Reduced row spacing promotes more uniform spatial distribution of plants in the field. However, the adoption of reduced row spacing only is possible with smaller plants, which may be obtained with the use of plant growth regulator. This study aimed to evaluate the agronomic performance of the first corn crop with Trinexapac-ethyl applied at the different plant development stages and grown under different row spacing, with the same plant population. The experiments were arranged in a split-plot randomized block design with four replications, with row spacing for the plots (0.45 and 0.90 m) and Trinexapac-ethyl (TE) application time to subplots (control without application, at the V3, V6, V9 and V12 phenological stages). The Trinexapacethyl application time interacted with row spacings changing the growth and yield performance of the corn crop. For 0.45 m spacing Trinexapac-ethyl application at V12 and for 0.90 m spacing application at V9 and V12 reduced plant height and ear height. Trinexapac-ethyl application at V9 for both row spacings changed the plant architecture without changing the ear length and grain yield.

Field studies were conducted during the 2013 and 2014 growing seasons in central Texas near Taylor (30.5326o N; 97.4548o W) to determine the effect of hybrid, row spacing, and plant populations on corn growth and yield.  Two corn hybrids (BH 8844 and BH 8900) were compared at 53,000, 62,000, and 71,000 plants ha-1 planted one row on a single bed or twin rows (spaced approximately 20 cm apart) on a single bed. Plant counts were taken 4 to 6 wk after planting while ear height measurements were taken approximately four wk prior to corn harvest. Crop yield was determined by harvesting all eight rows of each plot with a combine. Weights were adjusted to 12% moisture. Experimental design was a factorial arrangement using a randomized complete block design with corn hybrid (2), row spacing (2), and seeding rates (3) as factors.  Data were analyzed using PROC GLM with SAS (SAS Institute, Inc., Cary, NC) and treatment means separated by Fisher's protected least significant difference test at P = 0.05.  Plant height was not affected by plant populations or row spacing as only hybrid response was significant with BH 8900 being taller in both years. Row spacing affected ear height in one of two years with the twin row spacing having a taller ear placement in the dryer year. No differences were seen with ear placement with respect to plant populations. In the dry year, yield of BH 8844 decreased as plant populations increased; however, no differences were noted with BH 8900.  In the wet year, the inverse was seen with increased yield with higher populations with both hybrids. The twin row system increased BH 8900 yield in 2013. In 2014, with BH 8844, the single row system outyielded twin row and no differences noted with BH 8900.  The results were quite variable and this was due in part to rainfall events in the two years.  Plant and ear height was influenced by hybrid while yield response was somewhat affected by population and row spacing.  A hybrid x row width response was noted indicating that certain hybrids will respond to row spacing more than others.

Lettuce is one of the most popular vegetables from various groups, because it does not need special preparation to enjoy it immediately. Its cultivation is relatively easy and does not require special techniques, making lettuce can be grown in polybags or hydroponically. Rice washing water, which is usually not utilized, actually has the potential as liquid organic fertilizer. Besides being practical and environmentally friendly, liquid organic fertilizer can be applied easily. This study aims to determine the effect of the appropriate application time interval for giving rice washing water on the growth and yield of lettuce. This research was conducted in August-October 2020 using polybags containing soil: manure: husk (1: 1: 1). The design used was a single factor completely randomized block design (RAKL). The factor is the application time interval for giving rice washing water with 4 levels, namely: W0 = without giving rice washing water (control), W1 = once every 2 days, W2 = once every 4 days and W3 = once every 6 days with a dose of 50 ml polybag-1. The results showed that the time interval treatment with washing rice water had no significant effect on plant height, number of leaves, diameter, fresh root weight, and total fresh weight of lettuce plants. However, the treatment of giving rice washing water at an interval of 6 days (W3) once showed a better value than without treatment, the time interval for giving rice washing water once every 2 days or 4 days.

The use of soybean varieties resistant to the herbicides dicamba and 2,4-D may lead to drifts towards areas grown with non-resistant varieties. The aim of this study was to evaluate the effects of dicamba and 2,4-D underdoses applied at the phenological stages V4 and R2 of soybeans. Two experiments were conducted with dicamba or 2,4-D in a randomized block design with four replications. The 4 × 2 + 1 factorial scheme was composed of four doses (0.028, 0.28, 2.8, and 28 g ae ha−1) of dicamba or 2,4-D applied at two phenological stages (V4 and R2) + a control treatment (without herbicide application). Dicamba underdoses caused damage to soybean crop affecting its vegetative growth and yield; the injuries caused by 2,4-D were neither enough to damage crop nor affect yield components. Dicamba underdoses applied at V4 caused injuries of up to 41%, while in R2 they reached 70%. Plant height decreased by up to 61% when treated with dicamba. Soybean yield was reduced by 29 and 76% when the simulated drift occurred at V4 and R2, respectively, and at a dose of 28 g ae ha−1 of dicamba. For the tested underdoses, only 2,4-D had no effect in soybean crop yield.

Providing nutrients in quantities and at the right time is of paramount importance to obtain high yields in canola culture. The objective of this work was to evaluate the agronomic performance of the Hyola 433 hybrid, submitted to potassium fertilization during flowering, during the 2016/2017 harvest. A randomized block design with four repetitions was used, in a 2x5 factorial scheme, with two canola phenological stages (F1 and F2) and five potassium doses in coverage (0, 15, 30, 60 and 120 kg ha-1). The following phenometric variables were evaluated: emergence at the beginning of flowering (EIF), flowering duration (DFL), maturation duration (DFL) and cycle; as well as agronomic variables: number of silicas per plant (NSP), number of grains per silicas (NGS), plant height (ESP), mass of a thousand grains (MMG), productivity (PRO) and oil content. There was no interaction between application times and potassium doses for MMG, PRO and oil content. The dose of 60 kg ha-1 increased the DFL and the cycle. The maximum number of 309 silicas per plant was obtained with the dose of 120 kg ha-1 of K2O. The increase of potassium concentrations reduced calcium concentration in plant tissue. In general, potassium fertilization during flowering increases the expression of variables related to canola phenology and agronomic performance.

ABSTRACT Theoretically, isogenic hybrids should not present any differences in their genetic makeup due to recombinant DNA technology. However, these materials may behave differently in relation to adaptability and stability. This study aimed at evaluating the agronomic performance of transgenic corn and their isogenic hybrids in two locations in Mato Grosso do Sul, Brazil. Three isogenic simple hybrids and two transgenic varieties of each hybrid were evaluated. The first and second corn crop of 2013/14 were simultaneously analyzed in Dourados and Caarapó, two locations in the State of Mato Grosso do Sul, totaling four environments x season conditions that were evaluated.. A randomized complete block design with three replicates per location was used, and the treatments were arranged in a 3 × 3 factorial design (three genetically modified and three conventional hybrids), with three replicates per site. Characteristics such as plant height, ear height, male flowers, female flowers, and grain yield were evaluated. The parameters adaptability and stability were estimated using the Eberhart and Russell model. In all environments, transgenic hybrids showed higher average grain yield. Considering the environments, AG 7000, a conventional isogenic hybrid, obtained the highest average grain yield. The most stable and productive hybrids were DKB 390 VT PRO and AG 7000 YG, both transgenic. All assessed hybrids exhibited greater average plant height, ear height, and grain yield in Caarapó during the second corn crop, demonstrating that the environment at that site and time was more favorable.
