    IMPACT OF DIFFERENT HARDENING SUBSTRATE ON GROWTH AND SURVIVAL RATE OF IN VITRO RAISED PLANTLETS OF ORCHIDS (Dendrobium nobile)
    (Indira Gandhi Krishi Vishwavidyalaya, Raipur (C.G.), 2020) Khilari, Madhavi; Verma, L.S.; Tamrakar, S.K.; Kuruwanshi, V.B.; Saxena, R.R.
    The present research “Impact of Different Hardening Substrate on Growth and Survival Rate of In Vitro Raised Plantlets of Orchids (Dendrobium nobile).” was undertaken with a view to analyse the effect of different hardening media at Poly house of Commercial Tissue Laboratory, College of Agriculture, Indira Gandhi Krishi Viswavidyalaya, Raipur, Chhattisgarh during 2019-20. The experiment layout has been kept in Completely Randomized Design (CRD) in combination of 16 treatments replicated thrice. The results reveals that the highest value for parameters including height of plant, number of leaves plant-1, length of leaf, width of leaf, leaf area, leaf area index, survival % has been recorded in T8 (Chopped coconut husk + Brick + Charcoal + Cocopeat). The highest shoot girth has been observed in T2 (Bark + Brick + Charcoal + Cocopeat) and maximum number of root plant-1, length of root, root volume has been observed in T9 (Chopped coconut husk + Brick + Charcoal + Rice Husk). Better outcome were obtained by the treatment T8 as it contained coconut husk, brick pieces, charcoal and cocopeat. Where, coconut husk is ideally suited for enhancing the water holding ability of the substrate and nutrient content at initial phase, brick pieces help to provide good aeration and mechanical support to plants, charcoal has also been effective in aerating and retaining fertilizer when pouring fertilizer solution and it continuously transfer nutrients to developing plants on subsequent watering, cocopeat carries eight times of water of its weight it improves water holding capacity of media and also releases nutrients over long periods. While treatment T10 gives minimum outcomes in almost all parameters might be due to the reason that medium containing chopped paddy straw, brick and charcoal could not supply enough support and nutrients required for the growth and also get compact after decomposition of paddy straw. Therefore the substrate combination T8 (Chopped coconut husk + Brick + Charcoal + Cocopeat) may be recommended for hardening substrate of orchids.

    The present investigation entitled “Effect of Pinching on flower size and yield of Chrysanthemum Varieties” was conducted at Pt. K.L.S. College of Horticulture and Research Station, Pendri Farm, Rajnandgaon (C.G.) during Rabi season 2019-2020. The experiment comprised of four varieties (Yellow Gold, Lalima, Punjab Gold and Aparajita) and four level of pinching (No Pinching (control), Pinching at 30 days after transplanting, Pinching at 45 days after transplanting and Pinching at 30 and 45 days after transplanting) in chrysanthemum was carried out in Factorial Randomized Block Design with three replication having 16 treatment combinations. Regarding different varieties the experimental result revealed that height of plant (56.48 cm), plant spread (36.89 cm) and no. of branches plant-1 (30.22) was found maximum at variety Punjab Gold followed by Yellow Gold. Stem diameter (0.58 cm) was found maximum in Punjab Gold which was at par with Aparajita. Earliness in days taken to first bud initiation (58.04 days) and days to fully opened flower from bud emergence (17.83 days) was reported in variety Punjab Gold followed by Lalima. Variety Lalima is reported minimum days to first harvesting (77.93 days) followed by Punjab Gold. Yellow Gold variety was found superior over other three varieties in quality parameters i.e. flower diameter (5.80 cm), pedicel length (8.40 cm), weight of single flower (2.99 cm) and shelf life (4.42 cm). The maximum no. of flowers plant-1 (104.11) was registered in cv. Punjab Gold. Yellow Gold followed by Lalima was found better in terms of flower yield per plant (270.99 g) and flower yield ha-1 (211.70 q) among all other varieties. Among various pinching levels, for most of the growth, floral and quality and yield parameters i.e, plant spread (35.02 cm), no. of branches plant-1 (24.79) and no. of flowers per plant (107.27) flower yield plant-1 (211.57 g) and flower yield ha-1 (165.29 q) pinching at 30 and 45 DAT was observed superior over various pinching treatments. Stem diameter (0.51cm) was found maximum under pinching at 30 DAT. No pinching (control) treatment was found maximum in plant height (57.15 cm), flower diameter (5.42 cm), pedicel length (7.48 cm) and weight of single flower (2.44 g), shelf life of loose flower (3.97 days), early in days taken to first flower bud initiation (55.90 days), days to fully opened flower from bud emergence (15.87 days) and days to first harvesting (73.96 days) followed by pinching at 30 DAT. From all over sixteen treatment, Yellow Gold variety with pinching at 30 and 45 days after transplanting (1:2.96) followed by 45 days after transplanting in same variety.

    The present research entitled “Response of Fly Ash on Growth and Flower Yield of African Marigold (Tagetes erecta L.) Cv. Pusa Basanti Gainda under Chhattisgarh Plain Conditions” was undertaken with a view to analyse the impact of fly ash on vegetative and floral characters of African marigold in order to determine its suitability as a fertilizer. The field study was performed at the Horticultural Research cum Instructional Farm, IGKV, Raipur (C.G.) during 2019-20 (Rabi season). The experimental layout has been kept in Randomized Block Design (RBD) in combination of 16 treatments replicated thrice constituting RDF, FYM, fly ash and a control treatment. The application of different treatments with fly ash combinations increased African marigold flower yield as compared to control. Among the treatments T14 (Fly ash 40 t/ha + 75% RDF + FYM 5 t/ha) gave highest yield (156.8 q/ha) and highest net income (1,28,073.57 Rs./ha) than all other treatments including control. Treatment T13 (Fly ash 20 t/ha + FYM 5 t/ha + 75% RDF) showed significant effect on vase life (10.3 days) and has been found to be superior over rest of the treatments. Combination of fly ash has been beneficial to significantly increase the vegetative growth, floral parameters, vase life and economics as compared to control in African marigold. Therefore, it may be concluded that, fly ash can be recommended for use with fertilizer or other nutrient mixtures in marigold cultivation.

    EVALUATION OF COMBINED EFFECT OF ORGANIC MANURE AND BIOFERTILIZERS ON GROWTH AND FLORAL ATTRIBUTE OF CHRYSANTHEMUM (Dendranthema grandiflora Tzelev) CV. MAA WHITE IN POT CULTURE
    (Indira Gandhi Krishi Vishwavidyalaya, Raipur (C.G.), 2020) Sahu, Payal; Tirkey, T.; Verma, L.S.; Soni, Ravindra; Saxena, Ravi R.
    The present experiment entitled “Evaluation of combined effect of organic manure and biofertilizers on growth and floral attribute of Chrysanthemum (Dendranthema grandiflora. Tzelev) cv. Maa White in pot culture” was conducted “at Horticulture nursery and Floriculture laboratory, Department of Floriculture and Landscape Architecture, College of Agriculture, IGKV, Raipur, Chhattisgarh” during 2019-20 in Completely Randomized Design (CRD) with nine treatments and three replication constituting organic manures, onward with PSB, Azotobacter and Azospirillum and taking inorganic fertilizer as control. Although implementation of T9 (Vermicompost + Azospirillum + Azotobacter + Phosphate Solubilizing Bacteria + 50 per cent RDF) nutrient combination in potted chrysanthemum showed minimal days to first bud appearance although it significantly increased the majority of vegetative and floral characters as well as it also enhanced vase life significantly. Implementation of different nutrient condition showed tremendous difference in the vegetative, floral characters as compared to control. These nutrient mixture combinations lead to minimize the use of harmful and expensive inorganic fertilizers as well as improved the soil fertility. Therefore, it may be inferred that for organic treatments, T9 (Vermicompost + Azospirillum + Azotobacter + Phosphate Solubilizing Bacteria + 50% RDF) treatment was found to be superior and considering the performance benefits of T9 treatment in the majority of metrics in the experiment, it could be proposed for chrysanthemum pot culture combined with different nutrient combinations.
