<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 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.

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 Tully Sugar Mill has collected information about sugarcane supplied for crushing from every block in the mill district from 1970 to 1999. Data from 1988 to 1999 were analysed to understand the extent of the variation in cane yield per hectare and commercial cane sugar in the Tully mill area. The key factors influencing the variation in cane yield and commercial cane sugar in this commercial environment were identified and the variance components computed using a restricted maximum likelihood methodology. Cane yield was predominantly influenced by the year in which it was harvested, the month when the crop was ratooned (month of harvest in the previous year) and the farm of origin. These variables were relatively more important than variety, age of crop or crop class (plant crop, first ratoon through to fourth or older ratoons) and fallowing practice (fallow or ploughout-replant). The month-of-ratooning effect was relatively stable from year-to-year. Commercial cane sugar was influenced by the year of harvest, the month of harvest and their interaction, in that the influence of the month of harvest varied from year to year. Variety and farm differences were also significant but accounted for a much lower portion of the variation in commercial cane sugar. An empirical model was constructed from the key factors that influenced commercial cane sugar and cane yield to quantify their combined influence on sugar yield (t/ha). This may be used to assist mill personnel to predict their activities more accurately, for example to calculate the impact of a late finish to the current harvest season on the following year's crop.

<p class="Default">ABSTRACT</p><p class="Default">Organik matter has an important role in determining soil health of sugarcane, i.e. soil capacity to support sugarcane to produce sustainable high yield. Soil organic matter influences soil physical, chemical, and biological properties, so that a consequence of declining soil organic matter is poorer soil fertility and lower yield. This paper has an objective to elucidate the important role of organic matter on sustainable farming of sugarcane. The important role of organic matter in soil fertility has been known for a long time before Green Revolution concept was introduced. With more intensity in sugarcane farming and more increasing of sugar demand, application of organic fertilizer started to be substituted by chemical fertilizer. Using green manure and/or biofertilizer has a chance to be spread out to the farmers due to more practical and more efficient than solid organik fertilizer, such as dung manure or compost. Future research should be focusing on the efectivity of green manure and or biofertilzer sources in improving soil fertility and cane yield, minimizing soil pathogen, reducing soil erosion of sugar cane land monoculture, and improving awareness of farmers about soil degradation as consequences of sugarcane monoculture planting for years.</p><p class="Default">Keywords: Organic matter, sugarcane, soil health sustainable farming</p><p class="Default"> </p><p class="Default"><strong>Bahan Organik: Peranannya dalam Budidaya Tebu Berkelanjutan</strong></p><p class="Default">ABSTRAK</p><p class="Default">Bahan organik tanah berperan penting dalam menentukan kesehatan tanah tebu, yaitu kapasitas tanah yang dapat mendukung produksi tebu yang tinggi secara berkelanjutan.

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.

Highlights`Significant reductions in canopy temperature depression (CTD), chlorophyll fluorescence (Fv/Fm), SPAD index, and leaf rolling index were observed under limited irrigation during the grand growth stage of sugarcane.This study highlights the significance of CTD and Fv/Fm as useful physiological tools for selecting sugarcane clones suitable for production under water-limited conditions.Clones Co 10026, Co 13006, Co 85019, Co 62175, Co 86010, and Co 1148 performed better under limited irrigation, and these clones can reduce the amount of irrigation water required for sugarcane production, ensuring water security.Abstract. Sugarcane is one the most important commercial crops in India and globally. The annual water requirement for sugarcane ranges from about 1000 to 2900 mm, and this variation mainly depends on the agro-ecological conditions, cultivation practices, and crop cycle. In a changing climate, the delay or failure of monsoons will have a direct effect on the water available for irrigation in India. Given these constraints, sustaining sugarcane production is challenging. The ICAR-Sugarcane Breeding Institute (ICAR-SBI) in Coimbatore, India, has developed sugarcane genotypes that are resilient to drought stress. To study the role of physiological traits in identifying sugarcane varieties suitable for water-limited conditions, an experiment was conducted at ICAR-SBI with sugarcane clones in field conditions using irrigation at 100% cumulative pan evaporation (I0) and with 50% reductions in the volume and frequency of irrigation (I2). Physiological traits, including canopy temperature depression (CTD), chlorophyll fluorescence (Fv/Fm), soil plant analysis development (SPAD) index, leaf rolling index (LRI), and cane yield, were recorded for sugarcane clones grown under I0 and I2. Significant reductions of 85.9%, 15.4%, 4.9%, 44.9%, and 56.0%, respectively, in CTD, Fv/Fm, SPAD index, LRI, and cane yield were found for water-limited conditions (I2) compared to I0. Fv/Fm showed a decreasing trend in I2 compared to I0 and also showed a significant positive correlation (r = 0.43) with cane yield. CTD varied significantly between the two treatments and also showed a significant positive correlation with cane yield (r = 0.45). Both Fv/Fm and CTD are adaptive traits for water-limited conditions and are useful for screening sugarcane clones suitable for water-limited conditions. Clones Co 10026, Co 13006, Co 85019, Co 62175, and Co 86010 had superior cane yields under water-limited conditions (I2) and better physiological traits. Water deficit is one of the most critical abiotic stresses that affect sugarcane productivity. By growing clones that are water use efficient (Co 10026, Co 13006, Co 85019, Co 62175, and Co 86010), the irrigation water requirement can be reduced for sugarcane production in India. In addition, new sugarcane clones can be developed for water-limited conditions by using the identified clones in breeding programs for water use efficiency, and water security can be achieved for sugarcane grown tropical and sub-tropical areas of India.

AbstractDissipation of S-metolachlor, a soil-applied herbicide, on organic and mineral soils used for sugarcane production in Florida was evaluated using field studies in 2013 to 2016. S-metolachlor was applied PRE at 2,270 g ha−1 on organic and mineral soils with 75% and 1.6% organic matter, respectively. The rate of dissipation of S-metolachlor was rapid on mineral soils compared with organic soils. Dissipation of S-metolachlor on organic soils followed a negative linear trend resulting in half-lives (DT50) ranging from 50 to 126 d. S-metolachlor loss on organic soils was more rapid under high soil-moisture conditions than in corresponding low soil-moisture conditions. On mineral soils, dissipation of S-metolachlor followed an exponential decline. The DT50 of S-metolachlor on mineral soils ranged from 12 to 24 d. The short persistence of S-metolachlor on mineral soils was likely attributed to low organic matter content with limited adsorptive capability. The results indicate that organic matter content and soil moisture are important for persistence of S-metolachlor on organic and mineral soils used for sugarcane production in Florida.
