The presence of a below-ground neighbour alters within-plant seed size distribution in Phaseolus vulgaris

The field experiment was carried out with some selected mungbean genotypes viz. IPSA-13, VC-6173A, BU mug 2, BARI Mung-5 and IPSA-12 to observe the effect of 4-days flooding on their growth and yield of mungbean under field conditions at Bangabandhu Sheikh Mujibur Rahman Agricultural University, Gazipur, Bangladesh during September to November, 2011 maintaining 3-5 cm standing water at 24 days after emergence. Days to flowering and maturity delayed in flooded plants over control depending on the genotypes. Flooding significantly reduced Total Day Matters (TDM), number of pods per plant, seed size and seed yield of the mungbean genotypes over control. Considering higher seed yield, larger seed size and less yield reduction relative to control VC-6173A, BU mug 2 and IPSA-13 were found tolerant to soil flooding condition.Bangladesh J. Agril.

The F2 progenies of crosses among three soybean varieties were evaluated with their parents at Ngale Experimental Farm, Ngawi, East Java during the dry season of 2011. The experi-ment was conducted in a randomized block design with three replications. The seeds of each F2 progenies and parents were planted in two rows of 4.5 m long. Plant spacing was 40 cm x 15 cm and each hill contained one plant. Among the characters studied, seed weight per plant, number of pods per plant and days to maturity had the highest coefficient of variability with the means of 52.6%, 48.2% and 41.9%, respectively. Whereas seed size, plant height and number of reproductive nodes had moderate values of 36.9%, 35.5% and 37.4%, respectively. Number of branches and days to flowering had the lowest variability of 11.7% and 15.3%, respectively. Number of pods per plant, days to maturity, plant height and seed size had high mean estimates of heritability coupled with high genetic advance. The genetic progress of these characters that would be obtained for one generation of selection was estimated 47.2%, 45.7%, 40.9% and 40.3%, respectively. Among the agronomic characters, plant height, number of pods per plant, seed size and days to maturity had the highest coefficient of variability associated with high heritability and genetic advance. Therefore, selection for high yielding with early maturity soybean genotypes based on plant height, number of pods per plant and seed size might be possible.

Electrostatic System

In order to separate the impurities in vegetable seeds, a tribo-aero-electrostatic separator was designed and manufactured. The data analysis of the pure Descurainia Sophia seed shows that the interaction of the voltage, distance and angle was significant on the weight of the D. Sophia at the level of 1%. To determine and compare the size of the separated seeds, a laser diffraction device with the possibility of analysing the size distribution of the particles was used. The results showed that the best purity (99.5%) with the highest percentage of the relative frequency of the D. Sophia seeds size was obtained for box 1 (the first box) with a seed size of 680 μm. By moving from box 1 towards box 4, the amount of the impurities due to the variation of the electrical properties of the materials increases, although the value of the impurities for the samples is acceptable.

Abstract In-shell peanut sales provide a consistent market for large-seeded virginia-type peanuts. In this market, maintenance of a high quality product, which includes fresh roasted peanut flavor, is a recurring challenge. A maturity-seed size-quality relationship has been established for shelled peanuts. To determine if this relationship is true for in-shell peanuts, the relationships of maturity, pod size, and seed size were investigated. In two crop years (1992 and 1993) and on four to five harvest dates, virginia-type peanuts (cv. NC 9) were harvested at Lewiston, NC and sorted into hull scrape maturity classes: black, brown, orange B, orange A, and yellow. After pods were dried, they were screened to obtain the pod size distribution. Sized pods were hand-shelled, and the seed were screened to obtain the seed size distribution from each pod size from each maturity class. Hull scrape pod maturity profiles revealed a decrease of ca. 14% in yellow/orange A and an increase of ca. 14% in brown/black over the 4- to 7-d harvest period. Overall, pod size distribution did not change over time although slight differences were noted between years. Pod size distributions within individual maturity classes were more variable. The data indicated that the Jumbo in-shell grade contained higher percentages of brown and black maturity classes than the fancy grade. Fancy grades contained 26-49% immature pods (yellow and orange A maturity classes).

Recently, interracial hybridization was used successfully in breeding common bean (Phaseolus vulgaris L.), but its use has not been adequately documented. Approximately 125 lines with medium-sized seed were selected in the first cycle, mostly from race Durango × race Mesoamerica (both from the Middle American domestication center) single- and multiple-cross populations, for disease resistance and race Durango characteristics. Fifteen of these improved lines, three race Durango control cultivars, and one control cultivar each from races Jalisco and Mesoamerica were evaluated for 3 yr (1989–1991) at three locations in Colombia. A randomized complete block design with three replications was used. Lines were developed using visual mass selection for seed yield and/or resistance to diseases in F2 and F3, followed by single plant harvests in F4 or F5 and seed increases in F6 or F7. Lines resistant to bean common mosaic virus and possessing other desirable traits were yield-tested in F7 or F8. All but two lines outyielded Alteño and Flor de Mayo, the highest yielding control cultivars from races Durango and Jalisco, respectively. Two lines also outyielded Carioca, the race Mesoamerica control cultivar. Improved lines tended to possess higher yield per day. All lines were resistant to bean common mosaic virus and most lines also carried a high level of resistance to anthracnose. Plant, seed, and maturity characteristics of most improved lines were similar to those of race Durango control cultivars. These results support the use of interracial hybridization in improving race Durango common bean.

The Relationship

In Quebec, grower income from processing peas is a function of yield and tenderometer reading. If peas are harvested early, the yield is poor, but the overall quality is superior, as indicated by lower tenderometer readings. Later harvests result in g reater yields but reduced quality (higher tenderometer readings). A better understanding of the relationship between harvest time, yield and quality is needed. In this study, the relationships between yield, tenderometer readings, size distribution and grain moisture content were examined as a function of growing degree-days (GDD) and production year for pea cultivars of different seed size categories. Yield and harvest attributes (tenderometer readings, seed size distribution and moisture content) were highly season dependent and their rates of change over the course of the harvest period also varied with the cultivar and year. Quality declined rapidly once the crop reached optimal maturity, while yield increased in a less predictable manner. Consequently, it was difficult to identify a harvest time that would consistently maximize grower returns. The highest income was generally not obtained at the optimal tenderometer readings presently used by the industry.

Number Of Stems

Five spacing experiments were carried out in 1957 and '58 with seed potatoes, var. Alpha, measuring 25-28 mm, 35-45 mm and 45-60 mm, planted at 400, 600, 800, 1000 or 1200 tubers/ha in rows 60 cm apart and harvested on 7 dates between 29 July and 16 Oct. There was a positive correlation, within experiments, between the number of stems produced per tuber at wide spacings and the surface area of the skin of the tubers, both where whole tubers and cut setts were used. There was a linear relationship between the reciprocal of the yield and the reciprocal of the seed rate where both were expressed in m2 of skin surface/are. [See Fld Crop Abstr. 12: 1525 and 13: 777.] Where the reciprocal of the yield for each sett size was averaged for all 5 experiments and plotted against the reciprocal of the seed rate, it was shown that the use of large seed depressed yields; this was considered to be due to the less regular distribution of haulms in the row where the large seed was used. Seed size had little influence on grading. Rows 60 cm apart were considered too widely spaced for maximum production.-R.B. (Abstract retrieved from CAB Abstracts by CABI’s permission)

Permeability Rate

Particle size distribution (PSD) below ground may influence the groundwater flow rate. Due to that, this study focuses on laboratory scale using local alluvial soil to remove contaminants from river water using different of soil PSD samples. In horizontal permeability modelling shows permeability was influenced by the coefficient of uniformity (Cu) of sand. However, the permeability changes was differ between well and poorly graded sand. Well graded sands Cu between 4 to 5 the permeability changes are only between 7.8 – 7.9 x10-4 m/s. Whereas poorly graded sands Cu are between 2.5 to 4 the permeability change between 6.9 – 9.0 x 10-4 m/s. Whereas poorly graded sand was shows as consistent media than well graded to remove contaminants and the permeability rate is higher than well graded sand. Poorly graded (Sand B and C) removes turbidity and iron up to 50%. Because of that poorly graded soil is preferable for RBF application.
