Overfertilization on leafy vegetables could accumulate high nitrate content. Exceeded recommended limit of nitrate content can cause detrimental effects on the environment and human health, such as methemoglobinemia and stomach cancer. Green coral lettuce (GCL) is a leafy vegetable commonly grown under various production systems. Production system and physiological age have affected the growth and accumulation of nitrate levels in most leafy vegetables. Therefore, this study aims to determine the effects of hydroponic and conventional production on the growth performance and nitrate concentration of GCL at different harvest ages. This research was conducted in a randomized complete block design with a factorial arrangement of treatments. A stagnant hydroponic was prepared using stock A and B complete Hoagland nutrient solutions as liquid fertilizer. A commercial biofertilizer (NPK 8: 8: 8) was applied at the rate of 100 g per plant. Plant growth performance, including plant height, number of leaves, and leaf length, was measured at 7, 14, 21, 28, 31, 34, 41, and 44 days after transplanting (DAT). The fresh weight and nitrate content were measured at 31, 34, 41, and 44 DAT. The results showed hydroponic GCL exhibited higher plant height than conventional GCL. However, both productions were not significantly affected regarding the number of leaves, leaf length, and fresh weight. At 41 and 44 DAT, the hydroponic GCL was markedly higher in nitrate content than conventional. This study found that conventional production was recommended for GCL because lower in nitrate content compared to hydroponic and fair in growth performance.

Long-term use of inorganic fertilizers on leafy vegetables can increase soil acidity, harmful to the environment and leaving bad effects on human health. Organic fertilizer application is one of the safer alternatives with many beneficial effects by supplying nutrients for plant growth, environmental-friendly and producing an optimum quality of vegetables. Different organic amendment such as vermicompost, biochar and microbial compost has different effect on plant growth performance since good bacteria could improve structure of the soil and nutrient absorption. Therefore, this study aims to evaluate the effects of organic fertilizer on the growth performance and postharvest quality. The experimental design during planting was conducted in randomized completely block design with a factorial arrangement of treatmentswhile for postharvest quality study was conducted in completely randomized design. Organic fertilizer of vermicompost (110 g/plant), biochar (100 g/plant), microbial compost (80 g/plant) and chicken manure (37.5 g/plant) were treated on Pak choy two times on day 10 and day 24 after transplant. This research revealed the plant growth including plant height, leaf number and leaf length of Pak choy in all treatments were increased as growing stage increased. However, at the end of growing stage, microbial compost and vermicompost resulted in the highest of growth characteristics. In terms of postharvest quality, microbial compost showed the highest fresh weight and premium quality. This study proved that microbial compost at 80 g/plant exhibited optimum growth performance and the best postharvest quality of Pak choy.

Caladium × hortulanum Birdsey `Candidum' tubers were forced in pots until at least one-half the visible sprouts were 2 cm above the soil surface. These prefinished plants were subjected to simulated transit durations of 2, 4, or 6 days in the dark at 12.5, 15.5, 18.5, 21.0 or 24C. Plants were then grown for 4 weeks in a greenhouse and were either fertilized weekly with 100 ml of a solution containing 500 N-218P-415K (mg·liter-1) or were not fertilized. Interactive effects between transit duration and temperature were significant for all measured growth responses. Transit temperature maintained for 2 days had little effect on subsequent growth and only moderate effects after 4 days. With transit duration of 6 days, an increase in temperature resulted in increased plant height, fresh weight, number of leaves, white coloration of leaves, and percent of plants judged marketable (finished) in 4 weeks. Holding at ≈ 18.5C was most favorable for transit durations of 4 or 6 days. Use of fertilizer during finishing improved plant growth regardless of transit conditions, but did not totally negate deleterious effects from transit conditions.

Chitosan is known as the natural plant growth biostimulant and defense elicitor involving WRKY transcription factors in response to environmental stresses. However, either plant’s growth or defense responses against stress are different among the cultivars. In the previous study, chitosan and drought treatment combination on red chili plant cv. Lado resulted in the impeded growth performance followed by the down-regulated expression level of WRKY17. Hence, this study aimed to investigate the response of red chili plant from the different cultivar towards the combination of chitosan and drought treatments. At the onset of the generative phase, plants were subjected to the drought treatment with and without 1 mg mL-1 of chitosan application. Observation of plant growth performance was carried out by measuring plant height, the number of leaves, the conversion percentage of flowers developed to fruits, and the number of harvested fruits, while the molecular parameter was indicated by the analyses of WRKY17 and WRKY53 expression levels. In line with the previous study using cv. Lado, the combination of 1 mg mL-1 of chitosan and drought treatment significantly reduced the plant productivity observed in the number of fruits, followed by the plant height and the number of leaves. However, the expression level of WRKY17 and WRKY53 experienced 10 and 22-fold higher than controls, respectively. This is different from the previous study which showed the reduction of WRKY17 expression level. According to the study, it can be implied that the combination of chitosan and drought treatments on red chili plant cv. Laba could reduce plant growth performance, but increased genetics indicator towards plant’s defense system against stress indicated by the escalation of WRKY17 and WRKY53 expression level. Furthermore, the individual chitosan application are potential to increase the productivity of red chili plant cv. Laba.

Ginger (Zingiber officinale Roscoe) is an important medicinal crop grown for its aromatic rhizome which is used as a spice, food, flavouring agent and medicine. It has been characterised for its hypoglycemic, hypotensive, antioxidant and antibiotic properties. This study was conducted to determine the impact of plant growth-promoting potential of bacterial strain Bacillus subtilis L2 on plant growth and physiological properties of ginger. The experiment was carried out in randomised block design with three replications in pot experiments. The plants were grown in greenhouse conditions for three months. The results showed that at 8 and 12 weeks after planting (WAP) bacterial inoculation increased plant height, leaf length, number of leaves per plant and leaf width. Inoculation with B. subtilis L2 significantly increased plant height by 16, 20 and 18% compared to control at 4, 8 and 12 WAP. At 8 and 12 WAP, leaf length significantly raised by B. subtilis L2 as compared to uninoculated control. B. subtilis L2 significantly increased the number of leaves per plant and leaf width by 30 and 21% respectively when comparing with non-inoculated plants at 8 WAP. The percentage increase in chlorophyll content resulted from the inoculation with B. subtilis L2 over the control was 10.5%, 15.5% and 18.4% at 4, 8 and 12 WAP respectively. It is concluded that there is a significant positive effect of inoculation with B. subtilis L2 on the growth of ginger. B. subtilis L2 strain can be used as a potential agent or bio-fertiliser for stimulation of ginger growth.

This study was aimed at assessing the growth and production of celery plants grown with various compositions of N,P and K fertilizer and compost. The study was done at the Trial Farm of Faculty of Agriculture, Djuanda University, Bogor fiom September to November 2015. A completely randomized design with two factors was used. The factors consisted of compost rate and N,P and K fertilizer rate. Compost was given in four levels, namely no compost (0% R), 26.3% gcompost/plant (50% R), 52.5 g compost/plant (100% R), and 78.7 g compost/plant (150% R). N, P and K fertilizer was given in five levels, namely no fertilizer (0% R), 4 g Urea, 0.3 g SP-36, 0.2 g KCl (25% R), 0.9 g Urea, 0.6 g SP-36, 0.4 g KCI (50% R), 1.3 g Urea, 0.8 g SP-36, 0.6 g KCl (75% R), and 1.7 g Urea, 1.1 g SP-36, 0.8 g KCl (100% R). All fertilizers were administered gradually at the time of planting and 2 weeks after planting. Three replicates were allocated into each treatment making up 60 experimental units. Results showed that celery plants given synthetic fertilizer at 100% R had higher plant height, number of leaves, number of seedlings, harvest fresh weight (g), saleable fresh weight (g), root biomass (g), and root dry weight (g) than those treated with no fertilizer (0% R). Plants treated with 150% compost had higher plant height, number of leaves, harvest fresh weight (g), saleable fresh weight (g), root length (cm), and root dry weight (g) than those treated with no fertilizer (0% R). Thus the best celery growth and production in this study was obtained on plant 150% R compost   and 100% R synthetic fertilizer nourished.Key words: celery, compost, N, P, K fertilizer, harvest flesh weight
