The objective of the study was to identify stable, high-yielding and high-quality sugarcane varieties to meet the food and energy demands of India and to sustain the productivity. The study focused on the effects of genotype-by-environment (G × E) interaction on yield and quality parameters, and multivariate analyses, specifically AMMI and GGE biplot, were employed. Seventeen elite sugarcane genotypes along with standard Co 86032 were evaluated in RCBD with three replications at two environments of Tamil Nadu (Nellikuppam: coastal region, and Alapuram: drought-prone area) during 2019–2021 seasons as two plant and one ratoon crops. AMMI analysis of variance revealed that environmental factors and G × E interactions significantly influenced all the four traits under study, viz., sugar yield, cane yield, CCS per cent and sucrose per cent. AMMI analysis identified four entries, viz., Co 12009, Co 14002, Co 14005 and Co 18009 superior to sugar and cane yield, and among these Co 14002 was stable across environments and Co 12009 was moderately stable. Co 17003 was identified as superior and stable entry for quality parameters. GGE biplot analysis further supported these findings, with the first two principal components explaining significant proportions of total G + GE variation for each trait. Co 12009 and Co 14005 were highlighted as winning genotypes for CCS yield, with Co12009 showing moderate stability. Co 12009, Co 14002 and Co 14027 were identified as superior and stable high yielding varieties and Co 17003 as high-quality genotype across the locations. GGE biplot provided insights into the relationships among the test environments. Based on the comprehensive analysis sugarcane cultivars, Co 12009, Co 14002 and Co 14005 were identified for commercial cultivation considering their stability and superior performance across the various environments.</p></div>","PeriodicalId":781,"journal":{"name":"Sugar Tech","volume":"27 2","pages":"540 - 558"},"PeriodicalIF":1.8,"publicationDate":"2024-09-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143362224","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this sense, the adoption of alternative planting methods to the conventional one, based on billets, such as the use of presprouted seedlings (PSS), has been considered a promising approach. Nevertheless, remains unclear how billets and PSS of distinct origins, i.e. obtained either from individualized buds or in vitro culture, affect sugarcane yield potential under field conditions. Therefore, we aimed to improve our understanding on this issue by evaluating the effects these propagation materials on crop nutrient absorption at critical phenological phases. A field experiment was conducted during the plant-cane cycle aiming to assess the accumulation of aboveground biomass and nutrients at tillering (128 days after planting, DAP), grand growth (282 DAP) and ripening (381 DAP). Our results revealed that the absorption of macro (nitrogen, phosphorus, potassium, calcium, magnesium and sulfur) and micronutrients (boron, copper, manganese and zinc) across the whole growing season did not depend on propagation materials. This phenomenon occurred because both aboveground dry mass production and shoot nutrient concentration did not vary as a function of treatments. Accordingly, propagation materials of contrasting features, in terms of stored reserves and stage of root and canopy development, do not pose any effect on growth and nutrient acquisition capacities of sugarcane plants. There seems to be, hence, no clear reason to propose significant adjustments in fertilizer guidelines during field establishment with the adoption of PSS of distinct origins.</p></div>","PeriodicalId":781,"journal":{"name":"Sugar Tech","volume":"27 2","pages":"559 - 565"},"PeriodicalIF":1.8,"publicationDate":"2024-09-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143362225","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The implements association increased hourly fuel consumption during soil preparation, as observed in CT and CTI compared to MT, where only one implement (subsoiler) was used. In NT, we found the lowest hourly and operational fuel consumption. The highest total productivity and sugar production (TRS) were obtained with minimal soil management (MT).

For the last three hundred years, it has been an important source of sugar, particularly in Europe and other temperate regions of the world, but changes in modern agriculture, world trade and economics have led to a decline in the use of sugar beet as a raw material for sugar factories. As sugar is an important product and an important ingredient for many industries, sugar beet will continue to be grown in many countries for strategic reasons. Nevertheless, this plant has become an interesting source for many new byproducts and technologies. The sugar beet root not only has a sugar content of about 20%, but also contains an abundance of pectin, cellulose, hemicellulose and other materials that are used for the production of textiles and biodegradable materials such as bioplastics. Due to global warming and the rise in average temperatures in many regions of the world, the energy sector will rely on biofuels such as bioethanol and biogas. Many countries are acquiring automotive technology based on the use of ethanol. Biogas with a high methane content can be produced through the use of sugar beet fermentation technology. This is also an acceptable alternative and a way to move to more environmentally friendly energy sources. Many regions of the world have problems with saline soils. Since sugar beets has a high tolerance to salt, they can be grown on these soils to improve fertility and other soil properties and create a more suitable environment for plant and human life. The sugar beet grown on these soils can be used as animal feed or as a raw material for various industries to produce paper, bioplastics or biogas and ethanol. Byproducts of the sugar industry such as molasses and beet pulp can be used for several purposes. Molasses is an environmentally friendly product derived from sugar manufacturing process from beat and are being utilized for several byproducts. Intercropping sugar beet with other crops has many advantages. Sugar beet products as feed for dairy cows has increased the quantity and quality of milk. Sugar beet has found its place in the circular economy and in many new technological byproducts.

Data were collected through detailed questionnaires and in-depth interviews with farmers.

From the canopy reflectance data, differences were found between the reflectance spectral curves for both locations and among cultivars. The dendrograms of the vegetation indices could also discriminate the cultivars in the phase of maximum vegetative development and allow different groupings according to the production environments and the yield of each studied cultivar. Hyperspectral data have the potential to aid in the characterization of new sugarcane clones as a result from genetic improvement programs, and they can support studies on the use of remote sensors for the same purpose.</p></div>","PeriodicalId":781,"journal":{"name":"Sugar Tech","volume":"27 1","pages":"94 - 107"},"PeriodicalIF":1.8,"publicationDate":"2024-09-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143109160","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
