The outcome reveal that as the land use in the catchment areas change from mixed agricultural to cassava cultivation, the simulated loads and concentrations of nitrogen species from cassava land-use scenario recorded reduction. The resultant concentrations of nitrate and nitrite for both current and future land-use scenarios are all below the daily limit suggested by the WHO, (World Health Orga...

Black children born in the U.S. South in 1910 attended inferior schools and received three fewer years of education than their white peers. These racial differences diminished significantly in the following three decades, most notably in the Cotton Belt. Moreover, there was no major federal policy targeted at black schools during this period. I propose that the demand for child labor can explai...

Aims: To evaluate the effect of tillage methods on soil moisture storage, grain yield, economics and rain water use efficiency in semi-arid region
 Study Design: Four viz. conventional tillage, Rotovator ploughing + chisel ploughing, tiller conservation (Minimum with retention crop residue) at different time ploughing.
 Place Duration Study: Kovilpatti, a representative location regio...

Abstract This article presents the results of scientific research on use cotton drip irrigation technology in conditions water scarcity, saving resources, assessing growth and yield cotton. At same time, cultivation “Bukhara-102” variety was compared with options grown traditional way. During experiments, control field for Bukhara-102 cotton, i.e. 1st variant, which irrigated by land invasion, ...

Expansion of cultivated land diminishes the extent of forestlands or reduces the length of fallow periods and, hence, reduces the amount of natural vegetation. The increase in land under cultivation has a direct output-increasing effect at the cost of reducing natural capital and agricultural productivity. The evidence for western Côte d’Ivoire is consistent with, and provides an explanation fo...

Winter irrigation is an effective means of salt leaching, but the long-term effect on salinity unclear. In 2008–2019, three different soil types farmlands were selected as study area by drip under film mulch combined with periodic winter in non-growth period. The 0–150 cm well survival rate and yield cotton growth periods monitored, respectively. mass fraction decreased rapidly irrigation, then...

The effects of drip irrigation and different cultivation methods on seedgermination and growth of Puccinellia tenuiflora in saline-sodic soils wereinvestigated in field experiments during 2008-2010 in the Songnen Plain, China.Drip irrigation was applied to waste saline-sodic P. tenuiflora grasslands for bothflat and ridge cultivation methods. Drip irrigation affected the distributions ofelectri...

Dry seeds of four cotton varieties were irradiated with 0, 10, 15, 20 and 25 kR doses of gamma irradiation from Co source of gamma irradiation in 2012 at Nuclear Institute for Food and Agriculture (NIFA), 60 Tarnab, Peshawar, Pakistan. Three highly potential cotton varieties i.e. Gomal-93, Bt-131 and Bt-CIM-602 with irradiation of 15, 20 and 25 kR, respectively selected for the second year (May...
