POTENTIAL INTERCROPPING PRODUCTION OF COWPEA, CUCUMBER AND TOMATO WITH OKRA
EMAD-ELDEN FOUAD ELSAYED ELNOBI;
Abstract
A within-row intercropping investigation was conducted during 2004 and 2005 to assess growth, development and yield of okra (main crop) and cucumber, cowpea or tomato (secondary crops). The assessment was implemented in 3 separate experiments each involving okra and one of the three secondary crops. Okra and secondary crop were grown in alternate hills 20 em apart on 70 em spaced rows. Okra was planted on April 1st (2004) and April 7th (2005).
Cowpea was planted as intercrop with okra on three planting dates in 2004
(April 15
27th and June 6th) and four planting dates in 2005 (April 7th, 28th, May
l61
and June 151 . Cucumber) was planted as intercrop on two planting dates in
2004 (April 1st and 2ih) and three planting dates in 2005 (April 7th, 28th and May 16th). Tomato was transplanted as intercrop 40 days after planting okra. Sole crop treatments were also involved in the intercrop system used. Data indicated that okra/cowpea intercropping either did not affect or increased okra pod yield. Cowpea, on average, produced 231 kg dry seed yield per feddan when planted either simultaneously or 3 weeks after planting okra. In terms of intercropping evaluation parameters, 'aggressiveness' suggested that okra was dominant crop over cowpea. The land equivalent ratio (LER) of okra-cowpea intercropping, on average, for both of these planting dates and the two years, was 1.2. With regard to cucumber, fruit yield was produced only when it was planted simultaneously with okra. Okra/cucumber intercropping based on simultaneous planting of both crops depressed okra pod yield to 83.2% of the pure stand okra cultivation. Relative intercropped to sole cucumber fruit yield was 71%. 'Aggressiveness' intercropping parameter suggested that cucumber was dominant crop over okra. LER of okra/cucumber intercropping, on average, was 1.6 when both crops were simultaneously planted. Within-row transplanted of tomato after 40 days of planting okra significantly increased the percentage of survived tomato transplants. Okra yield was not affected, while no fruit set and yield were obtained from tomato whether planted within okra rows or grown as a sole crop. To benefit from added cucumber and cowpea crops, it is recommended to plant them simultaneously on the same date of planting okra.
It is also possibly to plant cowpea 3 weeks after planting okra.
