Effect of Soil Propagation Media and Bio-fertilizers on Seedling Germination and Seedling Vigour in Aonla (Emblica officinalis Gaertn.)

Aims/ Objectives: Effect of soil propagation media and bio-fertilizers on seedling germination and seedling vigour in Aonla.Study Design: Completely Randomized Block Design.Place and Duration of Study: Research Field, Department of Fruit Science, College of Horticulture, Mandsaur, Madhya Pradesh during 20th February 2021 to 05th April 2021.Methodology: The experiment was laid out using Completely Randomized Block Design with 18 different combinations of growing media. In the preparation of media and filling of polybags the soil was sieved and mixed FYM, Vermicompost and Neemcake in the ratio of 1:1:1:1 then added the bio-fertilizers.Results: In this study we found that treatment GM18- Soil + Neemcake + Vermicompost + FYM + Rhizobium + Trichoderma spp. @ 2.5 g found minimum days taken to seed germination (10.00 days), maximum number of seedlings sprouted (13.32), maximum survival percent (81.03%), maximum germination percentage (94.54%), maximum seedling height (8.94 cm), maximum number of leaves per plant (7.27), maximum leaf area (17.80 cm2),maximum fresh weight of shoot (4.34 g), maximum dry weight of shoot (2.21 g), maximum length of roots (7.21 cm), maximum diameter of roots (1.05 mm), maximum fresh weight of roots (1.04 g), maximum dry weight of root (0.44 g), maximum speed of germination (7.56), maximum mean daily germination (3.53), maximum peak value (1.33), maximum germination value (4.68).Conclusion: On the basis of results obtained in present investigation it is concluded that treatment GM18 (Soil + Neemcake + Vermicompost + FYM + Rhizobium + Trichoderma spp. @ 2.5 g) was found to be the best for seed germination characters and seedling vigour characters.Directions of Further Use: The experiment should be done with different concentrations of growth regulator to find the best combination.

Evaluate the Effect of Integrated Nutrient Management (INM) on the Economic and Physical Attributes of Aonla (Emblica officinalis Gaerten)

The present investigation was conducted to Evaluate the effect of Integrated Nutrient Management (INM) on the Economic and Physical attributes of Aonla (Emblica officinalis Gaerten). The research was carried at Main Experiment Station, Horticulture, Acharya Narendra Deva University of Agriculture and Technology, Kumarganj, Ayodhya (U.P.) during the year 2021. It was laid out in a randomized block design with 10 treatments, namely: T1 – Control, T2- RDF 100% (1kg.N: 0.5kg.P:1kg.K per tree), T3- FYM (10kg./tree) + RDF 100%, T4- Poultry Manure (7.5kg./tree) + RDF 100%, T5- FYM (10kg./tree) + RDF 50% + Azospirillium (10ml./tree), T6- Poultry Manure (7.5kg/tree) + RDF 50% + Azospirillium (10ml./tree), T7 -FYM (10kg./tree) + RDF 50% + PSB (10ml./tree), T8- Poultry Manure + RDF 50% + Azospirillium (10ml./tree), T9 –FYM (10kg/tree) + RDF 50% + Azospirillium (10ml./tree) + PSB (10ml./tree) and T10- Poultry Manure (7.5kg/tree) + RDF 50% + Azospirillium (10ml/tree) + PSB (10ml./tree).The experiment was replicated three times. Results showed treatment T10 outperformed the rest with maximum fruit set percent (78.56%), fruit retention (20.29%), fruit yield (102.78 kg/tree), fruit weight (41.89 g), fruit length (3.87 cm), specific gravity (1.05 g/cm3 ) and maximum gross return/ha Rs. (128264), Net return Rs. (92154) and Cost: benefit ratio was evaluated with the use of treatment combination T10. Thus, the treatment combination T10 is therefore recommended for application to Aonla trees in eastern Uttar Pradesh in order to obtain high yields with better quality fruits.
