Autotoxins in Continuous Tobacco Cropping Soils and Their Management

open access: yesFrontiers in Plant Science, 2023
Tobacco belongs to the family Solanaceae, which easily forms continuous cropping obstacles. Continuous cropping exacerbates the accumulation of autotoxins in tobacco rhizospheric soil, affects the normal metabolism and growth of plants, changes soil microecology, and severely reduces the yield and quality of tobacco.

Biological Control of Melon Continuous Cropping Obstacles: Weakening the Negative Effects of the Vicious Cycle in Continuous Cropping Soil.

open access: yesMicrobiology Spectrum, 2022
The soil environment, crop growth and fruit quality of melons are negatively affected by long-term continuous cropping. It is important to study the mechanism of continuous cropping obstacles and their biological control.

Effects of continuous cucumber cropping on crop quality and soil fungal community

Environmental Monitoring and Assessment, 2021
Long-term continuous cropping is a common practice in facility vegetable production, which has an adverse effect on cucumber yield and quality. Soil fungi are of great significance for creating a normal soil ecological environment. However, the impact of continuous cropping on cucumber quality and soil fungal community has yet to be understood. In this

The Carbon Crop: Continued

Science, 1997
With regard to the relentlessly positive article by Anne Simon Moffat about forests as carbon sinks (Research News, [18 July, p. 315][1]), it is worth noting several points, the most critical being the importance of differentiating between harvesting a forest stand for biomass energy and doing ...

Natural Variation in Crops: Realized Understanding, Continuing Promise

Annual Review of Plant Biology, 2021
Crops feed the world's population and shape human civilization. The improvement of crop productivity has been ongoing for almost 10,000 years and has evolved from an experience-based to a knowledge-driven practice over the past three decades. Natural alleles and their reshuffling are long-standing genetic changes that affect how crops respond to ...

Nitrogen Fertilization of Palmarosa in Continuous Cropping

Journal of Herbs, Spices & Medicinal Plants, 1997
ABSTRACT A field experiment with palmarosa (Cymbopogon martinii) conducted from 1989 to 1991, in Lucknow, India, indicated that the application of 100 kg/ha nitrogen maximized herb and essential oil yields (27.6 metric tons of herb/ha and 123.5 kg of oil/ha) in the first year of cultivation.

Continuous cropping systems and weed selection

Euphytica, 2006
Changes in the weed flora of agro-ecosystems can occur as long-term changes or temporary fluctuations in species composition. The rate at which weed population shifts occur depends on the selection pressure imposed, genetic variability among weed populations, plant characteristics and environmental factors.
