An experimental study on growth of Hopea mengarawan Miq. seedlings under different light intensity was conducted from June to October 2012 at open field. This experiment aimed to find out optimal light intensity for the growth of H. mengarawan seedlings. The study used completely randomized design with four treatments and six replications. The treatments were control (100), 80, 60 and 40% of light intensities. The result showed light intensity did not give significant effect to the growth of H. mengarawan seedlings.

Research of effect of light intensity towrd on Raphanus sativus tuber has be done, beginning at 1 August 2009-15 Decenber 2009 in paddy fields Popongan Salatiga. This research used design randomized complete block design, one treatment is given light intensity as low light intencity with one piece plastick strimin, two pieces strimin as medium light intencity, and high intencity without strimin plastick as controls. Every treatment was reapeating 5 times. Analysis data used komputer programs SPSS-13. Result this showed that given defferent light intensity on plant caused defferent on long and wet and dry tuber formation in first harvesting The second harvesting that 60 day age plant caesed defferently on total folium, wide and west and dry folium.

Tribulus terrestris merupakan tanaman yang mengandung berbagai macam komponen, antara lain saponin, flavonoid, dan asam amino untuk obat hipertensi serta jantung koroner. Ketersediaan tanaman Tribulus masih terbatas, karena budidaya Tribulus masih jarang dilakukan oleh petani. Pengelolaan budidaya Tribulus dengan pengaturan intensitas cahaya yang berbeda dan tanah salin akan dikaji pada penelitian ini yang diharapkan dapat diketahui tingkat toleransi intensitas cahaya dan kadar salinitas tanah pada budidaya Tribulus . Tujuan penelitian ini untuk mengetahui pengaruh intensitas cahaya, pengaruh aplikasi NaCl dan interaksi antara kedua faktor tersebut terhadap pertumbuhan tanaman Tribulus. Penelitian dilaksanakan pada bulan Juni-Agustus 2017 di Kebun Percobaan Fakultas Pertanian UNS di Kecamatan Jumantono, Karanganyar. Penelitian ini menggunakan Rancangan Acak Lengkap pola tersarang dengan dua faktor perlakuan dan tiga ulangan. Faktor pertama adalah naungan dengan 4 taraf (0, 25, 50 da...

is a source of carbohydrates that can be used as food and industrial raw materials. Monosodium Glutamate (MSG) is a type of food additive that functions as a flavor generator or is recognized by the public as a food flavoring. This study aimed to analyze the effect of sunlight on corn sprouts (Zea mays) that were given MSG and those that were not given MSG and to study more deeply the growth of corn sprouts (Zea mays) given MSG. This research was conducted with two experiments, namely indoors and using sunlight. The results showed that the observation of corn plants using MSG on the first day, planted in the sun with a height of 1 cm, on the first day, the second plant was planted indoors with a height of 1.3 cm. On the fourth day, the plant planted in the sun was 6.5 cm high, the second plant, grown indoors on the fourth day was 7.5 cm high. On the seventh day, the plants grown in the sun using MSG solution were watered up to 15 cm in height, while the second plant grown indoors was watered with MSG solution reaching 16 cm in height. Observation of plants using water on the first day, plants planted in the sun were 1.5 cm tall, while plants grown indoors were 1.1 cm tall. On the fourth day, plants that were watered using ordinary water were planted in the sun with a height of 6 cm, while plants grown indoors, watered using water were 6.5 cm high, the seventh day, or the last day the plants were watered using water below. sunlight reaches 10.2 cm high, while plants grown indoors reach 12.5 cm high. Based on the research that we have made, we come to the conclusion that: that plants given msg have a negative effect on making plants fertile quickly and quickly wither away, while plants given ordinary water on corn plants have a positive impact on fertile plants and do not wither, only their growth is so long.
