A total of 15 years of experimentation
period (1995–2010) was divided into two phases. In the
first phase (1995–2005), five mango based agri - horticultural
models (AHM) viz. Mango ? cowpea–toria,
mango ? cluster bean/okra–toria, mango ? sesame–
toria, mango ? black gram–toria and mango ? pigeon
pea in addition to sole mango plantation (no
intercrop) and in second phase (2005–2010), two
mango based AHM (mango ? colocasia and
mango ? turmeric) in addition to sole mango (no
intercrop) were studied. The mean maximum cowpea
equivalent yield (t ha - 1) was harvested from cowpea
(1.84) followed by okra (1.21), black gram (1.11),
sesame (0.68) and mean minimum with pigeon pea
(0.58). The crop yield reduction among the mango
basedAHMwas observed from third year to tenth year.
The positive correlation was found between light
transmission and intercrops yields amongst all models
during both phases. However, the correlation between
mango canopy spread and intercrop yields shown
negative trends. The yield reduction in intercrops
varied from 37.0–52.6 % during first phase and
20.6–23.5 % during second phase of experimentation
compared to sole crop. The results revealed that the
fruit based AHM were effective in improving fruit
yields of the mango. The mean maximum fruit yield of
mango (7.02 t ha - 1) was harvested with cowpea–toria
crop rotation followed by black gram–toria
(6.59 t ha - 1) and minimum fruit yield (5.76 t ha - 1)
realized with sole mango tree during first phase
(1999–2005). Likewise, mean maximum fruit yield
(13.71 t ha - 1) from mango tree was obtained in the
turmeric block followed by (13.00 t ha - 1) in colocasia
block and minimum fruit yield with sole mango tree
(11.86 t ha - 1). All the treatments of AHM recorded
higher soil moisture as compared to sole mango
plantation during both phases. The moisture retention
under different AHM was in the order of cowpea
(13.32 cm) black gram (13.29 cm) pigeon pea
(13.27 cm) okra (12.42 cm) sesame (12.17 cm)
sole mango (11.62 cm) during first phase, whereas
moisture retention was observed in the order of
turmeric (14.20 cm) colocasia (14.01 cm) sole
mango (12.60 cm) during second phase. The cowpea–
toria crop rotation with mango gave maximum
benefit: cost ratio followed by okra–toria under rainfed
conditions. Besides economic viability of cowpea–
toria with mango, this system had improved tree
growth as well as fruit yield of mango. In the second
phase, mango ? turmeric yielded more benefit than
mango ? colocasia system. In the first phase, the
mango ? cowpea–toria system improved organic carbon,
total nitrogen, phosphorus, potash and reduced pH
by 49.0, 56.3, 48.6, 58.5 and 11.6 %, respectively as
compared to initial values whereas mango ? turmeric
system increased organic carbon, nitrogen, phosphorus,
potash and reduction inpH by 51.0, 45.0, 29.7, 29.0
and 3.4 %, respectively over initial values within soil
depths of 0–30 cm during second phased. Mango
based AHM is recommended for adoption with selective
intercrops up to 15 years of age of mango
plantation for multiple outputs and good economic
viability without impairing site fertility.
