Batao in the upland. Cropping system


· Batao (Lablab purpureus) or hyacinth bean and com are planted simultaneously at the same hill at the stab of the rainy season.

· Plant population -- 53,333/ha for corn and 5,926/ha for batao

· Batao is planted in hills together with corn so that:

- they will not be damaged during inter-row cultivation;

- no com row is sacrificed for a batao row; and,

- batao can use corn as pole.

· Corn intercrop is managed in the same way as monocrop corn except during harvesting
Harvest only the corn ears. Leave the corn stover to serve as support for the batao.

· Corn stalk can support the batao until its flowering and pod formation. Batao bears more pods when propped than when allowed to grow prostrate on the ground

Batao plant


The first harvesting of green batao pods can start about three weeks after the corn harvest (grain). Harvest the green batao pod every week. There could be 5 to 6 primings or a total green pod harvest of about 2.5 t/ha

Allow the last priming to mature as seed source.


Fodder. After the harvest of pods, batao herbage can be used as fodder for cattle in summer when feeds are scarce.

Green manure. Allow batao to grow beyond the summer period to achieve rapid regrowth at the onset of the rainy season.

Before land preparation for the next crop, either chop the vines with a scythe right on the field or collect and chop them with a mechanical chopper. Vines can also be chopped manually using bolo and chopping board. Chop to a length of 15-20 cm so that it would not hamper the plowing operation.



Spread the chopped herbage on soil surface.

Incorporate the herbage by plowing.


Note: Other than batao, alternative legume species could also be used, such as winged bean (Psophocarpus tetragonalobus). However, it should be planted three weeks after sowing the corn.
