Estimation of avoidable yield loss due to sucking pest complex in blackgram

An experiment was laid out with two treatments viz., unprotected and protected plot with plot size of 100 m2 each and further each treatment was divided into 13 quadrates with 30 X 10 cm spacing in Randomised Block Design (RBD). Results revealed that the avoidable reduction in plant height, number of branches per plant, pods per plant, number of seeds per pod due to insecticides application is 19.14, 19.78, 20.70 and 17.80 per cent respectively and a significantly higher yield was obtained in protected plots i.e. 1028 kg ha-1 , while, comparatively low yield i.e. 759 kg ha-1 was recorded from unprotected plots. The yield increased in protected plots over unprotected was 269 kg ha-1 i.e. 35.44 per cent. The avoidable yield loss was 26.16 per cent by spraying of insecticides i.e. monocrotophos 36% SC and fipronil 5% SC at ten days intervals against sucking pests viz., whiteflies, thrips, aphids and leafhoppers in blackgram.

Nanotechnology and its importance in micronutrient fertilization

The increase in population and reduction of available land and water resources are major concern for agriculture to meet food requirement. The possible growth in agriculture can be achieved by increasing productivity through soil, water and nutrient management supported by an effective use of modern technology like nanotechnology. The small size, high specific surface area and reactivity of nano fertilizers compared to bulk fertilizers may increase the solubility, diffusion and availability of nutrients to plants and enhance crop productivity. Nanotechnology has provided the feasibility of exploring nanostructured materials as fertilizer carrier or controlled-release vectors for building of the so-called smart fertilizers, as new facilities to enhance the nutrient use efficiency and reduce the environmental pollution.
