SUMMARY

A field experiment was conducted as Fodder Section Farm of Department of Crop Improvement, CSK HPKV, Palampur during 2015-27 to estimate the direct and indirect effects of twelve morphophysiological traits towards fresh fodder yield in F2, F3 and F4 generations of oat cross PLP-1 x HJ-8 which revealed that tillers per plant, leaves per plant, dry matter yield per plant and crude protein yield per plant plays chief role as major forage yield component in both early and late generations, therefore selection of these traits would offer the scope for improvement in fresh fodder yield and also the significant correlation between these traits in F2, F3, and F4 generations indicated that these traits are mostly governed by additive gene action and also the suitability of these traits for selection on individual plant basis in the advanced generations of segregating populations which would ultimately help to achieve higher total green fodder yield in oats. In the evaluation of F2, F3 and F4 generations along with parents, about 14.33, 18.44, and 22.89% transgressive segregants, respectively, were obtained for most of the traits which indicated the importance of PLP-1 and HJ-8 as parents in the future breeding programme for improving fodder yield in oats.

SUMMARY

The field experiment was conducted during the rabi season of 2016-17 at the Forage Research Farm of Chaudhary Charan Singh Haryana Agricultural University, Hisar with the objective to study the effect of cutting management and phosphorus fertilization on forage and seed productionof multicut oat. Treatment combinations comprised of eight cutting management treatments i.e. C1 (Seed to Seed), C2 (Fodder at 50% flowering), C3 (Fodder 60 DAS- Seed), C4 (Fodder 70 DAS- Seed), C5 (Fodder at 80 DAS- Seed), C6 (Fodder 60 DAS- Fodder at 50% flowering), C7 (Fodder at 70 DAS- Fodder at 50% flowering), C8 (Fodder 80 DAS- Fodder at 50% flowering) and four levels of phosphorus i.e. 0, 20, 40 and 60 kg P2O5/ha. The experiment was laid out in split plot design and replicated thrice. The soil of the experimental field low in available nitrogen (161 kg N/ha), medium in available phosphorus (12 kg/ha) and available potassium(252 kg/ha, slightly alkaline in reaction (pH 7.8). The results indicated that the highest green fodder and dry matter yield was obtained when only one cut of fodder was taken at 50% flowering stage and it was statistically at par for green fodder yield with treatment where first cut for fodder was taken at 80 DAS and second cut at 50% flowering stage. Harvesting of fodder at 80 DAS gave significantly higher forage yield and seed yield than the harvesting at 60 or 70 DAS. Contrary to this, the straw yield and biological yield were significantly higher in the treatment when the crop was raised purely for seed purpose. Under dual system, delay in first cut i.e. from 60 to 80 DAS resulted in a significant increase in fodder and seed yield over the earlier cuttings. Every incremental dose of applied phosphorus upto 40 kg P2O5/ha resulted in a significant improvement in forage, seed and straw yield over the lower doses.

SUMMARY

A field experiment was couducted during summer-kharif, 2013 at Sorghum Research Station, Deesa to study the heterosis for fodder yield and quality traits in forage sorghum. Analysis of variance in individual environment as well as on pooled basis revealed highly significant differences among genotypes, parents and hybrids for all the traits. The heterosis was evident for green fodder yield per plant and other important yield contributing traits from the significance of mean squares due to parents vs. hybrids in individual as well as pooled over environments for almost all the traits. Significance of mean squares due to genotypes x environments, parents x environments and hybrids x environments for most of the traits indicated that genotypes, parents and hybrids performed differently in different environments. The analysis also revealed highly significant differences for mean squares due to parents vs. hybrids x environments for all the traits except brix per cent, HCN content and crude protein content. The magnitude of heterosis was high for green fodder yield per plant, dry fodder yield per plant, brix per cent and leaf : stem ratio, medium for plant height, stem diameter, number of leaves per plant, leaf length, leaf width, shoot fly dead heart per centage and HCN content and low for days to flowering and crude protein content. The best five hybrids on the basis of standard heterosis were 27A x SRF 317 (39.79 %), 14A x SRF 332 (38.76 %), 104A x SPV 2113 (35.77 %), 9A x SPV 2113 (34.81 %) and 14A x SRF 335 (29.26 %) for green fodder yield per plant. These hybrids also exhibited high heterosis for one or two of its contributing traits, thereby these top hybrids can be exploited commercially for fodder yield after testing in wide range of environments.

SUMMARY

Efforts were made to study the pattern of diversity in 40 genotypes of six rowed barley (Hordeum vulgare L.) using the principal component method of factor analysis. First five principal components had eigen values more than one and have explained altogether 81.37 % of the total variation in 10 metric traits which were mainly associated with plant height, 1000-grain weight and biological yield; days to heading and maturity; harvest index and grain yield; spike length and number of grains per spike; and number of tillers per meter row. The remaining principal components made very little contribution towards total variation and thus could not be considered of much practical value to barley improvement. The genotypes BH 946, BH 15-02, BH 16-40, BH 16-44, BH 10-11, BH 15-06 and BH 15-07 were found to have high yield potential. The results of the present study provide evidence of diversity in barley and thus prove the adequacy of the principal component method in biological investigations.

SUMMARY

Hydroponic fodder production plays significant role in augmenting fodder shortage of small holder dairy production system in scarce rainfall areas. The present experiment was conducted in the adopted villages of Krishi Vigyan Kendra, Yagantipalle, Kurnool dist., A.P. to assess the effect of hydroponic maize fodder (HMF) on production performance in the milch buffaloes. A low cost hydroponic fodder production devise (Krishi Fodder Master) was fabricated and utilized in the experiment. Twenty graded murrah buffaloes of 2nd and 3rd lactation were equally divided into two groups (T1&T2). First group fed with 5kg sorghum straw per day along with recommended quantity of concentrates and the second group fed with 5kg sorghum straw and 12kg HMF per day. Data on HMF production, milk yield/ day, % fat in milk and 3.5% FCM/day was collected for 60 days trial period. 7.2kg HMF was obtained from one kilogram of maize seed within 7 days without using any nutrients in the irrigated water. The DM, CP, CF, EE, TA and NFE contents in HMF were 14.3 15.8, 12.62, 3.74, 3.27 and 64.57 respectively. The data revealed that 6.5% increased mean milk yield/day was recorded in T2 (6.88±0.47) as compared to T1 (6.46±0.49). The mean % fat and SNF in T1 and T2 were recorded as 6.78±0.19, 8.86±0.16 and 7.08±0.23, 9.14±0.12 respectively. The gross income per day was 13.05% more in T2 (Rs.250.47±17.31) than T1 (Rs.221.55±15.49). The data revealed that saving of Rs.15.61/buffalo/day on concentrate feeding and increased net returns of Rs. 44.58/buffalo/day were recorded on supplementing HMF. These results were found significant at 5% (P<0.5). Feeding of HMF to buffaloes produced under Krishi Fodder Master was found to be economical for medium producing animals in low rain fall areas.

SUMMARY

A pot experiment was conducted during the year 2015-16 to evaluate the zinc utilization potential of five pearl millet varieties by exogenously applied micro nutrients (Zn) in the Department of Soil Science and Agricultural Chemistry, Tamil Nadu Agricultural University (TNAU), Coimbatore. Soil application with two levels of zinc (0 and 10 mg/kg) in a Completely Randomized Design was replicated thrice under factorial arrangement (FCRD). Screening of different genotypes in a potentially zinc deficient soil (calcareous soil) gives a picture to identify the nutrient use efficient genotype of pearl millet and further use it to impose biofortification approach through fertilization strategies. Agronomic biofortification increase the concentration of trace mineral elements which efficaciously solve the health related problems in developing areas of the world. Results showed that soil application of Zn at 10 mg / g has significant effect on zinc nutrient concentration in pearl millet crop (pre flowering stage). Application of micronutrients also increased and improved growth parameter. Among the varieties studied CO (Cu) 9, ICTP 8203 and ICMV 221 were found to be responsive but not efficient and varieties collected from local farmers at Madurai and Coimbatore Districts were found to be efficient and non responsive as screened in the preface study through fertilization strategy.

SUMMARY

The present investigation was carried out at Barley Research Area of the Department of Genetics & Plant Breeding, CCS Haryana Agricultural University, Hisar during rabi 2016-17 to study the genetic parameters and character association for 10 quantitative traits in 87 barley genotypes. Significant genotypic differences were observed for all the traits studied indicating considerable amount of variation among material evaluated for each trait. Most of the traits under investigation exhibited wide range except for days to heading and maturity. Phenotypic and genotypic coefficients of variation were highest in number of grains per spike followed by grain yield, harvest index, number of tillers per meter row and 1000grain weight. Estimates of heritability ranged from 61.2 per cent for harvest index to 95.5 per cent for number of grains per spike, while grain yield showed 79 per cent heritability. High heritability coupled with high genetic advance was observed for number of grains per spike, number of tillers per meter row, grain yield, 1000-grain weight and biological yield, indicates the importance of these traits in selection and crop improvement. The genotypic correlation estimates showed significant positive association of grain yield with harvest index, biological yield and number of grains per spike while the characters viz., days to heading and maturity, plant height and ear length exhibited significant negative correlation with grain yield. Harvest index and biological yield exerted the highest positive and significant direct effect on grain yield. Therefore, these characters could be considered as main components for selection in a breeding program for higher grain yield.
