ABSTRACT
Aim: The objective of the research was to study the effect of Integrated Nutrient Management on the yield attributing parameters of kharif onion.Study Design: The field experiment was carried out in Randomised Block Design (RBD).Place and Duration of Study: The experiment was conducted at the Research Farm of the Department of Vegetable Science, Chandra Shekhar Azad University of Agriculture & Technology, Kanpur U.P during the kharif seasons of 2021-22 and 2022-23.Methodology: An experiment was carried out during Kharif season in the years, of 2021-22 and 2022-23 both the year same time at Vegetable Research Farm, Department of Vegetable Science, Chandra Shekhar Azad University of Agriculture and Technology, Kalyanpur, Kanpur. The experiment was laid out in randomized block design with three replications. The treatments consisted of T1- Control: T2- 100% RDF (NPK @ 120:60:80 kg/ha; T3- 75% RDF+ FYM 6 t/ha: T4- 75%RDF+ Vermicompost@2 t/ ha; T5- 75%RDF+FYM @ 3t/ha+vermicompost@1 t/ha ;T6- 75% RDF + FYM @ 3 t/ha + Vermicompost @ 1t/ha+ Biofertilizer (Azotobacter + PSB @ 5 kg/ha each):T7? 50% RDF + FYM @ 12t/ha; T8-50% RDF + Vermicompost @ 4t/ha: T9- 50%RDF+ FYM @ 6t/ha + Vermicompos @ 2t/ha: T10- 50%RDF + FYM @ 6t/ha + Vermicompost @ 2t/ha + Biofertilizer (Azotobacter + PSB @ 5 kg/ha each).Results: Results revealed that the treatment T10 (50% RDF +FYM @ 6 t/ha + Vermicompost @ 2t/ha+ Biofertilizer (Azotobacter + PSB @ 5kg/ha each) performed better with respect to yield attributing parameters characters such as Average bulb weight, A, B, C grade bulb percentage, days takes to harvesting, bolting percentage of bulb and double bulb Percentage.Conclusion: The study underscores the crucial need to shift towards Integrated Nutrient Management (INM), incorporating both organic and inorganic fertilizers. This transition is essential to protect soil fertility, maintain ecosystem health, and ensure sustainable food production for future generations.
ABSTRACT
Aim: The objective of the research was to study the effect of Integrated Nutrient Management on the vegetative growth of sprouting broccoli (Brassica Oleracea L. Var. italica) Var. Green Magic.Study Design: The field experiment was conducted in Randomised Block Design (RBD).Place and Duration of Study: The experiment was conducted at the Research Farm of the Department of Vegetable Science, Chandra Shekhar Azad University of Agriculture & Technology, Kanpur U.P during the Rabi seasons of 2021-22 and 2022-23.Methodology: During bed preparation, the required quantity of farmyard manure (FYM), vermicompost and biofertilizers was mixed into the soil in individual specified plots according to the treatment. The treatments included T0: Control, T1: 100% RDF @ 120: 80: 60, N: P: K (kg/ha), T2: 75% RDF + 25% N through FYM, T3: 75% RDF + 25% N through Vermicompost, T4: 75% RDF + 25% N through FYM + Biofertilizer, T5: 75% RDF + 25% N through Vermicompost + Biofertilizer, T6: 75% RDF + 12.5% N through FYM + 12.5% N through Vermicompost, T7: 75% RDF + 12.5% N through FYM + 12.5% N through Vermicompost + Biofertilizer, T8: 50% RDF + 50% N through FYM, T9: 50% RDF + 50% N through Vermicompost, T10: 50% RDF + 50% N through FYM + Biofertilizer, T11: 50% RDF + 50% N through Vermicompost + Biofertilizer, T12: 50% RDF + 25% N through FYM + 25% N through Vermicompost and T13: 50% RDF + 25% N through FYM + 25% N through Vermicompost + Biofertilizer. Observations were recorded on plant height (cm) and plant spread (cm) at 30 DAT, 60 DAT and at maturity and on stalk length (cm) and stalk diameter (cm) at maturity.Results: The treatment T11: 50% RDF + 50% N through Vermicompost + Biofertilizer outperformed all the other treatments in terms of plant height (cm), plant spread (cm), stalk length (cm) and stalk diameter (cm).Conclusion: The study emphasizes the vital necessity of transitioning to INM with organic and inorganic fertilizers to preserve soil fertility, ecosystem health, and sustainable food production for future generations.
ABSTRACT
P. fluorescens strain Psd was isolated from the rhizosphere of Vigna mungo and evaluated for its multiple plant growth promoting and biocontrol properties against F. oxysporum. Interestingly, this strain not only produces a range of antimicrobial compounds but also solubilizes complexed phosphates and synthesizes phytohormone (IAA). These properties can be assessed to elucidate the agronomic significance and rhizospheric competence of this soil isolate. Biocontrol action has been demonstrated in vitro against some other rhizospheric bacteria, and a phytopathogenic fungus along with wild type E. coli K-12. Genetic evidence for the antimicrobial status of strain Psd has been derived in terms of elucidating a unique combination of phenazine and pyrrolnitrin biosynthesis genes, not reported for any other P. fluorescens strain. The conserved part of antibiotics biosynthesis operon has been PCR amplified, cloned, sequenced and phylogenetic relationship based on similar genes from a few known Pseudomonads has been derived. The properties possessed by strain Psd may enable the bacterium to establish itself successfully in the rhizosphere.
