A Review on Crop Regulation in Guava Fruit

The influence of crop regulation on guava fruit quality (Psidium guajava) manifests in various dimensions, including physical appearance, nutritional integrity, yield, and overall productivity. This investigation explores the systematic integration of conventional and modern practices in regulating the characteristics of guava fruit. Physical appearance, including size, shape, color, and texture, is primarily influenced by targeted pruning and meticulous nutrient and water regulation. Nutritional content, encompassing essential vitamins, minerals, and antioxidants, can be enhanced and preserved through a combination of soil management, precision irrigation, and genetic engineering. Crop regulation's interplay with yield and productivity highlights the vital role of balanced pruning, efficient water and nutrient delivery systems, and modern techniques such as precision agriculture. A key finding reveals a complex challenge in maintaining a quality-quantity balance, necessitating innovation and sustainable practices for long-term benefits. This study underscores the multifaceted impacts of crop regulation on guava fruit quality and lays the groundwork for further research, emphasizing the development of integrated and sustainable strategies for optimizing both the quality and economic value of this globally significant fruit.

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.
