          Technological advances the Argentine has been in recent years such that now stands at the forefront worldwide. The explosion of agriculture, tillage, GM crops and the widespread use of glyphosate have raised controversy, especially regarding the toxicity of the latter. Before weeds are controlled with tillage and these involve serious problems of erosion and soil degradation. Tillage and herbicides have changed the situation and consequently the sustainability of production systems.

Onion thrips (Thrips tabaci Lindeman) are dual destructive as both pests and vectors of Tospo viruses. Thrips tabaci has impact on a wide range of crops. Thrips damage, thrips count, leaf parameters, tolerance, susceptibility and onion yield of thirteen onion genotypes and three commercial onion cultivars were tested. The results of TAUIPC (Total Area Under Infestation Pressure Curve) showed that the accessions having their average leaf damage below two namely VIO38552, VIO38512 and AVON 1067 were categorized as the most tolerant accessions among the tested genotypes.

An experiment was conducted to study the effect of bagging on growth and development of mango (Mangifera indica L.) cv. Alphonso in the year 2012 from March to June, undertaken in Randomized Block Design. Mango fruits were subjected to six types of bagging treatments with 3 replications at 60 days after fruit set. Results showed that the chemical parameters such as moisture content, acidity, TSS, reducing, non-reducing sugars and β-carotene were not significantly varied due to bagging.

Lemons (Citrus limon Burm.) were evaluated for their tolerance to carbonyl sulfide (COS) fumigation and the influence of COS on market quality. At 70 mg l-1 no significant deleterious changes occurred in market quality up to a fumigation duration of 8 h and only a slight amount of peel injury was observed after 12 h. Longer fumigations lead to the presence of an offensive off-odor in the juice as well as to increasing rind injury.

Sweet Corn Production

Sin votos aún
Su voto: Nada

Sweet corn is a crop that lends itself well to small-scale and part-time farming operations. Initial investment is relatively low, and many field operations - such as land preparation, planting, and harvesting - can be custom-hired. Equipment needs on a small-acreage farm are not very great, and most of the equipment can be used for other purposes.

and moss killer. Ammonium soaps are permitted as animal repellants
provided there is no contact with edible portion of crop or with soil. Soap is
not currently permitted for use as a fungicide or herbicide. (NOP 2000).
The USDA-NOP regulation does not describe the type of soaps permitted,
though the initial review was for potassium salts of fatty acids. Soaps
classed by EPA as List 4 inerts (inerts of minimal concern) may be used as
inert ingredients and adjuvants.
