Key Features

Climate and Soil Requirements

• Guava grows best in warm climates with an ideal temperature range of 23–28°C but tolerates 15°C to 40°C for short periods.
• Prefers sandy loam to clay loam soils that drain well and have a pH of 6.5 to 7.5.
• Guava does not tolerate waterlogging or saline soils, so it’s important to prepare the field with drainage ditches.
• Moderate rainfall (1,000–2,000 mm/year) supports Guava development; supplemental irrigation helps in dry areas.
• Guava tolerates light shade, but full sun always gives the best flowering and fruit set.
• Soil testing before Guava planting helps apply the right nutrients and avoid waste.
• Soils rich in organic content or well composted manure improve Guava growth and fruit quality.
• On steep areas, Guava should be planted across slopes to stop erosion.
• Guava adapts to light soil, but adds organic matter where soils are sandy.

Land Preparation

• Remove all weeds, stones, and debris before Guava planting to cut down pests and encourage uniform growth.
• Plough deeply – 30-40 cm – then level the plot; break clods to loosen the soil for Guava roots.
• Prepare planting pits about 60×60×60 cm, filling with topsoil, compost, and some well-mixed organic manure.
• Provide drainage channels if heavy rain is common to protect Guava plants from excess moisture.
• Guava planting in ridges or raised beds works well in low or waterlogged plots.
• Mulching during preparation keeps soil moist and discourages future weeds.
• Land layout for Guava should plan irrigation and easy access for spraying or harvest.
• Check pH and salinity, correcting with lime or gypsum as needed before Guava transplantation.
• Create windbreak rows with taller trees to shelter the Guava crop.

High-Yielding and Hybrid Seed Selection

• Choose improved Guava varieties like Allahabad Safeda, Lucknow 49, Lalit, or local hybrids for preferred color, taste, and disease resistance.
• Use seeds only if pursuing genetic diversity, as most high-quality Guava fruit come from budding or grafting nursery trees onto vigorous rootstocks.
• Always buy Guava saplings from recognized nurseries, checking for healthy, disease-free growth and true-to-type varieties.
• Guava hybrid plants usually produce more fruit and resist common diseases better than local or seed-grown trees.
• Store Guava planting material in cool, moist shade before field transplantation.
• Nurseries can do air layering, soft or hardwood cuttings, or tissue culture for mass Guava propagation.
• Ensure rootstock and scion in grafted Guava plants are well joined for strength.
• Verify Guava supply batch details – date, source, parent tree – to avoid mix-ups.
• Replace any damaged or non-growing Guava saplings quickly after planting.

Seed Treatment

• While Guava is often vegetatively propagated, treat direct-sown Guava seeds with biofungicides or mild fungicide soak to prevent seed rot and damping-off.
• Cuttings, if used, can be dipped in rooting hormone and antifungal powder to support rooting and health.
• Nursery beds for Guava should be sterilized or solarized to lower disease risks before sowing.
• Label and track all treated Guava seeds or cuttings to monitor emergence and survival rates.
• Store Guava treated seeds or cuttings in shaded, slightly humid areas before use.
• Only use registered, safe seed treatment chemicals on Guava for environmental safety.
• Clean and disinfect nursery tools after every Guava batch to avoid disease spread.
• Avoid stacking Guava plantings too close in the nursery – ventilation prevents fungal attacks.
• Follow recommended waiting periods for fungicide-treated Guava material before transplanting.

Sowing and Planting Methods

• Set Guava plants in the field at 5–6 m spacing between rows and between plants for standard varieties; closer for dwarf Guava hybrids.
• Dig pits in advance, enrich with compost and allow them to settle before final Guava planting.
• Guava saplings should be transplanted at the start of the rainy season or when irrigation is assured.
• Gently remove nursery bags, taking care not to break Guava roots during planting.
• Water Guava well at planting and mulch thickly for moisture retention and weed control.
• Avoid planting Guava saplings deeper than its previous soil mark – deep setting can rot stems.
• Fill in empty spaces with healthy Guava plants soon after initial planting (gap filling).
• Label rows by Guava variety and keep a field map for better management.
• Stake young Guava trees if in windy areas for sturdy establishment.

Nutrient and Fertilizer Management

• Guava benefits from 10–20 kg well-rotted farmyard manure per tree per year, before the rainy season.
• Apply NPK fertilizers seasonally: 250 g Nitrogen, 300 g Phosphorus, 250 g Potassium per tree, split after harvest and before flowering.
• Foliar sprays of zinc and boron help Guava fruit set in poor soils or when deficiency symptoms show.
• Guava organic mulch (leaves, grass) improves soil moisture and slowly supplies nutrients.
• Avoid overuse of nitrogen; while Guava leaves may be lush, too much can slow flowering and fruit set.
• Adjust fertilizer programs yearly based on Guava tree performance and visible deficiencies.
• Water-soluble fertilizers in drip or basin irrigation systems keep Guava nutrients available.
• Use biofertilizers – Azotobacter, phosphate-solubilizing bacteria – under Guava for eco-friendly yields.
• Record all fertilizer and manure applied to the Guava field for future improvement.

Irrigation and Water Management

• Young Guava trees need regular irrigation – every 7–10 days in dry months until well established.
• Mature Guava trees can withstand some drought, but regular watering improves flowering and fruit size.
• Avoid waterlogging, as Guava roots rot easily if soil remains overly wet.
• Drip or ring irrigation methods ensure Guava roots get enough moisture, especially in hot climates.
• Mulching reduces evaporation and keeps Guava fields cool.
• Water Guava sparingly during fruit ripening to avoid fruit splitting and fungal growth.
• Collect rainwater in ponds or tanks for Guava supplemental irrigation.
• Monitor Guava soil with a simple finger test or moisture meter.
• Plan irrigation timings to coincide with key Guava growth and fruiting stages for better yield.

Intercultural Operations

• Weed Guava fields regularly, especially after rains and early in plant life, to save water and fertilizer for Guava.
• Prune Guava annually to maintain an open canopy for sunlight and airflow, reducing pest and disease issues.
• Thin Guava fruit, if trees are overloaded, to improve size and sweetness of remaining fruit.
• Remove all diseased, damaged, or dry Guava branches as soon as noticed.
• Mulching keeps weeds down and improves soil till Guava trees mature.
• Plant short vegetable or legume intercrops between young Guava for added income.
• Always sanitize tools before and after use to avoid spreading diseases in Guava.
• Stake or support heavy branches if needed, especially when Guava fruit is large.
• Encourage beneficial insects – such as bees – to support Guava pollination.
