ThesisItem Open Access Challenges and Opportunities for Small and Marginal Farmers in Jaipur District: An Economic Analysis (SKNAU)(SKNAU, 2020) Jat, Mohan LalThesisItem Open Access Effect of pre-harvest fruit bagging on maturity and physico-chemical properties of guava fruits cv. VNR Bihi(G.B. Pant University of Agriculture and Technology, Pantnagar - 263145 (Uttarakhand), 2019-06) Jat, Mohan Lal; Tripathi, ShaileshThe present experiment was conducted at Horticulture Research Centre, Pattarchatta and Department of Horticulture, G. B. Pant University of Agriculture & Technology, Pantnagar, Udam Singh Nagar, Uttarakhand, during the year 2018-2019. To evaluate the effect of different pre-harvest bagging materials (Biodegradable bags; purple, yellow, pink, green and red; Polypropylene bags; blue, light green, white, green and red; Polyethylene bags; yellow, white, blue, green, orange and pink) on maturity and physico-chemical properties of guava cv. VNR Bihi. Altogether, there were seventeen treatments replicated five times. The bagging was done 6 weeks before harvest. Among the various bagging materials used; blue polyethylene bag was found superior for the physical characteristics of guava fruits viz., fruit length, fruit diameter, fruit weight, fruit volume, specific gravity, fruit firmness and flesh thickness while, pink biodegradable bag was found to improve chemical characteristics viz., total soluble solids, titratable acidity, TSS:acid ratio, ascorbic acid, total sugars, reducing sugars, non-reducing sugars content significantly with 10 days earlier fruit maturity compared to unbagged fruits. Based on the overall findings, it could be concluded that fruit bagging is highly beneficial for the quality improvement of guava fruits cv. VNR Bihi. As per the results, pre-harvest fruit bagging with blue polyethylene or pink biodegradable bags were found the best for the improvement of physical and chemical quality parameters of the fruits. So, it can be conferred that farmers should use pre-harvest fruit bagging so that quality fruit production of guava can be achieved for better economic returns.ThesisItem Open Access Integrated Nutrient Management in Barley (Hordeum vulgare L.)(MPUAT, Udaipur, 2021) Jat, Mohan Lal; Chaplot, P. C.A field experiment entitled “Integrated Nutrient Management in Barley (Hordeum vulgare L.)” was conducted on clay loam soil having low in available nitrogen (287.60 to 288.30 kg ha-1), medium in available phosphorus (18.80 to 20.50 kg ha-1) and high in available potassium status (338.70 to 346.40 kg ha-1) with slightly alkaline in reaction at the Instructional Farm, Department of Agronomy, Rajasthan College of Agriculture, MPUAT, Udaipur during the rabi season 2017-18 and 2018- 19 with the objective to evaluate the effect of integrated nutrient management on productivity of barley. The experiment was laid out in randomized block design (Factorial) with comprised combinations of six fertility levels and four liquid bio inoculants. The barley crop fertilized with 125% RDF in conjunction with 5 t FYM ha-1 significantly enhanced plant height, dry matter accumulation at successive growth stages, dry matter partitioning at harvest, number of tillers, chlorophyll content and growth efficiency which was found at par with application of 100% RDF + 5 t FYM ha-1 (except plant height) over rest of fertility levels during both years. These improvement manifested in the production of higher effective tillers, ear length, ear weight, grains ear-1, grain weight ear-1, straw weight ear-1, filled spikelet ear-1 and test weight with the concomitant increase in productivity in terms of grain, straw and biological yield. The magnitude of increase was to the tune of 42.46, 27.49, 32.95 and 38.90, 26.18, 30.80 per cent, respectively over the application of 75% RDF. Highest N, P and K concentration and accumulation also recorded under both these treatments in grain and straw thereby total uptake. Both 125% RDF + 5 t FYM ha-1 and 100% RDF + 5 t FYM ha-1 fetched net return of ` 66492 and 64933 with B-C ratio 2.15 and 2.14. The results showed that seed treatment with liquid bio-inoculants Azotobactor + Azospirillum + Phosphates solubilizer + PGPR significantly improved growth parameters viz., plant height, dry matter accumulation at successive growth stages, total tillers, chlorophyll content, growth efficiency and yield attributes viz., effective tillers, ear length, ear weight, grains ear-1, grain weight ear-1, straw weight ear-1, filled spikelet ear-1 and test weight thereby grain, straw and biological yield of barley crop which was found at par with inoculation of Azotobactor + PSB over inoculation of Azotobactor and PSB alone during both the years of investigation. Seed inoculation with liquid bio-inoculant Azotobactor + Azospirillum + Phosphates solubilizer + PGPR significantly improved grain, straw and biological yield to the extent of 28.96, 25.70, 11.32, 7.50 and 17.82, 14.20 per cent, respectively over inoculation of Azotobactor and PSB alone. The corresponding increase in grain, straw and biological yield with seed inoculation by liquid bio-inoculants Azotobactor + PSB was 34.73, 31.32, 15.22, 11.26 and 22.37, 18.61 per cent. Further seed inoculation of barley with liquid bio fertilizer consisted combination of Azotobactor + Azospirillum + Phosphates solubilizer + PGPR recorded maximum N, P and K concentration and accumulation in grain and straw thereby total uptake which was found at par with Azotobactor + PSB inoculation over inoculation of Azotobactor and PSB alone during both years. Inoculation of barley seed with liquid bio-inoculant consisting combination of Azotobactor + Azospirillum + Phosphates solubilizer + PGPR recorded maximum net return (` 67906) and B-C ratio 2.44 closely followed by seed inoculation with liquid bio-inoculant Azotobactor + PSB with net return (` 65006) and B-C ratio 2.31 registering significantly higher over inoculation with Azotobactor and PSB alone.ThesisItem Open Access Micro-irrigation Management in Fennel (Foeniculum vulgare Mill.)(SKNAU)(SKNAU, 2013) Jat, Mohan LalThesisItem Open Access Prediction Of Drought Under Different Agro-Climatic Zones Of Rajasthan(Maharana Pratap University of Agriculture and Technology ;Udaipur, 2001) Jat, Mohan Lal; Singh, Raj Vir
