Abstract
Tanaman cabai rawit (capsicum frutescens) merupakan salah satu dari komoditas tanaman sayuran yang popular di Indonesia. Cabai rawit dapat digunakan sebagai bahan bumbu dapur, bahan utama industri saus hingga industri farmasi. Seiring dengan permintaan akan komoditas tersebut terus mengalami peningkatan, namun produktivitas dan kepemilikan lahan oleh petani semakin menurun. Dalam mengatasi masalah tersebut upaya yang dapat diberikan adalah pengaplikasian PGPR (Plant Growth Promoting Rhizobacteria) dan pengelolaan sistem tanam. Sistem tanam yang digunakan yaitu sistem tanam monokultur dan tumpang sari. Tujuan dari penelitian ini adalah untuk mempelajari pengaruh PGPR terhadap Pertumbuhan dan hasil tanaman cabai rawit pada sistem tanam monokultur dan tumpangsari. Hipotesis dari penelitian ini adalah terdapat interaksi antara PGPR terhadap Pertumbuhan dan hasil tanaman cabai rawit pada sistem tanam monokultur dan tumpangsari. Penelitian dilakukan di lahan kebun buah dan sayuran Kampung Pelangi RW 09 Kelurahan Merjosari Kecamatan Lowokwaru, Kota Malang pada bulan September sampai November 2021. Alat yang digunakan selama penelitian yaitu berupa cangkul, sekop, meteran, timbangan analitik, ember, gelas takar, selang, kamera, penggaris, oven, Leaf Area Meter (LAM), lux meter dan alat tulis. Bahan utama yang dibutuhkan adalah bibit cabai rawit varietas Dewata F1 dengan tipe indeterminate, pupuk kandang murni dengan kotoran sapi, air, dan PGPR (Plant Growth Promoting Rhizobacteria). Penelitian ini menggunakan rancangan tersarang dengan dua faktor yaitu konsentrasi PGPR (Plant Growth Promoting Rhizobacteria) dan sistem penanaman. Faktor pertama adalah perlakuan pemberian konsentrasi PGPR (Plant Growth Promoting Rhizobacteria) yang terdiri dari 4 taraf, yaitu P0: tanpa PGPR (Plant Growth Promoting Rhizobacteria), P1: 10 ml/l, P2: 20 ml/l, P3: 30 ml/l. Faktor kedua adalah perlakuan aplikasi sistem penanaman yang terdiri dari 2 taraf, yaitu T1: Monokultur, T2: Tumpangsari dengan tanaman pepaya. Terdapat 8 kombinasi perlakuan konsentrasi PGPR (Plant Growth Promoting Rhizobacteria) dan perlakuan sistem tanam, setiap perlakuan diulang 4 kali sehingga terdapat 32 petak percobaan. Parameter yang diamati yaitu : tinggi tanaman, jumlah daun, luas daun, umur berbunga, bobot segar total tanaman, bobot kering total tanaman, laju pertumbuhan tanaman, jumlah buah per tanaman, bobot buah per tanaman, dan bobot buah panen per hektar. Data hasil pengamatan selanjutnya dianalisis menggunakan analisis ragam (ANOVA) dari Rancangan tersarang dengan taraf 5%. Hasil analisis yang menunjukkan pengaruh nyata akan dilakukan uji lanjut dengan menggunakan uji beda nyata terkecil (BNT) pada taraf 5%. Berdasarkan hasil penelitian menunjukkan bahwa terdapat interaksi nyata antara sistem tanam dan PGPR terhadap hasil pengamatan tinggi tanaman, jumlah daun, luas daun, umur berbunga, bobot segar total tanaman, bobot kering total tanaman, laju pertumbuhan tanaman, jumlah buah per tanaman, bobot buah per tanaman, dan bobot buah panen per hektar. Hasil dari masing-masing pengamatan vii cenderung mengalami peningkatan hasil pada tiap-tiap parameternya seiring dengan ditingkatkannya konsentrasi PGPR yang diberikann dan tanaman cabai rawit yang ditanam secara monokultur juga cenderung menghasilkan hasil yang lebih tinggi dibandingkan dengan tanaman cabai rawit yang ditumpangsarikan dengan tanaman pepaya umur 3-4 bulan
English Abstract
Cayenne pepper (Capsicum frutescens) is one of the most popular vegetable crops in Indonesia. Cayenne pepper can be used as a spice in the kitchen, the main ingredient in the sauce industry to the pharmaceutical industry. Along with the demand for these commodities continues to increase, but productivity and land ownership by farmers is decreasing. In overcoming this problem, the efforts that can be given are the application of PGPR (Plant Growth Promoting Rhizobacteria) and the management of the planting system. The cropping system used is a monoculture and intercropping system. The purpose of this study was to study the effect of PGPR towards growth and yield of cayenne pepper on monoculture and intercropping systems. The hypothesis of this study is that there is an interaction between PGPR towards growth and yield of cayenne pepper on monoculture and intercropping systems. This research was conducted in the fruit and vegetable garden of Kampung Pelangi RW 09, Merjosari Village, Lowokwaru District, Malang City from September to November 2021. The tools used during the research were hoe, shovel, meter, analytical scale, bucket, measuring cup, hose, camera. , ruler, oven, Leaf Area Meter (LAM), lux meter and stationery. The main ingredients needed are cayenne pepper seeds of Dewata F1 variety with indeterminate type, pure manure with cow dung, water, and PGPR (Plant Growth Promoting Rhizobacteria). This study used a nested design with two factors, namely the concentration of PGPR (Plant Growth Promoting Rhizobacteria) and the planting system. The first factor was the treatment with a concentration of PGPR (Plant Growth Promoting Rhizobacteria) which consisted of 4 levels, namely P0: without PGPR (Plant Growth Promoting Rhizobacteria), P1: 10 ml/l, P2: 20 ml/l, P3: 30 ml/l. The second factor is the application treatment of the planting system which consists of 2 levels, namely T1: Monoculture, T2: Intercropping with papaya plants. There were 8 combinations of PGPR (Plant Growth Promoting Rhizobacteria) concentration treatment and cropping system treatment, each treatment was repeated 4 times so that there were 32 experimental plots. Parameters observed were: plant height, number of leaves, leaf area, age of flowering, total fresh weight of plants, total dry weight of plants, plant growth rate, number of fruit per plant, fruit weight per plant, weight of harvested fruit at harvest plots and weight of harvested fruit per hectare. The observational data were then analyzed using analysis of variance (ANOVA) from the nested design with a level of 5%. The results of the analysis that show a significant effect will be further tested using the smallest significant difference test (BNT) at the 5% level. Based on the results of the study showed that there was a significant interaction between the planting system and PGPR on the results of observations of plant height, number of leaves, leaf area, flowering age, total fresh weight of plants, total dry weight of plants, plant growth rate, number of fruits per plant. plants, weight of fruit per plant, and weight of harvested fruit per hectare. The results from each observation tended to increase in yield for each parameter ix along with the increase in the concentration of PGPR given and cayenne pepper plants grown in monoculture also tended to produce higher yields compared to cayenne pepper plants intercropped with papaya plants aged 3- 4 months
