Domingues, Rafael; Pereira, André Belmont; Schiebelbein, Luis Miguel; Rosa, Jadir Aparecido; Barbosa, Eduardo Augusto Agnellos; Pires, Luiz Fernando.
Climatic conditions and soil water requirement notably impinge upon agriculture in such a way as to galvanize scientists to come up with advanced research in order to assure a more sustainable production at a given site. Under protected environmental conditions water is the main factor to be controlled aiming at maximization of yield and grade of agricultural products. The productive potential of a crop is extremely conditioned by the local atmospheric conditions along with requirements for water and nutrients in the soil. The aim of the current work was to scrutinize the effect of soil water status on the ecophysiological parameters and yield components of two cultivars of beans (Phaseolus vulgaris L.) under tropical climatic conditions. The experiment...

Double purpose wheat: correlation analysis of forage yield components Ciencia e Investigación Agraria
Morant,Alicia; Merchán,Héctor; Lutz,Eugenio.
The direct and relative contribution of characters associated with forage production were evaluated in a comparative assay of wheat cultivars to contribute to an ideotype defnition when selecting double purpose material for forage and grain production. Simple correlations for all of the possible combinations among the measured variables were calculated. The correlation partition method, known as path coeffcient, was applied to determine the causes of this association and to measure the relative importance of each factor. Forage production during the vegetative period was measured for each variety at the dates in which the apex reached the double ridge state (3 - 4 in the Nerson scale). The double ridge state was considered the deadline of the vegetative...

Effect of intercropping wheat with forage legumes on wheat production and ground cover PAB
Tomm,Gilberto Omar; Foster,Robert Kerry.
The use of winter legumes in southern Brazil is hindered by the slow growth of these species during establishment exposing soil surface to erosion. Introduction of these species along with spring wheat (Triticum aestivum L.) was studied as a means of increasing ground cover during their initial establishment period, without reducing wheat grain yield. Two experiments were conducted in nearby areas, one in each year. Birdsfoot trefoil (Lotus corniculatus L.), red clover (Trifolium pratense L.) cultivar Quiñequelli, white clover (T. repens L.), and arrowleaf clover (T. vesiculosum Savi) did not reduce cereal yield in either year. Wheat yield was reduced by intercropped red clover cultivar Kenland and by subclover (T. subterraneum L.) in the first year. No...

Effect of salt stress on physiology and agronomy characterstic of barley cultivars CIGR Journal
sorkhi, farshad.
In most northwest provinces of Iran such as West Azarbaijan province, soil salinity is a growing problem, particularly in irrigated agricultural areas, and has been found to reduce barley yield, dramatically. To investigate the effect of sodium chloride on two barley (Hordeum vulgare) cultivars, four levels of salinity: 0, 4, 8 and 12 dS/m, were employed as a factorial experiment arranged in a completely randomized design with three replications in a controlled environment of the greenhouse during 2017-2018. The results indicated that increasing salinity from 0 to 12 dS/m, decreased the emergence percentage significantly. Two cultivars of Zarjoo and Valfajr responded differently to salinity, so that Zarjoo showed a significantly higher emergence rate. This...

Effects of the size of sown seed on growth and yield of common bean cultivars of different seed sizes Braz. J. Plant Physiol.
Lima,Elvis Rodrigues; Santiago,Aline Silva; Araújo,Adelson Paulo; Teixeira,Marcelo Grandi.
A field experiment was conducted to evaluate the effects of planting different sizes of seed of the same cultivar on biomass accumulation and grain yield of common bean (Phaseolus vulgaris L.) cultivars of different seed sizes. A 6 X 2 split-plot factorial design with four replicates was employed, with six bean cultivars as main plots and two seed sizes (small and large, the latter twice as heavy as the former) of the same cultivar as subplots. Eight weekly samplings of biomass were performed, and yield components were measured at maturity. Large seeds increased the leaf area index and the shoot and root biomass of bean cultivars, particularly at the beginning of the growth cycle, but they did not affect the pod biomass. Improved growth associated with the...

Establishment of drought screening protocols for rice under field conditions Acta Agron. (Palmira)
Sakai,Tomoko; Duque,Myriam Cristina; Vallejo Cabrera,Franco Alirio; Martínez,César Pompilio; Ishitani,Manabu.
Protocols were established for screening rice genotypes for tolerance to water-limited conditions under field conditions. These protocols were successfully used to select the best genotypes for further experiments. Rice genotypes responded differently when subjected to water-limited conditions. Experiments conducted under field conditions indicated that rice genotypes Curinga and CT6241 performed much better in terms of grain yield under water-limited conditions than varieties Azucena, Nerica, CICA8 and Palmar. Curinga, CT6241, CICA8 and Palmar were selected for further studies. The first two genotypes are tolerant and whereas the last two are susceptible to water stress.

Fifty years of wheat breeding in Southern Brazil: yield improvement and associated changes PAB
Rodrigues,Osmar; Lhamby,Julio César Barreneche; Didonet,Agostinho Dirceu; Marchese,José Abramo.
The objective of this study was to assess the impact of genetic breeding on grain yield, and to identify the physiological traits associated to the increment in yield and their related growth processes, for wheat cultivars grown in Southern Brazil, in the past five decades. Seven wheat cultivars released between 1940 and 1992, were compared for physiological aspects associated with grain yield. Grain yield, biological yield, biomass partitioning, harvest index and grain yield components were also determined. The number of grains per square meter was more affected by plant breeding and was better correlated with grain yield (r = 0.94, p<0.01) than with grain weight (r = -0.39ns). The higher number of grains per square meter was better correlated with the...
