Aims: The objective of this study was to determine the optimal fertilizing method and NPK fertilizer dosage for plant physiology and nutmeg yield. Study Design: The experimental design was a completely randomized block design (CRBD) in a 4x3 factorial arrangement with three replicates. The first factor was four NPK fertilizer doses: 1, 1.5, 2.0, and 2.5kg NPK (15:15:15)/tree/year. The second factor was the manner of fertilizer application: (1) fertilized in spot, (2) fertilized in-furrow trenches trunked and (3) fertilized in hole. Place and Duration of Study: The research was conducted in Tobelo North Halmahera (1°44'45.3"-1°44'54.4" N, 127°59'54.4"-127°59'53.2" E), North Maluku, Indonesia from January 2019 to May 2020. Methodology: The nutmeg trees used was 30 years old. The population of trees plants in the study area was 40 trees. Observation parameters on leaves are chlorophyll a, b and total, nitrate reductase activity (NRA), N, P, K, proline content, number of young and old fruits. Results: The fertilization treatment with the fertilizer application method into the crack/hole fertilizer with a dose of 2.5 kg NPK significantly produced high levels of chlorophyll a, chlorophyll b,         total chlorophyll of leaves and old fruit. The number of old fruits is positively correlated with chlorophyll a content (0.615*), chlorophyll b (0.663*), total chlorophyll (0.634*) and number of young fruits (0.748 **). The application of fertilizer hole produces plants that recover quickly from drought stress, as evidenced by the highest proline content. Conclusion: NPK fertilization using the hole method and at doses of 2.0-2.5 kg/tree/year are recommended for improving plant physiology and yield.

Treatment of maize seedlings with different concentrations of sorbitol decreased the rate of germination substantially. Root and shoot length was also reduced by sorbitol treatment, however, decrease in root length was lower than shoot length. Incubation of leaf segments from maize seedlings grown in continuous light with sorbitol decreased the fresh weight and increased the dry weight in a concentration-dependent manner. Sorbitol treatment also reduced the total chlorophylls, chlorophyll a as well as chlorophyll b; the decrease in chlorophyll 'b' being more prominent than chlorophyll 'a', however, carotenoid content was declined marginally. Supply of sorbitol decreased the protein and RNA content; however, proline content and in vivo nitrate reductase activity (NRA) were increased. The results demonstrate an inhibitory effect of sorbitol-induced stress on overall growth in maize. Amongst the biochemical parameters analysed, chlorophyll, protein and RNA contents were declined, while proline content and nitrate reductase activity were enhanced with sorbitol treatment.

 Fragrant pandan leaves can be used as a natural coloring because they contain chlorophyll obtained through the extraction process. The purposes of this study were to determine the effect of particle size and extraction time on the characteristics of natural pandanus fragrance leaf extract and determine the best treatment of particle size and extraction time to produce natural pandanus leaf extract dye. This study used a 2 factorial factorial randomized block design. The first factor is the particle size which consists of 3 levels, namely 40, 60, 80 mesh. The second factor is the extraction time which consists of 3 levels, namely 24, 36, and 48 hours. The results showed that the treatment of particle size and extraction time affected the yield, chlorophyll a, chlorophyll b, total chlorophyll, brightness (L *), redness (a *) and yellowish level (b *). The treatment of 60 mesh particle size and 36 hour extraction time are the best treatment to produce natural pandanus fragrance extract coloring with yield characteristics of 8.81% chlorophyll a level of 23.66%, chlorophyll b level of 3.92%, total chlorophyll content of 27.57%, the brightness level (L *) 21.06, the redness level (a *) 4.92, the yellowish level (b *) 6.21.

The response of active ingredient, chlorophyll a and b contents, and chlorophyll index of henna to different rates of N fertilization and drought stress was explored in a split-split-plot experiment based on a randomized complete block design with four replications in the research farm of Jiroft Branch, Islamic Azad University, Jiroft, Iran in the 2016-2017 growing season. In the current study, the main plot was assigned to drought stress at three levels (including irrigation to supply 100%, 75% or 50% of plant water requirement), the sub-plot was assigned to N fertilization at three rates (50, 100 or 150 kg ha-1 pure N), and the sub-sub-plot was assigned to ecotype at three levels (Bami, Bushehri, and Rudbari). The results showed that the effect of drought level was significant on active ingredient and chlorophyll index at the p < 0.01 level and on chlorophyll a, total chlorophyll, and chlorophyll a/b ratio at the p < 0.05 level.  But, it could not influence chlorophyll b significantly. The effect of N fertilization was significant on most studied traits at the p< 0.01 level, but its effect was significant on the chlorophyll index at the p < 0.05 level and insignificant on dye and chlorophyll b. According to the results, it seems that the application of 100 kg ha-1 N and the irrigation to supply 75% of plant water requirement can contribute to having more fresh plants with the higher active ingredient and dye contents.

Indonesia is one of the largest crude palm oil (CPO) producing countries in the world. To improve oil quality, CPO purification is carried out including bleaching earth. The process produced spent bleaching earth (SBE) and deoiled spent bleaching earth (DSBE) classified as hazardous and toxic materials waste. SBE and DSBE have the potential as an adhesive material in the manufacture of NPK fertilizers. This study aimed to compare the effects of SBE and DSBE on replacing clay minerals in terms of biochemical response. The study was arranged in randomized completly block design with three treatments and blocks. The treatment consisted of NPK fertilizer containing 10% brown clay (control), NPK fertilizer containing 5% pure clay minerals + 5% SBE, and NPK fertilizer containing 5% pure clay minerals + 5% DSBE. Data were analyzed using ANOVA and tested using LSD test at a 95% confidence level. The results showed that NPK containing DSBE was able to increase nitrate reductase activity (NRA) (41.9%), chlorophyll b content (4.7%), glycine betaine (GB) (2.5%), decreasing electrolite leakage (19%), malondialdehyde (MDA) (23%) compared NPK containing brown clay. Thus the use of NPK containing DSBE and NPK containing SBE to be able to replace NPK containing brown clay.

Abstract Mulberry (Morus sp.) plant is used to feed silkworms, and the leaves contain compounds with medicinal properties of secondary metabolites. However, the content of these compounds tends to increase under stress conditions, for instance, salt stress. This study, therefore, aimed to determine the accessions of mulberry with tolerance for salt stress. The stem cuttings of seven accessions from 5 regions, Bogor, Pati, Situbondo, Bali, and Gowa, were planted following a factorial randomized block design with 3 replications. Subsequently, the first factor using the accessions, and the second factor using NaCl solution (0.0%, 0.2%, 0.3%, and 0.4% concentrations) were performed. The variables observed were growth (leaves number, plant height, and shoots number), photosynthesis rate, total chlorophyll, and proline content. The results showed that the M6 accession exhibited tolerance under high salt stress, based on the leaves number, plant height, shoot number, photosynthesis rate, and proline content. Furthermore, an increase in salt concentration was discovered to cause a decrease in growth, photosynthesis rate, and total chlorophyll content. Also, proline accumulation stimulated by high salt stress possibly plays an important role in salinity tolerance.
