The present investigation was conducted with aim to isolate and characterize phosphate solubilizing bacteria from calcareous soil. Four efficient PSB isolates were obtained from fourteen soil samples collected from different locations. Based on morphological and biochemical characterization, highly phosphate solubilizing isolates were identified as Pseudomonas fluorescence, Bacillus subtilis, Bacillus thuringiensis and Pseudomonas aeruginosa respectively. The amount of Pi released from TCP by the isolates at 10 DAI ranged from 23.2 to 30.5 % and zone of solubilization recorded between 6 -13 mm. Among them PSB isolate 1 (Pseudomonas fluorescence) recorded highest Pi released from TCP broth i:e (30.5 %) and zone of solubilization recorded (13 mm) than the other isolates tested.

Aim: The Amrapalii cultivar of mango is known for its dwarf stature, high productivity and ability to capture the market late when mango from other regions of the country gets over. Vivipary is of unusual occurrence in mango. The aim of the study is to report the occurrence of vivipary in mango especially in cultivar Amrapali under the sub-Himalayan subtropics of India. Materials and Methods: Incidental occurrence of vivipary in mango has been reported from the Hamirpur district of Himachal Pradesh during the growing season of the year 2021. Upon observance of abnormal protuberances from the fruit surface, the harvesting was commenced at the weekly intervals and the per cent proportion of viviparous fruits was ascertained by cutting the fruits longitudinally and confirming the viviparous germination of the seeds. Weather data of the fruit development state were analysed for the accumulation of heat units and rainfall distribution. Efforts have been made for ascertaining the reason behind the viviparous seed development. Results and Discussion: The proportion of viviparous seeds increased with the progression of time and by the mid of September, more than 12% of seeds were found viviparous. The weather data show that there was an early accumulation of heat units. Also, the rainfall during the period of fruit development was high particularly at the time when fruits were advancing toward maturity. It has been observed that the seed maturity has preceded the fruit pulp maturity and ripening may be due to the early accumulation of heat units and high rainfall. This coincidence might have resulted in precocious germination of seed inside the fruit, leading to vivipary. Conclusion: The development of vivipary in Amrapali mango has been found to be associated with the early accumulation of heat units and high rainfall. Under the current changing climatic scenario, a need has been projected for strategic research for curtailing vivipary incidences and saving economic losses to the growers of late mango varieties in the sub-Himalayan subtropics.

Rice is a water-loving crop and traditionally sown in the nursery and then transplanted to the puddled and waterlogged main field. Owing to climate change, water scarcity and labour shortage problems, rice is now cultivated in the dry direct seeded method. Owing to potential of hybrid rice in increasing both rice production and productivity, many countries are focusing on exploiting the benefits of this technology. To break the yield plateau in rice cultivation, Thermosensitive Genetic Male Sterile (TGMS) hybrids were found to be very effective. In the present study, 41 TGMS hybrids and 9 checks were evaluated for their stability and adaptability by dry direct seeded method in four locations viz., E1 - Allahabad, E2 - Lucknow, E3 - Dhamtari and E4 - Raipur. The TGMS hybrid G44 was predicted as an ideal hybrid by the GGE stability model that possessed high grain yield and stable performance over environments. It was followed by hybrids viz., G10, G14, G34, G11, G20 and G47 that had a stable performance with high yield. Hence, these TGMS hybrids were identified as high and stable yielders across environments and suitable for dry direct seeded rice ecosystems. Among the environments, E1 (Allahabad) and E4 (Raipur) were considered favourable environments as they possessed the highest discriminating power. The hybrids identified in the study can be utilized for breaking the yield barriers in rice and can be recommended for dry direct seeding in marginal and rainfed areas.

Root rot of mung bean [Vigna radiata (L.) Wilczek var. radiata] is major disease and claims huge yield loss if they occur in the field. The pathogen is basically soil borne and survivability may vary depends on soil condition. The fungicide chemicals are available to manage the disease; however, the biocontrol agents are nowadays available for the disease management and the microbial activity of the biocontrol agents is influenced by existing soil condition including soil pH. Hence, a study was conducted to find out the halo tolerance capacity of the biocontrol agents against root rot disease in salt affected soils under in vitro, in vivo and field condition. The root rot pathogen Macrophomina phaseolina was isolated from infected root. Efficacy of biocontrol agents against growth of M. phaseolina was assessed in vitro. The results revealed that TNAU strain of Bacillus subtilis reduced the mycelial growth of the M. phaseolina significantly when media supplemented with NaCl at 5% (1.4 cm), 7.5% (1.5 cm), 10% (1.6cm) and 12.5% (1.6 cm) and without NaCl (1.2 cm) and similar trend of reduction also expressed by BCA1 strain of B. subtilis, Pseudomonas fluorescens and Trichoderma viride under in vitro. The performance of the biocontrol agents against the pathogen is slightly reduced when media supplemented with NaCl. The reduction of mycelia weight of M.phaeolina was more in media added with TNAU strain of B.subtilis and the performance of TNAU strain of B.subtilis on reduction of mycelial weight of M.phaseolina is reduced when the broth added with NaCl at 5% (3.15g), 7.5% (3.25g), 10% (3.32g) and 12.5%(3.65g) level and which is followed by P. fluorescens, BCA 1 strain of B. subtilis and Trichoderma viride. Under pot culture conditions, the effect of talc formulated biocontrol agents and challenge inoculation with pathogen was assessed against root rot incidence. It was found that the soil application of TNAU strain of B.subtilis performed better in reducing the root rot incidence at pH of 7.0 (2.37%), 7.5 (4.50%), 8.0 (5.53%) and 8.7 (6.57%) and followed by BCA 1 of B.subtilis in all pH level. Among the biocontrol agents, TNAU strain of B.subtilis applied as seed as well as soil application expressed more population in the rhizosphere in all pH level. The biocontrol agents applied as soil application had more populations of the agents in the soil when compared to seed treatment. The halo tolerance performance of the biocontrol agents was also assessed under field condition in pH of 7.5 and 8.7 during 2019-20 and 2020-21. It was found that the minimum root rot incidence and maximum yield was observed from soil application of TNAU strain of B subtilis at 2.5 kg/ha but the effect is on par with soil application of BCA1 strain of B.subtilis at 2.5 kg/ha.

A field experiment was conducted during spring 2020-21 at Wetland farms of Tamil Nadu Agricultural University, Coimbatore to study the effect of foliar Nanonutrients (N, Zn and Cu) application on the yield and nutrient uptake by rice at harvest. Twelve treatments with three replications were laid out in randomized complete block design. The results revealed that application of 100% NPK + Nano N at active tillering (T3) and 75% N + 100% PK + Nano N at active tillering (T4) increased the grain yield (5112 and 5063 kg ha-1) and N uptake (106.48 and 89.51 kg ha-1) of rice, respectively and was on par with 100% NPK + Nano Zn at active tillering and panicle emergence (T10). However, significantly higher Zn and Cu uptake were recorded in 100% NPK + Nano Zn at active tillering and panicle emergence (T10, 457.61 g ha-1) and 100% NPK + Nano Cu at active tillering and panicle emergence (T12, 92.36 g ha-1), respectively which was followed by 100% NPK + Nano N at active tillering (T3, 372.45 and 81.51 g ha-1) and 75% N + 100% PK + Nano N at active tillering (T4, 355.41 and 84.13 g ha-1). Thus, it can be concluded that application of foliar Nano N at active tillering along with soil application of either 100% NPK or 75% N + 100% PK can provide better results in terms of grain yield and nutrient uptake.

Knowledge about the association between grain yield and yield contributing traits is important for sorghum development programs. Thus, the aim of this study was to determine correlations and path-coefficients between grain yield per plant and yield contributing traits. The experiment was conducted during Kharif 2019 in the Department of millets, TNAU, Coimbatore, India by using nine parents and twenty hybrids to study the genotypic correlations on the basis of seventeen traits. Analysis of variance evinced significant variation for all the traits under study. In correlation studies, the grain yield was positively associated with plant height (0.603), leaf length (0.613), leaf area index (0.501), flag leaf length (0.529), panicle length (0.608), panicle weight (0.930) and hundred seed weight (0.643). In path analysis, the traits leaf length, flag leaf length, panicle length, panicle weight and hundred seed weight exposed highly direct and indirect effects. Selection for a trait is effective when both the correlation and direct effect are higher and positive as this indicates its true association. Hence this investigation revealed flag leaf length, panicle length, panicle weight and hundred seed weight exhibited positive association and direct effect on grain yield, which indicates that the selection towards these characters will improve the yield.

In correlation studies, the grain yield was positively associated with plant height (0.603), leaf length (0.613), leaf area index (0.501), flag leaf length (0.529), panicle length (0.608), panicle weight (0.930) and hundred seed weight (0.643). In path analysis, the traits leaf length, flag leaf length, panicle length, panicle weight and hundred seed weight exposed highly direct and indirect effects. Selection for a trait is effective when both the correlation and direct effect are higher and positive as this indicates its true association. Hence this investigation revealed flag leaf length, panicle length, panicle weight and hundred seed weight exhibited positive association and direct effect on grain yield, which indicates that the selection towards these characters will improve the yield.","PeriodicalId":14335,"journal":{"name":"International Journal of Plant & Soil Science","volume":"6 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-12-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"74753732","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}

Micronutrients, particularly Iron (Fe) and Zinc (Zn), play a vital role in the growth and development of plants due to their catalytic effect on many metabolic processes. However, the biochemical responses to the applied micronutrients vary with cultivars and their species. A screening experiment was conducted during 2020 to know the antioxidants enzyme activities and biochemical constituents in response to iron and zinc fertilization by six capsicum hybrids grown in grow bags under shade net conditions. The experiment consists of three treatments viz., Control (No Fe & Zn), 50 kg FeSO4 and 37.5 kg ZnSO4 ha-1 as a basal soil application with six capsicum hybrids viz., Indra, Priyanka, Inspiration, Massilia, Bachata, and Local green. Leaf samples of the capsicum hybrids were collected at Fruiting stage and analysed for antioxidant enzyme activities. The fruit samples were used for quantifying the biochemical constituents. The results revealed that, application of ferrous sulphate (FeSO4) and zinc sulphate (ZnSO4) to capsicum hybrids increased the biochemical constituents in fruits and the antioxidant enzyme activities in leaves. Out of the six hybrids tested, Indra possessed higher ascorbic acid content (9.20 mg 100 g-1 fresh weight), acidity (6.0), and total soluble solids (6.10 Brix) in the fruits, which was followed by Inspiration and Bachata. The superoxide dismutase (6.70 unit’s mg-1 protein) and peroxidase (6.90 unit’s g-1 fresh weight) activities were also higher with the same genotypes. The biochemical constituents and antioxidant enzyme response to Zn addition was better than Fe. There was 13.2, 10.9 and 9.5 per cent increase in titratable acidity, total soluble solids, ascorbic acid content in the fruits of Indra due to ZnSO4 application.The Principal Component Analysis (PCA) and hierarchical clustering revealed that Indra is highly responsive to Zn and Fe fertilization, while the local green showed very less response. The rest of the genotypes such as Inspiration, Bachata, Massilia, and Priyanka, are medium responsive for Zn and Fe fertilization.
微量元素，特别是铁(Fe)和锌(Zn)，由于它们对许多代谢过程的催化作用，在植物的生长发育中起着至关重要的作用。然而，不同品种和品种对施用微量营养素的生化反应不同。本试验于2020年进行筛选，以6个辣椒杂交种为材料，在遮荫网条件下进行袋养，研究其抗氧化酶活性和生化成分对铁锌施肥的响应。试验包括三个处理，即对照(不含铁和锌)，50 kg FeSO4和37.5 kg ZnSO4 ha-1作为基础土壤施用，6个辣椒杂交种分别是Indra, Priyanka, Inspiration, masilia, Bachata和Local green。在结果期采集辣椒杂交种叶片样品，分析其抗氧化酶活性。用水果样品定量测定其生化成分。结果表明，施用硫酸铁(FeSO4)和硫酸锌(ZnSO4)可提高辣椒杂种果实生化成分和叶片抗氧化酶活性。在测试的6个杂交品种中，因陀罗的抗坏血酸含量(9.20 mg 100 g-1鲜重)、酸度(6.0)和可溶性固体总量(6.10 Brix)较高，其次是灵感和巴查塔。相同基因型的超氧化物歧化酶(6.70单位mg-1蛋白)和过氧化物酶(6.90单位g-1鲜重)活性也较高。对添加锌的生化成分和抗氧化酶的响应优于添加铁。施用ZnSO4后，因特罗果实的可滴定酸度、总可溶性固形物和抗坏血酸含量分别增加了13.2、10.9%和9.5%。主成分分析(PCA)和层次聚类分析表明，因特罗对Zn和Fe的处理响应显著，而局部绿对Zn和Fe的处理响应较弱。其余基因型如Inspiration、Bachata、Massilia和Priyanka对锌和铁的施肥反应中等。

Agriculture has been indispensable for the subsistence of the people of India in general and farmers in particular. It has naturally been the cornerstone of the Indian economy since time immemorial and agriculture has played a major role in the country's economy since its inception. The research work was done to study the effect of irrigation levels on the yield and growth of winter marigolds. Marigold (Tagetes erecta L.) had been taken twice the winter season of 2019-20 and 2020-21. The average flower yield (t/ha) was recorded under the treatment I1 (12.03 t/ha) was found maximum and it was followed by I2 (10.51 t/ha), I3 (9.73 t/ha). The consumptive water use (CWU) was found maximum (26.62 cm) in 100% of ETc and the lowest CWU was found (21.03 cm) in 80% of ETc through a drip system of irrigation in the cropping year 2020-21. Similarly, in 2019-20 CWU was found maximum (18.02 cm) in 100% of ETc, while the lowest CWU was found (14.42 cm) in 80% of ETc. The water use efficiency was found highest in I3 (0.77 t/ha/cm) and minimum WUE was found in I2 (0.525 t/ha/cm) in the cropping year 2019-20. For 2020-21, a maximum WUE was recorded in I2 (0.497 t/ha/cm) and the minimum WUE in I3 (0.335 t/ha/cm).
