Abstract

Research applications straw and rice husk as ameliorant on peat soil to improve the growth and production ofsoybean in the peat soil was conducted from April to August 2012, at green house of the Faculty of Agriculture,University of Islamic of Indragiri. The objective was to get the best composition application ameliorant straw and ricehusk on peat soil on the growth and production of soybean. The experiment was used the completely randomized designwith a single factor consisting of 8 treatments (control, 3 tons.ha -1 of AJP, 3 tons.ha-1 of ASP, 3 tons.ha-1 of KJP, 2 tons.ha-1 of KJP + 1 tons.ha-1 of AJP, 2 tons.ha-1 of KJP + 1 tons.ha-1 of ASP, 1 tons.ha-1 of KJP + 1 tons.ha-1 of AJP and 1 tons.ha-1 of KJP + 1 tons.ha-1 of ASP) with 3 replications. Observations of each parameter analysis of variance (F test) and thedifference in treatment was continued with DNMRT (Duncan’s New Multiple Range Test) at 5% level. The results showedgranting ameliorant 3 tons.ha-1 of AJP can improve plant growth in terms of height that 51.16% (145.75 cm), ratio of theroot crown (4.86 g) dry stover weight of 1232.59% (24.12 g) soybean crop production, including number of 272.72% ofpods per plant, number of seeds per plant and seed weight 335.87% 333.23% dry. compared with no treatment.

Abstract

The objective of this study is to determine the value of general combining ability, and specific combining abilityhybrids of parental crosses by half-dialel scheme on the peat land. The experiment was carried out on the peatlandRimbo Panjang Faculty of Agriculture Riau University.The genotypes consisting of 15 crosses from IPB half dialelcrosses chili in three replicates. To analyze general combining ability (GCA) or specific combining ability (SCA)influence of the variable, analysis of variance for diallel cross according to Griffing’s method 2 was used. The resultshows, the highest value of general combining ability of stem diameter, fruit diameter, fruit weight and total weight perfruit were obtained from genotype C5. Genotype C159 has high value of general combining ability of plant height, stemdichotomous and crown width, and Genotype C 120 has high value of general combining ability of length fruit.Meanwhile the highest specific combining ability based on yield component is genotype C5xC120

Abstract

The purpose of this research was determine how the effect of lands use change from natural forest to plantationforest Acacia crassicarpa on some physical properties and chemical properties of peat soil. The research conducted inthe PT. BBHA, Bukit Batu Subdistrict, Bengkalis Regency, and Laboratory of Soil Science Agriculture Faculty, RiauUniversity. The research was conducted by survey method, with purposive sampling. Data was analysed by descriptiveand graphics model. The parameters were particle size distribution, bulk density, particle density, porosity, pH, organiccarbon, total nitrogen, total phosphor and base cations (K, Ca, Mg and Na). The result of research show that land usechange from natural forest to plantation forest Acacia crassicarpa was increasing total of smalles particle, bulk density,and particle density, while the porosity decreases. Then the increasing were pH, total nitrogen, total phosphor, and basecations K, Ca, Mg, Na is fluctuative, whereas for organic carbon was linierly. The longer time of land use change wasincreasing the decomposition of peat soil, which improves the physical properties and chemical properties of peat soil.

Abstract

The study aims to determine the effect of chicken manure and spacing, and to obstain interactionthe best doses of chicken manure and spacing for growth and production of shallots.This research has been carried in Experimental Station Faculty of Agriculture University of Riau from October 2017 to January 2018. This research was conducted in a factorial which was arranged in a complete randomized design consisting of 2 factors and 3 replications. The first factor is chicken manure which is without chicken manure, 10 ton.ha-1, 20 ton.ha-1 and 30 ton.ha-1, and the second factor is spacing of 10 cm x 15 cm, 15 cm x 15 cm and 20 cm x 15 cm. The data obtained were further tested by Duncan's Multiple Range Test 5%. The interaction chicken manure and spacing were significant in increasing fresh tuber weight and tuber weight worth keeping and the interaction of chicken manure application and spacing was not significant in increasing plant height, number of leaves per clump, number of tubers per clump and tuber wrap. The giving of chicken manure at a dose of 30 ton.ha-1 and a spacing of 20 cm x 15 cm resulted in a tuber weight worth the highest, namely 1193,80 g.m-2(11,938 ton.ha-1)Keywords: Shallot, chicken manure, plant spacing and soil Inceptisol

Abstract

This study aims to know the effect of combination and the main effect of giving manure and N,P,K fertilizer towards the growth and the production of rice plant and knowing the dosage of manure doses and N,P,K fertilizer on the growth and production of rice in rainfed land. This study was conducted in Binuang Village Bangkinang Sub-district Kampar Regency Riau Province. This study used a randomized block design (RBD) of 2 factors and 3 replications. The first factor was 3 levels of manure and the second factor was 4 levels of N, P, K fertilizer. The observation parameters consisted of plant height, maximum number of tillers, number of productive tillers, age out panicle, panicle length, number of grains per panicle, dry grain weight milled per plot andweighs 1,000 grains of grain. The combination of manure and N, P, K fertilizer  at 10 tons.ha-1 manure dosage with a dose of 138 kg N, 54 kgP2O5 , 60 kg K2O showed better results on the parameters ofthe maximum number of tillers, number of productive tillers, number of grain per panicle. The main factors of manure and N, P, K fertilizer showed better results on the parameters of the maximum number of tillers, number of productive tillers, age out panicle, panicle length, number of grain per panicle and dry grain weight milled per plot. Keywords : Rice plant, manure, N, P, K fertilizer, rainfed land

Abstract

Hama utama yang menyerang kelapa sawit adalah hama kumbang tanduk (Oryctes rhinoceros). Aplikasi tandan kosong kelapa sawit (TKKS) pada budidaya kelapa sawit yang berfungsi sebagai mulsa dan kompos, sebaliknya O. rhinoceros justru meningkat populasinya dengan aplikasi TKKS. Penelitian bertujuan untuk mendapatkan aplikasi berbagai ketebalan lapisan TKKS pengaruh terhadap O. rhinoceros dan peningkatan kimia tanah. Penelitian menggunakan metoda eksperimen dalam rancangan acak lengkap dengan 3 perlakuan dan 5 ulangan. Uji lanjut dengan BNT taraf 5%. Perlakuannya adalah ketebalan lapisan TKKS yaitu 1 lapis, 2 lapis dan 3 lapis. Parameter pengamatan adalah populasi pradewasa (telur, larva, dan pupa) O. rhinoceros. Pengaruh terhadap peningkatan kadar hara pengamatan analisis kimia tanah dilakukan diawal penelitian dan diakhir setelah 3 bulan aplikasi TKKS sebanyak 1 lapis. Pengamatan meliputi peningkatan pH H2O, C organik, N total, P total dan K total. Hasil penelitian menunjukkan bahwa pada ketebalan TKKS 1 lapis dan 2 lapis populasi pradewasa O rhinoceros sama yaitu 4,60 ekor, sedangkan pada TKKS 3 lapis yaitu 18,8 ekor. Dengan demikian pada ketebalan TKKS 1 dan 2 lapis bisa diaplikasi sebagai mulsa karena tidak berdampak besar terhadap populasi pradewasa O. rhinoceros. Aplikasi TKKS meningkatkan hara tanah sebagai berikut pH H2O dari 3,32 menjadi 5,36, C organik dari 8,86% menjadi 13,09%, N total dari 0,1% menjadi 0,45 %, P total dari 44,01 menjadi 54,82 mg/100, K total dari 14,03 menjadi 187,06.
