Abstract
A field experiment was conducted at Farmer field under Sirohi KVK, MPUAT,
Udaipur during the year 2012-13.The soil of experimental field low in nitrogen, medium in
phosphorus and high in potassium. The experiment consisted of 15 crop regulation treatments
comprising T0 (no spray),T1(Foliar spray of GA3@ 50 ppm in the month of June),T2 (Foliar
spray of GA3@ 75 ppm in the month of June), T3 (Foliar spray of NAA@ 400 ppm in the
month of February), T4 (Foliar spray of NAA@ 500 ppm in the month of February), T5
(Foliar spray of KNO3 @ 1per cent in the month of October), T6 (Foliar spray of KNO3 @ 1.5
per cent in the month of October), T7 (Foliar spray of paclobutrazoal @ 1000 ppm in the
month of July), T8 (Foliar spray of paclobutrazoal @ 2000 ppm in the month of July), T9
(Foliar spray of Cyococel @1000 ppm in the month of September), T10 (Foliar spray of
Cyococel @1500 ppm in the month of September), T11 (Paclobutrazol soil drenching @2.5
ml/plant in the month of July), T12 (Paclobutrazol soil drenching @ 5 ml/plant in the month of
July), T13 (With holding irrigation in September), T14 (Root pruning & exposure in October).
These treatments were evaluated under one way analysis of variance replicated thrice with
adopting uniform cultural schedule during the experimentation.
The results revealed that all treatments significantly increased the vegetative growth
characteristics (shoot growth, shoot girth and leaf area) and flowering characteristics
(initiation of flowering, number of flower per shoot, 50 per cent flowering, per cent fruit set,
per cent fruit retention), yield characteristics (fruit weight, fruit volume, peel thickness,
number of seeds fruit-1, number of fruits plant-1, yield tree-1 and yield hectare-1) and
qualitative characteristics, (juice per cent, TSS, acidity, ascorbic acid content, pH and
organolepting observation & leaf NPK status). Among the treatments foliar spray of cycocel
@ 1000 ppm in the month of September (T9) significantly increased the number of flower per
shoot (60), per cent fruit set (20 %), initiation of flowering (2 November), 50 per cent of
flowering (10 November), fruit weight (48.12 g), fruit volume (46.44 cc), number of fruits per
plant (634), yield per tree (30.50 kg tree-1) estimated yield per ha ( 8.47t ha-1), juice per cent
(52.78 %), acidity per cent (7.26 %), ascorbic acid (39.20 mg/100 ml juice) and organoleptic
score (8.95) and less number of seeds per fruit (9.67) and juice pH (2.00). As far as relative
economics of the treatment is concerned, T9 treatment exhibited significantly higher gross
return (Rs.211750 ha-1), net return (166831 ha-1) and B: C ratio (3.71:1).
