A face-to-face semi-structured questionnaire survey was carried out in 60 households of straw burning, and 60 households of straw incorporation to find out straw management practices adopted by farmers, their motive behind choosing those practices and timing of carrying out those practices. Farmers practicing those straw management practices for at least five years was considered as final respondent. Respondents were selected by using purposive sampling technique. Survey was carried out in six places of Rupandehi district where the problem of rice residue burning is severe mainly due to the use of combine harvesters in rice and wheat. Study resulted soil fertility enhancement as the primary reason behind both straw burning practice as well as straw incorporation practice adopted by farmers. Timing of rice straw burning was within 1 week of harvesting rice by majority of farmers. Timing of soil incorporation of rice straw followed by majority of farmers was 8-12 days after harvesting rice. Straw burning results the nutrients imbalance and creates environmental pollution. So, soil incorporation of rice straw is suggested to return nutrients back to the soil.","PeriodicalId":89696,"journal":{"name":"Journal of the Institute of Agriculture and Animal Science","volume":"51 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-08-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"75817713","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}

Similarly comparative efficacy of five fungicides viz. Copper Oxychloride 50% WP, Carbendazim 50% WP, Metalaxyl 8% WP + Mancozeb 64 % WP, Carboxin 37.5% WS + Thiram 37.5% WS and Hexaconazole 5% EC at four different concentration of 50 ppm, 100 ppm, 200 ppm and 500 ppm was tested using poisoned food technique. The experiment was arranged in a completely randomized design with three replications for each treatment and a control. Trichoderma viride and Trichoderma harzianum exhibited 66.64% and 62.32% growth inhibition respectively against Pestalotiopsis theae. Growth inhibition by fungicides ranged from 35% to 100%. Hexaconazole exhibited complete mycelial growth inhibition (100%) regardless of concentration. This complete inhibition (100%) in colony growth was recorded at 200 ppm and 500 ppm of Carboxin + Thiram and then in Metalaxyl + Mancozeb at 500 ppm. While least (35.62%) inhibition on mycelial growth of P. theae was observed with Copper Oxychloride at 50 ppm. There was significant reduction in colony growth of P. theae with each treatment at all concentration in comparison to control. This study indicated significant results by fungicides even at lower concentration and by both Trichoderma spp. This study established Trichoderma spp as a successful alternative and hence recommends use of an integrated approach with both effective fungicides at low concentration and bio-control agents in further managing grey leaf blight of tea plant after subsequent field trials.","PeriodicalId":89696,"journal":{"name":"Journal of the Institute of Agriculture and Animal Science","volume":"36 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-08-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"82531879","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}

This has created a huge problem for those farmers since they cannot store their own produce for a longer period of time thus facing problems in marketing. In order to inform the farmers with the best means of preservation of cut flowers so that they could fetch the good market price for their product. A lab experiment to study “effect of different floral preservatives on vase life of marigold (Tagetes erecta L)” was conducted at Campus of Live Sciences, Tulsipur, Dang in a factorial Completely Randomized Design. Altogether 9 treatments were used as: Distilled Water, Silver Nitrate (100 ppm), Malic Acid (2000 ppm), Citric Acid (2000 ppm), Salicylic Acid (1000 ppm), Gibberellic acid (50 ppm), Kinetin (50 ppm), Naphthalene Acetic Acid (50 ppm), Silver Nitrate (50 ppm) + Citric Acid (1000 ppm) + Gibberellic acid (25 ppm). Results showed that the use of floral preservatives affects the parameters like flower diameter, weight, post-harvest life, blackening of petals and sepals and water uptake. It has been observed that minimum change in weight for kinetin (19.39%), minimum change in diameter for gibberellic acid (4.18%), maximum postharvest life was for gibberellic acid (14.66 days), minimum neck bending for kinetin (33%), maximum water uptake for kinetin (4.38%) and minimum blackening for growth hormones. From this experiment we can conclude that growth hormones (kinetin (50ppm) and gibberellic acid (50ppm)) are suitable for postharvest handling and storage of marigold.","PeriodicalId":89696,"journal":{"name":"Journal of the Institute of Agriculture and Animal Science","volume":"44 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-08-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"75658775","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}

Trichoderma, free-living fungi, are successful antagonists with promising biocontrol potentials and can be used with chemicals and botanicals in the IDM approach to control various plant pathogenic fungi. So, the present experiment was conducted to evaluate the compatibility of Trichoderma harzianum with chemical fungicides and botanicals in in-vitro using a poisoned food technique. The experiment was conducted in a completely randomized design with three replications for each treatment at the central laboratory of the Institute of Agriculture and Animal Science, Lamjung, Nepal, and data were taken at different time intervals and analyzed. For fungicides, the maximum compatibility was found in Copper oxychloride at 100 ppm, and the highest inhibition (100%) was observed in Carbendazim + Mancozeb, Carbendazim, and Hexaconazole even in lower concentration (100 ppm). For botanicals, Azadirachta indica and Zingiber officinale enhanced T. harzianum, and the highest compatibility was observed at 10% leaves extract of Azadirachta indica with a growth inhibition percentage of -5.43% (Day 5). Aqueous extracts of tested botanicals were found compatible with T. harzianum, except for the Acorus calamus, Artemisia vulgaris, and Allium sativum.
