Abstract

Abstrak.Tanamanpadi (Oryza sativa L.) adalah tanaman pangan pokok terpenting dengan kebutuhan setiap tahun yang meningkat, sehingga perlu dilakukan instensifikasi agar dapat meningkatkan produksi tanpa mengakibatkan degradasi lahan akibat aplikasi pupuk anorganik terus menerus. Penelitian ini dilaksanakan di areal sawah petani, wilayah Kutai Kartenegara, dengan jenis tanah ultisol. Tujuan dari penelitian ini adalah 1. Mengetahui dosis optimum pupuk NPK Phonska, 2. Mengetahui pengaruh Zat Pengatur Tumbuh (ZPT) Ratu Biogen dan dosis optimum terhadap pertumbuhan dan produksi padi. Rancangan yang digunakan adalah Rancangan Acak Kelompok (RAK) dengan perlakuan 2 faktor dan 3 kali ulangan. Faktor I yaitu pupuk NPK Phonska dengan perlakuan P0, P1, P2 dan P3 (0 kg ha-1, 100 kg ha-1, 200 kg ha-1, dan 300 kg ha-1) dan Faktor II yaitu ZPT Ratu Biogen dengan perlakuan Z1, Z2 dan Z3 (0 ml ha-1, 1500 ml ha-1, dan 3000 ml ha-1). Data analisis pengamatan adalah data tanah , data parameter tanaman dan data analisis jaringan tanaman. Hasil penelitian ini menunjukan bahwa perlakuan pupuk NPK Phonska dan ZPT Ratu Biogen berpengaruh sangat nyata terhadap pertumbuhan vegetative dan pemupukan NPK Phonska dengan dosis yang diamati bersifat linier dengan persamaan Yz1= 4173,5 + 3,46 x dan koefisien korelasinya r1 = 0,9931. Persamaan Yz2=4629,8 + 4,9567 x dan koefisien korelasinya r2 = 0,9352, selanjutnya persamaan Yz3=4733 + 6,8383 x, koefisien korelasinya r3 = 0,9409. Dosis pupuk 300 kg ha-1menghasilkan gabah kering 6183,89 kg ha-1 (6,18 ton ha-1) serta, pemberian ZPT Ratu Biogen meningkatkan pertumbuhan dan produksi tanaman padi. Dosis terbaik 3000 ml ZPT/hektar

Abstract

The purpose of this study to determine the effect of fertilization on the production of three varieties of cassava that is Darul Hidayah, Gajah and Varietas Local. The field experiment was conducted for 9 months starting from April to December 2016. Locations trial in Sangata Selatan, DistrictKutai Timur.The design is split plot design arranged in a factorial treatment was repeated 3 times (R) Treatment Varieties (V) as the main plots and fertilizer treatments (P) as subplot. The results showed that the inorganik  fertilizer (NPK), organik  (Bokashi) and combinations thereof capable of producing tubers each, 124 tons per hectares, 130.44 tons per hectares, and 134.67 tons per hectares and 99.11 ton per hectares as a kontrol s. Fertilization treatment of three varieties cassava tubers can increase production 20%. 23.8% and 26% respectively as a compared with kontrol s. While the tuber production between varieties Darul Hidayah and Gajah 148.50 tons perhectares and 132, 33 ton per hectares while the local variety 85.33 tons per hectares. The increase in the tubers from 3 varieties namely 42.5% and 35.6% compared to local varieties. Keywords: anorganik  and organik  fertilizers, varieties of cassava

Abstract

The purpose of this study was to  determine  optimum water requirement of eggplant (Solanummelongena  L) onsandy clay loam soil of Ultisols during  it growth period. The experiment was conducted on 5th May to 27thAgust2017  in glass house Faculty of Agiculture, Mulawarman University, Samarinda. The pot experiment was designed Completely Randomized Design  that consisted of four treatments  level with seven replications. Treatment  based  on  water avaibility (WA), those are  :  A = 494 ml  (50 % WA),   B = 670 ml  (75 % of  WA) C = 846 ml ( 100 %  of WA)  and  D =   1022 ml (  125 % of WA).Each  experiment  pot contained   10 kg  dried  soil.  The  treated  pots(after watering)   have  weight  respectively,   A=  10494  g,  B =  10670  g,  C= 10846 g, and   D= 11022 g. These  pots will be  weighted  every  daycontinouslyduring plant  growth and  maintained   those pot  weight  respectively.Vegetative  and  generative data  were collected  and  statistical analyzed using variance analysis. If the treatments showed significant different  effect, the statistical analysis of those treatment continued by Least Significant Different (LSD) test at 5% level to find out the  optimum water requirement level. The results of the experiment showed that  treatments of watering  was significant   effect on the average of vegetative  parameters, (vegetative  growth i.e.plant height at the age 20, 40, and 60 days,  blooming after planting.) and  significant  effect for generative parameters (fruit number, length and  fruit weight).The optimum  water requirement   for  eggplant at  506 ml pot-1  therefore during growth period  eggplant   needs   40,731 ml of waterfor  maximum yield.

Abstract

This research was a solution to free desease banana kepok yellow which was decrease the banana product in East Kalimantan. This research were devided three years and it would be continued. The first years seedling propagation free desease through tissue culture. The second years the seedling derived tissue culture which was planted on the field, until harvesting fruit product. The third years processing fruit product to several kind of industrial product. The aim of the first years research was the highest number shoot regenerated from the explant center of banana corm, which induction several combination treatment of plant growth regulator Benzyl Amino Purine (BAP) and Indole Butyric Acid (IBA). This research conducted at Tissue Culture Laboratory of Agriculture Faculty of Mulawarman University, from March until November 2015. This research was used Randomized Completely Block Design with two factors. The firest factor : BAP consist 3 level consentration were : 2,5; 5 and 10 ppm and the secon factor : IBA consist 3 level consentration were : 0; 1 and 2 ppm. So that all of combination of plant growth  regulator were 9 treatments. Each treatments were replicated ten times. Result of this research showed that all combination of concentration treatment of plant growth regulator BAP and IBA could be induce the growth and differentiation of explant center of banana corm in Murashige and Skoog (MS) media, like : inbibition, developed tissue of explant, callusing and shooting, although the percentage and totality was variation. The colour of callus was yellow and light green. While the structure was hard and compact. The highest average number of shoots induction at VII combination treatments BAP 10 ppm + IBA 0 ppm ware 3.80± 1,76 shoots/explant which was the root un completely development. So that it need sub culture to the rooting induction media with IBA 10 ppm to be formed completely plantlet (seedling), which could be survived on acclimatization processing.
