Abstract
The field of investigation entitled “Effect of different levels of nutrients and irrigation through
drip system in Kinnow” conducted in two experiments, i.e., (i) Effect of irrigation level and NPK
fertigation on growth, yield and quality of Kinnow and (ii) Effect of micronutrients application through
drip on growth, yield and quality. The Experiment-I and Experiment-II were undertaken in the
Experimental Block of Department of Horticulture, CCS HAU, Hisar and in farmer’s commercial
Kinnow orchard at Dhani Majra Village, Fatehabad District, respectively, from February 2014 to
January 2016.
The Experiment-I comprised of three drip irrigation levels viz., 1.0V, 0.8V and 0.6V of water
along with four recommended dose of fertilizers viz., 120%, 100%, 80% and 60% of recommended
dose of fertilizers. Interaction effect of drip irrigation and drip-fertigation had significant influence on
growth characters viz., plant height, stem girth and plant spread. The statistically maximum fruit yield
(272.30 q ha-1) and nutrient use efficiency (142.80 kg kg-1) were recorded with 0.8V water along with
80% of recommended dose of fertilizers. The leaf N, K and Fe composition was statistically higher in
the same treatment combination. The leaf P was highest when irrigation at 1.0V was combined with
120% RDF. Total chlorophyll content in leaves was maximum with combined application of 0.8V
water and 120% RDF. The overall results of this study indicated that the application of 0.8V of water
with 80% RDF through drip system could be productive with sufficient available nutrient for Kinnow
production under semi-arid condition of Haryana.
The Experiment-II on micronutrients application comprised of six treatments, viz., T1- FeSO4
42g + MnSO4 21g + ZnSO4 14g, T2- FeSO4 84g + MnSO4 42g + ZnSO4 28g, T3- FeSO4 126g + MnSO4
63g + ZnSO4 42g, T4- FeSO4 168g + MnSO4 84g + ZnSO4 56g, T5- Foliar spray of 0.5% each of
FeSO4, MnSO4, ZnSO4 + 1 % Urea and T6- Control (No micronutrients). T1 to T4 treatments were
applied into soil in four equal split doses. Foliar spray was also carried out four times at the time of soil
application of micronutrients. All micronutrients treated plants produced higher plant growth, fruit
yield and superior quality fruits over control. However, foliar application of micronutrients
significantly outyielded (289.40 q ha-1) the other treatments. Statistically higher level of leaf nutrients
such as N, P and Zn were extracted with foliar application.
