National Horticultural Fair 2021-A Success Story

The ICAR-Indian Institute of Horticultural Research, Hessaraghatta, Bengaluru, organized five- day National Horticulture Fair (NHF 2021) from February 8th to 12th   with the theme ‘Horticulture: for start-up and standup India’ in collaboration with several agencies. The fair was held on a dual mode with the approaches of virtual and physical. The virtual mode had the officials of ICAR Institutes, Horticulture Universities, Directors of State Horticulture Departments, Heads of KVKs and representatives from private industry, press personnel, farmers and students attending the event. The event had 255 demonstration plots of various varieties/technologies developed by the Institute. The problems related with the growing of horticultural crops in various regions of the country were addressed by the experts through live video interaction with the help of the demonstration plots.  A total viewing of 54 lakhs was recorded during the five days of this fair, which included one way communication viewing through social media net\\\\work (14,50,000), video conference viewing through 7000 logins in various places of KVK’s, FPO’s and Sri Sri Institute of Agricultural Sciences & Technology Trust accounted for a total primary source viewing was 4,20,000. The reach from the secondary sources through the subscription to our YouTube channel (followers) was 38.20 lakhs. Viewership was also noticed from 11 different countries. The footfall for the physical fair was 56,000. Publicity preceding the fair by way of animated videos, press and media played a great role in making the fair successful as commercialization of 12 technologies also took place. Various private and public institutions as well as entrepreneurs who have purchased the technology from the Institute got an opportunity to display their products. The modus operandi and the details of methodology are discussed

Not AvailableThe production of weak organic acids by microorganisms has been attributed as the prime reason for the solubilization of insoluble phosphates under both in vitro and soil conditions. Literature seems to be heavily biased towards gluconic acid production by microbes and its subsequent release into the environment as the key factor responsible for phosphate solubilization. This has found credibility since gluconic acid being a product of the Kreb?s cycle is often detected in large quantities in the culture media, when assayed under in vitro conditions. In the present work, the organic acid profiles of four elite phosphate solubilising isolates were determined in the presence of different insoluble sources of phosphates, under in vitro buffered culture conditions by HPLC (High-Performance Liquid Chromatography). While most previous studies did not use a buffered culture media for elucidating the organic acid profile of phosphate solubilizing bacterial isolates, we used a buffered media for estimation of the organic acid profiles. The results revealed that apart from gluconic acid, malic acid is produced in significant levels by phosphate solubilizing bacterial isolates, and there seems to be a differential pattern of production of these two organic acids by the isolates in the presence of different insoluble phosphate sources

Not AvailableA study was conducted to investigate the effects of paclobutrazol (PBZ) (1.25 g a.i m-1) on the contents of non-enzymatic antioxidants, ascorbic acid, glutathione (GSH) and phenols and activities of antioxidant enzymes, peroxidase, catalase, superoxide dismutase and ascorbate peroxidase in buds and leaves of growing shoots of mango cv. Totapuri at four distinct phenological stages numerically represented as 510 (initiation of bud swelling), 511 (Swollen buds), 513 (bud burst) and 515 (panicle emergence) as per BBCH scale. The paclobutrazol treatment increased in non-enzymatic antioxidants, ascorbic acid (5.0487.61%), total phenol (5.74-65.65%) and GSH (5.08-38.7%) contents buds and leaves and activities enzymatic antioxidants, peroxidase (33.0-266.9%), SOD (44.3-198.0%), catalase (68.0-301.6%), and ascorbate peroxidase (22.8-99.0%) in buds at various phenological stages. The paclobutrazol induced increase in ascorbic acid and GSH was high at 511 and in total phenols at 513 stages in the developing buds. With respect to bud growth stages, activities of enzymatic antioxidants, peroxidase and ascorbate peroxidase were high at 511 stage and the SOD activity at 510 stage under paclobutrazol treatment. The catalase activity witnessing consistently increasing trends in developing buds was high at panicle emergence (515 stage). There was broad similarity in the trends of non-enzymatic and enzymatic antioxidants antioxidant contents in the developing buds of paclobutrazol untreated and treated trees. From the results, it was apparent that the mango flowering coincides with increase in non-enzymatic and enzymatic antioxidants, and a high antioxidant status induced by paclobutrazol is responsible for its floral responses.Not Availabl

Not AvailableA study was conducted to evaluate the effect ofseed treatment with bacterial strains ofEnterobacterspp.on seed germination and seedling growth of two tomato(Solanum lycopersicumL.) cultivars (cv. Arka Meghali andcv. Pusa Ruby). The cultivar Arka Meghali is recom-mended for rainfed conditions, while cv. Pusa Ruby isgrown under irrigated conditions. Seeds were treated withosmotolerant plant growth promoting bacterial strainsbelonging to the genusEnterobacter(P-39, P-41 and P-46),for a period of 24 h and subsequently incubated at 25°Cunder different mannitol induced osmotic stresses (0,-0.2,-0.4,-0.6,-0.8,-1.0 MPa). Seed treatment with bac-terial strains influenced the germination and seedling vig-our index of both cultivars as compared to the untreatedand hydro-primed seeds, up to-0.6 MPa. The response ofEnterobacterstrains to water stress was better in cv. PusaRuby as compared to cv. Arka Meghali as indicated byhigher germination percentage and germination rate. Theseeds of both cultivars treated withEnterobacterP-39performed better under osmotic stress (up to-0.6 MPa incv. Arka Meghali and-0.8 MPa in cv. Pusa Ruby), indi-cating the significance of this strain as compared to otherbacterial strains studied. The bioprimed seeds that failed togerminate at osmotic potentials beyond-0.4 MPa, whentransferred to water (0 MPa), recorded improved germi-nation and seedling vigour. These results indicated that thetreatment of seeds with osmotolerant plant growthpromoting bacterial strains improved the germination andenhanced seedling growth under osmotic stress conditions.Not Availabl

Not AvailableVariation in leaf morphology and physiological characteristics was studied in six genotypes of Annona, namely A. atemoya, A. cherimola, A. glabra, A. muricata, A. reticulata, and A. squamosa (‘Balanagar’). The genotypes differed significantly in their leaf morphology and gas exchange: specific leaf weight was maximum in A. muricata and A. reticulata; leaf area, in A. cherimola; and net photosynthesis, in A. squamosa. Water use efficiency, relative water content, epicuticular wax content, and stomatal density on abaxial and adaxial surfaces of leaves were maximum in A. glabra (although the density was equally high in A. squamosa) whereas chlorophyll a, chlorophyll b, and total chlorophyll content were maximum in A. squamosa. These differences may prove relevant in selecting Annona genotypes for adaptation to different agro-climatic regions.Indian Institute of Horticultural Researc
