Yield and Yield Components of Sorghum and Soybeans of Varying Plant Heights when Intercropped
1984
Elmore, R. W. | Jackobs, J. A.
A 2-year field study was conducted to examine the effects of different sorghum (Sorghum bicolor L. Moench) plant heights on yield and yield components of both sorghum and soybeans (Glycine max L. Merr.) and to compare production of intercrop and monoculture cropping systems. In 1977, ‘Amsoy 71’ soybeans were planted with a short (1.2 m) and a tall (1.6 m) sorghum cultivar in alternate 0.38 m rows on a Drummer silty clay loam (Mollisol, fine-silty, mixed, mesic Typic Haplaquoll). In 1978, two short (1.3 m) and two tall (1.6 m) sorghum cultivars were intercropped with four soybean cultivars in 0.4 and 0.8 m rows on a Coto clay (Oxisol, clayey, kaolinitic, isohyperthermic Tropeptic Haplorthox). Soybean yields with tall sorghum were 71 and 18% less than those with short sorghum for 1977 and 1978, respectively. These reductions were due to fewer pods/plant in both years, fewer seeds/pod in 1978, and decreased seed weight in 1977. Narrow rows increased soybean yields 50% with short sorghum and by 35% with tall sorghum in 1978. Intercrop tall sorghum yields were greater than short sorghum yields by 86% in 1977 and 74% in 1978. All yield components except plants/ha contributed to the increase in 1978. Intercrop soybean yields were 37 and 69% of monoculture yields in 1977 and 1978, respectively. Intercrop sorghum yields were 40 and 45% of monoculture yields in 1977 and 1978, respectively. Land equivalent ratios were not different in 1977, but in 1978 they were greater with tall sorghum than with short sorghum, 1.17 vs 1.10, and were greater in intercrop than in monoculture, 1.14 vs 1.00.

Physical Environment of Sorghum- and Millet-growing Areas in South Asia
1984
Sivakumar, M V K | Huda, A K S | Virmani, S M
In the semi-arid areas of Asia, rainfed farming of sorghum and millet constitutes the main pattern of land use. About 57% of the world's millet and 38% of the sorghum come from Asia; South Asia contributes 60% of the total Asian production of both crops, with India alone producing 96% of the millet and 98% of the sorghum. However, a major constraint to increasing production is drought, resulting from low and variable rainfall and soils with low water-holding capacity. The wide range of variation in other climatic parameters as well—temperature; radiation, and evapotranspiration—in the sorghum- and millet-growing areas is illustrated and discussed. The broad soil regions in semi-arid Asia are described, and measures suggested for improving and stabilizing yields by matching the crop growth cycle with the growing period. The variability in the phenology, growth, and yield of sorghum is illustrated with examples from a 3-year multilocation sorghum-modeling experiment. It is proposed that data banks be set up to collect—via an interagency network—the information on climate, soils, and crops needed to assess the impact of the physical environment on sorghum and millet production in the semi-arid tropics.

Extract: An econometric model, measuring the impact of market forces and Government policies on demand and prices for U.S. sorghum during 1959/81, is estimated. The model shows that domestic feed demand is less responsive to a price change than is export demand. Corn's substitution for sorghum as a feed has further eroded the sorghum market. Today's sorghum industry faces surplus conditions similar to those of the sixties. Simulation with the model indicates earnings will be weak unless Government programs change or carryover stocks are drawn down.
