Crop cultivars now being grown in no-till production systems were developed by selecting for performance in conventionally tilled environments. In order to maximize production of corn (Zea mays L.), cotton (Gossypium barbadense L.), and soybean [Glycine max (L.) Merr.] in a no-till environment, it may be necessary to select for performance under the same conditions. The economic incentive for d...

Strawberry is a very popular fruit, appreciated for its unique flavor and many beneficial traits such as antioxidants useful amino acids, which strongly contribute to the overall quality of product. Indeed, fresh fruit fundamental aspect consumers, it crucial success breeding activities well enhancing competitiveness profitability industry. Nowadays, entire supply chain requires simple fast sys...

Action thresholds are traditionally based on the density of pests and the economic damage they cause to crops. Pest damage assessments are usually made in a "sterile" environment, devoid of extenuating factors such as predators, parasitoids, and alternative food sources. Recently, the effects of a predator or parasitoid species have been considered. However, interactions between natural enemy s...

the use of vermicompost and fall fertilization in soilless culture on strawberry cv. camarosa quality characteristics was evaluated in a factorial based on completely randomized design pot experiment with 5 replicates. experimental treatments were four chemical fertilization timings (no fertilizer, using fertilizer at fall, spring, fall + spring) and three levels of vermicompost (10, 20 and 40%...

the strawberry spider mite (ssm), tetranychus turkestani ugarov & nikolski, is an important pest of greenhouse cucumber in tropical and temperate regions of the world. the use of the host plant resistance is a basic method to reduce pesticide application in greenhouses. in this study, the biological responses of ssm to six greenhouse cucumber cultivars (puia, hedieh, milad ghadim, milad jad...

The growth and development of three strawberry cultivars commonly grown in a plasticulture system were documented. Strawberry plants were harvested monthly and divided by roots, crown, leaves, flowers, and fruit and then dried in an oven. The dry matter production and resource allocation proceeded along a predictable pattern of development. The establishment phase was characterized by an active...

High biodiversity is known to increase many ecosystem functions, but studies investigating biodiversity effects have more rarely looked at multi-trophic interactions. We studied a tri-trophic system composed of Centaurea jacea (brown knapweed), its flower head-infesting tephritid fruit flies and their hymenopteran parasitoids, in a grassland biodiversity experiment. We aimed to disentangle the ...
