Causation studies for Kapas yield, yield components and lint quality traits in Mexican cotton (Gossypium hirsutum L.)

Cotton is a very important crop that consists of traits with different associationship due to genetic and environmental factors. In order to determine the degree of association between seed cotton yield and important traits, a study was done using an RBD experiment with 30 hybrids. Seed cotton yield, plant height, GOT, number of sympodial braches, boll weight, bolls per plant, span length, fineness and strength data were collected and analysed. The experiment was done with 30 F1 hybrids have delivered through Line x Tester mating configuration utilizing six lines and five testers were planted in a Randomized Block Design (RBD) with two replications at the Department of Cotton, TNAU, Coimbatore. Seed cotton yield per plant was found to have significant positive genotypic connection with boll weight (0.5810), number of bolls per plant (0.3867), plant height (0.422) and ginning percent (0.2182) however altogether and contrarily related with consistency proportion at genotypic level. The phenotypic relationship esteems likewise uncovered that seed cotton yield per plant had highly huge and positive phenotypic connection with number of bolls per plant (0.3470) and boll weight (0.4763). Path coefficients were processed to assess the commitment of individual characters to yield in cotton. The way investigation demonstrated high certain immediate impact of number of bolls per plant (0.4743) and fiber strength (0.6880) on seed cotton yield. Micronaire value displayed high sure circuitous impact on seed cotton yield through range length (0.3393), the outcome showed that number of bolls per plant had a high sure relationship with seed cotton yield and sympodial per plant recorded low certain connection with seed cotton yield. It was therefore concluded that selection of high yielding cotton hybrids could emphasize more on lint yield, boll weights, plant height and bolls per plant for better-performing lines. Gin outturn and fibre strength could be used indirectly to improve seed cotton yield through other traits.

Soil application of boron impacts its solubility, yield and fibre quality of cotton in calcareous soils of North-western India

Aim: To investigate that application of boron (0-2.5 mg kg-1 soil, as borax and granubor) to calcareous soil in North-western India affectes its solubility in soil, yield and fibre quality characters of cotton (Gossypium hirsutum L.). Methodology: A field study was conducted to estimate and enumerate the influence of B application (as borax and granubor @ 0-2.5 mg B kg-1 soil; B0-B2.5) on cotton yield and yield contributing attributes ascribed to change in different fractions of variable solubility in B deficient (available B=0.21 mg kg-1) calcareous sandy loam soil. This field experiment was set up in a plot size of 2.7m X 3.75 m with three replications arranged in RBD in factorial combinations. Results: Mean lint and cotton seed yield increased significantly under B1.0, compared with control (B0). Boron concentration in roots, leaves, petioles, bolls, sympodial and monopodial branches, seeds and lint increased significantly (p<0.05) with 1.0 mg B kg-1 application (B1.0). Boron application (B2.0) significantly augmented the mean uniformity ratio by ~4.8%, compared with B0, while the fibre strength and staple length increased significantly in B1.5 treatment. The micronaire value of lint decreased significantly from 4.84 (in B0) to 4.25 µg inch-1 in B2.5 treated plots. Boron application caused notable augmentation in B concentration in its reservoirs/pools of variable solubility; oxide bound fraction being smallest (~0.34% of total B), while residual B the largest fraction (~95% of total B). Boron sources had meagre affect and did not vary remarkably for B concentration in different vegetative plant parts, cotton yield and contributing attributes and B fractions of variable solubility in calcareous soil. Interpretation: The findings of study divulged that soil applied B significantly augmented cotton yield and its yield contributing attributes owing to augmented solubility of B in a calcareous soil. Different B fractions evinced a significant (p<0.05) relationship with yield attributes, indicating their significance for increased B uptake which impacts the seed cotton yield in a calcareous soil. These experimental outcomes highlight the overwhelming significance of soil application of B for increased cotton productivity with improved fibre quality.

Evaluation of Pelvic Floor Muscle Function(PFMF) In Cervical Cancer Patients With Querleu-Morrow Type C Hysterectomy: A Multicenter Study

Introduction To evaluate the pelvic floor muscle function (PFMF) of cervical cancer patients after type QM-C hysterectomy and to explore the relationship between decreased PFMF and related factors..Methods This was a multi-centered retrospective cohort study. 181 cervical cancer patients who underwent type QM-C hysterectomy were enrolled from 9 tertiary hospitals. Strength of PFMF were measured by using neuromuscular apparatus (Phenix U8, French). Risk factors contributing to decreased PFMF were analyzed by univariate and multivariate ordinal ploytomous logistic regression. Results Totally 181 patients were investigated in this study. 0-3 level of type I muscle fibre strength(MFSI) was 52.6% (95/181), 0-3 level of type ⅡA muscle fibre strength(MFSⅡA) was 50% (91/181). Subjective stress urinary incontinence was 46%(84/181), urinary retention was 27.3% (50/181), dyschezia was 41.5% (75/181), fecal incontinence was 9%(18/181). ① MFSI：Multivariate ordinal ploytomous logistic regression shows that the follow-up time(p<0.05), chemotherapy and radiotherapy (p=0.038) are independent risk factors of MFSI’s reduction after type QM-C hysterectomy. ② MFSⅡA：Multivariate ordinal ploytomous logistic regression shows that the follow-up time (p<0.05) are independent risk factors of MFSⅡA’s reduction after type QM-C hysterectomy. The pelvic floor muscle strength (PFMS) increased after 9 months than in 9 months after operation, which showed that the PFMS could be recovered after operation. Conclusions We advocate for more attention and emphasis on the PFMF of Chinese female patients with cervical cancer postoperation.Contribution of the Paper PFMF after QM-C hysterectomy has not been analyzed by current study. The contribution is that patients with radical hysterectomy should do pelvic floor rehabilitation exercises in 3 months after operation.

Composite paper from an agricultural waste of bagasse sugarcane and pineapple leaf fibre: a novel random and multilayer hybrid fibre reinforced composite paper

Bagasse sugarcane (BSC) has low fibre strength due to low cellulose content. Hence, by adding a strong secondary fibre that is high in cellulose such as pineapple leaf fibre (PALF), the fibre strength of the system can be improved. High portion of PALF decreased the composite paper performance because the high composition of PALF tends to produce flocs and agglomerates fibres. The arrangement of the fibres in composite paper should be improved so that this agglomerate’s effect could be overcome. A novel multilayer hybrid fibre composite was used. BSC/PALF with several hybrid ratios was studied in terms of the mechanical and moisture properties of the produced paper sheet and the results showed that multilayer hybrid composite paper produced higher in hybrid composite paper’s properties compared with random hybrid composite paper. The colour of multilayer hybrid fibre composite paper resembled the natural bright colour of BSC and the multilayer hybrid fibre composite paper also shown a slightly low weight loss percentage compared with the random hybrid fibre composite paper after 60 days of soil burial test. As a conclusion, multilayer hybrid fibre composite produced the stronger interfibre bonding and overcome the agglomerate’s effect between BSC/PALF compared with random hybrid fibre composite.

Comparison Study on Fiber and Cocopeat from Young Coconut Husks and Old Coconut Husks

Fiber and cocopeat are waste products from coconut husks that can be turned into value added products. Fiber and cocopeat from old coconut husks are well known in coconut industry in the world. This paper described fibre strength from young coconut husks, nutrient content and water-holding ability of young coconut cocopeat compared to old coconut cocopeat. The strength of fiber was determined by using Instron Universal Testing Machine. The results showed that mean load at break for young coconut fiber was 13.76 N while mean load at break for old coconut fiber was 14.93 N. Maximum tensile stress for young coconut fiber was 1.55 MPa and 1.76 MPa for old coconut fiber. The nutrient contents were determined for young cocopeat and old cocopeat resulted as phosphorus (372.79 ppm, 339 ppm), potassium (6829.68 ppm, 10040.46 ppm), calcium (508.74 ppm, 578.40 ppm), magnesium (468.67 ppm, 715.60 ppm) and sodium (1579.70 ppm, 3917.60 ppm). The pH value was 6.55 and 5.39 respectively. The ash contents were 2.62% for young cocopeat while 4.06% for old cocopeat. For water holding ability test, moisture content of each sample from young coconut cocopeat and old coconut cocopeat was determined by using soil moisture meter. After seven days with water added 500 ml two times/day, results showed that water holding ability for peat moss was the best while young cocopeat was better than the old cocopeat. All the results showed that fiber and cocopeat from young coconut husk have high potential for sustainable production in the coconut industry.

Assessment of production potential of long-linted Gossypium arboreum L. genotypes under different sowing times

Background Gossypium arboreum is one of the cultivated diploids which has inherent resistance against insect pests and diseases, can withstand moisture stress, needs less nutrients and is suitable for erratic, less rainfall and marginal soils. Due to its smaller boll size and poor locule retentivity, adoption of species by farmers is very low. So, best long-linted G. arboreum genotypes with high yielding potential and suitable sowing time will be identified for rainfed tracts of cotton cultivated areas in India. Results The pooled analysis results found that the significantly highest mean seed cotton yield was recorded with Phule Dhanwanthry (1069 kg/ha) which was on par with K12 (1027 kg/ha), DLSA 17 (977 kg/ha) and PA 812 (951 kg/ha). Planting at 4 August yielded the significantly higher seed cotton yield (1345 kg/ha) in comparison with 4 September sowing (536 kg/ha). The interaction results in pooled data revealed that Genotype PA 812 planted at 4 August registered the significantly highest seed cotton yield (1487 kg/ha) which was on par with all genotypes sown on 4 August except PA 402. Amongst long-linted genotypes, PA 760 recorded the significantly highest upper half length (29.9 mm), mean length (24.9 mm) and fibre strength (27.0 g/tex) and fibre quality index (349.7); which was on par with DLSA 17, PA 812 and PA 402. The quality characters had not been influenced significantly by different times of sowing. Conclusions The results concluded that the significantly highest mean seed cotton yield was recorded with Phule Dhanwanthry (1069 kg/ha) which was on par with K12 (1027 kg/ha), DLSA 17 (977 kg/ha) and PA 812 (951 kg/ha). Planting at 4 August found that the significantly higher seed cotton yield (1345 kg/ha) in comparison with 4 September sowing (536 kg/ha). Amongst long-linted genotypes, PA 760 recorded the significantly higher fibre quality index (349.7)

Fibre and Seed Productivity of Industrial Hemp (Cannabis sativa L.) Varieties under Mediterranean Conditions

Farmers’ interest in renewable raw materials such as hemp (Cannabis sativa L.) fibres has recently increased, but hemp productivity is strongly affected by genotype and environment conditions. A 3-year field experiment was conducted under Mediterranean environment in northern Greece to evaluate the productivity (regarding fibres and seeds) of six monoecious hemp varieties. The vars. Futura 75 and Bialobrzeskie provided the greatest (p < 0.01) fibre productivity (4.57 and 4.27 t ha−1, respectively), which were 77.1% and 65.5%, respectively, greater than that of the least productive var. Fedora 17. However, the vars. Santhica 27, Tygra and Bialobrzeskie provided the highest (p < 0.05) seed yield (2.7, 2.9 and 2.6 t ha−1, respectively), which were 28.6%, 38.1% and 23.8%, respectively, greater than that of the least productive var. Futura 75. Hemp fibre yield was strongly positively correlated with total biomass (R2 = 0.8612) and stem biomass yield (R2 = 0.9742), while it was inversely correlated with fibre strength (R2 = 0.424). Hemp seed yield was not correlated with the hemp plant density, height, total biomass or stem biomass yield. The six hemp genotypes evaluated in the study had Δ9-tetrahydrocannabinol (THC) content lower than 0.2% satisfying the European legislation requirements for industrial hemp varieties. The results of the study indicated that, under Mediterranean conditions (northern Greece), the var. Bialobrzeskie showed high productivity, as averaged across years, for both fibres and seeds. This result is very helpful for farmers which should prefer hemp varieties of dual-purpose production (stems and inflorescences or stems and seeds) adapted best to their local environment.
