Capsicum species are very important in Brazil because of economic, cultural and biological factors, and the country is considered to be a diversity center for this genus. Collection and maintenance of the genetic diversity in Capsicum are important to avoid genetic erosion. Besides the identification of species, the characterization and evaluation of accessions maintained in gene banks are of f...

Nitrogen (N) is a vital component of crop production. Wheat yield varies significantly under different soil available N. Knowing how wheat responds to or interacts with N produce grains essential in the selection use efficient cultivars. We assessed this study variations among genotypes for productivity-related traits three cropping systems (CS), high-nitrogen fungicide (HN-WF), without (HN-NF)...

Nitrogen fertilizer and planting density are key factors affecting rice yield nitrogen utilization efficiency. There is still a need to optimize management for high yield. We studied the effects of different quantities application (N0 0 kg ha−1, N1 120 N2 180 ha−1) (low-density: 18.8 hills m−2; high-density: 37.5 m−2) on yield, photosynthetic characteristics, antioxidant system, use ANOVA resul...

Plants have direct and indirect constitutively produced and inducible defenses against herbivores and pathogens, which can substantially aid in their ability to defend themselves. However, very little is known about the influence of agronomic factors on such defenses. Here, we tested the effects of nitrogen levels and water availability on the ability of cotton plants to deter feeding by Spodop...

Nitrogen responsiveness of three-finger millet genotypes (differing in their seed coat colour) PRM-1 (brown), PRM-701 (golden), and PRM-801 (white) grown under different nitrogen doses was determined by analyzing the growth, yield parameters and activities of nitrate reductase (NR), glutamine synthetase (GS), glutamate synthase; GOGAT, and glutamate dehydrogenase (GDH) at different developmenta...
