The present study was conducted at experimental farm of CSK HPKV, Palampur,
during the year 2012-2013 with the objectives to evaluate the effects of drip irrigation
levels and different methods of fertilizer application on soil water retention and
transmission, plant water and water use efficiency, quality parameters, growth,
productivity and nutrient uptake by broccoli. The treatments comprised of (a) three
drip irrigation levels viz., I -Drip at 40% CPE, I -Drip at 60% CPE and I -Drip at 0.4 0.6 0.8
80% CPE (b) three fertilizer application levels viz., F -100% recommended dose of 100
fertilizer through fertigation, F -25 % recommended dose of fertilizer through C25+F75
conventional method as a basal dose and 75% through fertigation and F -100% of CF
recommended dose of fertilizer through conventional method and fertilizers, (c)
control-Flood irrigation of 4 cm at 8-10 days interval + 100% recommended dose of
fertilizer and (d) absolute control- No fertilizer and flood irrigation of 4 cm at 8-10
days interval. The broccoli cv. Palam Samridhi was transplanted on October 31, 2012.
The results indicated that I and I treatment had higher soil water content, soil 0.8 Rec
water stock, profile water recharge in comparison to I and I . The I treatment due 0.4 0.6 0.8
to favorable soil moisture regimes led to better root and shoot growth, higher relative
leaf water content, marketable curd yield, TSS, ascorbic acid, chlorophyll content,
NPK uptake, fertilizer use efficiency with respect to N, P and K and water use
efficiency in comparison to I , I and I . Likewise, F and F treatment had 0.4 0.6 Rec 100 C25+F75
higher root and shoot growth, relative leaf water content, marketable curd yield, TSS,
ascorbic acid, chlorophyll content, NPK uptake and water use efficiency in
comparison to F . The marketable curd yield obtained under I F was at par with CF 0.4 100
I F treatment, which resulted in saving of 20% irrigation water. The study 0.6 100
concluded that drip based irrigation scheduling resulted in higher water use efficiency
(44.68% to 54.88%) and saving in irrigation water (43.25% to 48.90%) in comparison
to conventional method of irrigation.
