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 SOIL HEALTH ASSESSMENT IN TEA GARDENS OF HIMACHAL PRADESH.(CSKHPKV, Palampur, 2019-07) Gill, Ankit; Sharma, V.K.The soiill healltth assessmentt proviides an iinsiightt iintto soiill-rellatted consttraiintts and pottenttiialls for susttaiinablle agriiculltturall pllanniing..

UNDER CONSERVATION TILLAGE(CSKHPKV, Palampur, 2019-06) Bijani, Hemali; Sharma, Sanjay K.The present study was conducted at experimental farm of CSK HPKV, Palampur, during the year 2017-18 with the objectives to evaluating the effect of irrigation levels and nutrient management on yield and nutrient uptake by gobhi sarson (Brassica napus L.) under conservation tillage and to study the effect of various treatments on soil properties. Twelve treatments comprised three irrigation levels viz., I1 (no irrigation), I2 (50% i.e. 25 mm irrigation at critical stages) and I3 (100% i.e. 50 mm irrigation at critical stages) in main plots and four nutrient management (NM) levels viz., NM1 (FYM @ 25 t ha-1), NM2 (FYM @ 20 t ha-1 + 50%NPK), NM3 (FYM @ 10 t ha-1 + 75%NPK) and NM4 (100%NPK) in sub plots were evaluated in a split plot design. Gobhi sarson (var. GSC-7) was sown on 24 November 2017. Irrigation with 25 mm water (I2) at 40 DAS (vegetative growth stage) and 130 DAS (siliqua development stage) improved the plant height (cm) and no. of primary and secondary branches, no. of siliquae per plant, no. of seeds per siliqua of crop and finally enhanced the yield of crop significantly in comparison to rainfed conditions (I1). Further increase in irrigation level to I3 at the respective irrigation stages, however, did not enhance the yield. Among nutrient management practices significantly better growth and yield attributes were observed under INM treatment involving NM3 which resulted in significantly highest seed yield (13.50 q ha-1) followed by NM2 and NM4. The minimum growth and seed yield (10.27 q ha-1) of crop was observed in the plots receiving 25 t ha-1 FYM only. Effects of irrigation and nutrient management levels on 1000-seed weight and harvest index were not significant. The uptake of different nutrients viz; N, P, K, S, Fe, Mn, Cu and Zn by gobhi sarson in general, followed the yield trend. Crude protein content (15.63%) were higher under I3 level of irrigation and NM3 level of nutrient management (15.38%). Soil pH and organic carbon at surface (0-0.15 m) and sub-surface (0.15-0.30 m) layers were not affected by irrigation as well as nutrient management levels. Water holding capacity and available N, P, K, S and micronutrient cations (Fe, Mn, Cu and Zn) in soil increased significantly by integrated nutrient management levels over sole chemical and organic application but irrigation levels did not bring significant change in their contents. Total water use efficiency (TWUE) was not affected by irrigation levels but nutrient management levels had significant influence on it. Irrigation water use efficiency (IWUE) decreased with increase in irrigation levels, whereas among nutrient management levels integrated plots increased it. The highest gross return (Rs. 66,063 ha-1) and net return (Rs. 33,407 ha-1) were obtained under combination I3NM3 whereas highest B: C ratio obtained with combination of I2NM4 (2.47).ThesisItem Open Access EFFECT OF CROPPING SYSTEMS AND NUTRIENT MANAGEMENT PRACTICES ON YIELD AND SOIL PROPERTIES UNDER MID-HILLS OF HIMACHAL PRADESH(CSKHPKV, Palampur, 2017-09) Kumawat, Utkarsh; Parmar, D. K.Long-term experiments on nutrient management in cropping systems can be more useful for studying the changes in soil properties and processes over time and for obtaining information on sustainability of agricultural systems for developing future strategies to maintain soil health. The current study on “Effect of cropping systems and nutrient management practices on yield and soil properties under mid-hills of Himachal Pradesh” was carried out at the experimental farm of Himachal Pradesh Krishi Vishvavidyalaya, Hill Agricultural Research and Extension Centre, Bajaura, Kullu (India). This study is a part of ICAR-Network Project on Organic Farming which was initiated in 2004. The experiment had four cropping systems (tomato-cauliflower-frenchbean; tomato-cauliflower; black gram-cauliflower-squash and okra-garden pea) and three nutrient management practices (organic; inorganic and integrated), which were evaluated in a split plot design. The sowing/transplanting schedule for different crops selected for study was followed as per state package of practices. Triplicate soil samples from three soil depths (0-0.15, 0.15-0.30 and 0.30-0.45 m) collected at the initiation of trial in 2004 and after 11th cropping cycles during 2016, were analyzed for soil physical, chemical and microbiological properties following standard procedures. The yield of crops was recorded and sum up after final picking/harvesting and expressed in q ha-1. The total system productivity was calculated by summing up the yield of each crop. The economic analysis of different experimental treatments was carried out, taking into consideration the prevailing market prices of inputs used. The results indicated that regular addition of organic amendments increased some soil chemical properties like organic carbon and availability of micronutrients besides, soil physical fertility, mainly by decreasing soil bulk density. However, other characteristics such as soil pH and availability of major and micronutrients was the maximum for integrated practice of nutrient management. Cropping systems increased organic carbon and status of major and secondary nutrients, whereas soil pH and concentration of micronutrients was not influenced among variable cropping systems. The results showed that continuous long-term use of organic manures increased soil organic carbon stock, carbon sequestration and its rate in comparison to fertilizer alone or combination of both. The intensive cropping recorded higher value of these parameters as compared to less intensive cropping. The growth of soil microorganisms (bacteria, fungi, actinomycetes), total microbial biomass carbon and enzyme activity increased due to organic amendments for 11 years; however cropping systems had no effect of growth of such organisms. The combined application of organic and fertilizers (50:50) gave maximum yield and profit for black gram-cauliflower-squash crop rotation as compared to other practices and crop rotations. However, benefit cost ratio was the maximum for tomato-cauliflower system.ThesisItem Open Access STUDIES ON PERFORMANCE OF IMPROVED GRASSES ON DEGRADED GRASSLAND UNDER MID HILL CONDITIONS OF H.P.(CSKHPKV, Palampur, 2018-08) Shalley; Rameshwar KumarA field experiment was conducted during July 2016 to October 2017 at Agroforestry Farm of Department of Horticulture and Agroforestry, CSK HPKV, Palampur to study the performance of improved grasses on degraded grassland under mid hill conditions of H.P. The experiment consisted of 7 treatments comprising of Setaria, Brachiaria, White clover and their 3 combinations viz; Setaria+White clover, Brachiaria+White clover, Setaria+ Brachiaria+White clover and control. The experiment was laid out in Randomized Block Design with three replications. The soil of the experimental site was sandy clay loam in texture and acidic in reaction. It was rated as medium in organic carbon, available nitrogen, available phosphorus and available potassium. Observations were recorded on various growth and development, yield, quality, soil and economy parameters. Setaria+White clover treatment proved to be the best combination as it recorded significantly highest green (27.11 t ha-1) and dry fodder yield (4.98 t ha-1). Productive potential of the degraded grassland increased 3.2, 2.7 and 2.5 times by the introduction of improved grasses Setaria+ White clover, Setaria and Setaria+Brachiaria+White clover respectively. Fodder was analyzed for various quality parameters at the time of different cuts of forages. Most of the parameters were higher in pure Setaria as compared to other grasses like dry matter content (19.24%), ADF (47.68%), oxalate (3.18%) and lignin (6.56%) while NDF (67.20%) and ash (9.80 %) were higher in pure Brachiaria grass. White clover when grown pure had highest crude protein content (20%). Setaria grass when mixed with White clover had higher crude protein yield 6.31 q ha-1 than all other combinations of grasses. Higher net return of Rs. 11,175.8 ha-1 was obtained in Setaria and White clover. B:C ratio was higher in White clover (0.42) than all other treatments of forage species. Minimum B:C ratio was obtained in Setaria+Brachiaria+White clover because of high cost of rootslips.
