<table border="1" cellspacing="0" cellpadding="0"><tbody><tr><td valign="top" width="456">Citronella grass (Cymbopogon nardus var genuinus L) is an essential oil-producing plant known as "Citronella Oil of Java". Oil is resulted from leaf distillation. The fertilization of N, P, K and Mg was expected to enhance herb productivity and oil yield of citronella grass. The research was conducted at Cicurug Experimental Garden, Sukabumi from August 2016 - February 2017. The objective of this research was to determine the proper dosage of NPKMg fertilizer on citronella grass in Latosol soil type. The study was arranged in a Randomized Block Design with 6 fertilization treatments and 4 replications. Fertilizer treatments were (1) without fertilizer (control), (2) NPKMg (12:12:17:2): (2) at the dosage of 141 kg.ha-1,(3) 281 kg.ha-1, (4) 421 kg.ha-1, (5) 526 kg.ha-1, and (6) Urea 150 kg.ha-1, SP-36 50 kg.ha-1 and KCl 125 kg.ha-1 (as comparison). The NPKMg fertilization on citronella grass enhanced plant growth and increased the productivity of biomass and oil yield. The application of NPKMg fertilization (12:12:17:2) 141 kg.ha-1 produced 23 tons of herbs, increased by 30.8 % compared to NPK fertilization without Mg. The dosage of NPKMg fertilizer (12-12-17-2) at 281 kg.ha-1 indicated the best growth and the highest herb production (24 ton.ha-1), increased by 39 %, while the highest oil content (1.4 %) was shown by 421 kg.ha-1 NPKMg (12-12-17-2) treatment, although the oil yield was insignificant compared to 281 kg.ha-1. Thus, the dosage of 281 kg.ha-1 NPKMg (12:12:17:2) can be recommended for citronella <ins cite="mailto:ASUS" datetime="2019-06-17T09:10"> grass</ins> cultivated at Latosol<ins cite="mailto:ASUS" datetime="2019-06-17T09:10"> soil type</ins></td></tr></tbody></table>

The objectives of the study were to examine the effect of NPK fertilizer and its composition on growth and yield of cashew. Treatments examined were: (1) composition of NPK (1:1:1, and 1:1:2); and (2) fertilizer dosage (500, 750, 1000 and 1500 g NPK/tree/year). The treatments were arranged in a randomized block design with 4 replications and plot size of 4 plants. Research results showed that the application of fertilizers significantly affected the growth and yield of cashew. The content of N, P and K in cashew leaves improved as the fertilizer dosage increased. Appropriate amounts of NPK were 500, 750 and 1000 g NPK/tree/year with composition of 1:1:2 for cashew trees of 5, 6 and 7 years old, respectively. The fertilizers were applied twice a year (50% in the beginning of rainy season, and 50% in the end of rainy season).

Gribaldi et al, 2018. Effort in Increasing the Growth and Production of Gambas through Adjusting the Planting Distance and Weeding Time on Dry Land. JLSO 7(2): Luffa acutangula (angled loofah) provide great benefits so that it is popular and consumed by the public. The increasing of L. acutangula production continues to be carried out in line with increasing market demand, one of them is through the improvement of cultivation techniques, such as fertilizer application, spacing and time for weeding. This study aimed to determine the increase in growth and production of L. acutangula plants at various planting distances and weeding time. This study used a randomized block design which was arranged through factorial with three replications. The factors studied consisted of: plant spacing (J), spacing of 40 cm x 50 cm (J1), spacing of 60 cm x 50 cm (J2), and spacing of 80 cm x 50 cm (J3). Weed weeding treatment (P) consists of: No weeding (P0), weeding at 15 DAS (days after sowing) (P1), weeding at 25 DAS (P2), weeding at 35 DAS (P3), and weed-free (P4). The results showed that the treatment of plant spacing and weeding time affected the plant growth and production. Spacing at 40 cm x 50 cm resulted in the best of plant growth and yield, and weeding at 35 DAS and weed-free plant produced the best growth and yield.

Total Flavonoids Content

The objective of this work was to assess the effect of different periods of water stress before harvest of pepper-rosmarin (Lippia sidoides) on the contents of essential oil and flavonoids. The experiment was carried out during 270 days of cultivation, with drainage lysimeters, in a completely randomized block design with five treatments: 0, 2, 4, 6, and 8 days of water suppression before harvest, with four replicates. Fresh and dry matter yield, essential oil content, total flavonoids content, and water potential and temperature of leaves were determined. There was a decrease of approximately 50% in oil content and of 60% in total flavonoid content with the reduction of leaf water potential in 0.3 MPa. Essential oil is more sensitive to water stress than total flavonoids.
