This study explores bibliometric analysis of advanced breeding tools for drought-tolerant maize, focusing on transgenic, marker-assisted selection (MAS), high-throughput phenotyping (HTPP), and genome editing. The research underlines the growing importance of these tools in developing drought-tolerant maize varieties to address climate change issues. The methodology involves identifying countries significant in advanced breeding research, analyzing common terms in publications, and examining networking where authors share their work. The dataset from Scopus was divided into two categories: a unified query and segmented queries, categorizing documents into four specific themes: transgenic, MAS, HTPP, and genome editing. A careful filtering process removed duplicates and irrelevant documents, ensuring dataset accuracy and relevance. Results reveal varying emphasis on different advanced breeding tools, with transgenic techniques leading at 51.30 %, followed by MAS at 19.87 %, HTPP at 19.74 %, and genome editing at 9.04 %. Co-occurrence analysis highlights distinct associations for each tool: transgenic techniques are linked to specific gene modifications, transcriptional regulation, and genetic transformation; MAS is linked to quantitative trait loci (QTL) mapping, molecular markers, and Simple Sequence Repeat (SSR); HTPP is linked to remote sensing, multi/hyperspectral, crop phenology, and phenotypic traits; and genome editing is associated with CRISPR-Cas9 and complex trait loci. Integrating cutting-edge breeding tools such as HTPP and genome editing/CRISPR-Cas9 indicates a shift toward improving breeding efficiency and accuracy. Future research aims to refine precision editing techniques and promote transparent communication for ethical deployment. Collaborative efforts among research institutions and regulatory bodies for establishing standardized protocols and addressing safety, ethical, and environmental concerns, advancing the development of drought-tolerant maize varieties, and fortifying global food security amidst climate change.

The present study was initiated to determine whether isolates from soil and roots of paddy plants can affect the paddy plant’s growth and productivity. The study was conducted to answer the question, “Can paddy rice be grown when the NPK doze is reduced?” This study aims to apply the methanotroph bacteria on the growth and production of lowland rice. The research field was carried out in the rice fields of Amparita Village, TelluLimpoe District, Sidenreng Rappang Regency, South Sulawesi. This research was conducted from June to September 2020. The plants were arranged in a split plot Randomized Complete Block Design (RCBD), the main plot, namely, the NPK fertilizer dosage treatment (P) with 4 treatments, namely, without NPK fertilizer, 75 g/plot, 150 g/plot, and 360 g/plot. The subplots were methanotroph bacteria application with 4 treatments, namely: without bacteria, 106 CFU per ml of methanotroph, 107 CFU per ml of methanotroph, and 108 CFU per ml of methanotroph. The results showed that there was an interaction between the NPK fertilizer and methanotrophic bacteria. The best results were obtained on the combination of 360 g per plot of NPK fertilizer and methanotrophic bacteria with 106 CFU per ml on the observation of plant height (111.17 cm), and the combination of NPK fertilizer 0 g per plot and methanotrophic bacteria with 0 CFU per ml on the observation of fresh weight of grain was the highest (70.44 g), whereas the combination of NPK fertilizer treatment 360 g/plot and bacteria methanotroph 0 CFU per ml on the observation of dry weight of grain was 43.89 g. NPK fertilizer 360 g/plot and bacteria methanotroph 106 CFU per ml at an observation weight of 100 grains was the highest number (3.53 g).
