A study was under taken during kharif season of 2016 at College of Agriculture, Bheemarayanagudi and UAS, GKVK, Bengaluru to estimate the combining ability and investigate gene action involved in inheritance of yield and its components traits of maize inbreds through 20×20 full diallel cross analysis. 380 SCHs synthesized through full diallel mating design were evaluated in simple lattice square lattice design at two locations. Analysis of variance revealed significant differences among the hybrids, parents vs. hybrids and straight crosses for all the characters and among the parents for all the characters except ASI, ear circumference and shelling %. Significant differences were also recorded in reciprocal crosses for all the characters except ear circumference and shelling %. Significant GCA variance for grain yield revealed the role of additive components of genetic variance. SCA variance was also highly significant for all characters except ear circumference and test weight indicating the importance of both additive and non additive components of genetic variance. However, there was predominance of additive gene action recorded for all the characters. GCA: SCA variance ratio was less than unity for all the traits, suggesting the predominance of non-additive gene action. Inbreds MAI 283 and VL 109252 were identified as good general combiners as they registered significant gca effects in positive direction for grain yield and its component traits. Straight cross MAI-283×KDMI-16 and reciprocal cross M 04×KDMI 16 registered highest significant sca effects in positive direction for grain yield along with high and significant sca effects in negative direction for ASI.

The investigations were carried out to evaluate the 64 genotypes (28 F1, 28 F2 and 8 parental lines) of pumpkin ((Cucurbita moschata Duch. Ex Poir.)’at Department of Vegetable Science, Kalyanpur, CSA. University of Agriculture and Technology, Kanpur (U.P.) during Zaid 2021. The experiments were laid out in randomized complete block design with three replications. The data were recorded for 19 characters including total fruit yield per plant and its component traits. Analysis of variance showed that there was highly significant variation for all the characters studied. In F1 generation, the highest genotypic as well as phenotypic coefficients of variations were observed for fruit yield/plant. In F2 generation, the highest genotypic as well as phenotypic coefficients of variation were observed for fruit yield/plant and average fruit weight. In F1, high heritability in narrow sense coupled with high genetic advance as per cent of mean were observed for equatorial circumference of fruit, polar circumference of fruit and seeds/fruit while in F2, high heritability coupled with high genetic advance as percent of mean were observed for seeds/fruit. High estimate of heritability along with high genetic advance in percent of mean provides good scope for further improvement in advance generations.

A field experiment was conducted to evaluate the effect of different organic sources of nutrientson growth physiology and yield components of scented rice, variety KetekiJoha at Regional Agricultural Research Station, AAU, Titabor during 2017 and 2018. Eight treatments were evaluated in randomized block design with three replications. The results revealed that the application of different proportion of organic sources of nutrients significantly improved the growth physiology and yield parameters of scented rice over the control. Among the treatments,the application of green manure (2.5 t ha-1) + Vermicompost (2.5 t ha-1) + Azolla (20 kg ha-1) + biofertilizer consortium (4 kg ha-1 seedling) as root dip + rock phosphate (17 kg ha-1) recorded the highest grain yield (38.05 qha-1) with significant increase in yield components of the crop.Application of green manure + Vermicompost + Azolla + biofertilizer consortium as root dip + rock phosphate significantly produced higher plant height (78.5cm), leaf area index (4.3), flag leaf area (35.3cm-2), total Chlorophyll content (3.5mgg-1fwt), panicles m-2 (304.3), panicle length (28.2 cm), grains panicle-1(108.4),panicle weight (2.7 g), harvest index (35.2 %) and 1000 grain weight(23.6 g). The organic treatments also significantly enhanced the growth physiology viz., crop growth rate, specific leaf weight and net assimilation rate of the plant.

Secondary soil salinization is a major issue for sustaining food grain production in arid and semi-arid region due to the use of poor quality saline water, whichneeds amelioration before to be used for crop irrigation.In this regard, totally 12 saline bacterial isolates from saline water ecosystem, of which three best isolates, namely C8, C10 and C12, identified and used for amelioration of saline water whose electrical conductivity value (EC) ranged between 0.5 and 8.0 dS m-1 over the incubation period of two, five and seven days under laboratory conditions during 2017-20. The C10 and C12 bacterial isolates were highly efficient recording more than 30 % EC value decline but microbial efficiency decreased with increased salt concentration. The five days incubation optimized with 20 % reduction of EC value. However, the biological amelioration of water salinity was highly specific that five days incubation with C12 culture recording amelioration nearly 64 % decline of EC value only in low saline water. In contrast, all the cultures were equally effective on every saline water studied lowering more than 38% in 2.0 dS m-1 saline water, more than 22 % in 4.0 dS m-1 saline water, more than 16 % in 6.0 dS m-1 saline water, and more than 12 % in 8.0 dS m-1saline water for two days incubation period. On the whole, the microbial techniques based saline water amelioration abated 30% reduction of EC value associated with declining of ionic concentrations, such as Ca2+ by 40 %, Mg2+ by 31 %, Na+ by 24 %, SO42- by 18.4 % and Cl- by 10.5 %. The reduced salt build-up and increased crop performance would be the implication and characterization of the isolates is suggested further studies.

The field experiment was conducted during 2017-18 and 2018-19 at Oilseeds Research Unit, Dr. Panjabrao Deshmukh Krishi Vidyapeeth, Akola (Maharashtra) to study the effect of fertilizer and soil amendment on soil fertility and yield groundnut (Arachis hypogaea L.). The experiment was laid out in randomized block design with three replications and nine treatments. The pooled data revealed that the application of gypsum and phosphogypsum did not influence significantly the soil pH, EC, organic carbon and calcium carbonate content. However, the fertility status of soil in terms of available nitrogen, phosphorus, potassium and sulfur as well as exchangeable calcium, magnesium was found significantly higher with the application of RDF-sulfur free + 400 kg phosphogypsum ha-1. The available nitrogen, phosphorus, potassium, sulfur, exchangeable calcium and magnesium contents were increased by 10, 23, 7, 122, 42, and 14% with RDF-sulphur free + 400 kg phosphogypsum ha-1 as compared to control, respectively. Significantly higher pod (2.0 t ha-1) and haulm yield (2.5 t ha-1) of groundnut was observed with RDF-sulphur free + 400 kg phosphogypsum ha-1. Similarly, the oil and protein contents were also increased with phosphogypsum level and maximum oil (51%) and protein (29.4%) contents were observed with RDF-sulphur free + 400 kg phosphogypsum ha-1 treatment. This treatment was statistically at par in terms of soil fertility, yield, oil and protein content of groundnut with RDF-sulphur free + 300 kg phosphogypsum ha-1.

However, the fertility status of soil in terms of available nitrogen, phosphorus, potassium and sulfur as well as exchangeable calcium, magnesium was found significantly higher with the application of RDF-sulfur free + 400 kg phosphogypsum ha-1. The available nitrogen, phosphorus, potassium, sulfur, exchangeable calcium and magnesium contents were increased by 10, 23, 7, 122, 42, and 14% with RDF-sulphur free + 400 kg phosphogypsum ha-1 as compared to control, respectively. Significantly higher pod (2.0 t ha-1) and haulm yield (2.5 t ha-1) of groundnut was observed with RDF-sulphur free + 400 kg phosphogypsum ha-1. Similarly, the oil and protein contents were also increased with phosphogypsum level and maximum oil (51%) and protein (29.4%) contents were observed with RDF-sulphur free + 400 kg phosphogypsum ha-1 treatment. This treatment was statistically at par in terms of soil fertility, yield, oil and protein content of groundnut with RDF-sulphur free + 300 kg phosphogypsum ha-1.","PeriodicalId":8031,"journal":{"name":"Annals of Plant and Soil Research","volume":"8 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"85958199","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}

The study was carried out during 2015-16 at district Sriganganagar under semi arid region of Rajasthan India with the aim to diagnose the soil fertility indicator by using DRIS norms to improve the kinnow orchards efficiency. A total 105 kinnow mandarin orchards were selected through the preliminary survey, all the selected orchards were divided equally 35 each in low, medium and high efficiency based on the yield. The soil and plant sample were collected from the orchards and subjected to analyze by using standard analysis protocols. Five tier DRIS norms were used for determining the soil properties limiting factor. The high efficient orchards had low pH (8.1) and CaCO3, (23.4 g kg-1) whereas, comparatively more organic carbon (2.7 g kg-1) , phosphorus (38.2 kg ha-1) and potassium (296.2 kg ha-1) than medium and low efficient orchards. The nitrogen, phosphorus and potassium contents were also high in high yield orchards and ultimately responsible for the better quality parameters viz. fruit weight (170.35 g), Juice (49.51 %), total soluble sugar (12.88 %) and low acidity (0.81 %) in high efficient orchards. The five tier DRIS norms suggested that < 8.8 pH, < 89.0 g kg-1 CaCO3, < 2.5 g kg-1 organic carbon and 14.2 kg ha-1 phosphorus were limiting soil fertility indicators in relation to fruit yield less than 14.5 t ha-1 for kinnow mandarin orchards of semi arid region of Rajasthan. It is evident from the DRIS norms in relation to soil properties and plant tissue concentration yield should be considered as low when it is less than 14.5 to 20.2 t ha-1. It is therefore imperative to manage these parameters for the better quality production and sustainability of kinnow orchards
该研究于2015-16年在印度拉贾斯坦邦半干旱地区的Sriganganagar区进行，目的是利用DRIS规范诊断土壤肥力指标，以提高kinnow果园的效率。通过初步调查，共选择了105个金瓯柑果园，根据产量将果园按低、中、高效率平均分为35个果园。从果园采集土壤和植物样本，采用标准分析方案进行分析。采用五层DRIS规范确定土壤性质限制因子。高效果园的pH值(8.1)和CaCO3 (23.4 g kg-1)较低，有机碳(2.7 g kg-1)、磷(38.2 kg ha-1)和钾(296.2 kg ha-1)高于中、低效果园。高产果园的氮、磷、钾含量也较高，最终导致了高产果园较好的品质参数，即果重(170.35 g)、果汁(49.51%)、总可溶性糖(12.88%)和低酸度(0.81%)。5级DRIS指标表明，在拉贾斯坦半干旱区，pH < 8.8、CaCO3 < 89.0 g kg-1、有机碳< 2.5 g kg-1、磷< 14.2 kg ha-1是制约柑桔园果实产量小于14.5 t ha-1的土壤肥力指标。从与土壤性质和植物组织浓度相关的DRIS规范中可以明显看出，当产量低于14.5至20.2 t hm -1时，应被视为低产量。因此，必须对这些参数进行管理，以提高kinnow果园的质量和可持续性

An experiment was conducted during 2019 and 2020 at College of Agriculture, Sumerpur (Rajasthan) to study the effect of organic weed management and organic nutrient management treatments practices on maize (Zea mays L.)in split plot design with 3 replications.The two years mean data revealed that the minimum weed infestation (79.1%) and maximum weed control efficiency (93.1%) was recorded in weed free check as against weedy check among various weed management treatments at harvest. Most of the growth attributes, grain (3.36 t ha-1) and stover (6.26 t ha-1) yield of maize were significantly affected by weed management and nutrient management practices and found maximum in weed free check maintained up to 60 DAS closely followed by stale seedbed+ hoeing once at 20 DAS + straw mulch applied @ 5 t ha-1 at 30 DAS against weedy check. The application of vermicompost @ 75% of recommended dose of nitrogen (RDN i.e. 90 kg N equivalent) in two splits (75% at sowing +25% as top dressing at 30 DAS) along with seed treatment with fermented beejamurt and two sprays of jeevamurt registered significantly hgher growth parameters besides grain yield of 3.17 t ha-1as compared to 100% RDN through FYM. The mean gross return, net return and B:C ratio were significantly affected by various weed and nutrient management practice and maximum values were recorded with weedy check and 755% RDN through vermicompost + STB + JT, respectively.
本试验于2019 - 2020年在拉贾斯坦邦Sumerpur农业学院进行，采用3个重复的分畦设计，研究有机杂草管理和有机养分管理对玉米(Zea mays L.)的影响。2年平均数据显示，收获期各种杂草管理措施中，无杂草检查与杂草检查的杂草侵害率最低(79.1%)，杂草防治效率最高(93.1%)。杂草管理和养分管理对玉米的大部分生长属性、籽粒产量(3.36 t ha-1)和秸秆产量(6.26 t ha-1)均有显著影响，在无杂草检查中，最大产量维持在60 DAS，其次是旧苗床+ 20 DAS锄一次地+ 30 DAS覆盖5 t ha-1秸秆。蚯蚓堆肥施氮量为推荐量的75% (RDN即90 kg N当量)，分两次施用(播种时75% + 30 DAS追肥时25%)，同时用发酵蜂粕和两次喷施jeevamurt进行种子处理，与100% RDN相比，在FYM期间，除籽粒产量为3.17 t ha-1as外，生长参数显著提高。不同杂草和养分管理方式对平均毛收益、净收益和B:C比均有显著影响，杂草检查和蚯蚓堆肥+ STB + JT + 755% RDN分别达到最大值。
