Flooding is a natural phenomenon that often occurs in the rainy season arrives with high rainfall. This phenomenon give an effect to plant growth if it occurs in agricultural areas. This research was carried out at Samarinda, Indonesia. This study uses a completely randomized design non factorial, consists of 4 lavels ie; 4 hours height level 50% flooding (J1), 8 hours height level 50% flooding (J2), 4 hours height level 100% flooding (J3), 8 hours height level 100% flooding (J4), carried out with 4 repetitions. Flooding simulation is carried out 5 times in each growth phases of tomato plants. The data analysis used Anova. If the variance is significantly different, then followed by the LSD (Least Significance Different) at 5%. The results showed that simulation of flooding with times 8 hours height level 50% flooding had a morederate negative effect on tomato plants. The flooding simulation with times 8 hours height level 100% flooding gives the highest negative effect on tomato plants and the root, due to excess water requirements so that plants cannot meet needs of the plants.

In agriculture, the development of plants resistant to 2,4-D and dicamba tends to result in increased use of these herbicides in agricultural areas and consequently increases the risk in susceptible species. The aims of the present study are to assess the effects of 2,4-D and dicamba on citrus (Citrus sinensis var. Pêra Rio), lettuce (Lactuca sativa var. Stella) and tomato (Lycopersicum esculentum var. Santa Clara) and determine the best method for spray tank decontamination after applying such herbicides. All the experiments followed a completely randomized design with five replications. To study the effects of 2,4-D and dicamba on sensitive plants, experiments were performed on the following cultivated species: citrus, lettuce and tomato. Each species was subjected to 2,4-D (D, 670 g a.i. ha-1) and dicamba (D, 560 g a.i. ha-1) applied at doses of 0 D, 1 D, 0.5 D, 0.12 D, 0.03 D, 0.007 D and 0.001 D (of commercial doses (Ds)). In another experiment, the following methods were adopted to clean tanks used to spray 2,4-D and dicamba at commercial doses: wash with water (1x), water (2x), water (3x), water + 96% alcohol (1:1), water + detergent (2.5%) or no washing. The tanks were filled with water after treatment. The young tomato plants were used as bioindicators. Regarding plant sensitivity, citrus plants exhibited low potential for suffering losses due to 2,4-D and dicamba drift. The plants tolerated a dose of 0.12 D for both herbicides. Lettuce and tomato were extremely sensitive to 2,4-D and dicamba. Lettuce tolerated 2,4-D at a dose of 0.007 D but showed phytotoxicity symptoms; the tolerated dicamba dose was 0.03 D. Only the 0.03 D dose of 2,4-D was tolerated by tomato. Although the tomato plants presented phytotoxicity symptoms, the tolerated dicamba dose was 0.007 D. For the tank cleaning experiment, the spray tank cleaning by thoroughly washing in water (2x) was the most appropriate method to clean tanks used to spray 2,4-D. Washing with water (2x, at a minimum), water + alcohol (1:1) or water + detergent was equally effective to clean tanks filled with dicamba. Therefore, the study shows that the application of 2,4-D and dicamba in areas close to young Citrus sinensis plants should be avoided given that vegetable species, such as lettuce and tomato, do not tolerate the minimum drift of these herbicides. Double washing with water would be the most economical and effective method of cleaning tanks used to house these herbicides.

ABSTRACT Competition is the best known form of direct interference of weeds on agricultural crops. However, there is relatively little information on the competition of the weed sudangrass on soybean, which has been common in agricultural areas in the southern of Rio Grande do Sul. The objective of this study was to evaluate the competition between sudangrass and soybeans using replacement series experiments. The experiment was carried out in a greenhouse in a completely randomized design with four replications. The treatments consisted of soybean and sudangrass associations. The experimental units were 8-L plastic pots, in the proportions 0: 8, 2: 6, 4: 4, 6: 2, 8: 0, corresponding to 0, 25, 50, 75 and 100% of the crop and weed respectively. Shoot, root and total dry matter and plant height were analyzed through diagrams applied to replacement series and competitive indices. Soybean showed competitive superiority in coexistence with sudangrass in relation to shoot, root and total dry matter. The intraspecific competition was more significant for the crop and inter-specific competition was more important for the weed.

The present study aimed to evaluate the leaching potential of Picloram in Ultisol columns under different rainfall amounts. For such, 30 treatments were evaluated (one soil associated with three levels of rainfall and ten depths).The experiments were arranged in a split-plot design, in a completely randomized design, with four replications. PVC columns of 10 cm in diameter and 50 cm in length were filled with these soils, moistened, and placed upright for 48 hours to drain the excess water. The herbicide was applied and rainfall simulations were carried out at specified intensities, according to the treatments, to force Picloram leaching. After 72 hours, all the columns were arranged in a horizontal position and opened lengthwise. Then, soil sampling was carried out every 5 cm of depth for subsequent herbicide extraction and quantification and analysis by high performance liquid chromatography. The remaining soil samples were placed in plastic pots, and, at the respective depths, the indicator species Cucumis sativus was sown. Twenty-one days after the emergence (DAE) of the indicator plants, evaluations were conducted to verify the symptoms of toxicity caused by Picloram in the plants. It was concluded that Picloram leaching is directly dependent on the volume of rain applied. The herbicide reached the deepest regions in the soil with the highest intensity of rain. The results obtained by bioassay were in agreement with those found by liquid chromatography.

The Wilt in tomato plants is caused by Fusarium oxysporum sp. Lycopersici. Fusarium oxysporum is soil borne which causes considerable losses. FMA as a biological agent provides an alternative opportunity to control root diseases such as fusarium. The purpose of this study was to study the treatment of FMA inoculation which is appropriate while controlling the damage of tomato plants caused by fusarium. The research design used was the experimental method in Completely Randomized Design. The results showed that the treatment of mycorrhizae inoculated one week before planting and continued with fusarium inoculation at the time of planting showed good results in inducing the resistance of tomato plants to fusarium disease. This is evidenced by root colonization in tomato plants by 53% and the average intensity of attacks by 3.14%. The mycorrhizal treatment inoculated one week before planting and followed by fusarium inoculation at planting also showed good results in increasing the growth of tomato plants compared to other treatments applied by mycorrhiza.

Abstract: This present study aimed to assess seed quality of popcorn seedlings subjected to low temperatures by examining their physiological changes, enzymes, and images. We used a completely randomized design with four replications in a factorial arrangement with four hybrids (P618, AP6002, AP8202, AP8203) and five temperatures (10, 13, 16, 19 and 25 °C). Their physiological quality was assessed through radicle protrusion, germination, dry mass of seedlings and emergence. We have assessed the images of seedlings through their hypocotyl and root lengths; and through rates of automatic force, uniformity and growth, provided by Groundeye. The isozyme expressions were determined for the catalase (CAT - IUBMB: EC 1.11.1.6), alcohol dehydrogenase (ADH - IUBMB: EC 1.1.1.1), malate dehydrogenase (MDH - IUBMB: EC: 1.1.1.37) and α-amylase (α-AMY - IUBMB: EC 3.2.1.1). Results show that low temperatures cause a negative effect on seed physiological quality in enzyme expression of CAT, ADH, MDH and α-AMY and on the performance of seedlings. These alterations compromise seed quality. Hybrids AP6002 and AP8203 should be recommended for sowing at up to 16 °C. The Groundeye software was efficient in the analysis of popcorn seedlings and in for the assessment of seed quality when submitted to low temperatures.

Studies on water balance and irrigation at agricultural areas require accurate values of reference evapotranspiration. The values obtained can help farmers to determine the water requirement of these vegetable crops so that proper irrigation can be applied according to its growth stage and weather condition. The objective of this study was to calculate water requirements for four Solanaceous vegetable crops: Tomato, Potato, Chilli and Brinjal grown in temperate conditions of Kashmir Valley. Water requirements were calculated using the FAO-56 Penman-Monteith Method. The total water requirement for tomato, potato, chilli and brinjal was found 458 mm, 286 mm, 343 mm and 410 mm respectively. The maximum water was required by all crops during the mid-season stage comprising nearly 45-60% of the total water requirement of the crop.

ABSTRACT: To facilitate seeding process of forage species, a common practice is to mix seeds with fertilizers in monocropping and intercropping or in implementing integrated livestock production systems. However, in prolonged periods of contact, the fertilizer’s salinity and acidity negatively affect the seeds’ physiological quality. Therefore, this study intends to verify the effect of ten periods (0, 3, 6, 12, 24, 36, 48, 72, 96, and 120 hours) of exposure to granular NPK fertilizer 04-30-16 on the vigor and germination of Urochloa brizantha cv. Marandu seeds. The experiment was conducted in a completely randomized design with three replication. The fertilizer and seed mixture registered a negative effect on seed moisture content, electrical conductivity, emergence, emergence speed index, and seedling and radicle length as the period of exposure to the fertilizer increased from 3 to 120 hours.
