Abstract

Activity was conducted in July until October 2009. Research prepared on randomized block design, three replications. Purpose: to know respons of three maize varieties which cultivated on dry land. Size of plots area is 15 m × 16 m, plant spacing 75 cm × 40 cm, two plants per hole. Varieties assess is Bima-3 Bantimurung, Srikandi Kuning, and Bisi-2. Dosage of fertilizer used is NPK Phonska 300 kg, urea 300 kg, chicken manure two t ha-1. Study shows: varieties Bima-3 Bantimurung, Srikandi Kuning give highest growth and yield than Bisi-2. Phonska NPK fertilizer application combined with manure give average yield of maize is higher than average of national and Moluccas yields, each 3.45 t ha-1 and 2.30 t ha-1, respectively. Bima-3 Bantimurung hybrid variety gives average highest yield and not significantly different from composite Srikandi Kuning, but significantly different from hybrid Bisi-2. Bima-3 Bantimurung and Srikandi Kuning potentially developed on dry land in Moluccas because in addition to high yield, Bima 3 Bantimurung a maize hybrid that has a high biomass and stay green until harvest so that waste can be utilized for animal feed, while Srikandi Kuning is a composite maize rich of protein that can be used as an alternative food sources. Key-words: growth, variety, maize.

Abstract

Kajian pemupukan tomat di lahan petani bekas sawah selama tiga tahun.  Luas areal 50 ha untuk hortikultura, termasuk tomat. Tujuan: melihat pertumbuhan dan hasil tomat dataran rendah diberi pupuk organik dan anorganik. Rancangan Faktorial RAK dua faktor, yaitu pupuk organik: pupuk cair, pupuk kandang, pupuk organik.  Faktor kedua: pupuk anorganik: (1) PA-1: urea 150 kg per ha, SP-36 200 kg per ha, dan KCl 100 kg per ha, (2) PA-2: NPK Pelangi 500 kg per ha+urea 100 kg per ha, (3) PA-3: Setengah dosis PA-1, dan (4) PA-4: Setengah dosis PA-2. Tiap perlakuan diulang tiga kali.  Varietas: Tombatu F1 jarak 50 cm x 60 cm.  Hasil: tertinggi pada perlakuan pupuk anorganik tunggal, pupuk organik cair, dan kombinasinya. Selain itu juga memberikan hasil lebih tinggi dibanding pupuk organik granul atau kombinasinya. Pupuk organik cair berprospek cukup baik karena memberikan hasil tinggi dibanding kandang atau organik granul, terutama bila dikombinasi dengan pupuk anorganik tunggal. Lahan hortikultura Desa Waihatu perlu rotasi atau diberokan untuk memulihkan kondisi lahan yang terus menerus ditanami.
