SUMMARY

Fodder crops quality depends on the toxic substances present in it. The three main toxic substances viz. nitrate, oxalate and HCN are most important and are present in different fodder crops and the appropriate agronomic management strategies which have the potential to increase the green fodder yield also has the potential to improve the fodder quality by influencing these most common toxic elements. The influence of agronomy on these negative impact nutrients in various fodder have been discussed. The fertilization application of nitrogen in split doses provides better nutrient distribution and reduces the potential for nitrate toxicity whereas the increase nitrogen application and unirrigated conditions resulted in increase in nitrate but well under toxic level. The form of fertilization also alters the antinutrients levels such as FYM with phosphate fertilizer resulted in lower nitrate content in berseem. Sowing time showed variation in oxalate level in Napier Bajra hybrid. Similarly, sowing of sorghum in also influenced the HCN production. Therefore, the agronomy is found to be the key to improve forage quality by changing content of antinutrients along with yield by adopting appropriate agronomic practices from seed sowing till harvesting.

SUMMARY

Thirty genotypes of fodder cowpea were evaluated in field during the kharif season of 2016 for fourteen characters at College of Agriculture, Kerala Agricultural University, Vellayani, Kerala, India. Based on D₂ analysis, these genotypes were grouped into eleven clusters. Cluster analysis revealed that cluster I (10 genotypes) and cluster II (5 genotypes) were the largest groups, followed by cluster III (4 genotypes) and cluster IV (4 genotypes). All other clusters from cluster V to cluster XI had only one genotype each. The maximum intra-cluster D₂ value was shown by cluster IV (146.57), followed by cluster I (127.52), cluster II (101.49) and cluster III (55.47). Highest inter-cluster D2 values among genotypes existed between cluster VIII and cluster X (1559.98), followed by cluster VIII and cluster XI (1480.33), cluster VIII and cluster II (1367.65), and cluster VIII and cluster IV (1309.08). Minimum inter-cluster D₂ values among genotypes existed between cluster XI and cluster IX (160.10) followed by cluster I and cluster III (164.51), cluster XI and cluster IV (167.47). The analysis clearly shows the existence of significant difference between the 3o genotypes under study for the 14 characters. Hence selection of suitable parents for further breeding programmes based on the requirement can be done from the available gene pool.

SUMMARY

Sorghum is the important cereal crop with multiple uses like food, feed, fodder, fuel and medicines etc. Hence exploration of existing variability in sorghum and its proper utilization for trait specific breeding is essential for sorghum improvement. In the present investigation, sixty one mini core of sorghum were screened for genetic diversity for 30 traits including quantitative and qualitative, out of which except leaf breadth all traits were contributing to variability were selected for genetic diversity analysis. By using hierarchical cluster analysis, the 40 accessions were grouped under 6 clusters. Cluster I contained maximum number of accessions and cluster VI contained the minimum. The maximum inter-cluster distance was observed between cluster VI and cluster IV. Cluster III had the highest mean value for hundred-seed weight and yield. Thus the selection of parents must be based on the wider inter-cluster distance and superior mean performance for yield and yield attributing traits. Therefore present investigation was planned to exploit the existence of a wide genetic diversity present in quantitative and qualitative traits in sorghum accessions which can be further used for sorghum genetic improvement.

SUMMARY

Sorghum germplasm including TNAU released varieties, dual purpose sorghum, forage sorghum, sweet sorghum, Maldhandi collections, ICRISAT lines and Tamil Nadu Local land races were evaluated for forage traits during the rabi 2016 to study the divergence using multivariate (D₂) analysis. Results revealed four distinct cluster indicates that the germplasm had variation between group of cluster. The intra-cluster distances in all the four clusters were registered low, indicating that the genotypes within the same cluster were closely related for its forage value. The highest inter-cluster distance was observed between cluster I (14 genotypes) and cluster IV (2 genotypes) and the lowest between the cluster II (25 genotypes) and III (85 genotypes). The clustering pattern revealed that genetic diversity was not necessarily correlated with geographical origins but depends on forage traits viz., plant height, leaf area index, leaf area and stem thickness. The grouping of accessions into different clusters describes the breeder to identify and select the diverse genotypes, which can be used as the donor parents in breeding programme to realize heterosis. Intercrossing of divergent groups leads to wide genetic base in the base population and greater opportunities for crossing over to occur, which releases hidden variability by breaking the close linkages.

SUMMARY

The present investigation was carried out to evaluate 118 mutant oats including three checks JO-1, JO 03-91 and Kent for association among traits and to judge the direct and indirect effect of
various yield and its attributing traits in pooled of M4 and M5 generation. The study were conducted during Rabi season 2016-17 and Rabi 2017-18 under All India Coordinated Research Project on Forage Crops, Seed Breeding Farm, JNKVV, Jabalpur. Data obtained for correlation and path studies suggested the most important traits observed among the mutant lines were dry matter yield per plant per day, thousand seed weight, plant height hence, direct selection may be effective for the improvement of these characters because these traits had highly significant and positive correlation along with direct positive effect with dry matter yield per plant. Whereas, the characters crude protein yield per plant, crude protein yield per plant per day and panicle weight were also found important as, indirect selection through such traits may be effective in yield improvement as the correlation is mainly due to indirect effects of the character through other component trait. Moreover, these traits can be considered for
formulating plant ideotype and selection based on these characters shall be rewarding for higher yield.

SUMMARY

Evaluation of 60 Guinea grass genotypes collected from various sources was carried out. Observations were recorded on plant height, number of tillers per plant, number of leaves per plant, leaf weight, leaf stem ratio, green fodder yield per plant and dry matter content along with quality traits such as crude protein content, crude fibre content, crude fat content of the grass and analyzed statistically. Among the genotypes, GGLC 12, GGLC 19, FD 679 and GGLC 1 were recorded the highest mean value of fodder yield and crude protein content. Correlation analysis revealed that green fodder yield per plant was positively and significantly correlated with number of tillers per plant, number of leaves per plant, leaf weight and dry matter content. owever negative association was observed with crude fibre content, crude fat content. Hence selecting Guinea grass genotypes with more number of tillers per plant, number of leaves per plant, leaf weight and crude protein content will help to improve fodder yield and quality. On account of this per se performance and trait association it has been found that genotypes GGLC 12, GGLC 19, FD 679 and GGLC 1 were potential genotypes for yield and quality.

SUMMARY

A field experiment was conducted at Forage Research Farm, Dept. of Genetics and Plant breeding, CCS Haryana Agricultural University, Hisar (Haryana) during winter season (rabi) of 2017-18 to study the response of different phosphorus levels on the yield and quality of berseem (Trifolium alexandrinum L.) genotypes. The experiment was laid out in split plot design with five promising berseem genotypes (JB-05-9, PC-82, Wardan, Mescavi and Bundel Berseem-2) in main plot and three phosphorus levels in sub plot (60, 80 and 100 kg P2O5/ha) and replicated thrice. Maximum number of tillers/ft2 was recorded in Wardan which was at par with all entries except Bundel Berseem-2. Highest total green fodder and dry matter yield (687 and 93 q/ha, respectively) were recorded in variety JB-05-9 which was at par with all berseem varieties except Bundel Berseem-2. Maximum B: C ratio (1.37) was also observed in JB-05-9 followed by Wardan. Among different levels of phosphorus, highest green
fodder yield, dry matter yield, average number of tillers/ft2 and plant height were recorded with the application of 100 kg P₂O₅/ha which were found at par with 80 kg P₂O₅/ha but significantly superior to 60 kg P₂O₅/ha. Highest crude protein content (21.96%) was also estimated with 100 kg P₂O₅/ha which was significantly superior over the lower levels of phosphorus (60 and 80 kg P₂O₅/ha). Similar trend was also observed in crude protein yield. B: C ratio was found to be highest (1.38) with 100 kg P₂O₅/ha followed by 80 kg P₂O₅/ha.

SUMMARY

Cluster bean [Cyamopsis tetragonoloba (L.) Taub.] is an important industrial crop of India. India leads the world in its area and production with 82 and 80 per cent of its global area and production, respectively. Among the various soil borne diseases, dry root rot disease causes heavy losses every year especially in arid and semi-arid regions. The dry root rot fungus Rhizoctonia bataticola was isolated from root rot infected cluster bean plant collected from the cluster bean field of Forage Section, CCSHAU Hisar. A measured amount of fungus suspension was mixed in the upper layer of sterilized soil and covered with a thin layer of sterilized soil for its establishment. Cluster bean seeds were sown at the rate of 10 seeds/pot after two days of inoculation of fungus. Four different fungicides viz., Bavistin, Captan, Thiram and Captan + Hexaconazole (a formulation with a mixture of two fungicide) were used as seed dressing at a dose of 2.0g/kg seed. A minimum disease incidence of 33.3 and 39.9 per cent was recorded when the seeds were coated with bavistin followed by captan+hexaconazole as compared to the highest incidence of 66.7 per cent in cluster bean cv. HG-365 in control pots. Soil incorporation of six organic amendments viz. neem cake, mustard cake, cotton cake and vermicompost at a dose of 2g/kg soil, poultry manure and mushroom spent compost at a dose of 5g/kg soil were tested individually against R. bataticola on cluster bean cv. HG 365. A minimum disease incidence of 36.9 and 39.9 per cent was recorded when the soils were incorporated with mustard cake followed by cotton cake. The effect of soil application of Glomus fasciculatum (VAM) at a dose of 400, 500, 600 sporocarps/kg soil were evalvated against R. bataticola. A maximum of 40 percent disease control was recorded when the soils were incorporated with VAM 600 sporocarps/kg soil followed by 25 per cent when soils were incorporated with 500 sporocarps/kg soil and a least disease control of 10 per cent was achieved at 400 sporocarps/kg soil. The effect of soil application of Trichoderma viride at a dose of 5g and 10g /kg soil was tested for the dry root rot disease management. A maximum of 34.8 per cent plant disease control was recorded when the soils were incorporated with T. viride at the rate of 10g/kg soil, whereas, the disease control was 25.1 per cent at 5g/kg soil.

SUMMARY

A field experiment was conducted at CCS Haryana Agricultural University, Hisar (Haryana) during winter season (rabi) of 2014-15 to study the performance of dual purpose oat, wheat and barley under different cutting management system. Three crops viz. oat, wheat and barley and four cutting management viz. no cutting, cutting for fodder at 50, 60 and 70 days after sowing (DAS) were replicated thrice under split plot design. The varieties used were HJ 8, WH 1164 and RD 2035 for oat, wheat and barley, respectively. The soil of the experimental field was sandy loam in texture with pH 8.6, organic carbon 0.49%, available phosphorus 14.0 kg/ha and available potassium 254.0 kg/ha. Among crops, oat produced the maximum green fodder, dry matter followed by barley. However, wheat produced the maximum grain yield followed by barley. Among different cutting management practices, maximum green fodder and dry matter yield were recorded when cut was taken 70 DAS and then left for grain. Wheat crop produced the highest grain and second highest straw yield and thereby fetched highest B:C ratio (2.16). Based on the results, it could be concluded that among the crops viz. oat, barley and wheat, all the three crops suits for dual purpose but crop selection should be based on the priority of end user. If the priority was to get more green fodder from first cut then oat could be first choice followed by barley and wheat. Besides this, the cutting management schedule needs to be standardized. The green fodder yield increased significantly as the number of days to cut increased from 50 to 70 from sowing. But the grain yield decreased significantly as the cutting schedule was advanced from 50 days onward. Based on the economic analysis, wheat was the most remunerative crop followed by oat for dual purpose. If compared with no cut where remunerations were highest, the cut at 50 DAS was most beneficial.
