The boron (B) fertilization in soybean is important to ensure great yields. Boron correction must be applied in deficient soils repairing losses, exports and leaching. The objective of this study was to evaluate the effects of doses, methods and times of application of B in soybean B content and yield. The field experiments were conducted during the 2015/16 and 2016/17 cropping seasons and set as a randomized block design with nine treatments (0, 0.5, 1, 1.5, 2 kg ha-1 of B, 0.5 kg ha-1 of B mixed with NPK (02-28-18) in furrow during sowing, foliar application with 0.3 kg ha-1 of B in V4 soybean stage, foliar application with 0.3 kg ha-1 of B in R1 soybean stage, and foliar application of 0.15 kg ha-1 in V4 plus 0.15 kg ha-1 of B in R1 soybean stage) and four replications. Boric acid was the B source and the variables analyzed were: B leaf content, B exported in seeds, number of pods per plant, number of seeds per pod, weight of 100 seeds (g) and productivity (kg ha-1). The levels of B in leaf were between 30.1 and 43.8 mg kg-1 and between 65.0 and 92.6 mg kg-1 in the 2015/16 and 2016/17 growing season, respectively. Exports of B in seeds were estimated between 166 and 248 g ha-1 and between 208.9 to 260.8 g ha-1 in the 2015/16 and 2016/17 growing season, respectively. Great productivity (3,820 kg ha-1) was observed in the 2016/17 growing season, with an estimated dose of 0.95 kg ha-1 of B.

New Formulation

The use of ACCase-inhibiting herbicides without the correct addition of an adjuvant is a major cause of inefficient poaceous weed control. As such, this study aimed to assess the efficiency of a new clethodim/adjuvant formulated mixture in postemergence weed control for soybean crops. Two field experiments were conducted in the 2015/16 and 2016/17 growing seasons. A randomized block design, consisting of ten treatments with four repetitions, was used. The treatments and doses were: clethodim (108 g a.i. ha-1) + Lanzar® (0.5%), clethodim (108 g a.i. ha-1) + Nimbus® (0.5%), clethodim/adjuvant formulation at doses of (84 g a.i. ha-1), (96 g a.i. ha-1), (108 g a.i. ha-1), (120 g a.i. ha-1), (132 g a.i. ha-1), and (144 g a.i. ha-1), and a control with and without weeding. The formulated clethodim/adjuvant mixture showed high control at 7 days after application (DAA) in the 2015/16 growing season. At 28 DAA, formulation doses of 108 g a.i. ha-1 and higher exhibited superior weed control and the highest crop yields. Therefore, the use of correct adjuvant or formulated mixture is essential to increase the efficiency of clethodim herbicide.

The objective of this study was to estimate simple and partial coefficients of correlation, as well as to divide their effects into direct and indirect using path analysis for custard apple tree traits. Twenty half-sibling progenies were evaluated in a randomized block design with five replicates, and plots consisting of four plants. Six traits were evaluated in the first cropping season (mean number of seeds per fruit and mean weight of the pericarp, pulp, pedicel, seeds per fruit, and the whole fruit), while five traits were evaluated in the first three cropping seasons (mean fruit length and width, total number of fruits ha-1, mean fruit weight (in both types of analyses), and fruit yield in kg ha-1). The results of this work led to the conclusion that doing selection based on simple correlation estimates may not be convenient, since not always a cause and effect relationship can be verified between two traits. Positive correlations were obtained between number of seeds and seed weight, and between number of fruits and yield. The greatest direct effects were those obtained for pulp weight on fruit weight and for mean number and weight of fruits on fruit yield. The most important indirect effects were obtained for number of seeds and pericarp weight, obtained via pulp weight, on fruit weight, and for fruit length and width, obtained via mean fruit weight, on fruit yield.

<p class="1Body">Two field experiments were conducted from 2012 to 2013 cropping seasons to evaluate the efficacy and also determine the optimum rates of application for fish pond waste water in comparison with three other manures including one inorganic fertilizer and two organic manures under garden egg (<em>Solanum spp.</em>) crop.Garden egg was fertilized with pond waste water (PW), poultry manure (PM), pig manure (PG) and NPK15:15:15 at equivalent nitrogen (N) rates (0, 150, 300, 450 kg/ha). The treatments were arranged in a split plot under randomized complete block design (RCBD).The results obtained indicated a slight drop in soil pH but soil OM, total N, available P, exchangeable Ca and K increased generally with increasing rates of manures. The PW and PG treatments supported significantly (P&lt;0.05) the highest yields of the crop compared to PM and NPK with the 150 and 300 kg/ha treatments recording the highest increase. These results have shown that under the high rainfall and acidic soil conditions of Akwa Ibom State in Nigeria, PW is useful for the improvement of soil conditions and achievement of higher crop yields when applied at rates that supply N in the range of 150 – 300 kg/ha.</p>

ABSTRACT Knowledge about associations between traits is fundamental for plant breeding, since indirect selection can accelerate the development of promising genotypes. This study assessed the magnitude of associations between agronomically important traits in fisális (Physalis peruviana L). The experiment was conducted in Lages, Santa Catarina, and the treatments consisted of six fisális populations. The experiment was arranged in a randomized block design, with two replications and seven plants per plot. The correlations between traits were estimated based on the Pearson correlation coefficients and partitioned into direct and indirect effects through path analysis. Fruit weight was positively correlated with number of seeds (0.874), equatorial fruit diameter (0.738) and polar fruit diameter (0.672). By path analysis, number of seeds was identified as the trait with the highest direct contribution to fruit weight. The high phenotypic correlations between the equatorial and polar fruit diameters with fruit weight were mainly due to the indirect effect via number of seeds (0.505 and 0.459). The selection for heavier fisális fruits was strongly influenced by number of seeds, i.e., this trait should be taken into account for selection.

The effect of molybdenum (Mo) on common bean grown in desiccated corn stover in a no-tillage system was evaluated under two application modes: Mo mixed with the desiccant glyphosate and Mo direct spray to the bean leaves. The treatments (four replicates) were assigned to a completely randomized block design in a split-plot arrangement with the application of Mo (0, 100, 200, 400 and 800 g ha-1) mixed with glyphosate in the main plots and Mo foliar spray (0 and 100 g ha-1) in the sub-plots. The field experiments were carried out in 2009 and 2010 in the municipality of Coimbra, Minas Gerais State, with the common bean cultivar Ouro Vermelho. Mo mixed with glyphosate had neither an effect on common bean yield nor on the Mo and N contents in leaves, however it increased the Mo and N contents in seeds. Application of Mo via foliar spray increased Mo content in leaves and Mo and N contents in seeds. The reapplication of molybdenum with glyphosate for desiccation in subsequent crops caused a cumulative effect of Mo content in bean seeds.

The research was carried out in Dolog Masagal Subdistrict, Simalungun Regency, altitude ± 1.100 m above sea level. The research was conducted from January to May 2019. The purpose of this study was to determine the tolerance level of several hybrid corn varieties to cob rot disease. Methods for conducting the research used randomized block design (RBD) with 1 factor. Types of hybrid corn varieties tested were: Pioneer 29 (V1), NK 99 (V2), Pioneer 12 (V3), NK 22 (V4), Pioneer 4 (V5), Nusantara I (V6), Asia 1 (V7).The parameters observed were: plant height, cob diameter, cob length containing seeds, number of seed rows per cob, number of seeds per row, number of seeds per cob,  husk cover in cob, cob rot intensity, the amount of dry production per plot, and the weight of 1.000 seeds. Based on the research results, different types of hybrid corn varieties produce different tolerances of cob rot resistance in the Simalungun highlands. The most tolerant variety of cob rot disease is Pioneer 29 (mild damage scale = 0 - 10%). Different types of varieties planted also affect various components of growth and production, among others: plant height, number of seeds per row, number of seed rows per cob, husk cover on cob, dry production per plot, and weight of 100 grains. As for the parameters of cob diameter, cob length containing seeds and the number of seed rows per cob, the difference in varieties did not significantly affect.
