Nutrient management is one of the major problem of the sodic land due to low organic matter status and toxicity of sodium, which reduced the availability of other nutrients and affects the soil properties. A field experiment was conducted to evaluate the integrated nutrient management options in sodic soil at Shivali Village of C.S.A. University of Agriculture and Technology, Kanpur during 2005-06 and 2006-07. The physico-chemical properties of the soil were pH(2.5) - 8.9, EC(2.5) - 0.61 dS/m, organic carbon - 3.6 g/kg, CaCO3-1.24%, GR-7.92 t/ha, sand-56%, silt- 28%, clay-16% (sandy loam), available N-156 kg/ha, available P-25.3 kg/ha, available K-235 kg/ha and available Zn-0.78 ppm. Results indicated that plant height, fertile tillers, biomass/hill, length of ear, test weight, grain and straw yield of rice (Oryza sativa L.) and wheat {Triticum aestivum (L.) emend. Fiori & Paol} significantly increased by application of fertilizer on the soil test basis in comparison to farmers practice. Further increased the yield and yield attributing characters when organic manures (FYM, pressmud and NADEP compost) added @ 5 t/ha with the recommended doses of fertilizers. Application of organic manure (FYM) integrated with recommended dose of fertilizers and biofertilizers (PSB + BGA/ Azotobacter) further increased the yield and yield attributing characters of rice and wheat which was similar to 125% recommended dose of fertilizers. The maximum grain yield of rice and wheat (5.46 and 3.57 t/ha) was recorded with application of NPKZn based on soil test + FYM @ 5 t/ha + PSB + BGA. Similar trends were also recorded in case of nutrient uptake. In case of microbial populations, maximum bacterial population (94.0 × 105/g soil) and Azotobacter (51.5 × 102/g soil) was recorded with application of NPK Zn based on soil test + FYM @ 5 t/ha + PSB + BGA and maximum PSB count (42.0 × 102/g soil) was recorded in with application NPK Zn based on soil test+PSB+BGA. The Actinomycetes population was not affected by the different treatments. Improvement in soil properties (pH, EC, OC) and soil fertility status (NPK and Zn) was recorded when chemical fertilizers were integrated with organic manures. Source

Genetic analyses were carried out of 28 genotypes (7 Parents + 21 F1s) through diallel mating design excluding reciprocals in bread wheat. Analysis of variance reflected appreciable variability among the parents as well as among the crosses for almost all the characters. Component analysis revealed that dominance gene action was prevalent in most of the traits. High estimates of heritability (h2) and genetic advance were found only for duration of reproductive phase. Rest of the traits exhibited differential combinations. Grain yield per plant was significantly correlated with number of productive tillers per plant, spike length, biological yield, harvest index and test weight. In path coefficient analysis, higher desirable direct effects were observed for grain yield in biological yield, harvest index and duration of reproductive phase, indicating the high value of selection parameters should be given due importance during selection.

Screening of germplasm/varieties was made to find out the sources of resistance against F. oxysporum f. sp. lini. Screening was conducted on 78 available germplasm/varieties during 2003-2004 and 2004-2005 in rabi season of linseed under natural conditions. Out of total 78 entries, 27 cultures were found to be resistant to disease as the disease incidence in these cultivars were between 0 and 10%. Twenty-three cultivars fell in moderately resistant category with 10.1-25% wilt incidence. Nine genotypes were found moderately susceptible sho'wing 25.1-50% disease incidence, 14 genotypes were found susceptible showing 50.1-75% and 6 genotypes were found highly susceptible to disease (above 75%). © 2012 Copyright Taylor and Francis Group, LLC.

Studies on population dynamics of different fruit flies, by using locally made methyl eugenol (ME) traps were conducted at five locations of Kanpur district, (U.P.). The incidence of fruit flies was correlated with weather data. Three species viz. Bactrocera dorsalis (Hendel), B. zonata (sounders) and B. correcta (Bezzi) were captured in the ME Traps, of which B. correcta was predominant followed by B. zonata and B. dorsalis. On population of B. correcta, temperature had a positive correlation at three places viz. horticulture orchard, vegetable farm and IIPR while at two places it had negative correlation (r = -0.034 and 0.2811) i.e. at insectary and Vishnupuri, respectively. Relative humidity was negatively correlated at four locations while it showed positive correlation at IIPR (r = 0.273). Rainfall had a positive correlation with catches of B. correcta at three locations while it showed positive correlation at two places. B.zonata and B. dorsalis had a positive correlation with temperature mostly. Source

Indian mustard [Brassica juncea (L.) Czern & Coss.] is a long day plant, which requires fairly cool climatic condition during growth and development for obtaining better seed yield. Various workers have correlated crop growth and development with energy requirement parameters, such as growing degree days (GDD), photo-thermal unit (PTU), helios thermal unit (HTU), photo-thermal index (PTI) and heat use efficiency (HUE). Therefore, GDD requirement for different phenological stages of 22 newly developed Indian mustard varieties was studies during winter (rabi) seasons of 2009–10 and 2010–11 at student instructional farm of C.S. Azad University of Agriculture and Technology, Kanpur, (Utter Pradesh). Study revealed that RH-8814, NRCDR-02 and BPR-549-9 recorded higher GDD (1703.0, 1662.9 and 1648.0), PTU (19129.8, 18694.2 and 18379.8), HTU (11397.7, 11072.2 and 10876.0), PTI (13.25, 13.14 and 13.08) and HUE (4.11, 3.84 and 3.71) at physiological maturity, while higher HUE was recorded (9.62, 8.99 and 8.91 kg ha−1 degrees-day) at days after sowing (DAS) to 50 % flowering. On the basis of study mustard genotypes RH-8814, NRCDR-02 and BPR-549-9 were identified as most heat-tolerant, as they maintained higher values for energy related parameters. Seed yield was highly positively correlated with GDD (r = 0.61, 0.65 and 0.75), PTU (r = 0.66, 0.64 and 0.74), HTU(r = 0.79, 0.68 and 0.73) at the above these three phenological stages, while negatively correlated with PTI at anthesis and at maturity. Hence, these parents could be used in crossing programme for achieving further improvement. © 2014, The Author(s). Source
