Drought: A constraint in the efficacy of systemic pesticides

| | No Comments

Rise in the global temperature, erratic fluctuations in rainfall and severe and prolonged drought periods due to climate change seems to have a dramatic impact on agricultural production systems. Insect pest populations in agricultural and horticultural systems are also expected to be impacted, both in terms of their spatial and temporal distributions and in their […]…Read More

Drought causes, impact and solution

| | No Comments

article image Climatic changes and global warming are the major issues of 21 st century. Plants are consistently exposed to biotic and abiotic stresses. Harmful effects resultant from global climate changes possibly impart losses in crop productivity. Among abiotic stresses, drought is pondered as the single most caustic environmental stress, which not only affects the plant growth and development but also decreases the crop productivity. A continuous deficit…Read More

Potassium (K) mandatory for plants under drought condition

| | No Comments

article image Potassium is one of the major nutrients which is required for the plant growth and development. It is the most essential element in plant’s life as it increases root growth and contributes for water relations of plants making them to survive under drought conditions. Potassium is critically needed for maintaining water relations of plant, activating enzymes, supporting photosynthetic systems, translocating sugars and starch out of the leaves. The plants take up potassium in ionic form…Read More

Impact of heat & drought stress on physiological, biological processes in plants

| | No Comments

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

Thar drought and migration

| | No Comments

THIS YEAR, due to lack of monsoon rains, the area is again experiencing a drought and the district government has already recommended declaring the district as calamity-hit. There are indications that the situation might turn out to be more serious than it was in 1985-87 and 1999-2000 when Tharparkar had its worst droughts in last three decades.The last year’s delayed devastating rains, causing immense runoff, left more than two-thirds area with no grass/crops. Even the undamaged parts…Read More
