    Effect of sewage water and sewage sludge on fodder sorghum
    (CCSHAU, 2009) Mahesh Kumar; Pahuja, S.S.
    A field experiment entitled, “Effect of sewage water and sewage sludge on sorghum (Sorghum bicolor L.)”, was conducted during kharif season at the KVK Sonipat of CCS Haryana Agricultural University, Hisar (India). The soil of the experimental field was sandy loam in texture; low in organic carbon, nitrogen; low in phosphorus; high in potassium and slightly alkaline in reaction. The field experiment was laid out in split plot design with three replications. The treatments consisted of all irrigation with sewage water (4 irrigation), 3 irrigation with sewage water + 1 irrigation with tube well water, 2 irrigation with sewage water + 2 irrigation with tube well water, 1 irrigation with sewage water + 3 irrigation with tube well water and all irrigation with tube well water in main plot treatments and sewage sludge @ 10 t ha-1, 50% sewage sludge + 50% recommended fertilizers and recommended fertilizer (80 kg N + 30 kg P2O5) in subplots. The irrigation treatments where all irrigation with sewage water proved its superiority over irrigation treatments with tube well water in respect of plant height, dry matter accumulation. The nitrogen, phosphorus, potassium content and uptake was superior where all irrigation with sewage water were applied Significantly the crop harvested higher fodder yield where all irrigation were applied with sewage water. The pH of the soil decrease with the use of sewage water. EC, organic carbon and micronutrient content of soil increased where all irrigation were applied with sewage water compared to where all irrigation were applied with tube well water. Growth parameters, viz., plant height, dry matter accumulation and fodder yield of crop increased with the use of sewage sludge @ 10 t ha-1 over control where recommended fertilizer were applied. The total N, P, K content and uptake, protein content were significantly higher where we use sewage sludge @ 10 t ha-1 were applied compared to recommended fertilizer Based on the study it may be concluded that the application of sewage water and sewage sludge harvested maximum plant height, dry matter accumulation, and fodder yield. The protein content, organic carbon, N, P, and K increased significantly with the use of sewage water and sewage sludge.

    Response of basmati rice varieties to time of transplanting
    (CCSHAU, 2009) Mukesh; Ishwar Singh
    The present study entitled “Response of basmati rice varieties to time of transplanting” was carried out at Research Farm of CCS Haryana Agricultural University Rice Research Station, Kaul (Kaithal) during kharif season of 2008-09 on clay loam alkaline soil, low in organic carbon and available nitrogen, medium in phosphorus and high in potassium. The treatments consisted of three dates of transplanting (June 25, July 10 and July 25) and four varieties (Taraori Basmati, CSR-30, Pusa Basmati-1 and Pusa Sugandha-4) laid out in split-plot design with four replications, keeping transplanting dates in main plots and varieties in sub plots. Thirty days old seedlings of the crop were transplanted mainly on a well puddled soil at a hill spacing of 20 x 15 cm with two seedlings per hill. The studies revealed that, the early transplanting (June 25 and July 10) significantly increased all the crop growth parameters viz. plant height, tillers/m2, dry matter accumulation and leaf area index over the late transplanting (July 25). The yield contributing characters (panicles/m2, grains/panicle), yield (grain and straw), net profit and benefit cost ratio were higher with early transplanting dates as compared to late planting. The late planting, however, improved the quality traits viz. hulling, milling and head rice recovery than early planting. Among the varieties, tall varieties (Taraori Basmati and CSR-30) took longer time to attain 50% flowering and maturity than semi dwarf varieties. The semi dwarf varieties produced more tillers/m2 than taller ones but reverse was true for dry matter accumulation, leaf area index, hulling, milling and head rice recovery. Pusa Sugandha-4 was found best as it gave the highest grain yield, net income, benefit cost ratio, longest kernel and length breadth ratio than all other varieties.

    (CCSHAU, 2009) Asha Ram; Pannu, R.K.
    The field experiment entitled, “Agronomical management of late sown wheat” was conducted at Agronomy Research Farm of CCS Haryana Agricultural University, Hisar, during rabi season of 2007-08. The experiment was laid out in randomized block design. There were ten treatment combinations namely :(T1 )-dry seeding on15th December followed by irrigation, (T2)-dry seeding with overnight soaked seed on15th December followed by irrigation, (T3)-dry seeding with 25% higher seed rate on15th December followed by irrigation, (T4)-dry seeding with overnight soaked seed with 25% higher seed rate on15th December followed by irrigation, (T5)-dry seeding on 1st January followed by irrigation, (T6)-dry seeding with overnight soaked seed on 1st January followed by irrigation, (T7)-dry seeding with 25% higher seed rate on 1st January followed by irrigation, (T8)-dry seeding with overnight soaked seed with 25% higher seed rate on 1st January followed by irrigation, (T9)-dry seed sowing on 1st January after pre sowing irrigation on 15th December and (T10)-soaked seed sowing on 1st January after pre sowing irrigation on 15th December. The treatment T4 observed with highest number of seedling emergence and minimum number of seedling was found in T5. The days taken to attainment of heading, anthesis and physiological maturity were recorded significantly higher in 15th December sown treatments as compared to 1st January sown treatments. The dry matter accumulation, LAI, LAD and CGR were recorded significantly higher in T4 than all other treatments. Among the yield attributing characters number of effective tillers/mrl was found highest in T4 followed by T3 and minimum in T5. But, among all the treatments T4 observed with significantly higher grain yield (4196 kg/ha) and biological yield (10359 kg/ha). Significantly lower grain (2885 kg/ha) and biological yield (7426 kg/ha) were observed in T5 as compared to all other treatments except T6 with which it was found statistically at par. The LAI, LAD, CGR, RGR and NAR have shown highly significant and positive correlation among themselves and with grain yield. Among the yield attributes number of effective tiller/mrl had significant association (r = 0.97) with grain yield, biomass yield and straw yield of wheat also had significant positive association (r = 0.99).

    (CCSHAU, 2009) Vandana; Pahuja, S.S.
    The present study entitled “Response of pearl millet hybrid (HHB-197) to different organic and inorganic sources of nutrients” was conducted at Research Farm, Chaudhary Charan Sing Haryana Agriculture University, during the kharif season of 2008 with the objectives to study the effect of organic and inorganic sources of nutrients on growth and yield of pearl millet hybrid HHB-197and to work out the NPK content and uptake both in grain and stover and economics of pearl millet cultivation under different treatments. Twelve different treatments viz. Control (no fertilizer), 75 % RDF + FYM @ 5t ha-1, 100 % RDF + FYM @ 5t ha-1 , 75 % RDF + FYM @ 10 t ha-1, 100 % RDF + FYM @ 10 t ha-1 , 75 % RDF + Vermicompost @ 2.5 t ha-1 , 100% RDF + Vermicompost @ 2.5 t ha-1, 75 % RDF + Vermicompost @ 5 t ha-1, 100% RDF + Vermicompost @ 5 t ha-1 , 75 % RDF, 100% RDF, 125 % RDF were tested in randomized block design with three replications. Though different nutrient management practices did not differ significantly in respect to various phenological events viz. emergence, five leaf stage, panicle initiation stage, flag leaf stage, 50 per cent flowering, milk stage, dough stage and physiological maturity and plant population per hectare. Growth parameters i.e. plant height (cm), total number of tillers plant-1, dry matter accumulation (g/plant), leaf area per plant (cm2) and yield attributing characters [number of earheads/plant, earhead length (cm), earhead girth (cm) and test weight (g)] and grain, stover yield (kg/ha) differed significantly among various treatments. Among all the treatments T12 recorded significantly higher N, P and K content and their uptake in grain as well as in stover. The highest gross returns (Rs. 46518 ha-1), net returns (Rs. 25568 ha-1) and B:C ratio (2.22) were found in treatment T12 (125% RDF- 150 kg N + 75 kg P2O5 ha-1) followed by T9 (100% RDF- 120 kg N + 60 P2O5 ha-1 + Vermicompost @ 5t ha-1). The grain yield in T12 and T9 treatments were 82% and 77.9% higher over control respectively, whereas the stover yield of T12 and T9 treatments were 56.1% and 54.3% higher than control.

    (CCSHAU, 2009) Prasad, Dasharath; Bangarwa, A.S.
    The field experiment entitled, “Effect of different plant population on chickpea genotypes under late sown conditions”was conducted at Agronomy Research Farm of CCS Haryana Agricultural University, Hisar, during rabi season of 2007-08. The main treatments consisted of three dates of sowing viz. December 1st, December 10th and December 20th; three genotypes HC-1, PBG-1 and BG-372.two plant population 30x10 and 30x7.5 cm were kept in subplots. Eighteen combinations were tested in split plot design with three replications. Significantly better grain yield was recorded with December 1st as compared to other sowing dates. The grain yield was significantly affected due to the genotypes of chickpea. Genotypes HC-1 produced significantly higher grain yield followed by BG-372 and PBG-1. Significant decline in growth and yield attributing character was recorded when sowing was delayed from December 1st to December 20th sowing. Total N P and K uptake was recorded higher with December 1st. Total N P and K uptake was also more with genotype HC-1. The plant population of 30x7.5 cm more grain yield compared to other. The crude protein content of chickpea was not affected significantly due to the sowing dates, genotypes and plant population.

    (CCSHAU, 2009) Neelam; Singh, V.P.
    The present study entitled, “Compensating N and P requirement through biofertilizers in Pearl millet under rainfed situation” was conducted during the kharif season of 2008 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, microbial biomass at 30 DAS and after harvest and economics of pearl millet hybrid HHB-197 under different treatments. Ten different treatments were taken for the experimental study: (T1) Control (T2) Azotobacter (T3) Biomix (Azotobacter+Azospirillum+Phosphate solubilizing bacteria) (T4)20 kg N ha-1+10 kg P2O5 ha-1+Azotobacter (T5)30 kg N ha-1+20 P2O5 kg ha- 1+Azotobacter (T6)40 kg N ha-1+30 kg P2O5 ha-1+ Azotobacter (T7)20 kg N ha-1+10 kg P2O5 ha-1 +Biomix (T8)30 kg N ha-1+ 20 kg P2O5 ha-1+Biomix (T9)40 kg N ha-1+30 kg P2O5 ha-1 +Biomix (T10)60 kg N ha-1+40 kg P2O5 ha-1. Different nutrient management practices did not differ significantly in respect of various phenological events viz. emergence, five-leaf stage, panicle initiation stage, flag leaf stage, 50 percent flowering, milk stage, dough stage and physiological maturity and plant population. The growth parameters viz. [plant height (cm), LAI, total number of tillers/plant, dry matter accumulation/plant (g/plant) and leaf area/plant (cm2)], yield attributing characters [number of earheads/plant, earhead length (cm), earhead girth (cm), test weight (g)] and grain, stover yield (kg/ha) differed significantly among 19 different treatments. Among all the treatments T10 recorded significantly higher N and P content and their uptake as well as in protein content in grain and stover. The treatments involving biofertilizers along with inorganic fertilizer improved the microbial population (Azotobacter+Azospirillum+Phosphate solubilizing bacteria) as compared to inorganic fertilizers alone. The population of different microbial groups was more at 30 DAS compared to that at harvest. Azotobacter, Azospirillum and Phosphate solubilizing bacteria varied from 103 to 104, 104 to 105 and 105 to 106 respectively after harvest and 30 DAS. The highest gross returns (Rs. 43415 ha-1), net returns (Rs. 23884 ha-1) and B:C ratio (2.22) were found in the treatment T10 (60 kg N ha-1+40 kg P2O5 ha-1) followed by T9 (40 kg N ha-1+30 kg P2O5 ha-1+Biomix). Grain yield of T10, T9 and T6 treatments were higher by 105.1%, 96.5% and 88.6% respectively than the control and the stover yield of T10 and T9 treatments was 78.2% and 68% higher than the control. Hence the biomix inoculation can save 20 kg N ha-1 +10 kg P2O5 ha-1.

    Effect of spacing and fertilizer on growth, yield and quality of Bt cotton (Gossypium hirsutum L.) genotypes
    (CCSHAU, 2009) Mandeep Kumar; Pannu, R.K.
    A study entitled, “Effect of spacing and fertilizer on growth, yield, and quality of Bt cotton (Gossypium hirsutum L.) genotypes”, was conducted at Research Farm, Department of Agronomy, CCS, Haryana Agricultural University, Hisar during Kharif 2006. The soil of experimental field was sandy loam in texture and slightly alkaline in pH. Soil tested low in organic carbon and available nitrogen and high in available phosphorus and potassium. The experimented was conducted in split plot design with three replications. The combination of three spacings (67.5 x 60 cm, 100 x 45 cm and 100 x 60 cm), three fertilize levels viz., F1 112.5: 45: 45 NPK Kg/ha), F2 xix 150.0: 50: 50 NPK Kg/ha), F3 187.5: 75: 75 NPK Kg/ha), were kept in main plots while three hybrids viz. JKCH 1050 Bt, JKCH 1945 Bt and HHH 223 non Bt were kept in subplots. Maximum plant height was recorded at wider spacing of 100x 45 cm followed plant spacing had a significant effect on dry matter accumulation. Maximum sympodial branches / plant were recorded in wider spacing (100 x 60 cm) which were significantly higher than closer spacing (100 x 45 cm and 67.5 x 60 cm). Seed cotton yield (Kg/ha) was highest in wider spacing (100 x 45 cm) that was higher than 67.5 x 60 cm and 100 x 60 cm respectively. Maximum oil content (%) and protein content (%) recorded in cotton seed in wider spacing (100 x 60 cm) which were significantly higher than closer spacings (100 x 45 cm and 67.5 x 60 cm). Plant spacing had a significant effect on N and K uptake but non-significant effect on phosphorus uptake by the crop. Total NPK uptake cotton seed was highest in S2 with a significant difference with S1.Nitrogen uptake by crop was non-significant. Total uptake of NPK by cotton crop under F1and F3 fertilizer doses did not differ significantly. Maximum potassium uptake was recorded in HHH 223 non-Bt than JKCH 1050 Bt followed by and JKCH 1945 Bt. The genotypes did not differ in N, P and K uptake by cotton seed as well as total uptake by crop. Spacing 67.5 x 60 cm and 100 x 45 cm resulted in higher total cost of cultivation, gross returns and net returns than 100 x 60 cm with 100% and 125% of recommended dose of fertilizers. Benefit : cost ratio was significantly better in spacing 67.5 x 60 cm and 100 x 45 cm with 75% and 100% of recommended dose of fertilizers.

    Weed management in transplanted rice
    (CCSHAU, 2009) Naresh Kumar; Nandal, D.P.
    The present investigation was carried out at the Students’ Farm of College of Agriculture, CCS Haryana Agricultural University, Kaul (Kaithal) during Kharif 2008. The main objective was to find out the best herbicide, which control the weeds significantly and help in crop growth. The experiment consisted of fifteen treatments viz., two doses of post-emergence herbicides, bispyribac sodium (25 and 30 g/ha) and azimsulfuron (30 and 40 g/ha) with two timings of their application (20 and 25 DAT) and one dose of fenoxaprop-p-ethyl 56.25 g/ha (25 DAT). Four pre-emergence herbicides pretilachlor 750 g/ha, butachlor 1500 g/ha, oxadiargyl 100 g/ha, pyrazosulfuron 20 g/ha along with weedy and weed free checks and were laid out in randomized block design with three replications. The experimental field was dominated by grassy, broad leaf weeds and sedges viz. Echinochloa colona, Echinochloa crusgalli, Ammania baccifera, Ludwigia parviflora, Lindernia spp., Marsilea quadrifolia, Cyperus iria and Cyperus difformis. The weed dry weight and density were significantly lowest in pretilachlor treatment. The growth parameter plant height, tillers/m2 and crop dry matter accumulation/m2 were statistically higher in pretilachlor treatment. Grain and straw yield was also significantly higher in pretilachlor treatment. Among the new post-emergence herbicides bispyribac sodium 25 & 30 g/ha (20 DAT) was found excellent herbicide. Bispyribac sodium 25 & 30 g/ha (20 DAT) were statistically at par to weed free treatment to control the grassy weeds and sedges. Azimsulfuron 30 & 40 g/ha (20 DAT) were statistically at par to weed free treatment in controlling broad leaf weeds. Butachlor 1500 g/ha and pyrazosulfuron 20 g/ha (3 DAT) were significantly at par to weed free treatment to control all types of weeds. Gain and straw yield of pretilachlor, butachlor, bispyribac sodium (25 and 30 g/ha applied at 20 DAT) and pyrazosulfuron were statistically at par to weed free treatment.
