Different methods to estimate electrical conductivity (EC) of saturated soil paste extract (ECe) of 1:2 and 1:5 soil: water suspensions were evaluated. Soil samples were taken from different depths (viz. 0-15, 15-30, 30-45, 45-60, and 60-90 cm) of the wheat field under irrigated saline regimes ranging from 1.5 to 12 dSm-1. The relationship between the electrical conductivity of saturated paste extract (ECe) and soil-water suspension extracts (i.e., EC1:2 and EC1:5) was established beside the development of regression models and conversion factors. Regression models relating ECe with EC1:2, EC1:5 were developed with coefficients of determination (R2) 0.98 and 0.99 respectively. The average conversion factor between ECe~ EC1:2 and ECe~ EC1:5 were 2.7 and 7.7, respectively. Methods standardized in the study can be used to estimate the EC of different saturated soil paste extract ratios, which will be less cumbersome and significantly reduce the estimation time.

Coleus (Solenostemon rotundifolius) is an important minor tuber crop grown in the homesteads of Kerala and Tamil Nadu. There was a demand for mechanisation for harvesting the tuber because the conventional method of harvesting followed was tedious and time-consuming. For the design and development of a coleus harvester with reduced drudgery, the design parameters were selected with respect to the tuber properties. Random sampling was carried out for determining the physical and frictional properties of coleus. The average values of physical properties such as length, width, thickness, geometric mean diameter, sphericity, surface area, volume and bulk density were found out as 44.56 mm, 27.36 mm, 24.50 mm, 30.99 mm, 0.70, 3029.69 mm2, 15786.50 mm3 and 718.21 kg m-3 respectively. The angle of repose was determined as 30.83° and the coefficient of static friction was found out as 0.73, 0.69 and 0.81 on galvanised iron, stainless steel and plywood surfaces respectively. These data were used for the design of various components of the harvester.

An experiment was conducted to study genetic variability, heritability and genetic advance among twenty varieties of chrysanthemum (Chrysanthemum morifolium Ramat.) at the College Farm, College of Horticulture, Department of Floriculture and Landscape Architecture, SDAU, Jagudan during 2020-21. A wide variation in performance of the varieties were recorded for various growth, flowering, yield and quality parameters and results shows that magnitude of the phenotypic coefficient of variation (PCV) was higher than genetic coefficient of variance (GCV). High GCV and PCV was recorded for fresh weight of flower followed by number of leaves per plant, number of flowers per plant, number of primary branches, shelf life, yield of flowers per plant and yield of flowers per plot. High heritability along with high genetic advance as per cent of mean was observed for number of leaves per plant, days to full bloom, number of flowers per plant, yield of flowers per plant and yield of flowers per ha. Further, these characters could be exploited for improvement through breeding programme.

New advances in information technology led to the development of Expert Systems and their application in various sectors including farming. In India, agricultural production has been transformed into a multifaceted business enterprise. Indian agriculture to remain competitive needs the accumulation and integration of scientific knowledge, and information from many diverse sources. Indian farmer often relies on agricultural specialists, advisors and agricultural research and development institutes for agricultural information for better decision making at the actual farm situation. Unfortunately, timely specialist assistance is not available when the farmer needs. Thus the situation demand for a ‘virtual expert’ who can give personalized expert advice to a large community of farmers, specific to their needs and aspirations considering various knowledge sources. The role of expert systems in tobacco sector and its applications in effective production and protection technologies have been discussed in this article. It is almost impossible for any human expert to consider every piece of available information before arriving at optimal decisions. To overcome this problem and provide precise information to the farmers, “expert systems” have been developed with a primary goal to make expertise available to clients and decision makers who need answers swiftly. The main aim is to deliver the required information and disseminate the up-to-date scientific knowledge in a readily accessible and easily understood form to the farmers. It is one of the most efficient extension tools to take the technology from scientists to the growers directly without any distortion of content which normally creeps in because of multiple agencies involved in conventional technology transfer systems. With this aim, ICAR-Central Tobacco Research Institute has developed a web-based expert system on tobacco using “Agridaksh”- an online tool developed by ICAR-Indian Agricultural Statistics Research Institute. This, online expert systems has the tremendous capacity to transfer location specific technologies and advice to the farmers with a greater precision

A field experiment was conducted to evaluate organic vis-à-vis inorganic fertilizers and soil sustainability in soybean-wheat cropping sequence for two consecutive years. Grain yield of both the crops, i.e., soybean (16.29 q/ha) and wheat (46.05 q/ha) was observed to be significantly superior by fertilizer application as per general recommended dose of respective crops. Integrated application of fertilizers i.e., inorganic fertilizers 50% and organic fertilizers 50% was found to be the next superior treatment to that of general recommended dose. Soil properties were improved by use of organic and inorganic fertilizers in combination. However, no significant change was observed in case of soil pH and electrical conductivity.

A field trial was conducted during the Kharif season of 2020 to assess the effect of spatial and temporal crop geometry on the phenology, yield and agro meteorological indices of hybrid maize at the Agronomy Research Farm, FoA Wadura, Sopore, SKUAST-Kashmir. The experiment was carried out in split- split plot design with dates of sowing (17th SMW; D1), 19th SMW; D2 and 21st SMW; D3) as main plot treatments; varied row spacing (50 cm × 20 cm; S1, 60 cm× 20 cm; S2 and 70 cm ×20 cm; S3) as sub- plot treatments and two maize hybrids (Hytech- 5801;H1 and YSH- 1; H2) as sub- sub plot treatments. Results indicated that hybrid Hyteh- 5801 sown on 17th SMW observed highest grain yield and biological yield and took greater days to reach different phenological stages, thereby piled higher heat units, PTUs, HTUs, HyTUs, PTI followed by 19th SMW and 21st SMW. The plant spacing of 70 cm ×20 cm took maximum days for reaching different phenophases and accumulated maximum heat units, PTUs, HTUs, HyTUs, PTI. Thermal use efficiencies were maximum ((HTUE, PTUE, HyTUE and HUE)) when the maize hybrid Hytech-5801was sown on 17th SMW. The biological yield based thermal efficiencies showed the highest response with row-spacing of 50 cm × 20 cm whereas grain yield based thermal efficiencies were maximum under 70 cm×20 cm plant spacing.

The experiment was carried out in split- split plot design with dates of sowing (17th SMW; D1), 19th SMW; D2 and 21st SMW; D3) as main plot treatments; varied row spacing (50 cm × 20 cm; S1, 60 cm× 20 cm; S2 and 70 cm ×20 cm; S3) as sub- plot treatments and two maize hybrids (Hytech- 5801;H1 and YSH- 1; H2) as sub- sub plot treatments. Results indicated that hybrid Hyteh- 5801 sown on 17th SMW observed highest grain yield and biological yield and took greater days to reach different phenological stages, thereby piled higher heat units, PTUs, HTUs, HyTUs, PTI followed by 19th SMW and 21st SMW. The plant spacing of 70 cm ×20 cm took maximum days for reaching different phenophases and accumulated maximum heat units, PTUs, HTUs, HyTUs, PTI. Thermal use efficiencies were maximum ((HTUE, PTUE, HyTUE and HUE)) when the maize hybrid Hytech-5801was sown on 17th SMW. The biological yield based thermal efficiencies showed the highest response with row-spacing of 50 cm × 20 cm whereas grain yield based thermal efficiencies were maximum under 70 cm×20 cm plant spacing.","PeriodicalId":14972,"journal":{"name":"Journal of AgriSearch","volume":"75 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-03-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"85120226","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}
An experiment was conducted to find out the combined effect of organic manures [farm yard manure (FYM), vermicompost, poultry manure and bone meal], macro nutrient (Sulphur) and micro nutrients (Boron and Zinc) on growth and yield of onion cv. N-53 in a Randomized Block Design with three replications. The results showed that maximum plant height (56.85 cm), maximum number of leaves (13.26),leaf length (50.45 cm), leaf width (1.51 cm), neck diameter (1.917), bulb length (7.06), bulb scale (8.300), bulb diameter before curing (6.167), bulb diameter after curing (5.263), bulb weight per plant (99.32 gm), bulb yield per plot (2.979 kg) and bulb yield per ha. (297.93 q)was recorded under the T10[FYM + Vermicompost + Poultry manure + Bone meal + Sulphur + Boron + Zinc]. While minimum plant height (44.13 cm), number of leaves (9.36), leaf length (39.39 cm), leaf width (1.31 cm), neck diameter (1.103), bulb length (4.18 cm), bulb scale (5.287), bulb diameter before curing (3.637), bulb diameter after curing (3.080), bulb weight per plant (45.470 gm), bulb yield per plot (1.364 kg) and bulb yield per ha.

A field experiment was conducted at Agricultural Research Station, Anand Agricultural University, Derol during the rabi and summer seasons of 2013-14 and 2014-15 to determine the effect of inorganic fertilizer, biofertilizers, and micronutrients, as well as their interactions, on chickpea growth, yield attributes, and yield, as well as their residual effect on succeeding fodder sorghum.Results indicated that fertilizer levels treatment F3i.e., 100 % RDF (25-50 kg NP ha-1)had significant influence on growth and yield attributing characters like plant height,number of branches plant-1,number of nodules plant-1, number of pods plant-1and also on seed and straw yields of chickpea as compared to treatments F2 (75 % RDF), F1(50 % RDF) and F0 (Control).The residual effect of treatment F3 (100% RDF) had also significantinfluenceon the green fodder yield, dry fodder yield and crude protein content of succeeding fodder sorghum.When compared to B0 (control), the biofertilizers treatment B1 (PSB + Rhizobium @ 5 ml kg-1 seed each) produced significantly higher growth, yield, and yield of chickpea.Application of micronutrients treatment M1(Micronutrient mixture grade-V @ 20 kg ha-1) produced significantly highernumber of branches plant-1, number of nodules plant-1number of pod plant-1, seed yield and straw yield as compared to untreated control (M0).Treatment combination F3B1M1 produced significantly the highest 85 nodules plant-1, number of pods plant-1, seed and straw yields of chickpea, but it was statistically at par with treatment combination F2B1M1 during both the years and on pooled basis.
在2013-14和2014-15两季，在德罗尔阿南农业大学农业研究站进行了田间试验，研究了无机肥、生物肥和微量元素对鹰嘴豆生长、产量属性和产量的影响及其相互作用，以及对后续饲料高粱的残留效应。结果表明:施肥水平处理f3即。与F2 (75% RDF)、F1(50% RDF)和F0(对照)处理相比，100% RDF (25 ~ 50 kg NP hm -1)处理对鹰嘴豆的株高、分枝数、根瘤数、荚果数等生长和产量属性以及种子和秸秆产量有显著影响。F3 (100% RDF)处理的残留效应对后续饲料高粱的青料产量、干料产量和粗蛋白质含量也有显著影响。与B0(对照)相比，生物肥处理B1 (PSB +根瘤菌各5 ml kg-1种子)显著提高了鹰嘴豆的生长、产量和产量。施用微量营养素处理M1(微量营养素混合物等级- v @ 20 kg hm -1)与未经处理的对照(M0)相比，产生了显著更高的分枝植物数量-1，根瘤植物数量-1，荚果植物数量-1，种子产量和秸秆产量。处理组合F3B1M1在鹰嘴豆85根瘤株-1、荚果株-1数、种子和秸秆产量上均显著高于处理组合F2B1M1，但在年份和汇总基础上与处理组合F2B1M1在统计学上相当。
