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

Insect pests are organisms that can damage plants and have a high level of damage. However, it is not only insects that need to be watched out for but also the microorganisms they carry inside and outside their bodies. These insects are referred to as vectors. Ambrosia beetle is a plant vector that carries both saprophytic and pathogenic fungi. There is little information about ambrosia beetles and the mushrooms they carry, so they need to be studied further. This study aimed to determine the fungi associated with the ambrosia beetle on Angsana trees (Pterocarpus indicus). The research used purposive sampling by examining the symptoms and signs of an ambrosia beetle attack. The identification process is based on morphological forms and entomology manuals. The results obtained based on morphological identification showed that the ambrosia beetle came from the genus Cryphalus sp. In contrast, the associated fungus comes from the genus Geosmithia sp. It is known that the fungus Geosmithia sp. can act as a pathogen so that it can damage Angsana trees.

Abstract

Flower and fruit loss and low fruit quality are complex problems faced in star fruit cultivation. The research aims to determine the effect of pruning twigs and applying foliar fertilizer on plant growth, quantity and quality of fruit. Factorial research using two treatment factors. . Factor I is the type of foliar fertilizer, consisting of D0 = No foliar fertilizer (control), D1 = SB foliar fertilizer (8-20-15), D2 = HP foliar fertilizer (10-40-15), and D3 = DN foliar fertilizer (10-30-37). Factor II is the interval for applying foliar fertilizer, consisting of I1 = once every 7 days interval, I2 = once every 10 days interval, and I3 = once every 14 days interval. The research used plant material of the same age, as replications, groups of plants were used that were differentiated according to the pruning model, namely P0 = Plants that were not pruned as replication I, P1 = Plants that only had their wiwilan branches pruned as replication II, and P2 = Plants that had their branches pruned wiwilan and clustered branches (remaining the good ones) as repetition III. The results showed that application of foliar fertilizer and pruning of branches increased the number of fruit, fruit weight and size of sweet star fruit. Pruning wiwilan branches and reducing clustered branches has the greatest effect on the number of fruit, fruit weight and fruit volume compared to other pruning intensities. The research results can be used as a reference for star fruit farmers in determining maintenance actions, especially in fertilizing and pruning to regulate the canopy. while increasing production.
