Background: Groundnut or peanut (Arachis hypogaea L.) is known as the “King of Oilseeds” which belongs to family Fabaceae (Leguminosae). It is highly susceptible to weed infestation because of its slow initial growth up to 40 DAS and small foliage cover. However, study on use of mechanical weed control methods with different fertility regimes for improving the productivity of groundnut was limited. Therefore, the objective of this study was to find a suitable method for optimising the productivity of groundnut. Methods: A field experiment was conducted at Odisha University of Agriculture and Technology, Bhubaneswar for two consecutive years of 2020 and 2021. The field experiment comprised 16 treatment combinations of four weed management practices and four fertility levels. The weed management practice included W1-Pre-emergence (PE) application of pendimethalin @ 0.75 kg ha-1, W2-Pre-emergence (PE) application of pretilachlor @ 0.5 kg ha-1, W3-Manual weeding (20 and 40 DAS), W4-Twin wheel hoe at 20 DAS followed by (fb) hand weeding at 40 DAS and four fertility levels includes T1-100% RDF (20:40:40) (N: P205: K2O kg ha-1), T2- 75% RDF + 5 tonnes FYM ha-1, T3- 50% RDF + 10 tonnes FYM ha-1, T4- without fertilizer + without FYM. Result: Amongst the weed management practices, use of twin wheel hoe at 20 DAS followed by hand weeding at 40 DAS significantly reduced the weed density, weed dry weight, weed index and recorded the highest weed control efficiency (69.8%). Highest weed index (32.9) was recorded with the application of pretilachlor @ 0.5 kg ha-1 (PE), which was followed by weed index of (28.5) with application of pendimethalin @ 0.75 kg ha-1 (PE). The fertilizer management practice with application of 50% RDF + 10 tonnes FYM ha-1 gave the highest yield and considerably reduced the total weed density, weed dry weight and recorded the maximum weed control efficiency (71.8 % at harvest). We suggest that weed management with twin wheel hoe at 20 DAS followed by hand weeding at 40 DAS along with application of 50% RDF + 10 tonnes FYM ha-1 as the most effective strategy for controlling the weed menace in groundnut with the highest weed control efficiency.

Background: Determination of the most important level of salicylic acid to increase guar yield in drought stress conditions. Methods: In order to study the effect of potassium and salicylic acid on agricultural and physiological traits of guar in different irrigation treatments, a field experiment was conducted during 2020-2021 under the climatic conditions of Jiroft area (Kerman province, Iran) in the farm of research center and agricultural and natural resources education. The experimental treatments include three levels of irrigation (regular irrigation, stress 60 and 80% of the plant’s water requirement) in strip plots, three levels of salicylic acid (no application, 0.1 and 0.5 mM) as foliar spraying and two levels of potassium (no application and use of 100% of the plant’s need for potassium) in horizontal plots. Result: The results showed that drought stress and application of potassium and salicylic acid had a significant effect on all traits. Decreasing the amount of water led to a decrease in the physiological and functional characteristics of guar compared to regular irrigation. But potassium and salicylic acid were able to improve the yield characteristics and yield of guar under stress and non-stress conditions and the use of potassium + 0.5 mM salicylic acid were introduced as the best treatment for both conditions. This treatment at 60% stress led to an increase in plant height (91%), the number of leaves (37%), the number of pods (85%), seed number (70%), seed yield (100%), chlorophyll a (61%), chlorophyll b (59%) and carotenoid (100%) compared to the control treatment.

Background: Temperature stress (heat or cold) is becoming a major area of concern due to climate change affecting crop production worldwide. Chickpea leaves are most sensitive to variation in temperature so any variation in temperature (High or Low) causes substantial losses in yield due to disruption in physiological processes of the plant cell. Therefore to achieve maximum production under current scenario of climate change a better understanding of stress induced responses in leaves of chickpea and interrelationship between seed yield and leaf traits can prove to be useful. Methods: The field trials was conducted with ten genotypes of chickpea for two consecutive years (2017-2019) at Pulses Section, Chaudhary Charan Singh Haryana Agricultural University, Hisar to study various traits of leaf at 50% flowering stage (80-90 DAS). Temperature stress (cold or heat) was given by manipulating the sowing dates that is 15th October (early sown condition in Haryana), 15th November (Normal sown condition in Haryana) and 15th December (late sown condition in Haryana). Data were recorded when temperature was ( less than 5°C for 7 days) in early sown and ( greater than 35°C for 7 days) in late sown crops. Result: Results indicated that early sown crops experienced low temperature stress in the month of December-January while late sown crops showed high temperature stress in the month of March- April. The maximum values of leaf parameters were found in crops sown on 15th Novemberand minimum in15th December sown crops and no significant differences in seed yield was recorded between 15th October and 15th November sowing, however, further delay in sowing to 15th December showed significant reduction in seed yield. Among genotypes maximum leaf parameters and seed yield were observed in H12-64 and H13-01 while minimum were found in H14-04. Seed yield exhibited significant positive correlation with all traits in 15th October and 15th November sowing while non-significant was on 15th December sowing.

Background: This study aimed to evaluate the growth performance, biomass production and nutrient accumulation of three abundant leguminous weeds, namely Crotolaria micans Link., Aeschynomene indica L. and Calopogonium mucunoides Desv., found in Mizoram, India, to assess their potentiality as green manure crops. Methods: The field experiment was conducted using a randomized block design. After 90 days of sowing, the growth performance of the plants and biomass accumulation was assessed. Accumulation of nutrients was estimated by analyzing the nutrient content using standard methods and multiplying it with dry biomass. Result: The result revealed that Crotolaria micans showed higher growth and biomass accumulation. C. micans accumulates higher N, P, K, Zn, Cu and Fe contents in the shoot and root biomass while A. indica accumulates higher Ca in the root biomass. We conclude that Crotolaria micans was the most promising leguminous weed species in terms of growth performance, biomass production and nutrient accumulation and has better potential to be utilized as a green manure crop.

Background: Anthracnose is currently a severe threat to green gram cultivation in India. In vitro bioassay and glasshouse studies were performed to evaluate the effectiveness of different fungicides against Collectotrichum lindemuthianum. Methods: The current investigation was conducted at the Department of Plant Pathology, N.M. College of Agriculture, Navsari Agricultural University, Navsari, Gujarat in 2020-21. The poison food technique assessed the efficacy of systemic, non-systemic and combination fungicides against C. lindemuthianum. The management study was also carried out from the best-performing bioassay treatments and evaluated in the glasshouse. Result: At 500 ppm, carbendazim 50 WP and propiconazole 25 EC inhibited 100% of mycelial growth out of six systemic fungicides tested while in non-systemic fungicides, mancozeb 75 WP and chlorothalonil 75 WP inhibited the test pathogen the most at 2500 ppm. Among the combi-fungicides tested at 500 ppm, carbendazim (12%) + mancozeb (63%) 75 WP and captan 70% + hexaconazole 5% 75 WP inhibited pathogen mycelial growth the most significantly more than the untreated control. In glasshouse studies, the lowest disease index was found in two foliar sprays of carbendazim 50 WP @ 1.0 g/l, propiconazole 25 EC @ 2.0 ml/l and captan 70% + hexaconazole 5% @ 0.6 g/l spaced 15 days apart. On the other hand, seed treatment of carbendazim 12% + mancozeb 63% @ 3.0 g/kg seed and mancozeb 75 WP @ 3.0 g/kg seed had the lowest disease index compared to control.

Background: Nanofertilizers are known to be more effective than other types of fertilizers. The present study aims to determine the biochemical stress parameters and yield values obtained when different nanofertilizer applications and doses were applied at different times in sweet corn. Methods: This study was carried out in Antalya, Turkey during the 2020-2021 corn production season. The effects of different nanofertilizer applications on the yield and quality of the Rain Hazar F1 corn variety were investigated. The present study employed 3 different fertilizer application times (3-leaf stage, 12-leaf stage and corn tasseling season), 4 different nanofertilizers (nano-zinc, nano-molybdenum, nano-boron and nano-iron) and 2 different fertilizer doses (125 ppm and 200 ppm). The study was set up using the split-plot design in randomized blocks with 3 replications. Result: The total phenolic content ranged between 271.90±1.51 and 118.80±12.47 mg GAE/g. The total antioxidant content ranged between 87.22±4.58 and 60.39±2.54%. The ascorbic acid peroxidase activity ranged between 4.54±1.46 and 0.17±0.01 EU/mg protein. The total chlorophyll content ranged between 7.43±1.96 and 1.97±0.09 mg/g. It was found in the present study that nanofertilizers can have a significant effect on the growth and development of corn plants.

The total antioxidant content ranged between 87.22±4.58 and 60.39±2.54%. The ascorbic acid peroxidase activity ranged between 4.54±1.46 and 0.17±0.01 EU/mg protein. The total chlorophyll content ranged between 7.43±1.96 and 1.97±0.09 mg/g. It was found in the present study that nanofertilizers can have a significant effect on the growth and development of corn plants.","PeriodicalId":18181,"journal":{"name":"Legume Research","volume":"29 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-10-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135592277","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}
Background: Groundnut kernels contain 48-50% edible oil, 25-34% protein, 10-20% carbohydrates and are a rich source of vitamins (E, K and B complex). Groundnut is a legume-oilseed crop, its requirement of phosphorus, calcium and sulphur is quite high. Gypsum is commonly used as a source of calcium and sulphur for groundnut all over the world. Keeping all these points in view the present study was undertaken to find out the optimum mineral nutrition of spring groundnut Methods: A field experiment was conducted for 2 years at the Students’ Research Farm, Department of Agronomy, Punjab Agricultural University, Ludhiana during spring season of 2018 and 2019. The experiment was laid out in a split plot design replicated three times with four levels of gypsum (0, 125, 175 and 225 kg ha-1) in combination with two gypsum application stages (Full at sowing and 50% at sowing + 50% at flower initiation stage) in the main plot and three levels of nitrogen and phosphorus (15 kg N ha-1 + 20 kg P2O5 ha-1, 25 kg N ha-1 + 30 kg P2O5 ha-1 and 35 kg N ha-1 + 40 kg P2O5 ha-1) in the sub-plot. Result: Application of 225 kg ha-1 gypsum resulted significantly higher growth parameters, pod yield, haulm yield, kernel yield over other gypsum levels. Growth parameters, pod yield, haulm yield and kernel yield were significantly higher with the split application as compared to basal application of gypsum. Growth parameters viz., emergence count, plant height, number of branches plant-1 and dry matter accumulation were increased with increase in the levels of nitrogen and phosphorus up to 25 kg N ha-1 + 30 kg P2O5 ha-1. However, 35 kg N ha-1 + 40 kg P2O5 ha-1 resulted significantly higher protein and oil content of kernels over other levels of nitrogen and phosphorus, while pod yield, haulm yield and kernel yield were at par with 25 kg N ha-1 + 30 kg P2O5 ha-1 during both the years.
背景:花生仁含有48-50%的食用油，25-34%的蛋白质，10-20%的碳水化合物，是维生素(E, K和B复合物)的丰富来源。花生是豆科油料作物，对磷、钙、硫的需要量较高。石膏在世界各地普遍用作花生钙和硫的来源。考虑到所有这些观点，本研究旨在找出春花生的最佳矿物质营养方法:2018年和2019年春季，在旁遮普农业大学农学系学生研究农场进行了为期2年的田间试验。实验是在分裂阴谋设计复制三次四级石膏(0、125、175和225公斤农业的结合两个石膏应用阶段(全在播种,播种50% + 50%在花起始阶段)的主要情节和三个水平的氮和磷(15公斤N农业+ 20公斤P2O5农业,25公斤N农业+ 30公斤P2O5农业和35公斤N农业+ 40公斤P2O5农业的阴谋论调。结果:施用225 kg ha-1石膏显著高于其他石膏水平的生长参数、荚果产量、秸秆产量和籽粒产量。裂施的生长参数、荚果产量、秸秆产量和籽粒产量均显著高于基施。随着氮磷水平的增加，出苗数、株高、分枝数和干物质积累均增加，氮磷水平可达25 kg N ha-1 + 30 kg P2O5 ha-1。而35 kg N hm -1 + 40 kg P2O5 hm -1处理的籽粒蛋白质和油脂含量显著高于其他氮磷处理，籽粒产量、秸秆产量和籽粒产量均与25 kg N hm -1 + 30 kg P2O5 hm -1处理相当。

Background: To explore the impact of agronomic practices on nodulation, nitrogenase activity and biological nitrogen fixation in hybrid pigeonpea, a field investigation was under taken at BW5 block ICRISAT development center (IDC), International Crops Research Institute for Semi-Arid Tropics (ICRISAT), Patancheru, Hyderabad, during kharif, 2021 and 2022. Methods: The seedlings were raised in portrays in advance to onset of monsoon during last week of May (28th May in 2021 kharif and 30th May in 2022 kharif) in both the years by filling portrays with cocopeat and vermicompost in 1:1 ratio. Transplanting of 24 days and 25 days old seedlings were done on 20th June in 2021 kharif and 23th June in 2022 kharif, respectively, on the same day of dibbling in the main field at 100 cm × 100 cm ,120 cm × 120 cm square geometry and 150 cm × 60 cm. Nutrient management treatments were imposed one week after sowing. Result: Among the planting methods higher nodule number and nitrogenase activity with transplanting compared to dibbling. 120 cm × 120 cm found higher nodule number plant-1 and nitrogenase activity but biological nitrogen fixation was higher with 100 cm × 100 cm ha-1 basis. With respect on nutrient management practices, control performed well in terms of higher nitrogenase activity and biological nitrogen fixation and on par with integrated approach of 100% soil test based NPK + vermicompost + PSB + seed treatment with Rhizobium. So, with transplanting method of establishment, 100 ´ 100 cm square plant geometry and 100% soil test based NPK + vermicompost + PSB + seed treatment with Rhizobium was recommended agronomic practices for hybrid pigeonpea.
