Seven different treatments combination of commercial formulation of growth regulators (cytozyme and biozyme) and micronutrients (tracel2) were evaluated against the control (distilled water ). Though each formulation has beneficial role in improving the fruit physical and quality characters of fruits of pineapple, the treatment combination cytozyme @ 0.10% + tracel 2 @ 0.40% was the best in this regard.
[email protected] ppm sprayed at 40-50 leaves stage was the best for fruiting characteristics of pineapple in the Cooch Behar zone of West Bengal.
Pineapple cubes packed in glass bottles were found to absorb less moisture as compared to other packaging materials upto 6 months followed by 25µm thick polyvinylidene chloride (PVDC) pouch.
The effect of NAA and ethrel on the induction of flowering on pineapple was studied and concluded that ethrel 50 ppm in combination with NAA 10 ppm can be used for good quality fruits as well as higher yield and quality.
Morpho-taxonomical characterization and evaluation of 10 mango cultivars (Gulabkhas, Dashehari, Arka Aruna, Biswanath Chatterjee, Amrapali, Mallika, Chinese Dofala, Jessore Dofala, Alphonso, Bangalora) were studied and concluded that the overall performance of the cultivars Amrapali, Jessore Dofala, Mallika, Gulabkhas and Dashehari was best in terai region of WB inspite of some negligible demerits as these cultivars can be commercially grown.
Cultivar Karpuravalli performed best regarding the yield (30.6 kg/plant) followed by Rasthali or Malbhog (25.4 kg/plant) and other yield attributing characters. Among the quality parameters TSS was found to maximum in Karpuravalli (22.6 oBrix) followed by Rasthali (19.2 oBrix). Total sugar content was also highest in Karpuravalli (21.48%) with minimum acidity (0.42%). Karpuravalli was found to suitable large scale plantation in Terai Zone of West Bengal.
Genetic diversity was studied among 28 land races of banana collected from traditional farming area of North Bengal and North East India using Random Amplified polymorphic DNA (RAPD). The PCR products produced by 10 polymorphic primers revealed 66 bands, 55 of which were polymorphic (72.7%). A dendogram was constructed based on Dice’s coefficient matrix by un-weighted pair group mean analysis using NTSYS-PC, which reveal two major groups of banana: plains (North Bengal) and high hills (Arunachal Pradesh & Sikkim). The extent of variability was 86.96% and the average inter and intra-population variability ranged from 45 to 52%.
The performance of Banana cv. Nendran under different doses of NPK was studied. The treatment T6 (N 250, P 80, K 350 g/plant) recorded significantly maximum pseudo-stem height, pseudo-stem girth, no. of leaves, least phyllochron, minimum days for shooting and maturity, whereas, parameters like petiole length, leaf area, number of suckers per plant, fruit size, finger number per branch, hand number per branch, hand weight, bunch weight, pulp% , pulp: peel ratio, dry matter %, TSS, total sugar, reducing sugar and minimum acidity were prominent under T9 (N 250, P 80, K 400 g/plant) over control.
Effect of different micronutrients and growth regulators on the performance and post harvest life of banana (cv. Malbhog, Musa, AAB) was studied. It was found that out of the growth regulators used combination of 100 ppm 2,4-D was the best whereas among micronutrient treatments. 2.0g/plant borax along with 2.0g/plant zinc sulphate as soil application or 0.5% borax along with 0.25% Zinc Sulphate as foliar application was considered best for overall growth, yield and quality of malbhog. Green life, yellow life and shelf life were maximum under 05% KMnO4 solution for 15 minutes with poly ethylene packaging in controlled temperature condition, i.e., 12.5OC. Spraying GA3 and 2,4-D both at 100 ppm along with 0.25% borax and 0.25% zinc sulphate was best for production of fruits with less presence of lump.
Among the six papaya cultivars (Pusa Delicious, Pusa Giant, Pusa Majesty, Pusa Nanha, Pusa Dwarf and Ranchi) tested, Cv. Ranchi was found superior in overall growth characters. However, cv. Pusa Giant produce the highest yield of 79.20 t/ha. But the quality was found superior in cv. Pusa Delicious.
Papaya plants cv. Ranchi supplied with 400g N, 350g P2O5 and 600g K2O recorded highest yield of 94.49 t/ha with good quality fruits.
A trial was conducted to study the efficacy of PSM (Bacillus megatherium +Aspergillus awamori) and VAM (Glomus mosseae + G. fasciculatum) biofertilizers with graded levels of phosphorus (P2O5 at 50,100,150 and 200g) on growth and nutrient uptake of Papaya cv. CO-2. A general dose of nitrogen (300g N/Plant) and potash (400gK/Plant) was applied with FYM during transplantation. Chemical fertilizers were applied in four split doses in the form of urea, single super phosphate and muriate of potash. Maximum plant height (192.67 cm), girth (24.00 cm) and total number of leaves (25.17) were observed in VAM + 200g P2O5. VAM were also found effective in increasing height and girth than PSM. Early flowering was noticed due to application of increased phosphorus level and bio-fertilizer inoculation. Highest yield (64.85tons/ha) was resulted due to the inoculation effect of PSM and 200g P2O5 treatment combination. P & K content of leaves increased with increasing phosphorus level and bio-fertilizer application.
Treatment of papaya seed, after removing the mucilaginous coating immediately after collecting from fresh ripe fruits, with GA3 @150 ppm was found best in respect to seed germination (72.2%) followed by sodium thiosulphate @20 ppm (68.1%). But maximum seedling growth was observed under GA3 @ 200 ppm. Borax @0.50% along with ZnSO4 @ 0.25% also markedly improved the seedling growth.
Spraying of different level of boron, Zinc and their combinations improved the growth yield and quality of papaya plants cv. Ranchi. However, among the various treatments papaya plants sprayed with borax @0.5% [email protected] 0.25 was found best for increasing plant growth, fruit yield(37.20 kg/plant) and qualitative parameters(TSS-6.81OBrix; Ascorbic acid-57.11 mg/100g and β-carotene-3327.14μg/100g).
Maximum survival (89.83%), maximum number of branches (5.08), leaves (34.30), roots (35.66), leaf chlorophyll content (45.41 mg/100g), stem diameter (10.64 mm), root diameter (2.68 mm), average length of roots (15.83 cm), root dry weight (1.48 g), and shoot dry weight (22.73g) were observed in lemon cutting (semi-hard wood) treated with IBA at 2500 ppm, followed by NAA @1250 ppm. However, higher dose of IBA showed an inhibitory effect on most of the characters.
Green mould and blue mould of mandarin orange caused by Penicillium digitatum and P. italicum, respectively contributed 20-30% of the total post harvest losses in Cooch Behar district during the months of Novemebr-February. The incidence of disease increased from November to January causing nearly 2.6-3.9% of monetary loss in pundibari market.
To develop a self stable product from orange segment using osmotic dehydration, osmotic dehydration was optimised at temperature of 37.50OC, time of 277.50 minutes, agitation of 52.50 rpm, sugar concentration of 44.13% and vacuum drying was optimised at temperature at 56.08OC, duration 1868 minutes, and pressure of 36.22 kPa. The final quality of the osmotically dehydrated orange segments was found to have a moisture content of 55.11+3.59%, water activity of 0.767±0.036, total sugar of 34.83±2.76%, vitamin C content of 421.244±3.799 mg/100g, colour (L*, a*, b*) 53.21±1.55, 11.49±0.66, 21.26±4.12, texture (firmness, stickiness) 0.163±0.03N, 0.0016±0.00009N, antioxidant of 71.34±1.39%.
The agro- climatic condition of Cooch Behar dist. of West Bengal is quite suited for commercial cultivation of Litchi. Among the existed Litchi plants 6.25%were drooping and rest were spreading or upright in nature. Flowering started from 3rd week of February and continued upto 4th week of March. About 44% plants showed compact inflorescences and other showed medium and loose inflorescences. Maximum trees (62.5%) showed mild biennial bearing habit which might be due to the poor management practices and inferior planting materials and it decreased gradually with the advancement of the age. Extent of fruit drop were high in 27.78% trees and it was low in 20.83%trees rest plants showed medium extent of fruit drop.
Nine promising cultivars of strawberry were grown during September, 2000 to April 2001 at the University Farm of Pundibari to estimate leaf area under non-destructive way, as leaf area is one of the dependable bases to assess the production potential of a crop variety. Co-relation co-efficient between length and breadth, measurement of side and top leaflets with leaf area obtained leaf area meter for each cultivar and over the cultivars for the estimation of area of trifoliate leaves or its leaflets (side and top) using measurements of lengths and breadths of top and side leaflets. The estimated values of leaf area calculated with the help of regression equation derived from the length and breadth measurements of side and top leaflets of a cultivar varied significantly (<0.1%) from actual leaf area obtained under leaf area meter for that cultivar, indicating a high degree of precision of the non destructive way of leaf area estimation. The common equation irrespective of cultivars for the estimation of area of trifoliate leaf may be Y=165.91X-2716.35 or Y=161.03X1-2121.8, where Y=estimated area of trifoliate leaf, X=breadth of top leaflet and X1=breadth of side leaflets.
Effect of different nutrient and mulching materials on yield, quality as shelf life of strawberry cv. Chandler was studied and concluded that using straw mulch has a good prospect of getting higher yield and profits.
Assessment of quality characteristics upon enzymes assisted juice extraction from plum was made. The results of the study suggested that pectinase enzymes at a concentration of 10 units/ml were found to increase yield significantly over control. The treatment with celluase @ 6 units/ml was found to produce juice with best colour properties. Considering all parameter studies it was concluded that fruit mash with Hemicellulase @ 9 units/ml was found best.
For seedling production, treatment of jackfruit seeds with GA3 @ 100ppm was considered best as seedlings possess higher plant height, more number of leaves per plant and moderately higher survivability.
The physico-chemical characteristics of three cultivars of sapota (Cricket Ball, Kalipatti, and Badami) were assessed during the 1999-2000. The average fruit weight varied from 84.33 g in Cricket Ball to 65.66g in Kalipatti and it was intermediate (78.00 g) in Badami. Fruits of Cricket Ball content maximum TSS (20.8%) followed by Badami (18.53%) and it was minimum (18.20%) in Kalipatti. The titrable acidity of all the varieties was almost same and the lowest value of 0.17% was recorded in Cricket Ball. The ascorbic acid content was very low in all the varieties ranging from 3.63 mg/100 g pulp in Kalipatti to 2.77 mg/100g of pulp in Cricket Ball.
Shelf life of yellow and purple passion fruit squash was studied. Determination of shelf life was based on organoleptic score and mould count. After storing for six month best composition for passion fruit squash was found as follows:
|Passion fruit squash||Juice (ml)||Sugar (mg)||Water (ml)||Citric acid (mg)||Preservative (mg)|
0.6 (Potassium metabisulphite)
0.75 (Sodium benzoate)
BURMESE GRAPE/LATKA (BACCAUREA SAPIDA)
Latka is an ever green, short to medium height plant belongs to the family Euphorbiaceae. It bears flowers during March-April and fruits are available during rainy season, 3-4 months after flowering. Matured laka fruits are yellow or yellowish brown in colour. Sub-acid latka is consumed fresh.
Among the physical parameters fruit showed total weight and peel weight of 9.0 g and 3.75 g, respectively. Among the bio-chemical parameters, fruit resembles 9.86Obrix TSS, 4.42 % total sugar, 2.93 % reducing sugar and 2.1 % acidity.
An attempt has been made to evaluate the physical and biochemical properties of different Burmese grape genotypes in northern parts of West Bengal. The present investigation was carried out with twelve germplasms. The data represented from the experiment revealed that the germplasms varied among themselves regarding different physical and biochemical attributes of fruits in fully ripe condition. The maturity for fruit harvesting is least in Accession No. 9 (78.33 days) followed by Accession No. 8 (80.66 days) and it is maximum (90.33 days) for the Accession No. 7. For most of the desirable attributes, the Accession No. 11 showed better response ike maximum length (3.383 cm), diameter (3.513 cm), weight (19.93 gm), juice content (74.10 ml/10 fruit) and lowest acidity (1.996%).
Developmental pattern of Burmese grape was carried out in respect to different physical and biochemical aspects of fruits on the plants of farmers house hold nearer to the Uttar Banga Krishi Viswavidyalaya, Pundibari, Cooch Behar, West Bengal. All the plants aged between ten to fifteen years and were well grown, free from pests and diseases. After fruit set, the required fruit bunches were tagged on all sides to obtain uniform result. The fruits were harvested and subjected for studies on physico-chemical changes from 30th days after fruit set and continued up to 86th days after fruit set at weekly interval. Fruit size (length and diameter), juice content increased while peel thickness and seed weight decreased with advancement of maturity. Notable increase in TSS, sugar content and sugar: acid ratio were observed with decrease in acidity. At the time of harvest the fruits have attained TSS around 12.13OBrix, acidity less than 2.16%, 4.18% total sugar and pericarp colour should be yellowish green. Considering the fruit size, fruit weight and all the fruit quality characteristics it is suggested that the Burmese grape can be harvested in between 80-85 days after fruit set for best desert quality.
Tree growth habit and crown shape of Burmese grape was semi erect and irregular, respectively. The flower bud differentiation of male and female accessions started from first week of February to mid week of February. During the growth and development of the fruits the physical parameters like fruit length, breadth, weight, peel weight, seed weight and pulp percentage increased significantly after every seven days till maturity.
PANIAL/INDIAN PLUM/COFFEE PLUM (FLACOURTIA JANGOMAS)
Panial is a short to medium tree having spines in the young branches belongs to the family Flacourtiaceae. Flowers appear during April-May and fruits are harvested in August-September. Ripe fruits are brown or brownish red in colour. It is consumed as fresh fruits but fruits have good potential for the preparation of Jam. A typical local practice is that after harvesting, the matured fruits are gently pressed in between the palms of both hand before consumption as fresh fruits.
JALPAI/INDIAN OLIVE (ELAEOCARPUS FLORIBUNDUS)
Jalpai belongs to the family Elaeocarpaceae, is a medium to tall tree which bears flowers during April-May and fruits mature for harvest in August to October, Fruits are greenish in colour, single seeded and the shape resembles to olive fruit. Matured fruits are mainly used for the preparation of pickles and chutney. Considering their importance, it is urgently necessary to take initiatives for standardizing their package of practices as well as for exploring their product diversification.
OTHER MINOR FRUIT CROPS
Physico-chemical characteristics and utilization aspects of 26 different minor wild fruits of Sikkim were studied. These fruits are available round the year and have a great potential either for medicinal purposes or for producing different value added products or can be exploited for various non-fruit utilities like charcoal purpose, fuel wood etc. Such documentation will benefit the community and also preserves their cultural pride.
INTER CROPPING IN MANGO ORCHARD
The performance of elephant foot yam (Amorphopahllus paeoniifolius) sown in two different depth (10,15 cm) grown as intercrop with mango spaced at 6×6 m and 8×8 m revealed that under terai zone of West Bengal elephant foot yam yielded highest when sown at a depth of 10 cm and inter cropped with mango spaced at 8×8m.
Out of sixteen different treatments using different concentrations and combination of NAA and MH on post harvest life of potato dipping in NAA 2000 ppm for 30 minutes was considered best in reducing physiological loss in weight and percentage of rotting and sprouting of tubers for a period of 90 days.
Six popular local ginger genotypes of six districts of North Bengal was collected to estimate the quality parameters of their rhizome. It was found that selection- 2 is highest in yield, selection- 5 is suitable for dried and bleached ginger as it possesses highest dry matter content and lowest crude fiber content, with higher yield. Selection – 4 is most suitable for its oleoresin content.
The investigation on the suitability of some post harvest treatment combinations for better shelf life of green chilli revealed that treatment with GA3@150 ppm and packaging with LDPE of 100 gauge having 5% perforation and kept at 6-8OC temperature with 75% R.H. was most effective and suitable for increasing the shelf life of chilli having less effect in quality in respect to less physiological loss in weight, highest green colour retention and highest ascorbic acid content. When chemicals are not available the harvested fresh fruits can be stored after wrapping with PVC or LDPE and should be kept within cold condition (6-8OC temperature with 75%R.H.) for better shelf life.
