    A Physiological Approach: Nitrogen Management and Sub-1 Rice Varieties Grown in Flood Prone Ecosystem
    (International Journal of Current Microbiology and Applied Sciences, 2020) Pandey, Anand Kumar
    Farmers in flood prone areas mostly use only urea without any solid recommendations. Possibilities of recurrent flooding/submergence during the season are one of reasons for avoiding nutrient application, through it has a strong bearing on regeneration growth and yield of rice varieties after floods, hence suitable nutrient management strategies are essential to enhance the productivity. However, higher dose of N (60 Kg ha-1 as basal) showed positive response on plant growth during submergence but higher elongation caused plant mortality during post oxidative phase. Meanwhile, popular package and practices among flood prone farmers, addition of Zero Kg N before submergence to minimized risk was not justified. So far, higher N applied as basal showed negative effect on survival during post submergence. Plants grown without N fertilizer before submergence showed 12-23% plant mortality in both Sub-1 rice varieties during post oxidative phase even though submerged field was substituted with higher dose of N @60 kg ha-1 at 5th days after desubmergence, mainly due to energy starvation during submergence. After de-submergence frequent addition of split doses of N might be helpful to meet out the demand of submerged plants for faster recovery.

    Foliar spray of salicylic acid and oxalic acid ameolirates temperature (Heat) stress on wheat at anthesis stage
    (International Journal of Chemical Studies, 2020) Pandey, Anand Kumar
    This study endeavors to quantitatively cognize the impact of changes in physiological mechanism due to climate change on wheat at vegetative stage and reproductive stage of crop. This experiment was conducted and evaluated for wheat crop using two chemicals salicylic acid and oxalic acid and meteorological data from a field site at Students Instructional Farm of the Narendra Deva University of Agriculture and Technology, Kumarganj, Faizabad (U.P.) during Rabiseasons of 2015-16 and 2016-17. This experiment was planned under FRBD (Factorial Randomized Block Design) with three replications and two date of sowing viz; 25th November and 25th December with two varieties NW-5054 and NW-2036.Results indicated that physiological traits were adversely affected by time of sowing due to onset of high temperature during crop growth and particularly grain filling. All the treatments reduced the detrimental effect of heat stress on both the varieties by improving physiological traits which ultimately helped in obtaining higher yield.
