Title

Other claims from this paper (11)

Intervention effect Tillage practices had no significant effect on cowpea emergence percentage, leaf number or branch number.
Intervention effect No-till with herbicide (NH) gave superior cowpea plant height over the other treatments in the first season.
Intervention effect No-till slash and burn (NSB) increased cowpea plant height in the second season.
Intervention effect Minimum ploughing (MT) increased cowpea plant height in the second season.
Intervention effect Pod and grain yield were not affected by tillage treatments in the first season.
Intervention effect No-till slash and burn (NSB) gave 1.84 t ha-1 pod and grain yield in the second season, superior to other treatments.
Intervention effect Minimum ploughing (MT) gave 1.53 t ha-1 pod and grain yield in the second season, superior to other treatments.
Intervention effect The highest cost of production was under NSB.
Intervention effect NSB treatment had higher soil bulk density at sowing and 6 WAS than the other treatments.
Intervention effect NH had higher soil moisture content at 6 WAS than the other treatments.
Recommendation With optimum precipitation, conventional tillage appears a better land preparation option for cowpea.
