Development of package of practices for mechanized transplanting in rice under Cauvery delta zone of Tamil Nadu
A field study on development of package of practices for mechanized transplanting in rice was conducted at Tamil Nadu Rice Research Institute, Aduthurai during 2020-21. Six treatments viz., two age of seedling 15,21 days old seedlings, two time of planting viz., normal, and 15 days delayed planting, It was also compared with conventional transplanting with 25 days old seedling under normal and 15 days delayed time in randomized block design. Mat nursery was prepared for 8 row Yanmar transplanting machine. The result showed that mechanized transplanting with 15 days old seedling under normal planting of June planting recorded higher number of tillers (355/m2), No. of grains/panicle (162/panicle) and grain yield (5511 kg/ha) during normal time of planting. Delayed transplanting with 15 days resulted in decrease in grain yield. Delayed transplanting of rice beyond June 30th recorded reduction in yield varied from 361 to 1001 kg/ha. Higher net income (54506 ₹/ha ) and B:C ratio (2.2) was recorded in 15 days old seedling under mechanized transplanting under normal planting time of June.
Variability studies on morphological characteristics of seedling bael genotypes in the north-western plains of India
Bael (Aegle marmelos Correa) is one of the important indigenous fruit of India with high nutraceutical significance. The experiment was conducted to study variability based on morphological characteristics among seedling origin bael genotypes. A survey was undertaken during 2020-21 to 2021-22 in three districts of Jammu and Kashmir, Union territory of India. The study comprised of characterization and evaluation of seedling origin bael genotypes that were identified in Jammu, Samba and Kathua districts. Eighty seedling origin bael genotypes with two commercial cultivars from different areas were selected where the results revealed that maximum tree height (17.20 m) was recorded in JMU-Bael (Sel-50), trunk girth (63.40 cm) in JMU-Bael (Sel-32), tree spread in E-W (8.80 m) in JMU-Bael (Sel-48) and N-S (6.30 m) in JMU-Bael (Sel-54) and intermodal distance (7.00 cm) in JMU-Bael (Sel-68) compared with NB-5 and NB-9. The detected variation can be utilized in a future breeding program for improvement of Bael.
Standardizing the process parameters of encapsulated lemon juice powder
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.
Maximizing Productivity and Sustainability of Land through Agroforestry: Insights into Knowledge, Perceptions, and Economic Benefits
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.
Eco-friendly management of leaf and fruit scarring beetle (Basilepta spp., Colaspis spp.) by using bio-pesticides and mechanical barriers
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.
