One of the most significant yield losses in tomato ( Solanum lycopersicum L.) is due to weeds. Yellow and purple nutsedge, large crabgrass, Palmer amaranth are troublesome weed species production throughout southeastern United States. This study aimed determine impact soil steaming, plastic mulching, cover crops on suppression, height, fruit yield. The used were hairy vetch Vicia villosa ), cri...

Growing evidence has emerged that cover crops may be able to improve phosphorus (P) cycling and contribute the P nutrition of subsequent crop. This could particularly important in farming systems, with limited access inputs where low soil availability been identified. In a pot experiment using soils labelled radioactive 33P, we examined how range crop residues directly uptake ryegrass, as well ...

In annual forage legumes such as the common vetch (Vicia sativa L.), in which the pods represent a substantial proportion of the total biomass, the optimum harvesting stage may not adjust to the classical model of decreasing nutritive value after flowering. The effect of harvest time on the yield of the main chemical components of common vetch was evaluated under field conditions typical of the...

Nod factors secreted by Rhizobium leguminosarum bv. viciae induce root hair deformation, involving a reinitiation of tip growth, and the formation of nodule primordia in Vicia sativa (vetch). Ethylene is a potent inhibitor of cortical cell division, an effect that can be counteracted by applying silver ions (Ag+) or aminoethoxy-vinylglycine (AVG). In contrast to the inhibitory effect on cortica...

in order to adapt the results of previous researches on annual forage legumes in zanjan province to cold regions condition of iran, yield and quality characters of two outstanding species namely grass pea (lathyrus sativus l.) and common vetch (vicia sativa l.) were evaluated in summer fallow cultivation condition for one year in 28 locations over 11 provinces of the country. in the variance an...

Aim of study: To evaluate the performance beef calves fed black oat and Italian ryegrass pasture seeded with several different seeding rates (SR) common vetch in a crop-livestock integrated system.Area The experiment was carried out Dois Vizinhos city, Paraná, Brazil.Material methods: An area 8.3 ha used, which divided into 11 paddocks, 0.75 each. Nellore (n = 22), 7 ± 2 months old initial body...

Hairy vetch is a leguminous winter annual cover crop that provides a significant contribution toward meeting the nitrogen requirement of succeeding crops. Hairy vetch residue is capable of suppressing weeds, but low levels of residue can intermittently stimulate the emergence of weeds, particularly smooth pigweed. This research was conducted to assess the inhibitory and stimulatory effects of h...

Materials and methods Samples of A. pisum were collected from natural populations on vetch or white clover, preserved in acetone, and subjected to DNA extraction individually. At each locality, 20 aphids were subjected to specific PCR detection of the endosymbionts as described (S1). The aphid strain TUt, naturally infected with PAUS, was derived from a parthenogenetic female collected on white...

 Homand Absard Rangeland Research Station is located 70 km northeast of tehran and 15 km southeast of Damavand with an altitude of 1972 m a.s.l., an average annual rainfall of 333 mm,  and a cold semi-steppe climate. In order to compare  the seed production of Vicia villosa under different cultivation seasons and methods, the seeds were initially collected from natural habitats similar to the m...
