    Determination of nutrient requirement and contribution of nutrients from soil, FYM and fertilizers in turmeric in an acid Alfisol
    (Palampur, 2021-10-28) Prakriti; Dixit, S. P.
    The present study was carried out on turmeric var. Palam Pitamber during kharif 2021 at the experimental farm of Department of Soil Science, CSK HPKV Palampur, to determine the nutrients requirement, contribution of nutrients from the soil, FYM and fertilizers in turmeric in an acid Alfisol. The experiment was conducted on pre-established three fertility gradients which was divided into seventy two plots i.e. each gradient into twenty four plots. There were seventy two treatment combinations comprising of N, P, K and FYM. These treatments were formed by different combinations as per the standard procedure of soil test crop response correlation studies (STCR) and having four levels of N (0, 15, 30 and 45 kg N ha-1 ), P (0, 15, 30 and 45 kg P2O5 ha-1 ) and K (0, 30, 60 and 90 kg K2O ha-1 ) and three levels of FYM (0, 10 and 20 t ha-1 ). The soil was Typic Hapludalf, silty clay loam in texture, acidic in reaction (pH 5.47), medium in organic carbon (7.61 g kg-1 ), low in available nitrogen (256 kg ha-1 ), high in available phosphorus (31 kg ha-1 ) and medium in soil available potassium (190 kg ha-1 ). Soil samples (0-15 cm) collected before the sowing of turmeric crop were analyzed for pH, organic carbon and available N, P and K. The rhizome and haulm samples taken at harvest of turmeric were processed and analyzed to calculate nutrients uptake. The results revealed that the rhizome yield ranged from 94.21 to 224.0 q ha-1 , whereas the yield of haulm varied from 10.09 to 25.01 q ha-1 in different treatments. The total uptake of N, P and K ranged from 21.07 to 52.74, 5.84 to 14.45 and 25.70 to 66.94 kg ha-1 by turmeric, respectively. The amount of nutrients required to produce one quintal of rhizome was 0.25 kg nitrogen (N), 0.06 kg phosphorus (P) and 0.31 kg potassium (K). Per cent contribution of nitrogen (N), phosphorus (P) and potassium (K) from soil was 10.04, 27.26 and 15.57, fertilizer was 46.88, 16.33 and 53.14 and FYM was 3.23, 3.01 and 5.28, respectively. Fertilizer prescription equations were developed with the help of basic parameters viz. nutrient requirement, contribution of nutrients from soil, FYM and fertilizers. The ready reckoners were also generated at a different soil test values for different targets yield of the crop.

    Effect of management practices on productivity, quality of maize and soil properties in an acid hill soil
    (Palampur, 2021-10-07) THAKUR, CHANDAN; Sharma, Sanjay K
    Fertilizers play an important role in any crop production system but their imbalanced and sole application has been found to affect adversely the production potential, quality of produce as well as the soil health. The productivity of maize is quite low and there is ample scope to improve this by manipulating nutrient management systems in such a way that these are more eco-friendly, effective and largely acceptable. Natural farming system (NFS), involving no chemical fertilizers, very less amount of organic inputs prepared using the excreta from indigenous (‘Desi’) cows and other locally available inputs is being advocated for minimizing costs, maintaining the soil health and productivity as well as the quality of produce. Therefore, this investigation was carried out to study the effect of management practices on productivity and quality of maize grains and soil properties. The experiment comprised of eleven treatments involving recommended NPK levels, and their integration with FYM and lime, organic farming package, three natural farming system practices involving formulations based on excreta of indigenous and crossbred cows and buffalo, and their supplementation with 25 per cent of recommended NPK. The NFS formulations (beejamrit, jeevamrit and ghan-jeevamrit) differed markedly with respect to NPK contents, pH, microbial counts and total dissolved solids. Application of 100 per cent NPK + FYM resulted in better growth and recorded the highest maize grain (42.25 q ha1 ) and stover yield (71.82 q ha-1 ) but was statistically at par with 100 per cent NPK + lime. Among organic/NFS treatments, sole organic farming treatment recorded significantly higher maize grain equivalent yield (29.13 q ha-1 ) in comparison to NFS based on crossbred cow (24.15 q ha-1 ) and NFS based on buffalo (23.07 q ha-1 ) but was at par with NFS based on indigenous cow (26.54 q ha-1 ). Supplementation with 25 per cent NPK in these treatments significantly enhanced the yield over pure organic/natural farming system treatments. Similar trend was also observed for NPK uptake by maize. Reducing sugars, non-reducing sugars, ash and crude protein as well as available NPK contents were also higher under 100 per cent NPK + FYM, closely followed by 100 per cent NPK + lime treatment. However, carbohydrates, starch, phosphorus, magnesium, zinc and iron contents were higher under pure organic farming and natural farming system treatments in comparison to treatments involving use of chemical fertilizers. Organic carbon, bulk density, water holding capacity, mean weight diameter, and Mg in soils along with the microbiological characteristics were recorded higher in organic farming + 25 per cent NPK treatment but Ca was recorded highest in 100 per cent NPK + lime treatment. A significant and positive correlation was found for maize grain equivalent yield and nutrients uptake with soil properties for organic and natural farming system treatments. Hence, there was a notable effect of management practices on productivity, quality of maize and soil properties in an acid hill soil, with conventional integrated nutrient management system giving the better results for most of the parameters under study

    Effect of subsurface drip irrigation and drip line layering on soil water dynamics and productivity of tomato under protected environment
    (Palampur, 2021-09-22) Sharma, Ankita; Sandal, Sanjeev K.
    The present study was conducted at experimental farm of CSKHPKV, Palampur during the year 2020 with the objectives to evaluate the effect of subsurface drip irrigation and drip line layering on soil water dynamics, plant water content & water productivity, and to evaluate the effect of subsurface drip irrigation and drip line layering on nutrient uptake and crop productivity. The treatments comprised of two drip irrigation levels 0.4 PE (40 per cent of pan evaporation) and 0.8 PE (80 per cent of pan evaporation) with five subsurface layering viz., no layering, farm yard manure @ 10 t/ha, rice straw @ 10 t/ha, saw dust @ 10 t/ha, chopped weed biomass @ 10 t/ha. The tomato (Lycopersicum esculentum) crop was transplanted on May 4, 2020. The experimental results indicated that the soil water content and soil water stock was higher under 0.8 PE treatments which led to significantly higher plant height, relative leaf water content, marketable and straw yield as compared to 0.4 PE treatments. Among subsurface layering, plant height, marketable and straw yield, total NPK uptake were significantly higher under farm yard manure and lower under no layering. However, the root growth parameter was significantly higher under rice straw and lower under no layering. The gross return and B:C ratio were the highest under 0.8 PE + Farm yard manure and lowest under 0.4 PE + No layering treatment combination. The study concluded that the sub surface drip irrigation level of 0.8 PE and subsurface layering with Farm yard manure were the optimum treatment combination for obtaining maximum crop and water productivity
