Abstract

Cayenne pepper (Capsicum annum L.) is one type of chili that has high demand in Tasikmalaya. To fulfill the consumption, cayenne pepper production is needed to be added. This study helps to determine the best dose of NPK fertilizer that can support the growth yield of cayenne pepper, especially in Tasikmalaya. The research was conducted in experimental field of Agriculture Faculty Universitas Perjuangan Tasikmalaya from November 2022 until February 2023. Experimental design used a randomized block degisn of single factor with six treatments and three replications. The treatments consist of no NPK fertilizer, ( ¼ , ½ , ¾ , 1 and 1 ¼ ) doses of NPK fertilizer.  The results showed that NPK fertilizer had an affect on plant hight with 15.6 cm (3 WAP), 20.4 cm (4 WAP), 24,5 (5 WAP), 27,5 (6 WAP) and 29.5 cm (7 WAP).  The highest cumulative yield of cayenne pepper from  1st until 3th harvests with fruit weight plant-1 was the 1 dose NPK treatment of 358,08 g plant-1.

Abstract

Sea water intrusion is a process where sea water is mixed with underground water around the coast, causing the ground water to become salty because it is contaminated by sea water which is rich in salt. Sea air that enters the ground causes the air to become unfit for consumption and causes the land to become unproductive for planting. People in the Pakis Jaya area, Karawang face difficulties, especially regarding land use for agricultural activities. This is because the land used for cultivating plants is saline soil with a high salt content. Phytoremediation is a method used to clean air or soil contaminated with pollutants, by using the ability of plants to absorb these substances. Cynodon Dactylon and lolium Perenne Brightstar plants are a type of grass that can be used to reduce high salt levels in the soil because these plants are able to live in places with high salinity and also have the ability to reduce salinity by absorbing chloride ions in it. The methods used in this research consisted of: Sampling Process, Plant Acclimatization Stage, Salinity Concentration Test before and after planting grass in Soil Media. The test results showed that the salt content in the soil before planting was 19.20 dS/m and after planting it was 0.02-0.03 dS/M.
