ThesisItem Open Access EFFECT OF DRIP IRRIGATION ON SOIL-PLANT WATER DYNAMICS, NUTRIENT USE AND PRODUCTIVITY OF CAPSICUM AND BROCCOLI UNDER VARYING NPK FERTIGATION IN AN ACID ALFISOL(CSK,HPKV,PALAMPUR, 2016-04) Kapoor, Renu; Sandal, Sanjeev.K.ABSTRACT In Hilly areas, the judicious use of the available water resources through drip irrigation under open and protected conditions becomes necessary to enhance the yield, nutrient and water use efficiency. Field experiments were conducted during 2013-14 and 2014-15 at experimental farm, CSK HPKV, Palampur to evaluate the effect of drip irrigation levels applied at 40 and 80 per cent CPE and NPK fertigation levels on soil water retention, plant water, water use efficiency, productivity, nutrient uptake and nutrient use efficiency of capsicum under open and protected conditions and broccoli under open conditions. The treatments comprised of (a) Two drip irrigation levels viz., I0.4– Drip at 40 per cent Cumulative pan evaporation (CPE) and I0.8– Drip at 80 percent CPE (b) Four fertigation levels viz., F50 – 50 per cent recommended dose of fertilizer, F100– 100 per cent recommended dose of fertilizer, F150– 150 per cent recommended dose of fertilizer and F200– 200 per cent recommended dose of fertilizer (c) Farmer‟s practice - FYM @ 1 kg m-2 + 10 g m-2 IFFCO (basal) + 2 g L-1 of 19:19:19 at 15 days intervals and drip irrigation applied at the rate 2 L m-2 daily and (d) Recommended Practice (control) – 100 per cent NPK(by conventional method) + drip irrigation at 100 per cent CPE. Results indicated that the soil water content increased with increase in drip irrigation level from I0.4 to I0.8 with more profile water depletion in I0.4 as compared to I0.8 due to less quantity of water applied. Under fertigation treatments, the plant height and number of leaves, root length, volume and weight were significantly higher with F200 over other F100 and F50 under open as well as protected conditions leading to higher marketable yields, water use efficiency, NPK nutrient uptake, nutrient use efficiency and higher B.C ratio in capsicum as well as broccoli. The study concluded that drip irrigation at 0.4 CPE led to saving of water by 50 per cent over 0.8 CPE and increasing fertigation from 50 to 200 per cent RDF significantly increased the marketable yield, N, P & K uptake and Nutrient Use Efficiency in both the crops under open and protected conditionThesisItem Open Access EFFECT OF DRIP IRRIGATION ON SOIL-PLANT WATER DYNAMICS, NUTRIENT USE AND PRODUCTIVITY OF CAPSICUM AND BROCCOLI UNDER VARYING NPK FERTIGATION IN AN ACID ALFISOL(CSKHPKV, Palampur, 2016-04) Kapoor, RENU; Sandal, Sanjeev K.ABSTRACT In Hilly areas, the judicious use of the available water resources through drip irrigation under open and protected conditions becomes necessary to enhance the yield, nutrient and water use efficiency.

The soil of the experimental site was silty clay loam in texture; medium in organic carbon and low in available nitrogen and medium in available phosphorus and potassium. The experiment was conducted in split plot design with three replications. Forage species in sole stand as well as in the grass + legume mixture had taller plants, more number of shoots and better leaf stem ratio under different vegetative barriers. Setaria grass as vegetative barrier produced 87.69 and 88.49 per cent more green and dry fodder yields, respectively over no vegetative barrier. The respective increase by vegetative barrier of napier bajra hybrid was 76.60 and 81.55 per cent. Setaria grass + stylosanthes produced 25.42, 87.51 and 92.29 per cent more green fodder yield over setaria grass, stylosanthes and existing forage species, respectively, with respective increase of 11.75, 70.55 and 118.86 per cent in dry fodder yield. Higher net monetary returns of Rs. 23562 ha-1 and B: C ratio of 1.82 was obtained in vegetative barrier of setaria grass and followed by vegetative barrier of napier bajra hybrid. Setaria grass grown with stylosanthes resulted in significantly higher net returns of Rs. 28229 ha-1 and B: C ratio of 2.03. Better crude protein content, crude protein yield, calcium and magnesium contents and lower acid detergent fibre and neutral detergent fibre contents were observed in improved forage species. Setaria grass + stylosanthes also resulted in higher microbial biomass carbon content build up in the soil. Vegetative barriers as well as improved forage species helped to conserve the soil moisture content appreciably under degraded grassland conditionsThesisItem Open Access SOIL PLANT WATER DYNAMICS AND SOIL HEALTH AS AFFECTED BY NUTRIENT MANAGEMENT PRACTICES UNDER GRAM MAIZE CROPPING SEQUENCE(CSKHPKV, Palampur, 2016) DHIMAN, SHILVA; Dubey, Y.P.ABSTRACT An experiment was conducted at the farm of Department of Soil Science, CSKHPKV, Palampur during 2013-16 by taking gram-maize cropping sequence. There were three tillage treatments i.e. conservation tillage, conventional tillage and no tillage; and three nutrient management practices i.e. organic management, integrated management and RDF management (inorganic). Gram and maize was taken as main crops and wheat was grown with gram crop without any tillage practice i.e. integrated and RDF management. Aerobic and anaerobic composts were used in crop as soil application and for top dressing. The organic management with conventional tillage was found to be significantly superior with rest of the treatment combinations on yield attributes, symbiotic parameters and yield of gram in all the three years. The major constraints to grow gram at Palampur was the attack of root rot disease. The disease incidence was reduced through organic nutrient management with conventional tillage. The yield attributes and yield of maize was better in integrated management in first year and in organic management in second year. The conventional tillage in both the years registered significant impact on yield and yield attributes of maize. The yield and yield attributes was better in gram-maize cropping sequence than wheat-maize cropping sequence under integrated and RDF management. The protein and carbohydrate content of gram and maize in both seed and straw was found to be higher in organic management with conventional tillage. The nutrient content and uptake of nutrients was the highest in organic nutrient management with conventional tillage in all the crop growth stages in gram and at harvest whereas in maize it was the highest in integrated nutrient management with conventional tillage. The RLWC (Relative Leaf Water Content), LSC (Leaf Saturation Curve) and volumetric soil moisture content was recorded highest in organic management with conventional tillage in both gram and maize. All the physical properties except available water and SPR (Soil Penetration Resistance) were found to be higher in inorganic nutrient management with conventional tillage. The chemical properties i.e. pH, OC, total nitrogen and total phosphorus was found to be highest in organic nutrient management with conventional tillage whereas available N, P and K was found to be significantly higher in integrated nutrient management with conventional tillage in both surface and subsurface soil. The ammonical nitrogen in both surface and subsurface soil was found to be highest in inorganic nutrient management with conservation tillage whereas the nitrate nitrogen in both surface and subsurface soil was found to be higher in inorganic management with conventional tillage. The physical properties i.e. particle density, WHC (Water Holding Capacity), FC (Field Capacity), PWP (Permanent Wilting Point), AW (Available Water) and WSA (Water Stable Aggregates) were significantly and positively correlated with chemical and biological properties whereas SPR and ammonical nitrogen were negatively correlated. All the chemical properties were positively correlated with soil physical and biological properties except SPR and pore space. All the biological properties were positively and significantly correlated with physical and chemical properties except SPR, ammonical nitrogen and pore space. The physical, chemical and biological properties were generally positively correlated with each other except few parameters i.e. SPR, Ammonical nitrogen and pore space at both the depths.
