Abstract

Maize crops experiencing water stress can experience cell damage, loss of turgor, closed stomata, plant leaf roll then wilt.  Germination and vegetative growth are thought to be a very sensitive phases in relation to the availability of water, because it can influence subsequent growth processes. This study aimed to determine the potential tolerance of Southeast Sulawesi’s maize genotypes to drought stress at different vegetative growth phases. This study was based on completely randomized design (CRD) with factorial pattern consisting of two factors: the first factor composed of 9 local maize genotypes of Southeast Sulawesi and 1 national variety (cv. Arjuna), while the second factor was drought stress at different vegetative growth phases, consisting of four levels ie:  C0 = plants irrigated with 100 % water availability during the growth phase, C1 = Stress for 5 days , at 21-26 days old (vegetative phase), C2 = Stress for 5 days starting at panicle emergence (early flowering stage), and C3 = Stress for 5 days starting 2 weeks after silking.  Research results showed that Genotype (G) treatment significantly influenced all observed growth variables (at age 21 and 42 days after planting, DAP), except for the variable of number of leaf, age 21 DAP. However, water stress treatment (C) only significantly affected plant height variable, at the age of 42 DAP.   In general, G6 and G7 genotypes tended to have a higher crop and trunk diameter than the other genotypes.  Contrary, G3 genotype tended to have shorter crop and smaller stem diameter than the other genotypes.  There are indications that the drought stress treatment (C) significantly inhibited the growth of maize crops. Keywords: drought strees, maize genotypes, tolerance, and vegetative phases

Abstract

The experiment was conducted in the Rahandouna village, Poasia, Kendari Southeast Sulawesi, from August to November 2013.  The purpose of this study was to determine the estimate of heritability between characters of thirteen local waxy corn cultivars of Southeast Sulawesi. This study was prepared using a randomized block design (RBD), with 3 replicates. Total waxy corn cultivars studied was 13 species, so that there were 39 plots. Each plot consisted of a single cultivar. Observed variables were plant height (cm), stem diameter (cm), leaf area (cm2), number of leaves (strands), ear length (cm), cob diameter (cm), number of rows per ear, weight of 100 seeds (g), ear weight. The results of this study showed that there was narrow variability on all local waxy corn characters observed. Keywords: Local waxy corn, characters, cultivars, Southeast Sulawesi, variability

Abstract

Buah tomat (Lycopersicum esculentum Mill.) merupakan salah satu produk pangan penting, selain itu tomat merupakan bahan baku industry dan kosmetika bahkan sebagai bahan obat-obatan, namun produksinya masih fluktuatif dari tahun ke tahun karena umumnya dibudidayakan pada tanah marjinal. Tujuan penelitian ini adalah untuk mengetahui pengaruh pupuk kandang kambing dan bokasi limbah pasar terhadap pertumbuhan dan hasil tomat pada tanah Ultisol. Penelitian menggunakan Rancangan Acak Kelompok pola factorial, dengan 3 ulangan. Faktor pertama adalah pupuk kandang kambing (K) yang terdiri dari 4 taraf yakni: K0= tanpa perlakuan, K1= 300 g polybag-1, K2= 400 g polybag-1, K3= 500 g polybag-1. Faktor kedua adalah bokasi limbah pasar (P) yang terdiri dari 4 taraf yaitu P0= tanpa perlakuan, P1= 300 g polybag-1, P2= 400 g polybag-1, P3= 500 g polybag-1. Hasil penelitian menujukkan bahwa penggunaan pupuk kandang kambing dan bokasi limbah pasar secara nyata meningkatkan tinggi tanaman, jumlah daun, jumlah buah dan bobot buah per tanaman. Aplikasi 500 g pupuk kandang kambing dan 500 g bokasi limbah pasar masing-masing mencatatkan bobot buah terberat yakni 242,12 g dan 197,27 g per tanaman.
