Abstract

Soil Conditioner & Growth Booster (SCGB) is a potion that was made to be used as a soil conditioner and plant growth promoter. SCGB is made from organic matter, biological fertilizers, soil ameliorants, and microelements. This research aims to determine the best dosage of SCGB on the agronomic characters, effective nodules, and black soybean variety ‘Detam-1’ yield. This research was conducted in the experimental field of the Faculty of Agriculture, Winaya Mukti University, Sumedang, Indonesia. This experiment used a simple randomized block design (RBD) with six treatments (0, 3, 6, 9, 12, 15 kg/ha) and repeated 4 times. The observation was conducted on a number of effective root nodules, plant height, number of leaves, 100-grain weight, number of pods, seed weight per plant, and seed weight per plot. The result showed that SCGB application significantly improved agronomic characteristics of black soybean plants, increasing the number of effective nodules by 147% to 168% compared to untreated plants. A dose of 3 kg/ha SCGB showed the best results in increasing 35% on yield seed weight per hectare compared to without application of SCGB.

Abstract

Background: In Indonesia itself, it is estimated that red chilies were brought by traders from Persia when they stopped in Aceh, including large red chilies, cayenne peppers, curly red chilies, and paprika. Factors that influence chili cultivation are less fertile soil conditions due to continuous use, this causes a decrease in soil quality which will affect the growth and production of chili plants and have an impact on reducing the growth and yield of chili production both in terms of quantity and quality, in addition to the use of quality seeds and superior varieties determine the increase in chili productivity. Methods: This research was conducted out from May 2022 to September 2022 in the experimental farm of the Faculty of Agriculture, Padjadjaran University, Jatinangor, Sumedang. With an altitude of about 700 meters above sea level (masl). The purpose of this research is to study the effect of volume combination and technique of nutrient solution administration on growth and yield of large red chilies (Capsicum annum L.) variety Baja F1. Providing nutrient solutions on time is intended to be according to the age of the plant, the right volume is intended to provide nutrient solutions with a certain volume that suits the needs of each plant, while right on target is intended to provide nutrient solutions in the root area or sprayed on the leaves, either fertilizing directly to the land or plant roots or spraying directly on the leaves (foliar feeding). The environmental design uses a simple pattern randomized block design (RAK) volume combination and technique of nutrient solution, with 6 experimental levels (A=volume 225 ml onto the field and without spraying onto the leaves, B=volume 300 ml onto the field and without spraying onto the leaves, C=volume 375 ml onto the field and without spraying onto the leaves, D=volume 200 ml onto the field and spraying onto the leaves, E=volume 300 ml onto the field and spraying onto the leaves and F=volume 375 ml onto the field and spraying onto the leaves), and repeated 4 times. Findings: The application of different combinations of nutrient solution volume and administration techniques significantly affected several growth parameters (such as plant height at 3 WAP, number of leaves at 1, 2, 4, and 5 WAP, and stem diameter at 4 and 5 WAP) as well as yield parameters (including number of chilies and total fruit weight). Conclusion: Among the treatments, the combination of applying 225 ml nutrient solution directly to the field along with foliar spraying produced the most optimal results in terms of both growth and yield of Baja F1 chili plants. Novelty/Originality of this article: This study provides novel insights into the integrated approach of combining precise nutrient volume and foliar feeding techniques, specifically identifying the synergistic effect of 225 ml root application and foliar spraying in enhancing growth and yield, which has not been thoroughly explored in previous chili cultivation studies.

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

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

Dampak dari intensifikasi pertanian tanpa memperhatikan kelestarian lahan pertanian sehingga lahan menjadi tidak produktif, padahal kebutuhan pangan semakin lama semakin meningkat. Artikel ini bertujuan untuk mengungkapkan kemampuan dari rekayasa mikrobioma rizosfer dalam meningkatkan kesehatan tanah dan produktivitas tanaman pangan serta mengetahui hambatan dan peluang dari mikrobioma rizosfer dalam mendukung pertanian berkelanjutan. Metode penelitian yang digunakan adalah Narrative Literature Review. Rekayasa mikrobioma rizosfer dapat meningkatkan populasi mikroba menguntungkan dengan mengurangi input kimia, tetapi tetap efektif dalam meningkatkan produktivitas tanaman pangan dan kesehatan tanah serta berperan dalam mendukung pertanian berkelanjutan. Penggunaan pupuk dan pestisida harus diatur dengan bijak agar tidak merusak mikrobioma rizosfer dan nutrisi tanah tetap terjaga.
