i I INTRODUCTION :
-_ _-"~-__
In order to increase and stabl.l.ize trop production
iii the semi-ar id tropic:;,
it 1s imparative I-hat any technology
foi. land and water mar.agement, and trop production must be
aimed at improved ressource management wich the soi1 and rainfall
efficiency. Inter cropping is a system for achieving good yie2.d.
Sorghum,
one of the main trop in the S.A,T.area,
and cowpea are
adapted to grown on the same field.

I'7- RESULTS AND DISCUSS:ION
..-_ -_I_--- .---- ~.~__.~
:Scryhum
-._ ._ There was a significant dj fference statically
0etween
_ _
the combinaison T6 i2CP--2s) i T_1. (Sc.113 SORG), 'Il'4 (25 :2c'P)
and
T5 (2S:3C:F), T3 (lS:3CF).
The yield in T6 - T1-T4 are equal statical.ly,T; are
the lcwest : hcwever the combinaison T6-(2CP--2S) yielded more
grain yield than sole scrghum. T6 was l.,28 highest than sole scrghum
but T:i Sole scrghum are highest than T3 -' T4 - T5.
Acoording tc ccwpea : sole cowpea yield grain was more
than intercrcp 1.2% more than T6 688kg/ha. T5 are the lcwest, in
this treatement tree Rows of ccwpea affected the yield.
In this experient. the best combinaison is T6 (2CP-2s). Land
Equival ent ratj c
(LE:R) and mcnatary value are ccmpared between trea-
tement.s.T6 and 1'4 are statically equal and different tc T3, T5,
these twc treatements are alsc equal.

CONCLUSLON :
_ _ _---..---
'IX L Cowpea, 2 Sorghum are the best rcmbinaison.
1 Sorghum,
3 Cowpea are the lowest.
‘I%f2 low yield is due in one part to shoot fly damage (shoot fly
tlamage is observed visually and scored 5).
This year also, crops are seriously suffuring 1Erc.m water deficit
(477mn-l in .L;985 1 i june t-o 16 0ct’obe.r but In this case intercropping
cereals and legumes are good combinaison for suppleying the trop
product:Lon deficit.
