Management practices for black lentil green manure for the semi-arid Canadian prairies

S. A. Brandt Canadian Journal of Plant Science 1999. doi:10.4141/p97-091

Other claims from this paper (10)

Intervention effect Green manure strategies did not improve succeeding wheat yield over summerfallow.
Intervention effect Green manure strategies did not improve wheat grain protein concentration over summerfallow.
Observation Standing lentil strips at bud-stage incorporation protected against wind erosion.
Intervention effect Bud-stage glyphosate without incorporation reduced available soil nitrogen.
Intervention effect Bud-stage 2,4-D amine without incorporation reduced available soil nitrogen.
Intervention effect 2,4-D did not stop lentil growth and water use soon enough to prevent a reduction in subsequent wheat yield.
Intervention effect Glyphosate generally stopped lentil water use more rapidly.
Mechanism The authors attributed the lack of wheat yield gain to summerfallow filling the rooting zone with water.
Recommendation Early incorporation with standing lentil strips was recommended if green manuring is used.
Observation Green manuring lacked a consistent advantage over summerfallow even with improved water management.

Other claims from this paper (10)

Intervention effect Plant growth, essential oil content and oil yield of Cymbopogon species decreased with increasing water salinity in all species.
Intervention effect Citral content of C.flexuosus increased under NaCl stress.
Intervention effect Geraniol accumulation in C. martinii decreased under NaCl stress.
Intervention effect Sodium accumulation in C. winterianus showed the maximum increase under NaCl stress.
Intervention effect The K/Na ratio of C. winterianus showed the largest decrease under NaCl stress.
Observation Sodium accumulation was least in C. martinii, particularly at 44 mM NaCl.
Association C.flexuosus is suggested to be more tolerant of cultivation under saline stress than C. winterianus.
Association C. martinii is suggested to be more tolerant of cultivation under saline stress than C. winterianus.
Recommendation Cymbopogon species that accumulate less sodium and have high K/Na ratios under NaCl stress are suitable for growth under saline conditions.
