This study aims to determine the differences in the growth response of green curly lettuce to the differentiation treatment of LED lighting with different spectrum in indoor hydroponics. The research was conducted from October to November 2017. The experimental design used was experimental with 1 lighting factor with 5 levels, there are sunlight (P0), LED 20% blue: 80% red (P1), LED 80% blue: 20% red (P2), 50% blue LED: 50 % red (P3), and 100% white daylight (P4). Observational variables included plant height, leaf number, leaf area, leaf color, total wet weight, leaf wet weight, wet root weight and dry weight of the plant. The result of this experiment showed that LED irradiation have affect the treatment are plant height, leaf number, leaf area, chlorophyll content, fresh weight of harvest, root length, and dry weight of brackets. While those that have no significant effect are the wet weight of the roots. The results showed that between LED irradiation treatment L1, L2, L3, and L4 showed that treatment L2 with 80% blue spectrum composition: 20% red showed better growth based on: high plant, chlorophyll content, and root length. Treatment with L4 with white LED showed better growth based on the number of leaves, leaf area, fresh weight of harvest, root wet weight, and dry weight of total biomass. The results below the sunlight better than the LED irradiation treatment, because the intensity of LED far low and lack of controlled environmental conditions technology and management for growing lettuce. In all of LED treatment still looked etiolation because light intensity was not optimal yet.

The performance of agricultural tractors under field conditions results from the interaction between tire and wheel affected by displacement speed. This work was developed to assess the performance of an agricultural tractor under different seeder's tire inflation pressure (518; 483 and 414kPa) and in two different gears providing speeds of 3.0 and 6.0km h-1. The experiment was performed at Jaboticabal Campus of São Paulo State University (UNESP). The experimental design used was entirely randomized in a 2-factor factorial design (3x2) with four replications. The draft force was influenced by the gear as well as by the required power; however, tire inflation pressure in the seeder did not change these parameters. Also, fuel consumption was influenced only by the tractor gear. Energy consumption was greater as speed increased, caused by gear shifting. The displacement speed was greater for the 518kPa pressure due to a lesser slippage in the seeder under this pressure. Tractor slippage did not change.

Substrate composition and container size are considered crucial for apple rootstock grown in a plug seedling system. This study investigated the effect of substrate material’s proportion and different container volumes on the growth of apple rootstock (M-9) plants propagated by tissue culture. In substrate composition, three different ratios of peat moss (PM): vermiculite (VL): perlite (PL) at 1:1:1 (S1), 1:2:3 (S2), 3:1:2 (S3) were used. For container size, plants were grown in 1000 mL (C1), 500 mL (C2), and 300 mL (C3) containers filled by 1:1:1 mixture of PM, VL and PL. In both cases, plants were treated eleven weeks in a green house. Our results demonstrate that the plant height, number of leaves, leaf area, shoot fresh weight and root fresh weight of apple rootstock were significantly higher in substrate composition S3 compared with S1 composition. However, chlorophyll content (SPAD) and photosynthesis rate were unaffected by variation of substrate composition. Furthermore, rootstock grown in C1 container showed plant height, number of leaves, leaf area, number of nodes, root length, shoot and root’s fresh and dry weight were significantly higher than those grown in C2 and C3 volume containers. The chlorophyll content and transpiration rate were not significantly affected by the different container volumes. These results suggest that the substrate ratio 3:1:2 of PM:VL:PL and container size 1000 mL were more favorable than other treatments for initial growth and development of the tissue culture propagated apple rootstock plants.

Effects of light generated by red and blue light-emitting diodes on the photomixotrophic growth of Zantedeschia jucunda `Black Magic' plantlets in vitro and tuber formation after transplant under the same PPF and photoperiod were investigated. All five treatments had the same photosynthetic photon flux (PPF, 80 ± 5 μmol·m-2·s-1) and photoperiod (16 hours daytime/8 hours nighttime), leading to the same daily light integral. Results showed that the tubular fluorescent lamp (TFL) treatment had the highest value on chlorophyll content and dry weight accumulation than other treatments using light-emitting diodes (LEDs). In LED treatments, there were no significant differences on dry weight and growth rate but with significant differences on chlorophyll content and plant height when blue light LEDs were added. It revealed that blue light was involved in plant height and chlorophyll development control mechanism. Results also showed that minor difference in 28 days of transplant production (in vitro) among treatments does not extends after 6 months of tuber formation stage grown in greenhouse. At present, blue LEDs cost much more than that of red LEDs, results of this study suggested that using red LEDs alone and powered with AC is feasible for the commercial production of Zantedeschia plantlets in vitro.

Tujuan dari penelitian ini untuk mengetahui pengaruh cekaman NaCl terhadap pertumbuhan dan anatomi akar tanaman bayam serta mengetahui konsentrasi NaCl yang dapat menghambat pertumbuhan tanaman bayam. Penelitian ini digunakan perlakuan NaCl sebanyak 0, 200, 400, 600 dan 800 mM pada tanaman bayam (Amaranthus tricolor L.), Media tanam berupa campuran tanah dan pupuk kandang dan alkohol, safranin, aseton. Alat yang digunakan adalah med line, cawan poerslen, spektrofotometer dan mikroskop. Parameter yang diukur meliputi tinggi tanaman, jumlah daun, warna daun, panjang akar, jumlah akar, berat basah, berat kering, kadar klorofil, tebal epidermis akar, tebal korteks akar dan diameter stele akar. Data dianalisis dengan uji ANOVA dilanjutkan dengan DMRT taraf kepercayaan 95% menggunakan program SPSS 15. Hasil yang diperoleh menunjukkan penambahan NaCl menyebabkan penurunan pertumbuhan tanaman bayam meliputi tinggi tanaman, jumlah daun, kadar klorofil, rasio tajuk dibanding akar dan menurunkan diameter stele akar. Pertumbuhan tanaman menurun seiring peningkatan konsentrasi NaCl karena NaCl menyebabkan cekaman osmotik yang menghambat penyerapan air dan unsur hara yang diperlukan tanaman untuk proses metabolisme.PHYSIOLOGICAL RESPONSE AND ANATOMY OF ROOTY PLANT [ Amaranthus tricolor L.] AGAINST NaClThe study was aimed at determining the effect of NaCl stress on the growth and anatomy of spinach roots and the concentration of NaCl which can inhibit the growth of spinach plants. This study used 0, 200, 400, 600 and 800 mM NaCl treatments on spinach (Amaranthus tricolor L.), planting media in the form of a mixture of soil and manure and alcohol, safranin, acetone. Med line, poerslen cup, spectrophotometer, and microscope were used in this study. The parameters measured plant height, number of leaves, leaf color, root length, number of roots, wet weight, dry weight, chlorophyll content, root epidermis thickness, root cortex thickness, and root stele diameter. The collected data then were analyzed by ANOVA test followed by DMRT 95% confidence level using the SPSS 15 program. The results obtained showed that the addition of NaCl caused a decrease in spinach plant growth including plant height, the number of leaves, chlorophyll content, the ratio of the crown to root and decreased diameter of root stele. Plant growth decreases with increasing NaCl concentration since NaCl causes osmotic stress. This stress inhibits the absorption of water and nutrients needed by plants for metabolic processes.

Nowadays much of the chemical fertilizers used in Brazil come from imports, what creates the necessity to seek for alternative fertilizers. One possibility is organic fertilizers, including poultry litter, which presents increasing availability in various regions of the country, due to the expansion of the poultry industry. Despite its availability, there are no enough studies that show the benefits of using poultry litter on soybeans in substitution of mineral fertilizer. The present study aimed to evaluate the effect of different doses of poultry litter on leaf chlorophyll content, nodulation, and development of soybean plants. It was used a completely randomized design with five doses of poultry litter (0, 1, 2, 4 and 8 t ha-1) and a control with mineral fertilizer with four repetitions. On stages R1 and R5, chlorophyll readings were done using a portable meter and also the measurement of plant height. Plants were cut near the surface, roots were washed and the nodules were detached and counted. After that, it was determined the dry weight of plant roots, nodules, and shoots. Soybean fertilization with poultry litter increases the chlorophyll content of leaves, plant height, shoot dry matter, root dry matter, and nodulation. The use of poultry litter on soybean favors its growth with decreasing increments, except for root dry matter, and with an optimum dose for each variable. The supply of poultry litter can replace mineral fertilizers in terms of soybean growth.
