No-tillage cultivation of crops on the sandy upland field in Northeast Thailand
Country
Thailand
Description
[Synopsis]
No-tillage cultivation of seed crops (maize, legumes, etc.) is a promising technique to develop a large scale production on the sandy soil in Northeast Thailand. No-tillage seeding alleviated busy and laborious odd jobs for land preparation at the beginning of rainy season, and prevented soil erosion which was commonly observed after the tillage of fields. It was also effective to preserve soil moisture in dry season due to the undisturbed soil condition. The growth of crops in no-tillage was generally superior to that in tillage seeding. In rainy season, crust formation on the soil surface inhibited the growth in tillage seeding. The higher soil moisture in no-tillage contributed to a vigorous growth in dry season. A no-tillage seeder with rotary disk and drill seeder was manufactured and tested for applicability, which worked Satisfactorily on the sandy soil performing accurate grooving and seeding.
