Effect of different zinc management practices on growth, yield, protein content, nutrient uptake and economics on rice under partially reclaimed salt-affected soil

Abstract

A field experiment was conducted during Kharif season of 2013 at students instructional farm, Narendra Deva university of Agriculture & Technology Narendra Nagar Faizabad (Uttar Pradesh) to study the effect of zinc management practices on rice with variety Arize-6444. The results revealed that the treatment T2: soil application of 50kg ZnSO4 ha-1 recorded maximum protein content (8.45%), grain yield (7.11 t ha-1) and straw yield (8.45 t ha-1) followed by T3 and T5. The treatment T2:soil application of 50kg ZnSO4 ha-1 also recorded maximum nutrient uptake and economics, resulting maximum total N uptake, Zn uptake by grain (146.34 and 1.06 kg ha-1) and net return (Rs.82607) and benefit cost ratio (2.34) followed by T6 and T4.
