In maize-soybean intercropping system, soybean plants will be affected by the wide light-fluctuation, which resulted from the shading by maize plants, as the shading of maize the light is not enough for soybean in the early morning and late afternoon, but at noon, the light is strong as the maize shading disappeared. The objective of this study is to evaluate the photosynthetic response of soyb...

in order to study the effects of cropping systems and mulch application in relay intercropped styrian pumpkin (cucurbita pepo l.) with chickpea (cicer arietinum l.), a field experiment was conducted as factorial layout based on a randomized complete block design with three replications at the agricultural research station, college of agriculture, ferdowsi university of mashhad, during growing s...

intercropping is considered as a method for increasing yield per unit and stability. in order to evaluate the effects of phosphorous biofertilizer and chemical phosphorous on fodder quality of corn (zea mays l.) and grass pea (lathyrus sativa l.) intercropping, two field experiments were conducted as factorial based on randomized complete block design with four replications at two places simult...

An experiment was conducted at the research station of the International Centre for Research in Agroforestry (ICRAF) at Machakos, Kenya from November 1989 to February 1996 to evaluate the effect of annual and perennial legumes on soil fertility, cereal yields and economic returns. The study evaluated six cropping systems: (1) continuous sole maize, (2) maize rotated with short-duration legume, ...

Present study reports analgesic activity of petroleum ether, chloroform, ethyl acetate and methanolic extracts of leaves and seeds of Trigonella foenum-graecum Linn. (Fabaceae) using hot plate method for evaluation of central analgesic activity and acetic acid induced writhing test for evaluation of peripheral analgesic activity in mice.   All the extracts of Trigonella foenum-graecum ...

Improving plant energy conversion efficiency (εc) is crucial for increasing food and bioenergy crop production and yields. Using a meta-analysis, the effects of greenhouse gases, weatherrelated stresses projected to intensify due to climate change, and management practices including inputs, shading, and intercropping on εc were statistically quantified from 140 published studies to identify whe...

Intercropping systems influence yield variables of the component crops, such as harvest index, hundred seed weight, number of reproductive organs and number of seeds, within each reproductive unit. Two experiments were carried out at each of two sites during 1993 and 1994. The first experiment investigated the effects of seeding soybean or lupin alone or in combination with one of three forages...

Intercropping, which grows at least two crop species on the same pieces of land at the same time, can increase grain yields greatly. Legume-grass intercrops are known to overyield because of legume nitrogen fixation. However, many agricultural soils are deficient in phosphorus. Here we show that a new mechanism of overyielding, in which phosphorus mobilized by one crop species increases the gro...
