    Identification of Rice Genotypes for Submergence and Yield Attributing Traits
    (International Journal of Current Microbiology and Applied Sciences, 2020) Dixit, Saurabh
    Altogether 334 rice lines alongwith8 global check varieties were tested for submergence survival and yield performance at Crop Research Station, Masodha, Ayodhya. These lines and check varieties, namely IR 64-Sub 1, Swarna-sub 1, Sambha Mahsuri-Sub 1,. Ciherang-Sub1, TDK1, Ciherang, RC18, SambhaMahsuri and 3 local check viz. Swarna, MTU 1010 and Sahabagidhan were laid out in augmented design with 10 blocks. For survival testing in submergence, the experiment was conducted in the submergence pool and for yield performance (optimal condition), the experiments was conducted in the irrigation field. Each entry was direct sown in two rows of 3 meter length and after 25 days of sowing complete submergence of one meter water depth was imposed for 20 days. Data recorded for submergence survival as no. of plant counted before and after submergence. In yield performance experiments observation recorded on days to 50% flowering, plant height, Ebt/m2, total biomass, harvest index and yield kg/ha.

    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.

    Effect salinity on germination percentage (%) and seed vigour index of rice (Oryza sativa L.)
    (Journal of Pharmacognosy and Phytochemistry, 2020) Singh, Ankit
    Present investigation was conducted during Kharif 2017-18 in laboratory, at experimental study Department of Crop Physiology, Narendra Deva University of Agriculture and technology, Kumarganj Faizabad (U.P.). Soil salinity has become a severe threat to ensure food security, salinity-imposed limitations on plant growth. At the present, salinity level stimulates many of the metabolic processes involved in phases (2nd, 4th, 6th, 8th and 10th day) of germination, resulting in an improved performance of germination and higher. Experiment was laid out in complete randomized design (CRD) with three replication on six genotypes of rice crop i.e. tolerant- CSR-36, CSR-43, Usar Dhan-3 and Susceptible- Swarna Sub-1, IR-28, Pusa-44. Present investigation was carried to study the effect of salinity with 0, 50 and 100 mM concentration of NaCl on germination. The exposure of rice varieties to increasing concentration of NaCl had significantly increased germination (%), seed vigour index. It is evident from the result that concentration with NaCl significantly improved the germination and enzymatic activities of rice genotypes. The concentration are effective in increasing the germination percent, Seed vigour index, radicle length, plumule length, and enzymatic activities like α- amylase, catalase and carbohydrates biochemical parameters like proline accumulation, in all varieties under normal as well as under laboratory condition. The concentration with NaCl 0, 50 and 100 mM influences the germination and biochemical changes under normal as well as under anaerobic condition and might be useful in mitigating the adverse effect of laboratory condition or helpful in increasing the yield and yield attributes in all the varieties. Thus, it may be recommended that salinity level with concentration (0, 50 and 100 mM) of NaCl is the most desirable for mitigating the adverse effect of salinity.

    Effect of Moisture Regime on IW/CPE Ratio on Soil Properties, Yield and Water use Efficiency of Wheat Crop (Triticum aestivum L.)
    (International Journal of Current Microbiology and Applied Sciences, 2020) Pal, Sudhir
    The field experiment was conducted at Instructional farm of A.N.D University of Agriculture and Technology, Kumarganj, Ayodhya (U.P.) during Rabi, 2016-17. The treatments was comprised with five levels of irrigation viz. CRI stage (I1), 0.6 IW/CPE ratio (I2), 0.8 IW/CPE ratio (I3), 1.0 IW/CPE ratio (I4), and 1.2 IW/CPE ratio (I5) in Randomize Block Design with four replications. The results reaveled that the highest fresh and dry weight and density of root, grain and straw yield by crop were recorded with 1.0 IW/CPE ratio (I4) moisture regime followed by 1.2 IW/CPE ratio (I5) and minimum with CRI stage (I1), 0.6 IW/CPE ratio. The maximum reduction in pH and EC and buildup in organic carbon were recorded of (I4) 1.0 IW/CPE ratio (6 irrigations). The maximum moisture extraction was noticed in the upper most soil layer i.e. 0-20 cm followed by 20- 40 and 40-60 cm depth. Increasing levels of moisture regimes from CRI stage (I1) to 1.2 IW/CPE ratio (I5) increased the moisture extraction. The increment in extraction of soil moisture and consumptive use of water and reduction in water use efficiency were recorded with the increasing moisture regimes from CRI stage (I1) to 1.2 IW/CPE ratio (I5). The maximum water use efficiency of (166.6 kg ha-1cm-1) was obtained under moisture regime at CRI stage (I1) followed by irrigation at 0.6 IW/CPE (I2). The lowest water use efficiency (71.7 kg ha-1cm-1) was recorded under moisture regime at 1.2 IW/CPE ratio (I5).
