In conservation tillage systems, at least 30% of the soil surface was covered by crop residues which generally contain significant amounts of nitrogen (N). However, little is known about the multi-seasonal recoveries of the N derived from these crop residues in soil-crop systems, notably in northeastern China. In a temperate agro-ecosystem, 15N-labeled maize residue was applied to field surface...
Rice is one of the key food grains linked to the food security of the growing population of the world. India has largest rice area in the world and stands second in production. The rice crop is important both from the food security and climate change point of view. The present paper highlights rice-growing pattern in India derived using satellite remote sensing and Geographic Information System...
Continuous cropping of rice (Oryza sativa L.) and wheat (Triticum aestivum L.) deplete soil fertility and crop productivity. One strategy to increase crop productivity under rice-wheat system is balanced application of crop nutrients. Field experiment was conducted to assess the impact of phosphorus (0, 40, 80, 120 kg P ha(-1)) and zinc (0, 5, 10, 15 kg Zn ha(-1)) on the productivity of rice ge...
The study presents the preliminary results of two classification exercises assessing the capabilities of pre-operational (August 2015) Sentinel-2 (S2) data for mapping crop types and tree species. In the first case study, an S2 image was used to map six summer crop species in Lower Austria as well as winter crops/bare soil. Crop type maps are needed to account for crop-specific water use and fo...
Agronomic Characteristics Correlation of Sunflower Genotypes Grown in the Second Crop in the Cerrado
Soybean [Glycine max (L.) Merr.], with high oil and protein content, is one of the world's main nutritional sources millions hectares are given over to its cultivation. Intensive farming producing multiple crops per year (such as second-crop soybean cultivation), can improve natural resource exploitation productivity. The objective this study was examine effects some cultivars on yield componen...
