    Genetic variability and interrelationship among horticultural traits in faba bean (Vicia faba L.)
    (palampur, 2017-06-30) Sharma, Simran; Singh, Yudhvir
    The present investigation entitled, “Genetic variability and interrelationship among horticultural traits in faba bean (Vicia faba L.)” was undertaken at the Research Farm of the „Department of Vegetable Science and Floriculture‟, College of Agriculture, CSK HPKV, Palampur during winter season 2015-16. The experimental material comprising of thirty five genotypes of faba bean including one check namely, „Vikrant-B‟ were evaluated in randomized block design over three replications to assess the nature of genetic variability, association among various traits, and their direct and indirect effects on pod yield per plant for effective selection. Data were recorded on nineteen characters viz., days to 50 per cent flowering, node at which first flower appears, branches per plant, pods per node, nodes per plant, plant height (cm), days to maturity, pod length (cm), pods per plant, pod yield per plant (g), seeds per pod, seed yield per plant (g), seed size (cm), 100-seed weight (g), harvest index ( per cent), total soluble solids (oBrix), dry matter ( per cent), ascorbic acid (mg/100g) and protein content ( per cent). In addition, morphological characterization for seed colour was also recorded visually. The observations were recorded on ten competitive plants which were randomly selected in each entry over the replications. On the basis of mean performance, „Local-1-C‟ was the top ranking genotype for pod yield per plant which significantly outperformed all the genotypes with an increase in yield of 44.58 per cent over check „Vikrant-B‟. In addition, fifteen genotypes produced pod yield similar to that of „Vikrant-B‟. HB-123-B (54.00g), HB-123-C (51.00g), HB-511-C (48.00g), PRT-7-B (46.87g), HB-40-A (46.67g) and HB-193-A (45.33g) were the top performing genotypes among them. The superior performance of these genotypes for fresh pod yield per plant was mainly attributed to their superior/comparable performance for pods per node, nodes per plant, pod length, pods per plant, branches per plant, seed yield per plant, 100-seed weight to that of best performing check „Vikrant-B‟. High heritability along with high genetic advance was observed for node at which first flower appears, pods per plant, harvest index, protein content and pod yield per plant indicating the inheritance of these characters under the control of additive gene action and selection would be more effective for their improvement. Based on correlation and path coefficient analysis, nodes per plant, pods per plant, branches per plant, seed yield per plant, seed size, 100-seed weight, harvest index and protein content could be considered as the best selection parameters for evolving high yielding genotypes.

    Economic analysis of tomato under protected and open environment in Kangra District, H.P.
    (palampur, 2017-07-15) Mehta, Kanika; Guleria, J.S.
    The present study pertained to economic analysis of tomato under protected and open environment in Kangra District, H.P. This study is based upon the data collected for the Agricultural Year 2015-16 from 60 tomato (30 open-field and 30 polyhouse) growers, selected through proportional allocation method from Baijnath and Bhedu Mahadev blocks of Kangra District, Himachal Pradesh. The study reveals that under open-field/ natural conditions, among vegetables, the average yield of tomato crop was found to be the highest in the study area. Under protected conditions, the maximum cropped area was found to be under tomato (52.59%) followed by capsicum (21.04%) and cucumber (14.83%). Human labour was found to be the most important component of tomato cultivation under both open-field and protected conditions, accounting for 73.43 per cent and 82.68 per cent of the total variable cost, respectively. Under open-field conditions, the net returns over variable cost was Rs. 2,32,282/ha and output-input ratio stood at 1.50:1. Under protected conditions, it was found that all types of costs viz. variable, fixed and total costs declined with the size of the holding, mainly due to economies of scale. Further, it was found that the returns over total cost and variable cost were higher on small farms in comparison to large farms. The output-input ratio stood at 1.15:1, on overall basis. Protected cultivation contributed 10.68 per cent in the total annual gross household income of the polyhouse growers, at overall level. Large polyhouse category earned higher proportion (14.52%) as compared to small category (7.02%). The income variability of polyhouse growers was found to be less in comparison to the open-field growers. Unavailability of improved varieties at the time of sowing, the high cost of improved varieties, lack of awareness regarding the high yielding and resistant varieties, lack of storage facilities, etc. were the major problems faced by open-field growers in the study area. In case of polyhouse growers, the lack of knowledge about site, orientation, material etc., non-serious approach of construction companies, problem of repairs/spare parts, lack of technical knowhow and training, inadequate extension and advisory services, etc. were the major problems. The study has suggested that efforts are required for creating cold storage facilities to increase the shelf life of tomato. Aside from prolonging the shelf life of the crop, product diversification through processing may enhance the income of tomato growers in the study area. There is a dire need to bring polyhouses under insurance cover to make the scheme more sustainable in future.

    (palampur, 2017-07-17) Rana, Jyotika; Negi, SC
    The field experiment was conducted to study the effect of integrated nutrient supply system in rice-wheat cropping system during 2016-17 at Badhiarkhar Research Farm of Department of Agronomy, Forages and Grassland Management, CSKHPKV, Palampur. The treatments comprising of T1 - Control (No fertilizer, no manure), T2 - 50% NPK to both rice and wheat, T3 - 50% NPK to rice and 100% NPK to wheat, T4 - 75% NPK to both rice and wheat, T5 - 100% NPK to both rice and wheat, T6 - 50% NPK + 50% N (FYM) to rice and 100% NPK to wheat, T7 - 75% NPK + 25% N (FYM) to rice and 75% NPK to wheat, T8 - 50% NPK + 50% N (wheat cut straw) to rice and 100% NPK to wheat, T9 - 75% NPK + 25% N (wheat cut straw) to rice and 75% NPK to wheat, T10 - 50% NPK + 50% N (green manure) to rice and 100% NPK to wheat, T11 - 75% NPK + 25% N (green manure) to rice and 75% NPK to wheat and T12 -Farmers‟ Practice (40% NPK and FYM 5 t/ha to both the crops) were evaluated in a randomized block design with four replications. Soil of the experimental site was silty clay loam in texture, acidic in reaction, high in available nitrogen, and medium in available phosphorus and potassium. Significantly higher absolute growth rate and plant height, higher dry matter accumulation, number of shoots, CGR & RGR were recorded in T6 incase of rice. In case of wheat, initial plant stand at complete emergence, plant height, number of shoots and dry matter accumulation at different stages were also maximum in T6. The days taken to 50% flowering/earing as well as maturity were minimum in the treatment comprising of 50% NPK along with FYM in rice (T6).The study revealed that T6 resulted in higher tillers, panicles, grains per panicle, 1000 grain weight, seed, straw & biological yield of rice. In case of wheat, higher number of spikes, number of grains per spike, length of spike, grain weight per spike, 1000 grain weight, seed, straw and biological yield were found in T6. Pooled data of 22 years from 1994-95 to 2016-17 showed that the maximum yield was recorded in T6. The net returns of the system was maximum in treatment T6 while the benefit cost ratio was maximum in treatment T5. The treatment comprising of 50% NPK + 50% N (FYM) to rice and 100% NPK to wheat (T6)was found to be the best treatment for getting higher productivity and profitability followed by T10 and T5.

    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.

    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.

    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.
