Historical prospects and importance of biological control

| | No Comments

What is biological control? It is a technique of controlling organisms including (insects, mites, weeds and plant diseases) by means of certain other living organisms or their products. It is a way of keeping pests below economic injury levels by the action of microbes, predators and parasitoids. Biological control is an element of an integrated pest management approach. It is an environmentally safe and efficient means of reducing pests by the use of natural enemies. Biological…Read More

Biological anaerobic treatment: the way forward

| | No Comments

ONCE PAKISTAN was a water-surplus country, but today it is a water deficit country. The water availability started decreasing from 5,600m³ per capita at the time of independence to 1,299m³ per capita in 1996-97, while in 2006 it further decreased to 1,100 m³ per capita, currently it is estimated 950m³, and projected to less than 700m³ per capita by 2025. Therefore, search for other non-conventional water resources i.e. wastewater treatment for daily use and irrigation has become most…Read More

article image Heat and drought are the main abiotic constraints in harvesting potential yield of the crops on sustained basis. Climate change has a serious threat to cereal production levels required to feed future generations across the globe, hence create food insecurity. Global warming is predicted to increase the frequency and severity of heat waves’ in crops growing areas in the world. Heat stress to varying degrees at different phonological stages causes a substantial yield reduction,…Read More

Biological nitrification inhibition-an efficient approach

article image Nitrogen (N) is an essential element, needed by plants in highest quantity followed by carbon. It is crucial for the synthesis of proteins, DNA, RNA, chlorophyll, vitamins, plant hormones and many other biomolecules. Almost 20-50 g of nitrogen is taken up by the plant to synthesize 1 kg of dry matter thus crop yield is highly dependent on nitrogen supply. Annually 88 Mt of nitrogen fertilizer is utilized by agriculture sector. Agriculture sector is the main contributor towards the global…Read More

article image Environmental pollution is a major concern in Pakistan and this problem is constantly on the rise. The situation is worsening due to unchecked disposal of industrial and municipal effluents into local environments, spills during transportation, leakage from waste disposal and storage sites, hospital wastes, urban solid waste and excessive agrochemicals application in agriculture. These are the factors mainly contributing to the deterioration of agricultural lands and water quality. In…Read More

Biological nitrification inhibition-a breakthrough

| | No Comments

article image NITROGEN IS the most important element in plant nutrition beyond any doubt. Its multifunctional nature places it to the most distinguished rank among nutrients. It plays a vital role in plant metabolism, physiological activity, defense mechanism, growth, development and efficiency by influencing a number of key enzymes, precursors and metabolites. Nitrogen is most abundant gas in air (about 79 per cent) but unfortunately plants are unable to use this atomic N and thus uptake from root zone…Read More
