Abstract

The productivity and quality of red chili are greatly influenced by soil conditions and the availability of nutrients. Nutrients play a critical role in the growth and development of red chili plants. This experiment aimed to determine the combination of ameliorant, nutrient solution, and biofertilizer on the population of phosphate-solubilizing bacteria (PSB), available P, P-uptake, and red chili production in Inceptisols. The experiment was conducted at the experimental field of the Faculty of Agriculture, Universitas Padjadjaran. The experiment used a Randomized Complete Block Design (RCBD) with seven treatments and four replications, consisting of control, NPK, and nutrient solution (NS) with doses of 0, 6, and 12 kg ha-1 biofertilizers. The dosage used in a single application was 15 g plant-1 of NPK fertilizer and 300 mL plant-1 of nutrient solution. The base fertilizer consisted of manure in the control treatment and an ameliorant in other treatments at a dose of 4 t ha-1. The results showed that the combination of ameliorant + NPK + 6 kg ha-1 biofertilizer increased PSB population (4.93 x 106 CFU mL-1), available P (15.4 ppm), and P-uptake (0.74 g plant-1). Meanwhile, the combination of ameliorant + nutrient solution + 6 kg ha-1 biofertilizer increased fruit diameter (15 mm), and length of red chili (17.3 cm). Correlation analysis indicated positive correlation between red chili production with stem diameter and fruit length, but a negative correlation with P-uptake. Regression analysis indicated that stem diameter and PSB population had the most dominant effect on red chili yield. Produktivitas dan kualitas cabai merah sangat dipengaruhi oleh kondisi tanah dan ketersediaan unsur hara. Unsur hara memegang peranan penting dalam pertumbuhan dan perkembangan tanaman cabai merah. Percobaan ini bertujuan untuk mengetahui kombinasi amelioran, larutan hara dan biofertilizer terhadap populasi bakteri pelarut fosfat (BPF), P tersedia, serapan P, dan produksi cabai merah pada tanah Inceptisols. Percobaan dilaksanakan di lahan percobaan Fakultas Pertanian Universitas Padjadjaran. Percobaan menggunakan Rancangan Acak Kelompok Lengkap (RAKL) dengan tujuh perlakuan dan empat kali ulangan, terdiri dari: kontrol, NPK dan Larutan Hara dengan dosis 0, 6, dan 12 kg ha-1 pupuk hayati. Dosis yang digunakan dalam satu kali aplikasi adalah pupuk NPK 15 g tanaman-1 dan larutan hara 300 mL tanaman-1. Pupuk dasar berupa pupuk kandang pada perlakuan kontrol dan amelioran pada perlakuan lain dengan dosis 4 t ha-1. Hasil penelitian menunjukkan bahwa kombinasi amelioran + NPK + 6 kg ha-1 pupuk hayati mampu meningkatkan populasi BPF (4,93 x 106 CFU mL-1), P tersedia (15,4 ppm), dan serapan P (0,74 g tanaman-1). Sementara itu, kombinasi amelioran + larutan hara + 6 kg ha-1 pupuk hayati mampu meningkatkan diameter buah (15 mm), dan panjang cabai merah (17,3 cm). Analisis korelasi menunjukkan korelasi positif antara produksi cabai merah dengan diameter batang dan panjang buah, tetapi korelasi negatif dengan serapan P. Analisis regresi menunjukkan bahwa diameter batang dan populasi BPF memiliki pengaruh paling dominan terhadap hasil cabai merah.

Abstract

The consumption of red chili (Capsicum annum L.) increased annually, requiring higher productivity. However, this is not supported by optimal soil fertility which has a low nutrient content. This research aimed to examine the interaction between bioameliorant dose (B) and nutrient solution application interval (F) on phosphate solubilizing bacteria (PSB), available P, P uptake, fruit weight per plant, and fruit weight per fruit. The research was conducted using a Factorial Randomized Block Design with two factors and three replications (bioamelioran dosage: 0, 3, 6 t ha-1) and nutrient solution application interval: every one, three, and five days. The results showed an interaction effect on fruit weight with the best treatment being a bioameliorant dose of 3 t ha-1 and a nutrient solution interval once a day. The bioameliorant increased available P and the nutrient solution interval had influenced on soil available P and fruit weight per plant. Application of a bioameliorant dose of 3 t ha-1 and nutrient solution interval once a day produced the highest yield of chili.   ABSTRAK Konsumsi cabai merah (Capsicum annum L.) meningkat setiap tahunnya, sehingga membutuhkan produktivitas yang lebih tinggi. Namun, hal ini tidak didukung oleh kesuburan tanah yang optimal serta memiliki kandungan nutrisi yang rendah. Penelitian ini bertujuan untuk mengetahui interaksi antara dosis bioamelioran (B) dan interval pemberian larutan hara (F) terhadap bakteri pelarut fosfat (BPF), P-tersedia, serapan P, bobot buah per tanaman, dan bobot buah per buah. Penelitian dilakukan menggunakan Rancangan Acak Kelompok Faktorial dengan dua faktor dan tiga ulangan (dosis bioamelioran: 0, 3, 6 t ha-1) dan interval pemberian larutan hara: setiap satu, tiga, dan lima hari. Hasil penelitian menunjukkan adanya pengaruh interaksi terhadap rerata berat buah, dengan perlakuan terbaik adalah dosis bioamelioran 3 t ha-1 dan interval pemberian larutan hara satu kali sehari. Pemberian bioamelioran mampu meningkatkan P-tersedia. Interval pemberian larutan hara mempengaruhi kandungan P-tersedia tanah dan bobot buah per tanaman. Aplikasi bioamelioran dengan 3 t ha-1 dan interval pemberian larutan hara satu kali sehari menghasilkan hasil cabai merah tertinggi.   Kata kunci: Cabai Merah, Mikroba Menguntungkan, Pembenah Tanah, Unsur Hara
