Grain and biomass yields and harvest index of pigeonpea did not vary significantly among the agroforestry systems. However, significantly lower grain (1192 kg ha-1) and biomass (5563 kg ha-1) yields of pigeonpea were recorded at 5 m distance away from the neem tree line (P=0.05) compared to the distances of 10 m ( 1450 and 6942 kg ha-1, respectively) and 15 m (1449 and 6720 kg ha-1, respectively) away from the tree line. Significantly higher grain yield (1520 kg ha-1) was observed in control without any proximity of trees compared to the agroforestry systems which accounted for a mean reduction of 11 per cent in yield. Among different agroforestry systems, significantly higher tree height was recorded in bund planting (7.61m) followed by boundary planting (7.38 m) and scattered planting (6.46 m) whereas the crown spread recorded was significantly lower in bund planting (6.27 m) followed by scattered planting (6.38 m) and boundary planting (6.68 m). There also existed non-significant difference in girth, volume and biomass of neem trees grown in different agroforestry systems. Further, the physicochemical properties of soil were found improved in agroforestry systems compared to control and the trend varied among the different agroforestry systems","PeriodicalId":18181,"journal":{"name":"Legume Research","volume":"39 1","pages":"87-92"},"PeriodicalIF":0.8,"publicationDate":"2018-05-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"73966436","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Ten-day-old seedlings, grown hydroponically, were treated with 0, 25, 50, 75, 100, 125 and 150 mM NaCl for 7 days and analysed for the traits as biomarkers for identification of salt-tolerant soybean genotype. It was observed that NaCl stress caused severe impairments in photosynthetic rate, chlorophyll fluorescence and chlorophyll content in both the genotypes, but the damage were much more pronounced in salt-sensitive genotype VL SOYA-47. Moreover, chlorophyll fluorescence measurements showed higher non-photochemical quenching in genotype VL SOYA-47 and lower in genotype VL SOYA-21. The antioxidant enzyme activities (superoxide dismutase, catalase, ascorbate peroxidase and glutathione reductase) was observed much higher in VL SOYA-21 than in VL SOYA-47 at various levels of NaCl treatments. From the results, it could be suggested that VL SOYA-21 is the salt tolerant and VL SOYA-47 is a salt sensitive soybean genotype. The tolerance capacity of VL SOYA-21 against NaCl stress can be related with the ability of this genotype in possessing vital photosynthetic system and ROS scavenging capacity.","PeriodicalId":18181,"journal":{"name":"Legume Research","volume":"32 1","pages":"551-556"},"PeriodicalIF":0.8,"publicationDate":"2018-05-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"88871951","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Results of on farm trials revealed significant impact of adoption of management techniques of biotic stresses on seed yield, net profit and benefit cost ratio as compared to existing practices of pigeon pea cultivation. Scientific management of weed, pod borer and wilt was increased in seed yield by 26.2, 46.1 and 12.2%, while saving of seed by 23.6% from bruchids compared with existing practice, respectively. Among biotic management practices, higher additional cost was observed on weed management (Rs. 2,974 ha-1) and it was minimum on pod borer management (Rs. 798 ha-1) compared with existing practices. Accordingly, additional maximum net returns were obtained with pod borer (Rs. 24,805 ha-1) and minimum with wilt (Rs. 9,401 ha-1). Interventions of biotic stresses management were significantly influenced the output, use-efficiency, productivity and net gains of energy compared to existing practices. Maximum additional net energy gain was in management of weed (25,649 MJ ha-1) followed by pod borer (13,349 MJ ha-1), bruchid (8,390 MJ ha-1) and wilt (5,325 MJ ha-1). After harvest of second crop of pigeon pea, organic carbon, bulk density, infiltration rate and available N, P, K, S and Zn were significantly increased with weed and wilt management over existing practice. Management of biotic stresses by proper technologies increased the productivity of pigeon pea of three folds (2.12 to 2.33 t ha-1) compared to its average productivity of India and also increased economic benefits and energy outcomes.","PeriodicalId":18181,"journal":{"name":"Legume Research","volume":"7 1","pages":"61-67"},"PeriodicalIF":0.8,"publicationDate":"2018-05-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"83028644","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Significant variation was observed by the way of analysis of variance for nine characters viz., days to 50% flowering, days to maturity, plant height, number of branches per plant, pod bearing length, number of pods per plant, number of seeds per pod, seed yield per plant and hundred seed weight. Molecular diversity using 18 polymorphic simple sequence repeat (SSR) markers divided genotypes into 15 clusters, of which ICP11059 and AK-101 were solitary, indicating their distinctiveness among all genotypes. Similarly, BSMR-533, JKM-7, RVK-285, ICP-1126, ICP-348, ICP-6859 and ICP-7869 were found distinct among the genotypes. Geographical origin based diversity separated Indian and non Indian genotypes. The Un weighted Pair Group Method with Arithmetic mean (UPGMA) based dendrogram indicated distinctiveness of ICP-13633 and Bennur local, as they formed solitary cluster. The SSR marker CcM 602, as it could differentiate 4 genotypes at different base pair size can be used for identification and finger printing of genotypes.","PeriodicalId":18181,"journal":{"name":"Legume Research","volume":"33 1","pages":"32-38"},"PeriodicalIF":0.8,"publicationDate":"2018-05-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"78225211","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
