The replanting of senile, unproductive coconut palms and planting of tree intercrops
like coffee, cacao, black pepper, pineapple, and various fruit crops will take longer but will be lasting.

against weeds and the interactions with crop productivity and soil N availability.
In Africa, legumes have been tested as components of grass-legume mixtures, used to reinforce native pastures, established as fodder-banks, planted as intercrops
and in leys, and in some cases, sown under trees in plantations (Thomas and Sumberg, 1995).
However, soil cover crops compete with grain crops in intercrops
under water deficit conditions, thus reducing their productive potential (Silva et al., 2014).
To improve biological yield, Pinto & Pinto (2012) claim that intercrops
are very common in Northeast Brazil and aim to enhance the efficiency of production factors.
For the farmer, growing the legume has proved a quite profitable venture compared to the farming of the regular beansSince farmers in parts of western Kenya grow their crops in two seasons a year, Kageya intercrops
the beans and maize in the first season then grows the beans alone in the second.But she not only grows the legume for the market.
Plant height of pearlmillet at maturity was statistically equal, but found higher in sole pearlmillet as compared to pearlmillet with intercrops
(Table 1.) which might be attributed to higher cell elongation due to auxin accumulation in plants (Malik and Srivastava, 1982) and (Choudhary, 2009) moreover, light availability was comparatively lesser due to higher plant densities under sole crop.
In addition, there is no information on whether the choice of accession affects maize/roselle intercrops
. The objective of the study was to test and identify roselle accession(s) whose yield would increase or be maintained when intercropped with maize without negative yield implications on the maize crop.

: an alternative pathway for sustainable agriculture," Australian Journal of Crop Science, vol.
Several scientists have been working with cereal- legume intercropping systems and proved its success compared to the monocrops  Some studies have indicated that intercropping was more productive than sole cropping because of the complimentary effect of intercrops
such studies included amaranth with cowpea, cucumber with cowpea , maize with cowpea  and cassava with cowpea
