Cover crops are a sustainable management tool for mediating weed pressure, reducing soil erosion, and enhancing organic carbon (C) nitrogen (N) levels. Yet, adoption rates across water-limited farms in Texas remain low, especially among producers without irrigation access, due to concerns that cover crop use of moisture will negatively impact subsequent cash yields. This three-year trial rain-f...

Weed infestations significantly reduce the growth and yield of field crops. Herbicides are mostly used for weed management due to their quick results. However, resistant biotypes available herbicides rapidly increasing around word. This situation calls development alternative strategies. Crop rotation allelopathic water extracts regarded as most important Therefore, this two-year study assessed...

The need to increase cowpea production solve the menace of malnutrition is a global challenge and land limitations have also made intercropping indispensable. Field trials were carried out at Teaching Research Farm, Kwara State University, Malete, National Centre for Agricultural Mechanization (NCAM) Idofian evaluate growth yield cultivars sorghum with their competitive behavior in cowpea-sorgh...

in order to evaluate radiation capture and use efficiency and productivity in sole and intercropping of three crops, rapeseed (brassica napus l.), bean (phaseolus vulgaris l.) and corn (zea mays l.), an experiment was conducted in mashhad region during the growing season of 2007-2008. in this study six treatments including three sole cropping of the crops (rapeseed sown in 22 september 2007, co...

Intercropped corn (Zeu mays L.) and soybean [Glycine mux (L.) Merr.] may produce more total yield per hectare than either grown separately, ie., land equivalent ratio (LER) >l. Low N fertility, limited moisture, and weed competition have each been reported to result in high land equivalent ratios. Thus it was hypothesized that intercropping advantages were greater under stress conditions. The o...

Nitrogen (N) cycling was determined in monocultures of Sorghum bicolor (L.) Moench and alley cropped sorghum with Acacia saligna (Labill.) H. Wendl. in semiarid Northern Kenya. N input through biological N2 fixation of the acacia, N transfer from the legume to the intercrop and losses of applied N through harvest and 15 leaching were estimated using N enrichment. The biological N fixation and N...

Mixed intercropping of barley (Hordeum vulgare L.) with faba bean (Vicia faba L.) was compared with sole cropping for three growing seasons 2001–2003) at Holetta Agricultural Research Centre, in the central highlands of Ethiopia. The treatments were sole barley (125 kg ha−1), sole aba bean (200 kg ha−1) and an additive series of 12.5, 25, 37.5, 50 and 62.5% of the sole seed rate of faba bean mi...

An experiment was conducted to determine effects of inter-cropping lablab (Lablab purpureus) with 3 selected early-maturing sorghum (Sorghum bicolor) varieties (Teshale, Girana-1 and Misikir) on plant morphology, grain forage yield quality plus forage, assess farmers’ perceptions the crops in Kalu District, South Wollo, Ethiopia. Seven treatments, namely: T1 - sole (SL); T2 Teshale + (TL); T3 (...

A study was carried out to determine the composition and predominance of weed species in wheat field in Khokana of Kathmandu valley as a representative sample of mountain ecosystem in Nepal. A total of 44 weed species representing 18 families were recorded. The most abundant species were Chenopodium album, Polygonum plebeium and Spergula arvensis. With the improved temperature after February, t...
