    Problems and prospects of paddy straw management technologies in Bathinda district
    (Punjab Agricultural University, Ludhiana, 2020) Amanjot Kaur; Prabhjot Kaur
    The study entitled “Problems and prospects of paddy straw management technologies in Bathinda district” was undertaken to study the status and prospects of paddy straw management technologies and problems faced by farmers in the adoption of paddy technologies. The study was conducted in Bathinda district of Punjab. All the nine blocks of Bathinda district were selected and from each block one village was selected randomly, so nine villages were selected for the study. Total of 135 respondents comprising 15 respondents were selected randomly from each village for the purpose of study. Interview schedule was prepared and data was collected personally by interviewing respondents. The results of the study revealed that majority of the respondents were of the middle age group (41-53 years), had education up to matriculate and having small (2.5-5 acres) operational land holding. Majority of the respondents had low extension contacts and medium category of mass media exposure, innovativeness and risk bearing capacity. Respondents had awareness regarding happy seeder, baler, super straw management system, chopper-cum-spreader but not aware about cutter-cum-spreader, use of straw for composting. Majority of respondents adopted happy seeder in 2017, baler, super straw management system, mulcher and chopper-cumspreader in 2018. In 2019, majority of respondents adopted baler technology for managing paddy straw. Area under baler and mulcher in future will be increase by respondents. Problems of insect-pest, rodents were increased after adopting technologies like happy seeder, chopper-cum-spreader and mulcher. Technologies like baler, mulcher and chopper-cumspreader were not available to majority of respondents on time.

    Fungal flora associated with rice grain discoloration in Punjab and it’s management
    (Punjab Agricultural University, Ludhiana, 2016) Amanjot Kaur; Jain, Sandeep
    Paddy discoloration causes serious losses in terms of quality and quantity leading to procurement problems. Paddy samples were collected from different districts of Punjab during the Kharif 2013 and 2014. Analysis of paddy samples collected during the year 2013 and 2014 revealed that incidence and severity of discoloration was higher in 2013 as compared to 2014. The rice and basmati rice cultivars were found to be affected by discoloration to varying extent. Fungi namely, Drechslera oryzae, Alternaria alternata, Fusarium moniliforme, Curvularia lunata, Aspergillus flavus, Aspergillus niger, Chaetomium spp., Nigrospora spp. and Rhizophus spp. were identified to be associated with the diseased samples. Among these fungi, Fusarium moniliforme, Drechslera oryzae, Alternaria alternata and Curvularia lunata were the most predominant. The discoloration affected the grain weight, seed germination, total seedling length and seedling vigour. Milk and dough stages of rice were found to be critical on which simulated rain caused higher discoloration. Recently released rice varieties like PR 124, PR 123 and Punjab Basmati 3 were found to be highly susceptible under artificial inoculation conditions. Under in vitro conditions propiconazole and tebuconazole provided maximum inhibition of growth of all the fungi. Carbendazim was effective only against Fusarium moniliforme and ineffective against rest of the fungi. In field evaluation of fungicides, the spray schedule comprising of propiconazole – propiconazole – tebuconazole given at boot stage followed by 15 days after boot stage and at soft dough stage was found to be highly effective in checking the grain discoloration.
