Abstract

Galleria mellonella L. (Lepidoptera: Pyralidae) is a significant international pest and the most devastating pest throughout the world of beeswax. Natural pesticides must be replaced with synthetic materials since they are more ecologically friendly. This study aims to determine alternative methods of controlling the larger wax moth by assessing the efficacy of several plant-based biocides for this purpose various ethanolic plant extracts such as rosemary (Rosmarinus officinalis L), Clove (Syzygium aromaticum), Eucalyptus (Eucalyptus sp) and Cinnamon (Cinnamomum verum) where used with four extraction rates (5,10,15 and 20) against the late instar larvae of Galleria mellonella in vitro after 24,48 and 72 hr. Obtained results revealed that the pupal mortality increased when the concentration increased and the highest accumulative mortality percentage of wax moth larvae during the experiment, it was demonstrated that all studied plants were efficient at suppressing Galleria mellonella larvae. The result shows that three days after application treatment of rosemary 20% gave the maximum total mortality percentage (%100) followed by (%96.58, %92.66 and %64.86) for Eucalyptus, Cinnamon and clove after 24,48 and 72 hr. respectively. It may be suggested that spraying natural products is a good option on new wax combs to protect them against infestation by wax moth larvae

Abstract

This study assesses the adaptation of smallholder farmers to climate extremes and its contributing factors in Zambia’s southern province. The study employed primary data collected from 270 smallholder farmers, and these constituted the sample size.  According to the study's findings, change crop variety was adopted by 43% of the farmers. Other strategies of adaptation that were employed include; agricultural insurance, change sow/harvest date, crop diversification and soil conservation.   The findings also showed that the various strategies of adaptation (agricultural insurance, change sow/harvest date, crop diversification and soil conservation), correlated positively with age, education, distance, farming experience, ownership of a radio, an ox, a plough, and extension source. The study makes the following recommendations; (a) enhancing the education and awareness level of farmers towards climate extreme, (b) improving farmers’ access to agricultural assets (plough, oxen etc), and (c) when developing and implementing adaptation strategies, farming experience should be taken into account.

Abstract

The demand of organic cultivation of plants is increasing and soil application of organic fertilizer reduces the hazardous usage of inorganic fertilizer and Humic acid is an organic compound derived from plant and animal residues and microbial cells with long-term physical, chemical, and biological processes. In addition, ultivation of soybean in Kurdistan region is not in a wide value therefore, the objective of this study was to determine the impact of soil application of different rates of Humic acid as an organic fertilizer on the growth characteristic of soybean cultivated and determining the best cultivation period for soybean growth. The experiment was conducted in randomized complete block design with two factor treatments and 3 replication, the first factor was one dose soil application of four different  Humic Acid rates (HAR) which were (0 (control), 2,4,6,8 g/L) and two cultivation period (CP) which were cultivation Period 1 (CP1) on 15 May 2022 and cultivation Period 2 (CP2) on 1st of  June 2022. Observations were made against the growth parameters of plant height number of branches, leaf area, root length, shoot fresh weight and shoot dry weight. The  effect of soil application of humic acid rates (HAR) was highly  significant on the plant height and root length and significant on the No. of branches, shoot fresh and dry weight. While, cultivation period insignificantly affected the growth parameter except for leaf area.  was significant. The maximum plant height, number of branches, leaf area, root length, shoot fresh and dry weight were observed with soil application of 8 g/L of humic acid  which were (82.83 (cm), 23.33, 8815 (mm2), 68.83 (cm), 503.33 (g) and 190.00 (g) respectively. The highest plant height (72 cm), number of branches (18.87), leaf area (7714 mm2), root length (57.13 g), shoot fresh (263.67 g) and dry weight  (102.93 g) were observed when the planted cultivated in 1st   period (CP1) compared to CP2.

Abstract

This research aims to determine the effect of various types of organic fertilizer on the growth of agarwood seedlings (aquilaria malaccensis lamk). This research was conducted in August to November 2022. This study was conducted at Arboretum of the Faculty of Forestry. Tadulako University Palu. This research uses a complete random design (RAL) consisting of 3 treatments namely K1 (Control) K2 (DOAMI Organic Fertilizer) K3 (Gresik Organic Fertilizer). The results showed that the administration of various types of organic fertilizer had a significant effect on high increase and seedling diameter, but did not significantly affect the increase in the number of leaves. K2 treatment gives better results than other treatment. Average of seed height K1 = 4.5, K2 = 7.75 k3 = 6.75, the average increase in the diameter of the seedlings is K1 = 0.37 K2 = 0.72 k3 = 0.45. The average increase in the number of leaves of K1 = 6, K2 = 10.25, K3 = 7.75.

Abstract

The purpose of the study is to find out the process of cultivating shallots using hydroponic techniques. The location of the study was conducted in Kedamean District, Gresik Regency, precisely Turirejo Village, which has fresh hydroponic Micro, Small and Medium Enterprises (MSMEs). The determination of the location of the study was carried out purposively, namely carried out on fresh hydroponic MSMEs with a business of cultivating shallot commodities hydroponically without using green houses or shade. The data used by researchers are primary and secondary data. The research method uses a descriptive method that uses survey methods, in-depth interviews and observations as data collection techniques. The results of the analysis of the hydroponic cultivation process of fresh hydroponic MSMEs are cultivating hydroponic shallots with the Nutrient Film Technique (NFT) system. It consists of 2 stages including, seedbed installation and enlargement installation. The cultivation process is carried out in an open place, namely the yard of the house or not using a greenhouse. The hydroponic cultivation process in fresh hydroponic MSMEs starts from the preparation of cultivation, the process of cultivating shallot hydroponics and post-harvest handling. Preparation for hydroponic cultivation of shallots includes capital, land, labor and saprodi. The next stage is in the cultivation process, including 1) Seeding seedlings, 2) Transplanting, 3) maintenance: (fertilization embroidery, watering, opt control) 4) Harvesting. Post-harvest handling in the hydroponic cultivation of shallots, namely withering and drying.

Abstract

Low soil fertility is a limiting factor for crop production in general. Increasing the yield of garlic with balanced fertilization is an important key identified, also the right type and dose of fertilization is also a major problem. The purpose of this study was to determine the effect of inorganic fertilizer (nitrogen) and chicken manure doses on the growth and yield of garlic. The experimental design used in this research was a completely randomized design. The first factor was chicken manure, which consists of two levels, i.e., without chicken manure and 40 t/ha of chicken manure. The second factor was the dosage of N fertilizer which consists of twenty levels, ie, no fertilizer, urea with a dose of 50, 100, 150, 200, 250, 300, 350, 400. 450, 500 kg/ha, ZA with a dose of 50, 100, 150, 200, 250, 300, 350, 400. 450, 500 kg/ha. The results showed that the combination of urea fertilizer 500 kg/ha and chicken manure 40 tons/ha gave the highest yield of stored dry tubers and was significantly higher than control plots and other treatment combinations. Likewise other growth and yield parameters increased progressively. Therefore, it can be concluded that to increase the yield of garlic in the study area, 500 kg/ha of urea fertilizer and 40 tons/ha of chicken manure are needed. The recommendation is that on Andisol soil for garlic cultivation, it is better to use a combination of 500 kg/ha urea and 40 t/ha chicken manure.
