    EFFECT OF FEEDING SEABUCKTHORN CAKE (HIPPOPHAE L.) ON EGG PRODUCTION IN POULTRY AND GROWTH IN CALVES
    (CSKHPKV, Palampur, 2011-11-16) MD., HASANUZZAMAN; Sharma, V.K.
    ABSTRACT Balanced and effective feeding are the most important prerequisites for economic production of livestock and poultry. So, minimization of feed cost would be a great achievement for livestock and poultry farmers if the unconventional but potential ingredient like Seabuckthorn (SBT) cake would be introduced as the replacer of major protein sources, as nutritionally, SBT cake is very rich in proteins, fat, amino acids, vitamins and minerals. Very little systematic and scientific work has been conducted to study the effects of feeding SBT cake to the livestock and poultry. Hence, the present study was envisaged to see the effect of replacement of CP of conventional feed of layers and calves, with that of SBT cake to evaluate biological performances, nutrient utilization, rumen metabolites and cost benefit ratio by feeding SBT cake. Three experiments were conducted to study the effect of SBT cake on layers and calves production. First trial was conducted in 360 BV-300 layer chicks which were offered conventional rations in control (S0) group and replacing 10, 20, 30, 40 and 50 per cent CP by SBT cake CP. The second experiment was aimed to study the effect of SBT cake on growth of calves where 18 calves of 4-5 months age were divided in 3 treatment groups having 6 animals in each group. The conventional CGR was offered in control group (SBT0) and replacing 50 per cent and 75 per cent CP of the control group with the CP of SBT cake in SBT50 and SBT75 groups respectively. One more trial was conducted as a third experiment, aimed to observe the effect of SBT cake on rumen metabolites and rumen microbial population in adult cattle. Three adult cattle (fistulated) were maintained on three rations with a switch over design. The crude protein contents of the basal ration (T1) were replaced with SBT cake CP at 50 (T2) and 75 (T3) per cent CP in the adult cattle ration. The egg production, egg mass and body weight gain of layers were higher in S20 group where 20 per cent CP of conventional concentrate was replaced with the CP of the SBT cake. FCR in respect of egg mass as well as biological performance of the layer was found better in S20 treatment group. It was noticed that, as the level of SBT cake increased beyond 20 per cent, the biological performance of the layers declined though the quality traits of eggs were not affected by replacement of SBT cake at any level. It was revealed that replacement of CP of conventional layer feed with SBT cake CP up-to 20 per cent level was economic for layer production. Higher body weight gain and better balance of nutrient in calves was observed in SBT50 group where 50 per cent CP of the traditional CGR was replaced with the SBT cake CP. Better FCR of calves was found in SBT50 group, hence, can be considered as the highest dose of replacement with SBT cake CP in CGR. Higher microbial population in older calves was found in T2 group, where 50 per cent CP of the traditional adult calves ration was replaced with the CP of SBT cake. Better rumen metabolites were also found in the T2 group. Looking at the results of present investigations, it could be concluded that 20 per cent CP of the traditional concentrate ration could be replaced with the CP of SBT cake in layer birds for a viable and cost effective egg production, whereas, 50 per cent CP of the traditional calves ration could be replaced with the CP of SBT cake in young as well as older calves to improve the nutrient utilization efficiency for sustainable livestock production.

    LINE X TESTER ANALYSIS FOR HYBRID PERFORMANCE, HETEROSIS AND COMBINING ABILITY IN TOMATO (Solanum lycopersicum L.)
    (CSK Himachal Pradesh Krishi Vishavavidyalaya, Palampur, 2011) KAPUR, POOJA; Vidyasagar
    Bacterial wilt resistant determinate lines (7) and indeterminate testers (4) alongwith 28 hybrids developed as per line x tester mating design were evaluated alongwith standard check Avtar (7711) in Randomized Block Design with three replications at the Experimental Farm of Department of Vegetable Science and Floriculture, CSK HPKV, Palampur during summer-rainy season of 2009 and 2010. Observations were recorded on incidence of bacterial wilt disease, fruit yield and component traits. The analysis of variance indicated significant differences among treatments for marketable yield and other component traits in all the environments. The hybrid L4 x T3 (BWR-5 x 16-B) surpassed all the hybrids and the standard check in all the environments and recorded 2.21 kg marketable fruit yield per plant in comparison to 1.04 kg per plant in the standard check Avtar (7711). Line x tester analysis revealed significant differences due to lines, testers, line x tester interactions. Interactions of lines, testers and line x tester with environment exhibited significant differences for most of the traits indicating the importance of testing parents as well as hybrids across environments. Non-additive gene action was higher for the traits days to 50 per cent flowering, marketable yield per plant, pericarp thickness, plant height and harvest duration which reaffirm the importance of hybrids in tomato. Additive gene action was higher for the traits days to first harvest, gross yield per plant, fruit weight, fruit shape index, locules per fruit and TSS, which could be exploited by developing superior pure lines/inbreds through hybridization and biparental matings. The lines 7-2 (L7) and BWR-5 (L4) and the testers 16-B (T3) and CLN 1314G (T4) proved to be the most potential parents whereas L4 x T3 (BWR-5 x 16-B) as the most promising hybrid combination.

    (CSK Himachal Pradesh Krishi Vishavavidyalaya, Palampur, 2010) KUMARI, NISHA; Pathania, N.K.
    The studies entitled “Integrated management of nitrogen and phosphorous through bio-inoculants and organic manures in sprouting broccoli – brinjal cropping sequence under mid - hill conditions of Himachal Pradesh” were conducted at the experimental farm of Department of Vegetable Science and Floriculture, College of Agriculture, CSKHPKV, Palampur (HP) with the objectives to study the effect of organic manures, bio-inoculants and chemical fertilizers on yield and quality parameters, to study the response of various sources of organic and inorganic fertilizers on uptake of nutrients and to work out economics of different treatments. The fifteen treatments comprising of three levels of each nitrogen and phosphorous (50%, 75% and 100%),three bio-inoculants (Azotobacter, Azospirillum and Phosphorous Solubilizing Bacteria) and two organic manures (farmyard manure and vermicompost) were laid out in RBD with three replications during Sep,06 to Sep,2008. The response of different integrated nutrient management treatments in sprouting broccoli variety Palam Samridhi revealed significant variation with respect to various parameters studied. Maximum values for days to first harvest (94.5), plant height (49.6cm), plant spread (2809.1cm2), number of leaves per plant (17.2), terminal head weight (175.5g), number of spears per plant (8.6), spear yield per plant (108.1g), harvest index (27.5%), marketable yield per plant (287.5g), marketable yield per hectare (106.4q), vitamin C (98.6 mg/100g), dry matter (13.9%), gross returns (Rs 1,59,600/ha), net returns (Rs 1,00,507/ha) and benefit cost ratio (2.70) were recorded in treatment T14 (100% NPK + FYM + Azospirillum) followed by treatment T13 (100% NPK + FYM + Azotobacter). The maximum uptake of nitrogen (134.0 kg/ha), phosphorous (24.81 kg/ha) and potassium (124.95 kg/ha) were observed in treatment T14 (100% NPK + FYM + Azospirillum), T15 (100% NPK + FYM+ PSB) and T13 (100% NPK + FYM + Azotobacter), respectively. The response of different integrated nutrient management treatments in brinjal variety Arka Keshav also revealed significant variation for the various traits except days to first picking. The minimum days to 50% flowering (53.1) and maximum values for number of branches per plant (8.5), plant height (87.7cm), fruit length (22.4cm), fruit girth (9.6cm), total number of fruits per plant (27.2), average fruit weight (38.1g), number of marketable fruits per plant (15.5), marketable yield per plant (440.6g), marketable yield per hectare (163.2q), vitamin C (17.9mg/100g), dry matter(8.5%), gross returns (Rs 1,30,560/ha), net returns (Rs 69,620/ha) and benefit cost ratio (2.14) were obtained in treatment T14 (100% NPK + FYM + Azospirillum) followed by treatment T13 (100% NPK + FYM + Azotobacter) . Total uptake of nitrogen (85.34kg/ha) and potassium (80.96 kg/ha) was the highest in T14 (100% NPK +FYM + Azospirillum) whereas, treatment T15 (100% NPK + FYM + PSB) recorded highest total phosphorus uptake (22.43kg/ha).The highest values with respect to N, P and K over the pooled years were 323.2 (T13), 21.0 (T15) and 249.0 kg/ha (T13), respectively, which resulted in build up of 31.3 kg/ha N, 7.05kg/ha P and 28.0kg/ha K over the initial status of the soil. The studies revealed that 100% NPK (125:75:50 in sprouting broccoli and 100:50:50kg/ha in brinjal) + farmyard manure (20t/ha) + Azospirillum (seedling dip) were found best for obtaining higher values w.r.t. growth, yield, quality parameters, nutrient uptake and available nutrients (NPK kg/ha) in sprouting broccoli and brinjal. This treatment resulted in higher yield of 16.3 and 7.2 per cent and benefit cost ratio of 2.70 and 2.14 over recommended practice in sprouting broccoli and brinjal, respectively. The application of 100%NPK (125:75:50 in sprouting broccoli and 100:50:50kg/ha in brinjal)+farmyard (20t/ha) manure+ Azotobacter (seedling dip) was observed next best treatment. Based on two years studies, it can be concluded that application of 125:75:50kg NPK/ha+20 tonnes farmyard manure+Azospirillum (seedling dip) in sprouting broccoli and 100:50:50kg NPK/ha+20 tonnes farmyard manure + Azospirillum (seedling dip) in brinjal resulted in highest yield, better quality produce, highest net returns as well as benefit cost ratio in mid-hill conditions of Himachal Pradesh. _____________

    HETEROSIS AND COMBINING ABILITY STUDIES FOR YIELD AND HORTICULTURAL TRAITS IN BELL PEPPER (Capsicum annuum L. var. grossum Sendt.) UNDER PROTECTED ENVIRONMENT
    (CSK Himachal Pradesh Krishi Vishavavidyalaya, Palampur, 2011) DEVI, MAYANGLAMBAM BILASHINI; Pathania, N.K.
    The present investigation entiled “Heterosis and combining ability studies for yield and horticultural traits in bell pepper (Capsicum annuum L. var. grossum Sendt.) under protected environment” was carried out in 25×10 m modified naturally ventilated polyhouse during summerautumn, 2012 and 2013 in Randomized Block Design having three replications to ascertain the quantum of genetic variability available in the bell pepper genotypes, gather information regarding the type of gene action and identify potential parental lines and cross combinations for protected environment on the basis of combining ability and magnitude of heterosis for different traits, viz., days to 50 per cent flowering, days to first harvest, number of marketable fruits per plant, pericarp thickness (mm), lobes per fruit, fruit length (cm), fruit width (cm), average fruit weight (g), marketable fruit yield per plant (kg), plant height (cm), harvest duration (days), ascorbic acid content (mg/100g) and capsaicin content (%). High estimates of PCV and GCV were observed for number of marketable fruits per plant, marketable fruit yield per plant, ascorbic acid content and capsaicin content indicating the presence of substantial variability for the traits and thereby ensuring ample scope for improvement of these traits through phenotypic selection. The high estimates of heritability coupled with high estimates of genetic advance (as per cent of mean) were observed for marketable fruit yield per plant, number of marketable fruits per plant and ascorbic acid content, which indicated the importance of additive gene action for the inheritance of these traits. On the basis of hybrid vigour, the cross combinations viz., Kashmir Sel-1 (L2) × Solan Bharpur (T1), ARCH-19 (L1) × Solan Bharpur (T1) and UHFSP(Y)-11 (L11) × Yolo Wonder (T3) were observed to be potential crosses exhibiting highly significant standard heterosis for marketable fruit yield per plant and most of its component traits. The cross combinations viz., ARCH-19 (L1) × Solan Bharpur (T1), DARL-10 (L9) × California Wonder (T2) and UHFSP(Y)-11 (L11) × Yolo Wonder (T3) were the top three crosses which exhibited good specific combining ability effects, maximum desirable heterosis and per se performance in respect of marketable fruit yield per plant and number of marketable fruits per plant and can be further exploited for genetic improvement of bell pepper. For all the traits studied, there was preponderance of non-additive gene action which reaffirms the importance of hybrids in bell pepper.
