ThesisItem Open Access Compensating nitrogen fertilizer requirement of desi wheat through Azotobacter and vermicompost(CCSHAU, 2019) Fazal Rabi; Sewhag, MeenaThe present study entitled, “Compensating nitrogen fertilizer requirement of desi wheat through Azotobacter and vermicompost” was conducted during the rabi season of 2017-2018 at the Agronomy Research Farm of Chaudhary Charan Singh Haryana Agricultural University, Hisar to study the effect of Azotobacter and vermicompost on growth, yield, quality and economics of desi wheat. The soil of the experimental field is sandy loam in texture, slightly alkaline in reaction, low in organic carbon and nitrogen, medium in available phosphorus and potassium. The experiment was laid out in Randomized Block Design replicated thrice with ten treatments viz. T1 (Control) , T2 (Vermicompost @ 6 t ha-1) , T3 (Azotobacter + Vermicompost @ 6 t ha-1), T4 (30 kg N ha-1 + Vermicompost @ 3 t ha-1), T5 (40 kg N ha-1 + Vermicompost @ 2 t ha-1), T6 (50 kg N ha-1 + Vermicompost @ 1 t ha-1), T7 (30 kg N ha-1 + Azotobacter + Vermicompost @ 3 t ha-1), T8 (40 kg N ha-1 + Azotobacter + Vermicompost @ 2 t ha-1), T9 (50 kg N ha-1 + Azotobacter + Vermicompost @ 1 t ha-1) and T10 (60 kg N ha-1). Among various combinations of nitrogen fertilizer, vermicompost and Azotobacter treatments ,T10 recorded significantly higher growth parameters viz. [plant height (cm), LAI and dry matter accumulation/plant], yield attributing characters [Number of grains per spike, number of spikelets per spike and spike length (cm) ] , grain, straw and biological yield , protein content, N, P and K content and uptake in grain and straw, total N, P and K uptake, gross returns, net returns and benefit: cost ratio of desi wheat. However, in terms of growth, yield, nutrient studies, quality and economics in treatment T9 and T8 were at par with treatment T10. But various treatments failed to produce any significant variation in days taken to seedling emergence, panicle initiation and anthesis, plant population at 15 DAS, 1000 grain weight and harvest index.ThesisItem Open Access Effect of sowing time and seed rate on growth and yield of chickpea cultivars(CCSHAU, 2014) Sethi, Indu Bala; Sewhag, MeenaA f ield exper iment e ntitled ìEffect of sowing time and seed rate on growth and yield of chickpea cultivarsî was conducted dur ing rabi 2012-13 at Pulse Researc h Area of CCS Hary ana Agricultural University , Hisar . The exper ime nt was laid out in a split plot design with two sowing time (1 st for tnight of November and 1 st for tnight of December ) and four cultivars (H09-23, H08-18, C-235 and HC-1) kept in main plots while three seed rates viz . 40 kg ha - 1 , 50 kg ha -1 and 60 kg ha - 1 were kept in subplots and replicated thrice. Based on the research investigatio n it was found that c hickpea sown on 1 st for tnight of November produced better growth, y ield attr ibutes (except100 grain weight) , y ield, total N, P and K uptake, grain protein content, nodule number and its dry weight, gross returns , net returns and BC ratio. But, harvest index, N content in stover , P and K conte nt in grain and stover y ield unde r both the time of sowing did not dif fer signif icantly . Various chickpea cultivar failed to inf lue nce plant population, grains per pod, stover y ield, bi ological y ield, harvest index and N, P and K content and uptake in stover , N, P and K content in grain , total P and K uptake and protein content in stover and grain. Plant height and dry matte r accumulation was better in cultivar H09-23 than rest all cultivars (H08-18, C235, and HC-1).While, highest gross returns , net re turns and BC ratio was recorded with H08-18 which dif fered signif icantly f rom HC-1 and C235 but, was statistically at par with H09-23. Seed rate of 50 kg ha -1 produced maximum number of grains pe r pod, N conte nt and uptake in grain, P uptake by grain, total P uptake , protein conte nt in grain and BC ratio. However , highest plant population, stover and biological y i eld were observed with seed rate of 60 kg ha -1 and highest number of pods per plant and harvest index with seed rate of 40 kg ha -1 . Vary ing seed rates failed to inf luence plant height, dry matter production, 100 grain weight, nodulation and N,P,K and protein content, net and gross returns , However signif icantly highe r grain y ield was obtained with 50 kg ha -1 seed rate as compared to 60 kg ha -1 .ThesisItem Open Access Effect Of Moisture Regimes In Clusterbean-Wheat Crop Sequence Planted On Raised Beds(Chaudhary Charan Singh Haryana Agricultural University; Hisar, 2005) Sewhag, Meena; Hooda, I.S.ThesisItem Open Access Integrated Nutrient Management in Barley(CCSHAU, 2019) Sandeep Kumar; Sewhag, MeenaThe present study entitled, “Integrated nutrient management in barley” was conducted during the Rabi season of 2017-2018 at the Agronomy Research Farm of Chaudhary Charan Singh Haryana Agricultural University, Hisar with the objective to study the effect of different nutrient management practices on growth, yield, quality and economics of barley. The experiment was laid out in Randomized Block Design replicated thrice with ten different treatments viz. T1(Control) , T2 (Biomix) , T3 (Vermicompost @ 5 t ha-1), T4 ( Biomix + Vermicompost @ 5 t ha-1), T5 (50 % RDN + Vermicompost @ 5 t ha-1), T6 (75 % RDN + Vermicompost @ 5 t ha-1), T7 (50% RDN + Biomix + Vermicompost @ 5 t ha-1), T8 (75 % RDN + Biomix+ Vermicompost @ 5 t ha-1), T9 (RDN) and T10 (RDN + Biomix + Vermicompost @ 5 t ha-1). Among nutrient management practices treatments T10 recorded significantly higher growth parameters viz. [plant height (cm), LAI, number of tillers / m.r.l. and dry matter accumulation/plant (g/plant)], yield attributing characters [Number of grains per spike and spike length (cm) ] , grain, straw and biological yield (kg ha-1), protein content, N, P and K content in grain and straw (except K content in straw), gross returns, net returns and benefit: cost ratio of barley. Performance in terms of growth, yield, nutrient studies, quality and economics of barley in treatment T8 (75 % RDN + Biomix+ Vermicompost @ 5t ha-1) was at par with treatment T9 (RDN) and T10 (RDN + Biomix + Vermicompost @ 5t ha-1). Treatment T10 took highest number of days to flag leaf emergence, booting, anthesis and maturity as compared to other treatments. Treatment T1 being at par with treatment T2 recorded significantly higher value of malt content of barley than treatment T3 to T10. But various combinations of nitrogen fertilizer, biomix and vermicompost failed to produce any significant variation in days taken to emergence and tillering, plant population at 20 DAS, test weight, harvest and attraction index, quality parameters like hectoliter weight and boldness as well as thinness of barley grain, K content (%) in straw and available N, P and K status of soil after the harvest of barley.ThesisItem Open Access Performance of different pearl millet hybrids as influenced by Biomix inoculation and chemical fertilizers(CCSHAU, 2017) Yamank; Sewhag, MeenaA field experiment entitled “Performance of different pearl millet hybrids as influenced by Biomix inoculation and chemical fertilizers” was conducted during kharif 2016 at Agronomy Research Area of CCS Haryana Agricultural University, Hisar. The experiment was conducted in split plot design keeping three replications with the treatments consisting of six fertility management (Control, Biomix, 75 % RDF, RDF,75% RDF + Biomix and RDF + Biomix) and three hybrids ( HHB 234, HHB197 and HHB 223). Based on the research investigation it was found that treatment F6 (RDF + Biomix), being at par with treatment F5 (75% RDF + Biomix ) produced better growth, yield attributes (except number of earhead plant-1), yield, total N, P and K uptake, grain protein content and yield, gross returns, net returns and B:C. But, phenological stages, plant population at 20 DAS and at harvest, dry matter accumulation per plant at 40 DAS to 60 DAS, numbers of tillers plant-1 at 30 DAS and at harvest, tiller conservation index, harvest and attraction index, K content in grain and stover of pearlmillet hybrid under various combinations of RDF and Biomix inoculation did not differ significantly. Among different pearl millet hybrid, significantly taller plants at all the growth stages; longer earhead, higher dry matter accumulation, 1000 grain weight, grain yield, stover yield, biological yield, harvest index ,attraction index, protein yield, K uptake in grain and stover ,gross returns, net return and B: C were obtained in hybrid HHB 223. The difference between the hybrid HHB 197 and HHB 234 for stover and biological yield were however, not significant. Various pearlmillet hybrids did not markedly influence days taken to emergence, five leaf stage, panicle initiation, flag leaf stage and boot stage, plant population at 20 DAS and at harvest, numbers of tillers plant-1, number of earhead plant-1, tiller conservation index, N content in stover and N uptake in grain and P content in grain and stover.Non significant interaction between various combinations of RDF and Biomix inoculation and different hybrids on the grain and stover yield of pearlmillet were observed.ThesisItem Open Access Relative performance of barley (Hordeum vulgare L.) cultivars under different date of sowing(CCSHAU, 2015) Chaudhary, Ankur; Sewhag, MeenaA field experiment entitled “Relative performance of barley (Hordeum vulgare L.) cultivars under different date of sowing” was conducted during rabi 2013-14 at Wheat and Barley Research Area of CCS Haryana Agricultural University, Hisar. The experiment was laid out in a split plot design with five date of sowing (30 th October, 10 th , 20th, 30th November and 10 th December) in main plots and four cultivars (BH 902, RD 2552, RD 2668 and DWRUB 52) kept in sub plots replicated thrice. Based on the research investigation it was found that growth parameter of barley viz, plant height, dry matter, LAI and number of tillers decreased significantly with delay in sowing .Crop sown on 30 th October produced significantly higher values of growth parameters but it was statistically at par with 10 th November sowing date. Yield attributes, yield and quality parameters (Grain protein content, hectoliter weight and bold grain percentage) were reduced significantly as the sowing was delayed from 10 th November to 10 th December. While, reverse trend was observed in thin grain percentage and malt content of barley cultivars. Date of sowing fails to influence harvest and attraction index of barley cultivars. Among the various barley cultivars, RD2552 took significantly less number of days to all phenophases (except emergence) as compared to other cultivars. Significantly taller plants and higher dry matter accumulation at all the crop growth stages were recorded in cultivar BH 902 followed by RD 2552. Maximum number of tillers was recorded in cultivar DWRUB 52 and LAI in cultivar BH 902 at all the stages of crop growth. Barley cultivar DWRUB 52 being at par with BH 902 produced significantly longer spikes, test weight and grain yield than other cultivars (RD 2552 and RD 2668). Cultivar BH 902 produced higher number of grains per spike, straw and biological yield which was significantly higher from other cultivars except RD 2552. Barley cultivar DWRUB 52 recorded significantly higher value of harvest and attraction index as compared to other cultivars. Barley cultivars RD 2552 and DWRUB 52 showed superiority in protein content as compared to other two cultivars (BH 902 and RD 2668). Cultivar DWRUB 52 recorded significantly higher hectoliter weight of barley as compared to other three cultivars (BH 902, RD2552 and RD 2668). Maximum bold grains percentage was found in cultivar BH 902 and it was significantly higher as compared to other cultivars except DWRUB 52, while, thin grain percentage was recorded highest in cultivar RD 2552.ThesisItem Open Access Respones of Rainfed Pearlillet [Pennisetum Glaucum (L.) R. Br. emend. Stuntz) Composite to Nitrogen(College of Agriculture Chaudhary Charan Singh Haryana Agricultural University Hisar, 1981) Sewhag, Meena; Singh, HarbirThesisItem Open Access Response of barley to fertilizer levels and different combinations of biofertilizers(CCSHAU, 2018) Malik, Priti; Sewhag, MeenaThe present study entitled, “Response of barley to fertilizer levels and different combinations of biofertilizers” was conducted during the Rabi season of 2015-16 and 2016-17 at the Agronomy research farm of Chaudhary Charan Singh Haryana Agricultural University, Hisar .The experiment was laid out in split plot design with three fertilizer levels (50, 75 and 100 per cent RDF) in main plots and seven different combinations of biofertilizers (Uninoculated, seed inoculation with Azotobacter, Azospirillum, PSB, Biomix, Azotobacter+PSB and Azospirillum+PSB) in sub plots replicated thrice. Based on the research investigation it was found that significantly taller plants, higher dry matter production and Leaf area index were recorded with the application of 100 % RDF than lower fertilizer levels (50 and 75 % RDF). Increasing levels of fertilizer resulted in significant higher yield attributes (number of spikes per meter row length, more number of grains per spike and test weight) and yield (grain, straw and biological yield) of barley. However, plant population, harvest and attraction index, quality parameters (Proportion of thin and bold grains percentage and hectoliter weight), canopy temperature of barley and available nutrient status of soil (N, P and K) after the harvest of barley were statistically similar under all the fertilizer levels. While malt content of barley decreased significantly with increase in fertilizer levels during both the years of experimentation. Application of 100 % RDF recorded significantly higher protein content, NDVI value of barley, N content and N, P and K uptake in grain and straw, net returns, gross returns and benefit: cost ratio than the lower fertilizer levels (50 and 75 % RDF). Among different combinations of biofertilizers, seed inoculation with Biomix recorded significantly higher plant height, dry matter accumulation, LAI, all the yield attributes (number of spikes per meter row length, number of grains per spike and test weight), grain, straw, biological yield, protein content, N content in grain , P content in grain in the year 2015-16, N, P and K uptake in grain and straw, higher gross returns, net returns and benefit: cost ratio of barley during both the years of experimentation . But harvest index, proportion of thin and bold grains percentage, hectoliter weight, malt content, canopy temperature, NDVI value of barley, P content in grain in 2016-17 and K content in grain and N, P and K content in straw and available N, P and K status of soil after the harvest of barley did not differ significantly due to seed inoculation with different combinations of biofertilizers during both the years of experimentation. Seed inoculation with Biomix in association with 75 % RDF was found to be significantly superior in terms of grain and straw yield of barley.ThesisItem Open Access Response of Bt cotton (Gossypium hirsutum L.) to the foliar spray of nutrients(CCSHAU, Hisar, 2023-01) Kalu Ram; Sewhag, MeenaThe present investigation entitled “Response of Bt cotton (Gossypium hirsutum L.) to the foliar spray of nutrients” was carried out during crop season kharif 2021-22 at Cotton Research Area of Chaudhary Charan Singh Haryana Agricultural University, Hisar. The experiment was laid out in Randomized Block Design replicated thrice with eight treatments of foliar application of nutrients viz. T1: Control, T2:MgSO4 (0.5%), T3:ZnSO4 (0.5%), T4:FeSO4 (0.5%), T5: Borax (0.5%), T6:ZnSO4 (0.5%) +Urea (2%), T7: DAP (1%), T8: Urea (2%) applied at 60, 75, 90 DAS. The results revealed that days to 50 % flowering were significantly less in T8 which was at par with treatment T3, T5, T6 and T7, while treatment T5 recorded lowest number of days to 50% boll formation. Plant height at 75, 105, 135 DAS and harvest was recorded significantly higher in treatment T2 which was at par with T6. At 75 DAS, treatment T3 being at par with T2 and T5 resulted in significantly higher dry matter accumulation than rest all foliar sprays of nutrients. At 105 and 135 DAS treatment T6 being at par with T2,T3,T4 and T5 recorded significantly higher dry matter accumulation than rest all foliar sprays of nutrients. At harvest treatment T2 being at par with T3,T4,T5, T6 T7 and T8 recorded significantly higher dry matter accumulation than control treatment while T6 being at par with T2,T3 , T5 and T8 produced significantly more number of bolls per plant (45) than T1, T4 andT7 .Highest seed cotton yield was recorded in treatment T6(ZnSO4 (0.5%) +Urea (2%) which was significantly superior to T4 and T1 (Control) but at par with rest all treatments (T2, T3, T4, T5, T7 and T8). Boll weight (g) of Bt cottonwas highest in treatment T2 which differ significantly over other treatments except T5, T6, T7 and T8. Highest seed index (8.98 g) was recorded in treatment T7 followed by T8 (8.74 g) and T6 (8.73 g). (T6) being at par with T5 and T8 produced significantly higher value of ginning out turn (38.9%) than rest all treatments. Highest net returns were found with the treatment T2. The B:C was highest (2.47) in T2. The highest gross returns were found with the treatment T6ThesisItem Open Access Status and evaluation of herbicide resistance in Rumex dentatus L. and its management in wheat(CCSHAU, Hisar, 2020-12) Dahiya, Seema; Sewhag, MeenaHerbicide resistance in Rumex dentatus in wheat could be a major sustainability issue, which can put the rice-wheat cropping system (RWCS) in IGP under serious threat. The investigation entitled “Status and evaluation of herbicide resistance in Rumex dentatus L. and its management in wheat” comprising of a wellstructured survey carried out during rabi season of 2018-19 (end of January to February 2019), a pot bioassay study conducted at screen house, CCS HAU Regional Research Station, Karnal during rabi season of 2018-19 and a two year field experiment, carried out during rabi seasons of 2017-18 and 2018-19 at KVK, Panipat. The survey was conducted in three districts (Panipat, Karnal and Kurukshetra) of Haryana. Two blocks were selected from each district and two villages from each block and a total number of 120 farmers were covered from 12 villages involving 10 farmers from each village. The diagnostic survey in three districts of Haryana indicating that the use of metsulfuron-methyl is decreasing over the years from 61.1% in 2016-17 to 23.8% in 2018-19 and that of metribuzin is increasing from 6.49% in 2016-17 to 41.27% in 2018-19. Majority of farmers apply herbicide for control of R. dentatus during 35- 35 DAS. More than 80% farmers use flood jet/ cut nozzle instead of using recommended flat fan nozzle by only 19% of total farmers. Almost all farmers have heard about herbicide resistance (99.9%) and they follow herbicide rotation (85.8%) after an average of 2.04 years. Spraying was done mostly by hired labor (70.3%) but in the presence of farmers. Around 75% farmers do not follow crop rotation. Farmers perceptions about poor efficacy of herbicide were mainly poor quality of herbicide and herbicide resistance. Overall farmers assign first rank to 2,4-D with 1.36 rating and after 2,4-D, metribuzin was the second choice of farmers and assign 1.45 rating. Farmers have assigned 3rd position to clodinafop+ metribuzin with 2.07 rating. Metsulfuron-methyl was reported for not showing any control, so it was placed at last position by farmers with overall 2.96 rating. The numbers of farmers going for second spray was increased from 15.9% in 2016-17 to 55.6% in 2018-19 similarly numbers of farmers going for herbicide > 1 to 2 X dose of herbicide has been increased from 5.6% in 2016-17 to 53.0% in 2018-19. It may be concluded that there is problem with control of R. dentatus particularly by use of metsulfuron-methyl in Haryana. From pot bioassay study, it can be concluded that three biotype of R. dentatus viz.Ujha, Bhagwanpur and Gudha have been found resistance to metsulfuron-methyl at graded doses. None of the biotype was found resistance of carfentrazone-ethyl and 2,4-D. The findings of the study established that problem of resistance in R. dentatus in Haryana. From the field experiment, it can be concluded that pendimethalin (1000 g ha-1), 2,4-D ester (600 g ha-1), 2,4-D Na (1000 g ha-1), carfentrazone+ metsulfuron (25 g ha-1) were found at par to weed free treatment and also found as best treatments for controlling resistance population of R. dentatus and beside these carfentrazone-ethyl (20 g ha-1), 2,4-D amine (750 g ha-1) and metribuzin (210 g ha-1) were also found effective for controlling resistance population of R. dentatus. In nutshell, based on this study it may be concluded that resistance has started developing in R. dentatus against metsulfuron-methyl and 2,4-D, carfentrazone-ethyl, pendimethalin, carfentrazone+ metsulfuron and metribuzin could be used as alternate herbicide with proper spray techniques.
