Substantial reproduction of Meloidogyne incognita on winter cover crops may lead to damaging populations in a subsequent cotton (Gossypium hirsutum) crop. The amount of population increase during the winter depends on soil temperature and the host status of the cover crop. Our objectives were to quantify M. incognita race 3 reproduction on rye (Secale cereale) and several leguminous cover crops...

to assess required growing degree days (gdd) for phenological stages of four clover species in different planting dates a field experiment was conducted in 2010-11 and 2011-12 cropping seasons in seed and plant improvement institute in karaj, iran. three planting dates (14 september, 28 september and 13 october) and six clover varieties were assigned to main plots and sub-plots, respectively, a...

In fall 2000, an on-farm sustainable agricultural research project was established for cotton, Gossypium hirsutum L., in Tift County, Georgia. The objective of our 2-yr research project was to determine the impact of several cover crops on pest and predator insects in cotton. The five cover crop treatments included 1) cereal rye, Secale cereale L., a standard grass cover crop; 2) crimson clover...

scince 1990 research on clover has been commenced in karaj and other field stations of seed and plant improvement institute, iran. one of the achievements of this initiative is selection, improvement and release of alborz 1 crimson clover cultivar. new crimson clover cultivar, alborz 1 was primarily selected from clover germplasm received from food and agriculture organization (fao), the united...

Experiments were focused on differences in the ripening of crimson clover (Trifoliumincarnatum L.) and red (Trifolium pratense influence pre-harvest treatment with desiccants. The drying leaves, stems heads during ripening, regrowing, breakdown yield parameters including seed compared. exhibited natural faster than clover. In clover, before harvest was 80 - 100%, 50– 95%, 100 %, respectively. 2...

Cover crops are important components of sustainable agricultural systems. They increase surface residue and aid in the reduction of soil erosion. They improve the structure and water-holding capacity of the soil and thus increase the effectiveness of applied N fertilizer. Legume cover crops such as hairy vetch and crimson clover fix nitrogen and contribute to the nitrogen requirements of subseq...
