S.The present studies entitled “Effect of plant growth regulators and fertilizer on flowering in spider lily (Hymenocallis littoralis L.)” was carried out at Department of Horticulture, College of Agriculture, Dapoli. Two experiments were carried out namely as effect of plant growth regulators on spider lily and effect of fertilizer on spider lily. The experiment, effect of plant growth regulators on spider lily was laid out in RBD with ten treatments and three replications. Treatments consisted as GA3 150 ppm, GA3 200 ppm, GA3 250 ppm, NAA 50 ppm, NAA 100 ppm, NAA 150 ppm, CCC 750 ppm, CCC 1000 ppm, CCC 1250 ppm and control. Application of plant growth regulators significantly influenced the various plant growth parameters and flowering parameters. Maximum plant height (80.17 cm), maximum number of leaves per plant (122.47), highest leaf area index (0.396 m2) and maximum bundles yield per ha (49054.91) at 270 DAT, was recorded with treatment GA3 at 250 ppm. Less number of days required for emergence of flower (33.00) and for 50% flowering (38.10) recorded in treatment GA3 @ 250 ppm while, maximum length of flower (21.77 cm), maximum diameter of flower (4.35 cm), maximum number of flower buds per plant (71.06), maximum yield of flower buds per plot (3.08 Kg) and maximum yield of flower buds per ha (4.28 t) at 270 DAT, was recorded with treatment GA3 at 250 ppm. Maximum bulb yield per plant (9.87), per plot (13.02 kg) and per ha (28.94 t) was recorded in treatment GA3 at 250 ppm. These parameters were significantly increased with increase in concentration of GA3 and decreased with increase in concentration of NAA and CCC. The experiment, effect of fertilizer on spider lily was laid out in FRBD with 20 treatment combination and four replications. Treatments consisted of five levels of nitrogen (0, 300, 350, 400 and 450 Kg/ha), two levels of phosphorous (0 and 200 kg/ ha) and two levels of potassium (0 and 150 kg/ha) on spider lily. All the growth parameters significantly influenced by different levels of nitrogen. Maximum plant height (98.85 cm), maximum number of leaves (149.38) and (0.879 m2) at 270 DAT, was recorded with application of nitrogen at 450 kg ha-1. Also, less number of days required for emergence of flower and for 50 % flowering, maximum length of flower (20.64 cm), maximum diameter of flower (4.49 cm), maximum number of flowers (56.51), maximum flower yield per plot (1.41 Kg), maximum flower yield per ha (3.92 t), maximum number of bulbs (16.43), maximum bulb yield per plot (196.56 Kg) and maximum bulb yield per ha (46.65 t) at 270 DAT were recorded in T4. All growth parameters were significantly increasing with increase in level of nitrogen application. Less number of days required for emergence of flower (27.60) and for 50% flowering (40.30) was recorded in P1. The number of days required for emergence of flower and for 50% flowering was decreased with increase in level of phosphorous and it remained non-significant. Maximum number of flowers per plant (30.23), maximum flower yield per plot (0.76 Kg), maximum flower yield per ha (2.10 t) at 270 DAT were recorded in P1 200 Kg. Maximum number of bulbs (10.84), maximum bulb yield per plot (162.03 Kg) and maximum bulb yield per ha (41.32 t) was recorded in P1. Bulb yield per ha significantly increased with increase in level of phosphorous application. Application of potassium on spider lily does not significantly influenced the various growth, flower and yield parameters and remain non-significant. Interaction of nitrogen and phosphorous significantly influenced flower yield. Maximum number of flowers per plant (43.37), flower yield per plot (1.08 kg), flowers per ha. (3.01 t) at 270 DAT were recorded in N4 + P1 and K1. Remaining treatments interaction remains non-significant with all parameters. Interaction of nitrogen and phosphorous was significantly influences bulb yield. maximum bulb yield per plot (197.68 Kg), maximum bulb yield per ha (47.37 t) was recorded in N4 + P1 and K1. Remaining treatments interaction remains non-significant with all parameters.ThesisItem Open Access Effect of set planting on kharif onion bulb-production cv. baswant-780 and s-1.(Mahatma Phule Krishi Vidyapeeth, Rahuri, 2004) Yevale, H.

S.The present investigation entitled “Response of Banana cultivars to various doses of Nitrogen (Musa Paradisica L. and Musa accuminata L.)” was conducted at nursery No. 4, Department of Horticulture, College of Agriculture Dr. B. S. K. K. V. Dapoli, Dist. Ratnagiri during the year 2017-19. The experiment was conducted in split plot design with fifteen treatment combinations and three replications. The experiment was conducted as per the approved outline of research work from December 2017 to March 2019. Two factors were studied during the investigation viz., different varieties - V1 (Konkan Safed Velchi), V2 (Red Banana), V3 (Grand Naine), as main plot treatments and Nitrogen levels viz., F1 (200:100:100 NPK g/plant), F2 (100:100:100 NPK g/plant), F3 (300:100:100 NPK g/plant), F4 (400:100:100 NPK g/plant), F5 (500:100:100 NPK g/plant) as subplot treatments. The results of investigation revealed that, all the three varieties, nitrogen levels and their interactions recorded significant variation on different vegetative parameters, flowering parameters, fruiting parameters, yield and yield attributing characters. With regards to the interaction of varieties and nitrogen levels, at 270 DAP, vegetative parameters like plant height, girth, leaf area were found to be significant; while number of leaves, leaf area index were found to be non-significant. The highest height due to interaction effect of varieties and nitrogen was recorded in the treatment V2F3 (308.7cm). The highest girth due to interaction effect of varieties and nitrogen was recorded in the treatment V2F3 (68.9cm). The least number of days required for boot leaf stage due to interaction effect of varieties and nitrogen were recorded significantly in the treatment V3F1 (203.7 days). The least number of days required for commencement of flowering due to interaction effect of varieties and nitrogen were recorded non-significantly in the treatment V3F1 (202.2 days). The least number of days required for commencement of fruiting due to interaction effect of varieties and nitrogen were recorded significantly in the treatment V3F3 (194.2 days). The highest bunch weight was due to interaction effect of varieties and nitrogen which were recorded significant in the treatment V3F3 (22.5 kg). The lowest stalk weight was due to interaction effect of varieties and nitrogen recorded significant in the treatment V1F4 (0.69 kg). The highest length of bunch due to interaction effect of varieties and nitrogen recorded significant in the treatment V3F3 (98.7 cm). Maximum number of fingers due to interaction effect of varieties and nitrogen was recorded significantly in the treatment V3F3 (18.4). The least number of days required for maturity due to interaction effect of varieties and nitrogen were recorded significantly in the treatment V3F3 (94 days). The highest yield was due to interaction effect of varieties and nitrogen were recorded significantly in the treatment V3F3 (22.5 kg/plant). The highest yield due to interaction effect of varieties and nitrogen was recorded significantly in the treatment V3F3 (69.3 t/ha). Among all three varieties sensory score (8.5) i.e. liked very much was obtained in Konkan Safed Velchi. Thus present investigation entitled "Response of Banana cultivars to various doses of Nitrogen (Musa paradisica L. and Musa accuminata L.)” has helped to conclude for better vegetative growth, yield and yield attributing characters along with quality parameters. To get better growth Red Banana performed well and for yield Grand Naine performed the best. For obtaining maximum yield of Banana, Nitrogen dose F3 i.e. (300:100:100 g NPK/ plant) to Grand Naine performed best. For maintaining the quality of Banana shelf life was highest in Konkan Safed Velchi with RDF i.e. F1 (200:100:100NPK g /plant). Among all three varieties maximum sensory score (8.5) i.e. liked very much was obtained in Konkan Safed Velchi. Based on the present research findings it is found that Grand Naine with fertilizer dose F3 i.e. 300:100:100 g NPK/plant was superior for yield. But these results need further conformation for at least one or two seasons, as the present findings are based on single season crop.ThesisItem Open Access Studies on earhead molds of Jowar (Sorghum vulgare Pers.)(Mahatma Phule Krishi Vidyapeeth, Rahuri, 1977) Patil, R.
