Steganography is the art and science of hiding or embedding data in a transmission medium. The goal of steganography is to hide an information message inside a harmless cover medium in such a way that it is not possible even to detect that there is a secret message. In this paper, the object oriented steganography is based on biometrics. Data is embedded into some regions of the skin and not to...

Excessive nitrogen (N) fertilization, low use efficiency, and heavy pollution are the dominant issues that exist in intensively cultivated double rice cropping systems China. Two-year field 15N microregion experiments were conducted to evaluate N fate a soil-rice system under series of different rate treatments from 2020 2021. The economic application simultaneously improved yield efficiency ro...

NDVI obtained from satellite at the pixel over the area of crop cultivation would represent a specific temporal profile, which could be discriminated from that of other land use. In this study, the author attempted to estimate the acreage of winter wheat sown area using multitemporal NDVI obtained from NOAA-AVHRR data. The study site was selected in the Huang-Huai-Hai plain in China, where the ...

Residue management in cropping systems is useful to improve soil quality. However, the studies on the effects of residue management on the enzyme activities and microbial community of soils in South China are few. Therefore, the effects of incorporating winter cover crop residue with a double-cropping rice (Oryza sativa L.) system on soil enzyme activities and microbial community in Southern Ch...

Accurate crop rotation information is essential for understanding food supply, cropland management, and resource allocation, especially in the context of China’s basic situation “small farmers a big country”. However, mapping smallholder agriculture systems remains challenging due to diversity types, complex cropping practices, fragmented cropland. This research established sub-seasonal identif...

The crops that we grow for food need specific climatic conditions to show better performance in view of economic yield. A changing climate could have both beneficial and harmful effects on crops. Keeping the above view in mind, this study is undertaken to investigate the impacts of climate change (viz. changes in maximum temperature, minimum temperature, rainfall, humidity and sunshine) on the ...

Despite being one of the most pro®table crops for the southeastern USA, cotton (Gossypium hirsutum L.) is considered to create a greater soil erosion hazard than other annual crops such as corn (Zea mays L.) and soybeans (Glycine max (L.) Merr.). Reduced tillage systems and cover cropping can reduce soil erosion and leaching of nutrients into ground water. The objectives of this study, which wa...

Paddy rice cropping systems play a vital role in food security, water use, gas emission estimates, and grain yield prediction. Due to alterations the labor structure high cost of paddy planting, (single or double rice) have drastically changed China recent years; many double-cropping fields been converted single-cropping other crops, especially southern China. Few maps detect single intensity f...
