Two varieties of Jatropha curcas occur naturally:<\/strong>
– conventional non-edible jatropha plants and
– a phenotypically similar, but edible variety called Xuta, which lacks compounds called phorbol esters present in the non-edible varieties.
Traditional uses: fence plant around small farms, medicinal purpose, edible variety (called Xuta in Mexico) used as human food in Mexico
Pollination is by insects, usually honey bees
The Jatropha plant, even the edible variety, is non-edible to grazing animals, but honey produced from it is edible
Conventional, non-edible Jatropha plants are familiar backyard and fence plants in many countries and people are familiar with it and its non-edible nature.<\/p>\n

Jatropha plantation products<\/h5>\n
Pruned biomass:<\/h5>\n

to keep the plants at a height of about 2m, pruning would be required every year. Depending on plant nature and size between 1.5 and 5kg dry matter would be generated from 1 plant through pruning<\/p>\n

Jatropha fruit fractions:<\/h5>\n

the major production item from the jatropha plantation are the fruits. They yield the following fractions on processing.[\/et_pb_text][\/et_pb_column][\/et_pb_row][et_pb_row column_structure=”1_3,1_3,1_3″ _builder_version=”4.23.4″ _module_preset=”default” global_colors_info=”{}”][et_pb_column type=”1_3″ _builder_version=”4.23.4″ _module_preset=”default” global_colors_info=”{}”][et_pb_blurb title=”Freshly harvested fruits” image=”https:\/\/www.webdemourl.com\/jatropower\/wp-content\/uploads\/2024\/11\/Freshly-harvested-fruits.webp” _builder_version=”4.23.4″ _module_preset=”default” header_text_align=”center” box_shadow_style=”preset1″ global_colors_info=”{}”][\/et_pb_blurb][\/et_pb_column][et_pb_column type=”1_3″ _builder_version=”4.23.4″ _module_preset=”default” global_colors_info=”{}”][et_pb_blurb title=”Dried fruits \u2013 3 days of sun drying” image=”https:\/\/www.webdemourl.com\/jatropower\/wp-content\/uploads\/2025\/06\/image-28.webp” _builder_version=”4.27.4″ _module_preset=”default” header_text_align=”center” box_shadow_style=”preset1″ locked=”off” global_colors_info=”{}”][\/et_pb_blurb][\/et_pb_column][et_pb_column type=”1_3″ _builder_version=”4.23.4″ _module_preset=”default” global_colors_info=”{}”][et_pb_blurb title=”Fruit Husks” image=”https:\/\/www.webdemourl.com\/jatropower\/wp-content\/uploads\/2024\/11\/Fruit-Husks.webp” _builder_version=”4.23.4″ _module_preset=”default” header_text_align=”center” box_shadow_style=”preset1″ locked=”off” global_colors_info=”{}”][\/et_pb_blurb][\/et_pb_column][\/et_pb_row][\/et_pb_section][et_pb_section fb_built=”1″ _builder_version=”4.23.4″ _module_preset=”default” background_color=”rgba(68,88,14,0)” global_colors_info=”{}”][et_pb_row _builder_version=”4.23.4″ _module_preset=”default” width=”89%” width_tablet=”89%” width_phone=”89%” width_last_edited=”on|desktop” max_width=”1622px” max_width_tablet=”1622px” max_width_phone=”1622px” max_width_last_edited=”on|desktop” global_colors_info=”{}”][et_pb_column type=”4_4″ _builder_version=”4.23.4″ _module_preset=”default” global_colors_info=”{}”][et_pb_text _builder_version=”4.23.4″ _module_preset=”default” global_colors_info=”{}”]<\/p>\n

The fruits can be mechanically shelled using simple locally made machinery. Both fresh and dried fruits can be de-husked. The wet husk is ideal for mulching the plantation. For dry fruits mulch forms about 40% w\/w. Dry husk has an energy content of 14MJ per kg and can be used as burning fuel.<\/p>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n
