Huge amount of data and findings in here, from fully irrigated, partially irrigated and dryland cotton farmers. May be useful for the budgeting process for newer cotton farmers.

This report shows the findings of CRDC’s Survey of Cotton Growers, conducted in Spring 2016.

The survey sample:

  • 176 growers (representing 35% of the irrigated and 15% of the dryland 2015-16 crop area)
  • 2015-16 cotton – a year of limited water with a long, hot, dry finish

Key results

  • The average cotton yield was 12.4 bales/ha for irrigated cotton, 6.4 bales/ha for partially irrigated and 3.6 bales/ha for dryland.
  • Quality discounts were received on 35% of irrigated cotton farms (average $25.10, range $0.18 to
  • $130), 44% of partially irrigated (average $14.90, range $2 to $40) and 64% of dryland (average
  • $31.60, range $0.50 to $110).
  • Colour, length, and leaf were the most common causes of quality downgrades.
  • Quality premiums were received on 28% of irrigated farms (average $2.10, range $0.03 to $10), 20% of partially irrigated (average $3.90, range $1.30 to $10) and 3% of dryland (average $1.27).
  •  Whole farm irrigation water usage was on average 8 ML/ha on fully irrigated and 3 ML/ha on
    partially irrigated, giving a calculated average irrigation water use efficiency of 1.8 bales/ML on irrigated and 2.7 bales/ML on partially irrigated cotton.

Limitations to yield:

  • Verticillium wilt – 23% of farms, average 26% estimated yield loss
  • Black Root Rot – 13% of farms, average 31% estimated yield loss
  • Fusarium Wilt – 14% of farms, average 32% estimated yield loss
  • Sclerotinia – 3% of farms, average 5.5% estimated yield loss
  • Boll Rot – 11% of farms, average 13% estimated yield loss
  • Herbicide spray drift – 30% of farms, average 19% estimated yield loss
  • Hail – 22% of farms, average 33% estimated yield loss
  • Reniform nematodes, pre-applied herbicide, fertilizer burn, waterlogging, sandblasting, drought and the hot and dry finish were also reported to have limited yields.

Nutrition

Average rates of applied nutrients per ha were:

  • Irrigated cotton: 284 kg N, 35 kg P, 34 kg K, 3 kg Zn, 18 kg S
  • Partially irrigated: 126 kg N, 39 kg P, 30 kg K, 4 kg Zn, 23 kg S
  • Dryland cotton: 78 kg N, 13 kg P, 14 kg K, 2 kg Zn, 8 kg S

The range in fertilizer application rates was large and not strongly correlated with yield.
