For these purposes, a pay-out of P15,000 per hectare will be adequate for annual intercrops
. However, for perennial trees and other intensively grown annuals, the farmers will need more that P15,000.
The effect of voluntary feed intake, in vitro digestibility and nitrogen balance in sheep feeding on grass silage or wheat-pea intercrops
differing in ratio at maturity.
The use of species of the genus Urochloa for intercrops
with different grain crops is feasible mainly due to its slow initial growth, which reduces competition with the main crop (Jakelaitis et al., 2005).
All the intercrops
noticed higher plant height as compared to their sole cropping which attributed to shedding effect of taller plants of pearlmillet on pulses and competition for sun light resulted into elongation of their main stem (Table 1).
In maize-legume intercrops
, it was realized that maize reduced cowpea yields more than the effect of cowpea on maize yields because of greater competitive ability of maize when intercropped with cowpea .
Van, "Microenvironment of corn-soybeanoat strip intercrop
system," Field Crops Research, vol.
According to  LER was superior in all intercrops
implying that the productivity of corn-soybean intercropping has a higher RY advantage over sole cropping under the additive intercropping system.
On the other hand intercrops
have led to increase while others have led to decrease in either VAM fungal colonisation or diversity [21, 30].
For this purpose, four intercrops
(chili, tomato, okra and cotton) and five plant spacings (10, 15, 20, 25 and 30 cm) were used in onion field crop.
Agroeconomic performance of carrot x looseleaf lettuce intercrops
in two strip arrangements.
Chickpea also has desirable agronomic advantages like fixing nitrogen in amounts of 140 kg N [ha.sup.-1], which improves soil fertility, benefits intercrops
and subsequent crops, hence increasing their yields and saving fertilizer costs .
