      Abstract
      Produktivitas jagung dipengaruhi oleh faktor meteorologi dan ketersediaan air tanah yang berbeda pada setiap wilayah. Provinsi Jawa Timur dan Nusa Tenggara Timur memiliki karakteristik iklim yang berbeda sehingga berpotensi menghasilkan respons produktivitas jagung yang berbeda. Penelitian ini bertujuan mendeskripsikan karakteristik radiasi matahari, curah hujan, suhu udara, dan kelembapan tanah zona perakaran serta menganalisis pengaruh langsung dan tidak langsung faktor meteorologi terhadap produktivitas jagung di kedua wilayah tersebut. Data yang digunakan meliputi produktivitas jagung, radiasi matahari, curah hujan, suhu udara, dan kelembapan tanah zona perakaran periode 1985–2024. Analisis dilakukan menggunakan regresi linier berganda dengan koreksi Newey–West dan path analysis. Hasil penelitian menunjukkan bahwa suhu udara dan kelembapan tanah zona perakaran berpengaruh positif dan signifikan terhadap produktivitas jagung pada kedua wilayah penelitian. Curah hujan berpengaruh signifikan terhadap produktivitas jagung di Nusa Tenggara Timur, sedangkan radiasi matahari tidak menunjukkan pengaruh langsung yang signifikan pada kedua wilayah. Hasil path analysis menunjukkan bahwa kelembapan tanah zona perakaran berperan sebagai variabel mediasi utama yang menghubungkan faktor meteorologi dengan produktivitas jagung, terutama pada wilayah semi-arid seperti Nusa Tenggara Timur.
       
      Corn productivity is influenced by meteorological factors and groundwater availability, which vary by region. East Java and East Nusa Tenggara provinces have distinct climatic characteristics, which may result in different corn productivity responses. This study aims to describe the characteristics of solar radiation, rainfall, air temperature, and soil moisture in the root zone, as well as to analyze the direct and indirect effects of meteorological factors on corn productivity in both regions. The data used include corn productivity, solar radiation, rainfall, air temperature, and soil moisture in the root zone for the period 1985–2024. The analysis was conducted using multiple linier regression with Newey–West correction and path analysis. The results indicate that air temperature and soil moisture in the root zone have a positive and significant effect on corn productivity in both study regions. Rainfall significantly affects corn productivity in East Nusa Tenggara, while solar radiation does not show a significant direct effect in either region. The results of the path analysis indicate that soil moisture in the root zone acts as the primary mediating variable linking meteorological factors to maize productivity, particularly in semi-arid regions such as East Nusa Tenggara.
