SUMMARYForty-six cultivars of linseed oil (Linum usitatissimum L.) were grown under wet and dry season conditions in the Sudan Savanna of Nigeria. Only during the dry season was production good and cv Dunes consistently outyielded all other cultivars in terms of seed and oil content. Trials of sowing dates gave maximum seed yield and oil content from plots sown during late October. In row spacing trials, rows 15–22 cm apart and seed rates of 58–78 kg/ha were found to be the most practicable. There was a linear relation between increasing rates of nitrogen and seed yield, maximum production being obtained at 55–88 kg N/ha, but oil content was slightly depressed at levels above 33 kg N/ha.

ABSTRACTThe breeding season and diet of the rat Arvicanthis was monitored from December 1983 to November 1985 in the semi-arid Sudan savanna at Kano, Nigeria, West Africa. Breeding began 1–2 months before the start of the rainy season and ceased at the beginning of the dry season. The diet of Arvicanthis was omnivorous, but with seasonal differences. Monocotyledons and dicotyledons predominated in the diet in the dry season, with seeds and insects increasing in the diet in the rainy season. The major differences between the ecology of Arvicanthis at Kano and on the East African savanna were that in East Africa the breeding season is longer and begins after the start of the rainy season. These and other dissimilarities between the biology of Arvicanthis in the two areas could be due to the effect of climatic differences on food supply and to the possible existence of different taxonomic groupings of Arvicanthis in the two regions.

Milk thistle, Silybummarianum (L.)Gaertn.,is grown throughout the world for its hepatoprotectant flavonolignans, known collectively as silymarin. Silymarin is found primarily in the seeds. Milk thistle was grown outdoor field for determination of plant growth, seed yield under various variants of row spacing (30x20, 40x20 and 50x20) and different sowing dates (May 20, May 30 and June 10). Plant height measured (ranging from 43.5-82.6cm)and yield (ranging from 5.24-70.31cg/ha) that there was a significant difference among different sowing dates and row spacing.Mongolian Journal of Agricultural Sciences Vol.13(2) 2014: 73-75

Seed Characteristics

Five flax (Linum usitatissimum L.) cultivars, Dufferin, McGregor, Linott, NorLin and NorMan were grown in the field in 1985, 1986 and 1987 at seeding rates of 200, 400, 600 and 800 seeds m−2. Averaged over all cultivars and years, as seeding rate increased from 200 to 800 seeds m−2, maturity was hastened 2.1 d, seed weight decreased 0.16 g 1000−1 seeds, oil content decreased 0.6%, iodine number decreased 1.3 units and volume weight was not markedly changed. Lodging increased and basal branching decreased from 1.68 to 0.18 branches per plant as seeding rate increased. Plant height increased 0.6 cm from the 200 to the 400 seeds m−2 rate then decreased 1.8 cm from the 400 to the 800 seeds m−2 rate. Seed yield increased from 110 to 124 g m−2 as seeding rate increased from 200 to 600 seeds m−2, then decreased to 121 g m−2 at 800 seeds m−2. Although yields of the five cultivars varied somewhat in their response to seeding rate and year, most yielded near optimum at the 600 seeds m−2 seeding rate.Key words: Flax, Linum usitatissimum L., seeding rate, lodging

CDC Neela, a medium–late-maturing oilseed flax (Linum usitatissimum L.), was released in 2013 by the Crop Development Centre, University of Saskatchewan, Saskatoon, Saskatchewan. This cultivar has medium oil content, medium oil quality, medium seed size, good lodging resistance, and high seed yield in all soil zones of the Prairies. It is immune to North American races of rust caused by Melampsora lini, and moderately resistant to wilt caused by Fusarium oxysporum f. sp. lini.

Sowing Dates

The sowing date is an important factor for expanding the cultivated area of rapeseed and affects seed yield, oil content, and fatty acid compounds. Micronutrient elements play an important role in improving the vegetative and reproductive growth of the plant, especially under conditions of biological and environmental stresses. A two-year experiment (2014-2016) was performed to study the response of rapeseed genotypes to foliar application of micronutrients on different sowing dates. The treatments were arranged as a factorial-split plot in a randomized complete block design with three replicates. Three sowing dates of 7 (well-timed sowing date), 17, and 27 (delayed sowing dates) October and two levels of foliar application with pure water (control), selenium (1.5%), zinc (1.5%), and selenium+zinc (1.5%) were factorial in the main plots and five genotypes of SW102, Ahmadi, GKH2624, GK-Gabriella, and Okapi were randomized in the subplots (a total of 30 treatments). Seed yield, oil yield and content, oleic acid, and linoleic acid were reduced when rapeseeds were cultivated on 17 and 27 October, while the contents in palmitic, linolenic, and erucic acids, and glucosinolate increased (p < 0.01). a selenium+zinc treatment improved seed yield, oil content and yield (p < 0.01). The oil quality increased due to increased contents of oleic and linoleic acids under the selenium+zinc treatment (p < 0.01). The GK-Gabriella and GKH2624 genotypes are recommended to be sown on well-timed (7 October) and delayed sowing dates (17 and 27 October) and treated with selenium+zinc due to the higher oil yield, linoleic and oleic acids.

The influence of the level of mineral nutrition and rate of seed sowing on yield and fatty acid composition of linseed (Linum usitatissimum L.) in the Non-chernozem zone of Russia was studied. It was shown that the level of mineral fertilizers N - 90, P2O5 - 60, and K2O - 60 kg/ha under the rate of sowing of 8 million seeds/ha provided maximum seed yield of 1.94 t/ha. A clear correlation between oil content and rate of sowing has not been established. Under an increasing level of mineral nutrition, oil content was slightly increased. The composition of oil was slightly changed under the influence of the studied factors.

The aim of this study was on the basis of the field experiment in two different agroclimatic localities, two planting options (low and high input) and during three years find out the seed yield, seed oil content and composition of fatty acid in linseed oil (Linum usitatissimum L.), variety Lola (LinolaTM). By the help of standard laboratory analyses for paint parameter evaluation judge suitability of using the oil for painting industry. Linseed yield varied from 0.29 t.ha–1 to 2.35 t.ha–1. Statistical significant differences (P = 0.01) were found out for localities, years and planting options. Average seed oil content varied from 36.6% to 44.0%. Influence of locality was not significant, influence of year and planting option to seed oil content was highly significant (P = 0.01). Content of linoleic acid in oil was influenced mainly by locality and planting option and varied from 75.86% to 76.78%. Laboratory painting-technological evaluation of oils and alkyd resin experimental sample made for suitability of using low linolenic oil of linseed, variety Lola for production of non-yellowing alkyds and enamels.

Thirty-six genotypes including eight parents and their 28 crosses developed in diallel fashion excluding reciprocals were used to studied their stability performance over six contrasting environments viz., early, normal and late sown under rainfed and irrigated conditions for seed yield and its contributing characters. Genotype x Environment interaction and Linear component of G x E interaction were showed significant for all the characters except plant height, secondary branches per plant and biological yield per plant under study. The parents Meera and PA2 showed stable performance for two characters and rest of the genotypes showed stable performance for one character over a range of environments under study. The cross Meera x RL13161 and RL15583 x KBA3 showed stable performance for seed yield and two crosses RL13161 x KBA3 and RL15583 x KBA3 showed stable performance for oil content and rest of four crosses showed stable performance for other characters.
