Description Field experiment was conducted during kharif 2013 to study the “Influence of
Integrated Nutrient Management on Bitter gourd crop cv. Prachi on its growth, yield, quality,
nutrient uptake and recovery. The soil of the experimental site was sandy in texture near
neutral reaction, low in available N and K but high in available P. The test crop received 10
different treatment combinations of inorganic, organic and bio fertilizers viz. 50%NPK(T2),
50%NPK+VC (vermicompost)(T3), 50%NPK+ VC+BF (Biofertilizers) (T4),75%NPK (T5),
75%NPK + VC(T6),75%NPK +VC+BF(T7),100% NPK(T8),100%NPK+ VC(T9),100%
NPK+ VC+BF(T10) along with absolute control(T1).The biometric observations recorded
were vine length, days taken for first male and female flowering, chlorophyll content, leaf
area, fruit length, girth, unit fruit weight number of fruits/plot and yield per hectare.
Application of recommended dose (150:50:100:50:10:15 kg of NPK and S, Zn, Bo per
hectare inorganics with VC @2.5 t ha-1 and BFs (Azotobacter, Azospirillum and PSB @ 4kg
ha-1) (T10) recorded maximum vine length(533cm),number of branches per vine, least number
of days taken for male (39.6 days)flower as well as female flower anthesis (44.0 days) and
female flower appeared at earliest node (24th internode).The same treatment recorded
maximum number of fruits per plant(40nos),fruit length(17.6cm),girth (13.4cm), unit fruit
weight(86.4g),fruit yield(4036kg ha-1), ascorbic acid(111.1mg/100g),TSS(2.0ᵒ Brix),protein
content (1.76%).Significantly higher amount of N(46.7%) with recovery of 21.3%,P uptake
of 9.0 kg ha-1 with recovery of 20.1 %,K uptake of (74.1 kg ha-1) with recovery of 34 percent,
and uptake of 4.3kg ha-1 with a recovery of per cent were recorded with recommended dose of
inorganics with vermicompost and biofertilizers (Azotobacter, Azospirillum and PSB @1:1:1
ratio). The results indicated for soil test based recommended dose of inorganic nutrients with
correction of soil deficient’s with integrated use of organics as vermicompost and
biofertilizers like Aztobacter, Azospirillum and PSB in 1:1:1 each applied @4 kg ha-1
inoculated to prelimed vermicompost in 1:25 ratio incubated for 7 days at 30% moisture is the
best recommended practices for getting optimum yield with higher nutrient recovery for bitter
gourd crop.
