The Burmans arrived in the hot plains of upper Burma in approximately 832 AD (Luce 1985 101 103) and would have adopted some lowland crops while abandoning upland crops not suitable for the new environment.
Recently released and high yielder cultivars of peanut (Werer-924 and Sedi) were obtained from lowland oil crop, Haramaya University, Ethiopia.
The main crops grown are maize and millet and also some lowland cash crops.
In the Orinoco lowlands, the crop was successful because during the growth period it tolerates seasonal rainless conditions and makes efficient use of water with high CAM activity.
For the lowland, the cropping systems are wet season rice followed by dry season rice or water melon, peanut, mungbean, sweet corn, taro etc. Rubber-based cropping systems, can be widely seen in upland area in the rainy season.
With respect to increasing the production of 'own' cereal crops, lowland grazing livestock farmers are the group most likely to undertake this option.
Rice is restricted to lowlands, due to crop climate requirements, and is found mostly in municipalities with larger fraction of agricultural lands.
On the other hand, in the lowland terai three crops per year are common where the water supply is adequate.
In the colonial era copra was the premier crop in lowland areas, but now only small amounts are produced, together with some rubber in the southern region.
Thus, a three-year field experiment was conducted in Brazil on a lowland Plinthaquults to investigate crop performance, water input productivity (WPin) and N recovery under five irrigation regimes: continuous flooding (CF); AWD with short cycle (AWDS); AWD with long cycle (AWDL); saturated soil without ponded water (SS); and aerobic (AR).
