Several empirical studies have assessed the impacts of transgenic crops on farms and overall in industrialized and developing nations, although there is significant opposition in the larger audience. Particularly, questions have been raised over the environmental, medical, and social impacts of transgenic crops in developing nations. By examining the consequences of insect-resistant transgenic cotton in India and drawing on several years' worth of data, this study fills in some of these knowledge gaps. The findings show that Bt technology is quite popular in India. By reducing their use of pesticides, increasing their yields, and increasing their profitability, adopting farmers have experienced tremendous gains. These results, which are based on a distinctive dataset, extend and confirm earlier research on the effects of Bt cotton in India and other poor nations. The majorities of growers were in favour of growing bt cotton and intended to continue doing so in the future. They believed that the intense bt cotton production would have significant social, economic, environmental, ethical, and biosafety ramifications in the near future. This data on bt cotton growers' perceptions and experiences will help researchers, extension workers, and policymakers develop effective strategies for both current bt cotton and upcoming transgenic crops.
The study was conducted in College of Horticulture, Venkataramannagudem, and College of Horticulture, Anantharajupeta, Dr.YSRHU, Venkataramannagudem in Andhra Pradesh state. The data collected from the graduates of two constituent colleges. Thus total 120 respondents were selected by using random sampling method. The majority of respondents were female, having rural background and had medium annual income ranged from Rs.1,51,832/- to 9,42,835/-, with marginal land holding. Majority of the respondent parents were in government service. Most of the respondents secured first class during their graduation with low participation in extra curricular activities. Majority of the respondents had medium level of decision making ability, achievement motivation, hortibussiness anxiety, innovativeness and risk orientation. Majority of respondents had medium level of personal entrepreneurship capability, sensitizations, and medium level of interest in studying the hortipreneurial concepts and medium level of tendency ie, level of inclination or likeliness towards hortipreneurship and they were having favorable attitude towards hortipreneurship.
The sustained rice yield plays an important role in the country’s GDP. Nowadays the key factors for enhanced growth and optimized yield of rice are often related to an appropriate crop establishment method (CEM), efficient nutrient fertilizer management (NFL), and sensible weed management practice (WMP). And therefore, the prime objective of this study was to standardize the CEM, NFL and WMP for sustained the optimized growth and yield of hybrid rice. The results disclosed that puddled transplanting rice (TPR) significantly enhanced rhizospheric and phyllospheric growth (plant height, tillers m-2, DMP, CGR, LAI, LAD, root volume and root biomass) and produced a significantly higher yield than un-puddled transplanting rice (UTPR) and dry direct seeding rice (DDSR). Application of 100% NFL registered the better growth with sustained yields though remained statistically identical with 125% NFL and both showed significant superiority over 75% NFL applied to the crop. However, herbicide layering (CW) of bispyribac-sodium 20g a.i. + pyrozosulfuron 20g a.i. was sprayed at 20 DAS/T in rice field had effectively controlled the weed flora associated though produced slightly a lesser yield productivity when compared to weed-free (HW) and both exhibited the maximum phyllospheric and rhizospheric growth with sustained yield over other two WMPs nonetheless failed to prove more remunerative than brown manuring (BM).
The study was carried out to evaluate the fumigant and repellent effect of Ocimum basilicum and Jasminum grandiflorum essential oils against Rhyzopertha dominica and Tribolium castaneum. Both tested essential oils had fumigant and repellent effect. For T. castaneum the highest concentration 0.24 mg/cm2 basil absolute had the lowest repellency with 65% while by basil oil was 82.5%, repellency. Jasmine absolute achieved the highest repellency at concentration of 0.12 mg/cm2 with 95% repellency. R. domenica was considerably more susceptible than T. castaneum in fumigant experiment. For R. dominica after 3 h basil oil had the strongest fumigant effect, with LC50 value 0.11 mg/cm3 while after 6 h basil oil had the strongest fumigant effect with LC50 value 0.07 mg/cm3. Based on LT50 Jasmine absolute seemed to be the most toxic material compared with the other materials used at the concentration of 0.4 mg/cm3, While against R. dominica calculated at four different concentration using fumigation method at the highest concentration (2.0 g/cm3) basil absolute had the strongest effect with LT50 of 2.15 h. The study also studied the chemical composition of tested essential oils and decleared that, acetic acid had the highest concentration with 15.951% for jasmine absolute and linalool is the main component in basil absolute with 46.345%, while Linalool was the main component in basil oil with 54.8%.
Urban greenery with the help of trees is the best and only method for lowering air pollution because the leaves of the trees absorb particulate matter, gases (such as sulphur oxides and nitrogen oxides), and metals. The ascorbic acid concentration, total chlorophyll content, leaf extract pH, and relative water content of 10 commonly found urban trees were assessed in the current study to determine their Air Pollution Tolerance Index (APTI) values. The study was taken up in three different urban localities, viz., control zone, heavy traffic zone and industrial zone in Coimbatore urban area of Western Tamil Nadu, India during the year 2021 – 22 under three different seasons namely summer, winter and rainy seasons. It was revealed that Thespesia populnea, Polyalthia longifolia and Delonix regia were outstanding tree species with high APTI value, which will perform best in urban air pollution condition. The remaining 7 tree species were categorized into good tolerant and moderate tolerant tree species, which can be used as 2nd and 3rd tier tree retardant rather than separate plantation programme in urban cities. This highly tolerant tree species in urban localities will not only helps in reducing the air pollution level, but also acts as a barrier as environmental protector.
