratio 5.60, (T11) SA (250 mg/Lit.) at 30 DAS, 30 DAT, 45 DAT, 60 DAT+ AZSP (5 kg /ha) at 30 DAT estimated gross return (Rs.435060/ha), net return (Rs.369175/ha) and benefit cost ratio 5.60.
