Exploring the efficiency of sugarcane bagasse (Saccharum officinarum) for decontamination of wastewater containing Congo red dye

In present investigation, the adsorptive treatment of synthetically contaminated aqueous solution containing Congo red (CR) by using sugarcane bagasse (SCB) as a low-cost adsorbent was studied. Surface morphological and physio chemical nature of SCB was analyzed by using scanning electron microscopy (SEM), Fourier transform infrared (FTIR) spectroscopy. Adsorption studies were conducted in batch mode to investigate the effect of solution pH, adsorbent dosage, initial dye concentration, contact time, and temperature. Experimental data was evaluated by using Langmuir, Freundlich, and Temkin isotherm model and it was best followed by Freundlich isotherm. Different kinetic models were also studied, and pseudo second order was concluded to be the best followed with R 2 = 1 and Q e ( cal ) = 0.935 mg g − 1 which was very close to the experimental Q e ( exp ) = 9.976 mg / g . R L value in current investigation is 1 which indicates that adsorption of SCB onto CR dye is favorable. The negative values of thermodynamic parameters ( Δ G and Δ H ) revealed that adsorption of CR onto SCB was spontaneous and exothermic in nature, respectively. The adsorbent (SCB) also reflects excellent recyclability, 76% of the adsorbent was regenerated and available for further adsorption experiments. Applicability of developed procedure with tap water was also checked out and results revealed that 70% of CR dye had been adsorbed under optimum condition. It suggests that SCB possess a potential to be used as an effective, and low-cost adsorbent for adsorption of CR dye from industrial effluents.

Stability analysis for cane and sugar yield of advanced sugarcane (Saccharum officinarum) genotypes

The present investigation was undertaken to ascertain stable genotypes across nine environments. Ten advanced genotypes including three checks of themid-late group were evaluated for their adaptability in respect of cane yield, CCS yield and sucrose (%) for two crop seasons 2009-10 and 2010-11 under three locations with three cuttings. The stability of genotypes was worked out by using the model of Eberhart and Russell (1966). The regression coefficient (bi) and deviation from regression (S2 di) were used to define genotypic stability. Mean square due to G x E for all the characters was not significant. The genotypes CoBln 05502, CoP 05437 and CoP 9301 were stable and suitable for cane and CCS yield under favorable environments, while BO 91 was stable for CCS yield and sucrose per cent in juice under unfavorable environmental conditions. Apart from this, genotype CoP 05437 was on top and most stable and widely adaptable in cane and CCS yield across nine environments.

Acute Toxicity and Effect of an Aqueous Extract of Saccahrum officinarum (Poaceae) on Diuresis in Rat

Saccharum officinarum L (Poaceae) is a plant used as a diuretic and in the traditional treatment of arterial hypertension. This study aims to evaluate the acute toxicity and the diuretic potential of the aqueous extract of Saccharum officinarum (Esol) leaves on the diuresis of rats subjected to water overload. The toxicity results show that Esol is non-toxic at a dose of 2000 mg/Kg B.W. and that the LD50 is greater than this dose. The aqueous extract of Saccharum officinarum has many chemical compounds with diuretic and antihypertensive properties such as polyphenols, flavonoids, sterols and polyterpenes and saponosides. Esol acts effectively on diuresis with 24-hour urine volumes of 12.4 ± 0.74 mL; 11.3 ± 0.72 mL for the doses of 1000 and 1300 mg/kg B.W. whose volumetric urinary excretion (VUE) is greater than 150 %. The Time to First Micturition (TFM) of 41.7 ± 6.2 min and 41.2 ± 3.8 min respectively for these 2 doses. The pH of the urine of rats treated with the extract is more alkaline between 7 and 7.35. These results therefore indicate that the aqueous extract of Saccharum officinarum has a diuretic potential, thus justifying its use in traditional medicine.

Dispersal Mechanisms of Trace Metal Elements in the Environment: The Case of Mineral Wastes Stored in Tshamilemba District of the City of Lubumbashi, DR Congo

Since 2001, the Tshamilemba quarter, located in the City of Lubumbashi (DRC), has been home to copper- and cobalt-producing plants, which generate great amounts of mineral waste, the storage of which has resulted in environmental pollution. Previous studies conducted in the Tshamilemba district have identified the weathering process of stored mineral wastes as the main source of trace metal elements (TMEs) involved in the contamination of soil and well water, and have highlighted the population exposure to cobalt. This study strives to identify or establish the dispersal mechanisms of pollutants in the environment that contaminate soil, surface water and edible plants. This study measured major physicochemical parameters, determined TME concentrations in samples (soil, water and edible plants) and established, based on data from soil sample analysis mathematically processed using Matlab 7.1 software, the spatial distributions of TMEs, in both the upper and deep soil (20 cm). The soil sample analysis revealed an average pH of 7.69 and a value of 9.1 for the near-white crusts collected at some spots. In the soil, TMEs were present in upper layers (Co, Cu, Zn and Fe) and the deep layers (Co, Cu, Pb, Zn and Fe) at phytotoxic concentrations. TMEs were observed in water samples at concentrations (Cu, Co, Mn, Zn and Pb) surpassing the quality standards for drinking water. This also applies to edible plant samples of Saccharum officinarum (Co, Cd, Ni, Mg and Pb) and Musa acuminate (Cd, Co, Pb, Zn, Mn and Ni). TMEs disperse in the environment as airborne particles from aerial erosion and as dissolved species in run-off water, mixed with acidic, metal-rich waters spreading from the weathering of stored mineral waste. TMEs contaminate the surrounding soil near to the surface water and build up in edible plants. Therefore, fear among the population about the environment pollution in Tshamilemba is well justified. Understanding the dispersal mechanisms of TMEs is of paramount importance to better control and to contain mineral pollution and design strategies for minimizing the effects on human health.

Impact of Nonconventional Selection by Insecticides on Susceptibility of the Southern House Mosquito,Culex quinquefasciatus

Mosquitoes are an important target of pest control as they vector pathogens that are associated with many debilitating human diseases. Given that mosquitoes have been selected with insecticides for over 100 years, much is known about the development of insecticide resistance associated with targeted application against populations of these insects. However, off-target selection by applications of insecticides in agricultural and residential sites also impacts development of insecticide resistance and is understudied. Similarly, the impact of selecting one life stage of mosquitoes on the insecticide susceptibility of different life stages is largely unknown. Here, we show that susceptibility to chlorantraniliprole, which is applied in rice (Oryza sativa) and sugarcane (Saccharum officinarum) fields in Louisiana, decreased (5.7- to 12-fold) in populations of Culex quinquefasciatus collected from near these fields compared with a reference field strain. In addition, application of bifenthrin by commercial application on an individual residence increased the resistance frequencies to bifenthrin in 5 nearby residential sites. These increased frequencies of resistance, as measured with diagnostic concentrations of bifenthrin, were highly correlated (R2 = 0.92) between larvae and adults, suggesting that selection of adults also confers resistance to larvae. Finally, esterase activities and bifenthrin susceptibilities were moderately correlated (R2 = 0.4 for larvae and 0.52 for adults), suggesting that multiple mechanisms (including metabolism by esterases) were associated with the observed resistance. Results from this study suggest that nonconventional selection by insecticides is a variable to consider when developing management strategies for populations of Cx. quinquefasciatus.

Potential of Endophytic Fungi as Plant Growth-Promoting Fungi (PGPF) Against Growth of Single Bud Set Seedlings on Sugarcane Plants (Saccharum officinarum L)

Increase of sugarcane productivity must be followed by improvements to a more environmentally sound cultivation system. One of them is the use of endophytes. Endophytic fungi are indeed included in the group of growth-promoting fungi or Plant Growth Promoting Fungi / PGPF and are known to secrete growth hormones such as Indole Acetic Acid (IAA), gibberellin so that they can spur growth. This study aims to determine the type of endophytic fungus that can potentially be PGPF in sugarcane breeding. The research uses sampling methods, exploration, and application of PGPF in sugarcane plants. The results of the identification of endophytic exploration fungi of sugarcane plants obtained five colonies consisting of 4 genera and four species from Trichoderma sp., Aspergillus sp., Penicillium sp., and Fusarium sp. From the results of the potency test, the results were obtained that the soaking of bud set seeds with isolates of the fungus Trichoderma sp., Penicillium sp. Noticeable effect on plant height, stem diameter, and the number of leaves.

Nutritive Profile, Digestibility, and Carbohydrate Fractionation of Three Sugarcane Genotypes Treated with Calcium Oxide

The objective of this study was to evaluate the use of calcium oxide (CaO) on the nutritive profile, digestibility, and carbohydrate fractionation of three sugarcane (Saccharum officinarum hybrids) genotypes: IAC-862480, SP-791011, and CTC-3. Four CaO levels (0, 1.5, 3.0, and 4.5% on a fresh matter basis) were used in a 3 × 4 factorial scheme, whose factors were the three sugarcane genotypes and the four levels of calcium oxide. The chemical composition, carbohydrate fractionation, total digestible nutrients, and in vitro dry matter digestibility (IVDMD) were evaluated. The chemical composition of the treated sugarcane was affected by the genotype and the use of CaO. The CTC-3 genotype showed lower values of crude protein (CP), ether extract (EE), neutral detergent fiber (NDFap), acid detergent fiber (ADF), and phosphorus (p < 0.01) contents when compared to the IAC-862480 genotype. A decreasing linear effect (p < 0.01) of CP, EE, ADF, lignin, cellulose, non-fibrous carbohydrates, and total digestible nutrients was observed with increasing levels of CaO. A quadratic effect was observed for the contents of DM, organic matter, NDFap, and hemicellulose when the sugarcane was treated with CaO (p < 0.05). The treatment of sugarcane with CaO resulted in the reduction (p < 0.05) in the indigestible fraction of sugarcane. The IAC-862480 and SP-791011 genotypes showed a better nutritional profile compared to the CTC-3 genotype. On the other hand, CaO treatment improved IVDMD and decreased the non-digestible fraction of sugarcane.

Genome-wide analysis of NBS-LRR genes revealed contribution of disease resistance from Saccharum spontaneum to modern sugarcane cultivar.

During plant evolution, nucleotide-binding sites (NBS) and leucine-rich repeat (LRR) genes have made significant contributions to plant disease resistance. With many high-quality plant genomes sequenced, identification and comprehensive analyses of NBS-LRR genes at whole genome level are of great importance to understand and utilize them. In this study, we identified the NBS-LRR genes of 23 representative species at whole genome level, and researches on NBS-LRR genes of four monocotyledonous grass species, Saccharum spontaneum, Saccharum officinarum, Sorghum bicolor and Miscanthus sinensis, were focused. We found that whole genome duplication, gene expansion, and allele loss could be factors affecting the number of NBS-LRR genes in the species, and whole genome duplication is likely to be the main cause of the number of NBS-LRR genes in sugarcane. Meanwhile, we also found a progressive trend of positive selection on NBS-LRR genes. These studies further elucidated the evolutionary pattern of NBS-LRR genes in plants. Transcriptome data from multiple sugarcane diseases revealed that more differentially expressed NBS-LRR genes were derived from S. spontaneum than from S. officinarum in modern sugarcane cultivars, and the proportion was significantly higher than the expected. This finding reveals that S. spontaneum has a greater contribution to disease resistance for modern sugarcane cultivars. In addition, we observed allelespecific expression of seven NBS-LRR genes under leaf scald, and 125 NBS-LRR genes responding to multiple diseases were identified. Finally, we built a plant NBS-LRR gene database to facilitate subsequent analysis and use of NBSLRR genes obtained here. In conclusion, this study complemented and completed the research of plant NBS-LRR genes, and discussed how NBS-LRR genes responding to sugarcane diseases, which provided a guide and genetic resources for further research and utilization of NBS-LRR genes.

Plant Waste in the Production of New Materials in Brazil: A Scientometric Analysis from 19912021

Several plant residues can be generated during the stages of industrial processing, such as fruit peel, seeds and bagasse, and these can give rise to high-value products. The management and use of this waste is of global interest. The aim of this study was to evaluate the spatio-temporal evolution of scientific knowledge on the reuse of agroindustrial waste generated in Brazil through a scientometric analysis. To this end, a search was performed in the databases Scopus, Scielo, and Web of Science between the years 1991and 2021. The words used as indexers were agribusiness waste, vegetable waste, fruit waste, biomass waste, plant residue, and chemical characterization. The following selection criteria were adopted: search of indexers by title, scientific articles, articles in English and Portuguese, and articles on plant waste generated in Brazil. There was an increase in publications over the years, with a greater number of studies (21.46%) in the chemistry area, addressing mainly the physical-chemical characterization of materials. In Brazil, sugarcane (Saccharum officinarum L.) was the most studied species with a view to reusing its residues. We identified species from highly threatened Brazilian biomes, such as the Atlantic Forest and Cerrado, with the potential for transformation into new materials. The gaps in knowledge, evidenced in this analysis, suggest that more studies should be carried out on residues of native plant species which impact local communities. In particular, studies could focus on applicability in health and cosmetics, which are promising areas for plant materials and still little investigated.

Global Responses of Autopolyploid Sugarcane Badila (Saccharum officinarum L.) to Drought Stress Based on Comparative Transcriptome and Metabolome Profiling.

Sugarcane (Saccharum spp. hybrid) is frequently affected by seasonal drought, which causes substantial declines in quality and yield. To understand the drought resistance mechanisms of S. officinarum, the main species of modern sugarcane, at a molecular level, we carried out a comparative analysis of transcriptome and metabolome profiling of the sugarcane variety Badila under drought stress (DS). Compared with control group (CG) plants, plants exposed to DS had 13,744 (6663 up-regulated and 7081 down-regulated) differentially expressed genes (DEGs). GO and KEGG analysis showed that the DEGs were enriched in photosynthesis-related pathways and most DEGs had down-regulated expression. Moreover, the chlorophyll content, photosynthesis (Photo), stomatal conductance (Cond), intercellular carbon dioxide concentration (Ci) and transpiration rate (Trmmol) were sharply decreased under DS. These results indicate that DS has a significant negative influence on photosynthesis in sugarcane. Metabolome analysis identified 166 (37 down-regulated and 129 up-regulated) significantly regulated metabolites (SRMs). Over 50% of SRMs were alkaloids, amino acids and their derivatives, and lipids. The five most significantly enriched KEGG pathways among SRMs were Aminoacyl-tRNA biosynthesis, 2-Oxocarboxylic acid metabolism, Biosynthesis of amino acids, Phenylalanine metabolism, and Arginine and proline metabolism (p < 0.05). Comparing CG with DS for transcriptome and metabolome profiling (T_CG/DS and M_CG/DS, respectively), we found three of the same KEGG-enriched pathways, namely Biosynthesis of amino acids, Phenylalanine metabolism and Arginine and proline metabolism. The potential importance of Phenylalanine metabolism and Arginine and proline metabolism was further analyzed for response to DS in sugarcane. Seven SRMs (five up-regulated and two down-regulated) and 60 DEGs (17 up-regulated and 43 down-regulated) were enriched in Phenylalanine metabolism under DS, of which novel.31261, Sspon.04G0008060-1A, Sspon.04G0008060-2B and Sspon.04G0008060-3C were significantly correlated with 7 SRMs. In Arginine and proline metabolism, eight SRMs (seven up-regulated and one down-regulated) and 63 DEGs (32 up-regulated and 31 down-regulated) were enriched, of which Sspon.01G0026110-1A (OAT) and Sspon.03G0002750-3D (P5CS) were strongly associated with proline (r > 0.99). These findings present the dynamic changes and possible molecular mechanisms of Phenylalanine metabolism as well as Arginine and proline metabolism under DS and provide a foundation for future research and sugarcane improvement.

Pengaruh Konsentrasi Pemberian Urine Sapi Fermentasi Terhadap Pertumbuhan Stek Tebu (Saccharum officinarum L.) Single Bud

The bud chip nursery technique is a nursery with one bud which is commonly used in sugarcane. The purpose of this study was to determine the effect of the concentration of fermented cow urine on the growth of single bud sugarcane (Saccharum officinarum L.) cuttings. This study used a randomized block design experiment (RAK) with 5 replications and 5 treatment levels, namely: P0 = without giving fermented cow urine concentration; P1 = Concentration of 25% fermented cow urine; P2 = Concentration of 20% fermented cow urine; P3= Concentration of fermented cow urine 75%; and P4 = Concentration of 100% fermented cow urine. Testing data with Polynomial Orthogonal Test. The results of this study indicate that the concentration of fermented cow urine has a significant effect on the growth of sugarcane cuttings. The higher the concentration of fermented cow urine given, the better the growth of sugarcane cuttings on the variable number of leaves, root length, fresh weight of roots, fresh weight of shoots, and dry weight of shoots. However, giving various concentrations of cow urine did not affect the variable percentage of sprouted cuttings.

Transcriptome dynamics provides insights into divergences of the photosynthesis pathway between Saccharum officinarum and Saccharum spontaneum.

Saccharum spontaneum and Saccharum officinarum contributed to the genetic background of modern sugarcane cultivars. Saccharum spontaneum has shown a higher net photosynthetic rate and lower soluble sugar than S. officinarum. Here, we analyzed 198 RNA-sequencing samples to investigate the molecular mechanisms for the divergences of photosynthesis and sugar accumulation between the two Saccharum species. We constructed gene co-expression networks based on differentially expressed genes (DEGs) both for leaf developmental gradients and diurnal rhythm. Our results suggested that the divergence of sugar accumulation may be attributed to the enrichment of major carbohydrate metabolism and the oxidative pentose phosphate pathway. Compared with S. officinarum, S. spontaneum DEGs showed a high enrichment ofphotosynthesis and contained more complex regulation of photosynthesis-related genes. Noticeably, S. spontaneum lacked gene interactions with sulfur assimilation stimulated by photorespiration. In S. spontaneum, core genes related to clock and photorespiration displayed a sensitive regulation by the diurnal rhythm and phase-shift. Small subunit of Rubisco (RBCS) displayed higher expression in the source tissues of S. spontaneum. Additionally, it was more sensitive under a diurnal rhythm, and had more complex gene networks than that in S. officinarum. This indicates that the differential regulation of RBCS Rubisco contributed to photosynthesis capacity divergence in both Saccharum species.

Assessment of Method and Application Schedule of Fertilizer N and K on Growth and Productivity of Summer Planted Sugarcane Crop (Saccharum officinarum L.) under Wide Spacing

Present investigation was carried out at Regional Research Station, Uchani (Karnal) of CCS Haryana Agricultural University, Hisar, India during 2020-21 to assess the effect of method and schedule of fertilizer application on growth, yield attributes and cane yield of summer planted sugarcane (Saccharum officinarum L.) crop under wide spacing (120 cm). The experiment was arranged in split plot design with two methods of fertilizer application (B1-broadcasting and B2- band placement) as main plot treatments and four sub plot treatments which include application of recommended dose of N and K fertilizer (RDF) in different number of splits at different no. of days after planting (DAP) i.e. T1 (five splits), T2 (six splits), T3 (seven splits) and T4 (three splits). Results concluded that majority of growth parameters, yield attributes and cane yield were significantly affected by both main and sub plot treatments at different stages of crop growth period. Treatment B2 registered significantly higher tiller population (110.59 and102.68 000 ha-1 at 60 and 120 DAP respectively), plant height (91.16, 141.18, 400.12 and 412.13 cm at 60, 120, 180 and 240 DAP respectively), no. of millable canes (NMC) (100.79 and 96.58 000 ha-1 in mid-September and at harvesting respectively) cane length (234.64 cm at harvesting) and cane yield (93.16 t ha-1)compared to B1. Among sub plot treatments, T1 outperformed all the other treatments in terms of growth, yield attributes and cane yield. Treatment T1 registered maximum plant height (150.43, 411.0 and 427.45 cm at 120, 180 and 240 DAP respectively), tiller population (104.72 000 ha-1 at 120 DAP), NMC (102.06 and 95.20 000 ha-1 in mid-September and at harvesting respectively) and cane yield (94.83 t ha-1). Germination percentage, cane girth, no. of internodes per cane and length of internodes was not significantly affected either by main or sub plot treatments.

Evidence of Downregulation in Atmospheric Nitrogen-Fixation Associated with Native Hawaiian Sugarcane (Saccharum officinarum L.) Cultivars.

The study of nitrogen fixation in sugarcane has a long history that has demonstrated high potential but with substantial variation in results. This 32-month study sought to assess the response of nitrogen fixation associated with sugarcane (Saccharum officinarum L. cvs. 'Akoki, Honua'ula, and 'Ula) to available soil nitrogen. Plants were grown in large pots of perlite along with a fixing and a non-fixing plant control and administered liquid fertigation with varying amounts of isotopically enriched nitrogen. Assessment of nitrogen fixation utilized nitrogen isotope tracing and acetylene reduction assay in the target and control plants. Isotope enrichment and acetylene reduction assay both indicated that nitrogen fixation peaked under low nitrogen application, and declined with higher application rates, with agreement between the two methods. These results suggest that sugarcane engages in a downregulation of nitrogen fixation under high nitrogen availability, potentially explaining the high variation in published experimental results. This suggests that nitrogen management and fertilization strategy can impact the atmospheric inputs of nitrogen in sugarcane cultivation, and the potential to improve nitrogen application efficiency in cropping systems utilizing sugarcane.

Effect of Blotong Compost Bio Fertilizer on Early Growth of Sugar Cane (Saccarum Officinarum)

Bio-compost can help increase water holding capacity, because in addition to containing a lot of organic matter, it also makes the soil hygroscopic and the structure becomes crumbly. Giving Blotong bio-compost at a dose of 80 tons / ha is very good because it increases the development of sugarcane roots and can increase production. The purpose of the study was to determine the effect of bio-compost blotong on the growth of sugarcane (Saccharum officinarum). The research was conducted in the field of Tegal which is located in the village of Blabak, Kandat sub-district, Kediri Regency. altitude of 100 masl. This research was carried out in the field using a one-factor Randomized Block Design (RAK) where the treatment factor was blotong dose: B0 = 0 tons ha-1, B1 = 5 tons ha-1, B2 = 10 tons ha-1, B3 = 15 tons ha-1, B4 = 20 tons ha-1, B5 = 25 tons ha-1. Parameters of observations made consisted of: Growth Percentage, Plant height, Number of leaves, Number of tillers, Stem diameter. The results of the research on the treatment of Blotong bio-compost fertilizer were significantly different, with the highest percentage of plant shoot growth at a dose of 20 tons ha-1, which was 89.17%. Plant height with a dose of 20 tons ha-1 is 94.75 cm. The highest number of leaves of the plant was 16.25 cm. The highest number of tillers of the sugarcane plant was 9.22 stems, the diameter of the stem of the highest sugarcane plant was 15.95 cm.

El Nino/La Nina and IOD impact on Kharif season crops over western agro-climatic zones of India

Climate modes like ENSO (El Nino Southern Oscillation) and IOD (Indian Ocean Dipole) produce an impact on the monsoon rainfall over India. Monsoon rainfall is extremely important for the agriculture of our country. The impact of these climate modes on monsoon rainfall thus in turn affects the rain-fed crops (kharif). In this study, four kharif season crops namely rice (Oryza sativa), maize (Zea mays), pulses and sugarcane (Saccharum officinarum) are chosen over four arid/semi-arid agro-climatic zones of western India to study the effect of the climate modes on selected crops. The detailed analysis has been carried out to show the impact of rainfall in the El Nino/La Nina (phases of ENSO) and IOD years on the crop productions over the mentioned zones viz. (Central plateau and hills region; Western plateau and hills region; Gujarat hills and plains region; Western dry region) from 1966–2011. The results show that rice productions which require hot and humid conditions have been largely affected during drought years associated with El Nino which results in poor rainfall over all the zones. The production of pulses which does not require excess humid conditions shows marginal improvement during the neutral years or non-El Nino/non-La Nina years. Maize production seems to be better in La Nina years and worst in the El Nino years as La Nina years are responsible for good rainfall in all zones. El Nino years provide a minor impact on sugarcane productions in different zones. La Nina years are well suited for sugarcane production in all zones of our study as sugarcane requires a good amount of moisture. Positive IOD years are associated with poor crop productions as compared to negative IOD years mostly in all zones as most of the positive IOD years happen to be El Nino years. El Nino-rainfall relation being dominant than positive IOD-rainfall relation is, therefore, responsible for negative rainfall anomalies over the selected zones.

Agronomic and biochemical attributes and economic indices of sugarcane (Saccharum officinarum) in saline vis-a-vis non-saline soils

The study evaluated the yield and biochemical attributes of eight sugarcane (Saccharum officinarum L.) cultivars (CoPb-18211, CoPb-18212, CoPb-18213, CoPb-18214, CoPb-19211, CoPb-19212, CoPb-19213 and CoPb-19214) in saline and non-saline soils during 2019–20 at Punjab Agricultural University, Punjab farms at village-Ruldu Singh Wala (Bathinda) and at village-Ratta Khera (Sri Muktsar Sahib). Soil salinity significantly (P&lt;0.05) decreased the plant height (by ~66.6%), tillers/plant (~36%), cane diameter at ground surface (~79.8%) and diameter at breast height (~93.1%) than the non-saline soil. Soil salinity significantly decreased the TSS content in juice (by ~7.1%), sucrose (~55.6%) and titratable acidity (~11.0%) than the non-saline soil. Juice purity showed large variation in saline soils (37.9-98.7%) than the non-saline soil (88.9–96.4%), and was significantly lowest for CoPb-18213, and highest for CoPb-18214. Sugar recovery was decreased by ~21.4% in saline soil. Average gross returns were significantly higher for CoPb-19211, compared with the others. Mean economic efficiency of 7.78 US$/ha/d for saline and 9.13 US/ha/d showed ~17.2% increase for non-saline soil.

Growth and Production Performance of Sugar Cane (Saccharum officinarum L.) Clon SB 01, SB 04, sb 19, SB 20 in the Village Curahmalang, Jombang Regency

Sugar productivity decreased in 2015-2016 by 11.76% and reached the lowest productivity in 2017 of 4,985 kg/ha White Crystal Sugar (GKP). The reason could be due to the presence of several types of sugarcane that experienced a decrease in yield during cultivation, such as nutrient deficiencies which resulted in divergent sugarcane plant height. Then the low sugarcane juice contained in sugarcane plants also affected production results. This study aimed to determine the growth and yield performance of sugarcane (Saccharum officinarum L.) clones SB01, SB04, SB19, SB20. This research was conducted in the garden of the Center for Sugarcane Research and Development (P3T) Faculty of Agriculture, University of Muhammadiyah Gresik, PG GEMPOLKREP and PT Perkebunan Nusantara X (PTPN X). Sumobito District, Jombang Regency from March to June 2021. Materials for observations used clones SB 01, clones SB 04, clones SB 19, and clones SB 20. The variables observed were sugarcane shoots, sugar cane stalks, and sugarcane leaves. Data analysis used descriptive analytical, variability and heritability.
