The present investigation was undertaken to evaluate some indigenous banana genotypes of Odisha. Eight indigenous banana genotypes of Odisha were evaluated in a randomized block design with three replication during the year 2018-19. Observations were recorded on growth parameters, yield attributing traits and quality parameters. Analysis of variance indicated significant differences among the genotypes in respect of all the characters studied. The results revealed that maximum pseudostem height of 312.80 cm and girthof 73.40 cm were recorded in Koraput Champa at the time of shooting. The highest number of suckers was produced by Banua (8.46) whereas highest number of leaves at the time of shooting was produced by Champa (12.13). Comparatively early shooting and harvesting was obtained in Singapuri (255.33 and 333.33 days) whereas late shooting and harvesting was recorded in Kathia Champa(379.00 and 451.33 days). Regarding yield parameters highest bunch weight (14.50 kg), bunch length (61.33 cm), bunch girth (88.35 cm), finger weight (129.40 g), finger girth (16.76 cm) and yield (36.26 t/ha) were obtained from Koraput Champa. However Singapuri recorded the maximum finger length of 22.97 cm. With respect to quality parameters highest TSS, reducing sugar and total sugar were recorded in Koraput Champa. Regarding shelf life result revealed that Banua recorded the maximum shelf life of 9.23 days and lowest shelf life was recorded in Mazapuri (5.16 days). Keeping the observations in mind Koraput Champa was found to be superior in all aspects.
The present study was undertaken to evaluate five cultivars of banana (Musa sp.) belonging to different genomic groups (AAB and ABB) for growth, yield and quality attributes. From the evaluation of the data for growth, yield and quality parameters, it was evident that among all the genotypes, the maximum pseudostem height (352.3 cm) was recorded in Budubale, whereas, NRCB Selection-10 recorded the highest pseudostem girth (69.4 cm), number of suckers (8.6), and number of functional leaves (14.6) at shooting stage. The earliest shooting and fruit maturity (216.1 and 297.4 days respectively) were observed in BRS Selection Popoulu, whereas, late shooting and fruit maturity (289.6 and 390.1days respectively) were recorded in Budubale. Regarding yield attributes, the maximum bunch weight (20.4 Kg), bunch length (66.6 cm), number of hands per bunch (12.1), number of fingers per bunch (171.2) and yield per hectare (51 tonnes) were recorded in genotype NRCB Selection-10. However, bunch girth (160.1 cm), finger girth (20.0 cm) and weight of finger (264.6 g) were highest in BRS Selection Popoulu. In the AAB genomic group, Popoulu and Manjeri Nendran registered 62.13% and 34.45% yield increase over the check Nendran respectively. In the ABB genomic group, NRCB Selection-10 recorded 40.68% yield increase over the check Budubale. With respect to the quality parameters like TSS, reducing sugar and total sugar content, the genotype, Manjeri Nendran was found to be superior among all the genotypes. On the basis of results obtained in the present investigation, NRCB Selection-10 recorded the highest yield which was at par with BRS Selection Popoulu. The maximum net return of Rs. 392000/ha and B:C ratio of 2.78 was recorded in NRCB Selection-10 against the B:C ratio of 1.89 in BRS Selection Popoulu.
A field experiment was carried out during 2018-19 at Precision Farming Development Centre, Bhubaneswar, Odisha to find out the effect of fertigation scheduling on vegetative and reproductive growth behaviour of guava var. Arka Amulya under eastern coastal plain zone of India. Three levels of fertilizer dose (100%, 80%, 60% RDF) in combination with three levels of fertigation frequency (monthly, bimonthly, quarterly) and control as 100% RDF in soil application was evaluated employing Factorial Randomized Block Design and replicated thrice. The result of the investigation revealed that both the vegetative and reproductive characters were significantly influenced by use of different fertilizer dozes at different frequencies. Among the treatment combination 100% RDF at monthly interval resulted in maximum vegetative growth, viz. plant girth (0.90 cm), canopy volume (7.79 m 3 ), leaf area (50.42 cm 2 ), number of tertiary shoots (58.25), tertiary shoot girth (2.16 cm) and number of leaves per tertiary shoots (18.00) while canopy volume, leaf area, girth of primary branch and tertiary shoot remain statistically at par with 80% RDF at monthly fertigation. Also the maximum tertiary shoot length (16cm) was observed in 80% RDF at monthly interval. Similarly the reproductive characters like number of reproductive shoots (31.50), number of flowers (14.81), fruit set (79.49%) and fruit retention (45.60%) were highest in 80% RDF at monthly interval. Therefore, considering the positive effect on plant, 80% RDF at monthly interval is considered to be the best from economic point of view.
