PENGARUH LAMA PENYINARAN LAMPU LED MERAH, BIRU, KUNING TERHADAP PERTUMBUHAN MICROGREEN KANGKUNG (Ipomoea reptant)

Microgreens are vegetables that can be harvested about 7-14 days after germinationwhich has a higher nutrient and vitamin content than commonly grown vegetables. Thisstudy aims to determine the interaction between the type of light and the duration oflighting and the effect of the types of red, blue, yellow LEDs and red, blue, yellow LEDlighting on the growth of kangkung microgreen. This research is a box experiment using aSplit Plot Experiment Design with 9 treatments and 3 replications. The results showed thatthere was an interaction between the type of lamp and the duration of lighting to thegrowth of kangkung microgreen. The combination of C3T1 treatment (Yellow LED + 6hours) produced the highest plant length, namely 6.47 cm at 7 DAS, the number of leaveswas 2.00 for all treatments. The different types of lamps in kangkung microgreen had asignificant effect on growth, where the blue LED light produced the highest number ofleaves, namely 2.00 leaves at 14 DAS. The highest fresh weight per box was 18.36 g. While the Yellow LED produced the highest plant length of 9.42 cm at 14 DAS, the highestnumber of leaves was 2.00 pieces 14 DAS, the highest root length was 7.22 cm, thehighest dry weight per box was 1.03 g. The difference in lighting time onkangkung microgreen has a significant effect on the growth, where the 6 hours lightingduration produces the highest root length, namely 7.96 cm, the highest fresh weight perbox is 23.17 g, the highest dry weight per box is 1.87 g. The length of 12 hours of lightingresulted in the highest plant length, namely 10.41 cm at 14 DAS, the highest number ofleaves was 2.00 leaf blade. Based on the results of this study it can be recommended thatthe cultivation of kangkung microgreen in the box experiment can be using lighting for 6hours and pay attention to the microelements that affect the microgreen for better growth.Keywords : Microgreen, Kangkung, Red, Blue, Yellow, LED lights

The Effect of Species and Cultivation Year on Phenolic Acids Content in Ancient Wheat

During the last decade older (ancient) wheat species, such as spelt (Triticum spelta L.), emmer (Triticum dicoccon Schrank), and einkorn (Triticum monococcum L.) have been recognised as an interesting option to increase the biodiversity of cultivated cereals. The aim of this study was to compare polyphenols content in the ancient species of cereals (including six accessions of spelt, four of emmer, and one of einkorn) cultivated in the three-year controlled plot experiment under organic management. It has been found that the content of almost all free and bound phenolic acids was significantly higher in einkorn than in emmer and spelt wheat species. Moreover, the concentrations of ferulic, p-coumaric, and caffeic acids in einkorn and emmer was higher in dry and very warm cultivation years. It is concluded that ancient wheat species, especially einkorn, could be an important source of phenolic acids in the human diet.

Effect of Nitrogen and Variety on Agronomic Performance of Rhodes Grass (Chloris gayana Kunth) in the Sudan

An experiment was conducted in Shambat (2016-2017) in the demonstration farm of the College of Agricultural Studies, Sudan University for Science and Technology, to study the effect of variety and nitrogen fertilization on the agronomic performance of Rhodes grass. Two Rhodess grass varieties (Fine cut and Reclaimer) and 2 nitrogen doses plus control were studied across seven cuts. The treatments were replicated four times in split plot experiment with fertilizer doses assigned to the main plots and the varieties to the sub-plots. The data collected included forage yield, plant height and days to 50% flowering.

Evaluation of industrial tomato genotypes in open-field production

Recently, industrial tomato production in Hungary shows an increasing tendency after a weak processing period. However, to maintain the cultivation profitable, the use of proper technology and genotype is indispensable. In the experiment, five hybrids and one variety were evaluated in a plot experiment design on open field. The main objective was to evaluate the fruit quality of different genotypes and to determine the suitability for mechanical harvest. According to the results, Heinz 1015 F1 and Heinz 9478 F1 had the best fruit quality for industrial processing. Nowadays, the use of hybrids with good adaptability and resistance properties is important for a profitable production.

The changes of the purple coneflower’s (Echinacea purpurea L.) herb and radix drug yield under different fertilization conditions

In this research, the purple coneflower’s (Echinacea purpurea L.) nutrient requirement was examined under different fertilization conditions in a small plot experiment. We measured the medicinal plant’s raw and dry herb and root drug mass and drying loss under different fertilization settings and meteorological factors. From the drug’s raw and dry mass perspective, based on the results, in our opinion, the control setting exceeded all nutrient settings’ results in 2016. In 2017 and 2018, the N75P100K150 nutrient setting has the biggest herb yield. As for the root yield, it was also the N75P100K150 setting which produced the biggest yield. The Pearson's correlation test was performed to investigate the connection between the quantity of the raw, the dried herbs, the different nutrient settings and meteorological factors.

Influence of Rhizobium, Pseudomonas and Mycorrhiza on Some Physiological Traits of Red Beans (Phaseolus vulgaris L.) under different irrigation conditions

This study was conducted to evaluate response red bean (CV. Goli) under drought stress conditions for three types of biological fertilizers in 2014 - 2015 years. A split plot experiment was conducted in Tabriz, Iran. Irrigation levels (irrigation after 70, 110, and 150 mm of evaporation from pan) were considered as main plots, and biological fertilizers Rhizobium (Rp), Mycorrhiza (My), Pseudomonas (Ps), Rp + My, Rp + Ps, Rp + My + Ps, and non-inoculation (control) were considered as sub plots. Combination of Rhizobium, Mycorrhiza, and Pseudomonas at irrigation level of more than 70 mm of evaporation had the highest grain yield, RWC, CCI, stomata conductance, leaf water potential and lowest cell leakage. Triple inoculation increased grain yield in comparison to the control, or to the time they were used individually or simultaneously; it also reduced the negative effects of drought stress on the beans.
