In this study, the parameters were optimized for processing of fruit juice powder by spray-dried and encapsulation to increase the bioavailability of vitamin C content. Fruits like lemon were selected to produce the fruit juice powder which provides a high content of vitamin C. Maltodextrin is a carrier material that is used in spray drying techniques at different levels of concentration like 15%, 20% and 25% to coat the fruit juices, reduce stickiness, and produce large quantities of fruit juice powders. In this method, the inlet temperatures ranged from 160ºC to 190ºC while outlet temperatures between 90ºC to 110ºC. Response Surface Methodology (RSM) and Artificial Neural Network (ANN) techniques were used to standardize the method for encapsulating the spray dried fruit juice powder. The physicochemical properties of spray-dried fruit juice powders were analyzed to enhance the nutritional content as well as shelf life. The yield of spray-dried lemon juice powder ranged from 121.56 g to 221.72 g, depending on the maltodextrin concentration. Spray-dried lemon juice powder contains 4.7 % to 5.7 % of moisture, 0.2141 aw to 0.2795 aw of water activity, 14.28 % to 17.64 % of hygroscopicity, 91.23 g/100g to 93.26 g/100g of carbohydrates, 138.32 mg/100g to 192.43 mg/100g of vitamin C, 96.54 (%RSA) to 128.62 (%RSA) of antioxidant activity respectively. The spray dried fruits juice powders were standardized by using RSM and ANN.
Agroforestry is one of the sustainable land management techniques, involving a combination of different agricultural, horticultural, and forestry practices to maximize the productivity and sustainability of land. In disadvantaged locations such as char lands, a well-planned interacting land use system incorporating woody perennials in line with the farmers' needs can lead to a successful and sustainable farming system to dwindle poverty and eventually improve food security. Agroforestry practices can serve this purpose in developing an agro-based economy like Bangladesh (BD). This study, therefore, is undertaken to reveal the farmer’s knowledge of agroforestry practice, and willingness to practice agroforestry and to examine the economic benefits of adoption of agroforestry. Following the multistage random sampling technique, a total of 240 farm households were selected from certain char areas of the Mymensingh (MS), Jamalpur (JP), and Sherpur (SP) districts of BD. The socioeconomic characteristics of sample farmers were explored in terms of age, education, gender, farm experience, land ownership, etc. Farmers’ knowledge, willingness, and adoption level of agroforestry were also examined. The majority of the farmers in the survey are aware of agroforestry practices (65%), but just a handful have actually used them. The farmers who adopted agroforestry practices or are interested to adopt, expect support (cash or kind) from the project or government. The tree species under agroforestry include Akashi, Eucalyptus, Mahogani, Mango, Jackfruit, Guava, Lemon, and Coconut. Financial or investment analysis of agroforestry adoption was done for several combinations of trees and vegetables.
Efficacy of bio-pesticides and mechanical barriers for eco-friendly management of banana against scarring beetle were evaluated in two field experiments at Bhola Paswan Shastri Agricultural College, Purnea, Bihar during 2014 to 2017. Neem seed kernel powder @ 15 g per banana whorl was found most effective against banana scaring beetle among all evaluated bio-pesticides and lower down the pest population (13.63 /plant) as compare to control (63.84/plant). This treatment showed lowest number of scars (13.43 scars/20cm2 area of banana) as compare to control (66.72 scars/20cm2 area of banana). It was also found effective and perform better in enhancement of number of hands/bunch (7.44), number of fingers/hand (16.60) and yield/plant or bunch weight (19.43 Kg). For the assessment of different mechanical barriers for eco-friendly management of banana scaring beetle, another experiment was conducted for three consecutive years at same location. In this experiment sprayed neem oil (azadirachtin 0.1%) along with 17 GSM polypropylene bags which acted as mechanical barrier for the new flower of banana just before/during opening of flower. It was found most effective in reducing scarring beetle population (5.91/plant) as compare to control (62.25/plant). This treatment showed lowest infestation (scars) (2.79 scars/20cm2 area of banana) as compare to control (62.78 scars/20cm2 area of banana) and also produced highest bunch weight (24.56 kg). It also enhanced fingers per hand (7.84) as well as number of hands (17.66) per bunch. Scarring beetle infested fruits lost their marketability due to partial or complete damage and fetched very low market price. Earlier it was considered as minor pest and farmers were unaware about its prevalence and eco-friendly management regarding this emerging pest. Present investigations for eco-friendly management by using bio-pesticides and timing of application of mechanical barriers helps farmers in reducing the pest population economically.
The present investigation on “Performance of macro-propagated and sucker grown plants of banana cvs. Jahaji (AAA) and Barjahaji (AAA)” was carried out at the Horticulture Experimental Farm, Assam Agricultural University, Jorhat during the year 2017-18 and 2018-19, respectively. The main objective was to see the comparative performance of macro-propagated and sucker grown plants of banana with respect of growth, yield and yield attributing characters of banana. The present experiment was laid out in factorial RBD with five replications and with two factors with two levels. The first factor consist two two levels namely ahaji and Barjahaji cultivars. The observations were recorded on yield and yield attributing characterstics/parameters. Quality parameters such as total sugars (16.96 %), reducing sugar (8.00 %), non-reducing sugars (8.21 %), TSS (20.64 º Brix), soluble fruit fibre (187.84 mg/100g) were found highest in the macro-propagated plantlets of Jahaji and the lowest mortality was found in (0.4%). Macro-propagated plantlets perform better in the field than suckers in all parameters of growth and yield. Negligible infestation of pest-diseases was observed in macro-propagated plants. Jahaji cultivar were superior to Barjahaji in the growth and yield attributes. Macro-propagated plants of Jahaji are best for cultivation in the North-Eastern region. During the first year and second year of the investigation macro-propagated plants were found best among all the treatments with respect to growth, yield and quality attributing characters. Field performance of macro propagated plantlets is better than conventional suckers . The occurrence of disease-pests is very less in case of macro-propagated banana plants. Macro-propagated plants are tolerance against insect-pests and diseases.
Mango is an important commercially farmed fruit crop and it is very popular due to its wide range of adaptability and high nutritive content. In order to understand the economics of mango production and the challenges faced by growers in production, the current study was carried out in the Kalahandi area of Odisha state of India. The study used a multi-stage sampling design with a 60-person sample size. Its information was gathered for 2021-22. Use a straightforward cost-return calculation to calculate the cost and profit of mango farming. The growers' challenges with mango production and marketing were ranked using the percentage method. Mango cultivation costs per quintal were calculated to be Rs. 1167.43, while per-hectare gross returns were, on average, Rs. 303944.67. The overall output-input ratio was 2.14, which is greater than unity and showed that mango production was a successful business. Lack of knowledge about high-yielding mango varieties, the issue of high temperatures, the problem of unavailability of transportation in sick, heavy rains, winds, and hailstones during flowering and fruit development stages, lack of extension services, and a lack of storage facilities near the growing area were among the production and marketing challenges faced by mango growers. The findings are in line with those of Yadav et al. (2010) who identified fruit drop as one of the major restrictions on mango output.
