DYNAMICS OF FABA BEAN GROWTH AND NUTRIENT UPTAKE AND THEIR CORRELATION WITH GRAIN YIELD

WOS: 000295313100010Growth parameters and nutrient uptake of faba bean with 12 different genotypes were studied at the end of four subsequent growth periods, viz, first vegetative (VI), 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 (LA!), 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 RI 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.Scientific and Technical Research Council of Turkey (TUBITAK)Turkiye Bilimsel ve Teknolojik Arastirma Kurumu (TUBITAK)The authors received financial support from the Scientific and Technical Research Council of Turkey (TUBITAK) during this study

UPTAKE OF SOME ESSENTIAL NUTRIENTS IN CHICKPEA DURING DIFFERENT GROWTH STAGES IN RELATION TO BIOMASS YIELD

WOS: 000264756200001Chickpea (Cicer arietinum L.) is specially valued for its high protein efficiency ratio. Knowledge of nutrient uptake at different growth stages is an important aspect of plant mineral nutrition for achievement of high yield. A two year field experiment was conducted at the Experimental Field of Ege University Faculty of Agriculture, Department of Field Crops, Bornova-Izmir, Turkey to determine nitrogen, phosphorus, potassium, calcium, magnesium and sodium uptake of chickpea during different growth stages: slow vegetative growth, linear vegetative growth, flowering and grain filling stages. All elements except calcium showed almost similar dynamics with biomass increase during different growth stages. Calcium showed decrease in grain filling stage compared to biomass increase. These findings can be used for fertilizer management of chickpea, organic production and as a reference for interpretation of plant tissue analysis results of chickpea.TUBITAK (The Scientific and Technical Research Council of Turkey)Turkiye Bilimsel ve Teknolojik Arastirma Kurumu (TUBITAK) [TARP-2174]This work was supported by Agriculture Forestry and Food Technologies Research Grant Committee of TUBITAK (The Scientific and Technical Research Council of Turkey) as TARP-2174 project

NUTRIENT REMOVAL, PERFORMANCE OF GROWTH AND YIELD OF FABA BEAN (VICIA FABA L.)

WOS: 000285724100058A 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, FILIZ-99, SEVIL, 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.Agriculture Forestry and Food Technologies Research Grant Committee of TUBITAK (The Scientific and Technical Research Council of Turkey)Turkiye Bilimsel ve Teknolojik Arastirma Kurumu (TUBITAK)The authors thank for the financial support of Agriculture Forestry and Food Technologies Research Grant Committee of TUBITAK (The Scientific and Technical Research Council of Turkey) for this study

Heat stress and plant development: role of sulphur metabolites and management strategies

Temperature plays a crucial role in plants development whereas a sudden rise may cause severe consequences. Heat stress impairs plant growth, photosynthesis, pollen development and reproduction. The plant photosynthetic efficiency is mainly reduced by the over production of reactive oxygen species, denaturation of heat shock proteins and alteration in many enzymes activities. Unlike drought stress, plants have developed a very few mechanisms to encounter heat stress problem. Recently, the use of nutrients such as sulphur has emerged as one of the efficient methods to enhance plant tolerance against high temperature stress. The mechanistic understanding of sulphur-based strategies could be very helpful to sustain plant development and global food supplies in future hotter climates. The present review mainly focuses on (1) high temperature induced changes in plant functions, (2) possible roles of sulphur metabolites in heat stress tolerance and (3) possibilities of using sulphur as a management strategy. Moreover, the review consolidates the future research needs that must focus on (i) heat tolerant germplasm screening; (ii) sulphur dose optimisation, application method and crop growth stages response; (iii) finding of sulphur induced heat tolerance mechanisms and (iv) the use of omic approaches to discover sulphur metabolites role in heat stress tolerance
