Abstract/ Executive Summary:

Background and Objectives: Due to huge demand and availability of Banana, innovative cost effective method is necessary to promote and smoothen the banana production among farmers commercially mitigating the demand. Method and Materials: In this study, we feed cow dung mixture along with Urea, TSP, MoP, water to the distal part of rachis after cutting down male bud as soon as the female flowers matured into fruits (T1). The effect of this method was then compared with two control groups; one with the same strategy except fertilizer applied on root following ring method (C1, Positive control) and another was male flower untouched without applying fertilizer on rachis or root (C2, Negative control). Results and Conclusion: T1 showed more than double increase in length than controls. In the same way, in case of shape (diameter), T1 (0.46 cm) showed twice as better growth in the C1 (0.22 cm) and C2 (0.18 cm). Trend analysis showed the test group T1 curve is much steeper than the control groups suggesting faster growth rate than the other two. Finally, the cost of fertilizers for T1 per plant was estimated 0.091 USD while for positive control C1 it was 2.9 USD. This study shows an approach to be effective and economic comparing to traditional method of fertilizer application, which can be adapted as a new method of banana production.

Location: Suborno Agro-Based Initiative (SABI), Noakhali, Bangladesh.

Start Date: 00-01-2017

End Date: 00-03-2018

Program Area: Crop-Soil-Water Management

Commodity: Banana, Bio fertilizer

Objectives:

The present experiment has showed a new improvised method to develop the size and shape of banana fingers with minimal cost and labor. This new method will help the farmers to produce more bananas with minimum cost and labor. Farmers can be benefitted economically and will be able to mitigate public demands. This method maintains the main principle of agricultural production is less input with more outputs.

Methodology:

The study was conducted at a commercial farm named Suborno Agro-Based Initiative (SABI), Noakhali, Bangladesh. The study was conducted from January, 2017 to March, 2018. The experiment was laid out in a Completely Randomized Block Design (CRBD) consisted of three treatments and three replications.

2.2 Treatment: 2.2.1 T1: Cowdung (250 g) +Urea (85g) +TSP (70g) +MOP (65g) +20ml water; Removal of male bud as soon as female flower transform into fruits and application of the mixture on slanted rachis. For T1 the rachis of the distal end of the bunch was excised along with the male bud giving a slanted cut immediately after all the pistillate flowers had formed into fruits. 250 g Cow dung was mixed with 20 ml water to form slurry with 85g of urea, 70g of TSP, and 65 g of MOP. The blend was then placed in a polythene bag and tied carefully to dip the excised rachis into the slurry.

2.3 Controls: 2.3.1 C1: Control group: Urea (3kg) +TSP (3kg) +MOP (2.5kg) + Cowdung (5kg), Removal of male bud as soon as female flower transform into fruits and application of the mixture on tree root. In control group C1, when the female flowers transformed into fruits male flower were cut down. Cowdung with an amount of 5kg were placed at the bottom of plant in ring method. Urea (3kg) +TSP (3kg) + MOP (2.5kg) were mixed and applied to the bottom of plant along with cow dung following the same method. 2.3.2 C2: Control group: Retention of male bud till harvest without fertilizer application on rachis or root. In the plants of control group C2, the male bud retain in rachis till harvest without any modification or application of any fertilizer either on rachis or plant root. For all three groups, initial data for the banana finger length (cm), finger diameter (cm) and weight of fingers (g) was collected as soon as the female flower matured into fruits and data collection continued for two weeks with seven day interval until banana ripen. 2.4 Data Collection: The data were collected every week after treating. The data were collected in the morning and very carefully to avoid any destruction to fruits and plants. 2.4.1 Size: The size of the banana was measured in centimeters by measuring tape.

2.4.3 Cost: The total cost (input) was calculated after harvesting for all three groups. 2.5 Statistical Analysis: The data were put into the computer for statistical analyses. The SPSS computer program was used for analyzing the data. Various descriptive statistical measures such as range, frequency, number, % age, mean, standard deviation (SD), coefficient of variation (CV), R2 and rank order were used for categorization and describing the variables.

Achievement/Findings:

This study discovered a new method that can be beneficial for the farmers to produce more production with less cost. In developing country like Bangladesh, have more limitation in Agriculture because of huge population. So, more production is needed from less land and capital. The present study need less fertilizers and labor and give bigger sized and shaped banana. In the market of Bangladesh the demand of bigger sized and shaped banana is high than others. This study will help the researchers to uncover the critical areas of plant modifications and horticulture that many researchers were not able to explore. Thus a new method on banana production may be arrived at.
