Topographical areas better adapted for sugar cane cultivation must be identified and preserved, for this study Indus valley river delta in South Punjab represents promising features for prosperous sugarcane cultivation (lower water pumping costs due to higher water tables, sugarcane being flood resistant crop in Pakistan. Eight sugarcane varieties and eight promising clones were grown on different locations in Punjab at farmer’s field using RCBD with three replications. The objective of this study is to evaluate varieties under different ecological zones. These clones were tested for their proficiency at four different locations during 2018-19. The “Thal” and Southern Punjab viz; 142/TDA Lalazar Layyah, Indus Sugar mills Rajanpur, Ashraf Sugar Mills Bahawalpur and Adam Sugar Mills Chishtian. The data on germination %, tillers / plants, Number of mill able canes, canes yield tones/ ha and commercial cane sugar (CCS) were recorded during the course of study. It is obvious from pooled mean of four locations that cane yield of clone S2002-US-133 gave 84.13 % higher cane yield as compared the check variety CPF 248 as far as CCS% is concerned, sugarcane clones S200-US-633 and S200-US-133 gave the higher sugar recovery that is 15.31 % & 15.23 % respectively more than check variety. Whereas S200-US-658 and HSF240 have the lowest CCS% 1.22 & 1.14 % less than check.

Sugarcane is the crop that have the quality to sprout after its first harvesting, phenomenon known as ratooning. Among all other major crops, sugarcane ratooning is widely acceptable to farmers of the Punjab. The more the tillers grew, the higher are the chances of a greater number of stalks to be harvested. It is proven that more the number of stalks, the thinner is the diameter, finally results in more stalks and high production. Similarly, higher number of canes produce favorable ratoon. In this experiment, performance of Seven promising sugarcane varieties/clones along with the check variety CPF-246, were tested for their ratoon ability capacity at farmer’s field at Toba Tek Singh during the year 2017-18. It has been found that one of the varieties S2008-FD-19 produced that maximum ratoon yield, U2003-US-633 produced the maximum sugar recovery and S2003-US-133 produced maximum number of mill able canes. The observing of the current analysis also revealed that S2003-US-633 and S2003-US-133 have significant potential for boom sugar recovery through breeding programs and by improving the production techniques.

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%.

The experiment was conducted to evaluate growth and nitrogen uptake of the twelve sugarcane varieties, viz. NiF3, NiF8, Ni9, Ni12, Ni15, Ni17, Ni21, Ni22, Ni25, Ni27, Ni28, and Ni29, under rain-fed conditions during the period from 70 to 160 days after transplanting (DAT) at the experimental field, Faculty of Agriculture, University of the Ryukyus, Okinawa, Japan. The results showed that water shortage from a rain-fed condition caused reductions, but not significant in plant height and SPAD of sugarcane varieties. The genetic variation in leaf area, yield components, partial and total biomass, and cane yield was found among the investigated varieties. The positive associations between total nitrogen uptake with total biomass production and cane yield suggested that higher nitrogen uptake supports better growth performance of sugarcane under rain-fed conditions. From this study, NiF3 and Ni27 could be introduced as the promising sugarcane varieties for better growth performance and high nitrogen uptake under rain-fed conditions.

Sugarcane stalk population is a key determinant of cane yield and knowing the right intra-row spacing is a critical factor in sugarcane production for a given environment. Therefore, a field experiment was conducted at Omo Kuraz Sugar Estate during the 2018/ 2019 cropping season to determine the effect of intra-row spacings (5 cm overlapping, end-to-end, 5 cm spacing between setts and 10 cm spacing between setts) on growth, yield, yield components and quality parameters of sugarcane varieties (N14, Mex54/245 and C86/112). The treatments were arranged in a split-plot design with three replications. Varieties were represented as the main plot whereas setts spacing treatments were assigned to sub-plots. Analysis of variance revealed that the intra-row spacing effect didn’t show a significant difference in the number of tillers, plant population, millable cane, cane yield, sugar yield, and Brix percent whereas significant (P<0.05) differences were observed in stalk height, stalk girth, number of internodes and weight per stalk. Therefore, the 10 cm intra-row spacing of three budded setts can be recommended for better productivity and profitability of N14 and Mex54/245 varieties at the Omo Kuraz Sugar factory.

Commercial cane sugar (CCS), as measured by sugar mills, is in decline in the wet tropics of Australia. One of these mills, Tully Sugar Ltd, has measured CCS in the factory as required by legislation and also measured whole clean stalk CCS through a small mill, which is free of contaminants. ‘Factory CCS’ measures the CCS of cane entering the mill, after it has been harvested. The harvesting and transport process delivers to the mill cane that is contaminated by extraneous matter such as leaf material and soil. Beween 1988 and 1998, 1516 blocks were sampled for ‘small mill CCS’. These data were combined with block productivity information to determine the trends in small mill CCS and factory CCS using a linear mixed model analysis as the data were unbalanced. Other data, including the date of harvest for factory CCS, date of sampling for small mill CCS, farm of origin and cane variety were available and fitted as random effects in the mixed model. Year was fixed to determine time related trends in the 2 measures of CCS. Small mill CCS was higher than factory CCS and remained constant from 1988 to 1998. Predicted factory CCS declined from 12.76 units in 1988 to 10.91 units in 1998. We conclude that the CCS levels in whole clean stalks were actually stable, since small mill CCS remained constant over the 10-year period. Possible reasons for the differences in the trends for the 2 CCS measures are discussed.

Selection in sugarcane from true seed was recently implemented in Ivory Coast with the aim to increase the genetic variability of crop material used and, therefore, improve significantly sugar yields with a positive impact on the competitiveness of the Ivorian sugar industry. The objective of study was to determine the best performing cane genotypes among 29 clones tested under sprinkler irrigation, in comparison with a check variety (R579). It was carried out on R3-002 commercial sugarcane plantation of Ferké 2 sugar estate, in northern Ivory Coast. The experimental design used was a randomized complete block with 30 cane genotypes in three replications. Each plot comprised 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. Based on sugar yields, four promising genotypes namely RCI12/15, RCI12/19, RCI13/121 and RCI13/136 were equivalent to the check variety which performed 15.6 t/ha. They are due to undergo the advanced selection stage during the 2020-21 cropping season for three more years for determining the first new sugarcane varieties of RCI origin to be tested commercially in Ferké sugar estates. Their yield performances ranged from 12.8 to 13.8 t sugar/ha, i.e. from 134.0 to 144.8 t cane/ha compared to 161.3 t/ha for the control variety. Although a relatively high level of stem-borer infestation rate recorded, with 15.6% on average (almost three times the tolerable threshold value of 5%), reasonable values of sucrose percent obtained with the promising genotypes, ranged from 12.7 to 13.9% over both crop cycles, compared with 13.6% for the check. Higher heritability values ranging from 61 to 80.5% were observed in traits like sugar yield, sucrose content (62.6%), recoverable sucrose (60.6%), fiber content (72%), stem-borer infestation rate (80.5%), number of internodes/stalk (67.7%), and flowering rate (79.6%). In contrast, lower and moderate values of heritability were observed for Pol juice (59.8%), juice purity (50.5%), cane yield (53%), millable stalk number/ha (29.5%), single stalk weight (36.7%), single stalk height (45%), and single stalk diameter (38.7%).

Abstract. Paganico is a little village located in the south-eastern portion of the Lucca Plain (North Western Tuscany, Italy). Since Seventies a few square kilometres area around Paganico has been involved in opening of small cavities (sinkhole-like features – in this work named micro-sinkholes for simplification) on the land surface. At the beginning they were very small and sporadic. Then (in Eighties), the phenomenon has been characterized by a significant extension, increasing in frequency and size (up to 2 m in diameter and depth), causing inconvenience to local people, agricultural operation and sometimes damage (cracks to buildings, walls, floorings). The cavities prevalently occur at the end of the dry season, during or immediately after the first intense rainy events, that is between the end of summer and autumn. Even so the predisposition and triggering causes are not at present completely clarified. Therefore this study is aimed at individuating the triggering and evolution mechanism of the Paganico micro-sinkholes, particularly referring to the stratigraphic, hydrogeological and geotechnical features of the involved materials. Another important issue made clear with this research is represented by the overexploitation involving the local aquifer, characterized by particular hydro-structural conditions. In fact, the Paganico underground shows three horizons with different lithologic, hydrogeological and geotechnical properties: a superficial silty-sandy horizon (2–3 m thick), which is particularly involved in collapses; an intermediate silty-clayey horizon (2–4 m thick); a lower and thick gravel-pebbly horizon, interested by important water resources and heavy pumping. Since Seventies, such water pumping considerably rose, due to the local demographic (well-field), industrial (paper manufacture) and agricultural development. From an hydrogeological point of view, this area is consequently characterized by two water tables: a temporary one, housed in the superficial silty-sandy horizon (aquitard), and a second one, confined, associated to the lower gravel-pebbly horizon (aquifer). Such water tables are separated by an impermeable silty-clayey horizon. According to the observations resulting from this study, the latter probably tends to fracture by desiccation during the dry season, originating water exchange between the two water tables during the first important autumnal rainfall, depending on the pumping conditions, which lower the piezometric surface of the confined aquifer. Cracking would interest also the superficial horizon. Thus, the water exchange would produce erosional phenomena in the superficial material, with removal of the fine fraction and collapse. This process could be at the base of the micro-sinkholes opening.

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.
