Soil surface drainage and yield of chickpea grown on vertisols in Ethiopia

Abstract
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).

Résumé
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.
