Soil compaction has a real effect on rice growth in the Mekong Delta. The correlation between soil and (tiller number plant height) paddy field An Giang province was evaluated 2020 Winter-Spring Summer-Autumn crops using Pearson's test. research results show that 0-20 cm from surface positive with tiller number, while height is non-significant. Therefore, prediction model for numbers constructe...

In herbivorous insects, host plant switching is commonly observed and plays an important role in their annual life cycle. However, much remains to be learned about seasonal host switching of various pestiferous arthropods under natural conditions. From 2006 until 2012, we assessed Apolygus lucorum (Meyer-Dür) host plant use in successive spring, summer and winter seasons at one single location ...

Title of Document: LOCAL LETTUCE: HEAT TOLERANT ROMAINE CULTIVARS AND VERMICOMPOST SOIL AMENDMENT TO INCREASE SUSTAINABILITY IN THE MID-ATLANTIC. Anna Wallis M.S., 2014 Directed By: Dr. Chris Walsh Plant Science and Landscape Architecture Local production of lettuce in the Mid-Atlantic utilizing heat-tolerant romaine cultivars and vermicompost soil amendment has the potential to significantly i...

leach into groundwater after crop harvest in the fall, and depending on the species, can sequester atmospheric C Biculture legume–cereal cover cropping may enhance aboveand and/or N, thereby reducing the amount of N fertilizer belowground biomass yields and C and N contents. The increase in C and N supply to the soil has the potential to improve soil quality required for summer crops (Hargrove,...

In order to assess the occurrence, distribution and importance of viral diseases of mungbean and mashbean crops in Punjab, Pakistan, an extensive survey was conducted during summer season of 2004. The symptomatic plant samples were collected from farmer’s fields and experimental plots at research stations and tested by Enzyme-linked Immunosorbent Assay (ELISA) to detect and identify viruses inf...

PREFERENCE OF HONEY BEES, CARPENTER BEES, AND BUMBLE BEES FOR NEW CROPS IN VIRGINIA. Mark Kraemer & Harbans Bhardwaj, Agricultural Research Station, Virginia State Univ., Petersburg, VA 23806. Agricultural crops may provide important nectar and pollen resources for native bees and the European honey bee, especially during the mid to late summer period when forage resources are limited. In some ...

The green lacewing, Chrysoperla carnea (Steph.) (Neuroptera: Chrysopidae), is a generalist predator in its larval stage of most species of soft bodied insect pests, especially aphids, whiteflies, thrips, coccids, and mealy bugs. This predator had been recorded in different regions in Saudi Arabia as indigenous species. The fitness of this indigenous predator for controlling the aphid, Aphis gos...

Effluent from a swine (Sus scrofa domesticus) lagoon is often applied repeatedly to nearby fields because of logistical constraints and costs of transportation. To minimize accumulation of soil nutrients and sustain use of spray field, best management practices must maximize the rates of removal of manure nutrients. Research determined summer hay and nutrient yields of bermudagrass [Cynodon dac...
