    (2024-03-22) Ram Sabha; Dr Lokendra Singh
    An Experiment was conducted in field plot during Kharif season, 2022 in the Old Dairy form of Chandra Shekhar Azad University of Agriculture & Technology, Kanpur entitled “Physiological Evaluation of Yield Differences in Hybrid Maize in Spring Season” Maize genotypes namely NK 7601, DKC 9108, DKC 9208, Pioneer 1899, Pioneer 3378, and Malik. were grown with four replications in field plots. Result obtained from experiment in respect of growth characters like plant height (cm), number of branches per plant, number of leaves per plant, leaf area per plant, CGR, NAR, RGR, SLW, total dry matter per plant and yield contributing character like number of pods per plant, number of grains per pod, number of grains per plant, 100 seed weight, and grain yield per plant. Significantly maximum plant height were recorded at harvest in genotypes NK 7601 followed by Malik and minimum plant height was recorded in genotype DKC 9208. In case of number of leaves per plant leaf area per plant and NAR value between 30 -- 60 DAS the genotypes NK-- 7601 and Malik recorded significantly higher value than other tested genotype. The genotype NK––7601 and Malik were produced significantly higher grain yield per plant among the tested genotype. These two varieties also recorded higher leaf area per plant NAR between 30--60 DAS and 60--90 DAS and also higher yield contributing character like, number of pods per plant, number of grains per plant, number of grains per pod, and grain yield per plant.

    (2023-08) Ashwani Kumar; Dr Sarvendra Kumar
    The present investigation entitled “Effect of date of sowing and varieties on growth and parameters in spring maize (Zea mays L.)” was carried out during Spring season of 2022 at Crop Physiology Farm, Chandra Shekhar Azad University of Agriculture and Technology, Kanpur. The field experiment included two factors, viz. dates of sowing (11th March & 1st April) and varieties (DKC-9248, DKC-9108, Pioneer- 3355, DKC-9208, Pioneer-1899) was laid out in split plot design and replicated four times. The date sowing on 11th March recorded better growth, yield attributes and grain yield (53.79 q/ha) and harvesting index (31.45%) of maize crop. Among maize varieties tested Vi3 DKC-9248 exhibited maximum grain yield (63.77q/ha) and harvest index (30.84 %) compared to other tested varieties. As regard physiological parameters sowing date on 11th March recorded maximum RGR at 60 to 90 days (40.37 mg/g/day). Among varieties respectively Pioneer-1899 recorded maximum RGR (40.63 mg/g/day).

    Effect of foliar application of Nano Urea and Boron on growth, and yield Parameters in wheat ( Triticum aestivum L.)
    Yadav, Sudhir Kumar; Khan, Dr.M.A.
    The experiment entitled: “Effect of foliar application of Nano Urea and Boron on growth, and yield Parameters in wheat (Triticum aestivum L.)” was conducted in the wire net house under pots during Rabi-season of the year 2021-22 in Department of Crop Physiology, C. S. Azad University of Agriculture and Technology Kanpur (UP), with aimed to study the Effect of foliar application of Nitrogen and boron on growth and yield Parameters in wheat (Triticum aestivum L). The wire net house under pot experiment comprises in 10 treatments viz. control (T1), Foliar spray of Nitrogen (nano urea) @2000ppm and Boron @0.2 kg ha-1(T2), Foliar spray Nitrogen (nano urea) @2000ppm and Boron @0.25 kg ha-1 (T3), Foliar spray of Nitrogen (nano urea) @2000ppm and Boron @0.3 kg ha-1 (T4), Foliar spray of Nitrogen (nano urea) @2500ppm and Boron @0.2 kg ha-1 (T5), Foliar spray of Nitrogen (nano urea) @2500ppm and Boron @0.25 kg ha-1 (T6), Foliar spray of Nitrogen (nano urea) @2500ppm and Boron @0.3 kg ha-1 (T7), Foliar spray of Nitrogen (nano urea) @3000ppm and Boron @0.2 kg ha-1 (T8), Foliar spray of Nitrogen (nano urea) @3000ppm and Boron @0.25 kg ha-1 (T9), Foliar spray of Nitrogen (nano urea) @3000ppm and Boron @0.3 kg ha-1 (T10). The result of the experiments has been on statistical analysis in order to comprise of different treatment and its effects on growth, and yield parameters and its components. The results obviously suggest and it may be concluded that foliar application of nitrogen and boron on wheat variety 1006 significantly change in growth, yield and yield attributes improvement in vegetative and reproductive growth for higher yield. these substances insidiously workout can be employed successfully for yield maximization of wheat crop. Growth characters plant height ,no of tillers, no of leaves, leaf area, chlorophyll intensity and total dry matter production were found to be maximum at foliar application of nitrogen 3000ppm and boron 0.3 kg/ha at 75 DAS . The yield attributes number of spikelet/ ear, number of grain/ear, weight grain/ plant, biological yield, grain yield/plant, harvest index % and test weight was found to be maximum at foliar application 3000ppm nitrogen and 0.3 kg/ha boron at 75 DAS on wheat crop for increase the production of wheat crop.

    Studies Of Foliar Application With Zinc And Iron On Growth, Yield And Quality Of Wheat (Triticum Aestivum L.) Under Normal And Late Sown Conditions
    Singh, Madhukar; Singh, O P
    The field experiments were conducted at Student’s Instructional Farm, of Chandra Shekhar Azad University of Agriculture and Technology, Kanpur (U.P.) India, during Rabi seasons i.e. 2017-18 and 2018-19. The objectives of investigation were to “Studies of foliar application with zinc and iron on growth, yield and quality of Wheat (Triticum aestivum L.) under normal and late sown conditions”. It was designed in split plot design with three replications. The two date of sowing i.e. timely (D1) and late sown (D2) conditions were allocated in the main plots and in sub plot that significantly higher yield (kg/ha), (4951 and 5110) significant higher with normal sown condition with both years, Foliar spray application of zinc 200 ppm showed significantly better response both years i.e. (4852 and 5008) and iron level 200 ppm given statistically best response i.e. (4823 and 4978) compare to control. The same results were recorded with morphological traits, physiological traits, phonological traits and biochemical traits. Traits like grain growth rate, number of grain per spike, test weight, harvest index, zinc content in grain, iron content in grain and protein content exhibit same results enhancing to get higher grain yield of wheat with both concerning experimental years.

    Effect of plant growth regulators on morpho-physiological parameters and yield of wheat (Triticum aestivum L.) Under late sown condition
    Singh, Mayanker; Kushwaha, S P
    The present investigation entitled “Effect of plant growth regulators on morpho- physiological parameters and yield of wheat (Triticum aestivum L.) under late sown condition” has been taken to focus the involvement and potential role of plant growth regulator and was carried out in during 2019-20 and 2020-21 at Agronomy Research Farm of C.S.A. University of Agriculture and Technology, Kanpur (U.P.) has been taken to focus the involvement and potential role of plant growth regulators in plant responses to late sown condition. The experiment was laid out using randomized block design with eleven distinct treatments with three replications using variety ‘Unnat Halna (K-9423) with line to line spacing of 30 cm and row to row 20 cm. The soil of the experiment was silty-loam in texture and alkaline in reaction having less nitrogen, phosphorous and potassium. The experiment was done in Randomised block design with three replications and eleven treatments. The wheat variety K-9423 was taken as a test crop and the seeds were planted in line 20 cm and plants 15 cm. in month of 20 November, 2017 and 19 November,2018. The crop was fertilized with recommended doses of fertilizers viz., 120 kg N kg/ha, 60 kg P2O5/ha, 60 Kg K2O/ha during both the years of the investigation. Among the plant growth regulator i.e., auxins play an important role in hormonal activity for flower production in plants. Indole Acetic Acid (IAA) is one of the most growth promoting hormones, may play significant role to change growth character and yield in wheat. IAA plays a major role on regulation of plant growth for instance, it controls vascular tissue development, cell elongation, and apical dominance (Wang et al., 2001) and IAA stimulates cell elongation by modifying certain conditions like, increase in osmotic contents of the cell, increase in permeability of water in to cell, decrease in wall pressure, an increase in cell wall synthesis, protein synthesis and actively participates in adaptive responses of the plant to different stress factors
