Three faba bean cultivars, Aladin, Herz Freya and Outlook were seeded at three dates (25 Apr, 9 May and 23 May), and at four rates (50%, 75%, 100% and 125% of the recommended rate of 46 plants m−2) atone location (Winnipeg) for 2 yr (1983, 1984). Analysis of variance for yield indicated that both seeding date and seeding rate were very highly significant (P = 0.001). The early seeding date resulted in significantly higher yield and total dry matter and the greatest number of pods per plant. The 50% seeding rate resulted in significantly lower yield and total dry matter, but the highest seed weight and the greatest number of pods per plant, as well as the greatest number of days to maturity. The 75%, 100% and 125% seeding rates resulted in equivalent yield and total dry matter, but significantly fewer pods per plant and reduced seed weight as seeding rate increased. Increased seeding rate partially compensated for delayed seeding. Yield reductions of almost 1% a day for each day delay in seeding for the first 2-wk delay and almost 2% a day for each day delay in seeding for the second 2-wk delay were obtained in this study. It is concluded that seeding as early as possible at 75% of the present recommended seeding rate of 46 plants m−2 should maximize return on seeding cost to the grower.Key words: Total dry matter, harvest index, yield components, protein, density effects, faba bean

Two small faba bean (Vicia faba L.) cultivars, Erfordia and Wiselburger Kleinkornige, were tested at one location for 1 yr at three row spacings (15, 23 and 31 cm) and three seeding rates (100, 150 and 200 kg/ha). The effects of four seeding dates were evaluated for both cultivars. Seeding commenced on 2 May and was repeated at approximately 2-wk intervals. The narrowest row spacing produced the highest seed yield for both cultivars. Row spacing did not affect the protein content, but did affect the percent germination in the cultivar Kleinkornige. The narrowest row spacing (15 cm) produced the highest germination. Seed yield increased with seeding rate for the cultivar Kleinkornige. However, there was no increase in seed yield for the cultivar Erfordia when seeding rate increased from 150 to 200 kg/ha. Seeding rate did not affect the protein content or germination. Date of seeding had a significant effect on the yield. Delayed seeding significantly decreased the yield for both cultivars. Seeding date did not significantly affect the protein content of the seed. Germination was significantly reduced with delayed seeding.

A field experiment was carried out at University of Dhaka from March to July, 2011 to study the effect of time of sowing on the growth and yield of BARI mung-5. The treatments consisted of three dates of sowing viz. March 15, April 15 and May 15. The crop responded significantly to sowing time and 15 April sowing seeds produced plants having maximum plant height (68.4 cm), leaves/plant (29.33), total dry matter/plant (17.99), branches/plant (8.17), pods/plant (11.33), pod length (8.78 cm), seeds/pod (11.17), 1000 seed weight (46.52 g), seed yield/plant (5.33 g), yield/ha (1.77 t) and harvest index (29.58 %) at harvest. The seed yield decreased by 36.8 and 49.9% when seed sown early (15 March) or late (15 May) due to production of lower yield components.   DOI: http://dx.doi.org/10.3329/jbas.v36i2.12966   Journal of Bangladesh Academy of Sciences, Vol. 36, No. 2, 227-231, 2012

Hayman's diallel cross analysis was employed to investigate the nature of the genetic control and heritability of yield, yield components, and phenological and agronomic characters in F1 and F2 generations of spring faba beans (Vicia faba L.). High-yielding S4 inbred lines from five open-pollinated faba bean cultivars were used as parents to generate complete F1 and F2 diallels. The S5 inbred line parents and the 20 cross combinations were planted in randomized complete block experiments with six replications. All characters in the F1 diallel and in the F2 diallel with the exception of days from planting to maturity met all of the assumptions required for Hayman's diallel analysis. Yield, total dry matter, harvest index, and pods per plant exhibited significant apparent overdominance in both the F1 and F2 diallels. It is concluded that substantial immediate increases in yield and total dry matter could be expected from exploiting the apparent overdominant gene action found for these characters in these crosses via F1 hybrids or synthetics.

Crop yields in Finland are limited by many factors, such as the short growing season and spring drought. Thus earliness is an important breeding goal in Finnish agriculture, and is especially needed in some crops such as faba bean that have a longer growing period than cereals. During 2009-2011, 400 accessions of faba bean (Vicia faba L.) from 34 countries were evaluated for morpho-physiological traits related to drought resistance and the earliest accessions were identified. The four earliest accessions, from Cyprus and Syria, were sown in a pot experiment, together with Kontu and Witkiem Manita (an early-flowering, large-seeded Dutch cultivar) in order to determine days to flowering, podding and maturity under controlled conditions. The experiment was conducted in a randomized complete block design with 3 replicates. There were highly significant differences for all studied traits (p<0.001). Accessions D497, D557 and D505 had significantly faster progress to flowering and podding compared to Kontu. Accession D497 was the earliest genotype with 947 GDD (Growing degree-days to maturity), followed by accession D557 (985 GDD), and Kontu and Witkiem Manita were latest accessions in this study (1165 and 1159 GDD, respectively). The linkage of early flowering and early maturity to large seed size needs to be tested. These accessions may be valuable sources of earliness that could be used in faba bean breeding for short seasons such as those in Finland.

The effects of periods of drought during different phases of reproductive growth of faba bean (Vicia faba L.) cv. Xichang Dabai were investigated in a pot experiment at Xichang Agricultural College, China. Parameters were total dry matter; seed yield; yield components; concentrations of nitrogen, phosphorus, and potassium; and total uptake in different organs. All drought treatments decreased total dry matter production and seed yield per plant. Plants subjected to drought from initiation of pod-set to full pod-set (stage D4) produced 32% less total dry matter and 45% less seed yield than the irrigated control. Mean seed weight was a relatively stable yield component. Statistical analysis indicated that only plants subjected to drought at stages D4 and D5 (drought from full pod-set to maturity) had a significantly (P < 0·05) lower mean seed weight than the control. The nutrient concentration was generally high in the younger or more active organs of faba bean, and comparing the nutrients, the N concentration in leaves, stems, flowers, pods, and grain was greatest, followed by K concentration, and P concentration was least. All soil drought treatments decreased the nutrient concentration in various organs after 17–19 days of drought. However, the decreases at maturity were less clear, except the nutrient concentrations in stems and leaves. Water deficit significantly decreased total grain nutrients per plant, the decreases being 34–45% for N uptake, 34–47% for P uptake, and 33–46% for K uptake. Simple linear correlations with the P and K concentration in leaves at maturity and number of pods and seeds per plant gave a correlation coefficient (r) of 0·804–0·874.

Number Of Branches

Variability in 66 accessions of faba bean (Vicia faba L.) was assessed for different agro-morphological and quality parameters. Variability parameters, correlation coefficients, clustering and PCA were performed for yield and its contributing parameters. A very good variability was found in number of branches per plant ranged from 5.4 to 14.4, number of nods per main branch from 10.22 to 26.31, no. of pods in main branch varies from 8.61 to 19.65, 1000-seed weight from 271.69 to 390.31and seed yield per plant varied from 31.32 to 100.3.The protein content (%) of the genotypes varies widely from 26.31 to 31.52.Positive and significant correlation coefficients were also obtained between grain yield and 1000-seed weight (r = 0.33**) and number of pods in main branch (r = 0.01*). Principal Component Analysis shows that PC5 explained 62.8% of the total variance and was most closely associated with number of pods per cluster.

Medicago Sativa L

The effects of cultivars, date and rate of seeding on the yield and quality of alfalfa (Medicago sativa L.) seeded at the end of summer and harvested the year after was studied from 1971 to 1975 on a Kamouraska clay. Seeding in early August gave the best results; seeding should not be carried out after mid-August. Differences between cultivars were more important on the third than on the first cut. Aftergrowth was an important factor on yield during the first year of harvest. Seeding rate did not always affect the yield, but the 6,7 kg/ha rate yielded less than the 13,4 kg/ha rate at the first cut and when the cuts were summed. The combined effects of the three factors studied indicates the importance of the seeding date on the height, cover and yield of alfalfa. Digestibility and crude protein content of the dry matter were affected more by seeding dates than by cultivars. The effect of cultivars on quality was variable and seeding rates had no effect. The variation in forage quality may be attributed to a difference in maturity of the plant at harvest, rather than only to the factors studied.Key words: Medicago sativa L., cultivar, date, rate, yield, quality

Main Effects

Five Canada Utility and two Canada Western Red Spring Wheat (Triticum aestivum L.) genotypes were tested at three Central Alberta locations under 18 conditions of seeding management, consisting of six seeding rates (30–180 kg/ha) combined with three seeding dates. Main effects of dates (D), rates (R) and genotypes (G) were significant at one or more locations for grain yield, days to maturity, grain protein percentage and protein yield. Based on the average response of the seven genotypes, early seeding combined with seeding rates of 90 kg/ha or more gave optimum yield with a minimum number of days to maturity. Main effects were not always the same at all locations, implying G × Location interactions. Significant G × R and G × D interactions were recorded for all variables at one or more locations, although their magnitude was not as great as for the main effects. A significant G × R × D effect was also recorded at one or more locations for grain yield, days to maturity and protein yield. Existence of significant G × R, G × D and G × R × D effects suggests that new wheat cultivars, particularly when of novel germplasm type, should be checked for response to variable seeding management at different locations, in order to capitalize on any favorable interactions.

Seeding Date

The effects of seeding date and seeding rate on the agronomic characteristics of five genotypes of Brassica napus L. were studied for 2 yr at two locations in western Canada. Delayed seeding resulted in a significant increase in vegetative and total yield but a significant decrease in seed yield, harvest index, plant density, racemes per plant and racemes per unit area. Seeding date had no significant effect on seed yield per plant, 1000-seed weight and plant height. Increased seeding rate resulted in a significant increase in plant density, and racemes per unit area, but a significant decrease in harvest index, racemes per plant, seed yield per plant and plant height. Seeding rate had no significant effect on seed, vegetative or total yield and 1000-seed weight. There were significant differences due to genotypes for all variables except for total yield and racemes per unit area.
