A study  was conducted to find out the effective growth regulator and best time for spraying of growth regulator on flowering, corm and cormel production of gladiolous cv. Jacksonvilla Gold. Plants were sprayed with GA3 (50 and 100 ppm), NAA (100 and 200 ppm) and TIBA (50 and 100 ppm ) at 4, 6 and 8 weeks after planting. NAA 100 ppm followed by TIBA 100 ppm resulted in early flowering. Growth regulator sprays at 4 weeks and 6 weeks after planting recorded early flowering. Longest duration of flowering was recorded with NAA 200 ppm and 100 ppm spray at 6 and  8 weeks after planting. Maximum spike length and interfloret length were recorded with GA3 100 ppm spray at 6 weeks after planting. GA3 spray at 6 weeks after planting recorded maximum number of corms per plant. Maximum corm weight was recorded by NAA 200 ppm spray at 6 weeks after planting. TIBA 100 ppm sprays at 6 weeks after planting recorded maximum number and weight of cormels per plant.

Early flower initiation and consequently 50 per cent of flowering was recorded in December planting while maximum number of flowers per plant and flower diameter was recorded in October planting.  Similarly, early flower initiation, 50 per cent flowering, maximum number of flowers per plant as well as flower diameter were recorded in the plants spaced at 40 x 30 cm and applied with 100 kg N ha-1. October planting at a spacing of 40 x 30 cm with application of 100 kg N ha-1 was considered to be the best treatment for maximum flower production in marigold.

Application of H3PO4 ­  ( 0.5 %) followed by  KH2 PO4 (1.0 %) resulted in the highest percentage of new laterals flowered both in pruned and unpruned trees with and without paclobutrazol.  Similarly, the time taken from pruning to panicle initiation and panicle initiation to harvest was observed to be minimum in H3PO4 ( 0.5 %) followed by KH2 PO4 ( 1.0 %)  in pruned trees with paclobutrazol where as there were no significant differences among the treatments in unpruned trees.  Pruning significantly increased the number of laterals  while paclobutrazol helped in early cessation of vegetative growth and in combination with phosphorus – potassium chemicals resulted in minimum time taken for panicle initiation ultimately leading to early maturity.

Five different slow release fertilizer formulations were tested along with one recommended  fertilizer practice and one under native fertility conditions (control). The fertilizer formulations were adjusted to provide NPK @ 90-45-45 kg/ha. Panicle number (261-300), grain (3.80-5.01 t/ha) and straw (5.17-6.47 t/ha) yields were higher in farmers’ fields compared to research station (114-210, 2.35-3.79 t/ha, 2.75-4.83 t/ha of tillers, grain and straw yields respectively). At research station, chemical fertilizers out yielded all other treatments significantly while under farmers’ fields, slow release fertilizers also performed well and were on par with chemical fertilizers.  Among the slow release fertilizers, one mixture and one spike formulation at research station and two mixture formulations under farmers’ fields were comparatively better than other formulations. At all the three sites, the grain yield correlated significantly with yield components (r=0.607**-0.923**) and nutrients uptake (r= 0.777**-0.963**).
