    NITROGEN DYNAMICS AS INFLUENCED BY LONGTERM EFFECT OF PRESCRIPTION BASED FERTILIZER APPLICATION IN AN ACID ALFISOL
    (CSHHPKV Palampur, 2014-07-07) SHABNAM; Sharma, Sanjay K.
    The present investigation was carried out in the ongoing long-term experiment on soil test crop response correlation studies (STCR) initiated during kharif, 2007 at the experimental farm of Department of Soil Science, College of Agriculture, CSK HPKV, Palampur in randomized block design with eight treatments comprising control, farmers’ practice, general fertilizer dose, conventional soil test based fertilizer application and fertilizer application based on STCR approach with and without FYM for yield targets of 30 and 40 q ha-1 . The soil of the experimental site was Typic Hapludalf, silty clay loam in texture, acidic in reaction, medium in organic carbon, low in available N, high in P and medium in K at the initiation of the experiment. Soil samples (0-0.15m) taken after the harvest of maize (kharif, 2013) were analyzed for different forms of nitrogen and pH, OC, CEC, microbial biomass carbon and available N, P and K. Grain and stover yields of maize were recorded and uptake of various nutrients by maize was also worked out after the plant analysis. Continuous application of chemical fertilizers either alone or in combination with FYM enhanced the contents of different organic and inorganic nitrogen fractions. However, prescription based fertilizer application involving conjunctive use of fertilizers and FYM for yield targets of 30 and 40 q ha-1 proved superior to general fertilizer recommendation as well as conventional soil test based fertilizer application in influencing various forms of nitrogen. Likewise, highest contents of OC (8.3 g kg-1 ), CEC (13.4 c mol (p+ ) kg-1 ), microbial biomass carbon (119.5 mg kg-1 ), available N (282 kg ha-1 ), P (61 kg ha-1 ) and K (279 kg ha-1 ) were found under STCR (IPNS) based treatment for target yield of 40 q ha-1 which ultimately, resulted in the highest productivity of maize (37.6 q ha-1 ). In general, the contribution of different organic as well as inorganic forms of nitrogen viz., hydrolysable ammonical-N, amino acid-N, serine+threonine-N, hexosamine-N, unidentified-N, non hydrolysable-N, ammonical-N and nitrate-N, towards the total-N was 24.3, 24.4, 5.4, 7, 23, 6.4, 5.5 and 3.6 percent, respectively. Continuous cropping without fertilization resulted in depletion in hydrolysable ammonical-N, amino acid-N, serine+threonine-N, hexoseamine-N, unidentified-N and non-hydrolysable-N to the extent of 24, 17, 23, 3.6, 12 and 8 per cent, respectively. Hydrolysable ammonical-N exhibited highest correlation with available N (r=0.882) and accounted for 78 percent variation in available N. Hydrolysable ammonical-N recorded highest correlation with grain yield (r=0.898) and accounted for about 88 per cent of the variation, whereas, amino acid-N showed the highest correlation with stover yield (r=0.902) and accounted for about 81 per cent of the variation. Different fractions of nitrogen were found to be positively and significantly correlated with one another except non hydrolysable-N.

    INFLUENCE OF ZINC AND BORON ON WHEAT PRODUCTIVITY AND POTASSIUM USE EFFICIENCY IN AN ACID ALFISOL
    (CSHHPKV Palampur, 2012-12-01) NEHA; Sharma, R.P.
    The present investigation was carried out at experimental farm of Department of Soil Science, College of Agriculture, CSK HPKV, Palampur with sixteen treatments consisting of four levels of K (0, 50,100 and150% of recommended dose), two levels of Zn (0 and 10 kg ha-1 ) and two levels of B (0 and 1 kg ha-1 ) in factorial randomized block design. Application of K @ 50, 100 and 150 per cent of recommended dose increased plant height, dry matter accumulation, total and effective tillers per metre row length, grains per ear and test weight significantly. Similarly, application of Zn (10 kg ha-1 ) and B(1 kg ha-1 ) influenced these growth and yield attributes of wheat significantly. Highest grain (42.52q ha-1 ) and straw (66.80q ha-1 ) yield of wheat was recorded under 150 per cent of recommended dose of K. Application of 150 percent of recommended dose of K increased grain and straw yield by 43.7 and 46.9 per cent over no K, respectively. Application of Zn (10 kg ha-1 ) increased grain and straw yield by 10.9 and 9.8 per cent over no Zn, respectively. The increase in grain and straw yield with the application of B (1 kg ha-1 ) was 5.6 and 6.3 per cent, respectively. Application of K increased N, P, K, Mn, Fe, Cu and B contents significantly at maximum tillering and harvesting. Application of Zn increased Zn and B contents significantly at both the stages but the contents of Fe, Mn and Cu decreased. However, B increased the contents of Zn and B only at maximum tillering stage and Zn, Mn and B at harvesting (grain and straw). Almost similar effects of K, Zn and B application on total nutrient uptake were observed. Application of Zn increased partial factor productivity, physiological efficiency, agronomic efficiency and apparent recovery. B application increased partial factor productivity and apparent recovery only. Application of K, Zn and B increased available K, DTPA extractable Zn and available B content significantly, respectively.

    Evaluation of multi-nutrient extractants for determination of available P, K and micronutrient cations for soil analysis in Himachal Pradesh
    (CSHHPKV Palampur, 2015-08-14) SHARMA, ANKITA; Sharma, Sanjay K
    Multi-nutrient extractants offer alternative for conventional methods as more nutrients can be extracted in one go. However, the suitability and accuracy of such extractants for the determination of available nutrients must be verified. Therefore, sixty soil samples (0-0.15 m depth) collected randomly from different districts of Himachal Pradesh were used to evaluate the efficiency of AB-DTPA and AAAc-EDTA in comparison to their standard methods for P, K and micronutrient cations. Soil pH (1:2.5), EC (µS cm-1 ), OC (g kg-1 ), textural class, and CEC (cmol (p+ ) kg-1 ) soil under study ranged from 5.67-7.56, 61-695, 2.8-27.7, sandy loam to clay loam and 4.1- 15.0, respectively. Available P (kg ha-1 ) extracted by four methods viz., Olsen P, Bray P1, AB-DTPA P and AAAc-EDTA P varied from 7.8-44.3, 9.5-61.1, 6.5-38.8, 10.5- 52.1; available K (kg ha-1 ) extracted by three methods viz., NH4OAc, AB-DTPA and AAAc-EDTA ranged from 103.6-372.3, 86.6-364.9 and 74.6-362.5. Likewise, DTPA, AB-DTPA and AAAc-EDTA extractable contents of Cu, Fe, Zn and Mn ranged from 0.3-5.8, 1.0-6.3 and 1.2-5.0; 3.9-42.2, 8.1-58.8 and 7.3-32.7; 0.2-6.6, 0.3-6.7 and 3.3- 26.2, 5.1-27.2 and 7.7-38.3, respectively. Bray P1 method of phosphorus determination extracted more amount of available P followed by AAAc-EDTA, Olsen and AB-DTPA methods. Likewise NH4OAc extracted more K followed by AB-DTPA and AAAc-EDTA. In case of micronutrients cations, AB-DTPA in general, extracted more amounts as compared to DTPA alone. Overall, phosphorus showed highly significant correlations with physico-chemical properties. Among methods of extraction for P, AAAc-EDTA showed higher correlation with the standard method (Olsen P) of determination. Available K contents determined by AB-DTPA and AAAc-EDTA were well correlated with standard method (NH4OAc) however; AAAc-EDTA had higher correlation with AB-DTPA method for K extractability. In case of micronutrients, all the methods correlated positively and significantly with each other Highest significant correlations were observed between AB-DTPA and DTPA for Cu, Fe and Zn. However, in case of Mn, the highest correlation was observed between AB-DTPA and AAAc-EDTA. Both, AB-DTPA and AAAc-EDTA methods were more economical compared to the conventional methods.
