Study of nutrients uptake kinetics in crop plants is very important to determine the need of nutrients during crop growing period at a specific time, which relies upon a wide variety of factors, like plant species and their varieties, environmental conditions, soil properties, nutrients supply and soil microorganism etc. Therefore, to study the uptake kinetics of micronutrients, field experiments were carried out on sandy loam soil of Typic Haplustepts with six N levels i.e. 0, 40, 60, 80, 100 and 120 kg ha-1 and compared with absolute control. Uptake of micronutrients and their uptake rate was calculated at 11-60, 61-90, 91-120 and 121-180 day interval. Result revealed that the uptake of iron, zinc, manganese and copper increased with increased levels of applied nitrogen and advancing age of crop plants. It was highest at 120 kg N ha-1 during 121-180 days after sowing (DAS). Uptake of Fe and Mn was exponential while Cu was linear up to 180 days, whereas Zn made plateau beyond 120 DAS of the crop. Uptake rate of Fe and Cu showed linear pattern with increasing levels of N (upto 120 N kg ha-1) at all the four stages of the crop. However, uptake rate of Mn and Zn was different with rates of N application and was nearer to the linear trend up to 91-120 DAS. Fe uptake rate was remarkably higher during 121-180 DAS over the 91-120 DAS with all the levels of applied N. Uptake rate of Mn drastically reduced during 121-180 DAS than 91-120 DAS with all the levels of N. Hence, it can be concluded that application of N have positive response for uptake and uptake rate of micronutrients in fennel irrespective of growth stages, while uptake rate of Mn and Zn varied with stageswhereas the uptake rate of Fe and Cu continued, or even increased after plant senescence appeared, reflects that Zn and Mn are more responsible for growth of areal parts of fennel and Fe and Cu for root growth. Hence later stage application of Zn and Mn may be discouraged, while Cu and Fe application may continue for higher yield, nutrients use efficiency andratooning. Whereas, Mn and Zn uptake rate reduced with senescence of crop. This is because of fennel is an ‘Herbaceous perennial bushy’ plant and root remains active even beyond the senescence of aerial part of crop.
作物植物养分吸收动力学的研究对于确定作物在特定时期的生长期对养分的需求具有重要意义,这取决于多种因素,如植物种类及其品种、环境条件、土壤性质、养分供应和土壤微生物等。因此,为了研究微量元素的吸收动力学,在典型单步沙地壤土上进行了6个N水平(0、40、60、80、100和120 kg ha-1)的田间试验,并与绝对对照进行了比较。分别于11 ~ 60、61 ~ 90、91 ~ 120和121 ~ 180 d计算微量营养素的吸收量和吸收率。结果表明,铁、锌、锰和铜的吸收随施氮量的增加和作物年龄的延长而增加。播后121 ~ 180 d以120 kg N hm -1最高。在180 d内,铁和锰的吸收呈指数增长,铜的吸收呈线性增长,而锌的吸收在120 d后呈平稳增长。铁和铜的吸收速率随施氮量的增加呈线性关系(最高可达120 N kg hm -1)。而Mn和Zn的吸收速率随施氮量的增加而变化,在91 ~ 120 DAS时更接近线性趋势。铁吸收速率显著高于在91 - 120年期间121 - 180 DAS DAS的水平应用N吸收Mn率大幅减少比91 - 120年期间121 - 180 DAS DAS的水平N .因此,可以得出结论,应用N有积极响应微量营养物质的摄取和吸收速率茴香无论增长阶段,而吸收锰和锌的吸收速率随stageswhereas铁和铜继续、甚至在植株衰老后增加,反映Zn和Mn对茴香面部生长的作用更大,Fe和Cu对根部生长的作用更大。因此,后期可能不建议施用锌和锰,而继续施用铜和铁,以获得更高的产量,养分利用效率和再生。而锰、锌吸收速率随作物衰老而降低。这是因为茴香是一种多年生草本灌木植物,即使在作物的地上部分衰老之后,根部仍保持活跃。

An investigation was carried out to the study the impact of long-term organic farming practices on yield and uptake of nutrients by rice in an acid soil of Assam. The seven treatments were evaluated in randomized block design with three replications. The treatments consisted of T1; Absolute control, T2; Biofertilizer consortia @ 3.5 kg ha-1, T3; Compost @ 5.0 t ha-1, T4; Compost @ 5.0 t ha-1+ Biofertilizer consortia @ 3.5 kg ha-1), T5; Enriched compost @ 2.5 t ha-1, T6: Enriched compost @ 5 t ha-1, T7: Azolla @ 0.5 t ha-1 + Biofertilizer consortia @ 3.5 kg ha-1. Result revealed that significantly higher grain and straw yields were recorded as 34.5 and 57.1 q ha-1 with use of enriched compost @ 5.0 t ha-1 treatments. The grain yield of rice was increased by 14.6 and 43.1% over compost @ 5.0 t ha-1 and control, respectively and statistical similar grain yield was obtained with compost @ 5.0 t ha-1+biofertilizer consortia @ 3.5 kg ha-1 treatment. Application of enriched compost @ 5 t ha-1 significantly improve total nitrogen phosphorus and potassium uptake by rice and found similar to compost @ 5.0 tha-1 + biofertilizer consortia @ 3.5 kg ha-1 (except total K uptake) as compared to other treatments. Total uptake of micronutrient (Zn, Fe, Mn and Cu) by rice significantly enhanced with the use of organic farming practices over control. Thus, the dose of compost could be reduced by using enriched compost to obtain higher crop production with its quality.

Crop wild relatives are a good source of useful alleles for climate change adaptation. In present investigation, seven oat wild relatives (OWRs) including different Avena species tested against one commercial check of cultivated species A. sativa across three consecutive cropping seasons (Rabi 2018-19 to 2020-21) prevalent in North-western Himalayas at CSKHPKV, Palampur. Stability analysis was performed using Eberhart and Russell model for sixteen seed, forage yield and quality attributes. The mean squares for GE interaction were significant for most of the traits indicating differential response of genotypes to different environments. Both linear and non-linear components significantly contributed to genotype × environment interactions. Higher mean over commercial check, above average responsiveness with wider adaptable or stable genotypes identified were HFO 103 (A. orientalis) for seeds per panicle, HFO 498 (A. longiglumis) for harvest index and all the genotypes for protein content. Thus, these selected OWRs found stable and well adapted to all the types of climatic conditions of humid sub-temperate climate could be exploited in future breeding programme

Drought is a serious concern in agriculture, affecting yields all around the world, and is becoming a major source of food scarcity in many nations. The genetic potential of twelve different sorghum genotypes for drought tolerance and germination was evaluated at Sardarkrushinagar Dantiwada Agricultural University in 2018. Water stress was created by employing non-ionic PEG-6000 to lower water potential. The experiment was set up using a complete randomized design with three replications. The experiment included twelve distinct sorghum genotypes with four different PEG-6000 treatments ((S1) 0%, (S2) 5%, (S3) 10%, and (S4) 15% treatment). Our goal in this study was to evaluate 12 sorghum genotypes based on physiological responses as well as drought tolerance. Germination percentage, shoot length, root length, shot dry weight, root dry weight, seedling vigour index, and Root: Shoot ratio were all traits evaluated. Significant differences were observed among the treatments in all 12 sorghum genotypes and genotypeDS-183 was more tolerant to simulated drought stress with PEG-6000 than other sorghum genotypes

Pigeonpea (Cajanus cajan (L.) Millsp.), an important grain-legume of semi arid tropics is severely attacked by many insect species, resulting in losses of quantity and nutritional quality. In the present study, fifteen long duration genotypes of pigeonpea were assessed against the attack of M. obtusa, C. gibbosa and H. armigera for two years (2017-2018 and 2018-19) in Varanasi. Resistance to pigeonpea genotypes was evaluated by measuring pod and grain damage per cent in accordance with their yields. Pest susceptibility rating revealed that none of the genotypes fell in resistant/highly-resistant categories. However, genotypes IVT-705, IVT-706 and IVT-907 were found to least susceptible for all the three insect pests (except for IVT-907 for C. gibbosa) and also showed higher yields. In other words, yield losses were lower in genotypes which shown less pod/grain damage by insects. Pod damage of some other genotypes viz. IVT-208 (M. obtusa-31.3%, C. gibbosa-12.6%, H. armigera¬-4.8%), IVT-12-904 (M. obtusa-29.5%, C. gibbosa-12.8%, H. armigera¬-7.3%) also accounted for their lower levels of susceptibility to the insect pest complex.

The genetic variability, heritability, genetic advance, correlation coefficient and path analysis were estimated for fibre yield and its attributing traits in fifty two germplasm lines of Jute (Corchorus olitorius L.) at Rahuri (M.S.) during kharif season of 2020. Higher magnitude of variance was recorded in plant height followed by days to 50% flowering, days to initiation of flowering and fibre yield per plant. The genotype OIN-136 recorded the highest fibre yield per plant along with higher green weight and basal diameter. The highest genotypic and phenotypic variance was for plant height, days to 50% flowering, days to initiation of flowering, fibre yield and basal diameter and the lowest genotypic and phenotypic variance was that of green weight. High values for PCV and GCV were recorded for green weight and fibre weight. High values of heritability were recorded for basal diameter, days to 50% flowering, days to initiation of flowering and plant height and moderate values of heritability were recorded for green weight and fibre yield. The genetic advance was highest for plant height and lowest for base diameter. The high heritability with moderate to high genetic advance over percentage of mean was observed in plant height, days to 50% flowering and days to initiation of flowering which indicate preponderance of additive genetic action. The high heritability with low genetic advance over percentage of mean was observed in basal diameter. Low heritability with low genetic advance over percentage of mean was observed in green weight and fibre yield indicated the presence of both additive and non additive gene effects. The magnitude of genotypic correlation was higher than the phenotypic correlation indicating that elimination of environmental effects led to strengthen genetic association. The correlation analysis revealed that there was a nonsignificant association of initiation of flowering with green weight and fibre yield at phenotypic level, plant height with green weight at phenotypic level and plant height with fibre yield at genotypic and phenotypic level. Green weight/ plant had highest positive direct effect on fibre yield per plant at genotypic and phenotypic level, days to 50% flowering at phenotypic and initiation of flowering at genotypic level. Therefore direct selection based on these characters would be feasible. Days to initiation of flowering at phenotypic, days to 50% flowering at genotypic, plant height at genotypic and phenotypic and basal diameter per plant at genotypic exhibited high and negative direct effects towards fibre yield. Significant positive correlations with fibre yield per plant indicated that the indirect selection could be made for high yielding jute genotypes through most of the characters having positive indirect effects.

A field experiment was conducted on clay loam soils at Regional Research Station, Chaudhary Charan Singh Haryana Agricultural University, Karnal, Haryana for three year (2018-2021) to investigate the effect of different organic treatments such as farmyard manure (FYM), bio fertilizers (BF) and green manuring (GM) with Sesbania or trash mulching (TM) on sugarcane yield, quality and soil fertility status. Cane length, cane girth, number of millable canes and commercial soluble sugar percent increased with the application of FYM, BF and GM/TM as compared to zero budget technique. The treatment that received 30 t FYM ha-1 +BF+GM/TM+ integrated pest management (IPM) recorded 15.8 and 12.3 % increase in cane yield over zero budget technique in plant and ratoon crops, respectively. Both in plant and ratoon crop, higher available nitrogen (145.7 and 147.8 kg ha-1), phosphorus (18.57 and 18.43 kg ha-1) and potassium (406.8 and 412.8 kg ha-1) were recorded where 30 t FYM ha-1 was applied along with BF+GM/TM+IPM. The application of 30 t FYM ha-1+BF+GM/TM+ IPM was found at par with treatment 20 t FYM ha-1+BF+GM+IPM for plant crop and 25 t FYM ha-1+BF+TM + IPM for ratoon crop. The treatment 20 or 25 t FYM ha-1 + BF + GM/TM + IPM were at par with the RDF treatment. The cane yield and juice quality obtained as a result of application of 20t FYM ha-1 + BF+GM+IPM for sugarcane plant crop and 25t FYM ha-1 +BF+TM+IPM for sugarcane ratoon crop was comparable with that of RDF.

An experiment was planned to visualize the impact of terminal heat stress on yield potentials of late sown mustard cultivars under the changing climatic conditions. A set of fifteen B. juncea genotypes were evaluated at two planting dates during two winter seasons. Late planted genotypes faced heat stress during post anthesis/seed filling stage which negatively influenced the movements of photosynthates to developing sinks thus inhibiting synthetic processes, lowering seed weight and seed yield and may even hamper seed quality. Onset of flowering and siliquing were delayed but the completion of flowering and siliquae formation was earlier in the late planted genotypes. Seed filling was impeded by high temperature in late planting causing ≥50% decline in seed yield. Average accumulated growing degree days (AGDD) for phenological stages were higher in normal sown than the late sown crop. AGDD witnessed an increasing trend for flowering and fruiting behaviour in both the sowing dates. However, 50% flowering in late sown crop took 4 accumulated GDDoC days more. Average heat use efficiency was found to be significantly higher in normal sown genotypes for seed (0.95 kg ha-1 ºC-days-1) and biological (0.53 kg ha-1 ºC-days-1) yield relative to the late sown genotypes for seed (0.50 kg ha-1 ºC-days-1) and biological yield (2.71 kg ha-1 ºC-days-1). Seed yield under late sown condition had positive and significant correlation with siliquing duration (r= 0.600*) and reproductive phase (r= 0.558*) whereas, negative with flowering completion (r= -0.573*) and siliqua initiation (r= -0.519*). Based on the results IAN was the best genotype for delayed sowings.
研究气候条件变化下末热胁迫对晚播芥菜品种产量潜力的影响。在两个冬季的两个种植日期对15个芥菜基因型进行了评价。晚播基因型在开花后灌浆期面临热胁迫,影响了光合产物向发育库的运动,从而抑制了合成过程,降低了种子重量和产量,甚至可能影响种子质量。晚播基因型的开花和结晶花发生时间较晚,而开花和结晶花形成时间较早。播后期高温影响种子灌浆,导致籽粒产量下降≥50%。物候期平均累积生长日数(AGDD)正常播种高于晚播作物。在两个播期,AGDD的开花和结果行为都呈增加趋势。而晚播作物50%开花多需要4天的累积GDDoC。正常播种基因型种子(0.95 kg ha-1ºc -d -1)和生物产量(0.53 kg ha-1ºc -d -1)的平均热量利用效率显著高于晚播基因型种子(0.50 kg ha-1ºc -d -1)和生物产量(2.71 kg ha-1ºc -d -1)。晚播条件下种子产量与结实期(r= 0.600*)和繁殖期(r= 0.558*)呈显著正相关,与开花完成期(r= -0.573*)和结实期(r= -0.519*)呈显著负相关。结果表明,IAN是延迟播种的最佳基因型。

A study was conducted on soil and plant nutritional status of guava orchards in order to identify the nutrients that are deficient / low by surveying 100 guava orchards, collection of leaf and soil samples in guava growing Agra district. In general, soils were alkaline in reaction and low in organic carbon. The range (mean) values of available N, P, K and S were 175.0 to 235.0 (196.5 kg ha-1), 8.5 to 24.0 (27.5 kg-1), 180.0 275.0 (218.5 kg ha-1) and 9.0 to 26.0 (15.5 kg ha1), respectively in orchard soils. As regards to DTPA extractable Fe, Mn and Cu, the status of these micronutrient cations was adequate in these soils. The soils of guava orchards were deficient in DTPA-Zn to the extent of 45 per cent. Most of the nutrients showed positive relationship with organic carbon content. These elements were negatively related with soil pH and calcium carbonate. The yield limiting nutrients differed from orchards to orchards though some of the nutrients were more prominent. The leaf samples were deficient in nitrogen, sulphur and zinc. On the other hand, P, K, Fe, Cu contents in majority of leaves were in optimum range in guava orchards. The ranges of nitrogen, phosphorus, potassium and sulphur content in guava leaves were from 1.55, to 2.18, to 0.16 to 0.32, 1.20 to 2.10 and 0.18 to 0.35 per cent, respectively. The corresponding ranges of micronutrient cations, i.e. Fe, Mn, Cu and Zn in guava leaves were from 145 to 242, 28.0 to 60.0, 4.5 to 10.6 and 17.5 to 35 mg kg-1.

Climate change and climatic variability are major over-riding concerns for Indian agriculture impacting ultimate farm profitability and sustainability.Both biotic and abiotic stresses are influenced by these phenomena. In the current study 13Trichoderma isolates were screened in-vitroat CRIDA - Hyderabad during 2018-2019, for their biotic and abiotic stress tolerance levels.In-vitro antagonistic activity with phytopathogens Macrophominaphaseolina (Mp), Fusariumoxysporumf.sp. ricini (FoR), Rhizoctoniasolani (Rs) and Sclerotiumrolfsii (Sr) revealed that T6,T7,T9,T12 and T13 isolates were most effective against Mp, FoR and Rs with 97-100% inhibition, in Rs T4, T12 and T13 with 69-75% inhibition were found to be best.In plant growth promotion traits, T5 was found to be the highest producer of IAA with 37.9g/mL, T6 and T8 produced the highest amounts of HCN (39.2ppm). Similarly ammonia was produced highest in T5 and T13 while in siderophore production was highest in T10 isolate with 80 SU. Under drought conditions, T3, T12, T11 and T13 isolates were tolerant up to -1.8MPa and in salinity conditionsT6, T12 and T13 isolates were resistant up to 220 dSm-1. T6, T12 and T13 isolates were found to sustain elevated temperatures up to 43°C. Most of the Trichoderma isolates were found to be effective antagonists and abiotic stress tolerant.
