High-yield irrigated maize in the Western U.S. Corn Belt: I. On-farm yield, yield potential, and impact of agronomic practices
Quantifying the exploitable gap between average farmer yields and yield potential (YP) is essential to prioritize research and formulate policies for food security at national and international levels. While irrigated maize accounts for 58% of total annual maize production in the Western U.S. Corn Belt, current yield gap in these systems has not been quantified. Our objectives were to quantify ...

این مطالعه در سال 1386-87 در آزمایشگاه و مزرعه پژوهشی دانشگاه صنعتی اصفهان به منظور تعیین مناسب ترین تیمار بذری و ارزیابی اثر پرایمینگ بر روی سه رقم گلرنگ تحت سه رژیم آبیاری انجام گرفت. برخی از مطالعات اثرات سودمند پرایمینگ بذر را بر روی گیاهان مختلف بررسی کرده اند اما در حال حاضر اطلاعات کمی در مورد خصوصیات مربوط به جوانه زنی، مراحل نموی، عملکرد و خصوصیات کمی و کیفی بذور تیمار شده ژنوتیپ های م...
Yield potential and resource-use efficiency of maize systems in the western U.S. Corn Belt
Unlike the Central and Eastern U.S. Corn Belt where maize is grown almost entirely under rainfed conditions, maize in the Western Corn Belt is produced under both irrigated (3.2 million ha) and rainfed maize (4.1 million ha) conditions. Simulation modelling, regression, and boundary-function analysis were used to assess constraints to maize productivity in the Western Corn Belt. Aboveground bio...
متن کاملHigh-yield irrigated maize in the Western U.S. Corn Belt: II. Irrigation management and crop water productivity
Appropriate benchmarks for water productivity (WP), defined here as the amount of grain yield produced per unit of water supply, are needed to help identify and diagnose inefficiencies in crop production and water management in irrigated systems. Such analysis is lacking for maize in the Western U.S. Corn Belt where irrigated production represents 58% of total maize output. The objective of thi...
متن کاملEffect of Agronomic Practices on Growth, Grain Yield, Malt Yield Losses of Barley (Hordeum vulgare L.)
A field experiment was conducted during 2006-07 and 2007-08 at Ludhiana to study the effect of different agronomic practices on growth, grain yield, malt yield and losses of malt barley (Hordeum vulgare L.).The study revealed that plant height, dry matter accumulation, grain and straw yield were statistically at par with different method of sowing during both the years. Similar trend was also o...
