ABSTRACT The objective was to evaluate the effect of different spacings and mineral fertilizations on cactus pear growth and production in a randomized block design, with three replicates, in a 3 x 4 factorial scheme: three spacings, 1.00 x 0.50 m, 2.00 x 0.25 m and 3.00 x 1.00 x 0.25 m, and four fertilizations, 000-000-000, 000-150-000, 200-150-000 and 200-150-100 kg ha-1 of N, P2O5 and K2O, respectively. Plant growth was evaluated between 90 and 390 days and production and growth were evaluated at 620 days after planting. There were significant interactions between spacing and fertilization for plant height, number of cladodes and cladode area index from 90 to 390 days and for production of fresh and dry matter at 620 days after planting. Spacing influenced cladode area index, while fertilization influenced plant height, number of cladodes and cladode area index at 620 days after planting. Plant height showed cubic effect for the days after planting. Number of cladodes and cladode area index were dependent on spacing, fertilization and plant age, and fitted to cubic models. The best results of growth and production of fresh and dry matter are associated with NPK and NP fertilizations and the spacing of 1.00 x 0.50 m.

The objective of the present study was to evaluate the row hoe model CHOPSTAR®, the mechanical control of weeds in between the rows of soybean implanted in organic direct sowing system, associated with the camera-guided system. Two experiments were carried, being that in the first experiment an experimental design with sub-subdivided plots with four replicates. The plots corresponded to two soybean varieties (‘Embrapa BRS 284’ and ‘Coodetec CD 216’), the subplots corresponded to the sowing densities of 329.2 and 574.6 thousand plants ha-1; and the sub-subplots corresponded to four managements of weeds: one mechanized hoe (2 days after sowing – DAS), two mechanized hoes (22 and 47 DAS), one control manually hoed and other control without hoeing. In the second experiment a randomized block design in subdivided plots with three replicates was used. The plots corresponded to two soybean varieties (‘BRS 284’ and ‘DF 2353’), the subplots constituted of different times when the hoes were made, being: one (14 DAS); two (7 and 21 DAS; two (14 and 28 DAS); three (7, 14 and 28 DAS); besides one control manually hoed up to 28 DAS. In the first experiment it was observed that the automatized hoe was efficient in controlling the weeds and it was necessary only one mechanized hoe (22 DAS) for the ‘BRS 284’ independent of the sowing density, while for the ‘CD 216’ the number of mechanized hoes depended on the sowing density. In the second experiment, it was necessary only one mechanized hoe (14 DAS) to avoid production losses in the varieties ‘BRS 284’ and ‘DF 2353’. The automatized hoe is an alternative to control weeds in areas of organic soybean in direct sowing system, however, damages to the crop can occur depending on the sowing density, mainly in the late management of the mechanized hoe.

An investigation was carried out to study the effect of nitrogen and phosphorus on growth, flowering and yield of cut chrysanthemum cv. Thai Chen Queen. The experiment was laid out in randomized block design (RBD) with factorial concept comprising of twelve treatment combinations with four levels of nitrogen, viz., 100 kg N/ha (N1), 150 kg N/ha (N2), 200 kg N/ha (N3) and 250 kg N/ha (N4) and three levels of phosphorus, viz., 50 kg P2O5/ha (P1), 75 kg P2O5/ha (P2) and 100 kg P2O5/ha (P3). The treatments were replicated four times. The results indicated that application of 200 kg N/ha (N3) to cut chrysanthemum was most effective to increase plant height whereas, plants receiving 150 kg N/ha significantly improved vegetative growth as well as quality and yield of flowers. Application of 75 kg P2O5/ha was found promising for growth, quality as well as yield parameters.

required. Maize with cp4-epsps and pat genes is tolerant to glyphosate and glufosinate-ammonium herbicides and has been a tool used for weed control. However, there is a demand for new studies to assess how tolerant it is and to avoid yield losses. The objective of this study was to assess the selectivity of the 2B810PW hybrid, which has the cp4-epsps and pat genes, subjected to applications of glyphosate (gly) and glufosinate-ammonium (glu), both isolated and combined, at two different rates, during three crop years, in two municipalities in Paraná state. A randomized block design, with four replications, was used. Some measured variables, such as plant height, showed few differences between crop years and locations, while others, like percentage of seed germination and yield, showed no differences (P ≤ 0.05). This demonstrates that the hybrid is resistant to the application of glufosinate-ammonium and glyphosate herbicides, isolated or combined, and these molecules can provide more options for weed control in crops of maize containing the cp4-epsps and pat genes.

The objective of this study was to evaluate, through path analysis, the influence of agronomic characters as a function of foliar spraying and furrow inoculation by Azospirillum brasilense on soybean yield. Two experiments were conducted in the crop years of 2013/14 and 2014/15, grown in Lavras, Minas Gerais. In the first experiment, the experimental design was a randomized block in a factorial 4 × 6, four cultivars (Anta 82 RR®, BRS Favorita RR®, BRS 780 RR®, BRS 820 RR®) and six doses of A. brasilense (0, 300, 400, 500, 600, 700 mL ha-1), with three replications. In the second experiment, the experimental design was a randomized block design, arranged in a 4 × 2 factorial scheme, four cultivars (Anta 82 RR®, BRS Favorita RR®, BRS 780 RR®, BRS 820 RR®) and two treatments with A. brasilense (inoculated and non-inoculated) with three replications. For both experiments, it was established plant height, phytomass of the aerial part, plant height at harvest, first legume insertion, number of legumes, number of grains per legume, mass of one thousand grains and grain yield. In the study with foliar spraying of soybean with A. brasilense, plant height at harvest was the only variable that had a direct effect on soybean grain yield. As such, in the study with furrow inoculation of A. brasilense in soybean, plant height at harvest and number of vegetables were the variables with the greatest direct effects on soybean grain yield.

The Ideal

In the search for optimization of production, the use of the ideal plant density is of fundamental importance. So, the objective of this research was to evaluate the effect of planting densities on chive production, varying the spacing between holes and the number of plants per hole. The experimental design was a randomized block design, with twelve treatments in the 4 x 3 factorial scheme, with four spacings between holes (0.05, 0.08, 0.11 and 0.14 m) and three numbers of plants per hole (2, 3 and 4 plants per hole), with four replicates. Leaf number, plant height, leaf diameter, fresh and dry shoot weight (g plant-1) and yield (t ha-1) were evaluated. It was observed that with a greater number of plants per hole, there is reduction in the production per plant, however, the yield is higher. The smaller the spacing, the greater the yield of chives. So it is possible to recommend the higher plant density for chive production, and the use of three or four plants per hole.

Weed competition has been a major challenge limiting crop yield especially in intercropping systems. Information on the use of chemicals for weed control in intercropping systems appears scanty. The aim of this study was to investigate the efficacy of pendimethalin (P) at 1 kg active ingredient/ha, and hand weeding (HW) on mineral contents of the harvested grains and effects of various weed control treatments in maize, cowpea, and their intercrop. Field experiments were carried out during the 2017 and 2018 rainy seasons. The field layout followed complete randomized block design with three replicates. There were eight treatments: Sole Maize/Cowpea + P, Sole Maize/Cowpea + P + 1HW at 3 weeks after sowing (WAS), Sole Maize/Cowpea + P+ 2HW at 3 and 6 weeks after sowing (WAS), Sole Maize/Cowpea weedy check, Intercrop + P, Intercrop + P + 1HW at 3WAS, Intercrop + P + 2HW at 3 and 6 WAS and Intercrop weedy check. It was observed that, P+1HW and P+2HW in both cropping systems have significant effects (p<0.05) and effectively control weed and increase the mineral contents in maize, cowpea, and their respective intercrop. The study revealed that, the mineral composition of maize and cowpea grains were improved by using pendimethalin with supplementary hand weeding. The study recommends that farmers should adopt intercropping maize with cowpea using pendimethalin plus one supplementary hand weeding at 3 WAS.
