Water and nitrogen management in wheat-lentil intercropping system under late-sown conditions

Abstract

Experiments comprising various ratios of wheat and lentil in a mixed cropping system under two irrigation regimes and three levels of N application are described and the results discussed. In all experiments the highest yield of grain was obtained by growing wheat alone and the highest yield of lentil grain by growing lentil alone. No mixture could equal the yield obtained by wheat alone.

Intercropped wheat (Triticum aestivum L.) and bean (Vicia faba L.) as a whole‐crop forage: effect of harvest time on forage yield and quality

“…In general, most cereal–legume research, for grain rather than forage, suggests increased yields from intercrops. This is thought to result from more efficient resource use, such as light (Watiki et al ., 1993), nutrients (Chowdhury and Rosario, 1994; Jensen, 1996; Ghanbari Bonjar, 2000), water (Ahlawat et al ., 1985) and the ability of the component intercrop species to exploit different soil layers without competing with each other (Willey, 1979). For the data reported here, such enhanced efficiency seems likely, especially for light, which may have led to less competition with weeds.…”

Effect of Different Planting Pattern on Total Dry Matter Production and Maize Forage Quality in Maize (Zea Mays) and Cowpea (Vigna Sinensis) Intercropped As Whole-Crop Forage

“…Intercropping may be more efficient at exploiting a larger total soil volume if component crops have different rooting habits, especially depth of rooting (Ahlawat et al, 1985). Lower soil moisture content in intercrops treatments compared to sole crop could not be due to higher evaporation from the soil surface, because soil temperatures under intercrops were lower than sole crops (tab.…”

Weed Control in Maize-Cowpea Intercropping System Related to Environmental Resources Consumption

“…Weeds were dried in the oven at 70°C for 48 h and weighed to record dry matter yield. Nutrients uptake by intercrop components were determined by measuring the Ca, Mg, K and P amount of (Ahlawat et al, 1985). Lower soil moisture content in intercrops treatments compared to sole crop could not be due to higher evaporation from the soil surface, because soil temperatures under intercrops were lower than sole crops (Tab.…”

“…Greater nutrient uptake is usually presumed to be possible, because of some complementary exploration of the soil profile by intercrop components (Ahlawat et al, 1985) of fuller use of resources over time (Willey 1990). High total nutrient uptake in intercropping has been reported (Bulson et al, 1997;Choudhury and Rosario, 1994).…”
