Bean Yield

Effects of proso millet interference with irrigated dry beans were evaluated in Nebraska over a 2-yr period. Dry bean yield reduction ranged from 12 to 31% from a wild proso millet density of 10 plants m-2. As density increased, dry bean yield reduction could be predicted with a rectangular hyperbola regression model. Ten wild proso millet plants m-2growing with dry beans produced 14 780 to 21 420 seed m-2. Dry bean yields were reduced 41 and 11% in 1990 and 1991, respectively, when wild proso millet removal was delayed 6 wk after dry bean planting. Four weeks of weed-free maintenance were sufficient to provide dry bean yields comparable to plots kept weed free all season.

A field study was conducted during 3 yr to determine the growth and yield response of Pinto, Pink Red and Great Northern dry beans to various doses of imazethapyr. Imazethapyr was applied postemergence at 0, 25, 50 75 100, 150, and 200 g ha−1 to each class of dry bean. Results indicated that these four classes of dry beans responded similarly to imazethapyr. Dry bean injury increased and yields were reduced as dose of imazethapyr increased. At the proposed use dose of 50 g ha−1, imazethapyr reduced yield by 5 to 6%. Imazethapyr at 100 g ha−1 reduced dry bean yield by 10 to 12% and delayed maturity by 3 to 4 d. Benefits of superior weed control attained with imazethapyr should be weighed against potential crop injury when growers consider using imazethapyr in their dry bean weed management programs.

Yield And Yield Components

Water stress is one of the most important yield-limiting abiotic factors for dry beans (Phaseolus vulgaris L.). This study was conducted 1) to identify the effects of different irrigation scheduling on yield and yield components, 2) to define the number and intervals of irrigation water requirements in dry beans and 3) to compare the performances of two dry bean varieties in different irrigation schedules. The experiments were carried out in the fields of the Anatolian Agricultural Research Institute from 1992 to 1996. Two dry bean cultivars, Yunus90 and Karacasehir90, were used to study the effects of five irrigation schedules (S1: High, S2: Medium, S3: Low, S4: High-Low, S5: Low-High rates of irrigation). The results indicated that year (Y) × irrigation regime (IR) interactions were important for yield and yield components. Karacasehir90 was less affected by water stress than Yunus90 when rainfall was low in the growing season. Differences between irrigation schedules were more distinct when rainfall was low. The highest yield and yield component values were obtained from S1, while the lowest values were obtained from S3 and S4. These results showed that water stress after flowering had the most adverse effect on yield. Thus, it is recommended that farmers use supplemental water chiefly after flowering when water sources are limited.

Akter, Z., Pageni, B. B., Lupwayi, N. Z. and Balasubramanian, P. M. 2014. Biological nitrogen fixation and nif H gene expression in dry beans ( Phaseolus vulgaris L.). Can. J. Plant Sci. 94: 203–212. Dry bean (Phaseolus vulgaris L.) is one of the least efficient nitrogen (N2) fixers among legumes (approximately 30 to 50 kg N ha−1). To identify efficient N2 fixers, 22 dry bean genotypes were screened for symbiotic N2-fixation in potted low-N soil in the greenhouse under four treatments: (1) uninoculated, (2) inoculated with commercial Rhizobium leguminosarum bv. phaseoli inoculant Nitrastik-D®, (3) inoculated with commercial Rhizobium inoculant Nodulator®, and (4) fertilizer N added. Expression of nitrogenase reductase (nifH) gene in selected uninoculated genotypes (nodulated by indigenous rhizobia) was quantified by reverse transcription polymerase chain reaction (RT-PCR) to know if expression of this gene was an indicator of N2-fixation. Nitrogen fixation potential varied among the genotypes and between the rhizobia inoculants. Genotypes differed in shoot (5.17 to 8.39 g plant−1) and root (1.71 to 6.44 g plant−1) dry weights, nodule number (0 to 155 nodules plant−1) and mass (0.055 to 0.250 mg plant−1), and N2-fixed (0 to 129 mg N plant−1). Genotypes GH–196, FR 266 and AC Redbond fixed the most N2 (60 to 112 mg N plant−1) with either rhizobial inoculant, and Viva fixed the highest amount (129 mg N plant−1) when inoculated with Nitrastik-D. In contrast, AC Black Diamond, Island, Winchester, AC Polaris, LEF 2RB and SEA 5 had low N2-fixing potential (3 to 23 mg N plant−1) in inoculated treatments. The qRT-PCR analysis indicated that nifH gene expression was 5 fold higher in GH-196 compared to the non-nodulating mutant R99, which further confirmed the high N2-fixation capacity of GH-196. After confirmation in the field, dry bean genotypes with improved N2-fixation potential identified in this study may be used as parents in breeding programs in the development of future cultivars. The nifH gene expression may be used as a rapid test to select dry beans with high N2-fixation potential.

Differences in potato leafhopper (Empoasca fubae Harris) injury symptoms were noted in 22 cultivars or lines of dry beans (Phaseolus vulgaris L.) in a 1991 field trial at North Platte, Neb. Seed yield, biomass, and plant injury symptoms were recorded. The same 22 dry bean cultivars or lines were planted in a split-plot design, with main plots protected (sprayed with insecticide) vs. unprotected (not sprayed) and cultivars or lines as subplots in 1992 and 1993. Significant differences were observed between cultivars/lines for leafhopper injury and yield in all 3 years. `Tacaragua' (black-seeded) and pinto `Sierra' were highly resistant to leafhoppers, with no visual leafhopper injury symptoms in all 3 years. Significant negative correlation coefficients between leafhopper injury symptoms and yield were recorded in the protected (4.50) and unprotected (-0.33) plots in 1993 but only in the unprotected (-0.46) plots in 1992. A cultivar x spray interaction response to leafhoppers occurred in 1992 but not in 1993. The degree of leafhopper injury symptoms varied between years.

The hydration times of 22 dry bean (Phaseolus vulgaris) selections of red kidney, white, and striped varieties were determined. The Lajas red kidney selection duplicates its weight in 7 h, whereas the striped Calima and Rosita Lajas selections duplicate their weights in 10 h. All other selections duplicate their weights in about 12 to 18 h. All bean selections were accepted when they were sensory evaluated for appearance, flavor, and overall acceptability. The red kidney selections Lajas and 1973 (28), the white selections White 117 and White 142, and the striped selections Dominicana #5, Naranjito, Pompadour Dominicana and Galana scored poorly regarding texture (mouth feel) because they were somewhat hard. Texture was the sensory attribute that contributed most to the overall acceptability (r = .92).

The potato leafhopper (PLH), Empoasca fabae Harris is the most important Empoasca species attacking dry beans (Phaseolus vulgaris L.) in North America. The objective of this study was to determine the heritability (h2) of PLH injury based on parent-offspring regression analysis of F3 means on individual F2 plants derived from crosses of pinto `Sierra' (resistant) × great northern `Starlight' (susceptible), and black bean `Tacarigua' (resistant) × `Starlight' (susceptible). Low narrow-sense heritability values of 0.29 ± 0.06 and 0.28 ± 0.10, respectively, were obtained for the above crosses. The low narrow-sense heritability estimates indicated large environmental effects on the expression of PLH injury in dry beans. An allelic test showed that both resistant parents possessed the same genes for resistance.

Close to 80% of dry beans in western Canada are grown in southern Manitoba. A need was identified to develop soil-testing criteria based on local conditions as well as derive an optimum fertilizer rate to alleviate Zn deficiency. Two experiments with a number of dry bean (Phaseolus vulgaris L.) cultivars were carried out between 2000 and 2002 at a number of locations in Manitoba. Each experiment included two trials per year. The first experiment consisted of two foliar application rates of Zn (0 and 0.33 kg ha-1) as main plots and five rates of broadcast and incorporated soil Zn (0, 2.8, 5.6, 8.4 and 11.2 kg Zn ha-1) as sub-plots. The second experiment also included two rates of foliar Zn (0 and 0.33 kg Zn ha-1) as the main plots; however, sub-plots included a control and four Zn products that were broadcast and incorporated at a rate of 5.6 kg Zn ha-1. Soil DTPA-extractable Zn levels varied from 0.38 to 1.14 mg Zn kg-1 soil. Soil Zn applications resulted in a significant increase of Zn in plant tissue levels at 1/10 bloom growth stage, however, actual levels varied, thus, suggesting that a plant tissue critical level will have to be derived separately for each cultivar. Significant seed yield responses were obtained only when DTPA-Zn levels were equal to, or less than, 0.5 mg Zn kg-1. Optimum yields at responsive sites were obtained with 5 kg Zn ha-1 broadcast and incorporated. All products used (Zn mono- and heptasulphate or oxysulphate) performed equally well, except in one case when ZnSO4.H2O exhibited superior performance. Foliar application of a sulphonic acid based Zn product was not always as effective as soil applied Zn products.
