The present investigation was carried out at Horticulture Research Station, Jambavadi Farm, Junagadh Agricultural University, Junagadh (Gujarat) during October 2014 to March 2015. The experiment was laid out in Factorial Randomized Block Design. The treatments comprised of two factors (1) nitrogen with four level viz., 150 kg N ha-1(N1), 200 kg N ha-1(N2), 250 kg N ha-1(N3), 300 kg N ha-1(N4) and three levels of phosphorus i.e. 100 kg P2O5 ha-1(P1), 150 kg P2O5 ha-1(P2), 200 kg P2O5 ha-1(P3) with three replications. Both the highest levels of N and P significantly improved growth parameters i.e. plant height (51.56 cm), plant spread (328.67 cm2), secondary branches per plant (17.67), fresh weight (137.22 g) and dry weight (69.78 g) in treatment N4 (300 kg N ha-1) whereas, in case of phosphorus the plant height (47.08 cm), plant spread (316.00 cm2), number of branches per plant (16.92), fresh weight (132.00 g) and dry weight (72 g) was noted in treatment P3(200 kg P2O5 kg ha-1). Maximum flowering span (79.11 days), number of flowers per plant (24.78) and yield of flowers (22.67 t ha-1) were registered in 300 kg N ha-1 treatment. Similarly, maximum flowering span (71.58 days), number of flowers per plant (23.58) and yield of flowers (22.08 t ha-1) were registered in P3 (200 kg P ha-1). Thus, cultivation of China aster in medium black soil, the fertilizer application at the rate of 300 kg N ha-1 in two splits (first half as basal application and remaining half at 30 days after transplanting) and 200 kg P2O5 ha-1 as basal dose has been found the best.Keywords

The present experiment was conducted on effect of micronutrients (Fe and Zn) on growth, flowering, flower yield and quality of chrysanthemum(Chrysanthemum morifolium Ramat.) cv. IIHR – 6”. Growth was influenced by different levels of ferrous sulphate. The maximum plant height at 60 DAT (56.11 cm) and 90 DAT (72.33 cm), plant spread in N-S (30.67 cm) and E-W (22.67 cm) direction at flower bud initiation stage and in N-S (38.78 cm) and E-W (31.56 cm) direction at full bloom stage, number of primary branches (4.19) and secondary branches (24.89) at full bloom stage, leaf area (37.11 cm2), number of suckers per plant (20.33), fresh weight (306.67 g) and dry weight (35.44 g) of plant were obtained at FeSO4 @ 0.8 per cent (F4). In case of different levels of ZnSO4, the maximum plant height at 60 DAT (53.67 cm) and 90 DAT (70.33 cm), plant spread in N-S (29.75 cm) and E-W (21.83 cm) direction at flower bud initiation stage and in N-S (37.58 cm) and E-W (30.75 cm) direction at full bloom stage, number of primary branches (4.13) and secondary branches (23.00) at full bloom stage, leaf area (35.33 cm2), number of suckers per plant (18.33), fresh weight (297.50 g) and dry weight (33.00 g) of plant were obtained at ZnSO4 @ 0.5 per cent (Z3).

The present study was carried out at Department of Horticulture, Junagadh Agricultural University, Junagadh under south Saurashtra agroclimatic conditions during year 2012-13 and 2013-14. The treatments comprised of three locations viz., Junagadh (L1), Talala (L2) and Dhari (L3) and three commercially important mango varieties viz., Kesar (V1), Alphonso (V2) and Rajapuri (V3). The experiment was laid out in Randomized Block Design with Factorial concept (FRBD) and replicated four times. Significantly minimum days for bud differentiation (166.46 days with 1402.94 GDD) were observed at Talala location. Early flower initiation (73.04 days with 420.36 GDD) and short flowering span (60.42 days with 444.69 GDD) was observed at Talala location. Among varieties, early flower initiation (75.83 days and 381.04 GDD) and compact flowering span (60.63 days with 382.84 GDD) was observed in Kesar. Minimum days for fruit set (24.33 with 131.61 GDD), pea stage (20.63 with 173.10 GDD), marble stage (42.96 days and 446.48 GDD), egg stage (69.17 days and 809.13 GDD) and maturity (93.75 days with 1272.06 GDD) were required at Talala, while early fruit set (24.00 with 100.63 GDD), pea stage (20.83 with 144.47 GDD), marble stage (43.67 days and 361.66 GDD), egg stage (70.54 days and 694.79 GDD) and maturity (95.88 days and 1062.71 GDD) was noted in Kesar. The highest fruit set at pea (13.84%), marble (1.57%), egg stage (0.31%) and fruit retention (1.39%) were recorded at Talala. Among varieties, maximum fruit set at pea stage (13.84%) was recorded in Alphonso; on the contrary, it was maximum at marble (1.60%), egg stage (0.32%) and fruit retention (1.32%) in Kesar. Maximum numbers of fruits per tree were recorded at Talala location (335.21) and Alphonso variety (344.33).
