    Performance of late sown Indian mustard (Brassica juncea L.) under varying fertilizer doses and crop geometry
    (2016) Rathi, Naveen; Bikram Singh
    An investigation entitled “Performance of late sown Indian mustard (Brassica juncea L.) under varying fertilizer doses and crop geometry” was conducted during rabi, 2015-16 in Clusterbean- Indian mustard cropping system at Regional Research Station, Bawal, Rewari of CCS Haryana Agricultural University. The treatments comprised of four fertilizer doses viz. 70% RDF (F1), 85 % RDF (F2), RDF (Recommended dose of fertilizer i.e. 80 kg N + 30 kg P2O5 + 20 kg K2O + 40 kg S/hectare) (F3) and 115 % RDF (F4) in main plot and sub plot consisted of six crop geometries viz.30 cm x 10 cm (P1 : 3.33 lakh plants/hectare), 25 cm x 15 cm (P2 : 2.66 lakh plants/ ha), 30 cm x 15 cm (P3 : 2.22 lakh plants/ha), 25 cm x 20 cm (P4 : 2.00 lakh plants/ha), 30 cm x 20 cm (P5 : 1.66 lakh plants/ha) and 25 cm x 25 cm (P6 : 1.00 lakh plants/ha). These were tested in split plot design with three replication. Among various fertilizer doses, application of 85% RDF in late sown Indian mustard recorded significantly higher growth parameter viz . plant height, leaf area index, number of primary branches and secondary branches/plant and dry matter accumulation (g/plant); yield attributes viz. number of siliquae/plant, number of seeds/siliqua, seed yield/plant and seed yield; protein content, nutrient content (NPKS) and their uptake in seed and stover over 70% RDF and further increase in fertilizer doses (100% and 115% RDF) did not bring significant increase over 85% RDF. Water use efficiency was also higher at 85% RDF. While reverse trend was observed with respect to oil content. F2 recorded highest net monetary returns and B:C ratio and was found most economical. Crop geometry of 25 cm x 15 cm (2.66 lakh plants/ha) had better seed yield, stover and biological yield and nutrient uptake (NPKS) over all other crop geometries under study. While other parameters were higher under wider spacing of 25 cm x 25 cm. Hence, plant spacing of 25 cm x 15 cm was found optimum and economical for late sown Indian mustard. Therefore, late sown Indian mustard taken after clusterbean should be sown at optimum plant spacing of 25 cm x 15 cm and should be fertilized with 85% RDF to achieve highest seed yield, net monetary returns and B:C ratio.

    (CCSHAU, 2016) Kavinder; Malik, Yash Pal Singh
    A field experiment entitled “Study on weed dynamics in wheat under long term FYM and fertilizer nitrogen application in soil” was conducted during rabi season of 2014-15 at Soil Science Research Farm of CCS Haryana Agricultural University, Hisar. The experiment consisting a combination of two level of FYM (0, 15 t/ha) and three mode of application (kharif, rabi and both kharif and rabi) in main plots whereas, two level of nitrogen (0 and 120 kg/ha) and two weed control treatment (weed free and weedy check) in sub plot was laid out in split-plot design with three replications. Based on the research investigation, it was observed that highest values of crop growth parameters like plant population, LAI and plant height were recorded under the application of FYM 15 t/ha in both the seasons which were significantly superior to FYM 0 t/ha (control) while statistically at par with FYM 15 t/ha applied either in rabi or in kharif. Crop dry matter accumulation, number of tillers/m 2 , yield attributing characters, wheat yield (grain yield, straw yield and biological yield), nutrient uptake by crop were significantly higher where FYM 15 t/ha was applied in both rabi and kharif season as compared to addition of FYM 15 t/ha either in rabi or kharif and control. Similarly, application of 120 kg N/ha significantly increased growth parameter, yield and yield attributes as compared to treatment where no nitrogen was applied. Application of FYM 15 t/ha along with 120 kg N/ha also significantly improved the growth and yield of wheat. The density of A. arvensis and M. Indica decreased with increasing fertility level having highest number of these weeds under control treatments, whereas, density of C. didymus, R. dentatus and miscellaneous weeds, total dry matter of weeds along with uptake and content of NPK in weeds increased with increasing fertility level having highest values of these with application of FYM 15 t/ha along with 120 kg N/ha. Gross returns, net returns and B: C were maximum under application of 15 t/ha in both rabi and kharif season along with 120 kg N/ha and weed free treatment. The combined application of FYM 15 t/ha in both rabi and kharif season along with 120 kg N/ha and weed free treatment gave significantly higher value of growth and yields of wheat and its economic returns.

    Effect of planting methods and residue management on weeds and productivity of maize (Zea mays L.) hybrids
    (CCSHAU, 2016) Rajbir Singh; Yadav, Dharam Bir
    A field experiment was conducted at Regional Research Station, Uchani, Karnal of CCS Haryana Agricultural University, Hisar, Haryana (India) during kharif 2015. Treatments comprised of four main plot treatments (planting methods) viz., raised bed with residue, raised bed without residue, zero tillage with residue and zero tillage without residue, and six sub-plot treatments with combination of three maize hybrids viz., HQPM-1, HM-4 and HM-10 and two weed control treatments viz., atrazine 750 g/ha (PRE) fb 1 HW at 30 DAS and unweeded check. The experiment was laid out in split plot design with three replications. Weather data revealed that rainfall received during the cropping season was 430.3 mm, which was well-distributed up to September which resulted in good crop stand and growth. Important weed species observed in the experimental plots were Dactyloctenium aegypticum, Brachiaria reptans, Eragrostis tenella, Portulaca oleracea, Ammania baccifera and Cyperus rotundus along with some other broadleaf weeds. In planting methods, zero tillage with residue recorded lowest density and dry weight of weeds, higher grain and stover yields and net income with good crop growth at all growth stages as compared to other methods. Zero-tillage (ZT) was found superior to raised bed due to lower weed density and dry weight, better growth parameters (plant height, LAI, CGR, dry matter accumulation), yield attributes (cob length, girth and weight, number of grains/cob, 100-grains weight, harvest index), net returns and B: C. ZT gave grain and stover yields at par with raised bed. Similarly, residue retention was better than without residue in respect of all the above parameters including yields and net returns. Lower weed density were recorded in HM-10 and HM-4 as compared to HQPM-1. The hybrid HM-4 provided minimum dry weight for broadleaf weeds, maximum yield attributes and yield fetching higher net returns and B: C, while HM-10 had minimum dry weight for grassy weeds and sedges with higher growth parameters. In weed control methods, lower density and dry weight of weeds, higher grain and stover yields, net income and B: C were obtained with application of atrazine 750 g/ha (PRE) fb 1 HW at 30 DAS, with good crop growth and growth indices at all growth stages as compared to unweeded check.

    (CCSHAU, 2016) Aashish Kumar; Kamboj, B.R.
    The present study entitled “Performance of maize hybrids under different planting methods in spring season”, was conducted in Yamunanagar district of Haryana during spring 2015. The soil of the experimental field was sandy loam, slightly alkaline in reaction, low in nitrogen, medium in phosphorus and high in potash. The experiment was conducted in split plot design with three replications which consists of three planting methods viz., ridge, flat and furrow methods of planting in main plots while five maize hybrids i.e. HM-4, HM-9, HM-10, HM-11 and HQPM-5 were kept in sub-plots. Growth parameters like plant height, dry matter accumulation and relative growth rate were found maximum under ridge method of planting followed by flat and furrow methods. The higher grain yield, stover yield, biological yield, net returns and benefit cost ratio were recorded with ridge method of planting than flat and furrow methods. However, different planting methods had no effect on quality parameters namely tryptophan, lysine, protein, nitrogen, zinc and iron content in maize grain. The periodic growth parameters viz., dry matter accumulation and relative growth rate were significantly higher with hybrid HM-10 over other maize hybrids. The hybrid HM-10 gave higher grain, stover, biological yield, net returns and benefit cost ratio. The quality parameters i.e. zinc and iron content was not affected by different maize hybrids but tryptophan and lysine content were maximum in hybrid HQPM-5, whereas nitrogen and protein content were highest in hybrid HM-4.

    (2016) Malik, Kapil; Mehta, Anil Kumar
    The present study entitled “Effect of spacing and nitrogen doses on productivity and quality of cotton (Gossypium hirsutum L.) cultivar H- 1098 (i)”, was conducted at cotton research station, Sirsa during Kharif 2015. The soil of the experimental field was loamy sand, slightly alkaline in reaction, low in organic carbon and nitrogen, medium in phosphorus and high in potash. The experiment was conducted in split plot design with three replications. The experiment consist of four spacing of cotton crop viz. S1= 67.5 cm × 10 cm , S2 = 67.5 cm × 15 cm , S3= 67.5 cm × 22.5 cm and S4 = 67.5 cm × 30 cm were kept in main plots while four levels of nitrogen i.e. 75%, 100%, 125%, and 150% application of the recommended dose were kept in subplots. Recommended dose of nitrogen was 87.5 kg ha-1. Maximum plant height and leaf area index was recorded with narrow spacing of 67.5 cm × 10 cm which was significantly higher than rest of spacing. However, wider spacing (67.5 cm × 30 cm) had lesser plant density resulted into higher dry matter accumulation, sympodial branches plant-1, number of bolls plant-1 and seed cotton yield plant-1. Whereas, seed cotton yield hectare-1, gross returns, net returns and B:C were maximum under 67.5 cm × 15 cm spacing. Nitrogen content in seed and plant was not affected due to different spacing but total uptake was maximum with spacing of 67.5 cm × 10 cm. Periodic growth parameters viz. plant height and leaf area index increased significantly with increasing levels of nitrogen up to 125% RD of nitrogen The dry matter accumulation plant-1 was significantly higher with 150% RD of nitrogen over rest of treatments. Number of sympodial branches plant-1 were significantly higher at 100% RD of nitrogen level than 75% RD of nitrogen which remained statistically at par with further increase in nitrogen levels. No. of bolls plant-1, seed cotton yield plant-1, seed cotton yield hectare-1, stick and biological yield increased significantly with 125% RD of nitrogen over 100% RD and 75% RD of nitrogen dose. The increase in nitrogen doses increased the N uptake in plant, seed and total uptake up to 125% RD of nitrogen. Highest gross returns, net returns and B:C was observed in 125% RD of nitrogen. Different spacing and nitrogen doses had no significant effect on quality parameters of cotton.

    (CCSHAU, 2016) Dahiya, Seema; Jagdev Singh
    A field experiment entitled “Performance of two rowed barley under various seed rate, spacing and nitrogen levels” was conducted during the rabi season of 2014-15 at Agronomy Research Farm of Chaudhary Charan Singh, Haryana Agricultural University, Hisar. The experiment consisted of two seed rates (87.5 and 100 kg/ha) and three spacings (22, 20 and 18 cm) in main plots and four nitrogen levels (60, 75, 90 and 105 kg N/ha) in sub plots. The 24 treatment combinations were tested in split plot design with three replications. Based on research investigation it was found that application of 100 kg/ha seed rate significantly improved plant stand, growth parameters, yield attributes except 1000- grain weight, yields, harvest index, protein yield, malt yield and nutrient uptake as compared to 87.5 kg/ha. However, quality parameters like bold grain (%), hectoliter weight, starch content, protein content, husk content, malt recovery (%) and nutrient content were statistically similar under both seed rates. Row spacing of 18 cm gave significantly higher number of grains per spike, grain yield, straw yield, malt yield and total uptake as compared to 22 cm but was at par with 20 cm. However row spacing of 18 cm was significantly superior in respect of plant stand, growth parameters, effective tillers, biological yield as compared to both 20 and 22 cm. Dry matter accumulation, LAI, number of tillers, all the yield attributes, grain yield, biological yield, protein yield, malt yield, N content and total NPK uptake increased significantly up to 90 kg N/ha. However, plant height and straw yield increased significantly up to 105 kg N/ha. At higher seed rate of 100 kg/ha, row spacing of 20 and 18 cm produced statistically similar yield whereas at 87.5 kg/ha seed rate 18 cm row spacing produced significantly more grain yield than 20 and 22 cm. Also straw and biological yield increased up to 105 kg N/ha with seed rate of 100 kg/ha, whereas at lower seed rate (87.5 kg/ha) the yield with 90 and 105 kg N/ha were statistically at par. Two rowed barley gave significantly higher net returns and benefit– cost ratio with 100 kg/ha seed rate, 80 cm row spacing and 90 kg N /ha.

    (CCSHAU, 2016) Mohammed Mohsin; Yadav, J.S.
    The present study entitled “Comparative Studies on Castor Based Intercropping Systems” was conducted with objectives to compare sole castor and castor intercropping in terms of productivity and to find out most suitable castor based intercropping system. For accomplishment of objectives of the study, a field experiment conducted during 2015-2016 at Regional Research Station, Bawal (Rewari), CCS Haryana Agricultural University. The field experiment was conducted in randomized block design, comprising of 15 treatments with sole castor, castor + greengram, castor + sesamum, castor + groundnut and castor + clusterbean under three level of row spacing of castor, viz. 120 cm, 180 cm and 240 cm. The results showed that significantly higher plant height and dry matter production per plant of castor were obtained when castor crop was sown as sole castor (240 cm). Sole castor (240 cm) recorded significantly higher number of spikes per plant, number of capsules per spike and number of primary branches per plant followed by castor (240 cm) + greengram (1:6) intercropping. Oil content and 100 seed weight of castor were not affected by different intercropping systems and row spacing of castor. The mean seed yield of sole castor (120 cm) was 5246 kg ha-1, which was more than rest of the treatments. The highest castor oil yield (2554 kg ha-1) was obtained when castor crop was sown as sole castor (120 cm). Significantly highest castor equivalent yield (6037 kg ha-1) was obtained in castor (180 cm) + groundnut (1:4) closely followed by castor (240 cm) + greengram (1:6) intercropping system. Net return were greater when castor was intercropped with greengram either in 1:6 (Rs. 121455 ha-1) or 1:2 (Rs. 119986 ha-1) row proportion. The benefit : cost ratio was highest with castor (240 cm) + greengram in 1:6 row proportion (1.79) and castor (180 cm) + greengram in 1:2 row proportion (1.75).

    (CCSHAU, 2016) Kapoor, Anil; Ishwar Singh
    A field experiment was conducted during kharif 2015 at Rice Research Station, Kaul (Kaithal) of CCS Haryana Agricultural University, Hisar to study the effect of different dates of transplanting on growth, yield, quality and economics of non scented rice varieties. The experiment comprised three dates of transplanting viz. June 15, July 05, and July 25 in main plots and four non scented rice varieties viz. HKR-48, HKR-47, HKR-127 and HKR-128 in sub plots conducted in split plot design with four replications. Experimental soil was clay loam in texture alkaline in reaction having high pH (8.1), low in organic carbon (0.32 %), low in N (161 kg/ha), medium in P (16.2 kg/ha) and high in K (328.2 kg/ha). The early transplanted crop (June 15 and July 05) recorded significantly higher number of tillers, dry matter accumulation, leaf area, CGR, RGR, yield and yield attributes than late transplanted crop (July 25). But late transplanted crop (July 25) gave higher hulling, milling and head rice recovery than early transplanted crop. The two early dates (June 15 and July 05), being at par, were significantly superior to July 25 in respect of grain yield. The interaction between dates of transplanting and non scented varieties of rice was found significant which revealed that the reduction in grain yield about 30 per cent when delay in transplanting from June 15 to July 25. The extent of reduction in grain yield was less (23%) in early duration variety HKR-48 than mid early duration variety HKR-47 (30%) and medium duration varieties HKR-128 (31%) and HKR-127 (32%) when time of transplanting delayed from June 15 to July 25. The medium duration variety HKR-128 was superior in respect of all parameters than HKR-127, HKR-47 and HKR-48. HKR-128 recorded significantly higher yield (69.67 q/ha) than HKR-127 (66.04 q/ha), HKR-47 (63.82 q/ha) and HKR-48 (52.65 q/ha). The maximum net return (Rs. 24020/ha) and B:C (1.27) was obtained by June 15 transplanting followed by July 05 (Rs. 22305/ha and 1.25, respectively) and July 25 (Rs. -10403/ha and 0.88, respectively). The HKR-128 gave the highest net return (Rs. 22640/ha) and B:C (1.25) as compared to other varieties.

    Studies on response of kharif maize to different plant nutrients
    (CCSHAU, 2016) Harender; Samar Singh
    An experiment was conducted during Kharif 2015 at Regional Research Station, Karnal of CCS Haryana Agricultural University to study the effect of different applied nutrients on growth, yield and yield attributes and uptake of nutrients by maize. The experiment comprised twelve treatments viz.T 1 : Control (No fertilizer), T2 : N (@ 150 kg N ha -1 ), T3 : T2 +P (@ 60 kg P 2O5 ha -1 ), T4 : T3 +K (@ 60 kg K 2 O ha -1 ), T5 : N+P+K+ S (@ 160, 60, 60 + 40 kg ha -1 ), T6 : T4+ Zn (@ 25 kg ZnSO 4 ha -1 ), T7 : T4 + Fe (two foliar spray of 1% FeSO 4 ha -1 ), T8 :T4+Mn (two foliar spray of 0.5% MnSO 4 ha -1 ), T9: T 4 +S+Zn, T 10 : T9 +Fe, T 11 : T10 +Mn and T 12: Soil test based fertilizer application. The trial was conducted randomized block design (RBD) with three replications. Experimental soil was sandy clay loam in texture having high pH (8.2), medium in organic matter (0.46 %), low in N (120 kg/ha), high in P (15 kg/ha) and high K (127 kg/ha). Soil contained sufficient amount of micronutrients (Fe, Mn and Zn). The observation were recorded on plant stand, growth parameters, days to 50 per cent tasseling and silking, yield and yield attributing characters, uptake of nutrient by plants, quality and economics of maize. The application of N over control (51.2 q/ha), NP over N alone (56.5 q/ha) and NPK over NP (71.8 q/ha) significantly increased the maize yield. The application of N over control, NP over N and NPK over NP in increased the grain yield by 10.3%, 27.0% and 25.1%, respectively. The treatments of application of NPK with or without micronutrients (Fe, Mn and Zn) were at par in case of growth, yield and yield attributes of maize. Maximum grain yield (73.4 q/ha) was obtained from the treatment of NPK+S followed by the treatment of NPK+Zn (72.8 q/ha) and application of nutrients on soil test based (71.4 q/ha) and minimum in control treatment (40.9 q/ha). Addition of micronutrients significantly increased their uptake in maize plants compared to alone application of major nutrient (N, P and K). Protein content (11.0 per cent) and protein yield (8.1q/ha) was found maximum in the treatment of NPK+S. The application of N over control, NP over N alone, NPK over NP and NPKS over NPK increased the farmer profit even after additional costs of inputs. The application of macronutrients (NPK+S) gave maximum (net returns Rs.48705/- and B-C ratio 1.83) followed by the treatment of NPK+Fe (net returns Rs.47410/- and B-C ratio 1.81) and minimum with control treatment (net returns Rs.10071/- and B-C ratio 1.20).
