    (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.

    Influence of Growth Promoting Substances and PGR’s on Flowering, Fruiting, Yield and Quality of Acid Lime (Citrus aurantifolia swingle) cv.Kagzi
    (JNKVV, 2013) Patel, Neha; Pandey, S.K.
    Abstract The present study entitled “Influence of growth promoting substances and PGR’s on flowering, fruiting, yield and quality of acid lime cv. Kagzi (Citrus aurantifolia Swingle)” was carried out of fruit Research Station, Imalia, JNKVV, Jabalpur during 2011-12 and 2012-13. The plants selected for trail were of similar age and vigour those received identical cultural treatments. The plant growth regulators viz., NAA (10, 20 and 30 ppm), 2,4-D (10, 15 and 20 ppm), GA3 (25, 50, and 100 ppm), growth promoting substances were urea (1, 2 and 3%) and ZnSO4 (0.4 and 0.5%). Equeous solution of above these chemicals were sprayed at 50% flowering and pea stage of fruit set. A water sprayed control was added and this made 21 treatments. The experiments was set up in a randomized block design with three replication. One plant was taken for each treatment in each replication. Percentage of male and perfect flowers were find out on the basis of counts per shoot at full bloom stage. Fruit set and retention percentage at various stages were recorded and the percentage of fruit drop was determined on the basis of initial number of fruit set and number of fruits retained after 30, 60, 90, 120 and 150 days after fruit set. The data tabulated for the year 2011-12 and 2012-13 separately and pooled of the two years. The data analyse as per appropriate statistical method. All the treatments at various concentrations significantly reduced fruit drop percentage. Minimum (5.60%) pin head size drop was noted with 20 ppm NAA, which is very close to urea 2 percent (6.13%) and maximum (20.96%) was recorded under control. Application of NAA at 20 ppm (11.71%) concentration significantly reduces the pea size fruit drop which was minimum (11.56) followed by urea 2% (18.80), while it was maximum in control (35.60%), Whereas, pre harvest fruit drop was reduced significantly by all the treatments over control. The minimum (8.36%) pre harvest drop was obtained with NAA 20 ppm, followed by urea 2 % (10.06%), while maximum (21.52%) fruit drop was noticed under control. The application of growth promoting substances and PGR’s increased the size of fruits with respect to length and diameter. Maximum length (2.28, 2.92, 3.71 and 4.97 cm) and diameter (1 .87, 2.17, 3.19 and 4.33 cm) of fruit after 60, 90, 120 days of fruit set and at harvest respectively were due to GA3 50 ppm + ZnSO4 (0.4%). On the other hand minimum fruit length and diameter of fruits at various stages of fruit growth and at harvest estimated under control. The weight of fruits were significantly increased with the spray of GA3 50 ppm (46.79 g) and NAA 20 ppm (45.78 9), While minimum (29.40 g) weight per fruit at harvest was noted under control. It was observed during the investigation that application of urea, NAA, 2,4-D GA3 and ZnSo4 at full bloom and pea stage of fruit set, significantly increased fruit retention percentage. Maximum fruit retention and minimum fruit drop percentage at different stages was obtained with the application of NAA 20 ppm followed by urea 2 percent and 2, 4-D 10 ppm. The fruit length and diameter was increase by this application of GA3 50 ppm + ZnSO4 (0.4%) and noted maximum under this treatments. Similarly, T.S.S., acidity, and ascorbic acid content improved by the spray of GA3 50 ppm + ZnSO4 (0.4%). The maximum values was recorded under GA3 50 ppm + ZnSO4 (0.4%). Yield of fruits was also increased significantly with the application of NAA 20 ppm followed by urea 2 percent.
