Face-to-face structured surveys from January 2022 to March 2023 were conducted in Mirpur Upazila (Sub-district) from Kushtia and Gangachara Upazila from Rangpur districts of Bangladesh. Result: Only 46.4% of the farmers are willing to stop tobacco cultivation. The key determinants for their willingness to stop growing tobacco are education level, tobacco cultivation experience, incentives and organizational participation of the tobacco farmers. In the farmer’s view, maize, mustard, potatoes and lentils are the most suitable food crops to replace tobacco. To shift tobacco farmers to growing food crops, the Government should increase the farmers’ educational level and offer inputs, loans and other incentives to promote alternate crops like maize, mustard, potato and lentil.","PeriodicalId":503872,"journal":{"name":"Agricultural Science Digest - A Research Journal","volume":"37 10","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-05-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140971337","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Conventionally, groundnut cultivation also need good amount of commercial nitrogen fertilizers which are found to be not efficiently and effectively utilized by the plants, also lost due to leaching and so, causing severe ecological damage. However, our study of priming groundnut seeds with nanofertilizers have reduced the dosage of fertilizers as well as increased the yields. Methods: A two-year field experiment (2020-2021) was carried out to evaluate the effect of nano fertilizers (NF) (phosphorus, zinc, and iron) seed priming and NF foliar spray on the growth, yield, and seed quality characteristics of groundnut var TG-37 A. Groundnut was chosen as the testcrop and seeds were primed with nanofertilizers as well as standing crop is foliar sprayed with nanofertilizer at pre-flowering stage. The effect of nanofertilizers on test crop was evaluated on seed germination, seedling vigor, plant growth, flowering, chlorophyll content, pod yield, oil content and protein content. Result: The results indicated that in both the years, NF seed primingandfoliar sprays treatments showed higher seed germination and seedling vigor aided in early establishment in soil, which manifested by higher plant height, early flowering, higher leaf chlorophyll content, 100-seed weight and shelling percentage. Pod yield per plant was 30.1% and 33.0% higher in 2020 and 2021, respectively, as compared to the control. In both years, the application of nano fertilizers considerably boosted the oil and protein content compared to the control (31.5% and 28.9% for oil, 33.1% and 30.0% for protein). Thus, it is concluded that nano-fertilizers considerably improved growth, yield and quality of groundnut.","PeriodicalId":503872,"journal":{"name":"Agricultural Science Digest - A Research Journal","volume":"2 3","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-05-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140967285","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Phototactic responses were also observed for IR (730 nm) and UV (365 nm) at different durations (2, 6, 12, 24 h). Result: The rate of insect attraction was different for different wavelengths of light. The duration of the intended light also showed a positive response to the attraction rate of the insect, as in every case, 24 hours of duration showed the maximum attraction. The green light showed the highest attraction rate (77.78%) at an intensity of 50 lux for 24 h duration, followed by blue (74.44%) and red (65.56%) light at an intensity of 25 lux for 24 h duration (each). UV (65.56%) also showed a positive attraction at 24 h duration, but IR (52.22%) showed the least attraction.

Of the different insect pests attacking rice, brown planthopper, BPH, Nilaparvata lugens (Stål) is an important sucking pest causing upto 100% yield losses. Host plant resistance is the most important method in keeping BPH under control and understanding the underlying mechanisms of resistance is necessary to breed the resistant varieties with desirable characters. Methods: Selected EMS mutant lines of Nagina22 (N22) variety, which were previously mass screened under controlled greenhouse conditions were assessed for their antixenosis mechanism to brown planthopper feeding by measuring probing marks and honeydew excretion area by following standard procedures and statistical analysis was done by using Statistix 8.1 software. Result: Both the brown planthopper nymphs and adults probed more in the resistant mutants compared to the susceptible mutants whereas the BPH adults probed more times (24.4) compared to the nymphs (22.2). The recorded honeydew excretion area by the resistant mutants was lower than that of susceptible mutants. In general, the BPH adults fed more and excreted more honeydew (79.5 mm2) compared to the nymphs (59.0 mm2). The damage score has a negative correlation with the probing marks of adults (-0.207) and nymphs (-0.411); and a positive correlation with honeydew excretion of adults (0.547) and nymphs (0.200). In this study, the EMS N22 mutants resistant to BPH, with a greater number of probing marks and less honeydew excretion area can serve as best donors in the breeding programmes to develop brown planthopper resistant varieties.\u0000","PeriodicalId":503872,"journal":{"name":"Agricultural Science Digest - A Research Journal","volume":" 20","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-05-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140990989","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The productivity of intercropping systems can be increased by using the right planting geometry, together with effective nutrition and water management. Methods: The experiment was carried out at the Water Management Research Unit in Vellanikkara. The experiment was set up using a randomised block design that was triple duplicated. Two different planting geometries, normal row planting and paired row planting, three nutrient levels, or 100, 75 and 50% of the NPK recommendation for both crops as fertigation and two irrigation levels, or 100% Epan and 75% Epan, made up the treatments. Result: The yield of intercropped chilli was 41% lower than that of chilli grown as a pure crop, according to crop performance under the intercropping and pure crop systems. However, intercropping increased amaranth production by 17% compared to pure crop. Amaranth receives nutrients from the fertigation supplied to the chilli crop in addition to the fertigation of amaranth. Because of this, intercropped amaranth produced more dry matter; absorbed more nutrients and produced a better yield. Gross return, net return and B:C ratio was used to evaluate the economic advantage of the intercropping system. In comparison to pure crops of chilli (Rs.197716) and amaranth (Rs.24548), the net return of the chilli-amaranth intercropping system (Rs. 428212) was 116 per cent higher and 164 per cent higher, respectively.
