Foliar application of nano-chelate and non-nanochelate of zinc on plant resistance physiological processes in cotton (Gossipium hirsutum L.). Mohammadali Rezaei* and Hossein Abbasi

Nano-fertilizers are designed in order to gradually release their food contents. They are also manufactured in such a way that the time of their liberation matches with the food product requirement. The use of nano-fertilizers leads to an increase in the efficiency of the consumption of food elements. With regard to the strategic importance of cotton plant and the effects of zinc in increasing ...

Investigating critical growth stage of cotton subject to water deficit stress . Fiaz Ahmad*, Shabab Ud Din, Asia Perveen and Mohammad Naveed Afzal

Critical growth stage of cotton crop was investigated by artificially imposing water stress under field conditions. The crop was given water deficit stress for a period of 30 days at squaring (SS) and first boll split (BS) phases by maintaining the leaf water potential (yw) at –2.2+0.2 MPa whereas in control plots yw was maintained at -1.6+ 0.2 MPa by irrigation scheduling. The average irrigati...

Underlying Constructs of Farmers’ Perceptions towards Bt Cotton Among Former Cotton Farmers in Northern Ghana: Empirical Application of Q Methodology

It is often argued that learning from best examples in the neighbouring Burkina Faso and elsewhere, Ghana can succeed in revamping the collapsing cotton industry by introducing Bt cotton to farmers. This paper therefore presents a survey findings on farmers’ views and perceptions towards the possible introduction of Bt cotton. A stratified random sampling techniques was applied in selecting 254...
