    INFLUENCE OF POTASSIUM AND NICKEL NUTRITION ON WATER STATUS, BIOMASS PRODUCTION AND YIELD IN MAIZE UNDER HEAT STRESS
    (Acharya N G Ranga Agricultural University, Guntur, 2019) GOWTHAMI, P; ASHOKA RANI, Y
    A study entitled influence of potassium and nickel nutrition on water status, biomass production and yield in maize under heat stress was carried out at Agricultural College Farm, Bapatla during rabi 2017-18 and 2018-19 in split plot design, with three dates of sowing (December 20, January 10 and January 30) as main plots and eight treatments viz., S1: 100% RDK (Control); S2: 125% RDK; S3: 1 kg Ni ha-1; S4: 2 kg Ni ha-1; S5: S1+S3; S6: S1+S4; S7: S2+S3; and S8: S2+S4 as subplots in three replications. From the findings of the experiment it was revealed that increased mean maximum and minimum temperatures creates a heat stress for late sown crops resulting in significant influence on growth, biomass production, water status, leaf associated parameters, biochemical parameters, yield and yield components. Application of potassium and nickel also significantly affected the recorded parameters. Plant height was reduced by 14.7 to 24.6 per cent during 2017-18 and 9.6 to 20.7 per cent during 2018-19 in late sown crops whereas application of potassium and nickel enhanced the plant height by 6.7 to 33.6 per cent during 2017-18 and 5.6 to 28.2 per cent during 2018-19. During both the years, reduction in leaf area due to heat stress ranged from 7.9 to 17.1 per cent and 9.4 to 16.4 per cent respectively and an enhancement of 7.4 to 35.2 per cent and 7.8 to 38.3 per cent respectively was recorded with nutrient treatments. December 20 sown crop had taken maximum number of days to 50 per cent tasseling and minimum for 50 per cent silking. In January 30 sown crop it was observed that 50 per cent tasseling was hastened and silking was delayed. xviii Application of potassium and nickel enhanced the days to 50 per cent tasseling and reduced the days to 50 per cent silking resulting in reduced anthesis silking interval. Drymatter partitioning and total drymatter was greatly influenced by dates of sowing, potassium and nickel application. Higher leaf drymatter was observed at 60 DAS with a reduction of 10.7 to 24.1 per cent during 2017-18 and 10.2 to 22.5 per cent during 2018-19 due to heat stress under delayed sowing. Application of potassium and nickel enhanced the leaf drymatter to an extent of 4.4 to 21.7 per cent during 2017-18 and 1.9 to 20.4 per cent during 2018-19. Stem drymatter was reduced by 9.0 to 18.9 per cent during 2017-18 and 4.1 to 8.1 per cent during 2018-19 due to heat stress in late sown crops. The application of potassium and nickel increased it from 4.3 to 20.9 per cent during 2017-18 and 5.3 to 21.0 per cent during 2018-19. Reduction in root drymatter under delayed sowing ranged from 12.0 to 24.7 per cent during 2017-18 and 9.0 to 20.6 per cent during 2018-19. The increment with potassium and nickel application ranged from 6.8 to 33.6 per cent during 2017-18 and 3.4 to 22.6 per cent during 2018-19. Reproductive parts drymatter reduced to an extent of 5.6 to 13.3 per cent during 2017-18 and 4.7 to 8.2 per cent during 2018-19 due to heat stress under delayed sowing and with potassium and nickel application it was enhanced by 6.5 to 30.9 percent during 2017-18 and 4.4 to 23.1 per cent during 2018-19. During both the years a reduction of 8.3 to 18.4 per cent and 6.6 to 11.9 per cent was recorded in TDM due to the increased temperatures with delayed sowing and an increment of 6.5 to 31.5 per cent and 4.9 to 24.6 per cent was obtained with the application of potassium and nickel. Heat stress under delayed sowing resulted in 4 to 10.8 percent reduction in RWC. Potassium and nickel application increased the leaf water status and restored the normal conditions. Soil and canopy temperature were increased with increased temperature. Hence higher temperatures were recorded in M3 and application of potassium and nickel reduced the temperatures with the lowest values recorded in S8. Photosynthetic rate was declined by 5.5 to 11.1 and 4.5 to 9.0 m mol CO2 m-2 s-1 during 2017-18 and 2018-19 respectively due to heat stress induced by delayed sowing. An enhancement of 1.9 to 9.5 and 1.7 to 10.9 m mol CO2 m-2 s-1 during 2017-18 and 2018-19 respectively was observed with potassium and nickel application. Similarly stomatal conductance, internal CO2 and transpiration rate were also reduced with high temperatures and enhanced to some extent with nutrient treatments. xix Delayed sowing resulted in reduction of CSI to an extent of 6.1 to 14.2 percent due to increased temperatures. Potassium and nickel application enhanced the CSI by 3.7 to 19.3 per cent. An enhancement in MII (7.4 to 14.7 %) was observed in late sown crops with the increased temperatures, whereas with the application of potassium and nickel MII decreased by 2.5 to 13.5 per cent. Proline content was increased with enhanced temperatures by 11.6 to 20.7 percent during 2017-18 and 13.3 to 20.8 per cent during 2018-19. Potassium and nickel increased the proline content by 3.7 to 17.6 per cent and 2.7 to 18.3 per cent during 2017-18 and 2018-19 respectively. Enhanced activity of SOD (0.4 to 1.0 U mg-1 protein) and peroxidase (2.6 to 8.5 U mg-1 protein) was observed in late sown crops with the raise in temperatures. Application of potassium and nickel also increased the SOD and peroxidase activity. Yield components as number of rows per cob, number of kernels per row, test weight except number of cobs per plant were significantly reduced with increased temperatures in late sown crops and enhanced to some extent by potassium and nickel application, resulting in yield reduction by 18.0 to 50.2 per cent during 2017-18 and 16.6 to 48.8 per cent during 2018-19 and increment among the nutrient treatments except in S3 and S4 by 6.6 to 30.0 per cent during 2017-18 and 6.2 to 28.4 per cent during 2018-19. HUE was lowered by 18.7 to 48.8 per cent during 2017-18 and 18.0 to 47.5 per cent during 2018-19 in late sown crops indicating M1 produced greater yield per each heat unit absorbed. Nutrient treatments enhanced it by 6.6 to 30.2 per cent during 2017-18 and 6.0 to 28.3 per cent during 2018-19. Among the yield based stress indices except SSI all other as RHI, STI, GMP, MP and YSI were more in M2 than M3. Among the potassium and nickel all other treatments except S3 and S4 enhanced the stress indices with the highest values in S8 and S3 the lowest with high SSI.

    EFFECT OF FOLIAR APPLICATION OF POTASSIUM, BORON AND ZINC ON GROWTH AND YIELD OF SOYBEAN (Glycine max (L.) Merrill)
    (ACHARYA N.G. RANGA AGRICULTURAL UNIVERSITY, GUNTUR, 2014) GOWTHAMI, P; RAMA RAO, G
    A field experiment was carried out at the Agricultural College Farm, Agricultural College, Bapatla during kharif 2013-14 to study the effect of foliar application of potassium, boron and zinc on growth and yield of soybean (Glycine max (L.) Merrill).The experiment was laid out in randomized block design with eight treatments imposed at 30 and 60 DAS viz., potassium nitrate @ 2 per cent (T1), boric acid @ 50 ppm (T2), zinc sulphate @ 1 per cent (T3), potassium nitrate @ 2 per cent + boric acid @ 50 ppm (T4), potassium nitrate @ 2 per cent + zinc sulphate @ 1 per cent (T5), boric acid @ 50 ppm + zinc sulphate @ 1 per cent (T6), potassium nitrate @ 2 per cent + boric acid @ 50 ppm + zinc sulphate @ 1 per cent (T7) and Control (T8) in three replications. The findings of the experiment revealed that the growth parameters such as plant height, number of branches, number of leaves, leaf area and total drymatter measured at different intervals were greatly influenced by potassium, boron and zinc treatments. Spray of potassium nitrate @ 2 per cent + boric acid @ 50 ppm + zinc sulphate @ 1 per cent at 30 and 60 DAS (T7) was found to be superior, resulting in an increase of 28.5 per cent in plant height, 29.16 per cent of number of leaves and 30.13 per cent in number of branches. It was followed by potassium nitrate @ 2 per cent + boric acid @ 50 ppm at 30 and 60 DAS (T4) which produce an increase of 14.92 per cent in plant height, 27.02 per cent in number of branches and 20.84 per cent in number of leaves over control. The spray of potassium nitrate @ 2 per cent + boric acid @ 50 ppm + zinc sulphate @ 1 per cent at 30 and 60 DAS (T7) enhanced the leaf area by 37.14 per cent over control, followed by potassium nitrate @ 2 per cent + boric acid @ 50 ppm (T4) at 30 and 60 DAS (32.61 % higher over control). Growth parameters i.e., CGR, RGR, NAR, LAI, SLA, SLW, LAD and LAR were also greatly influenced by the foliar sprays and better performance was obtained with potassium nitrate @ 2 per cent + boric acid @ 50 ppm + zinc sulphate @ 1 per cent at 30 and 60 DAS (T7). Biochemical parameters like total chlorophyll, protein and oil contents were increased with foliar spray compared to control and higher values were obtained in the treatment potassium nitrate @ 2 per cent + boric acid @ 50 ppm + zinc sulphate @ 1 per cent at 30 and 60 DAS (T7) followed by potassium nitrate @ 2 per cent + boric acid @ 50 ppm at 30 and 60 DAS (T4), boric acid @ 50 ppm + zinc sulphate @ 1 per cent at 30 and 60 DAS (T6) and potassium nitrate @ 2 per cent + zinc sulphate @ 1 per cent at 30 and 60 DAS (T5). The spray of potassium nitrate @ 2 per cent + boric acid @ 50 ppm + zinc sulphate @ 1 per cent (T7) at 30 and 60 DAS increased the test weight by 28.82 per cent and seed yield by 28.59 per cent over control, and all other treatments increased seed yield to an extent of 5.15 to 20.91 per cent over control. From the findings of the experiment it was concluded that the foliar application of potassium nitrate @ 2 per cent + boric acid @ 50 ppm + zinc sulphate @ 1 per cent at 30 and 60 DAS showed a better performance in improving the growth and productivity of soybean.
