Context: The prime concern of cane growers and the sugar industry is to achieve higher sugarcane productivity and high sugar recovery both of which support maximum economic return. This requires newly developed sugarcane genotypes.Objectives: To study the performance of newly developed sugarcane genotypes for plant crop and ratooning ability in U.P. Condition.   Materials and Methods: The performance of newly developed sixteen promising sugarcane genotypes along with three standards check viz.; CoJ64, CoS95255 and CoS767 were evaluated during 2005-07 at Shahjahanpur, Uttar Pradesh, India. Results: The experimental results revealed that significantly higher commercial cane sugar (CCS) yield was observed by the genotype UP49 (13.19 t ha-1), CoS06262 (13.67 t ha-1), CoS05263 (13.70 t ha-1), CoS06247 (12.67 t ha-1), CoS05259 (13.12 t ha-1) over three standards CoS767 (9.41 t ha-1), CoJ64 (9.54 t ha-1) and CoS95255 (12.56 t ha-1). The genotype UP49 (10.50 t ha-1) recorded highest CCS% followed by CoS06247 and CoS05263 having 10.49 t ha-1 and 10.29 t ha-1 respectively in ratoon crop. Amongst all the genotypes UP49, CoS06262, CoS05263, CoS06248, CoS06253, CoS05259 and CoS06263 were proved significantly superior over all the three standards checks in respect of cane yield. Conclusion: The UP49 was found the best performer and superior to widely adopted variety CoS767 in respect of cane yield, commercial cane sugar percent, sugar yield and pol percent in cane; under plant and ratoon crops. Key words: Sugarcane; ratoon; CCS%; sugar yield and productivity.DOI: 10.3329/jbs.v17i0.7099J. bio-sci. 17: 41-44, 2009

A field experiment was conducted to assess performance of newly developed six mid early maturing sugarcane cultivars i.e. Co 0116, Co 0118, Co 0237, Co 0238, Co 0239 and Co J 64 (Standard), with two row spacing (75 and 90 cm) under three fertility levels i.e. 75, 100 and 125% of recommended dose of fertilizers (RDF) NPK (N150 P21.8 K41.5) with plant-ratoon-wheat system. Varieties ‘Co 0238’ and ‘Co 0118’ recorded the maximum and significantly higher cane yield (93.1 and 88.9 t/ha) and commercial cane sugar (11.76 and 12.49 t/ha) and outperformed rest cultivars in plant and ratoon crop, respectively. However, both cultivars did not differ significantly for cane yield and commercial cane sugar (CCS). Growth attributes like cane length and cane girth of plant crop were not affected at closer spacing of 75 cm, but number of millable canes (NMC), cane yield and sugar yield increased by 23.94, 20.29 and 19.63% than 90 cm row spacing. While in the subsequent ratoon crop number of millable canes (NMC), cane yield and CCS yield increased substantially by 19.25, 16.70 and 16.92 per cent respectively at 75 cm than 90 cm row spacing. Closer spacing (75 cm) fetched maximum net return (209280 and 118823) with benefit: cost ratio of 1.42 and 2.27 with plant as well as ratoon crop respectively. Except varieties, the quality parameters did not undergo significant variation due to change in row spacing and fertility treatments. In monetary terms also, 100 % RDF found almost equally remunerative with 125 % RDF. Cultivar × fertility level interactions indicated that varieties ‘Co 0238’ and ‘Co 0239’ were equally productive at normal fertility level of 100% RDF. In monetary terms, sowing of Co 0238 of sugarcane variety fetched maximum net returns (285633) followed by Co 0239 ( 253406) and Co 0118( 247453) in two years cropping system of Sugarcane-Ratoon-Wheat system under the sub tropical conditions.

<p>A field experiment was carried out during the spring seasons of 2008-09 and 2009-10 at Varanasi, Uttar Pradesh to find out exact time of earthing up with level of earthing up and optimum doses of nitrogen for getting higher productivity, monetary returns, and changes in the fertility status of soils after harvest of ratoon sugarcane (<em>Saccharum officinarum</em> L.). Twentieth fifth April earthed crop produced significantly more height of tillers, leaf area index at maximum tillering stage, grand growth stage and at harvest, dry matter/tiller at maximum tillering stage at grand growth stage and at harvest, cane length, cane diameter of top, middle and bottom, weight of cane, cane yield, monetary returns, B/C ratio, N, P and K uptake except number of tillers/ha, number of millable cane/ha and net available soil nutrient after the harvest of ratoon crops as compared to 25<sup>th</sup> May and 25<sup>th</sup> June respectively. Twentieth cm height of earthing up from the ridge also significantly increased all the above parameters such as height of tillers, LAI of maximum tillering stage, grand growth stage and harvest, dry matter/tiller at maximum tillering stage, grand growth stage and at harvest, cane length, weight of cane and cane yield than that of 10 cm earthed crop in both the ratoon crops. Application of 210 kg N/ha linearly and significantly increased number of tillers/ha at 60 and 120 days after ratooning, height of tillers at 120 days after ratooning, LAI at maximum tillering stage, grand growth stage, and at harvest, dry matter/tiller at maximum tillering stage, grand growth stage and at harvest, number of millable cane, cane length, cane weight, cane yield, monetary returns, B/C ratio and N, P, K uptake followed by 180 kg N/ha. Ratoon crop showed that there was a build up of nitrogen and phosphorous but depletion in potassium content of the soil. 210 kg N/ha with earlier earthed at 25<sup>th</sup> April to a level of 20 cm was found optimum for obtaining higher yields and monetary returns.</p>

Eleven early maturing sugarcane clones were planted in Randomized Block Design for this study. The objective of this study was to investigate the relationships among the yield and quality parameters with cane yield and sugar yield in sugarcane, in order to provide information to help breeders in adopting traits for developing high yield and quality varieties. The analysis of variance revealed significant differences among genotypes for eleven yield and quality characters. Highest cane yield (176.66 t/ha) was recorded in clone 2015R10 and highest Commercial Cane Sugar (CCS) % (14.16) were observed in Co C 671. Correlation coefficient results indicated that cane yield was positively correlated with germination (0.166), number of millable canes (0.210), cane length (0.650), cane girth (0.610), single cane weight (0.880), CCS yield (0.518) whereas Brix% (-0.838), Sucrose% (-0.821), Purity % (-0.720) and CCS % (-0.812) showed negative correlation with cane yield. Sugar yield per hectare is positively correlated with purity% (0.187), cane length (0.413), cane girth (0.503), single cane weight (0.515) and cane yield (0.518). Results indicate that the genotypes should be selected on the basis of cane length, cane girth and single cane weight for getting higher sugarcane yield.

Low levels of commercial cane sugar (CCS) reduce relative economic value (REV) in sugarcane. In the Australian sugarcane industry, CCS is lower early (June) compared with the completion (November) of the harvest period. Performance of sugarcane genotypes in 2 Central region series and 1 Burdekin region series of final stage selection trials was examined to determine if independent selection programs are required to select elite genotypes for 2 target periods: (a) early (before July), and (b) mature (from July on). Across series, CCS (16.83 v. 12.02% fresh cane weight) and REV (AU$3937/ha v. $3123/ha) were significantly higher in the mature than in the early period, while genotypic variance for CCS (0.76 v. 0.33), and broad-sense heritability for CCS (0.96 v. 0.86) and REV (0.79 v. 0.69), were higher in the early than in the mature period. Genetic correlations between sample times less than 3 months apart were usually ≥0.9 for CCS, but generally declined to ≤0.6 for times greater than 3 months apart. Consequently, genotype × period (early compared with mature) interaction effects on CCS affected selection decisions, especially in the Central region, and genetic improvements for CCS would be expected via specific targeting of early and mature periods. However, genotype × period interaction effects were not important for cane yield or REV, such that selection for specific adaptation to early or mature periods would not improve gains in REV across the entire harvest period. Some final stage selection trials should be harvested early in the harvest period, when heritability and genotypic variance are highest, to capture high early CCS genotypes with acceptable cane yield for recycling in breeding activities. This protocol should enhance genetic gain for early CCS and simultaneously increase REV early in the harvesting period of the Australian sugar industry.

<p>Sugarcane is proved to absorb more Si than any other nutrient from soil; therefore continuous cropping of the plant at the same soil would bring consequences of more Si and organic matter depletion. Silicon (Si) is considered a beneficial nutrient for sugarcane production. Field study was carried out in 2013-2014 at Kempleng village; Purwoasri sub district; Kediri district; East Java. The objective was to find out the effect of frequency and concentration of Si liquid fertilizer on Si and N absorptions, stem diameter and length, yield and commercial cane sugar (CCS) of sugarcane var PSBM 901. Split plot design with three replicates was employed to arrange the treatments. As main plots were frequency of spraying (one time, two times, three times, and four times with interval of 20 days started at 30 days after planting), while as sub plots were concentration of Si fertilizer (0, 15% Si, 30% Si). Results showed that interaction between frequency and concentration of Si affected on all parameters observed. Spraying of sugarcane four times with 30% Si gave highest value of cane yield, rendement, and sugar yield, i.e. 184.16 tons/ha and 8.36%, 15.37 ton/ha respectively.</p>

A field experiment was conducted during 2018-20 to evaluate the effect of different organic amendments on yield and quality of sugarcane ratoon in calcareous soil at Crop Research Centre, farm at Dr. Rajendra Prasad Central Agricultural University, Pusa, Bihar. The experiment was conducted in randomized block design with 8 treatments viz. control, FYM (farmyard manure) @ 20 t ha-1, biocompost (BC) @ 20 t ha-1, vermicompost (VC) @ 5.0 t ha-1, green manure with moong, sugarcane trash @ 10 t ha-1, FYM + BC+ VC (1: 1: 0.5) @ 20 t ha-1 and recommended dose of fertilizer (RDF) as NPK (170: 50: 60 kg ha-1) and replicated thrice in sugarcane plant-ratoon system. The sugarcane plant crop was taken and after harvest of plant, the ratoon crop was initiated. Addition of organic amendments significantly increased the number of tillers, millable cane and ratoon cane yield which was at par with recommended dose of fertilizer. The cane juice quality was not affected due to different treatments. The mean cane yield (61.7 - 77.1 t ha-1) and sugar yield (4.06-10.56 t ha-1) varied significantly in organic added plots t ha-1 which was found at par with RDF. The sugar yield followed the similar trends of cane yield. The SMBC (soil microbial biomass carbon), CO2 evolution and carbon stocks were significantly higher in organic amendment added plots indicating improvement in soil carbon status. The highest value of CO2 evolution, SMBC and carbon stocks were observed in the treatment receiving FYM+BC+VC in combination (1: 1: 0.5). Organic amendments had beneficial impact on restoration of soil carbon status, cane and sugar yield of ratoon crop of sugarcane in calcareous soil.

Field studies were conducted in Louisiana to determine growth and yield effects resulting from the accidental application of the isopropylamine formulation of glyphosate to sugarcane. Glyphosate at 0.1, 0.2, 0.4, and 0.8 kg ae ha–1was applied in water at 90 L ha–1in May, June, and August. Sugar yields (kg ha–1) were reduced 44% when glyphosate was applied over the top of sugarcane at 0.2 kg ha–1in June; similar reductions for the May and August applications required 0.4 kg ha–1. Reductions in sugar yield were primarily attributed to reductions in both cane yield and recoverable sugar in the crushed juice because stalk populations and stalk weights were lowered and immature stalks that survived contained less sugar. The recoverability of the subsequent ratoon crop was also affected, particularly when glyphosate was applied in May and June to the previous crop at rates of 0.4 kg ha–1and higher.

Previous experiments in the Australian tropics have observed a 'slowdown' in biomass accumulation in mature sugarcane crops. By installing scaffolding to prevent lodging, we eliminated the growth 'slowdown' in 3 experiments to confirm that lodging and stalk death are part of the explanation. In both the wet and dry (irrigated) tropics, lodging of sugarcane significantly decreased both fresh cane yield and commercial cane sugar content (CCS). Prevention of lodging increased cane yield by 11–15%, CCS by 3–12%, and sugar yield by 15–35% at the final harvest in August–September. The rate of increase in CCS in lodged cane was reduced following lodging, although CCS had partially recovered by harvest.A possible component of the lodging effect is a slowdown in the growth due to the ageing of the crop. However, a younger crop (late crop treatment) grew no faster than the scaffolded treatment and so discounted this. In the dry tropics, where cane is irrigated and grows under high radiation, sugar yield was 40 t/ha with scaffolding installed. The increased yield (compared with 35 t/ha in lodged cane) was due to both the survival of an extra 0.8 stalks/m2 and increased accumulation of sugar in live stalks. In 2 years in the wet tropics where sugar yield with scaffolding was 16 t/ha, the same factors, with the addition of increased biomass accumulation in live stalks, were responsible for the increase.

Productivity of sugarcane in Kenya has declined despite use of recommended production practices including introduction of elite high yielding and early maturing sugarcane varieties. Farmers continue to use recommended agronomic inputs for the old low yielding and late maturing varieties on these elite varieties. Nitrogen fertilizer rates in single or split doses for old varieties are still in use yet their appropriateness on new varieties remains untested culminating to decline in sugarcane productivity in Kenya. Currently, cane payment is based on delivered milling cane weight. The industry plans to change payment to a combination of quality and yields. Influence of agronomic inputs and timing of harvesting period on proposed mode of payment is unknown. Harvesting age in western Kenya remains 18-20 months after ratooning (MAR). However, optimal age that combines quality and yields is not documented. Influence of these agronomic practices on quality, yields and optimal harvesting age of ratoon crop of new (D8484) and old (CO421) varieties were evaluated in a 2x4x3 split-split-plot design replicated three times. Four rates of nitrogen as urea, all applied at 3 MAR, split once (50-50%) and applied at 3 and 6 MAR or split three times (40-30-30%) and applied at 3, 6 and 9 MAR were evaluated. Yields and quality parameters were monitored from 10th-24th MAR. Variety D8484 out-yielded (p≤0.05) CO421 throughout demonstrating its superiority. Yields reached maximum at 20 and 19 MAR for CO421 and D8484, respectively. Maximum pol and brix were attained at 18 and 15 MAR for CO421 and D8484, respectively, while commercial cane sugar (CCS) was maximum at 18 and 17 MAR for CO421 and D8484, respectively. Results demonstrated that for high returns, D8484 should be harvested between 15-18 MAR while CO421 between 17-19 MAR. The 60 kg N/ha, that produced higher (p≤0.05) output in both varieties, from 16th MAR is recommended for both varieties. Split fertilizer application did not affect productivity.

The performance of promising varieties was compared with already released. The varieties trail was conducted at four different sites in Punjab, it is an essential component of sugarcane research and thus provides an important basis of recommendations to growers. The objective of this paper is to evaluate promising varieties under different ecological zones. Seven sugarcane promising and two commercial clones were evaluated. These clones were tested for their performance at four locations during Feb-March-2017 in “Thal” and South Punjab viz; Karampur Mailsi, Layyah, Alipur and Khanpur. The trials were conducted at farmer’s field using RCBD with three replications. The data on germination%, Tillers/Plant, number of mill able cane, cane yield t/ha and commercial cane sugar% (CCS) were recorded during the course of study. Overall, pooled mean of four locations indicate that cane yield of clone S2003-US-127 produced statistically higher significant 124.64 t/ha cane yield as compared HSF-240 that produced statistically lower yield i.e. 103.14 t/ha. The Brix% of overall mean of four locations results S2003-US-633 was statistically significant i.e. 24.47% and Brix% of overall mean of four locations results S2008-AUS-134 was statistically lower i.e. 19.38%.
