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)

Advantages of HDP

Increases yield

Improves fruit quality

Reduces labour cost resulting in low cost of production

Enables mechanization of fruit crop production

It facilitates more efficient use of fertilizers, water, solar radiation, fungicides, weedicides and pesticides

ConclusionPropagation 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

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 techniques70
