Fibre Yield

Linseed (Linum usitatissimum L.) grown for seed does not compete well with flax in fibre yield, but as a by-product of seed production its stems could be used in non-woven products. With the aim of discovering suitable linseed genotypes to be cultivated for dual-purpose use in Finland, Finnish linseed cv. Helmi was compared with ten other linseed genotypes and one flax cultivar for stem yield, bast fibre content in stem, stem length and diameter and bast fibre yield. In addition, breaking tenacity and elongation at break of the fibres were determined. The experiments were carried out in 1996B1997 at the Agricultural Research Centre (MTT) in Jokioinen, Finland (latitude 60o49'N). Bast fibre content in stem averaged 16.9% and breeding line Bor 18 had significantly higher bast fibre content than cv. Helmi. Bast fibre yield averaged 301 kg dry matter ha-1. Compared with cv. Helmi, breeding lines Bor 15 and Bor 18 and cvs. Flanders and Gold Merchant produced significantly higher fibre yield. The median for breaking tenacity varied among the genotypes between 41 and 67 cN/tex and the median for elongation at break between 3.5 and 6.8%. Finnish breeding line Bor 18 is recommended for cultivation as dual-purpose linseed in Finland. ;

AbstractCommon bean (Phaseolus vulgarisL.) is amongst the most important grain legume crops in Africa in general, and Ethiopia in particular. The Mexican been weevil (Zabrotes subfasciatusBoheman) heavily attacks the grain of common bean. A total of 300 common bean entries were subjected to a ‘no-choice’ test at Melkassa Agricultural Research Centre, Ethiopia, using a randomized complete block design with three replications, to evaluate for resistance to the Mexican bean weevil. Data on insect and seed traits were collected and a significant level (P<0.01) of variation in all parameters measured was observed amongst genotypes. Relative resistance was recorded in landraces, improved genotypes and breeding lines, but the resistant genotypes, RAZ-11, RAZ-36, RAZ-2, RAZ-44, RAZ-120, RAZ-40 and MAZ-203, showed consistently complete resistance, with zero index of susceptibility value. Two other promising entries were also identified from the breeding lines (SCR-11) and landrace collections (NC-16) of Ethiopia. Stratified ranking diagrams showed that accessions from different eco-geographical origins in Ethiopia and those with different colours showed different patterns of response to infestation. The Ethiopian bean breeding programme should take up the resistant genotypes for a comprehensive yield trial at the national level and direct release them as commercial varieties. The incorporation of bean weevil resistance genes into adapted varieties through backcross breeding techniques, supported with marker assisted selection, seems to be the best strategy not only in terms of time saving but also in terms of effectiveness and efficiency.

In the resent years evaluation and conservation of genetic recourses becomes of great importance. Some of the genotypes could be lost when un-sufficient attention is given to them. Some old (created before WWII) Latvian flax accessions have been investigated at the collection nursery at the Upytė Experimental Station of the Lithuanian Research Centre for Agriculture and Forestry in 2007-2010. Phenological phases, plant height, flower colour, stem, seed and long fibre yield, fibre content and quality (flexibility, strength, quality number), duration of vegetation period, resistance to lodging, etc., have been investigated. The most valuable genotypes have been suggested to be used in further breeding programs.

Cheng, B., Rakow, G., Olson, T., Williams, D. J. and Gugel, R. K. 2015. AAC Adagio yellow mustard. Can. J. Plant Sci. 95: 1043–1045. Mucilage content in yellow mustard (Sinapis alba L.) is an important seed quality parameter for the mustard trade since mucilage contributes to the consistency of prepared mustard products. Some wild type brown-seeded accessions of S. alba have much higher mucilage contents than have been observed in yellow-seeded cultivars and breeding lines. Increasing the mucilage content of cultivated, yellow-seeded S. alba by transferring the high mucilage trait from brown-seeded S. alba was initiated in 2004 at the Saskatoon Research Centre, Agriculture and Agri-Food Canada. The yellow mustard variety AAC Adagio with high mucilage content [96.8 centistokes (cst) g−1 seed] was successfully developed from crosses between the elite yellow-seeded breeding line SA00-PYM (mucilage: 35.2 cst g−1 seed) and five brown-seeded S. alba accessions (mucilage: 87.5–108.7 cst g−1 seed). AAC Adagio is well-adapted to all mustard growing areas of western Canada.

Flax is cultivated on small areas in Latvia. Flax gives dual-purpose production – fibre and seeds. Latvian flax has a high fibre and seed quality. The quantity of flax fibre and seed yield depends on many factors. Several qualitative and quantitative traits, such as technical stem length, resistance to lodging, vegetation period, yield of straw and seeds, fibre and oil content and quality were evaluated. For the further development of Latvian economy flax varieties and hybrids of Latvian origin are an important goal. Fibre flax varieties 'Blue di Riga', 'Priekuļu 665', 'Ošupes 30' and breeding lines 'S-64-17-93' and 'L11-11/11-94' are valuable material containing a qualitative and quantitative indicators of variety. 92 Latvian accessions of flax hybrids have been evaluated, and 12 accessions with the best seed and straw yield have been selected for further DNA analysis. This will simplify and accelerate the selection of new valuable hybrids that will provide particular advantages in agriculture. The genetic analysis of DNA determines the kinship and diversity of flax varieties and breeding lines which can be used further in flax breeding.

The study was conducted to know the performance of growth, yield contributing parameters and yield of seven white Jute breeding line and two checks (CVL-1 and CVE-3) at five different jute research regional stations of Bangladesh Jute Research Institute (BJRI) during the period from March to September 2014. The experimental data was laid out in a completely randomized block design with three replications and the means were adjudged by DMRT at 5% level of probability. The performances of experimental lines were showed statistically significant variation among the studied whole growth, yield and yield attributing traits. Analysis of variance revealed significant differences among the treatments for fibre yield and stick yield at Rangpur plant height, base diameter, fibre and stick yield at Manikganj plant height and fibre weight at Chandina, Faridpur and plant height at Kishoreganj. It was revealed by the pooled mean performance that among the genotypes, the line C-5018 m produce the tallest plant among the lines. The Line C-5030 recorded both the highest plant population (0.241 m/ha) and base diameter (21.79 mm). The line C-5133 showed highest Green weight with leaves (43.12 t/ha) whereas C-5149 recorded the greatest Green weight without leaves (35.02 t/ha). The most important parameter is the fiber yield and the highest-fibre weight (2.83 t/ha) was recorded by the line C-5149 among the seven breeding line. The line C-5149 also recorded the highest amount of stick yield (6.01 t/ha). However, pooled mean over stations revealed that no progenies, C-5018, C-5030, C-5036, C-5044, C-5133, C-5136, C-5149 out-yielded both the check varieties CVL-1 (2.83 t/ha) and CVE-3 (2.54t/ha) whereas C-5149(2.83t/ha) shows the equivalent result as CVL-1. It was also revealed that C-5030(2.61t/ha), C-5136(2.70t/ha) and C-5149(2.83t/ha) out yielded check variety CVE-3 (2.54t/ha). Progressive Agriculture 31 (1): 19-25, 2020

Advanced oat breeding lines were investigated in 2009-2011 at the Institute of Agriculture of Lithuanian Research Centre for Agriculture and Forestry. The highest grain yield (4.10 t ha-1) and fat content (4.41%) was in 2009 and the highest protein and starch content (12.54% and 51.4%) was in 2011. Every year the yield of oat line LIA 1526-9 was higher or similar to the standard variety yield. The breeding line LIA 1526-9 also gave good results for fat, protein and starch yield. Every year fat, protein and starch content of naked line 1579-1 was higher in comparison with standard variety Mina DS: respectively, 7.39%, 12.6%, and 61.7% (standard variety 6.49%, 12.3%, and 55.7%) in 2009, 6.27%, 15.1%, and 60.7% (standard variety 5.06%, 11.5%, and 52.8%) in 2010 and 6.24%, 15.1%, and 63.6% (standard variety 5.66%, 14.0%, and 58.4%) in 2011. Significantly higher yields of fat, protein and starch per hectare were obtained in 2009 and reached 176, 454, and 1910 kg ha-1. Fat, protein and starch yields per ha of naked oat breeding lines were not higher than those of hulled oat breeding lines because of their low grain yield.

SUMMARYA decline in supplies of organic manures and the increased use of chemical fertilizers has led to a decrease in the micronutrient content of the soil, with attendant effects on yield.Field studies were conducted in 1986 and 1987 at the Giza Agricultural Research Centre, Egypt, to determine the effect of Cu-EDTA and Mn-EDTA foliar sprays on growth, mineral content, yield components and fibre properties of the Egyptian cotton cultivar Giza 75 (Gossypium barbadense L.).All combinations used significantly increased the uptake of Cu and Mn and the dry matter yield. The earliness of harvest and the value of yield components were all increased by the application of Cu or Mn; 25 mg/1 of both Cu and Mn gave the highest values. Lint percentage and fibre properties were not significantly affected.This study indicated that the yield of cotton, grown under otherwise standard conditions, may be increased by foliar sprays of Cu-EDTA and Mn-EDTA combined.

Kenaf is a multi-purpose crop with numerous industrial uses. Its production is constrained by poor cultural and agronomic practices which reduce yield. Inappropriate spacing among others could result in low yield. Effect of plant spacing on growth and yield of kenaf was investigated in Ibadan, Nigeria. Kenaf seed was sown (2 plants/stand) at three plant spacing: 50×15, 50×20, 50×25 cm was assessed for seed and bast fibre yields using randomized complete block design (RCBD) with three replicates. The analysis was done using statistical analysis system (SAS). Plant spacing differed significantly for bast fibre and seed yields. Highest bast fibre yield (0.9±0.03) and seed yield (0.5±0.01) were obtained at 50×20 cm and 50×25 cm spacing, respectively, while the lowest bast fibre yield (0.7±0.01) and seed yield (0.3±0.01) were obtained at 50×15 cm spacing. Spacing of 50 × 15 cm and 50 × 20 cm are appropriate when planting for fibre while 50 × 25cm is appropriate for seed production. Keywords: Kenaf, Spacing, Fibre and Seed yield.

A field experiment was conducted at Regional Wheat Research Centre of the Bangladesh Agricultural Research Institute, Joydebpur, Gazipur for 2 consecutive years during 2006-07 and 2007-08. The objectives were to find out the optimum nutrient management practice on tuber yield, nutrient balance and economics of potato cultivation. Twelve nutrient management treatments were tested in a randomized complete block design with 3 replications. Treatments were T1=HYG (0-198-44-194-24-6-1.2), T2=MYG (0-140-34-138-18-4.5-0.9), T3=IPNS (10000-168-38-170-18-6-1.2), T4=STB (0-171-40-164-22-5-1), T5=FP (0-97-16-91-0-0-0), T6=CON (0-0-0-0-0-0-0), T7=HYG+CRI, T8=MYG+CRI, T9=IPNS+CRI, T10=STB+CRI, T11=FP+CRI, T12=CON+CRI kg ha-1 CDNPKSZnB for potato. The highest tuber yield of potato was obtained from STB+CRI (27.64 t ha-1) followed by IPNS+CRI (27.35 t ha-1), STB (27.10 t ha-1), IPNS (26.83 t ha-1), HYG+CRI (26.52 t ha-1) and HYG (26.10 t ha-1) in 2006- 07. Similar trend was found in 2007-08. The highest tuber yield and yield contributing parameters were noticed in CRI plots than without CRI. Except N, remaining nutrient balance like P K S Zn and B were found positive in case of HYG, MYG, IPNS and STB along with or without CRI nutrient managements. The balance was found almost negative in case of FP and CON. The highest BCR was observed in STB+CRI (3.96) followed by STB (3.93), IPNS+CRI (3.76), and IPNS (3.74). The higher gross return (Tk. 283331 ha-1) and also gross margin (Tk. 211761 ha-1) was observed from the same treatment. DOI: http://dx.doi.org/10.3329/bjar.v39i4.22544 Bangladesh J. Agril.
