Sugarcane (Sacharum officinarum L.) is a sugar-producing plant and is a food commodity that is needed by the people of Indonesia. National sugar demands are increasing every year. The low productivity of sugarcane is due to the competition of weeds which can reduce sugarcane production. To achieve high productivity, it is necessary to pay attention to the varieties used because they require certain conditions in their management. The purpose of this study was to determine the effect of varieties and types of weeds on the initial growth of sugarcane. The study was conducted from September 2018 to December 2018. The study used factorial Randomized Block Design (RBD) with two factors and four replications. The first factor consists of 4 sugarcane varieties, namely: Bululawang (V1), Red HW (V2), VMC (V3) and PS 862 (V4). The second factor type of weed consists of 2 types, namely Cyperus rotundus (N1) and Amaranthus spinosus L. (N2). The results showed that (1) There was interaction between the varieties (V) and the weed types (N) in stem diameter parameters and number of tillers, the treatment V4N1 gives the best response to stem diameter 1,31 cm and 4,25 number of tillers; (2) The treatment of varieties (V) gives affects to stem diameter and number of leaves, the treatment V4 gives the best response 5,38 to number of leaves; (3) Types of thorn spinach weeds can reduce the initial growth of sugarcane.

The study aimed to determine the effect of organic planting media and the position of seed planting on the growth of Robusta coffee seedlings. The study is conducted at the Tabanan Agrotechnology Study Program, Tabanan University, which conducted from July 2019 to September 2019. The treatments are arranged in factorial in a randomized block design (RBD). Two treatments examined in this study were the doses of organic matter in the growing media (0g, 150 g, 300 g, 450 g) and seed position (prone position, upside down, tilted position). The results show that the interaction between organic planting media (soil + coffee leaf compost) and seed planting position did not significantly affect all coffee seedlings growth variables. The dose of organic compost in the growing media has a very significant effect on all growth variables except when growing and the percentage of growth. The dosing of 450 g organic matter gave the highest root fresh weight, fresh stem weight and fresh leaf weight (1.00 g, 2.97 g and 8.64 g respectively) and oven dry weight for the three variables (respectively 0.39 g, 0.55 g and 1.36 g). Seed planting position has no significant effect on all observed variables, but there is The tendency of planting position with the prone on average gives better growth compared to other positions.

A altura de plantas e o diâmetro de colmos caracterizam-se como determinantes no sucesso produtivo da pastagem pela quantidade de massa produzida. Um dos fatores que alteram esses índices são as precipitações irregulares, tornando necessária a reposição da demanda através da irrigação. O objetivo do trabalho foi avaliar o diâmetro de colmos e a altura de plantas sob diferentes condições hídricas e cortes no sorgo forrageiro, em dois anos agrícolas no estado do Rio Grande do Sul. Foram conduzidos dois experimentos nos anos agrícolas de 2015/2016 e 2016/2017 em Santa Maria (RS), e foram avaliadas as alturas de plantas e os diâmetros de colmos em seis condições hídricas (não irrigado, 25, 50, 75, 100 e 125 % da ETo), em três períodos de cortes (50, 80 e 110 dias após a semeadura) em delineamento blocos ao acaso. Foram encontradas diferenças estatisticamente significativas para a variação da altura de plantas e também do diâmetro de colmos, tanto conforme a lâmina de irrigação, quanto na sequência de cortes.   Palavras chave: pastagem irrigada, capacidade de rebrote, irrigação.     KIRCHNER, J.

HEIGHT OF PLANTS AND DIAMETER OF STEMS OF SORGHUM FORAGE IRRIGATED BY CUTS         2 ABSTRACT   Achieving high pasture yields is essential for maintaining feed levels in cattle herds. Plant height and stem diameter are determinants of pasture production success by the amount of mass produced. One of the factors that change these rates is irregular rainfall, making it necessary to replenish demand through irrigation. The objective of this work was to evaluate stem diameter and plant height under different water conditions and forage sorghum cuts in two agricultural years in the state of Rio Grande do Sul. Two experiments were conducted in the agricultural years of 2015/2016 and 2016/2017 in Santa Maria / RS, and plant heights and stem diameters were evaluated in six water conditions (non-irrigated, 25, 50, 75, 100 and 125% of ETo), in three cutting periods (50, 80 and 110 days after sowing) in a randomized block design. Statistically significant differences were found for plant height and stem diameter variation, both according to irrigation depth and cut sequence.   Keywords: irrigated pasture, regrowth capacity, irrigation.

Considering the need to reduce costs in the production of seedlings, the use of agricultural wastes becomes essential. The objective of this study was to evaluate a substrate composed of agricultural residues replacing the commercial substrate. The experiment was carried out in two phases. For the first phase, seedling production, we used a completely randomized design with six treatments and eight replications, using commercial substrate (Bioplant®) and five treatments with increasing proportions of moinha/descending proportions of rice husk (0/40; 10/30; 20/20; 30/10 and 40/0%), and fixed proportions of coconut fiber (15%) and pine bark (45%). We evaluated plant height, stem diameter, number of leaves, root and shoot dry masses, and Dickson quality index at 33 days after sowing. In the second experiment, cabbage development under field conditions, the treatments were maintained with four replications, using the randomized block design. We evaluated cycle length, compactness, head and stem diameter, number of basal external leaves, mass of fresh matter of the head, and commercial yield. We recommend a substrate composed of 40% moinha, 15% coconut fiber, and 45% pine bark in the production of cabbage seedlings, replacing the commercial substrate.

 RESUMO - O objetivo do trabalho foi avaliar o desempenho agronômico e econômico na cultura do milho verde submetida ao uso de bioestimulantes na presença e ausência de fungicida. Dessa forma, dois experimentos foram conduzidos em anos distintos, em delineamento experimental de blocos ao acaso com três repetições, em arranjo fatorial 4x2. O primeiro fator correspondeu à combinação de bioestimulantes (Ausência, MC Cream, MC Extra, MC Cream+MC Extra) e o segundo fator à presença e ausência de fungicida (piraclostrobina + epoxiconazole). Foi avaliado o peso de espigas verdes, a altura de plantas, diâmetro de colmo, teor de clorofila e severidade de doenças, além da viabilidade econômica dos tratamentos. Os Bioestimulantes, na ausência de fungicida, foram eficientes para aumentar o peso das espigas verdes, altura de plantas, e o teor de clorofila. Na presença do fungicida os bioestimulantes aumentaram o diâmetro de colmo e reduziram a severidade de doenças. Os investimentos em insumos elevaram os custos de produção, porém a rentabilidade foi compensada pelo aumento da renda bruta. Em situação de baixa disponibilidade hídrica, o bioestimulante MC Extra foi o mais viável economicamente para a cultura do milho verde.Palavras-chave: fitossanidade, produtividade, renda líquida, Zea mays L. EFFICIENCY OF BIOSTIMULANTS AND FUNGICIDE IN THE AGRONOMIC AND ECONOMIC CHARACTERS OF GREEN CORN  ABSTRACT – The objective of this work was to evaluate the agronomic and economic performance of the green corn crop, subjected to the use of biostimulants in the presence and absence of fungicide. Two experiments were conducted in different years using a randomized block design with three replications, in a 4x2 factorial arrangement. The first factor corresponded to the combination of biostimulants (Absence, MC Cream, MC Extra, MC Cream + MC Extra) and the second factor was the presence and absence of fungicide (pyraclostrobin + epoxiconazole). Green ear weight, plant height, stem diameter, chlorophyll content and severity of diseases were evaluated, as well as the economic viability of the treatments.In the absence of fungicide, biostimulants were efficient to increase the green ear weight, plant height, and chlorophyll content. In the presence of the fungicide, biostimulants increased stem diameter and reduced disease severity. Investments in inputs increased production costs, but profitability was offset by the increase in gross income. In a situation of low water availability, the biostimulant MC Extra was the most economically viable for the green maize crop.Keywords: plant health, productivity, net income, Zea mays L.

Sweet sorghum is currently an important alternative for ethanol production in sugar cane off-season. In this study was to evaluate the effects of plant arrangements and the application of atrazine and S-metolachlor on growth and productivity of sweet sorghum. An experiment was conducted in randomized block design and, arranged in split plots with four repetitions. Plots consisted of spacing (0.25 m, 0.45 m 0.45-0.45-0.90 m) and sub-plots of weed control methods - atrazine (2000 g ha-1), atrazine + S-metolachlor (2000 + 720 g ha-1), atrazine + S-metolachlor (2000 + 960 g ha-1), atrazine + S-metolachlor (2000 + 1200 g ha-1), atrazine + S-metolachlor (2000 + 1440 g ha-1). Besides that, manual hoeing control was added. The intoxication of sorghum plants and weed control was evaluated at 7, 14 e 28 days after herbicides application (DAA). Plant height, stem diameter, total fresh matter, juice mass and total soluble solids (°Brix) were evaluated at 120 days after crop emergence (DAE).  There was no interaction between the factors spacings and control method for variables total matter fresh (TMF), height (H), stem diameter (D), juice mass (JM), and Brix. Application of the mixture (atrazine + S-metolachlor) in the highest doses reduced total fresh matter and °Brix. The spacing of 0.25 m provided the highest productivity of fresh matter, juice mass and increased the °Brix. The application of mixture (atrazine + S-metolachlor) controlled 90% of the weeds at 28 days after application. The increasing in doses of S-metolachlor elevates the intoxication in sorghum plants. The mixture (atrazine + S-metolachlor) has a potential for use in weed control in sweet sorghum, but at doses below 960 g ha-1 of S-metolachlor. metolachlor.

One of the main problems faced in corn cultivation, especially in Cerrado regions, is the deficiency of micronutrients. Among the micronutrients essential for the development of plants, boron (B) stands out for participating in a series of physiological processes. Based on this, the present work aimed to evaluate the performance of corn under fertilization with different sources and doses of boron. The randomized block design in a 4x3 factorial scheme was used. Four boron doses (0, 1, 2, and 3 kg ha-1) and three nutrient sources (boric acid, borax, and ulexite), applied in topdressing, were evaluated. Plant height (cm), stem diameter (mm), first ear insertion height (m), ear length (cm), ear diameter (mm), number of rows per ear, number of grains per row, 1000-grain weight (g), and grain yield (kg ha-1) were evaluated. It was concluded that the boron sources and doses used did not influence the results of plant height, first ear insertion height, number of rows per ear, and grain yield. The three doses evaluated provided increases in stem diameter, with a dose of 2.08 kg ha-1 being the one with the highest average. The application of borax and ulexite results in higher values of ear diameter, number of grains per row, and 1000-grain weight. The dose of 1.74 kg ha-1 of boron provides the highest 1000-grain weight.
