Soil surface drainage and yield of chickpea grown on vertisols in Ethiopia
A study was carried out to determine the effects of soil surface drainage and sowing dates on the yield of chickpea (Cicer arietinum L.). Three seed bed types [broad bed and furrow (BBF), ridge and furrow (RF), and flat] and three sowing dates, beginning of early August, at an interval of 14 days we...

Summary: | A study was carried out to determine the effects of soil surface
drainage and sowing dates on the yield of chickpea (Cicer arietinum
L.). Three seed bed types [broad bed and furrow (BBF), ridge and furrow
(RF), and flat] and three sowing dates, beginning of early August, at
an interval of 14 days were used. The trial was grown at Debre Zeit and
Akaki in 1987, 1988 and 1989 cropping seasons. The trial was planted in
a split plot design with 3 replications. The highest mean seed yields
of 3111.1 and 3388.9 kg ha-1 were obtained from the first sowing date
at Debre Zeit in 1988 and Akaki in 1989. Early sowing increased seed
yield by 9.5 to 48% at Debre Zeit and 17.4 to 45% at Akaki as compared
to the third sowing date (late August). There was no significant
difference among the mean seed yields of different seed bed types.
Ridge and furrow (traditional) method was as effective as BBF in
removing the excess water. Above all, it did not require additional
implement to make RF as compared to BBF which is made by broad bed
maker (BBM).
Une experience a ete conduite pour determiner les effets du drainage de
surface et de la date de semis sur la recolte de Cicer arietinum L.
Trois types de lits (lit de labour (BBF), crete de labour (RF), et lit
plat) et trois dates de semis, intervalles de deux semaines commencant
debut Aout ont ete utilises. Les experiences ont ete executees Debre
Zeit et Akaki en 1987, 1988 et 1989 en utilisant la variete Mariye.
L'essai a ete plante en schema de split plot avec trois repetitions.
Les recoltes les plus hautes de 3111.1 et 3388.9 kg/ha sont obtenues
pour les premires periodes de semis Debre Zeit en 1988 et Akaki en
1989. En comparant un semis precoce avec la troisime periode de semis
(fin Aout) la recolte des graines augmentait de 9.5 48% Debre Zeit et
17.4 jusqu'a 45% a Akaki. Il n'y avait pas de difference significative
entre les recoltes moyennes selon les types de lits. La Crete de labour
(la methode traditionnelle) etait aussi efficace que BBF en ce qui
concerne l'enlevement de l'excedent d'eau. En plus, on a pas besoin
d'outils (faiseur de lit large) pour faire RF en comparant avec BBF.
Parce que les vertisols sont aussi visqueux quand mouille, il est
difficile pour etablir une BBF pour Cicer arietinum en mi-Aout. |
