Detasseling is the operation that consists of removing the tassels of the female plants prior to silk emergence CERES-Maize, which was designed for simulation of hybrid maize and pollen shed to prevent self-pollination. During this (Zea mays L.), cannot be applied directly to seed-producing inbred maize because of specific field operations and physiological traits of operation, several leaves a...

Achieving optimal balance between maize yield and water use efficiency is an important challenge for irrigation production in arid areas. In this study, we conducted experiment Xinjiang China 2016 2017 to quantify the response of plant density schedules. The treatments included four levels: 360 (W1), 480 (W2), 600 (W3), 720 mm (W4), five densities: 7.5 (D1), 9.0 (D2), 10.5 (D3), 12.0 (D4), 13.5...

Drought and low nitrogen are major stresses for maize (Zea mays L.), populations from the Sahara Desert potential sources of stress tolerance. The objectives were to assess tolerance varietal heterosis effects Algerian under no-nitrogen fertilization water stress. A diallel among six population was evaluated drought (300 mm irrigation) vs. control (600 mm) 120 kh ha?1 N fertilization. Genotypes...

The Guanzhong region is a typical and important grain-producing area in China. effect of accumulated temperature rainfall on maize production the face global warming. Here, we collected meteorological data from six test sites to study climate change 1972 2018 this area. A two-year was conducted at multiple experimental analyze climatic factors yield disease region. In past 40 years, average tem...

Abstract Phosphorus and nitrogen nutrition have profound complicated innate connections; however, underlying molecular mechanisms are mostly elusive. PHR1 is a master phosphate signaling component, whether it directly functions in phosphorus–nitrogen crosstalk remains particularly interesting question. In maize, limitation caused tip kernel abortion ear shortening. By contrast, moderately low t...

In the field of precision agriculture research, it is very important to monitor crop growth in time so as effectively conduct diagnosis and management accurately predict yield quality. this experiment, relationship between vegetation index Zhengdan 958 Suyu 41 their quality when reducing N application (25 50% reduction compared local conventional rate) under low, medium high planting densities ...

Abstract The presented research aimed to confirm that the differences in lipid peroxidation of three maize ( Zea mays L.) hybrids with different genotypes and maturity are due nitrogen levels, which was observed based on amount malondialdehyde (MDA) measured leaves at main phenological stages plants. experiments were performed a multi-factorial long term fertilisation field trial. In study, pho...
