Abstract

This study aimed to determine the effect of single dose of inorganic fertilizer N,P,K and the type of biological fertilizer on the growth and yield of sweet corn (Zea mays subsp. mays L.). The study was arranged in a randomized block design (RBD) with two factors. The first factor was the dose of single inorganic fertilizer N,P,K, which consisted of 3 levels: D1: 100%, D2: 75%, and D3: 50%. The second factor is the type of biological fertilizer, which consisted of 3 levels: P1: Sinarbio, P2: Kayabio, and P3: Ecofert. The results showed that the application of a single inorganic fertilizer N,P,K at a dose of 75% had a significant effect on the parameters of plant height, number of leaves, stem diameter, number of cobs planted, cob weight with cornhusk, cob weight without cornhusk, and yield potential. The type of biofertilizer Sinarbio has a significant effect on the parameters of plant height, number of leaves, stem diameter, number of cobs planted, number of cobs per plot, cob weight with cornhusk, cob weight without cornhusk, and yield potential. The use of a single dose of inorganic fertilizer N,P,K can be reduced to a dose of 75% of the recommendation for sweet corn plants with the application of biofertilizer Sinarbio.

Abstract

Methane emissions from the agricultural sector represent a critical challenge for global climate change mitigation. This study aims to map the patterns, trends, and development of research on methane emission reduction in the agricultural sector through the implementation of Alternate Wetting and Drying (AWD) using a bibliometric approach. Scientific publication data were collected from Scopus and analyzed following the PRISMA method, resulting in 325 relevant articles for analysis using VOSviewer. The results reveal a significant increase in publications, particularly after 2021, and identify five main thematic clusters ranging from biophysical responses to environmental quality. Temporal analysis indicates a shift in research focus from biophysical approaches toward the integration of climate mitigation, resource-use efficiency, and sustainable agricultural systems. This study concludes that AWD is an effective mitigation strategy with strong potential to reduce methane emissions without compromising rice productivity. Ultimately, these findings underscore the necessity of integrating AWD into future sustainable agricultural policies and climate mitigation actions to advance low-carbon food production globally. Keywords: Alternate wetting and drying, bibliometric analysis, low-carbon agriculture, methane emission reduction, sustainable agriculture
