Abstract

Nanotechnology is a science that deals with objects measuring 1-100 nm that are different from their original properties. Nano-technology fertilizers are more reactive and on target with minimum use. Nanotechnology fertilizers can be utilized as slow-release fertilizers, allowing for optimum fertilizer uptake by plants. Because of the holes that can store nitrogen fertilizers, zeolite and bovine bone can be utilized as fertilizer coatings. This study was conducted at Universitas Gadjah Mada's Faculty of Agriculture. The research method used was a 2X5 factorial completely randomized design (CRD) with each treatment being repeated 3 times so that the total polybags used were 30 polybags. The first factor was the type of coating material for urea, nano zeolite, and nano bovine bone. The second factor consisted of a dose of coated urea fertilizer with five kinds of dose treatments, which were 0, 100, 200, 300, and 400kg.ha-1. ANOVA was used to analyze parameter data, followed by testing using the DMRT (Duncan's Multiple Range Test). When compared to nano bovine bone, the effectiveness of N removal with nano zeolite generated the best results as a slow-release fertilizer on N uptake. The best N fertilization dose with nano zeolite coating was 200 kg.ha-1, which increased corn plant growth by producing the highest plant height (167.17 cm) and N uptake of 1.6 g/plant. This research can be a recommendation for more effective and efficient Nitrogen fertilization for corn farmers.

Abstract

This study aimed at determining how different rates of poultry manure affected the growth and production of onions (Allium cepa L.) in wet and dry seasons. The experiment was conducted from July to October 2019 and from January to April 2020 at the Department of Crop Science teaching and research farm, University of Nigeria Nsukka, South Eastern Nigeria. The experiment applied a randomized complete block design with nine replications spread over three blocks. The treatments were four doses of poultry manure (0, 10, 20 and 30 t.ha-1) tried in two seasons (wet and dry season). Prior to the investigations, soil analysis of the experimental site and poultry manure nutrient content were carried out. The growth pattern and yield was higher during the wet season. Poultry manure at amount of 30 t.ha-1 gave the best growth attributes (number of leaves, leaf length, and leaf diameter) 14.22, 53.67 cm and 0.88 cm respectively while the 20 t.ha-1 had the highest plant height and bulb fresh weight, 60.86 cm and 2 kg/plant respectively. The trend was not the same as in dry season planting because 20 t.ha-1 poultry manure differs significantly from other rates of poultry manure considered. Plant height, leaf length, leaf diameter and bulb fresh weight (57.64 cm, 55.28 cm, 0.84 cm and 0.63 kg/plant respectively) were statistically significantly (p < 0.05) different at 5% probability level.  Utilization of 20 t.ha-1 of poultry manure and planting in wet season gave the best growth and yield of onion vegetable.

Abstract

Salinization reduces soil health and quality, drastically limiting growth and reducing land degradation and crop yield. This comprehensive research aimed to evaluate the impact of sodium chloride increment on growth factors, amount of oxidative stress biomarker (Malondialdehyde), osmotic response (evaluated by both proline and sugars contents), photosynthesis efficiency (expressed with chlorophyll fluorescence measurement) and activity of Malate dehydrogenases (MDHs) as a regulator under abiotic stress tolerantly in Aloe in Alzahra University, Tehran. Experiments were conducted in two studies at the following concentration of sodium chloride: 0 (control), 100, 200, and 300 (mM) NaCl for 30 days (short-term treatments) and: 0 (control), 54.7, 109.5, and 164.5 (mM) NaCl for 150 days (long-term treatments). Three replications in completely randomized design were applied. The results showed that while the fresh weight of belowground biomass declined at higher salinity level (164.5 mM), no significant differences were reported in the short period of salt treatments. A considerable amount of free proline was accumulated in both short (3.594 µg.g-1 dw) and long ( 2.20 µg.g-1 dw) term studies which raised the role of proline in osmoregulation. Our results showed the decline of MDA amount (0.0003mmol.g-1FW) in 54.7 NaCl (mM) that may be due to less membrane damage in presence of moderate salinity, indicating a variety of dependent differences in biochemical markers activity.
