ThesisItem Open Access STUDIES ON INFLUENCE OF CROPPING SYSTEMS ON SOIL PROPERTIES(CSK HPKV, Palampur, 22-07-19) Dhiman, Shubham; Datt, NaveenA field experiment was conducted during the years 2017-18 at Bhadiarkhar farm, Department of Agronomy, Forages and Grassland Management, CSKHPKV, Palampur to evaluate effect of eight cropping systems viz. rice-wheat, rice-pea-summer squash, okra-radish-onion, turmeric-pea-summer squash, rice-lettuce-potato+coriander, rice-palak-cucumber, rice-broccoli-radish and colocasia-pea+coriander on various soil properties and productivity. The experiment was laid out in randomized block design and was replicated four times. The soil of experiment site was silty clay loam in texture, acidic in reaction (5.3), medium in available nitrogen (362.4 kg ha-1), high in available phosphorus (73.6 kg ha-1) and medium in available potassium (115.2 kg ha-1). Study of one year revealed that rice-pea-summer squash resulted in higher microbial population, microbial biomass carbon and dehydrogenase activity. Higher available K and lower bulk density were recorded in turmeric-pea-summer squash. Colocasia-pea+coriander resulted in higher available N and DTPA-Fe. Better available phosphorus and phosphatase activity were recorded in rice-palak-cucumber. Rice-palak-cucumber cropping system resulted in the highest rice grain equivalent yield (16,477 kg ha-1) compared to the traditional rice-wheat system. Maximum returns (Rs 2,19,828), benefit cost ratio (1.76) and productivity (63.6 kg ha-1 day-1) were also recorded from this system. The yield was significantly and positively correlated with available nitrogen, DTPA-Fe, microbial population, microbial biomass carbon and dehydrogenase activity. Therefore, farmers should substitute existing rice-wheat cropping system with rice-based vegetable systems for improved soil properties, productivity and returns.ThesisItem Open Access EFFECT OF FERTIGATION AND DRIP IRRIGATION ON PRODUCTIVITY OF TOMATO UNDER PROTECTED ENVIRONMENT.(CSK HPKV, Palampur., 2019-07) Singh, Jaspreet; Sandal, Sanjeev K.The present study was conducted at experimental farm of CSKHPKV, Palampur during the year 2018 with the objectives to study the effects of fertigation and drip irrigation schedule on soil, water productivity, crop productivity and NPK uptake. The treatments comprised of two drip irrigation levels DI1 (drip irrigation applied from week 1 to 2 @ 1.0 PE, week 3 to 8 @ 0.4 PE, week 9 to 14 @ 0.6 PE, week 15 to 20 @ 0.8 PE, week 21 to 24 @ 1.0 PE) and DI2 (Drip irrigation applied @ 1.0 PE from week 1 to till harvest) with five nutrient schedules viz., T1 100 % NPK applied through conventional method (C), T2 (C + 100 % N fertigation), T3 (C + 100 % NK fertigation), T4 (C+ 100 % NPK fertigation) and T5 (50 % NPK applied through Conventional method + 150 % through NPK fertigation). The tomato (lycopersicum esculentum) crop was transplanted on April 20, 2018. The results indicated that the soil water content and soil water stock was higher under DI2 and lower under DI1 treatments. The plant height and relative leaf water content (RLWC), biological yield and fruit quality parameter (titrable acidity) and root length were significantly higher under DI2 and lower under DI1 treatments. Among nutrient schedules, plant height, root weight, root length, ascorbic acid, titrable acidity, total soluble solids, biological yield, total NPK uptake were significantly higher under T5 and lower under T1. However, the root volume was significantly higher under T3 and lower in T1. The gross return was highest under T5D2 and lowest under T1D1. The B: C ratio was highest in T3D2 and lowest under T1DI1.The study concluded that the drip irrigation level DI2 (Drip irrigation applied @ 1.0 PE from week 1 to till harvest) and fertigation treatment T5 (50 % NPK through applied conventional method + 150 % through NPK fertigation) were the optimum treatments for obtaining maximum crop productivity.ThesisItem Open Access SULPHUR DYNAMICS AND ITS CRITICAL LIMITS FOR FRENCH BEAN AND CAULIFLOWER IN ACIDIC SOILS OF HIMACHAL PRADESH.(CSKHPKV, Palampur, 2019-07) Gourav; Sankhyan, N. K.Sulphur is best known for its essentiality and vitality in crop production, but due to its widespread deficiency, it is imperative to study its transformations in acidic soils. In the present investigation, 500 soil samples were collected randomly from cultivated acidic soils of Himachal Pradesh, as identified during previous surveys conducted by Department of Soil Science, CSK HPKV Palampur. Processed soil samples were analyzed for pH, soil texture and available sulphur. Five soil profiles were also selected randomly to study the vertical distribution of S. The transformation of sulphur with externally added elemental sulphur was studied in twenty one incubated soil samples, which varied in pH and texture. Further, 10 locations were selectedthat varied in pH, clay content and available S to study the response and to establish critical limits of S for french bean and cauliflower; furthermore the detailed experiment was conductedin pots under glasshouse. In study area, textural class, pH (1:2.5) and available sulphur ranged from loamy sand to clay, 4.23 to 7.00 (extremely acidic to neutral) and 11 to 65 kg ha-1 (deficient to sufficient) respectively. Around 35 per cent of the soil samples were found deficient in available sulphur. Available S exhibited a significant positive correlation with clay and silt, whereas significantnegative correlation was found with sand and pH. All the S fractions (sulphate-S, water soluble-S, heat soluble-S, organic-S and total-S) increased with incubation of soil samples and added elemental S. The highest content of these S fractions were obtained with the application of 80 kg S ha-1. Sole incubation of soil for thirty days without the addition of S, increased all the S fractions except organic-S. Contents of all the S fractions in soils increased with increase in clay and decreased with increase in pH of soil. In soil profiles study, all the S fractions decreased with increase in depth and highest contents of all the S fractions were found in surface layer. Sulphur fractions followed the order as total-S>organic-S>heat soluble-S>sulphate-S>water soluble-S. French bean and cauliflower responded significantly to the S application. Highest yield and yield attributes were obtained with the application of 40 kg S ha-1 in both the crops. However, the green pod yield in french bean at 30 kg S ha-1 was statistically at par with 40 kg S ha-1. Critical limits for french bean and cauliflower in soil were found to be 9.5 mg kg-1 and 10.5 mg kg-1, respectively. Whereas, the critical limits for french bean and cauliflower in plantswere found to be 0.103 per cent and 0.337 per cent sulphur, respectively.ThesisItem Open Access EFFECT OF FERTIGATION AND DRIP IRRIGATION ON PRODUCTIVITY OF TOMATO UNDER PROTECTED ENVIRONMENT(CSKHPKV, Palampur, 2019-07) Singh, Jaspreet; Sandal, Sanjeev K.The present study was conducted at experimental farm of CSKHPKV, Palampur during the year 2018 with the objectives to study the effects of fertigation and drip irrigation schedule on soil, water productivity, crop productivity and NPK uptake.

K.The unique geographical position and special climate environment have attracted more and more tourists to Himachal Pradesh and consequently, affecting the environment gradually by vehicular exhaust because environment in this state is rarely affected by other anthropogenic activities. The present study entitled “Studies on heavy metals contamination along national highway soils and plants ecosystem in Himachal Pradesh” was therefore, designed to assess the extent of heavy metals concentration in roadside soils and plants along NH-21 and to characterize soil and plant samples into safe/toxic levels. The selected study sites of current study were Dadour, Nagchala, Takoli, Nagwain and Jhiri in Mandi district and Kais, Kararsu, Raison, Katrain and Patlikuhal in Kullu district. One rural road in each district was also taken as a background sampling site (Rahala in Mandi and Dobhi in Kullu) to compare the extent of heavy metals with that of NH-21. Soil and fruit samples of commercially grown tomato and apple were collected at 0 m, 50 m, 100 m, 200 m, 300 m, 400 m and 500 m on both sides of NH-21. The sampling was done during peak tourist season starting from first week of May, 2018 till last week of July 2018. Surface soil samples collected at above mentioned sites were processed, digested and analyzed for heavy metals following standard methods. Similarly, fruit samples of tomato from each site in Mandi district and apple fruits in Kullu district were processed, digested and analyzed for heavy metals using standard techniques. Means were used to assess the contamination levels of heavy metals in soil and fruit samples at each site and comparison was done with maximum permissible limits set by WHO/FAO. Correlation carried out to determine the relationships between sampling locations from road and soil properties and heavy metal in both soil and edible plant parts. The results of current study revealed that samples taken next to the road were characterized by higher values of soil pH, EC and heavy metals in soil as well as in tomato and apple fruits. Decreased values of measured variables in soils and plant were recorded along with an increase in the distance from the national highway. The concentration of heavy metals were in sequence Fe > Mn > Zn > Cu > Pb > Cr > As > Hg for soil and Mn > Zn > Cu > Fe >Pb > As > Cr > Hg for plant. However, Hg in soil was detected only at Dadour and Nagchala sampling sites in Mandi, whereas it was below the detection limit in other sampling sites of Mandi and Kullu district. The roadside surface soil as well as tomato and apple fruit samples were relatively contaminated with heavy metals. The results of this study revealed elevated values of heavy metals e.g. Fe, Zn, Pb and As in soil and Cu, Zn, Pb and As in plant. On the other hand, Cu, Mn, Cr and Hg in soil and Fe, Mn, Cr and Hg in plant were below the maximum permissible limits as set by WHO/FAO. The results of correlation analysis between the levels of the heavy metals and varying sampling distances from road along two sides (left and right) from each of the sampling sites revealed a significant (p ≤ 0.01) but negative correlation. The observed negative correlation values depicted that concentration of heavy metals in soil and plant decreased with increase in sampling distances from the road. These heavy metals are cumulative poisons and their values need to be below the proposed maximum tolerable levels fixed by the FAO/WHO. It is therefore, recommended that the levels of heavy metals in soils and plants should be constantly monitored.ThesisItem Open Access LONG TERM EFFECT OF PRESCRIPTION BASED FERTILIZER APPLICATION ON ZINC FRACTIONS IN SOIL.(CSKHPKV, Palampur, 22-06-19) Choudhary, Deeksha; Dixit, S.
