“…Further, Million et al also reported a significant linear relationship between stalk height and stalk weight in sugarcane crop, and our study also indicated similar results. Recently, Vasantha et al [3] reported stalk volume (calculation method) in sugarcane with a significantly better correlation with cane yield or stalk weight thus confirming our findings.…”

“…The 32 single canes from various sugarcane clones were earmarked, and the stalk volume was determined based on the calculation method, and after that the stalk was collected, detrashed and the stalk volume was determined by the water displacement method. The plant height was measured from the base to the top most visible transverse mark on the 300 th day after planting (DAP) using a measuring tape and the shoot thickness with a digital vernier caliper (Mitutoyo) [3]. Also, the single cane weight of 73 sugarcane clones (10 months old) was used to find the association of SCW with the stalk volume derived through the calculation method.…”

“…The ICAR-SBI has developed more than 2800 Co canes and they are of massive importance for their high variability and suitability against biotic and abiotic stress. In order to screen these sugarcane clones for higher productivity high throughput tools are highly essential, and estimation of stalk volume by calculation method has been reported as one of the traits for predicting stalk weight/yield in a non-destructive way [3].…”

“…Among the various crop, the canopy coverage is being discussed for measuring canopy volume and its association with crop yield, while in sugarcane, the stalk portion is the primary/economic product of the crop, and identification of stalk fresh weight is essential to predict the crop yield. Mostly the sugarcane stalk is considered cylindrical in shape and the formula for calculating the cylinder volume [8,9] is used for determining the stalk volume of sugarcane [3] which has a high correlation with crop yield, and very few reports are available in this type of findings. Vasantha et al [3] have reported the association of stalk volume by calculation method with the stalk weight.…”

A comparison of the water displacement method and stalk volume calculation method for stalk weight determination in sugarcane clones has not yet been established till data and very few reports are available for the non-destructive calculation of the fresh weight of sugarcane stalk, and the present investigation was carried out with the objective (i) to compare the water displacement method and stalk volume calculation method for the stalk volume determination and (ii) to find the association between the stalk volume with stalk weight for the estimation of the single cane weight of sugarcane crop rapidly in nondestructive way.…”

The present study was conducted to identify the association of non-destructive rapid estimation of stalk volume by calculation method with water displacement method and to predict the single cane weight by stalk volume. The stalk volume by water displacement method (SVWM) and stalk volume by calculation method (SVCM) were compared for the efficacy of stalk weight determination in sugarcane clones. Results from both methods were similar and a highly significant relationship was found between the two methods (r2 = 0.9092, P < 0.0001). Both protocols provide consistent stalk volume measurements; however, the stalk volume calculation method is preferred for its quick evaluation of a large number of stalks in a rapid way besides its non-destructive nature. The calculation method saved more than 70 seconds for each sample. The stalk weight has shown a significant correlation of r=0.71***, 0.83***, 0.94***, 0.99*** with SH, CD, SVCM and SVWM respectively, while the stalk density (SD) was observed with a negative correlation (r=-0.27ns) with stalk weight. The stalk volume-based predicted stalk weight estimation was observed with high degree of correlation (>0.88***) with the original single cane weight by both the studied methods, thus, measurements of stalk volume based on calculation method which provide simple, rapid, non-destructive field phenotyping of single cane weight in sugarcane crop may be recommended for the sugarcane research.

Screening for elite sugarcane genotypes for canopy cover in a rapid and non-destructive way is important to accelerate varietal/clonal selection, and little information is available regarding canopy cover and leaf production, leaf area, biomass production, and cane yield in sugarcane crop. In the present investigation, the digital images of sugarcane crop by using Canopeo software was assessed for their correlation with the physiological and morphological parameters and cane yield production. The results revealed that among the studied parameters, canopy coverage has shown a significantly better correlation with the plant height (0.581 **), leaf length (0.853 **), leaf width (0.587 **), and leaf area (0.770 **) in commercial sugarcane clones. Two-way cluster analysis has led to the identification of Co 0238, Co 86249, Co 10026, Co 99004, Co 94008, and Co 95020 with better physiological traits for higher sugarcane yield under changing climate. Additionally, in another field experiment with pre-breeding, germplasm, and interspecific hybrid sugarcane clones, the canopy coverage showed a significantly better correlation with germination, shoot count, leaf weight, leaf area index, and plant height, and finally with biomass (r = 0.612 **) and cane yield (r = 0.458 **). It has been found that the plant height, total dry matter (TDM), and leaf area index (LAI) had significant correlation with the cane yield, and the canopy cover data from digital images act as a surrogate for these traits, and further it has been observed that CC had better correlation with cane yield compared to the other physiological traits viz., SPAD, total chlorophyll (TC), and canopy temperature (CT) under ambient conditions. Light interception determined using a line quantum sensor had a significant positive correlation (r = 0.764 **) with canopy coverage, signifying the importance of determining the latter in a non-destructive way in a rapid manner and low cost.
