Sunflower Production Guide

Best Package and Practices of Sunflower High Production

Achieving high production of sunflowers requires a combination of the right package and practices. To start, choose a high-yielding variety and ensure the soil is well-drained, rich in organic matter, and has adequate fertility. Proper seedbed preparation, timely planting, and weed control are critical for a successful crop.

Regular monitoring for pests and diseases and proper management of irrigation, fertilization, and harvest are also key factors for maximizing production. Growers of sunflowers can get the best yields and quality by following these steps. This makes sunflowers a profitable and rewarding crop to grow.

Land Preparation

Land preparation is an important aspect of growing sunflowers. Plowing and harrowing, the addition of well-decomposed organic matter are recommended practices. Plough once with a tractor and twice with an iron plough until all the clods are fine tilled.

Temperature Requirements

Sunflowers require a temperature range of 20°C to 30°C for optimal growth.

Climatic Requirements

Plenty of sunshine and moderate to low humidity levels are ideal for sunflowers.

Rainfall Requirements

Sunflowers can tolerate drought conditions but require 500-600 mm of rainfall during the growing season.

Propagation Method

Sunflowers are propagated through seeds.

Seed Quality

High-quality seeds with good germination rates and certified and free from diseases are necessary for the successful growth of sunflowers.

Seed Treatment for Sunflower

Fungicide treatment is recommended to protect against seed-borne diseases. Soak seeds in 2% ZnSO4 for 12 hrs and shade dry for rainfed sowing. Treat the seed with Trichoderma @4g/kg just before sowing. Treat seeds with 2 g/kg Carbendazim or Thiram 24 hours before sowing. Using rice kanji as a binder, treat seeds with three packets of Azospirillum (600 g/ha) and 3 Phosphobacteria (600 g/ha) or six packs of Azophos (1200 g/ha).

Seed Rate for Sunflower

The recommended seed rate for sunflowers is an average of 3-4 kg per acre. For rainfed sowing, the recommended rate for varieties is 7 kg/ha, and for hybrids is 5 kg/ha. The recommended rate for varieties for irrigated sowing is 6 kg/ha, and for hybrids, it is 4 kg/ha. Sunflower oilseed plant populations should range between 15,000 and 22,000 plants per acre.

Spacing for Sunflower

Sunflowers should be spaced according to the variety. For hybrids, the spacing should be 60 cm x 30 cm, and for varieties, it should be 45 cm x 30 cm. Cover the fertilizer mixture-filled furrows with soil and plant the seeds 3 cm deep. Two seeds per hill.

Sowing Method for Sunflower

Sunflowers can be directly sown into the soil by broadcasting or drilled in rows spaced at 60-75 cm apart. Alternatively, ridges and furrows can be formed. Form ridges and furrows 6 m long using a bund-former or ridge plough according to the field’s topography.

Thinning Operation in Sunflower

After the 10th day of sowing, thin out seedlings and leaving only one healthy and vigorous seedling on each hill.

Manure & Fertilizer Application in Sunflower

To prepare the soil for sunflower cultivation, it is recommended to spread 20-25 tons of farmyard manure per acre or Before the last tillage, spread 12.5 t/ha of FYM, compost, or composted coir pith. For good mixing, use a country plough.

It is recommended to apply a basal dose of 60 kg N, 40 kg P2O5, and 40 kg K2O per acre for sunflowers with essential nutrients. Additionally, 30 kg N per acre top dressing should be done 30-35 days after sowing. Farmers can follow the blanket NPK/ha for irrigated and rainfed crops if soil test recommendations are unavailable.

Weed Control in Sunflower

Weed control in sunflower cultivation can be achieved through manual weeding, herbicides, or intercropping with leguminous crops. Hand weeding may also be done twice at 20 and 40 days after sowing to remove weeds that escape herbicide treatment.

Herbicide Application in Sunflower

Pre-emergence application of Pendimethalin or Glyphosate is recommended for effective weed control in sunflower cultivation. Fluchloralin should be applied at 2.0 l/ha before sowing and incorporated or applied as a pre-emergence spray on five days after sowing, followed by irrigation or apply Pendimethalin as a pre-emergence spray three days after sowing. For post-emergence control of weeds, Glyphosate should be applied at 1.0 kg/ha before the crop attains a height of 30 cm.

Cropping Systems in Sunflower

Sunflowers can be cultivated using monoculture, intercropping, or crop rotation methods depending on the farmer’s preference and suitability for the region.

Irrigation Methods and Scheduling in Sunflower

Furrow, drip, or sprinkler irrigation methods can be used in sunflower cultivation to ensure adequate moisture for the crop’s growth.

Irrigation Scheduling in Sunflower is frequent irrigation during the flowering stage is recommended for sunflower cultivation, with 6-7 irrigations required during the crop cycle.

Disease Control in Sunflower

Sunflowers are susceptible to various diseases, including Downy Mildew, Rust, Sclerotinia Head Rot, Charcoal Rot, Verticillium Wilt, Alternaria Leaf Spot, Bacterial Leaf Spot, Powdery Mildew, Fusarium Wilt, and Head Rot. Fungicides like Mancozeb or Copper oxychloride, crop rotation, and field sanitation. To control downy mildew and rust, spray Mancozeb or Metalaxyl at two g/lit of water.

Pest Control in Sunflower

Sunflower plants are prone to infestations from several types of pests; major pest includes aphids, jassids, banded sunflower moth, sunflower stem weevil, sunflower beetle, cutworms, and heliothis. If not controlled, these pests can cause significant damage to the plants, affecting yield and quality.

Various insecticides like Imidacloprid or Thiamethoxam and Bt cotton can be used to manage pest infestations. To control aphids, jassids, and whiteflies, spray Imidacloprid or Thiamethoxam at 0.3 ml/lit or Acetamiprid at 0.3 g/lit of water. For controlling stem weevils, spray Carbaryl at 2.0 g/lit or Fipronil at 0.3 ml/lit of water.

Harvesting and Threshing of Sunflower

Sunflower plants usually reach maturity 100-120 days after sowing. Harvesting should be done when the heads have ripened and the bracts turn yellow. To judge when to harvest sunflowers, observe the bracts on the backside of the capitula. Harvest when they turn lemon yellow and the heads harden.

Sunflower Yield Per Acre

Several factors affect the yield of sunflowers per acre, including soil type, weather conditions, disease and pest pressure, and agronomic practices used. On average, a yield of 1,000-1,200 kg per acre can be expected. However, with proper management practices, it is possible to achieve higher yields.
