Abstract

ABSTRAK Penerapan sistem tanam tumpangsari pada tanaman belum menghasilkan (TBM) kelapa sawit merupakan upaya optimalisasi lahan. Pada TBM I  terdapat 75 % ruang terbuka yang dapat ditanami tanaman sela, misalnya tanaman cabai. Tanaman sawit umumnya ditanam pada lahan marginal, maka untuk optimasi pertumbuhan tanaman sela perlu dipilih varietas yang baik dan dilakukan pemupukan. Penelitian bertujuan untuk memperoleh pengaruh interaksi terbaik varietas dan dosis pupuk hayati terhadap pertumbuhan dan hasil tanaman cabai yang ditanam pada pertanaman kelapa sawit TBM 1. Percobaan dilakukan mulai Oktober 2017 sampai Pebruari 2018 di Kebun Percobaan Fakultas Pertanian, Universitas padjadjaran.  Ordo tanah inceptisol. Tipe curah hujan C menurut klasifikasi Schmidt dan Ferguson, ketinggian tempat ± 780 m dpl. Rancangan menggunakan Split plot design,  varietas sebagai main plot terdiri atas dua taraf, yaitu CK5 dan CB2 dan dosis pupuk hayati sebagai sub plot terdiri atas enam taraf, yaitu 0, 50, 100,150, 200 dan 250 mL/tanaman. Setiap perlakuan diulang empat kali. Hasil penelitian menunjukkan Pertumbuhan dan hasil tanaman cabai dipengaruhi secara mandiri maupun interaksi varietas dan dosis pupuk hayati. Pada CK5 taraf dosis pupuk hayati 200 mL/tanaman menghasilkan tinggi tanaman, lebar kanopi dan jumlah cabang yang lebih baik. Pada CB2, taraf dosis 150 mL/tanaman memberikan pengaruh interaksi lebih baik. Secara mandiri, dosis pupuk hayati 150 mL/tanaman menghasilkan pertumbuhan terbaik pada tinggi tanaman, lebar kanopi, jumlah cabang, bobot dan jumlah buah tanaman cabai, sementara untuk varietas CK5 menghasilkan tinggi tanaman, jumlah cabang, panjang dan jumlah buah yang lebih baik dibanding CB2.Kata kunci : Tumpangsari, varietas cabai, pupuk hayati. ABSTRACT Intercropping system on immature plant of oil palm is an alternative cropping system to reach land optimization. In immature oil palm plantation there is 75% uncover space among the crops which could be used for cultivating annual crops. Generally, oil palm is cultivated on marginal land, so that to optimize the growth of annual crop is needed proper variety and fertilization. The objective of this research was to get the best interaction effect among variety and dosage of organic fertilizer at year 1 immature palm. The experiment was conducted at experimental station of Agricultural Faculty, Universitas Padjadjaran from Oct 2017 to Feb. 2018, it used of split plot. Variety was a main plot with two level namely: CK5 and CB2, the dosage of organic fertilizer was a sub plot with six level namely: 0, 50, 100, 150, 200, and 250 mL of organic fertilizer. All treatments were repeated for four times. The growth and yield of chili crop were affected independently by variety or fertilizer dosage even by interaction of both. CK5 and 200 mL of fertilizer showed better on plant height, canopy width, and number of branch, whereas interaction effect of CB2 and 150 mL of fertilizer showed the best on plant growth. Independent effect of organic fertilizer of 150 mL affected on plant height, canopy width, branch number, fruits number and weight of chill crop. Independent effect of variety of CK5 showed better than of CB2 on plant height, fruit number and yield.Keywords : Intercropping, Chili Variety, Organic Fertilizer

Abstract

Sub soil is soil under the top soil layer, with low fertility. The use of sub soil as an Arabica coffee seedling planting media needs to be considered because the top soil layer has been much reduced by erosion or run off. Needs modification in sub-soil soils to increase fertility. Increased sub soil fertility can be done using organic materials, both solid and liquid. Coffee seedling using the right planting media will determine the growth and production of coffee in the field later. The purpose of this study was to determine the use of subsoil growing media with the addition of organic material for the growth of Arabica coffee seeds. The experiment was conducted at the Ciparanje Experimental Field, Faculty of Agriculture, Padjadjaran University, Sumedang Regency, in March to June 2019 with altitude of ± 780 meters above sea level. The experiment used a randomized block design (RBD) with 9 treatments repeated three times. The treatments are as follows: 100% topsoil; subsoil 100%; topsoil: chicken manure (2: 1); subsoil: chicken manure (1: 1); subsoil: chicken manure (2: 1); subsoil: chicken manure (3: 1); subsoil + 25% coconut water; subsoil + 50% coconut water; subsoil + 75% coconut water. The results showed that the modification of subsoil with the addition of organic matter affected the growth of Arabica coffee seedlings on stem diameter variables of 8 MST and leaf chlorophyll index of 16 MST. Subsoil media with the addition of chicken manure (3: 1) had a good effect on leaf chlorophyll index and subsoil media with 25% coconut water had a good effect on the diameter of Arabica coffee seedling stems. Subsoil can replace topsoil by adding organic matter.
