O presente trabalho teve como objetivo estudar e validar a aplicação de defensivos através de RPAs (Aeronave Remotamente Pilotadas), comumente denominadas de Drones. O experimento foi realizado na APTA Centro Leste no município do Ribeirão Preto, SP. Foi utilizado a: solução de herbicida glifosate 1.5 kg ha-1 (Roundup WG®) utilizando 15 L ha-1 de volume de calda. O RPA que sobrevoou a área de estudo em três diferentes altitudes, juntamente com três diferentes modelos de bicos pulverizadores em uma faixa compreendida de 50 m x 5 m, sendo que nessas faixas foram distribuídos papéis sensíveis à água, para verificar o tamanho, quantidade e distribuição de gotas que caíram sobre as plantas. Uma vez contabilizadas as informações, esperou-se que fosse possível criar diferentes modelos de aplicações, levando a uma maior eficiência e eficácia das aplicações. Além disso, evitar desperdício de defensivo, contribuindo para diminuição dos impactos ambientais e aumento da segurança no campo (menor risco de intoxicações). Os resultados permitiram identificar vantagens competitivas, com destaque para a praticidade e rapidez, além de permitir controle localizado de plantas daninhas, sem a necessidade de uso de tratores, o qual aumenta compactação do solo e requer maior investimento em equipamentos. A partir destes resultados, serão estabelecidos protocolos de utilização para diversas culturas agrícolas, tais como: Amendoim (Arachis hypogaea L.), Cana-de-açúcar (Saccharum officinarum L.), Soja (Glycine max L.), Milho (Zea mays).

Hill Plots

Soybean (Glycine max (L.) Merr.) cultivars were tested for yield at various populations in hillplots that had plants compactly clumped and in comparative hill and row plots. Results indicated that thinning to a uniform stand should be worthwhile in cases where population varies and that selection in hills for material to be grown in rows could be from 43 to 95% as effective as direct selection in row plots.Key words: Glycine max, soybean cultivars, plant density, yield, hill plots, selection

Stems And Leaves

Westag 97 has larger capacity of Cd accumulation in roots which prevents Cd from translocating into stems and leaves; conversely, AC Hime has smaller capacity of Cd accumulation in roots; more Cd is transported into stems and leaves. The different capacity of Cd in roots between Westag 97 and AC Hime causes the different Cd concentration in seeds. Meanwhile, according to the different expression levels of RSTK, ISCP, and H+-ATPase between Westag 97 and AC Hime, RSTK may be involved in transporting Cd into stems and leaves; H+-ATPase may be correlated to the capacity of Cd accumulation in roots; and Cd caused some changes of fundamental life process which leaded to the different expression patterns of ISCP between Westag 97 and AC Hime.

Phytophthora Resistance

Four Japanese soybean (Glycine max (L) Merr.) cultivars (Fujiotome (PI 360836), Misaodaizu (PI 360839), Nezumisaya (PI 360841) and Honiku 65 (PI 360837)) were evaluated for Rps alleles conferring resistance for Phytophthora megasperma (Drechs.) f. sp. glycinea (Hildeb.) Kuan & Erwin. Fujiotome contains Rps1-a and Rps5; Misaodaizu contains Rsp1-c and Rps3; and Nezumisaya contains Rps1-b and a new allele, designated Rps? (Nezumisaya). Honiku 65 is susceptible but two variants obtained from it each contain a new Rps allele designated Rps? (OX939) and Rps? (OX940).Key words: Soybean, Phytophthora resistance

O presente trabalho foi realizado com o objetivo de avaliar os teores de óleo e proteína dos grãos em cultivares de soja em função do retardamento da colheita e verificar a influência da época de semeadura sob condições de baixa latitude. No ano agrícola de 2015/16, foram realizados dois ensaios de competição de cultivares de soja em Palmas-TO, sendo o primeiro instalado em 17 de dezembro de 2015 e o segundo em 04 de janeiro de 2016. O delineamento experimental utilizado em cada época de semeadura foi de blocos casualizados com setenta tratamentos e cinco repetições. Os tratamentos foram dispostos em um esquema de parcelas subdivididas, representados por dez genótipos de soja (PRISMA, TMG 132 RR, M 8647 RR, M 8372 RR, BONUS, RAÇA, ST 820 RR, OPUS, TMG 1180 RR e M 9144 RR), nas parcelas, e por sete estádios de colheita dos grãos (R6, R7, R8, R8+7, R8+14, R8+21 e R8+28 dias), nas subparcelas. Houve efeito das épocas de plantio e dos estádios de colheita nos teores de óleo e proteína dos grãos. As cultivares apresentaram comportamentos diferenciados nas duas épocas de semeaduras, a cultivar M9144 RR obteve um crescente aumento nos teores de proteína na segunda época com retardamento da colheita dos grãos. A partir do estádio R8 de desenvolvimento, o teor de óleo nos grãos de três cultivares foi maior na primeira época de semeadura. Na segunda época, quatro cultivares mostram aumento no teor de óleo a partir de R8.Palavras-chave: Glycine Max L.; retardamento; composição química dos grãos. EPOCH AND AFTER DELAYED OF SOYBEAN HARVEST VISUALIZING OIL AND PROTEIN PRODUCTION  ABSTRACT: The present work was carried out with the objective of evaluate the oil and protein contents of the grains in soybean cultivars as a function of the harvest delay and to verify the influence of the sowing season under conditions in low latitude. In the agricultural year 2015/16, two competition trials of soybean cultivars were carried out in Palmas-TO, the first one being installed on December 17, 2015 and the second on January 4, 2016. The experimental design used at each time were randomized blocks with seventy treatments and five replications. The treatments were arranged in a scheme of subdivided plots, represented by ten soybean genotypes (PRISMA, TMG 132 RR, M 8647 RR, M 8372 RR, BONUS, RAÇA, ST 820 RR, OPUS, TMG 1180 RR e M 9144 RR, on the plots, and seven stages of grain harvest (R6, R7, R8, R8+7, R8+14, R8+21 e R8+28 dias) in the subplots. There was an effect of planting times and harvest stages on the oil and protein contents of the grains. The cultivars presented different behaviors in the two sowing seasons; the cultivar M9144 RR obtained an increasing increase in the protein content in the second season with grain harvest delay. From the R8 development stage, the oil content in the grains of three cultivars was higher in the first sowing season. In the second season, four cultivars show an increase in oil content from R8.Keywords: Glycine max L.; retardation; chemical composition of grains.

These sets of experiments were conducted at Faculty of Agriculture Sebelas Maret University and the Central Experiment Station of Agricultural Faculty, Sebelas Maret University at Jumantono, Karanganyar, Central Java. The experiments were conducted under greenhouse, laboratory and field condition for each year, while the duration of this research was for two years. The specific objectives of the experiments were: (i) to determine the changes of some morpho-physiological characteristics of water stress soybean and those of unstressed plants at different growth stages; (ii) to evaluate relationship between morpho-physiological traits associated with water stress resistance and yield of soybean. In this study consists some experiments, there are: (i) about response of some soybean cultivars to water stress in screen house and field condition; (ii) about germination response of some soybean cultivars in different concentration 0f PEG; (iii) a bout recovery survival and recovery of soybean seedlings after heat treatment. The plants were well watered before thetreatment. Based on the result of the experiments, the following conclusion could be made: (i) water stress reduced growth, yield and yield components 0 f a II soybean c ultivars used; (li) PEG induced water stress resulted in lower germination, shorter root and shoot length, and increase root-shoot ratio; (iii) the ability of plants to recovery after heat stress have low correlation with drought resistance in this experiment; (iv) the determination of root-shoot ratio in the seedling stage was shown to be suitable screening techniques used to study water stress resistance.© 200'3Jurusan Biologi FMIPA UNS SurakartaKey words: soybean (Glycine max L.), cultivars, water stress.
