Crop straw retention influenced crop yield and greenhouse gas emissions under various external conditions

Environmental Science and Pollution Research, 2021
Crop straw retention is a strongly recommended practice for sustainable agricultural production in China. However, a comprehensive analysis of straw retention effects on crop yield, N2O and CH4 emissions, net greenhouse gas (NGHG), and net greenhouse gas intensity (NGHGI) and their response to various external influence factors, including location ...

Energetics in Various Cropping Systems

International Journal of Pure & Applied Bioscience, 2018
Energy is one of the most valuable inputs in agriculture. It is being invested in various forms such as mechanical, chemical, electrical etc. The amount of energy used in agricultural production, processing and distribution should be significantly higher in order to feed the expanding population and to meet other social and economic goals.

SOIL ERODIBILITY PARAMETERS UNDER VARIOUS CROPPING SYSTEMS OF MAIZE

Hydrological Processes, 1996
For four years, runoff and soil loss from seven cropping systems of fodder maize have been measured on experimental plots under natural and simulated rainfall. Besides runoff and soil loss, several variables have also been measured, including rainfall kinetic energy, degree of slaking, surface roughness, aggregate stability, soil moisture content, crop

Optimizing edible fungal growth and biodegradation of inedible crop residues using various cropping methods

Bioresource Technology, 2008
Long-term manned space flights to Mars require the development of an advanced life support (ALS) ecosystem including efficient food crop production, processing and recycling waste products thereof. Using edible white rot fungi (EWRF) to achieve effective biomass transformation in ALS requires optimal and rapid biodegradative activity on lignocellulosic

Methane production through anaerobic digestion of various energy crops grown in sustainable crop rotations

Bioresource Technology, 2007
Biogas production is of major importance for the sustainable use of agrarian biomass as renewable energy source. Economic biogas production depends on high biogas yields. The project aimed at optimising anaerobic digestion of energy crops. The following aspects were investigated: suitability of different crop species and varieties, optimum time of ...

Food crop responses to various factors in Romania

AIP Conference Proceedings, 2020
Vegetables are a significant component of food strategies and an important source of vitamins through their content in mineral salts and their carbohydrate intake. In this paper are analyzed various factors that can affect the ability of certain vegetable crops from Romania to adapt to different conditions, including the climatic ones.
