Exposure of bulbs to cold, a physiological phenomenon called vernalization, and bulb size are important factors in the production of lily bulbs and flowers. This study aimed to verify the influence of vernalization of bulbs on flowering cut lily plants, as well as the impact of size and shape of harvest on the production and quality of flowers and bulbs. In turn, the way the stems of the plants used for cut-flower production are cropped is of higher importance for the production of new flower bulbs. In this sense, the experiment was conducted in Viçosa, MG, in a greenhouse in a randomized block design, in split splot scheme with three replications, in which the vernalization periods (25, 35 and 45 days at 4 ± 1 C) constituted the plots; bulb sizes (diameters of 3.2-3.8 cm; 2.5-3.2 cm 1.9- and 2.5 cm), subplots and ways to harvest (full harvest of the stem at the required length for the commercial harvest of the flower, commercial stem harvest at the commercial length, maintaining 10cm of stem in the soil; removal of the floral buds as soon as their appearance is observed and harvest at the end of the season), the sub subplots. The bulbs were planted in beds, with 15 x 20 cm spacing. It was evaluated the number of plants that flowered and the number of flowers, the length and the diameter of the floral buds, fresh and dry weights, diameter and plant height as well as number, perimeter and amount of fresh and dry bulbs. There was a decrease in the plant height with the increase of the vernalization period and a reduction of the diameter of the planted bulbs, as well as of the number and the fresh and dry weights of the produced buds. The production of flowers and buds in number, size and weight was directly proportional to the size of the planted bulbs, while the form of harvest with removal of flower buds increased the number, the perimeter and the fresh and dry weights of the buds. Bulbs with diameter between 3.2 - 3.8 cm, stored for 25 days in cold chamber enable greater production of flowers and the highest stem height, factors that favor the increase in market value.

The impact of fertilizer of N and P on the yield of sesame in north-western Ethiopia was investigated. Field experiments were conducted in 2010 and 2011. Six levels of urea and six levels of di-ammonium phosphate were applied using a factorial completely randomized block design. Application of N and P increased the plant height, the number of capsules plant−1, and the yield ha−1. The number of days to flower decreased with increasing rates of nitrogen. The number of days to maturity was largest (91 days) at a rate of 23 kg N ha−1. Applying 92 kg N ha−1 resulted in a yield of 917.8 kg ha−1 and a plant height of 104 cm. An application of 92 kg P ha−1 with 36 Kg N ha−1 gave a yield of 908 kg ha−1 and a plant height of 103.4 cm. The interaction between N and P significantly affected the number of days to flower, plant height, the number of capsules plant−1, and yield ha−1. Applying 128 kg N ha−1 and 92 kg P ha−1 gave the biggest yield (1043 kg ha−1). However, application of 41 kg N ha−1 and 46 kg P ha−1 gave the largest marginal rate of return.

The objective of this work was to evaluate the productivity and the chemical quality of hydroponic corn forage grown on different substrates. The experiment was conducted at the Federal Institute of Science and Technology of Roraima – Campus Novo Paraíso, in the municipality of Caracaraí, Roraima, Brazil. The experiment was carried out in a randomized block design, with five sowing rates (treatments) and four replications. Hybrid corn seeds 2022 were used, sown on a double-sided canvas. When germination started, fertigation with nutrient solution was carried out. The evaluation occurred on the 10th day after sowing and included determination of plant height (cm) and roughage productivity (kg m² and t ha-¹) and bromatological analyses (% N, PB, FDA, NDF and NDT). For bromatological analyses, corn plants were collected, dried in an oven at 65 ºC and then crushed. The productivity of natural forage (k m² and t ha-¹), plant height and the neutral fiber content (NDF) of hydroponic corn were higher at the sowing rate of 2.5 kg m². These variables were influenced by the sowing rate and type of substrate, but resulted in a lower crude protein content. The results show that sugarcane bagasse was a suitable substrate for hydroponic corn, which is justified by the fact that it presents fewer moisture losses, avoiding the loss of nutrients in the nutrient solution. At a sowing rate of 1.0 kg m², the forage produced had a higher content of nitrogen, crude protein and total digestible nutrients, which are important for animal nutrition.

Differences in levels of lignin in the plant between conventional and transgenic cultivars RR has been reported by several authors, however, there are few studies evaluating the influence of spraying of glyphosate on the lignin in the plant and RR soybean seeds. The aim of this study was to evaluate the physiological quality of RR transgenic soybean seeds and the lignin contents of plants sprayed with the herbicide glyphosate. The assays were conducted both in greenhouse and field in the municipality of Lavras, MG, in the agricultural year 2007/08. The experiment was arranged in a splitplot design with four replicates, considering the treatments hand weeding and herbicide glyphosate as plots, and five RR soybean cultivars (BRS 245 RR, BRS 247 RR, Valiosa RR, Silvânia RR and Baliza RR) as splitplots. In the greenhouse, the cultivars tested were BRS 245 RR and Valiosa RR in a randomized block design with four replicates. The sprayings were carried out at stages V3, V7 and early R5 (3L/ha). The 1000 seed weight, mechanical injury, germination and germination velocity index, emergence velocity index, accelerated aging, electrical conductivity and water soaking seed test, lignin content in the seed coat, in the stem and legumes were determined. The spraying of glyphosate herbicide, in greenhouse and field, did not alter the physiological quality of seeds and the lignin contents in the plant.
