Book Description
Sustainable-intensification (SI) is known as a strategy to enhance agriculture productivity, while minimizing negative impacts on the environment, and promoting social benefits. The SI concept broadened over the years to cover a wide range of agriculture systems and sustainability issues. Recently, literature reviews revealed that SI research has often failed to address all aspects of the SI concept, specifically social, economic and political dimensions. Influenced by previous SI literature, this dissertation presents original research for conducting interdisciplinary broad-scale SI research. A mixed-method approach influenced by Farming System Research was used, to determine whether modernized corn-soybean intercropping was a suitable SI cropping practice for the southeast Buenos Aires (SEBA) region of the Argentine Pampas. Corn-soybean intercropping was assessed through the incorporation of four studies that each differed in scale, scope and methodology.

Book Description
A study was conducted from November 1988 to July 1989 at the Central Experiment Station, University of the Philippines at Los Banos UUPLB) to: (a) determine the influence of row intercropping with different proportions of corn and soybean on growth and production performance of corn and soybean, (b) evaluate and compare the seed quality of corn and soybean in terms of physical, physiological quality and protein content when grown in intercropping and monoculture, and )c) determine the best proportional combination of corn and soybean as an alternative method of seed production. Growth performance but not seed quality of soybean was affected by intercrops. Lower population density in intercorps produced taller soybean plants longer time to maturity. With higherpopulation density in intercrops, yield of soybean on a per plant and per hectare basis was higher due to the higher number of nodes and pods per plant.Big seeds tended to have higher crude protein content than small seeds. Plant height, days to tasseling, silking and maturity of corn were significantly affected by population density in intercrops. Lower population density of corn in intercropping, produced plants of shorter statures but which took the longer to tassel, silk and mature; higher seed yield per plant due to the higher number of seeds per ear, but lower seed yield per hectare basis; and a tendency for higher proportion of big seeds. Big seeds of corn tended to have higher crude protein content, than small seeds. No other physical and (...).

Book Description
Fall-seeded cover crops are limited by the short growing season remaining between harvest and planting the succeeding crop. To address this challenge, we considered two alternative systems for introducing cover crops into corn (Zea mays L.)- soybean (Glycine max L.) cropping systems. The first alternative was to interseed the cover crops species with corn at specific developmental stages. We evaluated the effect on corn, cover crop biomass, and the subsequent soybean crop. No detrimental effects on corn were found when cover crops were interseeded at or after corn canopy closure due to the limited cover crop biomass produced during the growing season. However, corn was negatively affected with cover crops interseed at corn planting. Cover crops interseeded at canopy closure did not establish due to corn canopy shading. Cover crops interseeded at or after R5 (dent) produced greater biomass the following spring than in the fall, and cover crops interseeded at R5 and R6 (physiological maturity) produced greater biomass than cover crops interseeded at corn harvest. This indicated that the interseeding by broadcasting cover crops can be successful for improving biomass production. The second alternative was to modify corn management practices such as planting date, plant population, and comparative corn relative maturity (CRM) to allow earlier cover crop seeding dates. We attempted to understand the impact on corn yield, cover crop biomass production, and the subsequent soybean crop. Early- and early-to-medium-maturity hybrids allowed corn harvest about one month earlier and medium-maturity hybrids about 15 d earlier than late-maturity hybrids. No differences in corn yield were observed between the medium- and late-maturity hybrids planted at the earlier planting date, with a 107 CRM hybrid planted early having the highest yield of 16.0 Mg ha-1. The greatest cover crop biomass production occurred with the earliest cover crop planting date. Cover crop biomass increased with air temperature, which was measured with growing degree days (GDDC). This indicates that changes in planting date and corn CRM hybrids are important to increase the potential for use of cover crops. The subsequent soybean yield was not affected by cover crops in either alternative.
