Phosphorus is the most common nutrient which helps the plants to convert metabolites into usable building blocks for growth. The use of phosphate solubilising bacteria as inoculants simultaneously increases P uptake by the plants and hence improves crop yield. Strains from the genera Pseudomonas, Bacillus and Rhizobium are among the most powerful Phosphate solubilisers. The principal mechanism for mineral phosphate solubilisation is the production of organic acids. Acid phosphatase plays a major role in the mineralization of organic phosphorous in soil. Several phosphatase encoding genes have been cloned and characterized. A few genes involved in mineral phosphate solubilisation have been isolated. Therefore, genetic manipulation of phosphate solubilising bacteria can improve plant growth. Synergistic effect of phosphate solubilising microorganisms on TCP solubilisation was highest when triple culture of Aspergillus niger, Aspergillus flavus and Trichoderma sp. was inoculated in NBRIP broth as compared to double and single inoculations.

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.

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.

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。

White yam (Dioscorea rotundata Poir) is grown as a major food crop in tropical countries. It is emerging as an important tuber crop in India especially in Kerala and it is well known for its yield potential. ICARCentral Tuber Crops Research Institute holds a field gene bank of 1100 Dioscorea accessions including 158 white yam genotypes. Genetic variability in plants can be used for developing improved cultivars with desirable traits. Present study focused on identifying genetic variability in 30 white yam genotypes (Dwarf, Semi dwarf and Tall) using 19 random oligonucleotide primers for RAPD analysis. On 19 RAPD primers, only 8 primers were selected based on their polymorphism and repeatability. Among the eight RAPD primers studied in white yam, OPW -16 was found be the best that produced ten polymorphic bands. All the primers evaluated resulted in 100% polymorphism. All the primers were recorded with high PIC value of >0.6. Dendrogram based on RAPD marker showed nine clusters at 0.8 dissimilarity level. It also shows the high divergence of the genotype V20 (DR17) and the clustering pattern indicates the grouping of the dwarf genotypes together. More or less similar clusters were obtained based on certain morphological characteristics of the genotypes observed in the field study.

The beneficial effects of Brassica vegetables on health improvement have been partly attributed to the presence of various forms of phytochemicals and antioxidants present in it, e.g. ascorbic acid, carotenoids and polyphenol compounds including flavonoids and chlorophyll. Two Brassica vegetables viz. broccoli (Brassica oleracea) and kale (Brassica oleraceae l.var acephala) which, grown organically and conventionally were analysed for their phytochemicals content. The ascorbic acid content of organically grown broccoli and kale was 89.67±0.33 and 48.67±0.33 mg/100g which was comparatively higher when compared with inorganic counterparts with 84.80±0.40 and 43.33±0.67 mg/100g values respectively. The beta carotene content was found to be higher in case of organic broccoli i.e. 11.17±0.01 ppm as compared to 8.71±0.01 ppm in inorganic broccoli. The chlorophyll content was higher in case of inorganic broccoli (5.87±0.03 mg/L) and kale (8.31±0.01 mg/L). Simple phenol and flavanoids were found to be higher in case of organic kale as compared to inorganic kale. Total phenols, tannins and oxalates were found to be higher in inorganic broccoli and kale. Both broccoli and kale were good sources of pytochemicals. From the findings of the study concluded that they are rich in health–promoting phytochemicals so should be included in our food basket to provide protection against various diseases especially cancer. The cultivation and consumption of broccoli and kale should be promoted to harness their health promoting and health protecting beneficial effects. The phytochemical contents of the leafy vegetables serve as supplements for food and also have the potential to improve the health status of its users as a result of the presence of various compounds vital for good health.
