Budidaya tanaman tomat di lahan pasir pantai seringkali terhambat akibat salinitas udara. Pengaruh negatif salinitas udara dapat diminimalisir dengan cara pencucian garam menggunakan air. Tujuan dari penelitian ini yaitu, mengetahui pengaruh salinitas udara terhadap fisiologi dan hasil pertumbuhan tanaman tomat, mengetahui pengaruh jeda waktu penyemprotan air terhadap fisiologi dan hasil pertumbuhan tanaman tomat, dan mengetahui interaksi antara pengaruh salinitas udara dan jeda waktu penyemprotan air terhadap fisiologi dan hasil pertumbuhan tanaman tomat. Penelitian ini menggunakan rancangan lingkungan Rancangan Acak Kelompok Lengkap (RAKL) yang terdiri dari faktor pertama salinitas udara (S), meliputi 0, 12, 24 mS/cm dan faktor kedua jeda waktu penyemprotan air (L), meliputi 0, 45, 90 menit. Data pengamatan dianalisis menggunakan ANOVA dan dilanjutkan dengan uji lanjutan DMRT, serta analisis Regresi. Hasil penelitian menunjukkan bahwa salinitas udara memberikan pengaruh signifikan terhadap kadar prolin vegetatif dan kerapatan stomata generatif, sedangkan perlakuan jeda waktu penyemprotan air pada variabel bobot segar daun dan bobot segar buah. Dua perlakuan tersebut menghasilkan interaksi yang sangat signifikan pada bukaan stomata vegetatif.

Tomato cultivation on coastal sandy soils is often hindered by air salinity. The negative effects of this air salinity can be reduced through salt leaching using water. The objectives of this study were to determine the effect of air salinity on the physiology and growth yield of tomato plants, to determine the effect of the water application delay on the physiology and growth yield of tomato plants, and to determine the interaction between the effects of air salinity and the water application delay on the physiology and growth yield of tomato plants. This study used a Completely Randomized Block Design (CRBD) consisting of two factors: the first factor is air salinity (S), which includes 0, 12, and 24 mS/cm; and the second factor is water application delay (L), which includes 0, 45, and 90 minutes. The experimental data were analyzed using ANOVA, followed by the Duncan Multiple Range Test (DMRT), as well as regression analysis. The results showed that air salinity had a significant effect on the vegetative proline content and generative stomatal density. Meanwhile, water application delay significantly affected the variables of fresh leaf weight and fresh fruit weight. These two treatments showed a highly significant interaction on vegetative stomatal aperture.
