The highest yield, averaged 13.86 Mg ha −1, was observed for HY during all three experimental years and then 11.11 Mg ha −1 for OPT-2. Though a ban on maize imports could accelerate Nigeria’s adoption of genetically modified (GM) TELA maize, it may be two years before the insect-resistant variety is approved, creating severe hardships for the country’s poultry industry in the meantime. However, such agronomic practices under changing climatic condition is not adequate to enhance crop production as the changing climatic conditions are reported to negatively affect crop growth, yield, soil quality and thereby the nutritional quality of agricultural produce. Maize is a major staple food crop grown in diverse agro-ecological zones and farming systems, ... agronomic management), markets and institutions to advance the case for sorghum and millets in the ... good agricultural practices (GAP) to close yield gaps, improving quality management along In this article, you will find the classification of crop plants in agriculture based on agronomic classification.

Therefore, the objectives of this study are to 1) determine maize yield gaps caused by soil physical properties, of crop at .Its proper time'. The large yield gap was attributed mainly to greater dry matter (DM) and N accumulation with IAP than with FP owing to increased leaf area index (LAI) and DM accumulation rate, which were promoted by greater soil mineral N content (Nmin) and root length. In addition, more information is needed on the impact of fall armyworm on maize yield in Africa, as previous studies have focused on data trials or farmer questionnaires rather than using data from farmer fields. Maize does not tolerate waterlogging, so good drain… Maize with a high percentage of translucent of hard endosperm is preferred by the dry milling industry, because it produces more of the popular high-quality and high-value products sought after than does soft maize. The use of improper maize agronomic practices could contribute to maize yield gaps. Integrated agronomic practice increases maize grain yield and nitrogen use efficiency under various soil fertility conditions, mineral N content (ammonium N and nitrate N). Yield.

Is the only cereal, which Identifying the agronomic optimal plant density (AOPD) for maximum grain yield is essential to develop enhanced management strategies for maize (Zea mays L.) production.In this study, we used a boundary‐line method to examine the yield response of maize to plant density in China, based on the metadata (2783 data points) gathered from 157 recent studies during 2000–2017. 9 March 2009 21 September 2008 by klopez. increased in these areas if the optimal agronomic practices were applied. The use of improper maize agronomic practices could contribute to maize yield gaps. Because of greater grain yield and N uptake, IAP significantly increased N partial factor productivity, agronomic N efficiency, N recovery efficiency, and physiological efficiency of applied N compared to FP, particularly in the HSF fields. The APS were conducted by EIAR in 3 to 4 grids…, Growth, Yield-Related Traits and Yield of Lowland Maize (Zea mays L.) Varieties as Influenced by Inorganic NPS and N Fertilizer Rates at Babile, Eastern Ethiopia. Therefore, it is important to quantify the impacts of agronomic factors, including soil physical properties, cultivar selections, and management practices on yield gaps of maize under the changing climate in NEC in order to provide reliable recommendations to narrow down the yield gaps. maize are: (1) that cultivated maize originated from papyrescent corn, a type superficially resembling a weak form of pod corn; (2) that maize is an allopolyp1oid hybrid originating in South-East Asia by the hybridization of two ten-chromosome species such as Coix and So~hum. The survey was conducted using 100 households. 6.1.2 Check moisture content of maize … Agronomic management practices had significant effects on maize yield over the 2009–2011 study period.

Jeff Coulter, University of Minnesota (U of M) Extension corn agronomist, shares this list of four agronomic practices and his latest research and thoughts about yields and payoff. Maize (Zea mays L.) productivity has increased globally as a result of improved genetics and agronomic practices.Plant population and row spacing are two key agronomic factors known to have a strong influence on maize grain yield. The highest yield, averaged 13.86 Mg ha −1, was observed for HY during all three experimental years and then 11.11 Mg ha −1 for OPT-2. The delay of the maize harvest may cause qualitative and quantitative grain losses. •The IPM strategy should take into account complex pest problem Sampling date Crop infestation (%) Stemborer FAW infestation (%) 6 WAP Maize 36.75 ± 2.41b 89.50 ± 1.53b Plant population has a strong influence on maize grain yield (Van Smallholder farmer productivity in developing countries is limited by diverse biophysical, political and socio-economic factors. Res., 2010, 48(1) 55 significant positive correlation (r = 0.6173) was observed between number of cobs per plant and grain yield (Table 2). 2014, the projected total global production of maize grain was 1037.8 Tg (FAO, 2017). Characteristics of maize cultivars in Africa: How modern are they and how many do smallholder farmers grow? Crop producers transitioning to an organic cropping system must grow crops organically without price premiums for 36 months before certification.
