Abstract

Several years ago at 2000 Kepok “Yellow” Banana plantation  in East Kalimantan was attached disease, so that the production was decrease therefor in vitro propogation was a preferred a n alternative method. The aim of this study was to knew the growth and disease resistance of Kepok “Yellow” Banana post acclimatization seedling in nursery giving trichoderma as a biological control technique. This study was conducted in April until July 2018 in Samarinda. The completely randomized factorial was used as experiemental design with two factor ie: giving trichoderma (T) consist two level : with trichoderma (T1) and without trichoderma (T0), another factor ie : giving Nasa liquid organic fertilizer (N), consist four level : N0  (0 ml/l water); N1 (2 ml/l water); N2 (4 ml/l water); N3 (6 ml/l water). So that became 8 treatments, each treatment were repeated for five times.The total population were 40 polybags. Each polybags was planted 1 seedling after post acclimatization  healthy and  strong.  The  parameter  observed    were  increase  of  plant  hight, number of leaves, length of the longest leaves, width of the widest of leaves and diameter of stem. Observation the parameter was every two weeks, except diameter of stem, wich was only the end of observation. Polybag was filled with a mixture of   top soil and goat manure with ratio 4:1. Trichoderma treatment T1 by providing trichoderma agent in mixture top soil. Treatment was done before the seedling planted in the polybag. The treatment of Nasa was done one for week. The result of research showed that the growth of banana seedling have significant different to the treatment of Nasa liquid organic fertilizer, wich was the best concentration N1 (Nasa 2 ml/liter of water. The effect of interaction giving Trichoderma and Nasa, to almost the all of growth parameter were not significant different, except in increase the length of leaves. Al trought it have tendency T1N1  the best effect to the growth of all observation. The proves that the Kepok “Yellow” Banana seedling from tissue culture were fertile growing and healthy without disease attack. Except in treatment without trichoderma on the end observation.Several years ago at 2000 Kepok “Yellow” Banana plantation  in East Kalimantan was attached disease, so that the production was decrease therefor in vitro propogation was a preferred a n alternative method.

Abstract

Red Chilli is commodity of vegetable that has high economic value, but still has slow productivity. The objective of this study was identify the effect of indigenous microorganism (EM 4) application and compost to increased the growth and yield of Red Chilli Plant (Cappcicum annum L) on Ultisol. Field trial was conducted on Ultisols in Horticulture Experimental Station, BatuahLoajanan, Kutai Kartanegara. The soil was characterized by low fertility status. The amount of organic matter and microbial acivity are very low. This trial was started on January until April 2017 using Split Plot Design with three replications Main plot consisted of two levels treatment i.e. without EM-4 (E0) as control and Effective Mikroorganisms-4 (E). Sub-plot was four rates of organic compost i.e. 0, 10, 20 and 30 tons ha-1 and chili was used as test plant.Results indicated that EM-4 treatment showed a significant effect on fruit yield of chilli. It increased the fruit yield 38 percent compare to control. Compost application significantly increased on fruit yield. The relationship between unfermented compost rate and fruit yield shows a linear regression YE0 = 1.699 + 0.047 X (r = 0.95) and quadratic regression for EM-4 fermented compost YE1 = 1,175 + 0,319 X – 0.007 X2(R2 = 0.603). Optimum compost rate was 23 ton.ha-1.To increased fruit yield of chilli, EM-4 fermented compost should be applied into and it can decreased compost rate application.

Abstract

Tanah di Kalimantan Timur di dominasi oleh tanah Ultisol, tanah ini memiliki kesuburan tanah yang kurang menguntungkan bagi pertumbuhan dan produksi tanaman padi sawah.Penelitian ini telah dilakukan di lahan sawah milik petani di Desa Bukit Raya, Teluk Dalam, Kabupaten Kutai Kartanegara.Tujuan dari penelitian ini yaitu untuk mengetahui pengaruh pengapuran dan pupuk NPK terhadap perubahan sifat kimia tanah dan produksi tanaman padi.Rancangan yang digunakan adalah Rancangan Acak Kelompok (RAK) Faktorial dengan dua faktor. faktor I adalah dosis pengapuran yang terdiri dari 3 tingkat yaitu P0, P1, P2 (0,1,2 ton Ha-1) dan faktor II adalah dosis pupuk NPK Granul terdiri dari 5 tingkat yaitu N0: 0 Kg Ha-1; N1: 100 Kg Ha-1 NPK Granul + 100 Kg Ha-1 Urea; N2: 200 Kg Ha-1 NPK Granul + 100 Kg Ha-1 Urea; N3: 300 Kg Ha-1 NPK Granul + 100 Kg Ha-1 Urea; dan N4: 400 Kg Ha-1 NPK Granul + 100 Kg Ha-1 Urea. Data tanaman meliputi tinggi tanaman (1 dan 2 bulan), jumlah anakan perumpun (1 dan 2 bulan), jumlah malai berisi rata-rata perumpun, berat rata-rata 1.000 biji GKG dan produksi GKG Ha-1. Hasil penelitian ini menunjukan bahwa perlakuan pengapuran pada tanah ultisol tidak menunjukan respon terhadap tanaman padi sawah sedangkan pemupukan nitrogen (N) menunjukan respon terhadap pertumbuhan dan produksi padi bersifat linier dengan persamaan yCa0 = 0.0049x + 2.6322 r = 0.8657 ;yC1 = 0.038x + 3.0745 r = 0.9210 ; yCa2 = 0.0071x + 2.321 r = 0.84342.
