Understanding greenhouse gases (GHG) emissions is becoming increasingly important with the climate change. Most previous studies have focused on the assessment of soil organic carbon (SOC) sequestration potential and GHG emissions from agriculture. However, specific experiments assessing tillage impacts on GHG emission from double-cropped paddy fields in Southern China are relatively scarce. Th...
Multiple cropping, a common practice of intensive agriculture that grows crops multiple times in the agricultural land in one growing season, is an effective way to fulfill the food demand given limited cropland areas. Deriving cropping cycles from satellite data provides the spatial distribution of cropping intensities that allows for monitoring of the multiple cropping activities over large a...
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...
corn–soybean cropping systems predominate. The effect of these cropping systems on indicators of soil quality Understanding long-term management effects on soil properties is only partially understood. Soil organic C has been is necessary to determine the relative sustainability of cropping systems. Soil physical, chemical, and biological properties were measured shown to increase in monocultur...
Intercropping is a sustainable practice to achieve higher production with the aim to limit external inputs. A field experiment was conducted at the research farm of the Faculty of Agriculture, University of Maragheh, Maragheh, Iran, during 2016 growing seasons with ten treatments to evaluate the yield, analyze the competition and insect’s assemblages in sunflower (as main plant)/soybean (as com...
Wheat (Triticum aestivum L.) variety mixtures represent a relatively unexplored avenue for maintaining yield and improving flour quality. A field experiment was conducted to examine the responses of three spring wheat varieties in pure variety and in variety mixtures under continuous cropping in Northeast China. Three modern spring wheat varieties, along with a three-variety mixture and a t...
A field trial with different sowing windows of the maize crop was done in Eastern Block Farm Tamil Nadu Agricultural University, Coimbatore, Nadu, India. The were scheduled mid every month for four seasons. treatments Kharif (2019) – June 15th, July and August 15th; Rabi (2019-2020) September October November Late (2020-2021) December January February Summer (2021) March April May 15th. agromet...
The use of cover cropping, as one element in a continuous living approach, has the potential to protect water quality and promote soil health, but overall U.S. acreage crops well adoption rates remain low. Research on behavioral barriers crop indicates lack information about locally suitable practices varieties, additional management complexity cropping high degree uncertainty outcomes, especia...
Determination of optimum sowing date plays an important role in crop management and achieving the higher yield. To study the effectof sowing date on seed yield of canola cultivars, a filed experiment was carried out as strip split plot block arrangement in randomized completed block design with three replications in 2017-18 and 2018-19 cropping seasons at Safiabad Agricultural and Natural Resou...
In order to evaluate the intercropping of barley-faba bean and choose the best planting pattern a field experiment was conducted in the growing seasons of 2015-2016 using a randomized complete block design with 8 treatments and 3 replications in Ramhormoz Khuzestan, Iran. The treatments were barley sole cropping with 20 cm spacing between rows, faba bean sole cropping with 40 cm spacing between...
