Introduction of dwarf wheat varieties coupled with intensive input (assured irrigation and fertilizers) use after Green Revolution led to complex problem of both grassy and broad leaved weeds. Weed management is very important for achieving higher wheat production. Mechanical, cultural, biological and chemical methods can be adopted for weed management in wheat. Due to industrialization, labour is becoming scarce and costly. Among these methods, chemical weed control is more efficient, less costly and less time consuming. Pre-emergence herbicides cannot control the late flushes of weeds especially, grassy weeds. Post emergence herbicides are very effective against weeds in wheat. However, herbicides are effective against some weed groups due to mode of action and they do not kill other weeds. To control other weeds, another herbicide is needed which involves more cost, time and labour. To overcome this, sequential application of herbicides, herbicidal mixtures and herbicidal combinations are used. The herbicidal combinations could be very effective against both grassy as well as broad leaved weeds and help to reduce cost, time and labour. Application herbicidal combinations viz. clodinafop + metsulfuron (vesta) 60 g ha-1, sulfosulfuron + metsulfuron (total) 32 g ha-1 and mesosulfuron + iodosulfuron (atlantis) 14.4 g ha-1 as well as tank mixture of pinoxaden + carfentrazone (50 + 20 g ha-1) is the best way for managing complex weed flora in wheat as of now. Modification in application method like tank mixture with micronutrients also have potential of increasing the weed control efficiency of herbicides and yield of wheat. To give precise and concise information weed management in wheat, his article reviews the latest herbicides recommended for weed management in wheat. Recent advances in herbicidal mixture, combinations and application techniques are also being included in this review.","PeriodicalId":418512,"journal":{"name":"Journal of Agriculture Research and Technology","volume":"107 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131747861","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}

Agriculture which includes forests and fisheries, is critical for food security, rural income, and other necessary items including energy, fiber and feed. Working at the landscape level with an ecosystem approach, including forests, fisheries, crops, and livestock systems, is critical for responding to and mitigating the effects of climate change. Farmers, fishermen, and forest-dependent people will need institutional and financial support to make shift to climate-smart agriculture. Agriculture is one of the most vulnerable sectors to climate change effects, it also accounts for 14 percent of global greenhouse gas emissions. Furthermore, agriculture is a major contributor to deforestation and land degradation, which account for another 17% of emissions. Management and governance strategies based on ecosystem concepts will be required for sustainable use of natural resources. Climate-smart agriculture is based on sustainable agricultural and rural development goals, if met will help to achieve the Millennium Development Goals (MDGs) of hunger reduction and better environmental management. Policies at the regional, national, and international level must be evaluated to better reflect the need for consistent and comprehensive approaches to agricultural development, climate change and food security protection. The main goal of developing nations should be to achieve the four elements of food security (availability and access to food, food with nutrition, and food supply stability). Climate financing is required to ensure that investments are sufficient to enable the transition to climate-smart agriculture. Climate-smart agriculture tools and information must be improved and shared at a greater extent.","PeriodicalId":418512,"journal":{"name":"Journal of Agriculture Research and Technology","volume":"63 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131240303","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}

Crop coefficient (Kc)-based estimation of crop evapotranspiration is most commonly used methods for irrigation water management. However, crop coefficient approach used for estimation ETc using the generalized crop coefficients mentioned in Irrigation and Drainage Paper No. 56 of the Food and Agricultural Organization of the United Nations can contribute to crop evapotranspiration estimates that are substantially different from actual crop evapotranspiration. The colinear relationship between the crop coefficient curve and a satellitederived Normalized Difference Vegetation Index (NDVI) showed potential for modeling a crop coefficient as a function of the NDVI, which is also one among the methods used for estimation of ETc in irrigation water management. The present study was conducted with objectives to present the techniques and procedures to develop and estimates Kc based on vegetation index (NDVI) extracted from satellite data. The relationships between and NDVI and crop coefficients (Kc) of wheat and chickpea for corresponding months were developed. The regression models developed are: (Kc) NDVI = 6.3268*NDVI-1.4207 for wheat and (Kc) NDVI = 5.7866 * NDVI-1.6699 for chickpea. The models showed strong relationships with R2= 0.86 and R2=0.84 for wheat and chickpea, respectively. The model and techniques to develop and estimate crop coefficients can be used in other regions in the global, and hence estimate crop evapotranspiration. The crop coefficients (Kc) estimated based on NDVI are useful for irrigation scheduling, evaluating irrigation performance, irrigation water management, and estimation of water use efficiency.","PeriodicalId":418512,"journal":{"name":"Journal of Agriculture Research and Technology","volume":"2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133720569","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}
