Abstract

Sugarcane is one of the dry land commodities. Biotic and abiotic factors can influence sugarcane growth. Sugar cane can experience disturbances caused by wild plants around it. Weeds are nuisance plants that can decrease sugarcane production. Besides that, the diversity of weeds also has much potential to become a source of food, industry, and medicine. There are 10 species of weeds were found growing at the same time. Through biological identification, it is known that there are 2 types of weeds broad-leaf weeds and narrow-leaf weeds/grasses. Based on observations, the most dominant weed species is Cayratia trifolia. This weed belongs to the broad-leaf type, has a perennial life cycle, and reproduces by root tubers and seeds. Weeds can be controlled effectively using the 0.5% 240SL method. The most appropriate time for weed control in sugarcane is 60-120 hst. In addition, from the literature review, it is known that all weeds have the potential to be used as medicines for human health and also for biological control. So, this really supports science development for advanced use.

Abstract

Increasing the productivity of cayenne pepper (Capsicum frutescens L.) can be done through the use of growth regulators, namely paclobutrazol and liquid organic fertilizer. Treatment of paclobutrazol concentrations and doses of liquid organic fertilizer derived from banana fruit waste is expected to increase the fruit set and storability of the resulting cayenne pepper. The purpose of this study was to determine the best concentration of paclobutrazol and POC banana fruit to increase the fruit set of cayenne pepper, and to determine the best concentration of paclobutrazol to produce cayenne pepper with a more resistant shelf life. The research method used was using a Split Plot Design with the main plot being the dosage of liquid organic fertilizer for bananas, which consisted of NPK 40 g/plant (control), 300 ml/plant POC banana, 400 ml/plant and 500 ml/plant POC bananas. While the concentration of paclobutrazol as a sub-plot, which consisted of 0 ppm/without paclobutrazol (control), 100, 150 and 200 ppm. The results showed that there was a significant interaction between the combination treatment concentrations of paclobutrazol and the dosage of liquid organic fertilizer for bananas in the observed parameter of fruit set percentage. A higher percentage of fruit set was obtained from the combination treatment of 150 ppm paclobutrazol concentration with a dose of 300 ml/plant of banana liquid organic fertilizer. The concentration of paclobutrazol had a significant effect on the storability of cayenne pepper. Cayenne pepper that more resistant to storage were obtained from treatment with a concentration of 150 ppm paclobutrazol.

Abstract

Cucumber (Cucumis sativus L.) is a type of vegetable from the cucurbit family (Cucurbitaceae) that is already popular all over the world. According to history, cucumber plants originated on the Asian continent. Some sources mention the area of origin of cucumber crops is North Asia. This research has been carried out from January to March 2022 at the Green ccHouse located in Slumbung Hamlet RT. 02 / RW. 22 Village. Slumbung Kec. Ngadiluwih Kab. Kediri. The type of soil in this place is sandy loam.This study used a complete randomized design (RAL) with 2 factors. Factor 1 is the influence of the dose of compost from 3 levels and factor 2 is the influence of the dose of phonska fertilizer from 3 levels so that 9 treatments are repeated 3 times, Factor I. Dose of compost organic fertilizer consists of 3 levels, namely: K1 = 5 tons / Ha, K2 = 10 tons / Ha, K3 = 15 tons / Ha, Factor II. The dose of NPK phonska fertilizer consists of 3 levels, namely: P1 = 100 gr / Ha, P2 = 200 gr Ha, P3 = 300 gr / Ha . The observational data were analyzed using a variance analysis (F test) at a level of 5%. If there is an interaction, it is continued with the 5% BNT test, to find out the difference between treatments. The results showed that the combination of treatment of compost doses and doses of NPK phonka fertilizer showed a noticeable difference in plant height, number of fruits and fruit weight in cucumber plants. In a single treatment, the dose of compost did not show any effect on all observation variables. However, the K1 treatment at a dose of 180 gr / plant became the optimal treatment on the variables of the number of leaves stem diameter, fruit weight, and fruit length. However, in the variable plant height and the number of fruits the best treatment in K2 at a dose of 360 gr / plant. The second factor in the treatment of doses of NPK phonska fertilizer has no influence on the growth and yield of cucumber plants. However, in mite treatment such as npk dose phoska P2 with a dose of 7.2gr / plant became the optimal treatment in this study on plant growth variables that followed the length of the plant, the number of leaves and the diameter of the stem. Meanwhile, the yield variables which include the number of fruits, fruit weight and fruit length of the NPK phonska treatment at a dose of 10.8gr / plant is the best treatment.

Abstract

A field experiment to examine the effect of weeding and reducing the number of branches on tomato plants (Lycopersicon esculentum Mill.) on weed diversity and density was carried out in the Griya Santa research area, Lowokwaru District, Malang City with andosol soil type. This experiment was designed in a factorial randomized block design (RBD) with 2 factors and 3 replications. The first factor is: the weeding period (P) which consists of 3 weeding periods, i.e. without weeding (P0), 2 times weeding at 30 and 58 days after planting (P1) and 3 times weeding at 30, 44 and 58 days after planting (P2). The second factor was: pruning the number of tomato plant branches (W) which consisted of 3 levels, namely: Without pruning branches (W0), Pruning branches leaving 2 branches (W1) and Pruning branches leaving 4 branches (W2). All treatment plots were repeated 3 times. The experimental results showed that at 30 DAP (P0W0) there were 2 dominant weeds namely Portulaca oleraceae and Cyperus rotundus. At 44 DAP it showed that there were also 2 dominant weeds namely: Ricinus communis and Cyperus rotundus. The most dominant P2W0 weed treatments were Ricinus communis and Ageratum conyzoides. The P0W1, P1W1, P0W2, and P1W2 treatments had weed species: Ricinus communis and Cyperus rotundus. The dominant weeds found in the P2W1 and P2W2 treatments were Ricinus communis and Portulaca oleraceae.

Abstract

Bacillus sp. is one of the Biological Control Agents (BCA) that has effectiveness in inhibiting pathogenic bacterial and fungal pathogens. The purpose of this study was to determine the presence of Bacillus sp. on bamboo and tomato root soil. The research stage started from the exploration stage which was carried out on agricultural land in Made Village, Sambikerep District, Surabaya City. Soil sampling was taken compositely at 5 different points. From the isolation results, 6 bacterial colonies were found which were suspected to Bacillus sp. The six isolates were BS 1, BS 2, BS 3, BS 4, BS 5, and BS 6. Of the six colonies, only BS 3 colonies could not grow. The results of the isolation were then identified by colony morphology, physiological and biochemical characteristics. The results of the gram test showed that BS 2, BS 4, and BS 6 were gram-positive. The results of the soft rot test showed that BS 6 showed a positive reaction. So that it is suspected as Bacillus sp. are BS 2 and BS 4.
