Description The present investigation entitled “Comparative performance of water soluble and routinely used fertilizer in banana cv. Grand Naine under drip irrigation” was conducted at Soil and Water Management Research Farm, N.A.U., Navsari during 2011-12 and 2012-13. The Soil of the experiment was clay in texture, low in available N, medium in available P2O5 and high in available K2O.
A field experiment with 12 treatment combinations comprising of two fertilizer sources (S1: Routine fertilizers- Urea + orthophosphoric acid + MoP, S2: Water soluble fertilizers -Urea , 12:61:00, 13:00:45), three fertigation levels in different percent of RDF (L1: 80 %, L2: 60 % and L3: 40 %) and two fertigation frequencies (F1: once in week and F2: twice in week) and two controls i.e., surface control and drip control were tested in FRBD with three replications.
The results indicated that the fertilizer sources had
significant effect on growth parameters and maximum plant height (3rd and 7th MAP), stem girth (3rd, 5th and 7th MAP), total leaf area (3rd and 5th MAP) was recorded with water soluble fertilizers (S2). Yield parameters like length of bunch, weight of bunch and yield were also influenced significantly and higher values were obtained with water soluble fertilizer (S2). Moreover, fertilizers sources failed to exert any significant effect on treatment like crop duration, quality of fruit and soil and leaf nutrient status and all the remaining growth and yield parameters.
Considering the effect of fertigation levels, viz., 80 % RDF (L3) recorded the maximum values for morphological characters observed at various stages of growth of banana i.e. at 3rd, 5th and 7th MAP and after harvest in banana cv. Grand Naine. The same treatment was found better with respect to crop duration parameters viz., early initiation of inflorescence, maturity of the fruit as well as total crop duration and yield characteristics like, length of bunch, number of hands per bunch, number of fingers per bunch, maximum finger length and girth (cm), bunch weight (kg), and yield (t/ha) followed by L2 (60% RDF). Similarly, this treatment had maximum shelf-life in days with quality parameter like, higher value of acidity, reducing sugar and total sugar. At 2nd, 4th, 6th MAP and after harvest, available N, P2O5 and K2O in soil as well as at 6th MAP available NPK in leaf were recorded maximum in 80% RDF.
Among the fertigation frequencies, fertigation applied at twice in a week (F2) induced early and vigorous vegetative growth at 3rd, 5th and 7th MAP and at harvest in terms of plant
height, stem girth, number of leaves and total leaf area. Ultimately this treatment produced the plant with higher length of bunch, number of hands, number of fingers, length and girth of finger, higher weight of bunch and yield per hectare. It also produced favorable effect on fruit quality in terms of TSS, total sugar and reducing sugar, acidity per cent. Moreover, fertigation frequencies failed to exert any significant effect on crop duration and soil and leaf nutrient status of banana cv. Grand Naine.
In drip control v/s rest, all the rest of the treatments except 40% RDF were recorded higher values in different characters like, plant height, length of bunch, weight of bunch and yield. However, stem girth, total leaf area and finger length and girth were recorded maximum in treatment S2 (water soluble fertilizers), L3 (80% RDF) and F2 (twice in a week) as compared to drip control. In comparison of surface control v/s rest treatment, all factors were found significantly superior with respect to average bunch weight and yield (t/ha) as compared to surface control. Whereas, Drip control v/s treatment mean failed to produce any significant effect during the present study.
From the economic view point, the higher net realization was obtained in treatment S1 (Routinely used fertilizer), L3 (60% RDF), F2 (twice in a week). Regarding drip control it was observed that net realization was higher than L1 (40% RDF), S2 (water soluble fertilizers) and F1 (once in a week)). However, in surface control net realization was recorded minimum as compare to all the factors.
