Soybean [Glycine max (L.) Merr.] yield has increased over time through the introduction of new varieties and improved agronomic practices. However, seed protein concentration decreased. We conducted field studies in 2018 2019 to investigate effects fungicide, insecticide, foliar fertilizer application on grain quality two soybean maturity groups (MG). In-season treatments targeted nutrient avai...

The survey gives an overview of the achievements in topology of real algebraic varieties in the direction initiated in the early 70th by V. I. Arnold and V. A. Rokhlin. We make an attempt to systematize the principal results in the subject. After an exposition of general tools and results, special attention is paid to surfaces and curves on surfaces.

With the continuous improvement of mechanization level and development new crop varieties, optimal strip width for intercropping crops is important. In this study, field experiments were conducted to analyze effects different row spacings planting patterns on photosynthesis, chlorophyll fluorescence, related enzyme activities maize ear leaves in a maize–soybean system using two (wide–narrow row...

Asian rust caused by Phakopsora pachirhizi, which is a major constraint to production of soybean, causing 90% yield losses in field. Synthetic fungicides used control this disease are environmentally degrading and have negative impact on the health producers consumers. The use resistant soybean genotypes can be an effective alternative. aim work evaluate tolerance varieties under natural condit...

Abstract South Sulawesi has long been known as the largest soybean-producing province in Indonesia and one of its supporters is emergence several soybean varieties that have responsiveness adaptability to various agroecosystems are tolerant pests diseases. Several developed by farmers brought be producer include Wilis, Mahameru, Anjasmoro, Argomulyo. The Wilis variety emerged a superior era 198...

Dry land is that never flooded or inundated most of the time year. Soybeans tend to be planted after rice harvest in dry season (MK-I). Soybean planting can done with two cultivation technologies. The need for soybeans continues increase along population. Efforts soybean productivity have obstacles, one which pest attack. One common pests attack pod borer (Etiella zinckenella I); This research ...
