Wednesday September 1st: Yesterday, 200 days after the prune, new photos were taken (today uploaded). I think harvest will be more difficult since so "closed" crop.
Monday July 5th. Last week a third attack by broad mite in the season. Directed spraying was done to control last saturday.
Three months after prune mealy bugs are presents again, too the worse attack by broad mite in the 14 months of the crop. This week the season's second insecticide/miticide treatment was done.
Since last weekend some plants shown the first inflorescences.
Photos from all the items tell above was uploaded yesterday.

April 17th, 2010: Two months after the prune, most of the plants with 30 to 35 branches 60-80 cm long. Yesterday 180 grams of Nitrofoska*Perfekt (15-5-20 fertilizer) was supplied any plant.
Yesterday, 19th March 2010, our plantation it was completed it´s first year plus one day. This day we need to apply to control mealy-bugs (maybe Phenacoccus sp.; most motil larvae), thrips (only larvae present, apparently Frankiniella sp.) and an incipient "atack" from broad mite.
Today I was uploaded five photos.
Monday February 22th, 2010.
On February 12 the prune was done, trying to cut 33 cm above the soil surface. Two photos uploaded today was taken these day, the other two was taken 10 days after.
Federico,
First season any plant had 5 to 15 secondary branches, we assume an avarage of 9 including the leader; all stem developed naturally without prune. Yes I wait 3 to 4 laterals from any cuted branch (from our previuos experience, please check: http://biofuelexperts.ning.com/forum/topics/the-first-pruning-experience). I have seen 3 to 7 nodes down the cuts (3 to 7 cm between each).
Thanks for uploading the information. You are showing the community a very detailed record on your experimental trial. Excellent Job!
1) How many nodes have you left under the cut? I hope all branches will give 2 ore 3 secondary brunches.
2) How many lateral braches has the plant developed naturally? It seems they already have 5-7 brunches on average.
Best regards,
Federico Maria Grati
Tuesday February 2nd, 2010. Last night and today morning a drizzle was present wetting the soil surface. We take it to apply pre-emergence herbicide previuos to the prune. Two photos was uploaded.
So low yield on the fifth harvest: 3 to 5 g per plant, 76 to 193 kg/ha. Today I uploaded some photos shown the actual appearance of the crop, and the stored fruit ready for "decortication". No later than two weeks we will prune the plants. INES BAZAN
SORRY, the figures for yield per plant on the last two harvest are wrong: the fourth harvest was 73 to 100 g, and the fifth 32 to 55 g.
INES
Very poor results on the fourth harvest (December 21th to 24th, 280 dat): 7 to 10 grams per plant, after it the yields ranging from 2.3 to 3.0 tons per ha. First to second January week the last harvest will be held.
Las week, December 7 to 11th, the third harvest was done. Dry seed yield for it: Plant spacing, 3.5 X 1.5 m = 253 g per plant ( 482 kg/ha ) / 3.5 X 1.2 m = 280 g per plant ( 667 kg/ha ) / 3.5 X 1.0 m = 232 g per plant ( 664 kg/ha ) / 3.5 X 0.75 m = 201 g per plant ( 766 kg/ha ). After three harvest the accumulated dry seed yields are: Plant spacing, 3.5 X 1.5 m = 1,137 g per plant ( 2,166 kg/ha ) / 3.5 X 1.2 m = 1,149 g per plant ( 2,736 kg/ha ) / 3.5 X 1.0 m = 785 g per plant ( 2,245 kg/ha ) / 3.5 X 0.75 m = 635 g per plant ( 2,422 kg/ha ).
Jose Ines: Hasta ahora estoy dando los primeros pasos. Entiendo que este es un esfuerzo de largo aliento. Tambien, que es necesarios una etapa de experimentacion para determinar aspectos tecnicos y economicos del cultivo. Cuentame por favor, como es tu plan de desarrollo y que etapas tienes programadas. Otras inquietudes tienen que ver con: a) Seleccion de semillas (porque escogiste la de Cambodia ?, b) Que rendimientos por hectarea esperas obtener, c) que area de cultivo has determinado como minima (critica) para obtener una rentabilidad aceptable ?
Muchas gracias por tu ayuda. Saludos. German
Germán:
Espero poder reponder todas tus dudas. Empezando por la semilla, la verdad es que tuvimos suerte de que el ecotipo que trajimos tenga tan buen desempeño, y digo suerte pooque de los varios materiales que podíamos importar (en ese momento YO no pude conseguir semilla en el país) este lote fue el de menor precio. La idea original era hacer una plantación de 10 ha pero con la baja germinación que tuvimos apenas nos alcanzó para las 2.5 ha que tenemos.
Desde que iniciamos y hasta la fecha solo nos estamos enfocando en los aspectos agronómicos aunque todas las actividades e insumos están registradas y solo será cuestión de costearlas. Yo tengo confianza en que este cultivo será viable económicamente manejado bajo un esquema intensivo como el que estamos proponiendo.
Sobre los rendimientos yo espero que en este primer ciclo superemos ampliamente las 3 ton/ha, en unos minutos más subo los resultados del tercer corte.
Gracias por tu interés y saludos.

November 23th to 27th the second harvest was done. Dry seed yields for it were: Plant spacing, 3.5 X 1.5 m = 170 g per plant ( 324 kg/ha ) / 3.5 X 1.2 m = 409 g per plant ( 974 kg/ha ) / 3.5 X 1.0 m = 172 g per plant ( 492 kg/ha ) / 3.5 X 0.75 m = 249 g per plant ( 952 kg/ha ).
Then, the accumulated dry seed yields for the two harvest are: Plant spacing, 3.5 X 1.5 m = 884 g per plant ( 1,684 kg/ha ) / 3.5 X 1.2 m = 869 g per plant ( 2,069 kg/ha ) / 3.5 X 1.0 m = 553 g per plant ( 1,581 kg/ha ) / 3.5 X 0.75 m = 434 g per plant ( 1,656 kg/ha ).
After the first harvests (only dry fruit pick-uped), there are the yields:
Plant spacing, 3.5 X 1.5 m = 714 g per plant ( 1,360 kg/ha ) / 3.5 X 1.2 m = 460 g per plant ( 1,095 kg/ha ) / 3.5 X 1.0 m = 381 g per plant ( 1,089 kg/ha ) / 3.5 X 0.75 m = 185 g per plant ( 704 kg/ha ).
Ten to twelve days after it we are ready for the second harvest (only dry fuit, again)

NOTE:
The yields are DRY SEED (not fruit. Inés Bazán
Of course Dr. Grati, late December I think we have the results.

Wedneday November 4th, 2009;
Photos taked and uploaded today: beginning the "gross" harvest this week, only dry fruit pick-uped.
Best compliments for the harvest! Could you give us an estimation of production per hectare when finished? Best regards,
Photos uploaded September 8th:
Jatropha plantation at Tecomán, 174 dat. First ripen capsules.
Very impresive pictures. Density is high, plants are healthy. Looks like you have given an effort to suply enouhg water in dry season. Congratulations.
Your number of branches seems quite low. Do you think of pruning. How many branches do you expect in 1 plant?
And what is your expectation of seeds per ha? Do you think of extracting the oil? If yes, with wich extraction machines.
Did you do any economic fesibility study? If yes, for which price do ou produce the Jatropha oil?
Mr. Henning,
This first plot is just to known the "agronomic feasibility" under our conditions.
Yes, I think that after we concluded the first harvest we will prune to generate more branches (how many you think we can obtain from any stem?).
About expected yield: with an average of 8 bearing stems per plant, each branch have at the "first end" 12 to 16 fruits (sometimes even 28) then it bifurcate and each of the two "new ends" shown 9 to 12 fruits, at the 30% of the cases a second bifurcation is obtained and is not so rare than a third bifurcation is generated. We have 2,857 plants per hectare, with this information, might you help me to calculate an expected yield?
The economic feasibility is not yet considered, like the oil extraction.
Warmest regards,

Today I uploaded pictures showing the insects that we can find on jatropha flowers at our plantation.

Today, 19/07/2009 (122 dat), I uploaded a picture showing the first inflorescences at our plantation, and also one photo with the first fruit cluster that we could find.

Best compliments for new pictures!! Federico Maria Grati
We have 2 ha. in Veracruz we will like to share experience. Congratulations for your project.
Your experience is very interesting, and thank you for declearing the correct number of hectares you have planted. It is very rare for Jatropha farmers and i do appreciate very much. Can you please tell us: 1) the date of tranplanting? 2) irrigation by drip.
In similar conditions, we provide about 4 liters per plant every two days during the dry season. Federico Maria Grati
Dr. Grati,
The first nursery sowing was doing on December 19th 2008, subsequents sowings on December 26th and January 6th and 8th. The wednesday March 18th 2009 (the day that the Mexicans celebrate the 71th Anniversary of the petroleum-oil industry expropiation) we planted 2.3 ha, the rest 0.2 ha was planted on April 4th (33 days after). Today the plantation have 80 DAT.
About the irrigation, we use a 5/8 inch PE hose with drippers each 45 cm that supply 2.27 Lph at a 18 psi nominal pressure. I really don't have an irrigation record, but this week we apply three 2-hour, two 3-hour and one 6-hour shifts (I don't know if this is the correct word in English), the previous figures means (with the pressure fit) 11 Liters per plant per day, twice the water supply on the three or four previous weeks. For us the water is NOT a bounding.
I expect to have solved your questions, thanks for your interest.

Study very carefully for jatropha plantation.
the yield is relatively very low and unsecured/inconsisting yield.
To plant Jatropha as the energy crop will need the big and massive plantation to generate enogh/significant feed stock for BDF production.
Make sure that you did understand properly the nature of this eenrgy crop.
