Background: The successful growth and development of the vanilla plant are supported by the availability of soil nutrients that are absorbed by the plant roots. Natural fertilizers derived from plant waste easily decompose in the soil so that they are more quickly absorbed by roots and stored in plant cells. The purpose of this study was to determine the effect of eco-enzymes and husk charcoal on the growth of vanilla seedlings. Methods: This study was designed using a complete randomized block design. The first factor was eco-enzyme (without eco-enzyme and with eco-enzyme 15 ml/plant), namely E0 and E1, the second factor was the husk charcoal dose (0, 5, 10, 15) g/plant, P0, P1, P2, P3. Data were analyzed using ANOVA analysis of variance with Duncan’s multiple range test (DMRT) with a significant difference of 5%. The results showed that the best vanilla growth was obtained by treating it with 15 ml/polybag eco-enzyme and 15 g/polybag coconut shell charcoal (E1P3). Result: The plant height reaches 79.67 cm, the number of leaves reaches 12.67 strands and the width reaches 405.42 mm. The fresh weight of the plants reached 71.33 g, the dry weight of the plants reached 28 g, the fresh weight of the roots reached 8.6 g, and the dry weight of the roots reached 1.27 g. Microscopi observation showed that eco enzymes and coconut shell charcoal infected the roots and filled the tissues, then played a role in increasing the growth of the vanilla seedlings.

Background: Productivity, as a source of growth has been a significant premise of analytical investigation in economics all along, however it gained an empirical momentum in the recent years only and has become a necessary index to growth. Present paper estimates growth rate of area, production and productivity of food grain and oilseed crops in Rajasthan. Methods: To analyse growth performance of food grain and oilseed crops Rajasthan time series, data on area, production and yield were collected from 1976-77 to 2018-19. The time-series data were collected on area, production and yield of selected crops from the Directorate of Economics and Statistics (DES), Directorate of Agriculture (DOA) and Rajasthan State Agriculture Department. The compound growth rates (CGRs) of area, production and productivity of selected crops in Rajasthan were calculated using the exponential function. Result: The study revealed that production, productivity and area of total food grains was recorded a positive and highly significant annual growth at the rate of 3.18%, 2.19% 0.63% per annum, respectively. The production, productivity and area of total oilseed was observed a positive and highly significant annual growth rate of 7.63%, 2.07% and 4.27% per annum, respectively. The area under barley, gram and sesamum reduced during the study period. Therefore, the technological support through the varietal improvement and extension support is required.

Background: The low amount of rainfall and high loss of soil water through evaporation during spring; there are the dominant factors affecting crop production in semi-arid region. Methods: A field study was conducted during two cropping seasons of durum wheat (Triticum durum Desf.) to compare the effect three tillage operations viz., no-tillage, minimum tillage and conventional tillage. Result: There was variation in precipitation between the experimental years (dry and rainfall seasons). All the parameters registered significant differences between the cropping seasons. Soil water storage to a depth of 0.4 m was higher under no tillage (NT) and minimum tillage (MT) in the first year as compared to conventional tillage (CT) in the first year. During the second year, the soil water content was same under different tillages. The thousand-kernel weight registered significant differences among the tillage operations viz., no till (36.09-50.36 g), minimum tillage (30.93-46.81 g) and conventional tillage (28.31-45.05 g) in the two seasons, respectively. Under no till treatment water use efficiency was high from grain production. The no till also recorded high grain yield of 1.07 t/ha and 4.7 t/ha during first and second year, respectively. The lack of rain was more detrimental in conventional tillage system as compared to no till and minimum tillage.

Background: Cereal-legume cropping system is considered to be one of the better alternatives for sustaining soil fertility and increasing the yield. At present maize-groundnut cropping system is gaining importance under both rainfed and irrigated situations. Maize, being an exhaustive and weed-sensitive crop, is supplied with large doses of fertilizers and new herbicide molecules.Since maize is exhaustive and weed sensitive crop, there was a usage of excessive fertilizers and new herbicides. There is a need to assess the carry over effect of fertilizers and new generation herbicides in leguminous crops like groundnut. Methods: The experiment was conducted during two consecutive rabi seasons of 2019-20 and 2020-21 on sandy loam soils of S.V. Agricultural College, Tirupati andhra Pradesh. Maize hybrid DHM -117 was sown and maintained with general cultivation practices except for nitrogen and weed management methods was raised after harvest of maize in undisturbed layout to study the residual effect of different nitrogen and weed management practices imposed in maize. Result: Residual effect of nitrogen and weed management practices imposed in preceding maize did not exert any significant influence on germination percentage, phytotoxicity and SPAD chlorophyll meter reading (SCMR) values but efficacy of herbicide residue found to be significant with weed management practices. Growth parameters, yield attributes pod yield, haulm yield and economics were higher in groundnut with brown manuring, which was however, in parity with hand weeding twice at 15 and 30 DAS, pre emergence application of atrazine 1.0 kg ha-1 fb post emergence application of topramezone 30 g ha-1 and pre emergence application of atrazine 1.0 kg ha-1 fb post emergence application of tembotrione 120 g ha-1 and lower with unweeded check and it was remained in parity with application of parthenium water extract15 lha-1 twice at 15 and 30 DAS, application of sunflower water extract 15 lha-1 twice at 15 and 30 DAS, pre emergence application of atrazine 1.0 kg ha-1 fb post emergence application of parthenium water extract 15 lha-1 and pre emergence application of atrazine 1.0 kg ha-1 fb post emergence application of sunflower water extract 15 lha-1 in the order of ascent. None of their interaction effects were found to be significant during both the years of study and in pooled mean.
背景：谷物-豆类种植系统被认为是维持土壤肥力和提高产量的最佳选择之一。目前，玉米-花生种植系统在雨水灌溉和灌溉条件下都越来越重要。玉米是一种耗竭性作物，对杂草敏感，因此需要使用大剂量化肥和新型除草剂分子。有必要评估化肥和新一代除草剂对落花生等豆科作物的累积效应。方法：实验于 2019-20 年和 2020-21 年连续两季在提鲁帕提邦 S.V. 农业学院的沙质壤土上进行。播种玉米杂交种 DHM -117 并采用除氮肥和杂草管理方法外的一般栽培方法，在玉米收获后在不受干扰的布局中种植，以研究不同氮肥和杂草管理方法对玉米的残留影响。结果玉米收获前施用氮肥和杂草管理方法的残留效应对发芽率、植物毒性和 SPAD 叶绿素读数（SCMR）值没有显著影响，但发现除草剂残留的效力与杂草管理方法有显著关系。使用褐肥的花生的生长参数、产量属性、豆荚产量、茎秆产量和经济效益都较高，但与在 15 和 30 DAS 两次人工除草、出苗前施用阿特拉津 1.0 kg ha-1 和出苗后施用托布津 30 g ha-1、出苗前施用阿特拉津 1.0 kg ha-1 和出苗后施用托布津 30 g ha-1、出苗前施用阿特拉津 1.0 kg ha-1 和出苗后施用托布津 30 g ha-1 的效果相当。0 kg ha-1 fb出苗后施用 tembotrione 120 g ha-1，低于未除草对照，与在 15 和 30 DAS 两次施用 parthenium 水提取物 15 lha-1、在 15 和 30 DAS 两次施用向日葵水提取物 15 lha-1、出苗前施用阿特拉津 1.出苗前施用阿特拉津 1.0 kg ha-1 和出苗后施用向日葵水提取物 15 lha-1。在研究的两个年份中，它们之间的交互作用均不显著。

Background: Cotton (Gossypium hirsutum L.) is crop of economic importance in global and national scale. India is the greatest producer of quality cotton, the third largest exporter and the second largest consumer. Conventional cotton farming creates environmental pressures and negative impact on public health. Organic farming is the sustainability option in cotton production. Cotton is the energy intensive crop, which uses high amount of input energy to produce seed cotton. Hence, energy budgeting is highly essential for better energy utilization and resource conservation and also measuring the input use efficiency of a farm/agronomic practices is vitally important in present day Indian agriculture. Methods: Sensing the economic importance of cotton, ten number of eco-friendly, ecologically safe organic nutrient management (ONM) practices were framed and field experiment was conducted in split plot design with two main plots (M) and five subplots (S) and replicated thrice. The direct and indirect energy used in different ONM practices were computed and energy coefficients were computed from energy equivalents and that has been used as inputs to generate efficiency coefficients by using an input oriented DEA approach. Result: Energy budgeting on field operation basis reported that, the field preparation and irrigation operation uses most of the energy (in non-renewable forms) which needs attention and there is the scope to find alternative energy conservation systems. Results on input use efficiency reported that the ONM practice, double green manuring followed by cotton and application of well decomposed poultry manure and foliar application of fermented fish extract at 5% concentration at 25 and 35 DAS are 100% efficient in terms of technical CRS, technical VRS, scale, allocative and cost efficiencies. This organic nutrient management practice would produce optimum output from the least amount of input and would be ideal for sustainable cotton production.
背景：棉花（Gossypium hirsutum L：棉花（Gossypium hirsutum L.）是在全球和国家范围内具有重要经济意义的作物。印度是最大的优质棉生产国、第三大出口国和第二大消费国。传统的棉花种植会对环境造成压力，并对公众健康产生负面影响。有机种植是棉花生产的可持续性选择。棉花是能源密集型作物，生产籽棉需要消耗大量能源。因此，编制能源预算对于更好地利用能源和保护资源非常重要，同时，衡量农场/农艺实践的投入使用效率对于当今的印度农业也至关重要。方法：考虑到棉花的经济重要性，制定了十种生态友好、生态安全的有机养分管理（ONM）方法，并采用两个主小区（M）和五个子小区（S）的分小区设计进行田间试验，重复三次。通过使用以投入为导向的 DEA 方法，计算了不同有机养分管理方法中使用的直接和间接能源，并根据能源当量计算了能源系数，以此作为生成效率系数的投入。结果：对田间作业进行的能源预算显示，田间准备和灌溉作业使用了大部分能源（不可再生形式），需要引起重视，并有可能找到替代性节能系统。关于投入品使用效率的研究结果表明，有机养分管理方法，即在棉花和施用充分腐熟的家禽粪肥后进行双重绿肥，以及在 25 和 35 DAS 期叶面喷施浓度为 5%的发酵鱼提取物，在技术 CRS、技术 VRS、规模效率、分配效率和成本效率方面均达到 100%的效率。这种有机养分管理方法能以最少的投入产生最佳的产出，是棉花可持续生产的理想选择。

This organic nutrient management practice would produce optimum output from the least amount of input and would be ideal for sustainable cotton production.","PeriodicalId":13398,"journal":{"name":"Indian Journal Of Agricultural Research","volume":"17 2","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-04-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140714778","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}
Background: Crop establishment methods and nutrient management practices treatments were continuously practiced in the same plots since 2011-12 as a part of long-term experiment. A field study was conducted during 2019-2020 and 2020-2021 i.e. during 9th and 10th year of study to investigate the effects of CE methods and nutrient management on growth, physiological, biochemical, yield attributes and yield of rice crop. Methods: Field experiments were carried out at the Agricultural Research Farm, Banaras Hindu University, Varanasi, laid out in split plot design replicated thrice with four crop establishment (CE) methods viz., CT (puddled transplanted) rice-CT wheat (CE1),CTDSR rice-CT wheat (CE2), CTDSR- ZT wheat (rice residue retention) (CE3), ZT rice-ZT wheat (residue retention in rice and wheat) (CE4) in main plots and three nutrient management (NM) practices viz., FP (164 kg N, 50 kg P2O5, 32 kg K2O and 4 kg Zn ha-1) (N1), RFD (150 kg N, 60 kg P2O5, 60 kg K2O and 5 kg Zn ha-1) (N2) and SSNM- RWCM recommendation (N3). The rice variety used was ‘Sarju-52’ in the present study. Result: The recorded data revealed that ZT rice–ZT wheat (CE4) recorded significantly higher plant height, tillers hill-1, leaf area, RWC, total chlorophyll content and protein content as compared to other CE methods. Among NM practices, SSNM-RWCM (N3) recorded significantly higher plant height, tillers hill-1, leaf area and protein content, whereas, RWC and total chlorophyll content did not differ significantly over farmer’s practice and recommended fertilizer dose. Improved growth and physio-chemical attributes in ZT rice-ZT wheat (CE4) and SSNM-RWCM (N3) resulted in significantly higher panicles hill-1, fertility percentage and number of filled grains panicle-1 over other CE methods and NM practices. Panicle length, spikelets panicle-1 and test weight showed non-significant differences. Grain yield, straw yield and biological yield were significantly higher in ZT rice-ZT wheat (CE4) among CE methods and SSNM-RWCM (N3) among NM practices. The harvest index showed non-significant differences for CE methods and NM practices both.

Background: Mungbean is an important grain legume crop. It contains a high amount of protein, carbohydrates, vitamins and minerals. The productivity of this crop is still low, hence efforts should be made to improve the yield of mungbean by keeping knowledge about association between seed yield and its components. Thus, the present investigation was aimed to determine the correlation and path coefficient analysis for seed yield and its attributing traits in mungbean. Methods: Seventy-nine diverse genotypes of mungbean were evaluated during Kharif 2017-18 for eleven quantitative traits in randomized block design with three replications at the Experimental farm, Department of Genetics and Plant Breeding, College of Agriculture, Swami Keshwanand Rajasthan Agricultural University, Bikaner, Rajasthan. Result: Significant genotypic differences were observed for all the traits studied indicating a considerable amount of variation among genotypes for all the characters. The seed yield per plant exhibited highly significant and positive correlation with number of pods per plant, biological yield per plant, harvest index, number of seeds per pod and pod length. The characteristics such as biological yield per plant, harvest index, number of pods per plant, pod length, number of seeds per pod, plant height, 100-seed weight and days to 50 per cent flowering had high positive direct effect on seed yield per plant. Therefore, selection based on the traits viz., number of pods per plant, biological yield per plant, harvest index, number of seeds per pod, 100-seed weight and pod length could help in enhancing the seed yield per plant in mungbean.

Background: Cotton, maize and pulses are widely grown crops in the western zone of Tamil Nadu, resulting in a significant accumulation of crop residues throughout the year. The persistence of these crop residues after harvest can cause problems for farmers and the soil system. Therefore, the goal of the current study is to investigate the carbon mineralization process in these residues to enrich the soil’s nutrient content, turning waste into a valuable resource. Methods: The incubation experiment comprised 13 treatments, each with three replicates. These included a control, surface residue addition, buried residue addition and various combinations of soil, residue, microbial consortia, urea and jaggery, both on the soil surface (S) and incorporated into the soil (I). Result: The incorporation of crop residues into the soil, along with the addition of 1% microbial consortia, 2.0% jaggery and 1% urea, significantly enhanced carbon mineralization. Among the three crop residues, cowpea exhibited the highest performance, followed by cotton and maize, with values of 692, 564 and 522 µg C g-1 soil, respectively. This trend was further supported by the Michaelis-Menten model (V = 951.72 * x/22.13 + x), with a high goodness-of-fit represented by an R2 value of 0.95 for cowpea. The maximum Vmax (951.72 µmol/min) further substantiates the efficient carbon mineralization achieved by utilizing allocated resources in cowpea-incorporated crop residues (CWFI).
