Key Features

Climate and Soil Requirements

• Pepper grows best in tropical humid regions with 25–35°C temperature and 2000–3000mm annual rainfall.
• Prefers well-drained, fertile, loamy soils rich in organic matter with pH 5.5 to 6.5.
• Avoids waterlogged, saline, or compacted soils which cause root disease.
• Partial shade protects young vines and improves microclimate.
• Gentle slopes with good drainage are ideal to prevent stagnation.
• Soil testing helps in identifying nutrient deficiencies early.
• Pineapple or banana shade trees commonly planted with pepper for protection.
• Proper site selection enhances vine longevity and productivity.
• Drainage ditches should be maintained to avoid water accumulation.

Land Preparation

• Clear land of weeds, stones, and previous crop residues thoroughly before planting.
• Deep plough or till soil to a depth of 25–30 cm for loosening and aeration.
• Incorporate 15–20 tons/ha of organic matter such as farmyard manure or compost to improve soil health.
• Level land for uniform water distribution and easier planting.
• Build support poles or trellises before planting to train pepper vines.
• Avoid planting immediately after other solanaceous crops to minimize disease risk.
• Mulch prepared beds with organic materials to conserve moisture and protect soil.
• Maintain good boundary plantations to prevent wind damage and soil erosion.
• Check pH and apply lime or sulfur to balance acidity as required.

High-Yielding and Hybrid Seed Selection

• Use certified, high-yielding, disease-resistant clones or hybrids adapted to local climatic conditions.
• Select planting material with healthy root systems and free from pests or diseases.
• Propagation usually via cuttings or grafted plants to maintain varietal purity.
• Prefer clones with good spike length and berry size for higher market value.
• Avoid using uncured or untested cuttings to reduce establishment failures.
• Purchase from certified nurseries or government approved sources.
• Monitor clone performance and switch to better hybrids regularly.
• Use pre-treated planting material with fungicides to increase survival.
• Maintain tidy nursery conditions to prevent pathogen spread.

Seed Treatment

• Treat cuttings with fungicides before planting to protect from root rots and fungal infections.
• Dip in solutions like Carbendazim or Copper oxychloride for seedling health.
• Maintain hygienic conditions in propagation beds to reduce disease incidence.
• Apply biofertilizers and growth stimulants to enhance root development.
• Store treated cuttings under shade to prevent drying or scorching before planting.
• Follow safety procedures during fungicide handling.
• Monitor cuttings for early signs of disease or pest attack.
• Use clean, disinfected tools for cutting and planting.
• Avoid over-soaking to prevent fungal growth.

Sowing and Planting Methods

• Pepper is propagated using stem cuttings, typically 20–30 cm long, planted during the start of the rainy season.
• Plant cuttings vertically or at an angle near support poles or trellises.
• Recommended spacing between plants is 2.5–3 meters in rows 2.5–3 meters apart for airflow and sunlight.
• Shade plants, particularly young vines, with banana or other shade trees.
• Use mulch to reduce weed competition and conserve soil moisture.
• Water young plants regularly to ensure establishment.
• Maintain clean planting sites free from weeds and debris.
• Remove weak shoots and train the main vine for optimal growth.
• Gap filling should be done promptly to maintain uniform density.

Nutrient and Fertilizer Management

• Integrate compost and green manures yearly to boost organic matter.
• Apply balanced NPK fertilizers based on soil test, typically 120 kg N, 60 kg P2O5, and 80 kg K2O per hectare.
• Split nitrogen doses: basal, vegetative, and flowering stages for efficient uptake.
• Supplement micronutrients like zinc, magnesium, and boron through foliar feeding if deficiencies appear.
• Avoid excess nitrogen to prevent excessive foliage at the cost of berry yield.
• Use biofertilizers such as Azospirillum to improve nitrogen fixation and root health.
• Monitor plant growth and adjust fertilizer application accordingly.
• Maintain soil pH within the optimal range for nutrient availability.
• Timely nutrient management maximizes yield and berry quality.

Irrigation and Water Management

• Pepper requires consistent moisture but is sensitive to waterlogging – well-timed irrigation is important.
• Drip irrigation ensures efficient water use and reduces disease incidence on leaves.
• Water young plants more frequently, while mature plants tolerate short dry spells.
• Avoid overhead irrigation to prevent fungal leaf diseases.
• Mulching conserves soil moisture and moderates temperature fluctuations.
• Schedule irrigation based on weather, soil moisture, and crop stage.
• Proper drainage prevents root damage and disease.
• Rainwater harvesting systems can supplement irrigation needs.
• Maintain even soil moisture for optimum fruit set and development.

Intercultural Operations

• Frequent weed removal reduces water and nutrient competition for pepper vines.
• Pruning old or dead shoots promotes new growth and improves air circulation.
• Train vines on support structures for better sunlight exposure and harvest efficiency.
