Abstract

Saat ini faktor iklim yang semakin tidak menentu mengakibatkan berkurannya ketersediaan air yang berdampak negatif bagi pertumbuhan tanaman. Penelitian ini dilakukan untuk mengetahui pengaruh dosis pupuk KCl dan berbagai kadar air media tanah dipembibitan kelapa sawit. Penelitian ini dilaksanakan di Desa Sumbersari, Kecamatan Sumbersari, Kabupaten Jember, Jawa Timur mulai April hingga September 2021 menggunakan rancangan acak kelompok faktorial. Percobaan dilakukan untuk meneliti pengaruh dosis KCl dan kadar air media terhadap pertumbuhan bibit kelapa sawit, dosis pupuk KCl terdiri dari 4 level yaitu 0 g, 0,4 g, 0,6 g dan 0,8 g setiap tanaman, kadar air media tanah terdiri dari 3 level yaitu 100%, 70% dan 50% dari kapasitas lapang dengan 3 ulangan. Hasil penelitian diketahui bahwa perlakuan interaksi dua faktor antara kadar air media dan dosis KCl didapatkan hasil tidak berbeda nyata, demikian juga faktor tunggal dosis KCl tidak berbeda nyata, sedangkan faktor tunggal kadar air media menunjukkan pengaruh berbeda nyata. Level perlakuan kadar air 70% didapatkan hasil berbeda nyata pada parameter tinggi tanaman sebesar 18,44 cm, parameter jumlah daun sebesar 3,67 helai, parameter diameter bonggol sebesar 5,63 mm dan leaf area index sebesar 1,72. Hasil analisis lebar pori stomata (μm) pada berbagai kondisi kadar air media menunjukkan nilai rata-rata tertinggi pada kadar air media 70% sebesar 11,88 ± 4,96 dan pada berbagai dosis KCl menunjukkan nilai rata-rata tertinggi pada dosis KCl 0,6 g sebesar 10,83 ± 7,90.

Abstract

Water management is very important for plants and good water management can increase the productivity of rice, corn and soybeans, hereinafter referred to as PAJALE. This paper aims to estimate the water requirements of PAJALE plants using the cropwatt model. The results of the analysis show that each plant has different water requirements in each growth phase which was analyzed using cropwatt application throughout the year with medium textured soil types. Rice, corn and soybeans are the main food commodities in Indonesia. Corn and soybeans are generally planted after rice in irrigated and rainfed rice fields, making them susceptible to drought. Therefore, information using cropwatt applications, especially rainfall, temperature, Air humidity and solar radiation are very important in determining the time of planting and the right water requirements for plants. The purpose of the study was to determine the planting time and water requirements of rice, corn and soybeans, based on the results of cropwatt 8.0 analysis, and to compile a time map of Indonesian food crops so that the risk of production failure due to drought can be avoided.
