Thoroughly till the soil to facilitate easy seed penetration and germination. As a preventive measure against nursery damping off and to enhance seed vitality, immerse the seeds in a solution comprising AFRIKELP (2ml per liter of water) and RODAZIM (1ml per liter of water) for four minutes before sowing.

When planting seeds like Cal J tomatoes, ensure they are not buried too deeply but instead lightly covered with a thin layer of soil. Utilize your finger to create planting rows, ensuring optimal spacing of around 15cm between rows. To enhance moisture retention, consider covering the bed with hay or dry grass, which also aids in reducing water splash during irrigation.

Optimal watering practices entail irrigation in the morning, with seeds expected to germinate within 8-10 days. Sustain watering until a week or two prior to transplanting, gradually reducing irrigation to facilitate seedling hardening. Typically, seedlings are primed for transplanting after approximately one month of growth.

Regular scouting for pests and diseases is imperative during the nursery stage, enabling early detection and treatment for enhanced survival rates. By meticulously preparing the nursery bed and implementing diligent care practices, growers can nurture robust tomato seedlings poised for successful transplantation and subsequent cultivation.

Transplanting and Planting

Two days prior to transplanting, administer AFRIKELP (2ml per liter) to the seedlings to facilitate swift recovery from transplant shock. Transplantation should be conducted when seedling stems reach a diameter of 4-6 millimeters or achieve a height of approximately one foot, ensuring the exclusion of weak or diseased plants.

For optimal spacing, plant the seedlings at intervals of 45 centimeters by 60 centimeters. Dig planting holes to a depth of 6 inches, incorporating any manure carefully into the soil before planting. Apply DAP fertilizer at a rate of 80 kilograms per acre to bolster soil fertility.

To address soil-borne insect pests and fusarium wilt, drench the soil with a solution comprising IMAXI (15ml per 20 liters) and RODAZIM (20ml per 20 liters) before planting.

Upon removal from the nursery bed and thorough watering, shelter the seedlings in a shaded area away from direct sunlight. Plant each seedling individually, covering the roots with soil and firmly compacting the soil around them. Water adequately but avoid excessive watering, ensuring optimal conditions for successful transplant establishment.

Fertilization and Watering

After four weeks, perform a top-dressing of either CAN or UREA at a rate of 50 kilograms per acre to nourish the plants. Ensure diligent weed control, particularly within the initial 30 days of growth, avoiding hand weeding to prevent root damage. Apply AMBAR at a dosage of 30 milliliters per 20 liters between rows and plants to suppress weed germination and eliminate broad-leafed weeds, utilizing the appropriate nozzle for optimal efficacy. It’s essential to apply AMBAR when weeds are below 4 inches in height and smaller than the tomato plants for best results.

During the flowering stage, administer another application of Harmony at a rate of 30-40 milliliters per 20 liters, targeting the flower buds. Optionally, mix Harmony with soluble foliar fertilizers high in potassium and calcium to mitigate calcium end rot and other fruit-related diseases while safeguarding against flower and fruit abortion. Following the flower setting phase, refrain from applying nitrogen-rich fertilizers such as CAN, NPK, or Urea.

Maintain adequate soil moisture through irrigation, ensuring the soil remains moist without becoming saturated or muddy. An irrigation schedule of twice a week, utilizing 10,000 to 20,000 liters per acre, is typically sufficient for optimal tomato growth and development.

Disease Control

Vigilantly monitor the crop for signs of blight, mildew, and canker, especially during cool and wet conditions when blight is most prevalent. As a preventive measure against blight, apply an early spray of Stage at a rate of 20 milliliters per 20 liters of water, repeating the application after 7 days if weather conditions remain cold and wet. Continuously scout for disease symptoms thereafter, applying Stage 250 EW in weekly intervals if any signs of disease are detected. Enhance plant vigor and stress recovery by incorporating Harmony at a rate of 30-40 milliliters per 20 liters in each application of Stage.

Conduct daily inspections for signs of insect damage, particularly during warm and dry conditions. Serious pests such as spider mites, leaf miners (tuta absoluta), thrips, whiteflies, caterpillars, and aphids pose significant threats to the crop and should be diligently controlled. Additionally, inspect vegetation surrounding the field perimeter for potential pest infestations.

To effectively manage aphids and worms, especially during fruit set, administer a spray of JACKPOT at a rate of 12.5 milliliters per 20 liters of water. For stubborn leaf miners and red spider mites, employ a mixture of ROMECTIN (20ml/20ltr) and IMAXI (12.5ml/ltr). Control whiteflies by applying BAMAKO at a rate of 5 grams per 20 liters of water, targeting both the crop and field edges, particularly in the evening.
