1) The document discusses guava production, including propagation methods, planting densities, pruning, fertilizer use, and post-harvest management. It provides tables showing the effects of different propagation timings, growth regulators, rooting media, and planting densities. 2) Guava is an important fruit crop in India and is known as the "Apple of the tropics". It is rich in Vitamin C and other nutrients. Common propagation methods include budding, air layering, and stooling. 3) Higher planting densities increase yields but require more intensive management. Rooting is improved by using growth regulators like IBA and selecting appropriate media. Post-harvest practices are also discussed.

INTRODUCTION
 Guava is also known as the “Apple of tropics”
 It is common fruits of the tropical and sub-tropical regions
 Guava is the fourth most important fruit of India
 It is precocious and prolific bearer, having good quality with
high nutritive value, medicinal attributes
 It is used both as fresh fruit and after processing by
preparation of jelly, toffee, candy, pulp, juice, jam, guava
nectar etc.
 It is rich source of Vitamin-C (299mg/100g)

69. Conclusion
Propagation  Air layering with treatment of IBA @ 4000 ppm with combination of
rooting media Coco peat/Sphagnum moss found better for rooting
Planting  HDP at 2.5 x 2.5 or 2.0 x 2.0 m gave more yield with better quality fruits
Manures and fertilizers  Integrated nutrient management produce the highest yield with better quality
fruits
Irrigation  Irrigation 100 % IW/CPE with NPK (60:30:30 g) combination found better for
quality characters
Pruning/Rejuvenation  Pruning intensity 60 cm and April is as time of pruning found better for quality
production
Crop regulation  One leaf pair pruning and spraying of KI @ 1 % or NAA @ 200 ppm produce
highest yield
Growth regulators/micro-nutrients  Spraying of NAA @ 60 ppm, urea @ 1%, K2SO4 @ 1%, GA3 @ 50ppm,
ethephon @ 400 ppm and ZnSO4 @ 0.4 % found better for quality parameters
Post-harvest management  Spraying of Ca(NO3) 2 1.0% and fruit treatment with 100 Gy, Coconut oil found
better for increasing shelf-life and fruit quality

70. Future thrust
Crop Improvement-
 Need to develop variety having less and soft seed as well as
seedless cultivar
 Need to develop High yielding, early bearing having good quality,
high keeping quality and insect-pest and disease resistant
varieties
 Need to develop dwarfing rootstock for high density planting
Crop production-
 Need to Standardization of training and pruning practices for HDP
Post-harvest technology-
 Need to Standardization of packaging techniques and Post harvest
techniques
