ThesisItem Open Access Effect of microclimate on growth and yield of strawberry intercropping with chilli under open and controlled environments(CCSHAU, 2019) Suresh; Ram NiwasThe field investigations on “Study on Effect of microclimate on growth and yield of strawberry intercropping with chilli under open and controlled environments” was carried out under greenhouse and open field during winter of 2018-19 at Precision farming development centre, Department of Horticulture, Gate no. 3, Chaudhary Charan Singh Haryana Agricultural University, Hisar, during Rabi season 2018-19. The treatments consisted of five treatments sole strawberry (SS), sole chilli (SC), 1 chilli one strawberry row (1C1S), 1 chilli 2 strawberry rows (1C2S), and 1 chilli 3 strawberry rows (1C3S). The twenty combinations were evaluated in randomized block design under open field conditions and twenty combinations were evaluated in completely randomized design under greenhouse conditions. The highest thermal and radiation indices in 1 chilli 3 strawberry rows (1C3S) treatment as compared to other treatments under both conditions. But HUE and RUE were higher in chilli crop in 1 chilli 3 strawberry rows (1C3S) treatment as compared to other treatments under both conditions. When growing parameters were compared, it was found that crop planted inside the greenhouse was superior in all aspects including yield parameters. Among strawberry, chilli and their intercropping treatments 1chill three strawberry rows (1C3S) consumed highest heat units, heliothermal units and photothermal units as compared to other treatments under open and greenhouse field conditions. HUE, RUE and yield parameters were highest in chilli crop in 1C3S treatment in greenhouse conditions. LAI was maximum at 90 DAP and dry matter at maturity under both conditions. Also, 1chilli 3 row strawberry (1C3S) treatment was proved to be superior in both open and greenhouse field conditions. The correlation and regression analysis were carried out to study the relationship between yields attributes and microclimate of strawberry, chilli and their intercrops in all treatments. Most of the yield parameters were positively correlated with maximum temperature and non-significant negative correlation with morning relative humidity.ThesisItem Open Access Genotypic variability in core collection of bread wheat genotypes for drought and heat tolerance(CCSHAU, Hisar, 2021-06) Suresh; Solanki, Y.P.S.The demand of wheat is expected to increase due to population explosion but climatic factors such as drought and heat stress are causing serious threat to wheat production. Availability of genetic variability along with knowledge of yield attributing traits is helpful in breeding wheat genotypes for these stressed conditions. The present investigation was therefore, carried out to study the genetic variability for yield and attributing morphological traits, identification of traits which can be used for indirect selection and validation of SSR markers associated with combined stress of heat and drought. With this regard forty wheat genotypes were evaluated under four sowing conditions at Research Area, Wheat and Barley Section, Department of Genetics and Plant Breeding, CCS HAU, Hisar during rabi 2018-19 and 2019-20. Significant genetic variability was observed for all the morphological and physiological traits. Correlation and path analysis revealed that biological yield, harvest index, thousand grain weight, SPAD, NDVI and chlorophyll fluorescence reading were associated with grain yield and had direct or indirect effect on grain yield. Stress indices revealed that genotypes NIAW 3170, PBW 676, HD 3298, HD 3217, WH 1202, WH 1164, PBW 773, HD 1621 and WH 1142 were found tolerant to restricted water stress condition. Similarly genotypes HD 3237, WH 1124, DBW 252, WR 544, HD 3043, HD 3226, HD 3298, HI 1623, DBW 278 and WH 1202 were found tolerant to high temperature. Genotypes HD 3237, HI1623, NIAW 3170, WH 1202, HD 1621, HD 3226 and DBW 278 were found stable for dual stress conditions. Cluster analysis grouped the forty genotypes into 5 clusters and revealed that these genotypes were highly divergent. Similarly significant genetic diversity was noted based on 12 polymorphic SSR markers. Out of 12 polymorphic SSR primers, WMC 24, GWM 374, WMC 661, GWM 247, GWM 6, GWM 186, GWM 335 and GWM 508 were found associated with both drought and heat tolerance.ThesisItem Open Access Genotypic variability in wheat and triticale for grain yield and its components under normal and late sown conditions(CCSHAU, 2017) Suresh; Bishnoi, O.P.The objectives of present investigation were to determine the genetic variability, estimation of association between grain yield and its component traits and among themselves to find out the correlation with agro-meteorological parameters of 28 genotypes of wheat and triticale under two dates of sowing. Significant variability was observed among genotypes for all the traits under both the environments. Genotypes WH1105, WH1142, HD 3086, WHD 948 and TL 3004 have been found promising for grain yield under favorable environment. Grain yield per plant showed highly significantly and positive phenotypic correlation with biological yield per plant, harvest index, number of grains per spike and 1000-grain weight. The path coefficient analysis revealed that Biological yield per plant registered the highest direct and positive effects on grain yield per plant followed by harvest index. Nutrient uptake and use efficiency was higher in triticale and synthetic wheat under late sown conditions. Triticale and synthetic have a low value of HSI showing its low susceptibility to elevated temperature which can be utilized in heat tolerance breeding programme.ThesisItem Open Access Influence of integrated crop management practices on the performance of field pea (Pisum sativum L.)(G.B. Pant University of Agriculture and Technology, Pantnagar - 263145 (Uttarakhand), 2015-01) Suresh; Singh, V.K.A field experiment was conducted during rabi season of 2013-14 at Norman E. Borlaug Crop Research Centre (CRC) of G. B. Pant University of Agriculture & Technology, Pantnagar, to study the effect of different integrated crop management practices on growth and development, yield and quality of field pea. The soil of the experimental plot was sandy loam in texture, having medium organic carbon (0.57%), available nitrogen (286.9 kg N /ha), available phosphorus (16.1 kg P/ha) and available potassium (251.1 kg K/ha) contents with neutral pH (7.4). The experiment consisted of eight crop management practices viz. control, INM (Integrated Nutrient Management): (RDF [Recommended Dose of Fertilizer (18:48:24 kg N, P2O5& K2O/ha)] + seed inoculation with Rhizobium + PSB [Phosphorus Solubilizing Bacteria (KB-133)] @ 20 g/kg seed each), IWM (Integrated Weed Management): (Pendimethalin @ 1.0 kg/ha. + 1 hand weeding, 30 DAS), IPM (Integrated Pest Management): (Seed treatment with fungicide + disease and insect-pest management as and when required), INM + IWM, INM + IPM, IWM + IPM, INM +IWM + IPM was laid out in randomized block design (RBD) with three replications. Pant P. 14 variety of field was sown on October 29, 2013, 30 cm apart and harvested on March 21, 2014. Culture operations were followed as per treatment. Results revealed that growth attributes viz.; effective control of weeds (in terms of population and dry weight) was achieved by INM+IWM+IPM practices, number of branches and dry matter accumulation of field pea was higher under INM +IWM + IPM than control. Integration of INM+IWM+IPM practices increased the number of pods per plant, grain weight per plant, straw yield, biological yield, grain: straw ratio and harvest index significantly over control. This practice, being at par with that of INM+IWM recorded significantly higher field pea grain yield over control. N, P and K contents in grain and straw and protein content in grains were not influenced significantly by different integrated crop management practices. A significant increase in N, P and K uptake by crop and protein yield was noticed under combined use of nutrient, weed and pest management practices than (INM+IWM+IPM) those of control and remaining treatments.ThesisItem Open Access STUDIES ON LEAF BLIGHT OF SUNFLOWER (Helianthus annuus L.)
