Sugarcane Ratoon

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.

Aims: The study aimed to determine the best performing cane genotypes among 29 clones tested under sprinkler irrigation, in comparison with a check variety (R579). Study Design: The experimental design used was a randomized complete block (RCB) with 30 cane genotypes in three replications. Every plot consisted of two dual rows of five meters with 0.5 and 1.90 m of inter-row spacing, i.e. 19 m² per plot and about 600 m² for the whole experiment. Place and Duration of Study: It was carried out on a commercial sugarcane plantation of Ferké 2 located in the northern part of the country, over 10 months as a late season crop from late May 2018 to late March 2019. Methodology: Over each micro-plot, data were collected at harvest from both dual rows consisted of millable stalk number/ha, cane yield, juice quality traits (sucrose, purity, and recoverable sucrose), fiber content, and damaged internodes by stem borer Eldana saccharina. Results: Based on sugar yields, seven cane genotypes were equivalent to the check variety R579 which gave 17.6 t/ha. Their yield performances ranged from 12.2 to 15.4 t of sugar/ha and from 134.2 to 160.8 t of cane/ha compared to 176.0 t/ha for the check. Higher heritability values ranging from 52 to 85% were observed in traits like sugar yield, juice purity, juice sucrose, recoverable sucrose, sucrose percent, fiber content and stem borer infestations. Differences between PCV and GCV for most traits were small, indicating high prospects for genetic progress through selection under conditions of this study. Conclusions: Findings obtained need to be confirmed over the 2019-20 cropping season in first ratoon crop to determine promising cane genotypes for the advanced selection stage.

Ratooning is common practice done in sugarcane with purpose of reducing total cost of cultivation and early cane maturity. More than 35% of sugarcane productivity is lost due to improper attention of the farmers towards ratoons. Majority of farmers reported that the ratoonability wasn’t  good when harvested in December-January. This experiment was carried out to find the appropriate ratoon shaving time with response to different varieties in sugarcane ratoon crop in the year 2018/19 at National sugarcane research project, Jitpur, Bara. The experiment was conducted in split plot design with four levels of cane genotypes as Co – 0238, CoLk – 94184, Co – 0233 and CoS – 07250 as main plot factor while four harvesting dates as sub plot factor with three replications. Observations of number of millable canes, single cane weight, plant height and single cane diameter were recorded, tabulated and analyzed in R-studio. Ratoon stubble shaving in the month of November had highest number of millable canes (88079/ha) which wasn’t significantly different from the stubble shaving in the month of December, January. Likewise, highest cane yield(60.04 mt/ha), single cane weight (0.757kg), cane diameter ( 2.11cm),  plant height(1.82m)were found in early stubble shaving dates . Cane Yield and various yield parameter shows better performance in early ratoon shaving periods i.e. from November to January than late ratoon shaving dates.

Remote sensing techniques and the use of Unmanned Aerial Systems (UAS) have simplified the estimation of yield and plant health in many crops. Family selection in sugarcane breeding programs relies on weighed plots at harvest, which is a labor-intensive process. In this study, we utilized UAS-based remote sensing imagery of plant-cane and first ratoon crops to estimate family yields for a second ratoon crop. Multiple families from the commercial breeding program were planted in a randomized complete block design by family. Standard red, green, and blue imagery was acquired with a commercially available UAS equipped with a Red–Green–Blue (RGB) camera. Color indices using the CIELab color space model were estimated from the imagery for each plot. The cane was mechanically harvested with a sugarcane combine harvester and plot weights were obtained (kg) with a field wagon equipped with load cells. Stepwise regression, correlations, and variance inflation factors were used to identify the best multiple linear regression model to estimate the second ratoon cane yield (kg). A multiple regression model, which included family, and five different color indices produced a significant R2 of 0.88. This indicates that it is possible to make family selection predictions of cane weight without collecting plot weights. The adoption of this technology has the potential to decrease labor requirements and increase breeding efficiency.
