Crop Production and Global Environmental Issues by Khalid Rehman Hakeem

By Khalid Rehman Hakeem

Meeting the world’s nutrients safeguard problem would require a multi-national, collaborative attempt to combine the easiest examine from technological know-how, engineering and socioeconomics in order that technological advances can carry advantages the place they're so much wanted. the current publication covers the impact of significant environmental difficulties on crop construction and the way to deal with those concerns for sustainable agriculture and enhancements of plants.

The world’s inhabitants is expected to hit 9.6 Billion via 2050, up from today’s overall of approximately 7.3 Billion, and with it nutrients call for is anticipated to extend considerably. The post-war ‘second agricultural revolution’ in constructed nations, and the ‘green revolution’ in constructing countries within the mid- Sixties switched over agricultural practices and increased crop yields spectacularly, however the final result is levelling off and won't meet projected call for. at the same time, crop construction is tormented by many different components, together with commercial pollutants, overuse of fertilizers and pesticides, heavy steel and radiation stresses and so forth. it's been famous that many pests have gotten proof against pesticides. Estimates differ, yet round 25% of plants may be misplaced to pests and ailments. weather switch linked to agriculture is usually a world factor. Agriculture is an important contributor to greenhouse gases and is envisioned to account for 10-12% of overall greenhouse fuel (GHG) emissions. the various concerns highlighted are international difficulties and are addressed thoroug

Radiations between 500 and 600 nm are assisted by accessory pigments as they have low ability to be absorbed in pure chlorophyll (Campillo et al. 2012). Infrared radiation has wavelength ranges from 760 nm to 4000 nm (Campillo et al. 2012). These radiations have small quantum because of their longer wavelength. The biological effects of these radiations depend upon the absorption of the energy. These rays penetrate 20 mm into the tissues (Kovacs and Keresztes 2002). UV radiations have shorter wave length ranges from 200 nm to 400 nm.

Mung bean cultivars HUM 1 and HUM 12 also showed cupping and folding of leaves and the development of light purple necrotic patches due to elevated UV-B levels (Choudhary and Agrawal 2014a). Choudhary and Agrawal (2014b) also demonstrated morphological changes due to UV-B in another study on pea cultivars such as decrease in leaf area, root nodules, and root-to-shoot ratio in field conditions. Floral morphology of crop plants is also observed to change due to UV-B exposure. This in turn affects reproduction of the crop plants which ultimately affects yield.
