ABSTRACT Weeds can interfere in the growth and development of bean plants if not properly managed, especially the wild poinsettia (Euphorbia heterophylla L.). This study aimed to evaluate the competitive ability of black bean cultivars coexisting with wild poinsettia. The experiment was conducted in a greenhouse, in a completely randomized design, with four replications. Each treatment consisted of one bean plant of the BRS Campeiro, IPR Uirapuru or SCS Predileto cultivars, living with 0, 1, 2, 3, 4 or 5 wild poinsettia plants, corresponding to populations of 0 plants m-2, 22 plants m-2, 44 plants m-2, 66 plants m-2, 88 plants m-2 and 110 plants m-2. Bean and wild poinsettia plants were assessed for stem diameter, leaf area, chlorophyll content, plant height and shoot dry mass. The bean cultivars behaved differently when cultivated with distinct wild poinsettia populations. The SCS Predileto cultivar showed a higher competitive ability against the wild poinsettia than the BRS Campeiro and IPR Uirapuru, what can be verified by the reduction of leaf area and dry mass of the weed. On average, at a density of 110 plants m-2, the wild poinsettia reduces in approximately 32 % the leaf area and 50 % the dry mass of the bean plants.

This study aimed to estimate plastochron, leaf area, and yield of Physalis peruviana seedlings grown in different environments and transplanted on different dates. The experiment was carried out in a completely randomized design, arranged in a 2 x 3 factorial scheme, namely: two cultivation environments (protected and field) and three transplanting dates (10/27/2013, 12/15/2013, and 02/11/2014). Four replicates of eight plants were used per plot, and the four central plants composed the useful area. Based on mathematical models and temperature data, plastochron was estimated for the entire crop cycle and vegetative and reproductive phases separately. Leaf area and node number were measured, and their relationship established at the end of the study. Other variables assessed were fruit number, mass, and yield per plant. Our results showed that the higher temperatures in the protected environment anticipated phenological timings. Plastochron values of 60.0 and 16.5 °C day-1 can be used during vegetative and reproductive stages, respectively. The protected environment increased vegetative growth and development, as well as yield of P. peruviana seedlings. In the Guarapuava-PR region, P. peruviana seedlings should be transplanted during the spring so that higher fruit yield and quality could be achieved.

ABSTRACT The goal of this study was to evaluate the management of volunteer castor bean with herbicide applications used in pre and post-seeding of soybean crop resistant to glyphosate. Two experiments were conducted in a greenhouse in a completely randomized design with three replications. The first experiment corresponded to applications of desiccation with treatments: glyphosate (1,080 g ha-1); glyphosate + 2,4-D (1,080 + 670 g ha-1); glyphosate + carfentrazone-ethtyl (1,080 + 20 g ha-1); glyphosate + flumioxazin (1,080 + 25 g ha-1); glyphosate + saflufenacil (1,080 + 35 g ha-1); glyphosate + chlorimuron-ethyl (1,080 + 12.5 g ha-1); diuron + paraquat (300 + 600 g ha-1); and the control without application. In the second experiment, the treatments corresponded to doses of 0, 90, 180, 360, 720, 1,440, 2,880 and 5,760 g ha-1 of glyphosate for applications in post-emergence in soybean RR. The applications took place when the castor bean plant had four to six true leaves. The evaluations done in both experiments were: control and plant height at 7, 14 and 21 days after application (DAA); and stem diameter, leaf area, root volume, dry mass of shoots and roots at 21 DAA. The treatments with diuron + paraquat and glyphosate associated with 2,4-D, carfentrazoneethyl, flumioxazin or saflufenacil are more efficient for castor bean control in desiccation in pre-seeding of soybean. Glyphosate doses from 720 g ha-1 are effective to control castor bean in post-emergence of the glyphosate-resistant soybean crop.

The Heliconias have a great potential as a cut flower and for this reason an adequate management of the crop is important. The objective of this research was the application of soil amendments (Biol and superabsorbent polymers - SAP) and the analysis on their effect in the growth of Heliconia psittacorum cv. Tropica. An experiment was established using a completely randomized design with four treatments and five repetitions: SAP (1 g plant-1), biol (20 mL plant-1) + SAP (1 g plant-1), biol (20 mL plant-1) and one control (without application). A 20 cm rhizome was planted per pot and were evaluated the height of the plant, the number of leaves, the leaf area and the number of shoots were measured. The analysis of variance did not show statistical differences (p ≤ 0.05) between treatments for the variables of the height of the plant, the leaf area and the number of shoots, but statistical differences were found for the variable number of leaves (p ≤ 0.05), and the best treatments were Biol, SAP, and Biol + SAP. With the application of the biol and SAP amendments, it was not possible to increase the plant height, the leaf area and the number of Heliconia shoots. Regarding the application of SAP to the not found significant results in Heliconia, it is expected that treatments with SAP show a better effect in the dry season.

Weeds compete with plants for water, light, nutrients and space. In sugarcane, planting pre-sprouted sugarcane seedlings (PSS) may mean a change in weed interference and management. The aim of this study was to generate information on the interference of Cyperus rotundus L. in PSS. Two experiments were carried out in a completely randomized design, one with cultivar RB985476, with seven densities of C. rotundus (0, 17, 35, 70, 140, 280 and 560 plants m-2), and the second with cultivar IACSP95-5000, with four densities of C. rotundus (0, 70, 140 and 280 plants m-2). For this weed, a 2x6 factorial design was used for the experiment with RB985476 and a 2x3 design was used for IACSP95-5000, the first factor being absence and presence of the crop, and the second factor the densities of the species. Biometric evaluations of height, diameter, number of tillers and leaves, leaf area and dry mass were carried out. The PSS had a reduction in height, number of leaves and leaf area in the main till at 60 d after planting (DAP) in RB985476. For the IACSP95-5000 cultivar, there was no reduction in the analyzed variables. The average dry mass per plant of C. rotundus decreased as the density of the species increased in the absence of PSS.

The research work examined the effect of horse dung and pig dung on the early growth of Nauclea diderrichii seedling. The experiment was carried out at the back of library of Federal College of Forestry, Ibadan. The experiment consisted of five treatments which were replicated nine times in a completely Randomized design (CRD). The following materials were used: Topsoil, Polythenepot, seeds of Nauclea diderrichii, Horse dung and pig dung, sieve, wheel barrow, venier caliper, ruler, field record book and pen. Data on the number of stem girth, height, leave production and leave area were recorded fortnightly starting from a week after transplanting. The data collected were analyzed through Analysis of Variance (ANOVA). The result revealed that 15g of horse dung + 2kg of top soil had the  highest mean number of height value of 12.49cm followed by 10kg of horse dung +2kg of topsoil,(10.15cm). While topsoil only had the least mean number of height (8.25cm). The result further showed the highest mean stem girth (0.30cm) followed by 0.27cm and produced least mean stem girth of 0.24cm in treatments T12, T1 and T5 respectively. Also, in the leaf production the result revealed that 15g of horse dung +2kg of topsoil had the highest mean number of 16.69cm followed by treatment one 12,56cm and topsoil only produce the least mean leaf production of 9.40cm. The result further showed highest mean leave area (134.50cm2 ) followed by treatment one 124.60cm2 and (T5) produced the least mean leaf area of 108.06cm2. Analysis of variance (ANOVA) for plant height, stem girth, leaf production and leaf area also indicated that the treatment applied Nauclea diderrichii seedlings showed no significant effect. Generally 15g of horse dung + 2kg of topsoil produced the best result in terms of plant height, stem girth, leaf production and leave area of Nuclea diderrichii seedlings, hence treatment two (T2) is best suitable for raising Nuclea diderrichii seedlings.
