ABSTRACTApplication of liquid organic fertilizer formula plus on degraded soil to improve the productivity of the land and chili (Capsicum annuum L.) productionSoil exploitation in large numbers occurred in the District Wanaraja of Garut Regency. Excavation of soil more than 2 meters from the top layer for the manufacture of red bricks has exceeded the ability of the soil to re-establish its structure. So that the soils, which were agricultural lands, can be classified as degraded soils with less fertility and chemical properties. Lans reuse for agriculture requires adequate recovery and fertilizer input. This study aimed to determine the formula of LOF (liquid organic fertilizer) plus used with NPK compound fertilizer on degraded soil to improve the soil productivity. The design used was a Simple Randomized Block Design (RBD) by 10 combinations of LOF plus treatment with NPK compound fertilizer as follows: A = Control (degraded soil, no fertilizer), B = 0% LOF + 1 NPK, C = 0.25% LOF + 1 NPK, D = 0.50% LOF + 1 NPK, E = 0.75% LOF + 1 NPK, F = 1.00 % LOF + 1 NPK, G = 0.5% LOF + 3/4 NPK, H = 0.5% LOF + 1/2 NPK, I = 0.5% LOF + 1/4 NPK, J = 0.5 LOF + 0 NPK, and K = 1 NPK of normal soil that all replicated three times. The results showed that the degraded soil of red bricks required concentration of LOF above 0.5% to 1% when applied with 1 dose of standard NPK. It is able to balance the uptake of nutrients P, Ca, and B and percentage of fruitset in chili commodities equivalent to normal soil.Keywords: Chilli, Liquid Organic Faertilizer (LOF), NPK, Soil degrededABSTRAKEksploitasi tanah dalam jumlah yang besar terjadi di Kecamatan Wanaraja, Kabupaten Garut.

The use of high doses of chemical fertilizers in the production of chili (Capsicum annuum L.) has an adverse impact on the environment, especially in dryland. This study aimed to examine the role of cow manure (PKS), goat manure (PKK), chicken manure (PKA), or a combination of two manures in reducing 25% of the requirement for chemical fertilizer on chili plants. One experiment was carried out in the dryland of Gumantar Village, North Lombok Regency, from May to October 2021. Phonska NPK (15-15-15) chemical fertilizer (PK) at a 1,200 kg/ha dose was used as a control. The treatments tested were 75% PK+PKS, 75% PK+PKK, 75% PK+PKA, 75% PK+PKS+PKK, 75% PK+PKS+PKA and 75% PK+PKK+PKA. The dose of manure used in each treatment was 20 tons/ha. All treatments were repeated three times and arranged in a randomized block design. The results showed that the treatment of manure, especially goat manure and chicken manure, increased the available phosphate (P) in the soil. The growth and yield of chili plants were not significantly different in all treatments, which means that manure could replace the role of 25% of the chemical fertilizer used. These results indicate that manure in the long term can reduce the need for chemical fertilizers to produce chili in dryland.  Key words: chili; dryland; manure; chemical fertilizer; nutrition

The success of agricultural development has provided very high support for meeting the food needs of the people of Indonesia, but it is realized that behind these successes there are weaknesses that need to be corrected. Varieties consist of a number of different genotypes, where each genotype has the ability to adapt to the environment. Each variety has a genetic that can affect growth and yield, and the ability to adapt to different varieties. Pruning is an attempt to eliminate some parts of the plant, this is usually related to the cutting of parts of the plant that are diseased, unproductive, or unwanted. The purpose of crop trimming by controlling or directing plant growth is produced. This study aims to look at the effectiveness of peroide trimming on the yield of several chili plant varieties (Capsicum annuum L).                This research was conducted in Sumber Bening village, Selupu Rejang Sub-district from July to October 2016. The chili varieties used in this study were F1, Belinda F1 and Samido F1. This study used a Randomized Block Design (RBD) with 2 factors and 3 replications. Data were analyzed using Variety Analysis (Anava). From the results of the analysis that the Jitu variety has better results than Belinda and Samido varieties. It is assumed that the 30% pruning rate is the ideal level of pruning against growth in plant height, number of fruits and weight of fruit. The treatment of varieties against pruning has no significant effect on all variables

ABSTRACTCrop production can not be separated from the management provided, such as cultivation techniques in determining of water requirements. Water availability determines the success of crop production, either vegetative or generative because water is a basic need for plants. This study was conducted from March to June 2016 in a greenhouse of Cikabayan Experimental Station, Bogor Agricultural University. It consisted of 2 sets of experiment. The first experiment used a red pepper (Capsicum annuum L.) and second experiment used a cayenne pepper (Capsicum frutescens L.). Each experiment was arranged in a single factor randomized block design (RBD) with irrigation level treatment (V) consisted of 5 levels, i.e. v1 = 1 kc.Eo, v2 = 2 kc.Eo, v3 = 3 kc.Eo, v4 = 4 kc.Eo, and v5 = 5 kc.Eo. kc is a plant coefficient and Eo is pan evaporation measured every two days before irrigation. The results showed that the response of red pepper (Capsicum annuum L.) and cayenne pepper (Capsicum frutescens L.) on growth and production parameters were linear. The water requirement of red pepper (Capsicum annuum L.) and cayenne pepper (Capsicum frutescens L.) was still higher than the highest irrigation level of treatment given in this experiment i.e. 5 kc.Eo.Keywords: evapotranspiration, irrigation, number of flowers, plant coefficient, plant heightABSTRAKKeberhasilan tanaman untuk berproduksi secara maksimal tidak terlepas dari pengelolaan yang diberikan seperti teknik budidaya dalam penetapan jumlah air yang dibutuhkan.

Magnetic fields are proven to improve the quality of growth of various plants. In the study, it was examined whether the treatment of magnetic fields on chili seeds (Capsicum annuum. L) infected by Fusarium sp. could maintain plant growth to the generative phase. This research is two-factor research using a randomized block design. The first factor is the 0.2 mT magnetic field induction treatment consisting of 7 minutes 48 seconds (M7), 15 minutes 36 seconds (M15) and control (M0) as control and the second factor is the Fusarium oxysporum infection treatment consisting of 60 minutes infected (F60) and not infected (F0). Each treatment unit was repeated 5 times. Data obtained were analyzed for variance at a 5% significance level. The results of the analysis showed that the treatments in this study did not provide significant differences in carbohydrate content, flowering speed and number of flowers, as well as the fruiting rate of plants from seeds infected with Fusarium sp (M0F60, M7, F60, and M15F60), thus the magnetic field treatment could be causing plants to be resistant to Fusarium sp. so plants from seeds infected with Fusarium sp. able to flower and bear fruit at the same speed and produce the same amount of interest.

In order to study the effects of water stress on the sweet pepper crop, an experiment was conducted in greenhouse. The treatments consisted of soil water content (100%, 85%, 70% and 55% of moisture in the soil field capacity) in a randomized block design with 6 replicates where the experimental units consisted of 16 plants. During the experiment (47, 62, 77 and 92 days after planting) levels of macronutrients (N, P, K, Ca, Mg and S) and micronutrients (B, Cu, Fe, Mn and Zn) present in each plant fraction and the dry mass of plants for the accumulation of these determination were determined. At harvest the number, width and length of fruits from each plant were obtained. Variables were subjected to Tukey test at 5% probability. The water content in the soil interfered significantly with productive variables. To the accumulation of nutrients in the dry matter (leaf + stem) the elements with higher absorption are ordered as follows: K> N> Ca> Mg> S> P and Fe>Mn> Zn> B> Cu. Keywords: Management of irrigation, Capsicum annuum L., water demand.
