Abstract

Penelitian ini bertujuan untuk melihat pengaruh varitas umbi kentang dan jarak tanam terhadap hasil umbi kentang di dataran tinggi Kabupaten Rejang Lebong. Penelitian menggunakan Rancangan Acak Kelompok Faktorial, dengan uji BNT pada tingkat signifikan 5%. Perlakuan eksperimental menggunakan dua factor yaitu varitas (V) dan jarak tanam (J). Faktor perlakuan pertama Varitas umbi kentang (V) terdiiri tiga varitas yaitu V1 = varitas granola, V2 = varitas atlantic dan V3 = diseere. Faktor kedua perlakuan jarak tanam (J), terdiri tiga tingkatan yaitu J1 = 80 cm x 20 cm, J2 = 80 cm x 25 cm, J3 = 80 cm x 30 cm. Berdasarkan analisis varians perlakuan varitas berpengaruh terhadap bobot umbi perbuah dan jumlah umbi pertanaman. Sedangkan perlakuan jarak tanam tidak berpengaruh terhadap semua variable diameter umbi, jumlah umbi, bobot umbi perbuah dan bobot umbi pertanaman. Selanjutnya uji lanjut BNT pada taraf signifikan 5 persen, perlakuan varitas diseere (V3), berbeda nyata dengan varitas granola (V1) dan varitas atlantic (V2), terhadap bobot umbi perbuah. Sedangkan uji BNT 5 persen, perlakuan varitas atlantic (V2) berbeda nyata dengan varitas granola (V1) dan varitas atlantic (V2) terhadap jumlah umbi pertanaman. Kesimpulan : Penggunaan varitas diseere menghasilkan bobot umbi yang besar perbuah dan varitas atlantic memperoleh jumlah buah terbanyak pertanaman. Kata Kunci : Varitas, jarak tanam dan umbi kentang.

Abstract

Peanut productivity in Bengkulu Province in 2021 is 2,498 tonnes/ha. However, the productivity of peanuts is still low compared to the average national productivity, which has an average production of around 3,595 tonnes/ha. Soil fertility is an important factor for farming. For this reason, it is necessary to take appropriate actions, one of which is to improve soil nutrients, one of the actions taken is liming the soil. Apart from that, fertilization is also important to note in increasing peanut production by using pearl NPK doses. Pearl NPK is one of the inorganic fertilizers. This study aims to determine the best dosage of dolomite and pearl NPK fertilizer on the growth and yield of peanuts. This study used a randomized block design (RBD) using 2 treatment factors with 4 levels and 4 repetitions, each repetition consisting of 4 plants. Then 16 combinations were obtained, with the total plants used, namely: D×N×T×U= 4×4×4×3= 192. The data obtained were analyzed using ANOVA and continued with 5% DMRT. The results showed that the dose of dolomite was 200 grams and 50 gram pearl NPK fertilizer has an effect on the observed variables, namely plant height, number of leaves, number of flower strands, number of pods, wet weight, and dry weight. Based on the results of ANOVA, it can be concluded that dolomite has an effect on the growth and yield of peanuts, NPK pearl fertilizer treatment has an effect on the growth and yield of peanuts, the interaction of dolomite and NPK pearl fertilizer has an effect on the growth and yield of peanuts.
