<p>Os consórcios feitos de forma adequada podem resultar em inúmeros benefícios ao agroecossistema e ao produtor. O objetivo foi avaliar aspectos fitotécnicos do rabanete e alface cultivados em consórcio no oeste goiano. Foram testados 4 consórcios (com 8 plantas de alface e 20, 40, 60 e 80 plantas de rabanete, respectivamente, C I, C II, C III e C IV) em relação ao monocultivo de alface (16 plantas) e de rabanete (80 plantas) por metro quadrado. O delineamento foi em blocos casualizados, com quatro repetições. Avaliou o diâmetro, comprimento e massa média das raízes do rabanete; o diâmetro médio do coleto, número de folhas e massa média da parte aérea das plantas de alface e a produtividade de ambas as culturas. Calculou-se o índice de equivalência de área (IEA). O consórcio não afetou o tamanho e peso médio das raízes do rabanete, entretanto, a produtividade do C I (0,46 kg.m<sup>-2</sup>) foi inferior ao C III (1,97 kg.m<sup>-2</sup>), C IV (2,25 kg.m<sup>-2</sup>) e ao monocultivo (2,05 kg.m<sup>-2</sup>). Para a cultura da alface, houve diferença estatística apenas na produtividade, que foi maior no sistema em monocultivo (2,84 kg.m<sup>-2</sup>). Somente o consórcio II (0,82) apresentou IEA inferior ao monocultivo (1,0). Os consórcios apresentam potencial de uso pelos horticultores da região.</p><p align="center"><strong><em>Agronomic performance of intercropping between radish and lettuce in West goiano</em></strong></p><p><strong>Abstract</strong><strong>: </strong>Intercropping properly executed can result in many benefits to the agroecosystem and the farmer. The aim was to evaluate phytotechnical aspects of radish and lettuce intercropped in West Goiás. Four intercropping systems (with 8 lettuce plants and 20, 40, 60 and 80 radish plants, respectively, C I, C II, C III and C IV) were compared to the lettuce monoculture (16 plants) and radish (80 plants) by square meter. The design was a randomized block design with four replications. The diameter, length and average mass of radish roots; the average stem diameter, number of leaves and average mass of the aerial part of lettuce plants and the productivity of both cultures were evaluated. We calculated the land equivalent ratio (IEA). The consortium did not affect the size and average weight of radish roots, however, the C I productivity (0.46 kg.m<sup>-2</sup>) was lower than C III (1.97 kg.m<sup>-2</sup>), C IV (2.25 kg.m<sup>-2</sup>) and monoculture (2.05 kg.m<sup>-2</sup>). To lettuce crop, there was statistical difference only in productivity, which was higher in the system in monoculture (2.84 kg.m<sup>-2</sup>). Only the consortium II (0.82) had less IEA than the monoculture (1.0). The consortiums have a potential use by horticulturists in this region.</p>

The aim of this study was to obtain information for the genetic improvement of kale through repeatability and phenotypic stabilization studies and to compare methodologies that represent the reliability of the estimated parameters. Thirty-three half-sib progenies were evaluated in a randomized block design with three replicates and six plants per plot. Eight harvests were evaluated in terms of the yield of fresh leaves, number of shoots, number of leaves and average mass of leaves. Then, a phenotypic repeatability and stabilization study was performed, estimating the genetic parameters σ2a, σ²g, σ²e, and the coefficient of environmental variation and repeatability using the frequentist and Bayesian methodologies. To evaluate the reliability of these estimates, intervals were obtained using the frequentist, Bayesian and bootstrap methods. It was verified that the reliable selection of progenies of half-sib of kale can be achieved in four harvests that were realized between 95 and 170 days after planting. It was observed that the frequentist and Bayesian methodologies are better suited to obtain reliable estimates of the genetic parameters evaluated, as the last one provided smaller amplitudes for the obtained intervals. The bootstrap methodologies are not recommended for phenotypic repeatability and stabilization studies in kale.

Field experiments were conducted to assess the effect of time of introduction of maize and cropping pattern on two varieties of soybean in a soybean/maize intercrop in 2007 and 2008 seasons at the University of Agriculture Makurdi. Three periods of introduction of maize were evaluated: (i) planting at the same time with soybean;(ii) introduction of maize two weeks after planting soybean and (iii) introduction of maize four weeks after planting soybean. There were five cropping patterns viz: (i) soybean variety Samsoy-2 planted sole (ii) soybean variety TGX 1448-2E planted sole (iii) maize variety DMR-ESR-Y planted sole (iv) Samsoy -2 intercrop with maize and (v) TGX1448-2E intercrop with maize. The experiment was a split plot laid on complete randomized block design replicated three times. Results obtained revealed that there was no significant effect of time of introduction of maize on any soybean parameter observed. Yield and yield components of soybean indicated significant effect of cropping pattern (P<0.01) with number of pods per plant and grain yield. Grain yield and number of pods per plant decreased in intercrop with soybean variety Samsoy-2 having the highest number of pods per plant and grain yield. The result on maize indicated that maize planted sole was significantly (P<0.01) taller than intercropped maize, there was significant (P<0.01) effect of time of introduction of maize and cropping pattern on maize plant height, ear length, ear diameter, survival and barrenness percentage and grain yield. The Land Equivalent ratio (LER) values indicated that higher yield advantages were obtained from maize introduced two weeks after planting soybean and maize intercropped with soybean variety Samsoy-2 (1.35) than with soybean variety TGX1448-2E (1.12).

Background: Potato seed production with aeroponic technology can produce a large number of seeds, besides that it is also healthy because it uses plant seeds from tissue culture. However, how the quality of aeroponic seeds produced to become the next seed (growth capacity) has not been studied and scientifically informed. This research aimed to obtain the effect of aeroponic seed yields from the low and high plains based on their size on the growth and yield into advanced seeds. Potato seeds used were from the highland and lowland using aeroponic technology. Methods: This research was conducted in the highland (1000 m above sea level) from April to July 2017. Seeds were classified as S ≤ 1 mg, 1 ≤ Md ≤ 10 g and L ≥ 10 g. This research used a randomized block design with seven repetitions. The tried factors were as follows: 1. The origin of aeroponic seeds (A): A1 (lowland), A2 (highland); 2. The size of aeroponic seeds (U): U1 (S), U2 (M), U3 (L). Plant growth parameters included plant height, number of leaves and number of tubers. Result: The data obtained were analyzed using Duncan’s Multiple Range Test (DMRT) at the 5% level. Seeds of aeroponic yields of various sizes that are planted using drip irrigation have the potential to become advanced seeds. The L-size aeroponic seeds from the lowland produced an average of 5.9 tubers with an average weight of 68.4 g.

ABSTRACT One of the potential alternatives to improve the use of water resources is the use of hydro retainer polymer applied to the soil. The objective of this study was to evaluate how irrigation levels and doses of hydro retainer polymer interfere in the production of ’Vanda’ lettuce. The experiment was carried out from December 2017 to January 2018 under protected environment in the Instituto Federal Goiano, Urutaí Campus, Goiás State, GO, Brazil (17º 29’ 10” S of latitude, 48º 12’ 38” W of longitude and 697 m of altitude). The work tested four irrigation levels of 50, 75, 100 and 125% of the evaporation obtained daily by the hook micrometer and five doses of hydrogel polymer (0, 50, 100, 150 and 200 g plant-1). The experimental design was a randomized block design in a scheme of split-plot and four blocks. Canopy fresh and dry mass, plant height, number of leaves and productivity were evaluated. There was 29.24% increase in the dry mass comparing the hydro retainer polymer doses of 0 and 169.28 g and an increase of 14.36% of the height of plants when compared with the irrigation levels of 50 and 125%. The use of a hydro retainer polymer provided a significant increase in all the evaluated productive variables. The irrigation levels influence the fresh mass from aerial part, plant height and productivity. The productivity increased 18.42% for the irrigation levels used and the highest estimated values were presented in the dose of 157.49 g (14.46 t ha-1) hydro retainer polymer.

ABSTRACT The objective of this study was to investigate the effect of interaction between nitrogen topdressing and different application ways (active ingredients) a.i. fluazifop-p-butyl + fomesafen in weed control and agronomic performance of common bean. The experiment was conducted during winter 2003 in Selvíria/MS. The experimental design used was a randomized block design with four replications in a factorial scheme 2x7. The first factor was composed by the absence or presence of nitrogen topdressing, while the second factor consisted of different application ways of fluazifop-p-butyl + fomesafen. The following variables were measured: leaf N content, dry matter of plants, yield components (number of pods plant-1, number of grains plant-1, the average number of grains pod-1 and mass of 100 grains), grain yield, phytotoxicity and weed control percentage. The nitrogen topdressing with 75 kg ha-1provided higher dry matter of plants, higher weed control and higher common bean yield of irrigated winter. In the absence of nitrogen topdressing in the application of urea before or together to fluazifop-p-butyl + fomesafen increased their effectiveness in controlling weeds without interference in the agronomic performance of common bean.
