Optimal ratio of spectrum, light intensity and photoperiod to minimize costs when growing microgreens
نویسندگان
چکیده
The paper considers the influence of spectrum and light intensity/photoperiod ratio on energy intensity production financial costs consumed electricity. This is caused not only by yield obtained, but also different efficiency lightemitting diodes price electricity at hours day. Considering spectrum, it was found that decrease with increasing proportion red for all microgreen varieties under consideration. Laboratory studies were carried out microgreens cabbage “Mitsuna” variety radish “Octave” variety. A long photoperiod low better than a short high in terms efficiency. Combining results dry weight as quality indicator, consumption cost per fresh weight, we consider lighting system parameters B:R:FR=29:58:13%, PPFD= 100 μmol·m -2 ·s -1 / 16 h preferred option growing microgreens.

The Optimal Dietary Threonine to Lysine Ratio for Growing Pigs
The growth of 64 pigs was monitored over grower and finisher periods of 26-58 and 58-96 kg respectively, to see if the optimum dietary ratio of threonine to lysine (T/L) under ad Zibitum feeding was higher than the generally accepted ratio of 0.6. Five basal (Bl-B5) diets were used to establish the pig’s response to lysine (in the range 6.0 to 11.24 and 5.59 to 10.5 g kg-1 for grower and finish...
متن کاملOptimal delivery time quotation in supply chains to minimize tardiness and delivery costs
There are many situations when, due to unexpected delays, the supplier may not be able to deliver some orders by the promised due dates. We present a model for quoting attainable delivery times to minimize tardiness penalties and delivery costs, when deliveries take place in batches. We show that the general problem is strongly NPhard, but when all orders have the same per-unit due-dateassignme...
متن کاملSpectrum Intensity Ratio and Thresholding Based SSVEP Detection
The feature extraction of Steady-State Visual Evoked Potential (SSVEP) is developed in a frequency domain regardless of the limitation in hardware architecture. We introduced a spectrum intensity ratio as a simple characterization and separation of SSVEP. However, it is difficult to classify an unseeing state of subjects. In this paper, we propose an adaptive threshold to reject the unseeing st...
متن کاملInteractive Effects of Vernalization, Photoperiod and Light Intensity on Reproductive Development of Wheat Cultivars
475 Abstract: The interactive effects of vernalization, photoperiod and light intensity on the length of the apex or spike and main shoot, and the diameter of the main shoot of five different wheat (Triticum aestivum L.) cultivars (Çukurova-86, Atay-85, Lancer, Haymana79 and Bezostaya-1) having different biological characters were investigated. The research was carried out in four independent e...
