A field experiment was carried out on acidic soil of Khowai district of Tripura during 2017 and 2018 to study the effect of application of various combinations of lime, farmyard manure (FYM), poultry manure (PM), and rhizobium with the recommended doses of NPK on groundnut (Arachis hypogaea L.) productivity. The experiment was conducted in a completely randomized block design with 13 treatments; each replicated thrice. The application of the recommended dose of NPK @ 20:60:40 kg ha-1 along with lime @ 1/5th Lime Requirement (LR), PM @ 5 t ha-1 and seed treatment with Rhizobium @ 20 g kg-1 of seed significantly increased the seed yield and recorded the highest Benefit : Cost ratio (B:C) compared to the recommended dose of NPK alone as well as other treatments combinations. Thus, in achieving higher groundnut productivity with better return in acidic soils of Tripura, integrated use of inorganic fertilizers (NPK @ 20:60:40 kg ha-1) combined with lime @ 1/5th LR, PM @ 5 t ha-1, and seed treatment with Rhizobium @ 20 g kg-1 of seed might be recommended.
2017 - 2018年，在印度特里普拉邦Khowai区的酸性土壤上进行了田间试验，研究石灰、农家肥、禽粪和根瘤菌在推荐氮磷钾剂量下施用对花生产量的影响。试验采用完全随机区组设计，共13个处理;每个复制三次。施用氮磷钾推荐剂量20:60:40 kg hm -1，同时施用石灰1/5石灰需用量(LR)、PM 5t hm -1和根瘤菌种子处理20 g kg-1，显著提高了种子产量，与单独施用氮磷钾推荐剂量和其他处理组合相比，取得了最高的效益:成本比(B:C)。因此，为了在特里普拉邦的酸性土壤中获得更高的花生产量和更好的回报，建议综合使用无机肥料(NPK @ 20:60:40 kg hm -1)，结合石灰@ 1/5 LR, PM @ 5t hm -1，以及根瘤菌@ 20 g kg-1种子处理。

Aims: To evaluate the effect of potassium nitrate (KNO3) on flowering and fruiting of mangoes in Uganda. Study Design: Randomized complete block design in a split plot arrangement. Place and Duration of Study: National Crops Resources Research Institute Namulonge, National Semi–Arid Resources Research Institute in Serere and Bulindi Zonal Agricultural Research and Development Institute in Hoima in 2015 and 2016. Methodology: The study was superimposed on eight-year-old mango orchards which were simultaneously planted at the three sites. Main plot treatments comprised three mango varieties (Bire, Tommy Atkins, Zillate), while sub-plot treatments comprised four concentrations of KNO3 (zero as control, 1, 2 and 4%). Data was collected on number of terminal buds induced after applying KNO3, percentage flowering, number of fruits set per 20 panicles and fruit yield per tree. Results: Trees sprayed with KNO3 produced higher (P < .05) numbers of terminal buds than the control. Across sites, Bire produced higher numbers of buds (64.8) than Tommy Atkins (46.3) and Zillate (17.8). Flowering response was higher in Bire (28.6%) than in Tommy Atkins (20.8%) and Zillate (17.8%). Flowering response of trees sprayed with 2% KNO3 (31.4%) was higher than that of trees sprayed with 1% KNO3 (24.7%). Mean number of fruits induced per 20 panicles in trees sprayed with 4% KNO3 (8.24) was higher than that of trees sprayed with 1% KNO3 (4.8). Fruit yield of Tommy Atkins (23.01 kg/tree) was higher than that of Bire (10.97 kg/tree). Mean fruit yield of trees sprayed with 2% KNO3 (27.36 kg/tree) was higher than that of trees sprayed with 1% KNO3 (15.93 kg/tree). Conclusion: For better fruit yields, farmers at Bulindi should grow Tommy Atkins and apply 2% KNO3. Farmers at Namulonge can grow any of the three mango varieties and apply 2 or 4% KNO3, while those at Serere can grow Tommy Atkins and Zillate, and should apply 4% KNO3.

A field experiment was conducted at College Farm, Navsari Agricultural University, Navsari (India) to assess the association and interrelationship of various growth and yield attributing traits that determine seed yield of sesamum. The experiment was carried out in randomized block design with four replications and nine treatments viz., T1: sole sesamum, T2: sole sesamum (Paired rows at 30-60 cm), T3: sole sesamum (Paired rows at 30-30-75 cm), T4: sole green gram, T5: sole cowpea, T6: sesamum + green gram (paired 2:1), T7: sesamum + green gram (paired 3:2), T8: sesamum + cowpea (paired 2:1) and T9: sesamum + cowpea (paired 3:2). Results showed that seed yield of sesamum was significantly affected and positively correlated with growth characters viz., number of branches/plants at 45 DAS (r=0.656**), harvest (r=0.545**), dry matter accumulation at 45 DAS (r=0.687**) and harvest (r=0.553**). Various yield attributing traits viz., number of capsules/plants (r=0.671**), capsule length (r=0.618**), number of seeds/capsules (r=0.672**) and test weight (r=0.704**) significantly influenced the seed yield of sesamum. Sesamum equivalent yield was also significantly and positively correlated with available N, P and K status of soil. Regression studies indicated that the yield variations in seed yield of sesamum due to yield attributes to a great extent (80 to 98%). Overall, it can be concluded that better growth and yield attributing traits caused significant and positive improvement in seed yield of sesamum as well as its equivalent yield.

Pseudomonas (P) fluorescens promote plant growth by lowering the endogenous ethylene synthesis in the roots through their 1-aminocylopropane-1-carboxylate-deaminase (ACCD) activity. However, in the environs of the roots may decrease the efficiency of these P. fluorescens by stimulating ACC- oxidase activity resulting in greater ethylene production by the roots. So this study was designed to assess the performance of P. fluorescens containing ACC-deaminase for improving rhizobial population and yield of maize. The results revealed that the rhizobial population, irrespective of treatments, was maximum at 55 days after sowing followed by a reduction at harvest. The treatment T28+pH 7.2 (Temperature 28°C + pH 7.2) enhanced the maximum population of P. fluorescens in rhizoshpere at 35, 55 and 75 days after sowing (DAS) was with 1.69, 1.59 and 1.87 log fold increase over fertilized un-inoculated FUI [(3.7089 log cfu/g = 5.80 x103 cfu g-1 soil), (5.8673 log cfu/g = (7.53x105 cfu g-1 soil) and (4.676 log cfu/g 5.55x104 cfu g-1 soil)]. Similar treatment T28+pH 7.2 recorded maximum number of cob plant-1, cob length-1, number of grains line-1 and number of grains cob-1 at harvest were with T28+pH 7.2 by 30.6, 32.1, 29.7 and 37.7% over the control FUI (2.1, 15.2 cm, 35.0 and 503), respectively. While the treatment T31+pH 7.2 (Temperature 31°C + pH 7.2) enhanced the cob girth and maximum grains line cob-1 at harvest were with 26.0 and 31.3% response over FUI (13.3 cm cob-1 and 13.9), respectively. The treatment T28+pH 7.2 significantly increased the seed and stover yields of maize by 24.9 and 31.6% over the control (2914 and 7133 kg ha-1), respectively.

World agriculture is facing increasing demand due to multiple challenges. The biggest challenge is to attain food security in the ever increasing growing population. Rice (Oryza sativa L.) is a staple food crop for half of the world's population and one of the world's most significant food crops. Farmers must produce more rice with enhanced quality in order to ensure food security in rice-consuming countries across the world. Rice (Oryza sativa L.) is considered to be a Si accumulator plant and tends to actively accumulate Si into tissue up to concentrations of 5% or even higher. The present study aimed to use different forms of N and Si sources at different levels to improve the growth traits contributing to the increase yield of rice. A pot experiment was conducted in glasshouse, TNAU, Coimbatore to assess the response of nitrogen and silica on paddy during October 2020 – January, 2021. The treatments comprised of the two factors, nitrogen and silica with three replications. The growth parameters like plant height, number of tillers per plant and total dry matter production were recorded at all stages and yield traits at harvest stage. The treatment, T11 - N2S2 (53.4 and 110.2 g pot-1 respectively) significantly enhanced the grain yield (34%) and straw yield (40%) than control in the pot experiment. Highest growth and yield parameters were recorded with application of combined fertilization of nitrogen and silica (T11-N2S2) which comprises150 kg ha-1of urea and 200 kg ha-1 of calcium silicate compared to control.
由于多重挑战，世界农业面临着日益增长的需求。最大的挑战是在不断增长的人口中实现粮食安全。水稻(Oryza sativa L.)是世界一半人口的主要粮食作物，也是世界上最重要的粮食作物之一。农民必须生产更多质量更高的大米，以确保世界各地大米消费国的粮食安全。水稻(Oryza sativa L.)被认为是一种硅积累植物，当硅含量达到5%甚至更高时，水稻会主动向组织中积累硅。本研究旨在利用不同形态、不同水平的氮、硅源，改善水稻的生长性状，促进产量的提高。2020年10月- 2021年1月，在哥印拜陀(Coimbatore) TNAU的温室进行了盆栽试验，研究了氮素和二氧化硅对水稻的响应。处理由氮和二氧化硅两个因素组成，重复3次。记录各生育期株高、单株分蘖数、总干物质产量等生长参数和收获期产量性状。在盆栽试验中，T11 - N2S2处理(分别为53.4和110.2 g)比对照显著提高了籽粒产量(34%)和秸秆产量(40%)。氮肥与二氧化硅(T11-N2S2)配施150 kg ha-1尿素和200 kg ha-1硅酸钙，与对照相比，取得了最高的生长和产量参数。

Agriculture University, Jobner, Jaipur, Rajasthan, to get a suitable combination of sowing at different plant geometries and weed management. The experiment was managed in a split-plot design with three replications. The main plot treatments comprised four plant geometries, viz. 50 x 20 cm, 50 x 25 cm, 60 x 15 cm and 60 x 20 cm and subplots consisted of six treatments of weed management, viz. weedy check, two hand weeding (HW) at 25 and 50 days after sowing (DAS), pendimethalin @ 0.75 kg/ha pre emergence (PE), oxadiargyl @ 75 g/ha (PE), pendimethalin @ 0.75 kg/ha (PE) + one HW at 30 DAS and oxadiargyl @ 75 g/ha (PE) + one HW at 30 DAS. Sowing of fennel with plant geometry 60 x 20 cm showed superior performance in respect of dry-matter accumulation, growth indices and yield as compared to plant geometries 50 x 20 cm, 50 x 25 cm and 60 x 15 cm. Among weed management treatments, hand weeding twice 25 and 50 DAS registered significantly highest dry matter accumulation, growth indices viz. crop growth rate (CGR), relative growth rate (RGR) and yield of fennel, thus, hold a great promise in fennel production under semi-arid conditions of Rajasthan.

Kingdom of Saudi Arabia (KSA) primarily relies depends mainly on groundwater for drinking and irrigation purposes. The study was therefore aimed to identify groundwater quality in Al-Jouf Region, KSA using water quality index (DWQI). In addition, investigating the hydro-chemical characteristics that control the groundwater quality. Groundwater samples were collected from 150 groundwater wells at a 300-500 m depth and subjected for chemical analysis. The values of chemical constituents were compared with the KSA and World Health Organization (WHO) standards for drinking and irrigation purposes. The results indicated that, the concentrations of ions were within the ranges of KSA for drinking water and WHO. Based on DWQI data, for drinking water about 23.9% of the wells were within poor water category (III), while 9.91% was very poor water within (IV) group, 45.6% is good water of group (II) and 20.5% is excellent water within category (I). Regarding the evaluation of water quality, the estimated DWQI values for the 150 well waters in Al-Jouf, region ranged from 40.7 to 319. About 23.9% of wells were considered poor water “class (III)”, 9.9% were very poor water “class (IV)”, 45.6% were good water for drinking or “class (II), and 20.53% were excellent water. The result shows that the groundwater possess moderate to high salinity hazards with low to medium sodium hazards. The piper diagram showed that cations were decreasing as follow: Na+>Ca2+>Mg2+, while the anions were decreasing as follow Cl− > HCO3− > SO42−>CO32-. The SAR values varied from 0.68 to 15.43; while Kelly’s ratio (KR) ranged between 0.32 to 4.02. The calculated IWQI values of all wells revealed that water was moderate type in which its value was between 22 to -27.

An experiment was conducted during rabi season of 2017-18 to estimate the genetic parameters of variation including heritability and genetic advance for agro-physiological characters viz., days to flower initiation, days to 50 per cent flowering, days to maturity, plant height, branches per plant, pods per plant, seeds per plant, biological yield per plant (g), seed yield per plant (g), 100-seed weight (g), root length (cm), relative water content and harvest index (%) in 20 genotypes of chickpea. High phenotypic coefficient of variance (PCV) and genotypic coefficient of variance (GCV) were observed for characters viz., number of branches per plant, seeds per plant and 100-seed weight. The magnitude of phenotypic coefficient of variance and their corresponding genotypic coefficient of variance for all the characters were observed in good agreement reflecting the narrow range of environmental influence in the manifestation of the characters. High heritability was recorded for number of branches per plant, 100-seed weight, seeds per plant, pods per plant and biological yield per plant. High heritability combined with high genetic advance was observed for seeds per plant, pods per plant and 100-seed weight which indicated that these traits were governed by additive gene effects and phenotypic selection would be effective in early generations for these characters.

An experiment was conducted during 2019 to study the jamun genotypes based on shelf life of fruit. Shelf life studies were conducted on eight jamun genotypes and results indicated that, the maximum shelf life of the Jamun fruit was 5 days under normal room temperature after harvest at ripened stage. Genotypes Dhoopdal, Selection-45 and Savadatti had better shelf life compare to other genotypes. In crossing (S. cumini × S. jambose), out of 100 crossed flowers, only 5 crossed flowers were set and produced fully mature fruits.
