Multiple Cropping with Rice. I. Effects of Soil Moisture Levels on the Performance of Upland Crops II. Effects of Seeding Methods on the Performance of Mungo

(Lao PDR), Master of Science (University of the Philippines Los Baños)

Thesis Abstract:

Two seperate but related field experiments were conducted to test the premise that successful multiple cropping with rainfed rice depends on the rapid setting of good stand and satisfactory performance of the selected crop under increasing soil moisture stress.

One of the experiments was designed to determine the effects of different soil moisture regimes on the growth and performance of five upland crops, namely, sweet corn, songhum, soybean, mungo and sweet potato. The crops were grown on raised plotbeds with heavy clay soil under three soil moisture levels. Results showed that at low moisture stress could be used as a cristerion for crop selection in succession cropping with rainefd rice

The other experiment was designed to evaluate eight methods of seeding mungo after rice harvest. Results showed good stand establishment and crop performance with three seedling methods: broadcast after plowing and harrowing, row-seeded after plowing and harrowing, and furrow-seeded followed by harrowing. The last method, which involved the least operation, seemed to be the most practicable.
