Three fertility gradient stripes were created in Inceptisols of Odisha by applying no fertilizer, recommended dose of fertilizer (RDF) and double of the RDF and rice was grown during kharif, 2018 in the Central Research Farm of OUAT, Bhubaneswar. These three stripes were subdivided into 24 sub-plots and cucumber was grown with different graded doses of fertilizers and manures during rabi, 2018-19. Initial soil nutrient status, nutrient uptake, nutrient requirement, soil efficiency, fertilizer efficiency, organic matter efficiency and yield data were recorded. The highest cucumber yield (118.2 q ha-1) was obtained with 70 kg N, 40 kg P2O5 and 100 K2O ha-1. Fertilizer prescription equations were derived for targeted yield of cucumber in Inceptisols of Odisha. Nutrient requirement for producing of one quintal of cucumber yield on this technique is 0.44, 0.15, and 0.63 kg N, P2O5 and K2O. This enables the farmers to make the most efficient and profitable use of the costly inputs in farming.

Forty-three bell pepper genotypes collected from indigenous and exotic sources were evaluated during summer-rainy season, 2018 at Palampur to estimate genetic parameters of variability, heritability, genetic advance and correlation coefficient for yield and quality characters. Results revealed that significant variations were found among genotypes, indicating that yield and quality traits have enough variations. For all the traits studied, recorded values of phenotypic coefficients of variation (PCV) were greater than genotypic coefficients of variation (GCV). GCV was shown to be highest for marketable fruit yield per plant followed by capsanthin content and heritability was observed to be highest for capsanthin content followed by vitamin C. The three characters viz., marketable fruit yield per plant, capsanthin content, and vitamin C have shown high heritability coupled with high genetic advance as a percentage of mean suggesting the predominance of additive genetic control. High heritability coupled with moderate genetic advance was observed in pericarp thickness and TSS indicated the role of slightly additive gene action. Although TSS had a significant negative correlation with Vitamin C, the capsanthin content showed a positive correlation. Vitamin C and capsanthin content had a strong positive correlation with pericarp thickness; however, TSS had a significant negative correlation. There was no significant association between any of the quality parameters and marketable fruit yield per plant indicating that these traits can be improved independently.

Field experiment was carried out during 2018 and 2019 in a rice-green gram cropping system to study the effect of phosphorus (P) management in kharif rice under acidic Alfisols of Odisha, India. The experiment was conducted in split-plot design with three replications. Four main plots viz., P1-100% of soil test dose (STD) for P as basal to rice, P2- 100% of STD for P to both the crops, P3-50 % of STD for P to rice and 100% of STD for P to green gram, P4 -100% of STD for P to both the crops applied to green gram were allotted to the main plots and three rice varieties viz., V1-Mandakini, V2-Lalat and V3- Pratikhya were considered in the sub plots. Application of 100% STD for P to both the crops (P2) resulted in the highest grain and straw yield (3981 and 4715 kg ha-1, respectively). Rice variety Pratikshya maturing in 145 days produced the highest grain and straw yields of 3808 and 4399 kg ha-1, respectively. The grain quality parameters of rice like protein content (6.75 %), amylose content (20.36 %) and alkali value (4.60) were found highest in P2 which was significantly different from other P management practices. Rice variety Pratikshya produced a better quality grain like protein (6.63 %), amylose (20.28 %) and alkali value (4.56). Significantly highest total chlorophyll content (4.61 mg g-1 fresh leaves) was also observed with P2 among the P management practices and a value of 4.46 mg g-1 fresh leaves chlorophyll content was recorded in rice variety Pratikhya. Microbial biomass carbon increased up to 30 days after transplanting (DAT) and decreased thereafter up to 45 DAT irrespective of phosphorus doses and rice varieties. The soil dehydrogenase activity was increased due to application of different doses of phosphorus and rice variety irrespective of growth stages. P uptake by rice was estimated highest with P2 (100% of STD for P to both the crops) and cv. Pratikhya responded better among the varieties.

The present study was conducted to assess the general combining ability effects of parents and specific combining ability effects of crosses for yield and yield contributing traits in maize hybrid development. Combining ability studies were conducted in10 X 10 half diallel fashion at Prayagraj to determine GCA and SCA effects of parents and single crosses respectively. The economic heterosis (hc) revealed that the hybrids CM- 124 x LM-13, HKI-193-2 x CM 129, DMR-QPM-28 x CM- 124, HKI-193-2 x POP 445 and CML 41 x POP 445 showed positive significant results across the three environments E1, E2 and E3. The combining ability study indicated that the parents, HKI-193-2 (P10)LM 13(P6) and line CM 129 (P5) can be considered as good general combiners and genetically worthy parents, as they contributed favourable genes for grain yield. The parent CML- 41 (P9) was a good general combiner for the trait chlorophyll content in all three environments, while the parent LM 13 (P6) was a good source for favourable alleles for leaf area index since they had significant positive gca effects.The parents HKI-193-2 (P10)LM 13(P6)can be considered as good general combiners for protein content.The pooled analysis of variance over three environments revealed the mean sum of squares due to genotypes was significant for the characters studied. The hybrid CM- 124 x LM-13 showed good specific combining ability effects for grain yield,days to 50 % tasseling, days to 50 % silking, days to 50% maturity, 100 seed weight, chlorophyll content, leaf relative water content, leaf area index, leaf area ratio and protein content.The hybrid HKI-193-2 x CM 129 showed good specific combining ability effects for grain yield, days to 50% maturity, one hundred seed weight, leaf area index, leaf area ratio and starch content.

Based on the findings of the study, it can be concluded that seed invigoration with 10% herbal kunapajala was the most effective method over no priming and hydropriming to improve seedling vigour parameters of chickpea. However, hydropriming and 10% herbal kunapajala priming seems to enhance germination and enzymatic activity significantly over no priming.

The present investigation was conducted during therabi season of 2017-18 at the research farm of CSK HPKV, Palampur (Himachal Pradesh). The effect of target yield based fertilizer application on productivity, profitability, and nutrient uptake by wheat were evaluated in a randomized block design with eight treatments. The results revealed that the continuous cropping for 10 years along with STCR based fertilizer application in target yield 35 q ha-1 + 5 t FYM ha-1 recorded the highest grain yield (34.9 q ha-1) followed by target 35 q ha-1 (31.6 q ha-1).The highest protein content (12.6 %) and protein yield (441.4 Kg ha-1) of wheat grains were observed with target yield of 35 q ha-1 + 5 t FYM ha-1. Further, the maximum net profit of Rs.61401 ha-1 with a B: C ratio of 3.29 was obtained under target yield 35 q ha-1. A significant increase in N, P, and K uptake by wheat grain and straw was observed in STCR based target yield plots as compared to soil test based, general recommended dose, farmers’ practice, and control. The available N, P, and K content in post-harvest soil were reduced in the control over their initial values. The higher values of available N (305 kg ha-1), P (70 Kg ha-1) and K (290 kg ha-1) were recorded with target yield of 35 q ha-1 + 5 t FYM ha-1.
本调查是在2017-18年的雨季在喜马偕尔邦Palampur的CSK HPKV研究农场进行的。采用8个随机区组设计，评价了目标产量施肥对小麦生产力、盈利能力和养分吸收的影响。结果表明，连续种植10年，以目标产量35 q ha-1 + 5 t FYM ha-1施肥，籽粒产量最高(34.9 q ha-1)，其次是目标35 q ha-1 (31.6 q ha-1)。目标产量为35 q ha-1 + 5 t FYM ha-1时，小麦籽粒蛋白质含量最高(12.6%)，蛋白质产量最高(441.4 Kg ha-1)。在目标产量为35 q ha-1时，获得了Rs.61401 ha-1的最大净利润，B: C比率为3.29。与土壤试验、一般推荐剂量、农民实践和对照相比，以STCR为基础的目标产量小区小麦和秸秆对N、P和K的吸收显著增加。采后土壤有效氮、磷、钾含量在对照中较初始值有所降低。速效氮(305 kg hm -1)、磷(70 kg hm -1)和钾(290 kg hm -1)较高，目标产量为35 q hm -1 + 5 t FYM hm -1。

A field experiment was conducted during winter season of 2016-17 and 2017-18 to evaluate the effect of residue mulch and irrigation on the physiological response and yield of maize and soil physical properties at G. B. Pant University of Agriculture and Technology, Pantnagar. The experiment was laid-out in split-plot design which includes three irrigation scheduling in main plots and four residue mulch practices in sub plots. Soil temperature at 15 cm enhanced by 0.6-9.8 0C under mulch and by 0.7-1.2 0C with irrigation at 20% DASM over other irrigation levels. Mulch significantly decreased bulk density by 1.43-3.59% while increased saturated hydraulic conductivity by 3.8-41.0% and mean weight diameter by 6.0-20.0%. Irrigation at less depletion of available soil moisture favoured soil physical properties. Mulch and increase in irrigation frequency tended to increase in relative water content and transpiration rate while decreased leaf diffusive resistance. No noticeable differences in leaf temperature were observed under mulch and irrigation. Green gram straw mulch and irrigation given at 20% DASM produced 2.6-14.2 % and 1.3-9.2% higher grain yield, respectively. Combined application of green gram straw mulch @ 5 t ha-1 along with irrigation at 20% DASM was found most beneficial for maintaining favourable soil environment and can be recommended for obtaining higher maize yield in Mollisols

Irrigation at less depletion of available soil moisture favoured soil physical properties. Mulch and increase in irrigation frequency tended to increase in relative water content and transpiration rate while decreased leaf diffusive resistance. No noticeable differences in leaf temperature were observed under mulch and irrigation. Green gram straw mulch and irrigation given at 20% DASM produced 2.6-14.2 % and 1.3-9.2% higher grain yield, respectively. Combined application of green gram straw mulch @ 5 t ha-1 along with irrigation at 20% DASM was found most beneficial for maintaining favourable soil environment and can be recommended for obtaining higher maize yield in Mollisols","PeriodicalId":8031,"journal":{"name":"Annals of Plant and Soil Research","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"89774707","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}

A field experiment was conducted during 2016-18 on an Inceptisol of Rahuri, Maharashtra to study the effect of cogenerated bagasse ash on microbial population and enzyme activities in preseasonal sugarcane (Sachharum officinarum) var. CoM 0265. The results indicated that the treatments which received 150 % RDK through cogenerated bagasse ash recorded the higher total bacteria (44.11, 45.89 and 32.78 cfu x 106 g-1 soil), fungi (17.78, 18.89 and 15.89 cfu x 105 g-1 soil) and actinomycetes (18.33, 19.22 and 15.78 cfu x 105 g-1 soil) count at earthing up, grand growth and harvest stage of preseasonal sugarcane, respectively. On the other hand, the highest dehydrogenase (13.38, 14.03 and 7.92 µg TPFg-1 soil h-1), urease (49.35, 51.68 and 38.15 µg NH4-N g-1 soil h-1), acid phosphatase (17.92, 18.85 and 13.23 µg PNP g-1 soil h-1) and alkaline phosphatase (64.81, 65.94 and 39.07 µg PNP g-1 soil h-1) enzyme activity in soil were also recorded in T9 (150 % RDK through cogenerated bagasse ash) at earthing up, grand growth and harvest stage of preseasonal sugarcane, respectively. The results of the present study revealed that the microbial population and enzymatic activities of the soil were increased at initial stages and thereafter, progressively decreased with crop growth stages by the application of cogenerated bagasse ash. Application of 150 % RDK through CBA (6.62 t ha-1) along with recommended dose of nitrogen and phosphorous (340 and 170 kg ha-1) through inorganic fertilizers and 20 t ha-1 FYM has improved the microbial population as well as enzymatic activities in sugarcane grown soil.
2016- 2018年，在印度马哈拉施特拉邦Rahuri的一株Inceptisol上进行了田间试验，研究了甘蔗渣渣渣对季前甘蔗(Sachharum officinarum) var. 0265微生物种群和酶活性的影响。结果表明，施用150%甘蔗渣渣的处理在甘蔗育成期、盛期和收获期的总细菌(44.11、45.89和32.78 cfu × 106 g-1土壤)、真菌(17.78、18.89和15.89 cfu × 105 g-1土壤)和放线菌(18.33、19.22和15.78 cfu × 105 g-1土壤)数量均较高。另一方面，脱氢酶(13.38、14.03和7.92µg TPFg-1土壤h-1)、脲酶(49.35、51.68和38.15µg NH4-N g-1土壤h-1)、酸性磷酸酶(17.92、18.85和13.23µg PNP g-1土壤h-1)和碱性磷酸酶(64.81、65.94和39.07µg PNP g-1土壤h-1)酶活性在T9 (150% RDK通过甘蔗渣灰)土壤中也分别达到了最高水平。本研究结果表明，施用甘蔗渣灰后，土壤微生物数量和酶活性在作物生长初期增加，随后随着作物生长阶段逐渐降低。通过CBA施用150% RDK (6.62 t hm -1)，通过无机肥料施用推荐剂量的氮和磷(340和170 kg hm -1)和20 t hm -1 FYM，改善了甘蔗种植土壤的微生物数量和酶活性。

A field experiment was conducted during kharif season of 2019 at research farm of ICAR–Indian Agricultural Research Institute, New Delhi, India, to study the effect of GreenSeeker(GS) based nitrogen management and its interaction with water on growth and productivity of maize (Zea mays L.) var. PMH-1 under conservation agriculture. The experiment was laid out in split-split plot design withtwo crop establishment techniques (CET) viz. conservation agriculture (CA) and conventional tillage (CT) in main plots three irrigation regime (IR) in sub-plotsirrigation at critical growth stages, irrigation at 25% depletion of available soil moisture (DASM) and irrigation at 50% DASM, and four levels of nitrogen (N) in sub-sub plots; no-N applied, 33% N as basal, 33% N at knee high stage and 34% N at silking stage, 50% basal + rest N as guided by Green Seeker (GS) and 75% as basal + rest N as guided by GS. The results showed that GS based N application outperformed over farmers fertilizer practices in terms of growth and productivity, and its interactionalso significantly differed with irrigation scheduling. The maximum value of grain yield (6.9 tha-1), plant height at tasseling (173 cm) and harvest (235 cm), leaf area index at knee high stage (2.11) and silking (4.10), crop growth rate (8.4 and 9.2 gm-2day-1) at 0-30 and 30-60 days after sowing, respectively and NDVI (0.748), were recorded under75% as basal + rest N as guided by GS, over other practices and interaction effect with irrigation at 25% depletion of available soil moisture.
2019年农作季，在印度新德里icar -印度农业研究所研究农场进行了田间试验，研究了保护性农业条件下基于GreenSeeker(GS)的氮素管理及其与水分互作对玉米(Zea mays L.) var. PMH-1生长和生产力的影响。试验采用分畦式小区设计，主小区采用保护性农业(CA)和常规耕作(CT)两种作物建立技术(CET)，次小区采用3种灌溉方式(IR)，关键生育期采用土壤有效水分枯竭25%灌溉和土壤有效水分枯竭50%灌溉，次小区采用4种氮素水平;免施氮肥，33%施基氮，33%施膝高期施氮，34%施丝期施氮，绿色导引剂(Green Seeker, GS)引导50%施基+休养氮，GS引导75%施基+休养氮。结果表明，GS基施氮在生长和生产力方面优于农户施肥方式，其相互作用与灌溉调度也存在显著差异。以GS为指导，在75%以下的基础+静氮条件下，与其他措施和25%有效水分耗用灌溉的交互作用下，籽粒产量(6.9 kg -1)、抽雄时株高(173 cm)和收获(235 cm)、高膝期叶面积指数(2.11)和出丝量(4.10)、作物生长率(8.4和9.2 gm-2day-1)和NDVI(0.748)的最大值均低于75%。
