Abstract

The Interaction Water Deficiency Level and Soybean Varieties [Glycine max (L) Merr] Capacity to the Plant Growth, Product and Prolin ContentABSTRACT. The research was conducted to study the interaction water deficiency level and soybean varieties to capacity of the plant growth, product and prolin content. The experiment as factorial experiment in a completely randomized design was applied. The first treatment factors were three level varieties soybean: Kipas putih, Wilis, and Singgalang. The second factor were four level water deficiency: no water deficiency along the growth period, water deficiency along early vegetative growth period, water deficiency along early active of vegetative growth period, water deficiency along flowering, and forming and seed filling period, and water deficiency along seed maturity period. The results showed the water deficiency along each growth period decreased the growth and production. In contrast the water deficiency increases the plant prolin content. The water deficiency along flowering, forming and seed filling period decreased number of pod of all variety. The variety Kipas Putih decreased about 42.49% were compared to the same criteria with no water deficiency in all growth period where water given in normal amount along the through growth period.

Abstract

Toxicity of enthomopathogenic fungi Beauveria bassiana to armyworm (Spodoptera litura) has been investigated in Pest Laboratory of Faculty of Agriculture, Syiah Kuala University, Darussalam, Banda Aceh. This research was aimed at determining lethal concentration (LC50) and lethal time (LT50) of B. bassiana suspensions against third instar larvae of armyworm. The fungi concentration used was in the range 0-6 % (w/v) or equal to 9,33 x 106 – 45,83 x 106 conidia/ml. The fungi suspension was applied to the larvae by dissolving the larvae into the suspension for 10 seconds. The number of the larvae died and the time required to kill the larvae were recorded everyday starting one day after application (DAA) until pupation. The relation between each observation to the fungi concentration was analyzed using probit analysis. The result showed that B. bassiana suspension caused the death of the larvae beginning 4 DAA with maximum eath on 10 DAA. The death of the larvae caused by the growth and the development of the fungi inside the larvae. The LC50 of the fungi suspension against the larvae was 3,57 % while the LT50 at 4, 5, and 6 % fungi concentration were 9,88; 8,13; and 6,8 days respectively.
