The research was conducted at Metahara Sugar Estate, Ethiopia (8° N latitude and 39° 52' E longitude) during the season of 2014/2015 on three soil types. Fourteen sugarcane genotypes were evaluated in a randomized complete block design with three replications to study association of characters influenced the final behavior of fourteen sugarcane genotypes regarding cane and sugar yield characters namely; number of tillers and millable cane, stalk height, stalk diameter and recoverable sucrose (%). The results indicated that genotypes CP 96 1252 and NCO 334 had shown superiority for cane and sugar yield per ha under medium soil. While, CPCL 02926 and VMC 96120 for cane yield CPCL 02 926 and CP 96 1252 for sugar yield under heavy soil; and B 52-298 and CP 04 1935 for cane yield and CPCL 02 926 and CP 04 1935 for sugar yield under light soil had shown superiority. Characters association results showed sugar yield was mainly determined by recoverable sucrose percent under heavy soil while it is by cane yield and its components number of tillers, milable stalks and plant height under medium and light soil types.
Comparative analysis of physiological characteristics and yield components in sugarcane cultivars
Field crops research, 2007
Sugarcane in an important crop due to the economic value of its products. Physiological characteristics and yield components of sugarcane were studied in three field-grown sugarcane cultivars B 63118, POJ 2878 and Ja 60-5. Three growth stages were identified: formative phase (until 140 DAP), grand growth (140-300 DAP) and maturity (after 300 DAP). Results indicated that cultivars showed contrasting yield mainly after 300 DAP. At ripening, the most productive cultivar (Ja 60-5) achieved higher leaf area, an optimum leaf area index for light interception, a high and stable net assimilation rate and an elevated leaf area and biomass duration. In addition, this cultivar showed the higher density and lower area of leaf sieve elements as compared with other, which could influence the high translocation rate (1.85 cm min À1 ) at 8 MAP. The higher efficiency of this process in Ja 60-5 might also be supported by a higher (15-25%) apparent free space of stem parenchyma as compared with POJ 2878 and B 63118. Our results suggest that Ja 60-5 reduced carbon partitioned to foliar respiration which led to a higher partitioning of sucrose to stems evidenced by a higher Pol%. #
Correlation Studies of Agronomic Traits for Higher Sugar Yield in Sugarcane
2012
Twelve sugarcane clones were used in this study. The analysis of variance revealed significant differences among genotypes for all the plant characters. Highest cane yield (144 t/ha) was recorded in clone NIA82-1026P5 and highest Pol % (20.82) and CCS % (16.45) were observed in CP84-1198. Correlation coefficient results indicated that cane yield was positively correlated with cane girth, weight per stool, sugar yield, tiller numbers and purity % whereas Pol % and CCS % showed negative correlation with cane yield. Sugar yield showed non significant correlation with cane girth.

Study on Morpho-Physiological Characters in Different Clones of Sugarcane (Saccharum officinarum L.)
2017
Sugarcane, an industrial crop was grown in an area of 50.32 l ha with a cane production of 356.56 Mt and a productivity of 70.86 t ha -1 in India during 2014-15. It occupied an area of 49,000 ha with a cane production of 3.67 Mt and a productivity of 75 t ha -1 in the state of Telangana in 2014-15. India ranks second in terms of area and per hectare productivity. Sugarcane being a C4 plant is distinct and more efficient converter of solar energy, thus having potential to produce huge amounts of biomass. Plant development and growth are basic processes that define crop yield. Development and growth of crop can be estimated based on their morphophysiological parameter study. The relative effects of yield components as stalk number, stalk length, stalk thickness, stalk density on cane yield studied through path coefficient analysis by Khairwal and Babu (1975) revealed that the stalk number was the most important one deciding the yield. Besides inherent varietal efficacy, the stalk popu...

A field experiment was conducted during the spring season of 2012-13 at Pusa (Bihar), to study the effect of plating geometry and varieties on physio-agronomic characteristics of sugarcane (Saccharum spp. hybrid complex). The rate of increase of dry matter, AGR and RGR was very rapid rate in between 150-180 DAP, which gradually decreased with advancement of crop age. The maximum dry matter of individual plant was accumulated at 150 cm row spacing followed in order by 120 cm row spacing. The effect of planting geometry with respect to brix, pol and purity percentage were found to be non significant. However, comparatively higher values was observed under 90 cm row spacing at 270 and 300 DAP. The maximum sugar yield (11.18 t/ha) was observed at 90 cm row spacing which was 2.6, 27.3 and 54.4% higher than 30: 120, 120 and 150 cm row spacing, respectively. Among varieties, the significantly highest dry matter accumulation was recorded with 'BO 139' followed in order by 'CoP 9301' at all the stages of growth. Varietal differences in respect to brix, pol, purity, juice recovery and CCS percent and TC: TS ratio was found to be significant and a higher value was obtained due to the variety 'CoP 9301'. Though significantly higher sugar yield (10.68 t/ ha) was registered by BO 153.
Correlation and Path Analysis for Yield and Quality Attributes in Sugarcane
An investigation was conducted at the Zonal Agricultural Research Station V.C. Farm, Mandya, Karnataka, India during 2008-2009 under irrigated condition for studying correlation and path coefficient analysis in thirty selected clones of sugarcane (Saccharum spp) plant crop for yield, yield components and quality characters. Analysis of variance revealed significant difference for all the characters studied. The cane yield considered as the most important character of sugarcane was positively and significantly correlated with sugar yield, single stalk weight, number of tillers, stalk length, stalk internode length, germination percentage, number of internodes. There was also positive significant correlation of number of millable cane and stalk diameter with cane yield. Cane yield was negatively and significantly correlated with juice brix per cent and juice pol per cent, whereas, sugar yield showed positive and significant correlation with single stalk weight, cane length, stalk internode length, CCS per cent, juice pol per cent and juice purity per cent. Path coefficient analysis revealed that sugar yield and number of millable canes were major direct contributors for cane yield. Stalk diameter, germination percentage and stalk length also showed positive direct effect on cane yield. CCS per cent, juice brix per cent, single stalk weight, stalk internode length, number of tillers, juice pol per cent whereas number of internodes had negative direct effect on cane yield. The present study suggests that selection on based sugar yield, number of millable cane, stalk diameter and stalk length would be worthwhile for ameliorating over all juice pol per cent and cane yield.
