Indian landmass with 1.45% of the world’s total geographical area accounts for approximately 2.7–5.5% to the global NPP estimates with agriculture contributing to more than sixty percent. This paper reports the spatio-temporal pattern of agricultural NPP in India using SPOT VGT 10-day composite NPP product for 2002-03 to 2004-05 agricultural years. Detailed analysis was carried out for the Indo...

Biotic and abiotic constraints seriously affect the productivity of agriculture worldwide. The broadly recognized benefits of legumes in cropping systems-biological nitrogen fixation, improving soil fertility and broadening cereal-based agro-ecologies, are desirable now more than ever. Legume production is affected by hostile environments, especially soil salinity and high temperatures (HTs). A...

The choice of variety for agricultural systems with multiple crops may differ from the one used in sole crop because of the changes in environmental conditions brought about by interspecific plant competition. Information about varietal performance under living mulch conditions as well as the suitability of the results of the official variety testing, conducted under conventional cropping condi...

Producers are frequently most interested in economic comparisons of various cropping systems. We compared continuous corn (Zea mays L.) and continuous soybean [Glycine max (L.) Merr.] with 2-, 3-, and 5-year rotations, the latter two including wheat (Triticum aestivum L.) and alfalfa (Medicago sativa L.), using either chisel plow or no-tillage practices. Crop yield and returns to land and manag...

A limited irrigation study involving four cropping systems and evaluating crop rotations was initiated at the Southwest Research-Extension Center near Tribune, KS, in 2012. The were two annual (continuous corn continuous grain sorghum) 2-year (corn-grain sorghum corn-winter wheat). In 2020, yields similar for all rotations, although averaged across past 8 years, greater following wheat than cor...

Wheat is the most widely cultivated food crop in the world, which provides nutrition to most of the world population and is well adapted to a wide range of environmental conditions. Timely and efficient rates of nitrogen (N) application are vital for increasing wheat grain yield and protein content, and maintaining environmental sustainability. The goal of this study was to investigate the effe...

A large part of the Indo-Gangetic plain has marginal soils, which are depleted of nutrients and sandy with low water-holding capacity. Fertilizers and irrigation are applied to obtain regular yield. However, high usage of fertilizers and inappropriate methods of irrigation lead to a degradation of soil microfl ora and loss of soil fertility in the long term. In close collaboration with other pa...

Fusarium head blight (FHB) is a multifaceted disease caused by some species of Fusarium spp. A huge production of mycotoxins, mostly trichothecenes, often accompanied this disease. Amongst these toxic compounds, deoxynivalenol (DON) and its derivatives represent a major issue for human as well as for animal health and farming. Common and durum wheat are amongst the hosts of trichothecene-produc...
