Abstract
The field experiment was conducted at Water Management Farm, CSK HPKV,
Palampur during rabi 2012-13 to optimize micro sprinkler irrigation and NK fertigation
in garden pea (Pisum sativum var. hortense L.). The soil of the experimental field was
silty clay loam in texture; acidic in reaction; high in organic carbon; medium in available
nitrogen; high in available phosphorus and low in available potassium. The experiment
was laid out in factorial randomized block design with three replications, consisting of
nine treatments i.e. comprising of all the possible combinations of four irrigation depths
(0.4, 0.6, 0.8 and 1.0 CPE) and two NK fertigation levels (50 and 100 per cent of adjusted
recommended dose) plus one control (basal application of soil test based NPK fertilizer
and surface irrigation of 5 cm). Micro sprinkler irrigation at 0.8 CPE resulted in higher
soil water status leading to better shoot growth and dry matter accumulation which
resulted in higher green pod yield and NPK uptake. Fertigation with 50 per cent of
recommended dose gave comparable yields to 100 per cent recommended dose.
Treatment combination of 0.8 CPE and 50 per cent recommended dose gave higher pod
yield, NPK uptake and net returns. Water use efficiency was higher in micro sprinkler
than flood irrigation.
