    Identification and Characterization of Genes Responsible for Root Development during Drought Stress in Tumba (Citrullus colocynthis)
    (College of Agriculture, Swami Keshwanand Rajasthan Agricultural University, 2022) MAHAVEER PRASAD CHOUDHARY; Dr. Chet Ram
    The cucurbit family is a large family with several economicallyimportant species such as watermelon (Citrullus lanatus var. lanatus),melon (Cucumis melo), cucumber (C. sativus), several cucurbit speciesalong with their wild relatives, etc. Tumba [Citrullus colocynthis (L.)Schrad (2n= 2x= 22)] also known as the bitter apple, closely relatedwild species to domesticated watermelon (C. lanatus var. lanatus), is averydroughttolerantperennialherbaceousspeciesintheCucurbitaceae family. It can survive in arid environments bymaintaining its water content in the root system under severe stressconditions (Si et al., 2009). Tumba is also used as important medicinalplant to cure several diseases in animals by its laxative effects. Tumbais a rich source of oil which is used for many medicinal and industrialpurposes. Tumba has mild diuretic, bitter tonic, stomachic, andantilithic properties (Hussain et al., 2014, Li et al., 2021). It iscategorized as Tikta-rasam, ushna-veeryam and katuvipakam in theHerbal remedies and Siddha medical traditions and is used as apurgative, diuretic, laxative, kapharam and abortifacient. Fruit is usedto treat tumours, leucoderma, ulcers, asthma and other diseases. It isbitter and pungent and acts as a purgative, anthelmintic, antipyreticand carminative. Root is beneficial for rheumatism, ascites, urinaryinfection and jaundice (Pravin et al., 2013; Kapoor et al., 2020). Theseeds of Tumba were found in several early Egyptian, Libyan and NearEastern sites from about 4000 BC. This species grows in sandy areasthroughout northern Africa, south-western Asia and the Mediterraneanregion of the world. The species has been used as a model to exposethe function of genes implicated in the stress response which ultimatelymay lead to enhancement of stress tolerance in cucurbit crops throughgenetic manipulation.

    Effect of NPK on Growth, Yield and Quality of Garden Pea [Pisum sativuativum (L.)] in Western Rajasthan
    (College of Agriculture, Swami Keshwanand Rajasthan Agricultural University, 2020) LOKESH KUMAR; Susheel Kumar
    Garden Pea [ Pisum sativum (L.)] is an important crop grown all over the world. In India, garden pea is mainly grown as winter vegetable in the plains of North India and as summer vegetable in the hills. Peas are used primarily as a vegetable and consumed as pulses. It is utilized as fresh vegetable, canned, processed or dehydrated (Thamburaj and Singh, 2005). Pea belongs to family Leguminosae. It is annual herbaceous plant as dwarf as 20 cm and as tall as 1 to 1.25 meter or more. It is a self-pollinated crop, fruit which is eaten, known as pod. It is thought to have originated in the Ethiopia, part of Europe and Asia (Choudhary, 1967 a). Pea occupies an area of 540 thousand hectares with the production of 5422 thousand tonnes in India (Anonymous, 2017-18). It is cultivated in Rajasthan on about 14500 hectares area with an annual production of 32000 MT (Anonymous, 2017). It is largely cultivated in Jaipur, Baran, Bundi, Kota and Bharatpur districts of Rajasthan. The average production of pea is 70-80 q green pods ha -1 with a shelling percentage of 30-35 (Fageria, 2003).

    Effect of Canal Silt and Compost as Soil amendments and Fertilizers on Soil Properties and Onion Seed Production in Torripsamment
    (COLLEGE OF AGRICULTURE SWAMI KESHWANAND RAJASTHAN AGRICULTURAL UNIVERSITY, BIKANER, 2022) SUMITRA KUMAWAT; S. R. Yadav
    The recognition of the fact that a nation's and the world's soil resources are limited and basically irreplaceable has in recent years caused considerable discussion. Calculations of population growth, of areas available for more intensive use and of areas being lost from agricultural production through land degradation and desertification, have highlighted the urgent need for development of technologies for improving the productivity of sandy soils. These soils are of wide occurrence in arid and semi-arid regions all over the world. The Indian or the Thar desert has an area of 317000 km 2 spread over four states the Punjab, Haryana, Rajasthan and Gujarat. of the total area, 61 per cent is in Rajasthan. Two-third soils of Rajasthan, occurring in the arid and semi-arid regions are loamy sand to sand in texture. The major limitation of such soils is their low moisture retentive capacity requiring frequent irrigation for successful crop production. High infiltration capacity coupled with high hydraulic conductivity invariably results in large quantities of water loss by deep percolation besides leaching of soluble nutrients beyond root zone (Mann and Singh, 1975).

    Characterization of Underground Irrigation Water Quality and its Effect on Soil Properties of Marwar Junction and Rani Tehsils of Pali, Rajasthan
    (COLLEGE OF AGRICULTURE SWAMI KESHWANAND RAJASTHAN AGRICULTURAL UNIVERSITY, BIKANER, 2021) SUMAN DHAKA; Ranjeet Singh
    Agriculture is the backbone of Indian economy. Presently, it provides livelihood to about 58 per cent of the Indian labour force and contributes 14 per cent in GDP of the Indian Nation (Anon., 2021). India is having a huge diversity in the biogeography across the country. Among Indian states, Rajasthan is also having a large diversity in soil, climate and water resources. This diversity is given an opportunity to grow a large number of agricultural crops. But, the quality and quantity of water required for obtaining the high quality production of agricultural crops. Even more, the Rajasthan state is also privileged to natural abiotic stresses such as drought, salinity, frost, heat shocks and nutritional deficiency which also affect the crop productivity, quality and its sustainability.

    Management and Physiological Studies on Alternaria Leaf Spot of Mustard Incited by Alternaria brassicae (Berk.) Sacc.
    (College of Agriculture, Swami Keshwanand Rajasthan Agricultural University, 2021) JASVEER SINGH; Data Ram Kumhar
    Mustard crop play an important role in agricultural economy of India. Oilseed brassicas also called rapeseed-mustard placed in family brassicaceae. Brassicaceae family contains about 3500 species and 350 genera. This family is one of the most economically important plant families. According to ancient scripture and literature, mustard has been cultivated from 5000 BC (Kumar et al., 2014). Rapeseed-mustard group of crops is the third most important oil seed crop group in terms of area and production after soybean and palm in the world and in India it occupy second position after groundnut (Kumar and Chopra, 2014).

    Growth rate and crop Diversification towards High Value Crops in Haryana.
    (College of Agriculture, Swami Keshwanand Rajasthan Agricultural University, 2019) Harshit Bansal; Shirish Sharma
    Diversification is an important part of the changing economy. Conceptually the term "diversification" has been derived from the word "diverge" which means to move or extend in the direction different from a common point Jha et al., 2009. In Agriculture, diversification can be defined as shift from the regional dominance of one crop like rice to another crop like oilseeds, or from one enterprise to another enterprise or to engage in other complimentary activities. Agriculture diversification from the theoretical point of view may be considered as diversification of resources from low income generating crops to high income generating crops. In developing countries like india starts with a gradual shift towards diversification.

    (College of Agriculture, Swami Keshwanand Rajasthan Agricultural University, 2022) DHARMPAL; S. K. Yadav
    Indian mustard, Brassica juncea (L.) Czern and Coss is one of the important oilseed crops cultivated all over India and world also and its oil constitute important component of human diet. The oilseed crops play an important role in Indian economy. When compared to other edible oils, the rapeseed-mustard oil has the lowest amount of harmful saturated fatty acids. Rajasthan, Gujarat, Madhya Pradesh, Uttar Pradesh, West Bengal and Assam are the leading states in production of rapeseed-mustard. Amongst important annual oilseed crops grown in the country, rapeseed and mustard occupy the second place in terms of average production after groundnut. It is grown over an area of 6.86 million hectares with production of 9.12 million tonnes (Anonymous 2021). In Rajasthan, the area under this crop was 3.07 million hectares with average production of 4.02 million tonnes (Anonymous, 2021). The main mustard growing districts of Rajasthan are Bharatpur, Alwar, Sawai Madhopur, Sri Ganganagar and Jaipur.

    APPRAISAL OF GROUND WATER QUALITY AND ITS EFFECT ON SOIL PROPERTIES OF DHORIMANA AND GUDHAMALANI TEHSILS OF BARMER DISTRICT OF RAJASTHAN
    (COLLEGE OF AGRICULTURE, SWAMI KESHWANAND RAJASTHAN AGRICULTURAL UNIVERSITY, 2022) BANKA RAM; R. K. Jakhar
    Agriculture is one of the unavoidable man made activities on the earth, which is utilizing a huge million cubics of ground water for the growth and yield of plants (Khan et al., 2020). Ground water is an indispensable renewable resource found on earth, significant for supporting habitat, maintaining hydrological balance as well as sustaining human needs. Ground water is the major source of irrigation in most of the arid and semi-arid regions of the country. The hot and dry climates of these regions require irrigation water which does not contain soluble salt in the amounts which have adverse effects on the soil and crops. In the present assessment, the total annual ground water recharge in the country has been assessed as 436.15 billion cubic meters. Keeping an allocation for natural discharge, the annual extractable ground water resource has been assessed as 397.62 billion cubic meters. Annual ground water extraction for irrigation, domestic and industrial uses is 244.92 billion cubic meters. The average stage of ground water extraction for the country as a whole works out to be about 61.6 per cent (CGWB, 2020).
