The present study was undertaken to isolate Rhizobium leguminosarum strains from the nodules of Pea (Pisum sativum (L)) var AP-3 grown in the soil of Hoshiarpur. These isolated nitrogen fixing strains were also tested for their tendency to solubilize Tricalcium Phosphate (TCP) on Pikovskaya (PVK) agar, Modified Pikovskaya (MPVK) agar and National Botanical Research Institute (NBRIP agar). The halo size of R. leguminosarum SS-8 was reported to be biggest (13 mm) on NBRIP agar and the smallest (4 mm) in PVK agar. These strains were further inoculated in PVK and NBRIP broths, respectively to see their potentials to solubilize TCP. The strain R. leguminosarum SS-8 was observed to show maximum TCP solubilisation (261 μg/ml in NBRIP and 211 μg/ml in PVK broths) with maximum decrease in pH (4.14 in NBRIP and 4.20 in PVK

The aim of the present study was compensating nitrogen fertilizer requirement of desi wheat by vermicompost and Azotobacter. The experiment was conducted during the rabi season of 20172018 at the Agronomy Research Farm of Chaudhary Charan Singh Haryana Agricultural University, Hisar. 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 yield attributing characters like number of grains per spike, number of spikelets per spike and spike length, grain, straw and biological yield of desi wheat. But various treatments failed to produce any significant variation in 1000 grain weight of desi wheat.

The present investigation was carried out during 2015-2016 at Vegetable Research center, G.B. Pant University of Agriculture and Technology, Pantnagar . The trial was conducted to know the seasonal population dynamics of whitefly and aphid in tomato (Lakshmi hybrid1) and their relation to weather parameters. The results found that incidence of the Bemisia tabaci occurred from 39 th standard meteorological week (SMW) 2015 to 7 th standard meteorological week. Maximum population of whitefly was recorded during first week of October with incidence upto the last week of May. Simple correlation worked out between the weather parameters and the population of Bemisia tabaci revealed that there was non-significant negative correlation with morning relative humidity, rainfall, sunshine hours, maximum and minimum temperature but significant negative correlation with evening relative humidity. However, wind velocity exhibited a positive non-significant correlation with whitefly population during crop season while the incidence of the aphid spp was noticed from 40 th standard meteorological week (SMW) 2016 to 7 th standard meteorological week 2016. Persistent high population was noticed from 40 th to 43 rd (SMW) Simple correlation worked out between the weather parameters and population of Aphis gossypii revealed that there was non significant positive correlation with maximum and minimum temperature and sunshine hour, while maximum relative humidity, wind velocity, rainfall and minimum relative humidity showed non significant negative correlation with aphid population during crop season 2015-2016.

A study was conducted in the experimental farm of SASRD, Nagaland University during Kharif 2017 in order to screen soybean genotypes for resistance against major insect pests using two replications. Forty one soybean genotypes along with five check varieties were arranged in RBD. The major insect pests observed at weekly intervals were leaf webber (Anarsia ephippias), aphid (Aphis glycines), leaf hopper (Bothrogonia indistincta), Pod bug (Riptortus pedestris) and blister beetle (Mylabris phalerata). The genotypes NRC 134 (4.20 no/mrl) and JS 20-17 (0.70 no/mrl) showed highest and lowest infestation by leaf webber. Highest infestation of aphid was found on PS 1613 (21.85no/3leaf) and lowest was found on AMS 100-39 (1.50 no/3leaf). In case of leaf hopper, the highest infestation was found on NRC 137 (4.75no/3leaf) and the lowest infestation was found on DSb 34 (1.08 no/3leaf). Genotypes namely NRC 137 (5.88 no/mrl) showed highest infestation and genotype JS 21-15 (1.23 no/mrl) showed lowest infestation by blister beetle. For pod bug, genotype CSB 10112 (5.90 no/mrl) showed highest infestation and NRC 128 (0.12 no/mrl) showed lowest infestation. The highest yield was reported by TS 53 (3155 kg/ha) and lowest was NRC 131 (488.88 kg/ha). Cluster analysis was used to group line based on five major soybean insect pests (leaf webber, aphid, leaf hopper, blister beetle and pod bug) infestation levels within the site and found that Cluster V (TS 53, SL 1123, SKF-SPS-11) was considered the resistant cluster with highest yield, where the best performing genotypes were included.

In the present investigation, various treatment combinations were optimized for the preparation of papaya fruit flakes. For the standardization of papaya cereal flakes three different recipes were tried with various combinations of papaya pulp, maida flour (100 %), corn flour (100 %), maida flour and corn flour in combination (70:30) for the development of papaya cereal flakes. Papaya cereal flakes prepared by using different combinations of both flours were compared on the basis of sensory evaluation with standard recipe in which maida was used. Papaya cereal flakes (T3) prepared using papaya pulp2.5 Kg, maida and corn flour in 70:30 ratio -(220.5 +94.5) g, sucrose150 g, glucose-150 g, pectin3.65 g, water250 ml, CaCO3-3 g was rated best on the basis of sensory evaluation. Further the prepared product were packed in aluminium laminated pouches and stored for 6 months under ambient temperature conditions. The various quality characteristics such as moisture, total soluble solids, titratable acidity, ascorbic acid, total sugars, reducing sugars, ash, fibre and carotenoids, were analyzed at 0, 3 and 6 months interval. The stored papaya-cereal flakes had better quality in terms of color, flavor, texture, overall acceptability and also have better retention of all quality characteristics at ambient temperature conditions. Thus papaya-cereal flakes could be stored successfully without any significant changes in quality characteristics at ambient temperature conditions for 6 months in aluminium laminated pouches.

This paper analyzes the management of soil organic matter is critical to maintain a productive organic farming system. No one source of nutrient usually suffices to maintain productivity and quality control in organic system. In addition, the inputs to supplement nutrient availability are often not uniform presenting additional challenges in meeting the nutrient requirement of crops in organic systems. With this concept, a field experiment was conducted at village Jahangirpur in Jewar Tehsil in Gautam Buddha Nagar district of Uttar Pradesh during 2014-2016 in rice-wheat cropping system. In this experiment, different treatments comprising organic amendments such as Blue Green Algae (BGA) 15kg/ha, SGM 10.0 tonne/ha, and Farm Yard Manure (FYM) 10.0 tonne/ha each applied alone or in combination were tested in organic crop production. These treatments were compared with absolute control (N0P0K0). For rice, a scented variety ‘Pusa Basmati 1’ were taken. The observations on grain yield, contents of Fe, Zn, Mn and Cu in rice grains, insect pest incidence, soil nutrients and microbial activity were taken. Results revealed a significant enhancement in grain yield of rice over absolute control due to the application of different organic amendments applied alone or in combinations. Rice grain yield increased by 114 to 116.8% over absolute control when all the 4 organic amendments were applied altogether. The rice grain yield (4.0 t ha-1) obtained under combined application of four organic amendments was at par with the yield recorded under recommended dose of chemical fertilizer application. An interesting observation recorded was that there was no serious attack of any insect pest or disease in organically grown crop. Soil microbial population (Actinomycetes, Bacteria, Fungi and BGA) enhanced due to the application of organic amendments in comparison to absolute control application that in turn resulted in a notable enhancement in soil dehydrogenase and phosphatase enzyme activity. Soil organic carbon and available phosphorus contents were also found to be significantly increased due to organic farming practice over control. Rice grain analysis for nutrients viz. Fe, Zn, Mn and Cu showed a significant increase in Fe and Mn content in the treatments having 2 or more organic amendments over control. Zn and Cu content also increased but the increment was significant with combined application of 2 or 3 organic amendments. The study revealed that addition of three organic amendments viz. BGA, SGM, and FYM could give the optimum yield (4.05 t/ha) of organic Basmati rice and improve grain and soil quality.
本文分析了土壤有机质的管理是维持有机农业高产的关键。在有机系统中,通常没有一种营养来源足以维持生产力和质量控制。此外,用于补充养分有效性的投入往往不统一,这在满足有机系统中作物的养分需求方面提出了额外的挑战。2014-2016年,在北方邦Gautam Buddha Nagar地区Jewar Tehsil的Jahangirpur村进行了水稻-小麦种植系统的田间试验。在本试验中,分别单独或联合施用蓝绿藻(BGA) 15kg/ha、SGM 10.0 t /ha和农场厩肥(FYM) 10.0 t /ha等不同有机改良剂,对有机作物生产进行了试验。将这些处理与绝对对照(N0P0K0)进行比较。至于大米,则采用了一种有香味的品种“Pusa Basmati 1”。对水稻产量、籽粒铁、锌、锰、铜含量、害虫发生率、土壤养分和微生物活性进行了观察。结果表明,与绝对控制相比,单独或联合施用不同有机改良剂对水稻产量有显著提高。同时施用4种有机改良剂,水稻产量比绝对对照提高了114 ~ 116.8%。4种有机改良剂配施水稻籽粒产量(4.0 t hm -1)与化肥推荐用量下记录的产量相当。一个有趣的观察记录是,没有任何害虫或疾病的严重袭击有机种植的作物。土壤微生物数量(放线菌、细菌、真菌和BGA)的增加是由于施用有机添加剂而不是绝对对照,从而导致土壤脱氢酶和磷酸酶活性的显著提高。土壤有机碳和速效磷含量也因有机耕作方式而显著高于对照。水稻籽粒铁、锌、锰、铜营养物质分析表明,有机改性2种及以上处理的铁、锰含量显著高于对照。Zn和Cu的含量也有所增加,但2种或3种有机改进剂联合施用时增加幅度较大。研究表明,添加BGA、SGM和FYM 3种有机改良剂可使有机巴斯马提水稻获得最佳产量(4.05 t/ hm2),并改善籽粒和土壤质量。

Soil organic carbon and available phosphorus contents were also found to be significantly increased due to organic farming practice over control. Rice grain analysis for nutrients viz. Fe, Zn, Mn and Cu showed a significant increase in Fe and Mn content in the treatments having 2 or more organic amendments over control. Zn and Cu content also increased but the increment was significant with combined application of 2 or 3 organic amendments. The study revealed that addition of three organic amendments viz. BGA, SGM, and FYM could give the optimum yield (4.05 t/ha) of organic Basmati rice and improve grain and soil quality.","PeriodicalId":14249,"journal":{"name":"International Journal of Pure & Applied Bioscience","volume":"18 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2019-10-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"81563654","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
In the present study, characterization of 21 local rice genotypes was carried out for 16 DUS characters. The leaf and leaf sheath anthocyanin coloration was absent in all the genotypes. A total of eight traits viz., leaf pubescence of blade surface, leaf length of blade, leaf width of blade, flag leaf, panicle awns, panicle presence of secondary branching, panicle secondary branching and panicle exertion were dimorphic. Three traits basal leaf sheath colour, leaf intensity of green colour, culm attitude were found to be trimorphic. Remaining three traits namely flag leaf attitude of blade, panicle curvature of main axis and panicle attitude of branches were found to be tetramorphic. The genotype mundamaranellu was found to be distinct for erect culm, erect flag leaf and presence of awns and these genotypes can be used as donor for rice breeding program. The cultivars Thondi and mullampunchan (106 days) were found to be early on days to 50% flowering among all the genotypes evaluated. All genotypes exhibited significant differences for eight quantitative traits. The high PCV and GCV was recorded for plant height, number of productive tillers and single plant yield. The highest heritability and high genetic advance as per cent of mean was observed in plant height, number of panicles per plant, number of productive tillers, 1000grain weight, single plant yield and these characters could be further improved by following simple selection procedure.
