    EFFECT OF DIFFERENT SOURCES OF SULPHUR ON YIELD, QUALITY OF CAULIFLOWER AND SULPHUR FRACTIONS IN AN ACID ALFISOL
    (CSKHPKV Palampur, 2016-07) NEHA; Sharma, Sanjay K
    A field experiment was conducted during rabi 2014-15 on cauliflower (Brassica oleracea L. var. Palam Uphar) at the experimental farm of Department of Soil Science, College of Agriculture, CSK Himachal Pradesh Krishi Vishvavidyalaya, Palampur. The experiment consisted of three levels (12.5, 25, 37.5 kg S ha-1) and four sources (Sartaj natural gypsum, locally available gypsum, elemental sulphur and single super phosphate) of sulphur along with one control in a randomized block design. The application of sulphur @ 37.5 kg S ha-1 influenced growth parameters, yield attributes, quality, harvest index and per cent marketable curds significantly over 12.5 kg S ha-1. Likewise, highest net curd yield (113 q ha-1) was recorded with the application of 37.5 kg S ha-1, which was however, statistically at par with that obtained with the application of 25 kg S ha-1 (105.2 q ha-1) but significantly superior to that obtained with the application of 12.5 kg S ha-1 (89.5 q ha-1). Control recorded the lowest net curd yield (77.8 q ha-1). Among sources, Sartaj gypsum recorded maximum value of all these parameters followed by single super phosphate, locally available gypsum and elemental sulphur. Likewise, Sartaj gypsum recorded highest net curd yield (114.2 q ha-1) which was however, statistically at par with single super phosphate (102.9 q ha-1). The uptake of N, P, K, S, Fe, Mn, Cu and Zn by cauliflower increased with increased level of sulphur and followed the yield trend. Among sources, Sartaj gypsum recorded maximum nutrient uptake by cauliflower followed by single super phosphate. The different levels and sources of sulphur did not show any significant effect on soil pH, organic carbon, available K, Fe, Mn, Cu and Zn but had a significant effect on soil available N and P content. In case of fractions, available, water soluble, organic and total sulphur increased significantly with increased levels of sulphur. Sartaj gypsum recorded maximum value of available sulphur (12.4) and water soluble (9.8) followed by single super phosphate, locally available gypsum and elemental sulphur. Different sources of sulphur did not show any significant effect on heat soluble sulphur, organic sulphur and total sulphur. All sulphur fractions were significantly and positively correlated with yield, quality of cauliflower and sulphur fractions. However, higher correlation values were observed with water soluble and available sulphur and least with heat soluble sulphur. Maximum gross returns, net returns per hectare and gross returns per rupee invested were found when sulphur was applied @ 37.5 kg S ha-1 (Rs. 113083, 62286, 2.23, respectively) which was significantly superior to 12.5 kg S ha-1 (Rs. 89417, 40921, 1.84, respectively) but at par with 25 kg S ha-1(Rs. 105333, 55688, 2.13, respectively).

    EVALUATION OF PRESCRIPTION BASED FERTILIZER RECOMMENDATIONS IN SYSTEM OF RICE INTENSIFICATION (SRI) IN WET TEMPERATE ZONE OF HIMACHAL PRADESH
    (CSHHPKV Palampur, 2016-07-05) MITTAL, SHREYANSH; Sharma, Sanjay K.
    A field experiment was conducted during kharif 2015 at the Experimental Farm of Department of Soil Science, CSK HPKV, Palampur to study the effect of different approaches of fertilizer application on growth parameters and productivity; soil physico-chemical properties; nutrients uptake and economics of rice under SRI. There were eight treatments (control, farmers‟ practice, general recommended dose, soil test based, yield targets 3.5, 4.0, 4.5 and 5.0 t ha-1 replicated thrice in a randomized block design (RBD). The soil of experimental field was silty clay loam in texture, acidic in reaction ( pH 5.5), high in organic carbon (11.2 g kg-1 ), medium in available N (320 kg ha-1 ), high in available P (30 kg ha-1 ), low in available K (112 kg ha-1 ) and sufficient in micronutrients. Soil samples (0-0.15 m) were collected before sowing, at 50% flowering and at harvest for chemical analysis. Plant samples were collected at 50% flowering and harvest and analyzed for N, P, K contents whereas, micronutrients (Fe, Mn, Zn and Cu) concentration in grain and straw at harvest was also determined after harvest of crop. Growth parameters and yield attributes were also recorded at specified intervals. All the levels for prescription based fertilizer application gave significantly higher grain and straw yield as compared to other approaches of fertilizer application barring few exceptions. Further, treatment for yield target of 5.0 t ha-1 resulted in maximum growth (plant height, total number of effective tillers, panicle length, 1000 grain weight, spikelet fertility percentage, number of grains per panicle), grain (4.46 t ha-1 ) and straw (10.03 t ha-1 ) yield. Targeted yield treatments significantly increased the nutrients uptake over other approaches of fertilizer application. The status of N, P and K was higher in STCR based fertilizer treatments at 50% flowering as well as at harvest of the crop. The STCR based fertilizer application treatments excelled all other approaches of fertilizer application in terms of net returns and benefit cost ratio. However, STCR approach for transplanted rice worked satisfactorily up to yield target of 4.0 t ha-1 beyond which deviation in yield from targeted yield was more than 10 per cent. Soil test based and general recommended dose of fertilizers recorded better plant growth and yield, and increased the nutrients uptake and N, P and K status in soil as compared to the farmers‟ practice and control.

    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.

    EFFECT OF DRIP IRRIGATION AND FERTIGATION ON YIELD AND QUALITY OF STRAWBERRY UNDER PROTECTED CULTIVATION
    (CSHHPKV Palampur, 2017-06) JASWAL, RICHA; Sandal, Sanjeev K.
    The present study was conducted at experimental farm of CSK HPKV, Palampur, during the year 2015-16 with the objectives of evaluating the effects of drip irrigation and NK fertigation levels on soil water retention and transmission, plant water, water use efficiency, growth, productivity, quality and nutrient uptake of strawberry under protected condition. The treatments comprised of, (a) Three drip irrigation levels, DI0.6 (Daily drip irrigation at 60 per cent of open pan evaporation), DI0.8 (Daily drip irrigation at 80 per cent of open pan evaporation) and DI1.0 (Daily drip irrigation at 100 per cent of open pan evaporation), (b) Three NK fertigation levels viz., NK50 (50 per cent of RDF of which 25 per cent applied as basal and rest 75 per cent through fertigation at weekly interval), NK75 (75 per cent of RDF of which 25 per cent applied as basal and rest 75 per cent through fertigation at weekly interval) and NK100 (100 per cent of RDF of which 25 per cent applied as basal and rest 75 per cent through fertigation at weekly interval) and (c) Control (C)- 100 per cent RDF applied through conventional method (1/2 N and full PK as basal and remaining 1/2 N in equal split at monthly intervals) with drip irrigation at 1.0 PE. The strawberry cv. Chandler was transplanted on October 03, 2015. The results indicated that DI1.0 and DI0.8 treatment had higher soil water content, soil water stock, profile water recharge in comparison to DI0.6. The DI1.0 treatment due to favorable soil moisture regimes led to higher relative leaf water content and TSS content and NPK uptake while WUE and vitamin C were higher in DI0.6. In case of different NK fertigation treatment, NK100 and NK75 had higher root growth, leaf area index, WUE, FEE, fruit length, breadth and weight, TSS content and higher marketable yield as compared to NK50 treatment. The study concluded that fertigation application of 100 per cent RDF at 0.6 PE level resulted in higher water use efficiency and saving irrigation water. However, the maximum marketable yield, gross and net returns and highest B:C ratio was obtained with DI0.8 NK100.
