Changes in conserved field conditions by growing faba bean (Vicia faba L.) during two varied meteorological years

Growth and development of twelve different faba bean genotypes were studied during two subsequent years (2005- 2006 & 2006-2007) in their growing seasons, from October - March, in the research fields of Ege University, Turkey. The study was conducted in a randomized complete block design in an organic field. Various growth parameters of faba beans, including plant height, leaf number, leaf area index (LAI), leaf dry weight, root dry weight, and total plant dry weight were measured. The plant height and leaf number differed significantly (p<0.05) across genotypes and years, and showed genotype x year interactions. Moreover, LAI also statistically varied between genotypes and years, but no genotype x year interaction was observed. The leaf dry weight, root dry weight, and total plant above ground dry weight were found to be significantly different for genotypes, years and their interactions. The variation between years was due to differences in rainfall and soil nitrogen (N) that were high in the first year compared to the second year and these were the factors responsible for changing the conservation status of the field under study. The findings indicated that on an average, a faba bean has 101.90 cm plant height, 49.95 number of leaves plant-1, 3.49 LAI, 354.83 kg leaf dry weights ha-1, 11944 kg total above ground plant dry weight ha-1, and 865 kg root dry weight ha1. These findings are based on number of genotypes and can be used as a reference for growth and development of faba beans. Furthermore, differences in N in the organic fields during the study period shows that it needs to be managed in organic farming even for legume cropping system

Dynamics of faba bean growth and nutrient uptake and their correlation with grain yield

Growth parameters and nutrient uptake of faba bean with 12 different genotypes were studied at the end of four subsequent growth periods, viz. first vegetative (V1), second vegetative (V2), first reproductive (R1) and second reproductive (R2) periods for two years and correlated with final grain yield. All parameters including plant height, leaf number, leaf area index (LAI), above ground plant dry matter (DM) and root DM, nitrogen (N), phosphorus (P), potassium (K), calcium (Ca), and magnesium (Mg) uptake and concentration of N, P, K, Ca, and Mg showed different patterns with advancement of the growth period. All the mentioned parameters were fitted in either quadratic or linear equations. Significant correlations were found among nutrients, growth parameters and grain yield during different growth stages. On the basis of these experiments it was clear that nutrient uptake was directly related to biomass. In V2 and R1 biomass production was greatest resulting in high nutrient uptake. Among the growth parameters, biomass and LAI showed the highest significant correlation with grain yield. The findings especially models derived from two year data across twelve genotypes can be used for better fertilizer management of faba bean. © Taylor & Francis Group, LLC.National Council for Scientific ResearchThe authors received financial support from the Scientific and Technical Research Council of Turkey (TÜBİTAK) during this study. -

Nutrient removal, performance of growth and yield of faba bean (Vicia faba L.)

A study on 12 faba bean genotypes was conducted for 2 years to evaluate its growth, nutrient removal, yield and yield components. The genotypes were KITIKI-2003, ERESEN-87, FİLİZ-99, SEVİL, SAKIZ, 95 ETA 225, 95 ETA 249, 95 ETA 276, 97 ETA 718, 97 ETA 727, 98 ETA 296 and 98 ETA 329. In each year mostly significant differences were observed among genotypes for growth, nutrients removal, yield and yield components. In the study on the average of two years across the 12 faba bean genotypes 301 kg ha-1 nitrogen, 30.0 kg ha-1 phosphorus, 206.9 kg ha-1 potassium, 138.5 kg ha-1 calcium and 23.9 kg ha-1 magnesium were uptaken in response to 11944 kg ha-1 plant dry matter production. In addition to the nutrient study on the average 101.9 cm plant height, 3.49 LAI, 864.4 kg ha-1 root dry matter and 11944 kg ha-1 plant dry matter were observed in the experiment. Furthermore, 7.84 pods plant-1, 2.35 grains pod-1, 1557.1 1000-grain weight and 4585 kg ha-1 grain yield were recorded. These findings can be used for fertilizer management of faba bean, sustainable faba bean production and as a reference

Relationship between some plant growth parameters and grain yield of chickpea (Cicer arietinum L.) during different growth stages

Relation between some plant growth parameters (Leaf Area Index (LAI), Net Assimilation Rate (NAR), Relative Growth Rate (RGR), Leaf Area Ratio (LAR), Leaf Area Duration (LAD) and Crop Growth Rate (CGR)) with biomass and grain yield of chickpea (Cicer arietinum L.) during four growth stages (slow vegetative growth stage, linear vegetative growth stage, flowering stage and grain filling stage) were studied in the field experiments conducted at Bornova, Izmir. There was a wide variation among genotypes for all the growth parameters during the growth stages. Highest values of LAI and LAD were recorded for the period of linear vegetative growth stage; RGR and LAR through slow vegetative growth stage; NAR and CGR during flowering stage. Significant correlations among most of the growth parameters were found during all the growth stages. Most of the growth parameters except NAR also showed significant correlation with biomass. Mean grain yield was 1.86 t ha-1 that varied between 1.41 and 2.27 t ha-1 for different varieties

Effect of different levels of nitrogen on dry matter and grain yield of faba bean (Vicia Faba L.)

Faba bean is widely used in the Mediterranean region as source of protein in both human and animal nutrition. A legume member so fixes atmospheric nitrogen but with the assumption that nitrogen application to crops often results in yield improvement, a field experiment with N rates was conducted for two consecutive years. In the experiment 12 faba bean genotypes (KITIKI-2003, ERESEN-87, FİLİZ-99, SEVİL, SAKIZ, 95 ETA 225, 95 ETA 249, 95 ETA 276, 97 ETA 718, 97 ETA 727, 98 ETA 296 and 98 ETA 329) at 5 N rates (0, 50, 100, 150, and 200 kg ha-1) were evaluated for dry matter production and grain yield. Genotypes showed significant variation in grain yield and shoot dry weight. Genotype FİL·Z-99 was the highest yielding, whereas genotype SEVİL was the lowest yielding and the remaining genotypes were intermediate in grain yielding potential. Grain yield and shoot dry weight indicated significant quadratic relation with the increasing N rates between 0 and 200 kg ha
