Abstract

This study aimed to determine the effect of chicken eggshell organic fertilizer pellets (POPe) and NPK on the growth and yield of tomato plants. The research was conducted at the Experimental Garden of the Faculty of Agriculture, Wijaya Kusuma University Surabaya from April to August 2022. The experiment used a Randomized Block Design (RBD) factorial with two factors, namely: Factor (1) POPe chicken eggshell (P) and Factor (2) NPK dose (K). Each treatment was repeated three times with P0 (without POPe treatment), POPe chicken eggshell treatments consisted of P1 (7.5 gr POPe), P2 (15 gr POPe), P3 (22.5 gr POPe) and K0 (without NPK dose), NPK fertilizer doses of K1 (9 gr NPK). The results showed that the use of POPe and NPK on tomato plants had no effect on their growth and yield.

Abstract

The aim of this study was to determine the Alellopathy Potential contained in Imperata cylindrica extract as a Bio-herbicide. The research was conducted at the Experimental Garden of the Faculty of Agriculture; Wijaya Kusuma Surabaya University. This research method used completely randomized design (CRD); with 4 treatments and 6 replications. The treatments are (A0): Control; A1 : extract concentration ( 250 g/L) ; A2 : 500g/L ; (A3); 750 g / L. Observational data were analyzed using Analysis of Variant (ANOVA), then tested with 5% BNT. The results showed allelopathy contained in the extract of Imperata cylindrica L. can suppress weed seed germination up to 94.67 %; and has a negative effect on the initial growth of spiny spinach (Amaranthus spinosus L) seedling sprouts. With treatment A2 and A3 ; All weed seeds that were able to germinate grew abnormally (100%). Imperata cylindica extract has the potential to be used as a bio-herbicide (natural herbicide) to suppress the early growth of weed seeds on spinach spines.

Abstract

The aims of this research are: (1) to predict the damage of soybean pod through the mathematical model of relationship between population density of N. viridula and pod damage, (2) to predict the soybean yield through the mathematical model of relationship between population density of N. viridula and pod damage where made by modification of Reynolds Transport Theorem. This research was used Completely Randomized Design with nine treatments and each was replicated three times. The treatment were : P0 = control, P1 = 1 nymph, P2 = 2 nymphs, P3 = 3 nymphs, P4 = 4 nymphs, P5 = 1 adult, P6 = 2 adults, P7 = 3 adults, and P8 = 4 adults. The population density of pod sucking bug was the independent variable, while dependent variables were : rate of pod damage, and dry pod weigh. Analysis of mathematical modeling was made by approaching of Continuum Theory and Reynolds Transport Theorem. The results showed that : (1) Relationship between population of N. viridula and pod damages in the form of mathematical model which is used to predict the soybean pod damage has error 0,02 – 0,10%, and (2) Mathematical model where made by modification of Reynolds Transport Theorem which is used to predict the soybean yield has error 0,01 – 1,00%.

Abstract

The weed known as "Alang-alang" (Imperata cylindrica) has narrow leaves and grows in upright clusters. The allelopathic chemicals contained in alang-alang have a negative effect on the germination and early growth of other plants. The purpose of this research is to determine whether alang-alang has a negative effect on the germination and early growth of mung bean plants. The Laboratory of the Faculty of Agriculture, Wijaya Kusuma University, Surabaya, was the location of this research, conducted from November 2023 to January 2024. The research was conducted in the laboratory to test seed viability and in the field (planting in polybags) to test the early growth of plants. The research used a Completely Randomized Design (CRD), with 4 treatments: A0, which is water control; A1: 50 grams/ liter of water ; A2: 100 grams /liter of water; A3: 150 grams /liter of water; with 6 replications. The results of this research show for laboratory research: (1) the addition of extra alang-alang allelopathy did not significantly affect the germination of mung beans but the germinated seeds were able to grow abnormally. The allelopathy treatment test from 50 to 150 g/L of water; the tested mung bean seeds still grew 100%, but 91% to 100% of the seedlings became abnormal. (2) The addition of extra alang-alang allelopathy in polybag research did not affect the growth of the number of seedlings, seedling height, number of leaves, but negatively affected stem diameter and plant wet weight.

Abstract

Planting sunflowers more densely was intended to maximize the use of nutrients, water and light so that you will get maximum results, but populations that were too dense or too low will not provide maximum results. The research aims to obtain the optimal planting distance and number of plants per hole to obtain high quantity and quality results. The research used a Randomized Completly Block Design (RCBD) factorial experiment consisting of two factors with the first factor being the planting distance in rows with four levels, namely J1 = 25 cm, J2 = 30 cm, J3 = 35 cm, and J4 = 40 cm, while the factor second is the plant population per planting hole (P) which consists of 2 levels, namely P1 = one plant per planting hole and P2 = two plants per planting hole. There were 8 experimental treatments which were repeated 3 times, arranged in a randomized completely block design. The research results concluded that there was no interaction between the plant spacing treatment factor and the number of plants per planting hole treatment factor for all research variables except plant height. The highest plant height value was at a shorter planting distance, namely 25-30 cm with one plant per planting hole. The variables number of leaves, flower diameter and flower weight had the highest values ​​in one plant per planting hole. For farmers who want to grow sunflowers, it was recommended to plant one plant per planting hole, the planting distance can be narrowed to get the ideal plant population.

Abstract

Nut grass is defined as a weed that can reduce agricultural yields because it contains allelopathic compounds which have a negative impact on the sprouts and initial growth rate of spinach weed. The written research aims to find out whether allelopathic extracts from sedge grass can influence the germination and initial growth of thorn spinach weed. The research was carried out using a Completely Randomized Design (CRD) consisting of four treatments, each repeated six times. The treatment is defined as: A0 as a control with water, A1 with 50 grams of tekhi per liter of water, A2 with 100 grams of tekhi per liter of water, and A3 with 150 grams of tekhi per liter of water. The results of the study showed that in treatment A3 (150g tekhi/L water) on the last day, the allelopathic extract of tekhi caused abnormalities in 75.17% of spinach spinach seed sprouts. In polybags, A3 treatment (150g tekhi/L water) on the last day reduced the growth rate of the number of seedlings from 25 plants to only 1 plant (96%), with a seedling height of 1 cm and a number of leaves of 3.67 pieces. The higher the treatment dose, the greater the effect in suppressing germination and initial growth of thorn spinach weed.

Abstract

In order to reduce the use of inorganic pesticides which have been proven to pollute the environment and endanger consumers, it is necessary to develop pesticides from plant materials. This study aims to obtain and determine the effect of bintaro plant extract on the development of grower worm (Spodoptera litura). The treatments consisted of 4 combinations of bintaro organs (leaves, bark, fruit flesh, and seeds) and 5 combinations of extract concentrations (2.5%, 5.0%, 7.5%, 10.0%, and 12.5%) so that there are 20 combinations and one control is repeated three times. This research was conducted at the Merdeka University Surabaya laboratory from April to May 2020 using a Completely Randomized Design (CRD). The results showed that the extract of the bintaro plant had no significant effect on the instar development of the grower worm (Spodoptera litura). Bintaro plant extract had a significant effect on the mortality of grower worm (Spodoptera litura) on days 15 to 20, while on the development of life it had a significant effect on days 12 to 20.
