Step 13: Natural farming rice protocol (Part 2) - From sowing to harvesting

All our concoctions are now ready (see Part 1) and it is time to use them but... at the right concentration and the good moment. We can divide the protocol in 17 types of tasks. 

We will suppose the last harvest is finished and the rice straw are stocked
 where the tresher leaved them. Of course burning rice straw is prohibited! As a rule of thumb, "all must go back to the field except the grain (M. Fukuoka)". So all the rice straw is spread on the ricefield.We will consider Day zero as the date of transplanting so we will have dates before transplanting (DBT) and dates after transplanting (DAT). For example if the date of sowing is 18 days before transplanting we will write DBT 18.
The quantities are good for 1 ha and we use 6 backpaks (17L) per ha except for the task 1. The variety of organic rice is Masipag AG-5. As for the preparation of concoctions, use water without chlorine treatment. Spray early morning or late afternoon but not under sun.

TASK 1 - DBT 25 - LAND PREPARATION - SPRAYING MICRO-ORGANISMS
Water management: The field is not flood
Spray the 994 L EMExtended (see Part 1 for preparation), molasses and water for 1 ha of rice field.
 A power sprayer is needed for a rice field this size.



TASK 2 - DBT 25 - LAND PREPARATION - SPREADING VERMICOMPOST
If natural farming (NF) protocol is used for the first time after conventional farming, 20 bags of 50 kg per ha is recommended. As the level of organic matter increases, 15 bags are enough the second year
 and 10 the third year. It is possible to line and drag the sacks to distribute
 the vermicompost and then plow perpendicularly.

TASK 3 - DBT 25 - LAND PREPARATION - MINIMAL TILLAGE
Practice a light harrowing no more than 10 cm to disturb as less as possible the structure of the soil. Do not turn the soil. Suyod (tiller) is a good tool to do it.
From this date to the date of transplanting, the micro-organisms will recycle the rice straw and the waste of the last crop. The organic fertilization is on the way.

TASK 4 - DBT 21 - SEED & SEEDLING TREATMENT - FIRST SOAKING SEEDS
Generally a quantity of 42 kilos of seeds per ha is recommended. If only one seedling is planted 25x25 cm, 160000 seedlings are necessary. 1 kg of rice contains around 42000 grains, so 5 kg of seeds (210000 grains) are enough. Transplant 1 seedling only per hill avoid the root competition which happens with  many seedlings per hill. With square 25x25 cm roots and canopy will be greater and will not lack of oxygen.For safety I prepare 10 kg of seeds on 4 m² of beds for 1 ha of rice field.

Seeds are first soaked 8h in a mixing (for exemple 10PM to 6 AM):
OHN, 50 ml
FPJ Riceplant, 50 ml
Coconut vinegar, 50 ml
Water, 10 L

TASK 5 - DBT 20 - SEED & SEEDLING TREATMENT - SECOND SOAKING SEEDS
Put the seeds in a bag and place it under running water, or in the irrigation canal or change the
 water every 3 hours. Total soaking is 16 hours (for exemple from 6AM to 10PM, especially if changing water).

TASK 6 - DBT 20 - SEED & SEEDLING TREATMENT - INCUBATION
Incubate the seeds in the bag 36 hours (for example from 10 PM DBT 20 to 10 AM DBT 18). 

TASK 7 - DBT 18 - SEED & SEEDLING TREATMENT - SOWING
Water management of seedbeds (basins): Water basins every day. Do not water 2 days before transplanting
Seedbeds are basins 17 cm deep and 55 cm diameter with holes for drainage of water at the bottom and filled with coco coir or, if lacking, coco saw dust. One basin is equivalent to 1/4 m² of seedbed, good for 625 g of seeds and 625 m² of rice field. The advantage is an easy management (protection and transportation, stocking for replanting and no risk of flood). When it is time for
transplanting, the seedlings stay protected in the medium until the moment of transplantation. The excess of seedling can be used to prepare FPJ Riceplant. (Picture: stocking of basins with medium in the nursery before sowing).

TASK 8 - DBT 14, DBT 7, DBT 1 - SEED & SEEDLING TREATMENT -  3 SPRAYINGS
Spray the mixing every week until transplanting:
FPJ Riceplant, 25 ml
FAA, 25 ml
Water for 1 sprayer, 17L

TASK 9 - DBT 3 - LAND PREPARATION - 1 SPRAYING
Spray the field with the mixing (mixing for one sprayer 17L, need 6 sprayers for 1 ha):
EME 1:1:20, 37 ml
Molasses, 37 ml
FPJ Riceplant, 29 ml
FAA, 29 ml
OHN, 29 ml
Water for 1 sprayer, 17L
The white molds appear within 2 days acting like a vaccination of the field.

TASK 10 - DT - TRANSPLANTING (18 to 21 days after sowing)
Water management: MOIST BUT NOT FLOOD. Allow water into the field DAT 3-4
Bring the basins to the place of transplanting. One basin is good for 625 m² of rice field. After transplanting, the medium (coco coir or cco sawdust) can be reused for the next crop.
Soak the seedlings 15 seconds in a mixing:
OHN, 100 ml
FPJ Riceplant, 100 ml
Coconut vinegar, 100 ml
Water, 10 L
and transplant immediately 1/hill, 25x25cm or 30x30cm if the soil is richer in organic matter. 
Do not push the seedling and not deeper than 3 cm. The respect of the distance of planting is also very important to facilitate the mechanical weeding. Simple nylon rope with knots every 25 cm can help a good transplanting.

TASK 11 - DAT 10, DAT 25 - MECHANICAL or HAND WEEDING
If the transplanting 25x25 cm minimum is respecting, mechanical weeding
 is efficient and faster. 





TASK 12 - DAT every week, if needed - PEST MANAGEMENT
OHN is a natural pest repellent. Nevertheless, if rice pests are observed, a simple pest management program is to spray every week a mixing of Makabuhay (Tinospora rumphii) Kakawate (Gliricidia sepium) and hot red pepper.
For 1 ha or 6 sprayers, it needs:
2 kg of Makabuhay vines (picture),
10 kg of Kakawate,
4 cups of hot red pepper,
8 L of water,
1 TBS gratted soap (as sticker)
2 TBS alcohol,
6 glasses coconut milk.

The 3 plants are pounded and the water added. Soaking one night. After filtration, add the alcohol, the coconut milk and the soap. Mix thoroughly. 850 ml of the concoctions is poured in the sprayer and completed to 17L.

TASK 13 - AT VEGETATIVE STAGE: DAT 7, DAT 14, DAT 21, DAT 28  - 4 SPRAYINGS
Water management: from seedling stage up to flowering, irrigate and drain the field alternately, keeping soil saturated. The maximum level of water is 2.5 cm.
Spray the field with the mixing (mixing for one sprayer 17L, need 6 sprayers for 1 ha):
EME 1:1:20, 73 ml
Molasses, 73 ml
FPJ banana, 33 ml
OHN, 33 ml
FAA, 33 ml and LABS, 33 ml if leaves are yellowish or if stems reach 35 cm and count more than 30 leaves,
Water for 1 sprayer, 17L

TASK 14 - AT CHANGE OVER PERIOD: DAT 35, DAT 42 - 2 SPRAYINGS
Water management: Maximum level of water 5 cm
Spray the field with the mixing (mixing for one sprayer 17L, need 6 sprayers for 1 ha):
Calphos, 67 ml
FAA, 33 ml
OHN, 33 ml
FFJ, 33 ml 
Water for 1 sprayer, 17L

TASK 15 - AT CHANGE OVER PERIOD: (DAT 42), DAT 49 -  1 or 2 SPRAYINGS

Calphos, 67 ml
OHN, 33 ml
FFJ, 67 ml 
FAA, 33 ml if the rice is stunted
Water for 1 sprayer, 17L

TASK 16 - AT REPRODUCTIVE STAGE: DAT 56, DAT 63, DAT 70, DAT 77 - 4 SPRAYINGS
Water management: Gradually drain until soil level 2 to 3 weeks before harvesting
Spray the field with the mixing (mixing for one sprayer 17L, need 6 sprayers for 1 ha):
Calphos, 67 ml
OHN, 33 ml
FFJ, 67 ml 
Water for 1 sprayer, 17L

TASK 17 - AT REPRODUCTIVE STAGE: DAT 84 or 2 weeks before harvesting , when flower are bloom -  1 SPRAYING
Water management: soil is drained
Spray the field with the mixing (mixing for one sprayer 17L, need 6 sprayers for 1 ha):
Calcium, 83 ml
FFJ, 83 ml 
Water for 1 sprayer, 17L

Then, and at right time, enjoy harvesting!
