NITROGEN EFFECIENCY IN MAIZE UNDER SALINE-SODIC CONDITIONDS AS AFFECTED BY UREA IN COMBINATION WITH SOME ORGANIC AMENDMENTS

Bacteria in combination with fertilizers promote root and shoot growth of maize in saline-sodic soil

Salinity is the leading abiotic stress hampering maize ( Zea mays L.) growth throughout the world, especially in Pakistan. During salinity stress, the endogenous ethylene level in plants increases, which retards proper root growth and consequent shoot growth of the plants. However, certain bacteria contain the enzyme 1-aminocyclopropane-1-carboxylate (ACC) deaminase, which converts 1-aminocyclo...

urease activity in maize (zea maize l. cv. 704) as affected by nickel and nitrogen sources

nickel (ni) is one of the essential micronutrients for higher plants and its known function is beingthe metal component of urease. the effects of various ni levels on urease activity in maize (zea maize l.)plants grown in two nutrient media containing urea or ammonium nitrate as two separate nitrogen sourceswere investigated. the experiments were performed as completely randomized blocks with t...
