Abstract

ABSTRAK Penelitian ini bertujuan untuk mengetahui peranan beberapa tepung tanah yang mengandung mikoriza dari sekitar perakaran beberapa tanaman terhadap hasil tanaman kedelai. Percobaan dilaksanakan dengan Rancangan Acak Kelompok dengan tujuh perlakuan tepung tanah bermikoriza berasal dari sekitar perakaran tanaman; ubi kayu, kacang tunggak, jagung, bawang merah, kacang tanah, padi dan cabai. Perlakuan tanpa tepung tanah juga disiapkan sebagai kontrol. Semua perlakuan disiapkan sebanyak tiga ulangan. Data dianalisis dengan analisis sidik ragam pada taraf nyata 5%. Dari hasil penelitian diperoleh tanaman kedelai dengan perlakuan tepung tanah bermikoriza dari perakaran ubi kayu memiliki berat basah tajuk, berat kering tajuk, berat basah akar, berat kering akar tertinggi dan mampu meningkatkan masing-masing sebesar 211,7%, 180,63%, 308,7% dan 334,76% dibandingkan dengan kontrol. Disamping itu, tanaman kedelai dengan perlakuan ini juga memiliki jumlah polong, berat polong, berat 100 biji, berat biji dan serapan P tertinggi dan mampu meningkatkan masing-masing sebesar 367,45%, 152,48%, 149,04%, 135,15% dan 357,22% dibandingkan dengan kontrol. ABSTRACT The aim of this study was to determine the role of same soil flours, dry soil that finely grounded, containing mycorrhizas taken from root zones of some plants species on soybean yield. The experiment was conducted using completely Randomized Block Design with seven treatmens of soil flours containing mycorrhizas taken from root zones of cassava, cowpea, corn, shallot, peanut, rice and pepper. Every treatment was ripeated three times. Data were analyzed with analysis of variance at 5% significant level. Results showed that soybean plant treated with soil flours from cassava increased in fresh and dry weight, root fresh and dry weight, as much as 211.7%, 180.63%, 308.7% and 334.76%, consecutively compared to control. In addition, the treatment also increased number of pods, pod weight, 100 seeds weight, total seed weight, and P uptake at about 367.45%, 152.48%, 149.04%, 135.15%, and 357.22%, respectively, compared to control.

Abstract

This study aims to determine the diversity, abundance, and dominance of predators in potato plants treated by synthetic non-chemical insecticides on the medium plain of Lombok Island. The research used Randomized Block Design with ten different synthetic non-chemical insecticide treatments such as Metarhizium anisopliae, Beauveria bassiana, and Bacillus thuringiensis, Neem extract, tobacco stem extract, soursop leaf extract, babandotan leaf extract, chemical insecticide treatment, and one treatment without insecticide as a control. The insecticide was applied after 37 days of planting eight times at 7-day intervals. The type and population of predators were observed five days after the treatments. The diversity index (H'), abundance (K), and dominance (D) of the predators are then identified and determined. Data were analyzed by using a Diversity analysis followed by a 5% beda nyata jujur (BNJ). The yield shows six predatory families: Formicidae, Coccinellidae, Mantidae, Lycosidae, Oxyopidae, and Aranedae. H' and K values are generally classified as the low category, and no species dominates in each treatment (D <0.5). The value of H' and K in B. thuringiensis treatment was higher than other treatments. The highest D value was obtained from chemical insecticide treatment. Formicidae is the family with the highest population compared to other families

Abstract

Abstrak Salah satu cara untuk meningkatkan hasil tanaman jagung adalah dengan meningkatkan kemampuan intersepsi cahaya matahari, khususnya pada akhir fase vegetatif. Empat varietas jagung hibrida, Bisi 816 (PT. BISI International Tbk.), NK 22 (Syngenta), P21 (Pioneer Hi-Bred International Inc.) dan Pertiwi 2 (PT. Agrimakmur Pertiwi), ditanam pada tiga populasi yang berbeda, 71.428, 83.333, dan 100.000 tanaman/ha di lahan kering Lombok Utara. Percobaandirancang dengan Split-plot tiga ulangan, yang mana populasi tanaman ditempatkan sebagai petak utama dan varietas sebagai anak petak. Tanaman dipupuk dengan Urea 500 kg/ha (150 kg/ha saat tanam, 200 kg/hapada umur 35 HST, dan 150 kg/ha pada umur 56 HST) dan pupuk NPK Phonska (15-15-15) sebanyak 380 kg/ha (sebagian pada saat tanam dan sisanya pada umur 35 HST). Hasil penelitian menunjukkan bahwa varietas Pertiwi 2 memiliki tinggi tanaman dan sudut daun terbesar, masing-masing 216 cm dan 33,6o, sementara tinggi tanaman lainnya <210 cm dengan sudut daun <30o. Tidak ada perbedaan dalam hal intersepsi cahaya matahari dari keempat varietas yang diuji, namun intersepsi cahaya meningkat dengan meningkatnya populasi. Intersepsi cahaya pada populasi terendah pada akhir fase vegetatif adalah 76% dan pada populasi tertinggi adalah 91%. Hasil dari varietas NK 22 dan P 21 setara dengan 7 ton/ha dan hasil pada populasi tertinggi setara dengan 7,4 ton/ha dibandingkan dengan hasil pada populasi terendah setara dengan 5,4 ton/ha. Varietas jagunghibrida dengan sudut daun yang sempit dapat ditingkatkan populasi tanamnya untuk meningkatkan intersepsi cahaya matahari guna meningkatkan hasil di lahan kering. Abstract One of the ways to improve yield of maize is by improving its ability in intercepting sunlight, especially at the end of vegetative state. Four maize hybrid varieties, Bisi 816 (PT. BISI International Tbk.), NK 22 (Syngenta), P21 (Pioneer Hi-Bred International Inc.) and Pertiwi 2 (PT. Agrimakmur Pertiwi), were grown at three different populations, 71,428, 83,333, and 100,000 plants/ha on a dryland of North Lombok. Treatments were arranged in a Split-plot Design with three replications, where population density was assigned as main plot and variety as sub-plot. Plants were fertilized with 500 kg/ha Urea (150 kg/ha at planting, 200 kg/ha at 35 DAP, and 150 kg/ha at 56 DAP) and NPK (15-15-15) Phonska of 380 kg/ha (half at planting and the rest at 35 DAP). At the end of the vegetative stage, Pertiwi 2 was measured as the tallest and had the widest leaf angle, 216 cm and 33.6o, respectively while others varieties had <210 cm in height and <30o in leaf angle. No difference in light interception among the four varieties but light interception increased with the increase of population density. Light interception at the lowest and highest population density was 76% and 91%, respectively. Yields of NK 22 and P 21 were equal to 7.0 ton/ha, and the yield at the highest and the lowest population density was equal to 7.4 and 5.4 ton/ha, respectively. Population density of maize hybrid varieties with narrow leaf angle grown on a dryland can be improved in order to increase their ability to intercept sunlight that lead to a higher yield.
