Pepper (Capsicum annuum L.) Fertilization Program

Integrated Nutrition Program with Arwin Tarım Products

Summary

High yield and market quality in pepper cultivation are achievable through a balanced and sustainable nutrition program aligned with the plant’s growth stages. This fertilization program, developed by Arwin Tarım, is prepared based on the physiological needs of pepper plants from transplanting to the end of harvest. The program aims to accelerate root development, reduce flower drop, prevent blossom end rot, and ensure high-quality fruit production.

1. Introduction

Pepper (Capsicum annuum L.) is a vegetable crop sensitive to nutrient imbalances. Incorrect timing and ratios of nitrogen (N), phosphorus (P), potassium (K), and calcium (Ca) can lead to flower drop, irregular fruit formation, and blossom end rot. To prevent these issues, Arwin Tarım offers an integrated, product-based fertilization approach tailored to the phenological growth stages of pepper plants.

2. Growth Stages of Pepper and Arwin Tarım Solutions

2.1 Transplanting & Rooting Stage (Adaptation)

Objective: Reduce transplant stress and establish a strong root system.

Root development at this stage determines the plant’s nutrient uptake capacity throughout the season. Phosphorus and organic matter-supported applications accelerate rooting and minimize seedling stress.

Arwin Tarım Application:

  • BRANGUS (60% Organic Matter, 12% Free Amino Acids)
  • GOLD P (Phosphorus-based root developer)
Expected Result: Fast adaptation, dense fibrous roots, and uniform plant growth.
2.2 Vegetative Growth Stage (Forking & Branch Formation)

Objective: Strengthen the plant framework and build healthy foliage.

Balanced nitrogen nutrition is critical in this stage. Instead of single-form nitrogen, products containing multiple nitrogen forms should be preferred to match the plant’s needs.

Arwin Tarım Application:

  • Three-N (Ammonium + Nitrate + Urea Nitrogen)
  • KEROTİN L (Foliar stress & enzyme activity support)
Expected Result: Strong stems, vigorous branching, and dark green healthy leaves.
2.3 Flowering & Fruit Set Stage

Objective: Reduce flower drop and support healthy, uniform fruit setting.

This is the most critical phase in pepper cultivation. While nitrogen is reduced, phosphorus and calcium applications become more prominent.

Arwin Tarım Application:

Expected Result: Prevention of blossom end rot, uniform and firm fruits.
2.4 Fruit Enlargement & Harvest Stage

Objective: Increase fruit size, flesh thickness, and market value.

During harvest, the plant produces new flowers while enlarging existing fruits. Therefore, potassium and energy demand is high.

Arwin Tarım Application:

  • GRAND K (High potassium content)
  • FULL FRUIT (Plant-based quality enhancer)
  • BRANGUS (Supports soil structure and root health)
Expected Result: Thick-fleshed, heavy, glossy fruits with long shelf life and strong market suitability.
