Abstract

The increase in market demand red spinach (Amaranthus Gangeticus) makes the prospects very promising less than optimal for the growth of red spinach (Amaranthus Gangeticus) because soil fertility is low so that the provision of organic material can improve soil fertility through the improvement of the physical, chemical, and biological soil so that it can support the growth of red spinach. This study aims to determine the dose of manure, the dosage of rice husk ash as well as the interaction of dosage that is optimal for the growth and yield of red spinach.this research was conducted experimental farm of the faculty of science and technology with a height of 28 meters above sea level Labuhanbatu district in March to October 2020. Research design using group factorial consisting of two factors. The first factor, namely the granting of cow manure (L) with three levels, namely : L0 = 0 ton/ha (control) L1 = 2 ton/ha, equivalent to 200 g/m2 (the recommended dose), L2 = 4 ton/ha, equivalent to 400 g/m2, L3 = 6 ton/ha, equivalent to 600 g/m2. The second factor, rice husk ash (A) consists of 4 levels, namely : A0 = 0 ton/ha (control), A1 = 1 ton/ha equivalent to 50 g/m2 (the recommended dose), A2 = 1.5 tons/ha, equivalent to 75 g/m2.The Parameters measured were plant height (cm), number of leaves (strands), Weight per Plant Sample (g). The results showed that the administration of cow manure 4 ton/ha, equivalent to 400 g/m2 can increase plant height, leaf number, and weight per Plant of amaranth red. The provision of 1.5 tons/ha, equivalent to 75 g/m2 can increase plant height, the number of leaves plant red spinach (Amaranthus Gangeticus).Keywords: Rice Husk Ash, Red Spinach, Cow Manure, Plant Growth

Abstract

This ecosystem change results in changes in chemical, physical, and biological characteristics and properties. The fertility level of peatlands can be determined through an analysis of the chemical properties of the soil. Therefore, the analysis of the chemical properties of the soil, including the analysis of the main nutrient content, was carried out from November 2021 to January 2022 in Simpang Kanan Village, Simpang Kanan District, Rokan Hilir Regency, Riau Province. Farmers in Simpang Kanan Village use marginal land, that is peat soil to develop oil palm farming. This research was conducted using the free grid method at the semi-detailed survey level. The implementation of taking soil samples from 3 sample points with a distance of 100 meters in the field using a random method scattered at predetermined points. Farmers in Simpang Kanan Village use marginal peat soil to cultivate oil palm plantations. So far, no analysis of the chemical properties of peat soil has been carried out. Application of fertilizers and cultivation is only based on knowledge from the internet or from previous generations. Therefore, it is important to study the analysis of the chemical properties of soil from peatlands used for oil palm plantations. The results of research on the chemical properties of peatlands in Simpang Kanan Village, Simpang Kanan District, Rokan Hilir Regency, Riau Province showed that the peat soil planted with oil palm in Simpang Kanan Village had a pH of around 4.89, C-organic 6.07%, N-Total 1 ,67 mg/L , P-Total 34.08 mg/L , K-Total 11.54 mg/L. Thus, the chemical properties of the soil in oil palm plantations in Simpang Kanan Village, Simpang Kanan District, Rokan Hilir Regency, Riau Province. Still good, to increase fertility for oil palm cultivation, it can be done by increasing the pH in the soil so that it maximizes oil palm development and can be used as a recommendation for oil palm fertilization.

Abstract

Potassium is a macro nutrient that can affect the quality and quantity of oil palm bunches as well as resistance to disease and drought stress. So far, testing the status of potassium nutrient uptake in people's plantations in Perlabian Village, Kampung Rakyat Labuhanbatu Selatan District has never been carried out. Fertilization and maintenance are carried out through knowledge from generation to generation, so it is important to have a study on the nutrient uptake status of potassium in oil palm leaves. This research was conducted using a free grid survey method at the semi-detailed survey level with a density of 100 meters. A total of 6 leaf samples were taken on the 17th leaf midrib and then rubbed with 70% alcohol and then put into the plastic sample for further testing in the laboratory of PT. Socfindo. The results showed that the potassium in leaf samples 1, 3 and 4 experienced deficiency and leaf samples 2, 5 and 6 were at the optimum. In oil palm plantations in smallholder plantations in Perlabian Village, Kampung Rakyat Subdistrict, it shows that the total K content of leaves is included in the optimum category.
