The genetic analysis of pea (Pisum sativum L.) was carried out twenty five germplasm lines under irrigated normal soil condition to determine mode of inheritance of yield and its contributing traits. The experiment was conducted to evaluate in Randomized Block Design (RBD) with three replication at Nidharia Agriculture Farm S.M.M.Town P.G. College, Ballia, U.P. The data was recorded on twelve characters viz, such as days to 50% germination, days to 50% flowering, plant height, days to maturity, pod length, branches per plant, number of pods per plant, number of seed per plant, biological yield per plant, test weight, harvest index and seed yield per plant. The variation in treatment for all characters was found significant for all the characters. All the 25 genotypes showed vast range of variation for all the 12 characters under consideration. Genotypes such as 725-D, 940-D and ARPANA produced the highest seed yield and several out-yielder genotypes are also observed. The highest amount of genotypic and phenotypic coefficient of variations were observed for plant height, number of pods per plant and seed yield per plant. The maximum value of heritability (99) was reported for plant height and minimum value of heritability (29) was reported for the pod length while remaining characters expressed the heritability in decreasing order such as pods per plant (97) , biological yield per plant (97), seed yield per plant (94), number of branches per plant (85), days to 50% germination (84), harvest index (80), days to 50% flowering (79), test weight (69), days to maturity (64) and number of seed per pod (94). The maximum value of genetic advance in percent of mean was found for the plant height (86.63) and minimum value was found for the days to maturity (3.889).The result revealed that these traits may serve as effective selection attributes during selection in breeding program for yield improvement.

The project was undertaken to study the roleof phenol against MYMV resistance in mungbean plants in natural condition.The present investigation was undertaken during the spring season at Research Farm of Tirhut College of Agriculture, Dholi, Muzaffarpur, Bihar. Four genotypes of mungbean namely HUM-16,TMV-37, Samrat and LGG 450 has been taken. The estimation of total phenol content protocol was carried out with Folin-Ciocalteu Reagent (FCR) by Bray and Thorpe 1954. The absorbance at 650 nm at 1mg/g concentration of phenol was found to be 0.727 a.u. This value was taken as standard as it is very close to the mean value. Highest value of absorbance at 650 nm was found in TMV 37, followed by HUM 16 and Samrat respectively. LGG 450 showed the least value of absorbance which was in direct correlation with MYMV resistance.

Fruit production contributes significantly to food security and economic empowerment in Uttar Pradesh State of India. To ensure sustainable economic contribution of the commodities, understanding the growth and instability trends in crop area and production is imperative. The study analyzed growth and instability in area and production of mango and guava in the State. Time series data from 2005-06 to 2020-21 of the of mango and guava crops area and production of U.P. State were analyzed using semi log function. Result of the growth analysis indicated that growth rate of area and production of mango and guava were positive. The mango and guava fruits crop area and production data were analyzed to determine the instability and growth rates in area and production of these two fruit crops of Uttar Pradesh State covering the most recent period from 2005-06 to 2020-21 by using coefficient of variance (CV) compound growth rates (CGR). It was found that mango registered variability of 3.67% and 18.98%, and compound growth rates of 0.55% and 4.16% in crop area and production, respectively during 16 years period (2005-06 to 2020-21). Similarly, guava registered variability of 62.36% and 6.16%, and compound growth rates of 15.13% and 18.86% in crop area and production, respectively during 16 years period (2005-06 to 2020-21). It is found that growth rates in crop area of mango and guava are lower than growth rate of production in these two crops. This indicates that area has marginal impact on production of these two crops; however, technological interventions such as improved varieties, integrated nutrient and water management, canopy management, integrated pest management, etc., might have more impact on fruit product. This type of study is useful for policy makers/ government in improving fruit production.

India is the world's largest operator and manufacturer of agricultural tractors. The ergonomic concerns and incorporating the physical and strength capabilities of the Indian operators were neglected while designing and developing the tractors in India. As a result, there was a substantial mismatch between the operators' capabilities and the forces required to operate the tractors' controls. Therefore, this study was planned to determine the actuation forces of frequently operated controls on popular Indian tractors. Ten agricultural tractors of different makes and models in the power range of 23 to 50 kW were selected for the study. The Sushma steering torque measurement system, Novatech pedal force loadcell, and Gear effort transducer were used to measure the actuation force of the controls, steering wheel, clutch and brake pedal, and gear shifter lever, respectively. The actuation forces required to operate the clutch pedal on selected tractors ranged from 130 to 250 N, well below the IS 10703 (1992) limit of 350 N. Except for one tractor, the brake pedal actuation forces observed for the selected tractors varied from 390 to 670 N, well below the recommended limit of 600 N given by IS 10703 (1992). In static conditions, most tractors' steering wheel actuation forces ranged from 210 to 340 N, exceeding or approaching the 250 N limit set by AIS-042 (2004). In dynamic conditions, when tractors were operated at 3 km/h, the actuating forces for the selected tractors ranged from 90-220 N and were well within the AIS-042 limit.

Oyster mushroom (Pleurotus sp) belonging to class Basidiomycetes and Family Agaricaceae is popularly known as ‘dhingri’ in India. It constitutes thirty percent of total production and ranks third among the cultivated mushrooms grown widely in temperate, tropical and subtropical regions of the world. Hypsizygus ulmarius is an edible mushroom, also known as elm oyster mushroom or blue oyster mushroom. It was introduced for commercial production for the first time in India by IIHR. The present investigation was undertaken during 2018-19 to evaluate the growth behavior and yield of blue oyster mushroom on the basis of various spawn as well as bed substrates. Among all the five grains tested, sorghum grain required the least days (14.50 days) for spawn run and mycelium is tightly attached with grains. Sorghum grain was considered as best treatment also in the context of yield and biological efficiency of 1539.50g/bed and 76.98% respectively. Among five different substrates, sugarcane bagasse took minimum time for spawn run (16.50 days)which significantly differs from other substrates and maximum time required for spawn run was observed in groundnut hulls (23.75 days). Minimum time required for pinhead emergence was in maize stalk (8.25 days). Paddy straw substrate gave the highest yield (1552.00g) as well as highest biological efficiency of 77.60%.

Climate change is one of the most important worldwide issues talked among the scientists and researchers. The temperature and rainfall trends are analyzed for meteorological data of Junagadh station in Gujarat. India over approximately last three decades stretching between years 1971 to 2013. The long–term change in temperature and rainfall has been assessed by linear trend analysis. The increasing trend in mean monthly maximum temperature (MMAX) and total mean rainfall (TMRF) is confirmed by Mann-Kendall trend test. It is evident from that monthly mean temperature have increased significantly for all the months except the months of April and October for which a very weak decrease in mean maximum temperature is observed. This implies that at Junagadh, the highest increase in temperature occurred in November (0.0210C) during 1980-2011 period. The annual mean of monthly maximum temperatures (MMAX) observed an increasing trend having an annual decreasing of 0.0040C year during 1980-2011. It is evident TMRF have increased for the months April, May August and September whereas it shows decreasing trend in January, Feb, March, June, July, October, November and December. This implies that at Junagadh, the highest increase in TMRF occurs in August and increased by (0.029 mm) during the last 1980-2011. The highest decrease in TMRF occurs in June and decreased by (2.153mm) during the same period. The annual mean of total monthly rainfall observed a decreasing trend having an decrease of 0.249 mm/year during the last 31 years.

A study was conducted to estimate the effect of potassium and KSB on the growth and yield of lentil at SKUAST-K during rabi 2019 and 2020. The experiment was laid out in randomized complete block design with eight treatments (Control, 10 kg K/ha, 20 kg K/ha, 30 kg K/ha, KSB, 10 kg K/ha + KSB, 20 kg K/ha + KSB and 30 kg K/ha + KSB) replicated thrice. Application of potassium alone or in combination with KSB had a significant effect on growth and yield of lentil. The combined application of 30 kg K/ha + KSB recorded highest the plant height (28.55 cm), pods per plant (49.93) and seeds per pod (1.87) but statistically at par with application of potassium at 30 kg/ha alone. The lowest value of growth and yield attributes was recorded in control treatment. The highest grain yield of 6.81 q/ha was observed with combined application of 30 kg K/ha + KSB which was at par with potassium application @ 30 kg/ha alone with the lowest yield recorded in control treatment. The experiment indicated that potassium application alone or in combination was found to have a significant impact on lentil growth and yield.

The experiment indicated that potassium application alone or in combination was found to have a significant impact on lentil growth and yield.","PeriodicalId":14972,"journal":{"name":"Journal of AgriSearch","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-03-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"78173364","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}

In direct seeded rice, weeds are the major problems limiting the crop productivity. Sesbania with direct seeded rice (DSR) as well as seeding rates of rice affects the weed density by smothering effect and therefore, it can be a better weed management practice. Two year on farm trials were conducted at the Kusma, Boarijore Block and Bhaluka, Sundarpahadi block of Godda from 2020 and 2021 to assess the effect of weed management on yields and economics in DSR. The results revealed that significantly the lowest density of grasses, broad leaved weeds (BLWs), sedges, total weed density, total weed dry weight and the highest weed control efficiency were recorded with the treatment of DSR + Sesbania over DSR (pre-sowing irrigation followed by tillage and rice seeding) followed by first post-sowing irrigation at 15 DAS and the farmer’s practice. Weed management practice, DSR + Sesbania was found significantly higher grain yield, gross returns, net returns, B: C ratio, production efficiency and economic efficiency over to followed by first post sowing irrigation at 15 DAS and farmer’s practice. While the farmer’s practice was recorded higher weed index and lowest weed control efficiency. Thus, on the basis present study it is concluded that weed management practice i.e. DSR + Sesbania could be a better option to reduced the weed infestation as well as improves the productivity of DSR in rainfed agro-ecosystem of Jharkhand.

The research was carried outto assess the readiness of farmers toward crop residual management. For this study, Karnal, Kurukshetra, and Fatehabad districts were selected purposively according to the report of Haryana Space Applications Center (2018). The total number of the respondent understudy was 180. Data regarding socio-economic status, assets availability, source of information, and readiness of farmers were collected with the help of a structured interview schedule because some driving factors may affect the readiness of the farmer. A positive and significant relationship was found at a 0.01% level of Significantbetween the readiness of the respondents and operational land holding, annual income, farm assets, and source of information and with education at a 0.05% level of significance. So,making farmers aware of available management alternatives using the different extension and educational programs and by providing financial and technical backup it may reduce the rate of residue burning and increase the rate of adoption of management practices.
