Neorganic Rice: Same Yield, Higher Price, Up to 3x Profit

Chang-pyo Lee, World Vision Korea · South Korea

Chang-pyo Lee of World Vision Korea reports on 'Neorganic' farming (natural farming plus no-till, mulch and compost) in World Vision projects in Vietnam, Sri Lanka and Ethiopia. In Vietnam, rice yielded the same as conventional at lower input cost, and a higher selling price gave two to three times the net profit; chicken and herbs also earned more, while lettuce, broccoli and pigs fed no protein earned less. Ethiopian seed potatoes yielded more at all three cooperatives, and Sri Lankan families gained food access and diet diversity, though their yields were not significantly different from non-participants.

What they found

The question

Does 'Neorganic' farming (no or minimum till, mulching, indigenous microorganisms and compost) hold yields and raise farmer income compared with conventional farming in development projects?

How they tested it

World Vision Korea projects funded by KOICA. Vietnam (Trieu Phong): 70 households in 6 villages with 10 farmer groups, from 2015; rice pilots of 1 ha per method in each of three hamlets (Linh An, Van Toung, Ngo Xa Dong), sown January and harvested May 2016; vegetables in 5 villages of Trieu Thuong commune, November 2015 to May 2016; 100 chickens and 3 pigs per comparison. The Vietnam figures were collected by the local government. Sri Lanka (Vaharai): 600 households in 11 villages, 2013–2015, vegetables and rice; household survey in 11 villages in 2015, comparing participants before and after and against non-participants. Ethiopia (Hula): 490 households in 3 cooperatives (Gase, Wirrama, Witabono), 2014–2017, G-2 seed potato (variety Belete), 1 ha per method per cooperative, sown March and harvested July 2016. Training was a one-week trainer course once a year for government staff and lead farmers, who trained others. Plot replication, soil, and statistical tests are not stated, except significance stars on the Sri Lanka tables.

What was compared
  • Neorganic (NF) — No or minimum till, mulching, Microbes (IMO) and compost. Vietnam rice: bio-products (IMOs) 4,380,000 VND/ha; no chemical fertilizer, herbicide or pesticide. Ethiopia: compost 16 t/ha, IMO 1,100 L/ha in 11 applications plus Food (FPJ) and other natural solutions, and one late-blight pesticide spray (0.5 kg). Livestock: home-mixed feed (rice, brown rice, corn; no protein source), garden fruit and vegetables, IMO bedding for pigs.
  • Conventional (CF) — Vietnam rice: chemical fertilizer (NPK) 5,960,000 VND/ha, herbicide 330,000–350,000 and pesticide 470,000–876,667 VND/ha. Ethiopia: NPK 250 kg in 2 doses (84 USD), pesticide 1.5 kg in 2–3 sprays (17 USD). Livestock: industrial feed, vaccines and veterinary medicine.
  • Sri Lanka comparison — Project households (beneficiaries) before and after training, and against non-beneficiary households; practices on each side not detailed.
Results
  1. Vietnam rice: same yield, 11,000 vs 6,500 VND/kg, 2.3–3.3 times the net profit

    Table 5, 1 ha per method per hamlet. NF yield 6,000 kg/ha in all three; CF 6,000, 6,500 and 5,500. Income 66,000,000 VND for NF vs 39,000,000 / 42,250,000 / 35,750,000 for CF. Net profit (our arithmetic from the table): about 45.1M vs 16.3M (Linh An), 45.1M vs 20.0M (Van Toung), 45.3M vs 13.6M (Ngo Xa Dong). The gap comes from the price, not the yield.

  2. Vietnam rice input cost 6–9% lower with NF

    Total input cost 20,860,000 vs 22,660,000; 20,860,000 vs 22,260,000; 20,660,000 vs 22,136,667 VND/ha. NF paid 4,380,000 for IMO bio-products and more for caring labor (7,500,000 vs 6,000,000) but nothing for chemical fertilizer, herbicide or pesticide.

  3. Vietnam rice: less pest and disease on NF plots

    Table 4. Linh An: leaf worm 2–3 vs 15–20 per m², sheath blight none vs 20–25%, blast none vs 5–10%. Van Toung: no leaf worm or sheath blight on either; blast none vs 15%. Ngo Xa Dong: CF sheath blight 15–35%, blast 20–30%; NF cells blank.

  4. Vietnam herbs: 104.6M vs 70.4M VND profit from 7 harvests vs 5

    Table 8. Same price (50,000 VND/kg), slightly lower yield per round (420 vs 450 kg/1,500 m²), two more harvest rounds. Lettuce and broccoli, one harvest each, earned less with NF: 9.44M vs 12.66M and 35.58M vs 40.69M VND (yields 580 vs 696 kg/500 m² and 2,250 vs 2,475 kg/1,000 m²). Vegetables sold at the same price because this was their first NF season.

  5. Vietnam vegetables: much less root rot with NF

    Table 6, root rot caused by fungus: herbs 10–15% (light) vs 50–55% (very severe); lettuce 5–10% vs 25–30%; broccoli 5–10% vs 25–30%. Broccoli black aphids 20–30 vs 150–200 per m², 'jumpers' 5–10 vs 25–30.

  6. Vietnam chickens: profit 3,452,000 vs 1,126,000 VND per 100 birds

    Tables 9–10. 88 birds sold on each side, at 150,000 vs 120,000 VND each. NF input cost slightly higher (9,748,000 vs 9,434,000) because of labor (30 vs 18 working days); vaccine and vet cost 240,000 vs 1,010,000. NF birds took longer to raise; the slide rates the meat 'delicious, safer' and disease 'less, higher resistance'.

    ▶ 17:28 Said and shown on the slides

  7. Vietnam pigs: NF lost 176,000 VND on 3 pigs; CF made 145,000

    Tables 11–12. NF pigs sold at 150 kg total vs 210 kg, at 55,000 vs 43,000 VND/kg. NF input cost was lower (8,426,000 vs 8,885,000) but labor higher (17.5 vs 9 days). NF pigs had no protein in their feed (rice, brown rice, corn only); the speaker expects a small protein source to raise weight and cut raising time.

    ▶ 18:48 Said and shown on the slides

  8. Ethiopia seed potato: NF yielded more at all three cooperatives

    Table 13, t/ha including spoiled: Gase 29.0 vs 24.1, Wirrama 34.0 vs 33.0, Witabono 32.6 vs 27.8. More large tubers (over 56 mm) with NF at every site.

    ▶ 20:17 Said and shown on the slides

  9. Ethiopia: input costs about equal, net profit higher with NF

    Table 15: total input cost 1,572 vs 1,530, 1,544 vs 1,599, 1,572 vs 1,557 (USD). At an expected 1 USD/kg, net profit 27,128 vs 22,370 (Gase) and 32,256 vs 31,301 (Wirrama); Witabono about 30,400 vs 26,000 by our arithmetic. NF used one pesticide spray (6 USD) vs two or three (17 USD).

  10. Sri Lanka: yields up after training, but no different from non-participants

    Table 2, kg/plant before vs after for participants: significant gains for 6 of 8 crops, e.g. drumstick 5.84 to 9.86, ladies' finger 0.69 to 1.24, bitter gourd 1.70 to 2.59; pumpkin and green leaf not significant. Against non-participants no significance was marked; the speaker says farmer skill and environment differ too much.

    ▶ 7:16 Said and shown on the slides

  11. Sri Lanka input cost: 47.34 to 16.56 rupees per kg per plant

    Table 3: participants before vs after, difference -30.78 (P≤0.05); participants vs non-participants 16.56 vs 131.64, difference -115.08 (P≤0.05). The conclusion slide calls this '115.08% less', but it is a rupee difference.

    ▶ 8:57 From the slides

  12. Sri Lanka: food access, meals and diet diversity rose

    Access to natural produce about 20% (March 2013) to 99% of participants vs 62% of non-participants (June 2015 survey). Three meals a day 74.0% (2013) to 98.8% of children and 95.9% of adults (June 2016). Eating 4 or more of 9 food groups a day 42.3% to 63.6% of children and 78.5% of adults; children 67% vs 52% of non-participant children.

    ▶ 9:54 Said and shown on the slides

  13. Sri Lanka local statistics show NF yields above CF

    Local government statistics 2016, Mton/acre NF vs CF: ladies' finger 3.5 vs 2, brinjal 8.8 vs 8, pumpkin 5.2 vs 3.5, green chili 3.2 vs 2, beans 3.84 vs 4, bitter gourd 3.2 vs 2. The speaker notes these have no stated sampling method.

Hold it loosely
  • Project monitoring data, not controlled trials: one season, one 1 ha plot per method per site in Vietnam and Ethiopia, no replication or statistics shown for those countries.
  • The rice profit gain comes from a higher selling price (11,000 vs 6,500 VND/kg); yields were the same. The premium may not hold at larger scale.
  • Livestock comparisons are small: 100 chickens and 3 pigs per side.
  • Labor is valued at 120,000 VND per day; the NF advantage depends on that rate.
  • The Ethiopia conclusion slide says 'no significant difference', though NF out-yielded CF at all three sites; no test is shown. Income there is 'expected' at an assumed 1 USD/kg.
  • Ethiopia NF plots got one pesticide spray for late blight, so they were not pesticide-free, and 16 t/ha of compost confounds the effect of the microbes.
  • A partly legible note on the Vietnam vegetable cost slide says NF labor was higher because NF farmers plowed for land preparation and weeding, which runs against the no-till principle.
  • Sri Lanka participants and non-participants differ in skill and land, as the speaker says; the local government statistics have no stated sampling method.
For your farm
  • In these projects, rice grown with home-made Microbes (IMO) and no chemicals yielded as much as conventional rice, cost a little less, and sold for more.
  • Count your labor: making solutions and home-mixed feed takes days, and for chickens and pigs it ate most of the savings on bought inputs.
  • Pigs fed only rice, bran and corn grew less; include a protein source in home-made feed.
  • Vegetables with long harvests, like herbs, gained the most; single-harvest crops in their first season did not.
  • Home gardens raised family access to clean produce and the variety of foods eaten.

Next to Master Cho's teaching

  • Agrees

    No or minimum tillage Cho: 'In Natural Farming we do not till the land'; soil is tilled by microbes and small animals. The talk allows minimum till; Cho goes further.

    Cho, Janong Natural Farming (2003), p. 157

  • Agrees

    Mulching the soil Cho recommends rice straw mulch (not plastic): it carries microbes, suppresses weeds and holds moisture.

    Cho, Janong Natural Farming (2003), p. 74–75

  • Agrees

    Indigenous microorganisms over lab-selected strains The speaker contrasts natural farming with Korean 'microorganism farming' that applies selected strains. Cho rejects foreign or artificially selected microbes in favor of local IMO.

    Cho, Janong Natural Farming (2003), p. 89

  • Agrees

    Pigs need a protein source in home-made feed Cho says pigs on carbohydrate feed need protein and recommends Fuel (FAA) at 3–5% or maggots, never dried fish waste. The Vietnam pigs had none and sold lighter.

    2017/Advanced Cho/swine/IMG_1690 @ 0:33:10 (translated)

  • Goes further

    Natural farming lowers production cost Cho names lower cost as a core strength. The data agree for rice, but for chickens and pigs the labor of making feed and solutions offset the savings.

    Cho, Janong Natural Farming (2003), p. 61
