(Bahadur and Singh 2001). The losses of water can be minimized by using
of sprinkler and drip irrigation system. Under fan pad polyhouse condition
the crop yield can be improved by 65.40% in tomato and 67.70% in capsi-
cum through drip system of irrigation along with water saving of 43.23%
and 42%, respectively (Singh et al.
,
2010).
5.5.3.2 FERTIGATION
The application of fertilizer through irrigation system (fertigation) has be-
come a common practice in modern irrigated agriculture. Increase yield,
improvement in quality of product, irrigation and fertilizer use efficiencies
and protection of soil environment are some of the main characteristics of
this method, which made it popular throughout the world. The reason why
fertigation become the state of art in vegetable cultivation is that nutrient
can be applied to plants in the correct dosage and at the time appropriate
for the specific stage of plant growth (Clark et.al., 1990).
5.5.4 SOIL MANAGEMENT
Due to excess rains during the month of June-September the soil nutrient
like, Ca, Mg, K and N getting lost from the soil by the process of leaching
and developed into laterite soil with rich in metal ions like, Fe and Al, etc.
by the process of cauterization. Most of the soils of northeastern are acidic
in nature with pH range of 4.0-5.5 due to the above factors and process
most of the crops face problems of deficiency of leached nutrient and tox-
icity of metal ions as well. In order to get better produce farmers can adopt
following management practices as given below.
5.5.4.1
USE OF SOIL AMENDMENTS
To neutralize the effect of soil acidity and toxicity of metal ions on the
crops, farmers can use the soil amendments like, lime.
