The results revealed that the overall cost of cultivation as well as the economics of marigold flower production was significantly influenced by various Integrated nutrient management (INM) schedules. French marigold ‘Local’ plants supplied with 75% RDF + Spent mushroom compost (1 kg/m2) + Biofertilizers + 1% foliar spray of MKP (00:52:34) produced maximum yield of saleable flowers (25000 Kg/ha) followed by 75% RDF + Biofertilizers + 1% foliar spray of MKP (23000 Kg/ha) which was significantly superior over the 100% RDF recording 20000 Kg/ha flower yield. Both the above mentioned treatments also recorded maximum net returns of Rs.339171.60/ha. The highest benefit : cost (B: C) ratio o...

Gerbera is one of the most highly ranked flowers due to its beauty, wide variety of colours and ability to rehydrate after long transportation. Propagation through division is too slow and impractical. In vitro propagation is now commonly used to quickly increase cultivar selections for both cut and flowering potted plants. For commercialization of this crop and to meet the growing demands for planting material, tissue and organ culture techniques are being used as alternative methods for propagation. In this review, the scattered information on clonal multiplication of Gerbera through micro propagation worldwide are being tried to put together. This could eventually be helpful in drawing the attention of the researchers and scientists to work on it, besides would be benefitted by utilizing the knowledge reviewed in this paper.

Master. The results revealed that the overall cost of cultivation as well as the economics of carnation cut flower production was significantly influenced by the fertilizer application. Carnation cv. Master plants fertigated with 250 ppm N and K through urea and MOP in combination with 250 ppm NPK foliar spray through Sujala (19 : 19 : 19 NPK) once a week produced maximum saleable flowers (517.25 nos./m 2 ) for three flushes over the recommended practice (437.50 nos./m 2 ). The same treatment also recorded maximum returns of 3470.33/m 2 with highest B : C ratio of 2.27 for three flushes.

The treatments comprised of four planting dates, viz., 1st September (D1), 1st October (D2), 1st November (D3) and 1st December (D4) and three plant spacings, viz., 40×20 cm (S1), 40×40 cm (S2) and 40×60 cm (S3). The experiment was laid out in Factorial Randomized Block Design with twelve treatment combinations replicated thrice. Among different planting dates, maximum disease incidence (52.17%) was observed in 1 December planting, while minimum disease incidence (9.48%) was obtained in 1 September planting. As regards the effect of spacing, more disease incidence (29.75%) occurred at closer spacing of 40×20 cm as compared to the lesser disease incidence (23.06%) recorded with wider spacing of 40×60 cm. With regards to interaction effects, maximum disease incidence (60.50%) was observed in 1 December planting with closer sp...

Plants of chrysanthemum cultivars Purnima and Ajay were grown in open field condition with 17 different nutritional regimes during 2009 and 2010. The experiment was laid out in factorial randomized block design, replicated thrice. Findings revealed highest amount of available soil N (373.04 kg/ha), K (283.18 kg/ha) and organic carbon content (1.260 %) in the plots receiving 30 g/m 2 each of NPK + vermicompost (1 kg/m 2 ) + biofertilizers. Maximum available soil P (39.86 kg/ha) was recorded with the application of 22.5 g/m 2 each of NPK + vermicompost (1kg/m 2 ) + biofertilizers. No significant change was observed in soil pH and electrical conductivity due to different treatments. Azotobacter population (10.50 × 106 cfu/g ...

Experimental factors include nine foliar applications of growth regulators viz., Control (no application), two doses each of GA3, salicylic acid, benzyl adenine, cycocel, and two application times viz., (i) application at 25 DAT, (ii) application at 50 DAT. Results suggest that foliar spray of 250 ppm gibberellic acid enhanced growth, and improved seed yield and quality parameters of marigold. Among the times of application tested, it was observed that application at 25 days after transplanting (DAT) gave superior values for all the flower and seed parameters under study.

The treatments comprised of four planting dates, viz., 1st September (D1), 1st October (D2), 1st November (D3) and 1st December (D4) and three plant spacings, viz., 40×20 cm (S1), 40×40 cm (S2) and 40×60 cm (S3). The experiment was laid out in Factorial Randomized Block Design with twelve treatment combinations replicated thrice. Number of primary branches per plant (16.89), plant spread (48.33 cm), flower diameter (6.89 cm), number of flowers per plant (50.10), weight of flower per plant (466.35 g), flower yield per plot (20.97 kg) and flower yield per hectare (25903.31 kg) were found to be statistically higher in 1st October planting. Among various spacings, 40×20 cm recorded significantly maximum flower yield per hectare (26483.56 kg ha−1) than 40×40 cm and 40×60 cm spacing. Other growth parameters like number of primary branches per plant (13.43), plant spread (41.13 cm), and flower diameter (6.32 cm) was found to be significantly higher in 40×60 cm. However, duration of flowering (43.25 days) was found to be significantly higher in 40×40 cm spacing which, in turn, was statistically at par with 40×60 cm spacing. Further, the interaction effect of planting dates and spacing on plant height, plant spread, number of primary branches per plant, flower diameter, number of flowers per plant, weight of flower per plant and flower yield per hectare was found to be significant.
