The spatial variation in plant species associated with intercropping is intended to reduce resource competition between species and increase yield potential. A field experiment was carried out on corn (Zea mays L.) and soybean (Glycine max L.) intercropping in a replacement series experiment with weed contamination consist of: weed free, infestation of redroot pigweed, infestation of jimsonweed...

introduction the lentil or masoor (lens culinaris l.) is a brushy annual plant of the legume family, grown for its lens-shaped seeds. lentil has been one of the first crops domesticated in the near east. with 26% protein, lentil is the vegetable with the highest level of protein other than soybeans, and it is an important part of people’s diet in many parts of the world. it is reported that the...

Loblolly pine (Pin1r.s tae(/(i L.) seedlings were grown in co~npetition with native weeds using soil and seed bank collected from recently chopped and burned areas near Appornattox, Virginia. One-year-old seedlings were planted and weeds allowed to germinate from the native seed bank while being exposed to COz (ambient and elevated approximately 700 ppm) and water (water stressed and well water...

A two-year field experiment was carried out to investigate the effects of nitrogen, composted manure, municipal waste compost, and weeds on yield and photosynthetic characteristics of corn. Experimental design was split split plot factorial with 3 replications. Main plots were weedy and weed-free, sub plots were nitrogen fertilizer levels [0 (N0) and 200 (N200) kg N ha -1 as urea], and sub sub ...
