The fact that most soils in Malawi are acidic has been known for some time and such soils have detrimental effects on tobacco production. Correcting soil acidity is achieved by proper liming regimes with the aim of increasing soil pH and the...

Avery (1933) studied the growth of the whole tobacco leaf and some of its segments and concluded a different growth intensity of some of the leaf areas. But, the problems of a chemical heterogeneity of some leaf segments are of the extreme...

Experience has shown that seeds that are large and rich in endosperm provide young plants with a more abundant food and thus ensure a more vigorous growth in the first stages of life. An experiment was launched in order to investigate problems...

The objective of this trial was to evaluate the cost effectiveness of a simple means of providing supplementary solar energy for bulk barns. A group of sixteen gas fired barns was used, arranged in two rows of eight under a continuous common roof...

Three suckercides were compared for their efficiency in an experiment: Sucker Out, pendimethalin (Stomp) and flumetralin 125 EC. The trial was conducted with five following treatments: 1) flumetralin 125 EC: 15 ml per plant of a solution with 1.35 %...

From the year 1996 to 2000 some experiments were made in 5 locations of the country in order to compare the traditional fertilization with 4 other alternatives including potassium nitrate. All treatments resulted in increased yields, higher number of...

The West part of Iran is located between Turkey, Iraq and Zagros chains. These provinces are known as a mountainous, cold area with fairly short summers. For centuries tobacco farmers of this region have cultivated different oriental and other local...

The purpose of this work, based on a three years of field experiment, was to inspect whether it is possible to use a chlorophyll meter in fixing the nitrogen doses used in growing flue-cured tobacco. The relationship between the capacity of nitrogen...

Four tobacco varieties (three oriental and one semioriental) and their diallel hybrids from F1, F2 and BC1 generations were investigated during 1997, in order to study the characters: height of the stalk, number of leaves per stalk and dry mass yield...

The trial was set up on a diluvial soil type, at the Experimental field of Tobacco Institute in Prilep, using the tobacco type Burley, variety Chulinec. Two factors were investigated: irrigation with two amounts of water (50 and 70% of the field...
