Maize-Soybean-Cowpea Sequential Cropping as a Sustainable Crop Production for Acid-Infertile Clay Soils in Indonesia

Control of Soybean Nodule Formation by a Crack Fertilization Technique

“…The soil in Nagakute, light clay, became quite hard during mid summer without rainfall. Hard and/or compacted soil, often creates a complex soil physical environment (Iijima and Kato, 2007), and therefore, it usually restrains the root extension growth (Izumi et al, 2004a(Izumi et al, , 2004b. Under the complex stress environment, water and nutrient uptake characteristics will be quite different from the favourable soil condition Izumi et al, 2009).…”

Productivity, Weed Dynamics, Nutrient Mining, and Monetary Advantage of Maize-Legume Intercropping in the Eastern Himalayan Region of India

“…The choice of crop and row combinations or densities of companion crops is critical for the achievement of high yield and income in intercropping because they offer inter and intra-specific competition (Saka et al, 1993). Studies on the effect of relative component proportions on yield performance of maize-based intercropping have been conducted elsewhere by several researchers (Subasinghe and Senaratne, 2000;Polthanee and Trelo-ges, 2003;Izumi et al, 2004;Rusinamhodzi et al, 2012). However, such information is very limited in the eastern Himalayan region of India.…”

No-Tillage Enhanced the Dependence on Surface Irrigation Water in Wheat and Soybean

“…No-tillage is an effective sustainable cropping system to prevent soil erosion (Iijima et al, 1999(Iijima et al, , 2003(Iijima et al, , 2004Izumi et al, 2004b), and to reduce the production costs through reduced labor and machinery usage for the tillage practice. Although no-tillage is advantageous for crop production, it often affects crop root development due to the higher mechanical impedance to root elongation (Izumi et al, 2004a, b), and causes yield reduction under unfavorable conditions, such as drought.…”
