(CCS HAU, Hisar, 2022-08) Zala Dashrathbhai Arajanbhai; Dadarwal, R.S
A field experiment entitled “Effect of integrated nutrient management (INM) on growth and yield of chickpea (Cicer arietinum L.) under irrigated condition” was conducted during Rabi 2021-22 at agronomy research area of CCS Haryana Agricultural University, Hisar. The experiment was done in randomized block design (RBD) with three replication and nine treatments. Treatments were T1: Control, T2: 100% RDF (18:48:0 kg t ha-1), T3: 100% vermicompost (3.00 t ha-1), T4: 75% RDF + 25% vermicompost (0.75 t ha-1), T5: 50% RDF + 50% vermicompost (1.5 t ha-1), T6: 25% RDF + 75% vermicompost (2.25 t ha-1), T7: 75% RDF + 25% vermicompost (0.75 t ha-1) + biofertilizers (Rhizobium + PSB), T8: 50% RDF + 50% vermicompost (1.5 t ha-1) + biofertilizers (Rhizobium + PSB) and T9: 25% RDF + 75% vermicompost (2.25 t ha-1) + biofertilizers (Rhizobium + PSB). Based on the experiment investigation, it was found that integrated nutrient management had significant effect on the growth parameters (plant height and dry matter accumulation), yield attributing characters (number of branches per plant, number of pods per plant and number of seeds per pod), yield (grain yield, straw yield and biological yield), NPK content in seed and straw, NPK uptake in grain and straw, NPK content in soil after harvest, net returns and benefit-cost ratio of chickpea. Among the different treatments maximum value of these parameters were recorded in the treatment with integration of 75% RDF + 25% vermicompost (0.75 t ha-1) + biofertilizers (Rhizobium + PSB) which in most of the cases was at par with 75% RDF + 25% vermicompost (0.75 t ha-1) and 100% RDF (18:48:0 kg t ha-1) but significantly higher to rest of the treatments and the minimum success was obtained in control. While the 100 seed weight and harvest index data were found to be non-significant. Treatment with 100% vermicompost has more K in soil after harvest. Also treatment with 100% RDF has more N and P in soil after harvest.

(CCS HAU, Hisar, 2022-08-16) Saroha, Siddharth; Vinod Kumar
A field experiment was conducted during Kharif 2021 to study the effect of bio-stimulant on growth and development of Bt Cotton at Cotton Research Area, CCS HAU Hisar, Haryana. The experiment was laidout in factorial randomized block design (FRBD) with three replications. The treatments comprised of two cotton varieties RCH 776 (Bt) and H 1098i (Non Bt) in treatment A with four sprays of bio-stimulants i.e., B1: Bio-stimulant at 30,45 and 60 DAS, B2: Bio stimulant at 45,60 and 75 DAS, B3: DMSO* spray 30,45,60 and 75 DAS and B4: Control water spray-30,45,60 and 75 DAS in treatment B. Cotton variety RCH 776 recorded significantly higher plant height as compared to H 1098i while plant height at harvest was not influenced due to spray of bio-stimulant and DMSO. The number of monopodia, no of sympodia and days to 50% boll brusting were statistically at par with each other in both of the genotypes and with spray of bio-stimulant. Boll weight in RCH 776 was higher as compared to H 1098i whereas boll weight was not significantly affected by spray of bio-stimulant. Significantly higher seed cotton yield was recorded with spray of Bio-stimulant B2 (Bio-stimulant at 45, 60 and 75 DAS) and B1 (Bio-stimulant at 30, 45 and 60 DAS) as compared to rest of the treatments.

Understanding rice-wheat system performance under pressurized irrigation and conservation agriculture practices
(CCSHAU Hisar, 2022-05-31) Jatana, Mansukh Singh; Parveen Kumar
Intensive tillage and open-field residue burning are tremendously propagated in conventional rice–wheat system (RWS) in recent past without much considering the economic profitability, soil health and environmental protection. This study aims at identifying a set of affordable crop management practices to suitably enhance the crop production and farm profitability in RWS with optimal resource use (tillage and residue management) and lower water footprints (higher water use efficacy) in ecologically sustainable manner. The present field experiment “Understanding rice-wheat system performance under pressurized irrigation and conservation agriculture practices” was carried out at the Research Farm of ICAR-Central Soil Salinity Research Institute (CSSRI), Karnal for two years (2019-20 and 2020-21) in rice-wheat rotation involving different tillage [puddled-transplanted rice (PTR), direct-seeded rice (DSR) in rice; conventional (CTW) and zero-till wheat (ZTW) in wheat], irrigation [surface (SIS), drip (DRIP) and sprinkler (MSIS)] and residue management [with (+RM) and without residue mulching (–RM)] options. A total of 4 treatments in rice and 7 treatments in wheat were laid out in a completely randomized block design with four replications. The results revealed that better soil moisture availability throughout the crop growing season in PTR led to improved morphological and physiological traits, ultimately culminating in enhanced yield components [filled grains panicle-1 (17%) and 1000-grain weight (8%)], yield (11%) and quality parameters in comparison to DSR. Notably, the yield penalty (10%) realized under DSR was subsequently compensated by better crop performance (14%) of ZTW. Positive changes in hydro-thermal regimes and better utilization of growth resources in pressurized irrigated residue mulched ZTW (DRIP/MSIS-ZTW+RM) ascertained improved leaf water status (RWC; 5% and 8%), water potential (12% and 7%), chlorophyll fluorescence (Fv/Fm; 6% and 10%), transpiration rate (E; 14% and 12%), photosynthetic rate (Pn: 7% and 13%), stomatal conductance (gS: 4% and 10%) at vegetative and reproductive stages, respectively resulting in enhanced crop growth and improved yield parameters; thereby attaining 17% higher wheat yields, 53% higher IWUE and 26% higher TWP with better grain quality [(protein; 1.6%) and grain hardiness (2.6%)], in comparison to CTW. Compared to conventional PTR/CTW system (11.61 t ha-1, 653 kg ha-cm-1, 2.81 kg m-3, respectively), adequate soil moisture availability and improved micro-climatic conditions in DRIP-DSR/ZTW+RM led to transformative alterations in morphological and physiological parameters of crop growth resulting in 11.86 t ha-1 grain yields, 1904 kg ha-cm-1 IWUE, and 3.62 kg m-3 TWP in system perspective. Switching from conventional RWS to drip-irrigated DSR/ZTW system receiving rice residue mulching in wheat (DRIP-DSR/ZTW+RM) could be a potential alternative in realizing the reduced tillage operations, rational crop water use and tackling residue burning problem while sustainably conserving the natural resources, improving soil health and rice-wheat performance in western IGPs and similar ecologies elsewhere.

(CCSHAU Hisar, 2022-08) Phogat, Pardeep; Amarjeet
The present investigation entitled “Response of green gram (Vigna radiata L.) to various agrochemicals for moisture stress mitigation under rainfed conditions” was carried out at Regional Research Station, Bawal, Rewari of CCS Haryana Agricultural University, Hisar (Haryana) during Kharif 2021. The objectives of the investigation were to study the effect of different agrochemicals on growth and yield; and to work out water use efficiency of mungbean under different treatments. The experiment was carried out in randomized block design (RBD)consisting of ten treatments of agrochemicals and with three replications. The treatments were control (T1), soil application of gondkatira @ 2.5 kg ha-1 (T2), soil application of gond-katira @ 5.0 kg ha-1 (T3), foliar spray of salicylic acid (SA) @ 100 ppm at flowering and pod initiation (T4), foliar spray of SA @ 200 ppm at flowering and pod initiation (T5), soil application of gond-katira @ 2.5 kg ha-1 + foliar spray of SA @ 200 ppm at flowering and pod initiation (T6), soil application of gond-katira @ 5.0 kg ha-1 + foliar spray of SA @ 200 ppm at flowering and pod initiation (T7), foliar spray of KNO3 @ 1 % at flowering and pod initiation (T8), soil application of gond-katira @ 2.5 kg ha-1 + foliar spray of KNO3 @ 1 % at flowering and pod initiation (T9) and; soil application of gond-katira @ 5.0 kg ha-1 + foliar spray of KNO3 @ 1 % at flowering and pod initiation (T10). Overall, the results of the one year experimentrevealed that among different agrochemical treatments, foliar spray of KNO3 @ 1 % alone (T8) or in combination with gond-katira @ 2.5 (T9) and 5.0 kg ha-1(T10) significantly improved growth, physiological, phenological and quality parameters; yield attributes, yield, economics; and water use of crop over control. Among different treatments, T10 (soil application of gond-katira @ 5.0 kg ha-1 + foliar spray of KNO3 @ 1 % at flowering and pod initiation) was found most productive and economicalwith 26.1 and 69.4% more seed yield and net returns over control, respectively. Highest water use efficiency of 3.3 kg ha-1 mm-1 was achieved with combination of gond-katira @ 5.0 kg ha-1 and foliar spray of KNO3 @ 1 % at flowering and pod initiation.

(CCS HAU, Hisar, 2022-08-23) Sumit; Kathwal, Rajesh
An investigation entitled “Growth and yield studies in newly developed wheat varieties under the influence of fertilizers and growth regulators” was conducted during Rabi 2021-22 at Research Farm, Department of Agronomy, CCS Haryana Agricultural University, Hisar. The field experiment was carried out in Split split plot design with eighteen treatment combinations viz., two varieties levels in the main plot, three fertilizer levels in the subplots (F1:100, F2:125 and F3:150 per cent RDF of NPK) and three growth regulator levels in sub sub plots (GR1 : Lihocin at 0.2% + 0.1% Folicur at 55 DAS (jointing stage) and 80-85 DAS (Flag leaf), GR2 : Lihocin at 0.4% + 0.1% Folicur at 55 DAS (jointing stage) and 80-85 DAS (Flag leaf) and GR3 : Control (no spray) replicated thrice. The results revealed that plant height at 60, 90 and 120 DAS was significantly reduced by both the growth regulators i.e., GR1 and GR2. Dry matter and tillers per metre row length was significantly influenced by growth regulator GR1. Fertilizer level F3 improved the tillers per metre row length at 30, 60, 90 and 120 DAS whereas in plant height at 60, 90 and 120 DAS. At growth regulator GR1, days to first node (51.7), days to jointing (71.8), days to heading (83.7), days to flowering (96.8), days to milking (110.6 days ) and days to maturity (135 days) came earlier as compared to GR3 (57.5, 76.6, 89.7, 103.8, 116.1 and 140.3 days). Maximum grain yield (5,585 kg ha-1), biological yield (19,127 kg ha-1) and straw yield (13,541 kg ha-1) was recorded at GR2. Maximum BC ratio (2.35 and 2.42) was estimated under fertilizer level F3 and growth regulator GR2. Based on the results achieved in the study, it can be inferred that both the newly developed wheat varieties of wheat i.e., DBW 303 and WH 1270 are at par in terms of yield (5,349 kg ha-1 and 5,454 kg ha-1)

(Chaudhary Charan Singh Haryana Agricultural University hisar, 2022-12) Nasir Ahmad Qazizadah; Bhagat Singh
A field experiment entitled “Effect of different establishment and moisture conservation practices on wheat under limited irrigated conditions” was carried out at research farm of Wheat and Barley Section, Department of Genetics & Plant Breeding, Chaudhary Charan Singh Haryana Agricultural University, Hisar, Haryana during the rabi seasons of 2019-20 and 2020-21. The experiment consisted of twenty four treatment combinations comprising, three establishment methods i.e., conventional tillage (CT), zero tillage (ZT) and bed planting (BP) and two irrigation levels i.e., I1-one irrigation applied at CRI stage (I1) and I2-two irrigations applied at CRI and booting stages as main plot treatments and four moisture conservation practices i.e., M0-no mulch, M1-mulch (pearl millet straw @ 4 tonnes ha-1), M2- antitranspirant (kaolin @ 6 % w/v) and M3- mulch (pearl millet straw @ 4 tonnes ha-1) + antitranspirant (kaolin @ 6 % w/v) as sub-plots treatment, were tested in split-split plot design with three replications. The maximum plant height was recorded under BP at 60, 90, 120 DAS and at harvest, which was significantly higher than CT and ZT during both the years. Whereas, significantly higher dry matter accumulation (g m-2) and number of tillers m-2 were recorded in CT as compared to ZT and BP during both the years of study. Plant height, number of tiller m-2 and dry matter accumulation were not influenced significantly by different irrigation levels upto 90 DAS. However, at 120 DAS and harvesting stage plant height, number of tillers and dry matter accumulation were recorded significantly higher when two irrigations were applied to the crop at CRI and booting stage (I2) as compared to one irrigation applied at CRI stage (I1) during both the years of study. Among moisture conservation practices, plant height, number of tillers and dry matter accumulation were significantly higher in the treatment M3 as compared to M0 being at par with M1 and M2 during both the years of study. Crop phenology i.e., days taken to the emergence, booting, heading and to attain the physiological maturity stages did not influence by different crop establishment methods during both the years of study. Among the irrigation levels, crop took significantly more number of days to attain booting, heading and physiological maturity stages when two irrigations were applied to the crop as compared to one irrigation (I1) during both the years of study. Among the moisture conservation treatments, treatments M3 and M1 took significantly more days to attain all the phenology stages as compared to M2 and M0 during both the years of study. Yield attributes, i.e., spike length, spikelet’s spike-1 (cm), number of grains spike-1 and test weight (g) and grain yield were significantly higher under BP method of sowing as compared to CT and ZT during both the years of study. Application of two irrigation (I2) produced significantly more spike length, spikelet’s spike-1, number of grains spike-1, test weight and number of effective tillers m-2 as compared to one irrigation (I1) during both the years of study. Among moisture conservation practices, treatment M3 recorded significantly higher spike length, spikelet’s spike-1, number of grain spike-1, test weight and number of effective tillers m-2 over M0 being statistically at par with M1 and M2 during both the years of study. Whereas, number of effective tillers m-2, biological and straw yield were recorded significantly higher under CT as compared to ZT and BP during both the years. Among irrigation levels, significant higher biological, grain and straw yields were recorded under I2 treatment as compared to I1 during both the years of study. Among moisture conservation treatments, significantly higher biological, grain and straw yields were recorded under the treatment M3 over M0 being statistically at par with M1 and M2 during both the years of study. However, harvest index and attraction index (%) of wheat did not differ significantly among different crop establishment treatments, irrigation levels and moisture conservation treatments. Growth indices i.e., crop growth rate (g/m2/day), relative growth rate (g/g/day), leaf area index (LAI) and leaf area duration (Days) were significant higher under BP method of sowing as compared to CT and BP during both the years of study. Maximum CGR, RGR, LAI and LAD were recorded when two irrigations were applied to the crop, which was significantly higher over one irrigation during both the years of study. At 61-90, at 91-120 and 121 DAS to harvesting stage, treatment M3 recorded significantly higher CGR, RGR and LAI over all other treatments i.e., M0, M2 and M1. At anthesis and 15 days after anthesis, significantly lower canopy temperature was recorded in bed planting over ZT but statistically at par with CT. At anthesis and at 15 days after anthesis, significantly higher canopy temperature was recorded in I1 over I2. Among moisture conservation practices, significantly higher canopy temperature was noticed in M0 over M2, M1 and M3 at anthesis and at 15 days after anthesis. At anthesis stage, significantly higher WUE, RWC, chlorophyll stability index, chlorophyll a, chlorophyll b and total chlorophyll (a+b) were recorded in BP method of sowing as compared to CT and ZT. At anthesis stage, significantly higher RWC, chlorophyll stability index, chlorophyll a, chlorophyll b and chlorophyll (a+b) was recorded under treatment I2 as compared to I1. Among moisture conservation practices, significantly higher RWC, chlorophyll stability index, chlorophyll a, chlorophyll b and total chlorophyll (a+b) were recorded in treatment M3 over M0, M2 and M1 during both the years. Among the crop establishment, maximum consumptive use of water was recorded in CT followed by ZT and the minimum was recorded in BP. Among irrigation schedules, the maximum consumptive use of water was recorded in I2 and minimum was noticed in I1 treatment. Among the moisture conservation practices, the maximum consumptive use of water was recorded in M0 treatment followed by M2 and M1 and the lowest consumptive use of water was recorded in M3. Maximum WUE was recorded in the I1 treatment whereas, minimum WUE was noticed in the I2 treatment. Among moisture conservation practices, the maximum water use efficiency was recorded in the treatment M3 followed by M1 and M2 and the minimum was recorded in M0 during both the years. Maximum cost of cultivation was recorded in CT followed by BP and ZT during both the years. However, maximum gross returns were recorded in BP followed by CT and ZT during both the years. Maximum cost of cultivation and gross returns were recorded in I2 treatment followed by I1 treatment. Among moisture conservation practices, maximum cost of cultivation and gross returns was recorded in treatment M3 followed by M1, M2 and M0 during both the years. Among the crop establishment methods, wheat sowing by zero tillage brought out the maximum net returns (₹28056 and ₹15879 ha-1) and B:C ratio (1.34 and 1.18) as compared to CT and BP during 2019-20 and 2020-21, respectively. Maximum net returns (₹28340 and ₹17410 ha-1) and B:C ratio (1.32 and 1.18) were recorded in the treatment I2 (two irrigation) and minimum net returns were recorded by I1 during 2019-20 and 2020-21, respectively. Among the moisture conservation practices, maximum net returns (₹31465 and ₹19515 ha-1) and B:C ratio (1.38 and 1.22) were recorded in M2 treatment followed by M0, M3 and M1 during 2019-20 and 2020-21, respectively.

(Chaudhary Charan Singh Haryana Agricultural University hisar, 2022-12) Akshay Kumar; Satyajeet
The field experiment was conducted during Rabi season of 2021-22 at Research Farm of Chaudhary Charan Singh Haryana Agricultural University, Regional Research Station, Bawal, Rewari (Haryana) to find out the effect of different date of sowing and integrated nutrient management on growth, yield attributes and yield of wheat crop and to compute economics of different treatments. The experiment was laid out in split plot design with four dates of sowing (31st October, 7th, 14th and 21st November) in main plots and four nutrient management levels (Control, 100% RDF, 75% RDF + 25% N (FYM) and 75% RDF + 25% N (FYM) + Azotobacter + PSB) in sub-plots with three replications. Among date of sowing significantly higher growth parameters were recorded under 31st October sown crop as compared to 21st November, which were statistically at par with 7th November sown crop at various growth stages. Crop sown on 31st October took significantly higher number of days to attain 50% flowering and physiological maturity as compared to 21st November. Sowing of wheat on 31st October resulted in significantly higher yield attributes and total N, P and K uptake by crop as compared to 21st November sown crop. Significantly higher grain yield (5017 kg/ha) and straw yield (7361 kg/ha) were recorded under crop sown on 31st October as compared to 21st November, which were statistically at par with 7th and 14th November sown crop. Highest net returns (INR 52071/ha) and B:C (1.63) were obtained from 31st October sown crop followed by 7th, 14th and 21st November. Under integrated nutrient management significantly higher growth parameters were recorded under 100% RDF as compared to control at various growth stages. Significantly higher yield attributes, protein content, total N, P and K uptake by crop were recorded under 100% RDF as compared to control, which were statistically at par with 75% RDF + 25% N (FYM) + Azotobacter + PSB. After harvest of crop available N in soil was significantly higher under 75% RDF + 25% N (FYM) + Azotobacter + PSB as compared to control. After harvest of crop available K in soil was significantly higher under 75% RDF + 25% N (FYM) as compared to control. 100% RDF recorded significantly higher grain yield (5144 kg/ha) and straw yield (7647 kg/ha) as compared to control, which were statistically at par with both the INM treatments (75% RDF + 25% N (FYM) and 75% RDF + 25% N (FYM) + Azotobacter + PSB). Highest net returns (INR 57673/ha) and B:C (1.72) were obtained from 100% RDF followed 75% RDF + 25% N (FYM) + Azotobacter + PSB, 75% RDF + 25% N (FYM) and control.

Effect of foliar application of nano-nitrogen on growth and yield of wheat grown under long term FYM amended soil
(Chaudhary Charan Singh Haryana Agricultural University hisar, 2022-09) Nanda, Akshaya Kumar; Garg, Rajbir
A field experiment entitled “Effect of foliar application of nano-nitrogen on growth and yield of wheat grown under long term FYM amended soil” was conducted during rabi season of 2021-22 at Soil Science Research Farm of CCS Haryana Agricultural University, Hisar. The experiment consisted of a combination of four levels of FYM treatments (0, 5, 10 and 15 t/ha) in main plot, three levels of nitrogen (0, 60 and 120 kg/ha) and two nano- nitrogen treatments (with and without application of nano-nitrogen) in sub-sub plot laid out in split-split-plot design with three replications. The results in general indicated that highest values of crop growth parameters like plant height, dry matter accumulation, LAI and number of tillers/m2 were recorded with the application of FYM 15 t/ha. The yield attributing characters, wheat yield (grain yield, straw yield and biological yield), nutrient (NPK) uptake by crop were also significantly higher where FYM 15 t/ha was applied in comparison to lower doses. The positive response was observed even at lower doses of FYM in comparison to control. Similarly, application of 120 kg N/ha significantly increased growth parameter, yield and yield attributes as compared to 60 kg N/ha and control treatment. The application of nanonitrogen was also found effective in achieving significantly higher growth, yield attributes and yield than treatment where nano-nitrogen was not applied. The nano-nitrogen also significantly increased the nitrogen content in grain and straw and NPK uptake by the crop. The combined application of FYM 15 t/ha along with 120 kg N/ha and two spray of nano-nitrogen proved the best integrated package recording the highest grain, straw and biological yield of wheat. Gross returns, net returns and benefitcost ratio were also maximum under combined application of 15 t/ha farm yard manure, 120 kg N/ha and nano nitrogen. This study proved that INM practice is the viable and feasible option for increasing the wheat productivity and nano-nitrogen would also be key component of INM practices in the coming years.

(Chaudhary Charan Singh Haryana Agricultural University hisar, 2022-12) Diwedi, Aniket; Thakral, S. K
A field experiment was carried out during winter 2017-18 and 2018-19 at RRS, Kaul, Haryana. The experiment comprising of 4 level of varieties in main plots (WH 1080, WH 1025, WH 1142 and WH 711) and 5 levels of nutrient combination in subplots (Control, 100% RDF, 50% RDF + 50% RDF through FYM, 50% RDF + 50% RDF through vermicompost and 50% RDF + 50% RDF through FYM + 50% RDF through vermicompost + biofertilizers (seed treatment) was carried out in split plot design with three replications. The soil of the experimental plot was clay loam in texture and slightly alkaline in reaction with pH 7.9 and EC of 0.27 dS/m. The soil was low in available nitrogen (107.8 kg/ha), high in available phosphorus (25.4 kg/ha), high in available potassium (313.2 kg/ha), copper (1.37 mg/kg), iron (13.45 mg/kg), manganese (2.85 mg/kg) and zinc (1.76 mg/kg) before sowing. The objective of experiment was effect of varieties and nutrient sources on growth attributes, yields and yield attributes, quality, nutrient content by wheat, nutrient uptake by wheat, available OC, N, P, K, Fe, Mn, Zn and Cu in soil at harvest, nitrogen removal ratio, nitrogen use efficiency and most profitable nutrient sources and varieties. Significantly higher mean plant population, plant height, LAI, LAD, dry matter accumulation and shoot length were recorded in variety WH 1142 and 100% RDF, respectively. Days taken to 50% heading and 50% anthesis was shorter in variety WH 1025 and in control treatment among nutrient sources. Yield attributes viz. mean number of effective tillers/m2, spike length (cm), number of grains/spike, grains weight/spike (g) and 1000-grain weight were significantly higher in wheat variety WH 1142 and in nutrient sources with 100% RDF. Mean protein and starch content in grain is significantly influenced by application of 100% RDF. WH 1142 gives significantly higher mean grain yield of 4866 kg/ha and 4877 kg/ha, respectively during 2017-18 and 2018-19 over other varieties (WH 1080, WH 1025 and WH 711). Significantly higher mean grain (4736 and 4758 kg/ha) and straw yield (7652 and 7719 kg/ha) were recorded in 100% RDF during 2017-18 and 2018-19, respectively over other nutrient sources. Application of 50% RDF + 50% RDF through FYM + 50% RDF through vermicompost + biofertilizers (seed treatment) resulted in significantly higher grain and straw yield over other integrated approach. Among interaction effect significantly higher grain and straw yield were recorded in WH 1142 × 100% RDF during 2017-18 and 2018-19. Mean N, P and K content and uptake by grain and straw was significantly higher in variety WH 1142, which is followed by variety WH 711, WH 1080 and WH 1025 during 2017-18 and 2018-19. Available mean N, P and K content in soil at harvest were incresaed in plot receiving 100% RDF as compared to initial status. However significant increase in available mean organic carbon and DTPA-extractable Fe, Mn, Zn and Cu in soil at harvest recorded in treatment receiving 50% RDF + 50% RDF through FYM + 50% RDF through vermicompost + biofertilizers (seed treatment) over initial status of soil. Use efficiency (AE, PE and RE) of nitrogen was significantly higher in 100% RDF, due to higher uptake by crop and higher yields. Highest mean net return (53282 and 56828 Rs./ha) were incurred with variety WH 1142 and among nutrient sources with 100% RDF (51227 and 54019 Rs./ha) during 2017-18 and 2018-19. The higher BCR of wheat was recorded in variety WH 1142 (1.60 and 1.64) over all other varieties and among nutrient sources in 100% RDF (1.59 and 1.61) during 2017-18 and 2018-19.
