A field experiment was conducted at the College Farm, N. M. College of Agriculture, Navsari Agricultural University, Navsari to study the effect of spacing and cobalt application on kabuli chickpea (Cicer kabulium L.) cultivars. The treatments of the study included eighteen treatment combinations consisting of three varieties. Two spacing and three-cobalt application methods were evaluated by using factorial randomized block design (FRBD) with three replications. Significantly highest nodule number plant-1 (56.02), nodule fresh (2.61 g) and dry weight (0.25 g), seed yield (1497.07 kg ha-1), stover yield (2243.87 kg ha-1) were achieved with variety PKV2 (V3) followed by variety Kripa. The variety Kripa (V2) recorded numerically higher harvest index (40.39). The crop sown at spacing 60×10 cm2 (S2) produced maximum number of nodules plant-1 (53.64), nodule fresh (2.50 g) and dry weight (0.23 g) but only dry weight of root nodules was found at par with 45×10 cm2 spacing (S1) (0.21g). Significantly higher seed and stover yield (1274.51 and 2191.95 kg ha-1) and Harvest index (42.16%) were obtained with spacing 45×10 cm2 (S1). In case of cobalt application methods, significantly highest number of root nodules plant-1 (54.31), maximum fresh (2.54 g) and dry weight (0.25 g) of nodules, seed and stover yield (1520.51 and 2249.40 kg ha-1) were obtained under application of cobalt as foliar spray at 0.01%.

Apple (Malus×domestica) is commercially most important horticultural crop grown in the north-western Himalayan region of India. The apple scab caused by fungi Venturia inaequalis (Cooke) Wint., is a devastating disease of apple aided by cool, moist climate during early spring. The present study on evaluation of effective fungicides against apple scab was undertaken in Himachal Pradesh during the years 2016 and 2017 under natural epiphytotic conditions. The application of carbendazim 25%+flusilazole 12.5% SE (0.08%) significantly decreased the apple scab disease in the present study. This resulted in maximum reduction of per cent conidia and conidial germination of V. inaequalis at the concentrations tested. It was superior and effective in comparison to other fungicides. Since the new combination of carbendazim 25% + flusilazole 12.5% SE exhibits systemic activity and both the fungicides have different modes of action, therefore, such a new combination can delay or prevent the build-up of resistance in the pathogen and can be effectively utilized as a promising fungicide for the control of apple scab disease.

The present study was aimed to detect and identify seed borne fungi associated with soybean seeds and subsequently determining their effect on seed germination and seedling growth. Seed mycoflora associated with soybean were detected by using agar plate and standard blotter paper method. A total of six fungal species comprising three genera i.e., Aspergillus flavus, Aspergillus niger, Aspergillus versicolor, Fusarium oxysporum, Fusarium pallidoroseum and Macrophomina sp. were isolated from soybean seed. Among these, Fusarium pallidoroseum and Aspergillus flavus were found to be the most prevalent causing considerable reduction in seed germination and seedling growth as compared to control. The effect of different bio-agents and phyto-extracts on seed mycoflora, seed germination and vigour index were evaluated. Trichoderma viride and Dhatura leaf extract were found to enhance seed germination, shoot length, root length and vigour index as compared to control.

Pre-sowing hardening or priming of seeds is one of the best methods for altering the biochemical and physiological process of seeds for favourable condition to induce drought tolerance in emerging seedlings. The recurrent phenomenon in rainfed areas i.e. soil moisture stress immediately after sowing affects seeds germination and their establishment. Under sub-optimal environmental conditions like rainfed farming, poor seed germination followed by poor field establishment is a common phenomenon. Seed hardening enables seedlings to survive this early moisture stress. hydration of seeds for short term before planting greatly benefits stand establishment along with the uses of chemicals like potassium or sodium phosphate would give additional advantage. It is defined as the process of soaking seeds in chemical solution for specified time and then drying to induce tolerance to drought. Various seed priming/hardening techniques have been developed including hydro-priming, halo-priming, osmo-priming and hormonal priming. Micronutrient seed treatments, which include seed priming and seed coating, are an attractive and easy alternative. Seed hardening promotes early establishment provides more strengthen to plant and it became competitive against infections and diseases is related to gene regulation and expression under stress conditions. The discovery of plant hormones in the 1920s underlined the crucial role of these compounds in seed desiccation tolerance, reserve mobilization, as well as cell division and cell elongation occurring during germination. The seed hardening is considered as low cost technology and is the most important requirement for pre-monsoon sowing. Seed hardening offer an attractive option for resource poor farmers. During seed hardening, seeds are subjected to partial hydration followed by dehydration before sowing.

Majority of the leaf spot diseases on soybean crop is caused by different pathogenic fungi. Under favourable conditions and severe infection, it may result in heavy defoliation. It decreases the production efficiency of the crop by reducing the surface area available on leaves for photosynthesis. With less photosynthetic activity, the yield may be reduced significantly. Thus, making it a production constraint by reducing the economic viability of the infected soybean crop. Cercospora leaf spot, Target leaf spot, Alternaria leaf spot, Brown Spot, Phyllosticta leaf spot are the major leaf spots caused due to fungus in the soybean crop worldwide. In this review, we are discussing about economic importance, symptomatology, causal organism, disease cycle, epidemiology and integrated management of leaf spots caused due to fungal infection in the soybean crop.

Thus, making it a production constraint by reducing the economic viability of the infected soybean crop. Cercospora leaf spot, Target leaf spot, Alternaria leaf spot, Brown Spot, Phyllosticta leaf spot are the major leaf spots caused due to fungus in the soybean crop worldwide. In this review, we are discussing about economic importance, symptomatology, causal organism, disease cycle, epidemiology and integrated management of leaf spots caused due to fungal infection in the soybean crop.","PeriodicalId":13829,"journal":{"name":"International Journal of Economic Plants","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-02-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"87883654","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}
