Npk Uptake

The study’s objective was to determine the effect of the NO3-: NH4+ratio and types of support on NPK uptake and pepper plant growth in field conditions. The study used a completely randomized block design with three replications. The first factor was the type of support, being the deadwood and living supports in the form of Gliricidia sp. and Ceiba pentandra. The second factor was the ratio of N fertilizer forms, which were 100% NO3-, 100% NH4+, 50% NO3-:50% NH4+, 75% NO3-:25% NH4+ and 25% NO3-:75% NH4+. The results have demonstrated that the uptake of N, P, and K, as well as the plant growth, were not affected by the interaction of the N fertilizer form ratio with the types of support. In field conditions, the black pepper prefers the N fertilizer in the form of 50% NO3-:50% NH4+. The pepper plants that were given N fertilizer in a combination of 50% NO3-:50% NH4+ have demonstrated an N, P, and K uptake, and morphology and plant dry weight were higher than the ratio of other forms of N fertilizers.

Cowpea (Vigna unguiculata L. Walp) is one of the potential substitutes of soybean due to its similar nutritional content. This study aims to determine the optimum rate of N fertilizer for the production of cowpea, and to determine the effects of the interaction between N fertilizer rates and goat manure application on cowpea production. The experiment was organized in a split-plot with a complete randomized block design with three replications. The main plot was goat manure, i.e. 0 and 5 tons.ha-1; the sub-plot was nitrogen fertilizer with five rates (0, 50, 100, 150, and 200% of the recommended rate), i.e. 0, 22.5, 45, 67.5, and 90 kg N.ha-1. Application of N fertilizer reduced the 100-seed weight and slightly reduced cowpea yield and yield components. Application of goat manure increased seed dry weight per plant, number of pods per plant, dry pod weight per plant, seed dry weight per m2, productivity, 100-seed weight, and the harvest index. There was no significant interaction between goat manure and different rates of nitrogen in affecting cowpea growth.

The Fall armyworm worm (FAW) (Spodopterafrugiperda) is one of the important economic pests which goes on several field crops and causes serious damage. The aim of this study was to look for efficient, less cost and environmentally friend plant extract for controlling Fall armyworm worm in cereal crops. A Complete Randomized Block Design (CRBD) experiments with three replications were conducted in the laboratory to investigate the insecticidal effects of four plant extracts consisting of ethanolic extract of Neem (Azadirachta indica) seeds, Black pepper (Piper nigrum) seeds, Usher (Calotropis procera ) leaves and water extracts of Argel (Solenostemma argel) leaves on larvae of the Fall armyworm (FAW) (Spodoptera frugiperda). Newly emerged larvae of FAW were treated topically by 4 concentrations (10, 25, 50 and 75%) of each extract, and then the larval mortalities were calculated after 24, 48 and72 hrs. The results showed the highest concentrations (75%) of the three ethanolic extracts gave higher mortality percentages (100%) after 72 hrs of exposure, compared with other concentrations. Also, these were not significantly different from the recommended dose of the standard pesticide “Spinosad”. On the other hand, Argel water extract showed no effect on the (FAW) larvae. It is recommended that this experiment to be replicated under different environments.

ABSTRACT Co-inoculation consists of using microorganism combinations with synergic effect that surpass the results obtained with their use alone. The objective of this work was to evaluate the effect of inoculation and co-inoculation on soybean plants, and their residual effect on maize plants grown intercropped with ruzigrass (Urochloa ruziziensis), under different N fertilizer rates. The experiment was conducted at the experimental area of the Mato Grosso State University, Alta Floresta campus, in a Typic Hapludox. A randomized block design was used for the soybean crops; the treatments consisted of Bradyrhizobium japonicum inoculated single, or co-inoculated with Azospirillum brasilense, with 20 replications. A randomized block design in a strip-plot arrangement was used for the winter maize-ruzigrass intercrop (WMRI); the treatments consisted of combination of residual effect of inoculation and co-inoculation in the strips, and five N fertilizer rates (0, 50, 100, 150, and 200 kg ha-1) in plots with WMRI, with four replications. The co-inoculation of soybean seeds and its residual effect on the maize crops increased the root dry weight of plants of both crops; however, no increases were found for most vegetative and reproductive characteristics of maize plants. Yield and most characteristics evaluated had increasing linear responses to increases in N rates, indicating the plants could respond to rates above 200 kg ha-1.

Abstract. Issukindarsyah, Sulistyaningsih E, Indradewa D, Putra ETS. 2020. The growth of three varieties of black pepper (Piper nigrum) under different light intensities related to indigenous hormones role. Biodiversitas 21: 1778-1785. Low light intensity causes the alteration of plant biochemical and morphological as the mechanism of adaptation. The experiment used split-plot design with three replications. The main plots were three light intensity levels, i.e. 100%, 75%, and 50% radiation; while subplots were three varieties namely Nyelungkup, Petaling 1 and Petaling 2. This research was conducted to figure out the effect of shadings on hormones and the growth of three varieties of black pepper (Piper nigrum L.). The results showed that in initial vegetative growth, varieties of Nyelungkup and Petaling 1 had higher growth of both ortotroph and plagiotroph branches, leaf number, leaf area, length of root, root surface area, plant dry weight, nett assimilation rate, and plant growth rate than the variety of Petaling 2. The light intensity of 50% and 75% increased the auxin and gibberellin contents of the leaf but they did not affect the zeatin. The maximum gibberellin and auxin contents of leaf were recorded at 75% light intensity. The 50% and 75% light intensity raised the length, diameter, and internode of ortotroph branch; number, length, and internode of plagiotroph branch; leaf number; leaf area; leaf area ratio; length of root; root surface area; plant growth rate and plant dry weight related to indigenous hormones role.
