<p>ABSTRAK<br />Penggunaan varietas jahe yang responsif terhadap pemupukan dosis<br />rendah, diharapkan mampu meningkatkan efisiensi pemupukan dan<br />menekan pencemaran lingkungan. Penelitian dengan tujuan untuk<br />mengetahui respon lima aksesi jahe putih kecil terhadap pemupukan dosis<br />rendah telah dilaksanakan di Kebun Percobaan Cimanggu pada bulan<br />Agustus 2009 sampai Mei 2010. Lima aksesi jahe putih kecil dari daerah<br />marginal ditanam dalam polibag dan disusun menggunakan rancangan<br />acak kelompok yang diulang 3 kali. Setiap perlakuan terdiri atas 20<br />tanaman. Dua perlakuan yang diuji secara faktorial adalah, faktor I adalah<br />5 aksesi jahe putih kecil, yaitu (1) Ziof 0004, (2) Ziof 0007, (3) Ziof 0008,<br />(4) Ziof 0013, dan (5) Ziof 0014, dan faktor II adalah dosis pupuk, yaitu<br />(a) 50% dosis anjuran (200 kg/ha urea + 150 kg/ha SP-36 + 150 kg/ha<br />KCl), (b) 75% dosis anjuran (300 kg/ha urea + 225 kg/ha SP-36 + 225<br />kg/ha KCl), dan (c) dosis anjuran (400 kg/ha urea + 300 kg/ha SP-36 +<br />300 kg/ha KCl). Masing-masing perlakuan diberi pupuk kandang sebagai<br />pupuk dasar dengan dosis 20 t/ha. Pengamatan dilakukan terhadap<br />parameter pertumbuhan (tinggi tanaman, jumlah anakan, diameter batang,<br />dan jumlah daun), hasil dan serapan unsur hara N, P, dan K pada umur 4<br />BST dan 9 BST. Hasil penelitian menunjukkan bahwa masing-masing<br />aksesi memberikan respon yang berbeda terhadap penurunan dosis pupuk,<br />baik pada fase pertumbuhan maupun produksi tanaman jahe. Pengurangan<br />dosis pupuk sampai 25% tidak mengurangi produksi jahe, tetapi penurunan<br />dosis pupuk sampai 50% dari dosis rekomendasi menyebabkan penurunan<br />produksi jahe secara nyata. Komposisi unsur hara N, P, dan K yang<br />diserap berbeda pada setiap fase pertumbuhan tanaman.<br />Kata kunci : Aksesi, Zingiber officinale, pemupukan, pertumbuhan,<br />produksi</p><p>ABSTRACT<br />Response of five accessions of small white ginger to<br />fertilizers<br />The use of ginger varieties responsive to low fertilization dosages,<br />is expected to increase fertilizer use efficiency and reduce environmental<br />pollution. Research aimed at observing response of five small white ginger<br />accessions of low-dosage fertilization has been conducted in the Cimanggu<br />Experimental Station in from August 2009 through May 2010. Five small<br />white ginger accessions from marginal areas were planted in polybags.<br />The experiment was and arranged using a randomized block design was<br />repeated with 3 times replications. Each treatment consisted of 20 plants.<br />Two treatments were tested factorially, where factor I : 5 small white<br />ginger accessions, namely (1) Ziof 0004, (2) Ziof 0007, (3) Ziof 0008, (4)<br />Ziof 0013, and (5) Ziof 0014, and factor II : 3 fertilization dosages is<br />dosage of fertilizer, namely (a) 50% recommendation dosage (200 kg urea<br />+ 150 kg SP-36 + 150 kg KCl per hectare), (b) 75% recommendation<br />dosage (300 kg urea + 225 kg SP-36 + 225 kg KCl per hectare), and (c)<br />recommendation dosage (400 kg Urea + 300 kg SP-36 + 300 kg KCl per<br />hectare). Each treatment was given 20 t/ha of manure as basal fertilizer.<br />The parameters observed were growth parameters (plant height, number of<br />tillers, stem diameter, and number of leaves), yield and nutrient uptake of<br />N, P, and K at 4 and 9 months after planting (MAP). The results showed<br />that each of the accessions responded differently to the reduction of<br />fertilizer dosages, either in vegetative or generative growth phase of ginger<br />plants. Reduction of fertilizer dosages to 25% did not significantly reduce<br />the yield of ginger, however, fertilizer dosages reduction up to 50% of the<br />recommended dosages led to significant decrease of ginger yield.<br />Compositions of N, P, and K nutrients absorbed by plants were different in<br />every phase of plant growth.<br />Keywords : Accessions, Zingiber officinale, fertilizer, growth, yield</p>

The use of Efficient Microorganisms (EM) can be an effective alternative to improve plant growth and yield in the bean cultivation. Therefore, different forms of application of efficient microorganisms were evaluated in the production of two cultivars of the common bean from November of 2013 to March of 2014. Two factors were studied; the first one was comprised of the two cultivars, Velazco Largo (VL) and Cuba Cueto (CC-25-9-N). The second factor consisted of four treatments with EM; without EM (control), soil inoculation (100 mL L-1), foliage applications (100 mL L-1), and the combined soil inoculation (100 mL L-1) plus foliar applications (100 mL L-1). The experiment was carried out in a randomized block design, in factorial outline 2×4, with three repetitions. The agronomic indicators were evaluated as the number of leaves per plant, the height of plants, number of pods per plant, number of seeds per pod, the mass of 100 seeds (g) and the yield (t ha-1). The results showed that the different forms of application of efficient microorganisms stimulated the agronomic indicators evaluated in both crops. The associated applications between the inoculation of the soil and foliage applications of efficient microorganisms provided better results, producing increments in the yield of 1.13 t ha-1 in VL and 2.15 t ha-1 in CC-25-9-N.

Papaya is a very popular fruit in the tropical and subtropical regions of the world and has witnessed an increase in demand. This has fuelled an interest to develop region specific hybrids with desirable vegetative growth and vigour.  Hence a field experiment was carried out at College of horticulture and forestry, Navsari Agricultural University in Gujarat during 2018-2020 in randomized block design with three replications to know the mean performance of parents and hybrids for comparative growth performances of papaya. Wherein, thirty papaya hybrids were developed from six morphologically distinct parents through full diallel crossing technique and all the parents and hybrids were evaluated for their germination and growth parameters. The variability was distinct in all hybrids and parents for germination percentage, days taken to germination, periodical plant height and girth, number of leaves, petiole length and internodal distance. Amongst all the parents, Pusa Delicious, CO-8 and Lucknow Local exhibited improved germination, better vegetative growth and dwarf stature, respectively. Among the hybrids, Pusa Delicious x Lucknow Local was found to have dwarf stature with minimum internodal length however, the reciprocal cross: Lucknow Local x Pusa Delicious recorded maximum plant girth and number of leaves. Based on their mean performance, these parents can be used for further breeding programmes and hybrids could be exploited for cultivation.

Cassava is one of the local food sources that are widely available in almost every region. Cuttings are used to plant cassava, and these cuttings will produce a number of roots and buds. The main purpose of this study was to evaluate the effect of cuttings slices model and the number of buds on the growth of Tobelo local varieties of cassava. This study employed a factorial Randomized Block Design (RBD), with the cuttings slices model as the first factor, consisting of three levels, namely: flat slice, one-sided slice and two-sided slice. The second factor is the number of buds, which is divided into three levels, 1 bud, 2 buds and 3 buds. The observation parameters in this study include plant height, number of leaves, stem diameter and leaf area. The results have revealed that the model of two-sided sliced cuttings combined with the number of one bud is the most effective treatment in improving the growth of cassava plants of Tobelo local varieties. The models of one-sided and two-sided oblique cuttings slices yield the highest average value for the parameters of plant height, stem diameter and leaf area, while the treatment with one bud tends to give the best results for the growth parameters.

Soybean is one of the secondary crops that has a good economic value. Soybean needs are increasing with increasing population, but production is not sufficient. Extensification programs can be carried out in sub-optimal swamp swamps with water saturated cultivation technology. Low pH and high Al and Fe are the main obstacles. One of the strategies taken is the provision of coral ameliorants. The aim of this study was to obtain information on the effectiveness of coral reefs to improve the cultivation of black soybean in swamp swamps. The study was conducted in March - May 2018 at the Experimental Garden of the Faculty of Agriculture, University of Ratu Samban Arga Makmur Bengkulu Utara. The study used a randomized block design with factorial patterns. The first factor in the dose of ameliorant per plant consisted of: P0: control, P1= 5 g, P2 = 6 g, P3= 7 g, P4= 8 g, P5= 9 g, P6= 10 g. The second factor when the ameliorant application consists of: W1= 4 weeks before planting (MBT), W2 = 3 MBT, W3 = 2 MBT, W4 = 1 MBT, W5= when planting, W6= 1 weeks after panting. The results showed that the treatment of the dose and time of application of coral ameliorants had a very significant effect on plant height and number of leaves. There is no real interaction between the dose and time of ameliorant application to all variables.
