Ricebean has been categorized as underutilized crop despite its nutritive quality and fodder yielding ability benign higher than other legumes of Vigna family. In addition to its nutritive value, this crop is fairly resistant to drought and flood conditions. The purpose of this paper is to provide important traits for direct selection of fodder yielding ricebean genotypes through analysis of phenotypic and genotypic association and path coefficient. In the present study, the degree of association between yield and yield contributing attributes were estimated in 85 germplasm lines for nineteen quantitative traits so that direct selection of the promising traits may be effective for the improvement of yield potential of future genotypes of ricebean. Correlation studies indicated that green fodder yield per plant was significantly and positively associated with green fodder yield per day, number of leaves per plant, number of branches per plant, crude protein yield per plant, crude protein yield per plant per day, dry matter yield per plant, dry matter yield per plant per day, leaf stem ratio and plant height at both genotypic and phenotypic levels. Path coefficient revealed that green fodder yield per plant per day has highest direct effect and significant positive correlation towards yield. Other traits, crude protein yield per plant, dry matter yield per plant per day, days to 50% flowering, days to flower initiation and plant height were also found to be important fodder yield indicators in ricebean.

Lucerne is an important legume forage grown worldwide due to its high nutritive value, yield potential, quality and survival under highly contrasting environments. Estimation of genetic diversity in germplasm is an important criterion in breeding programme and is done based on phenotypic characters, biochemical and molecular markers. Thirty one accessions of Lucerne collected from Maharashtra and Gujarat were evaluated for morphological, yield characters, molecular markers and were compared with national check RL-88. The diversity analysis of morphological and yield characters indicated wide range of variation within the accessions. The accession RLG 08-1 recorded significant differences for plant height, number of tillers per plant, internodal length, green fodder, dry matter and crude protein yield (P 0.05) over RL-88. Green fodder yield was significantly correlated with plant height (0.72**), no. of tillers per plant (0.71**) and internodal length (0.71**). Dry matter yield was found significantly correlated with plant height, no. of tillers per plant, internodal length and crude protein yield (0.70**, 0.69**, 0.70** and 0.99**). Leaf stem ratio was not linearly correlated with green fodder, dry matter and crude protein yield. Principal component analysis (PCA) demonstrated that the first two PCs contributed to 93.7% of total variance among the accessions. The accession RLG 08-1 was found superior among all the accessions. Thirteen Inter Simple Sequence Repeats (ISSRs) markers showed 82.8% polymorphism. The dendrogram revealed slight geographical structuring and RLG 08-1 was found genetically distinct from other accessions.Mantel correlation was not observed between morphological and yield characters as well as molecular markers.

Fourteen genotypes of fodder oat (Avena sativa L.) were evaluated to assess the genetic variability and association analysis during Rabi 2018-19. The character dry matter yield (q/ha/day) had the highest heritability. GCV and PCV estimate was recorded for the days to 50% flowering. Highest genetic advance was observed for green forage yield (q/ha) were as high as percentage of mean was observed for dry matter yield (q/ha/day). In the present experiment, it is evident for the result that day to 50% flowering has a highly significant negative correlation with green forage yield. The highest positive direct effect contributing to green forage yield (q/ha) was due to low crude protein (q/ha). However indirect effect on improvement in green fodder yield was exerted by most of the traits studied. A direct selection for all these traits will help in the improvement of green fodder yield. Green fodder yield was positively correlated with most of the traits studied except days to 50% flowering and plant height (cm). The study provided the opportunity to identify suitable genotypes to be used in a future breeding programme.

Managing N, P and K inputs in semi-natural meadow production systems is important for achieving maximum yields in livestock farming. The objective of the present study was to estimate the effect of different NPK levels (N0P0K0, N50P50K50, N100P50K50, N100P100K100, N150P100K100 and N200P150K150 kg ha-1 yr-1) on the yield, quality and nitrogen nutrition index (NNI) in a grassland community of Agrostietum capillaris (semi-natural meadow) in western Serbia. The study was conducted during the seasons of 2005-2008. The values of the investigated parameters, except for the unit N uptake, were the highest in 2004/2005 due to favorable climate conditions. The levels of nitrogen significantly increased all of the studied parameters compared to the control treatment, except for unit N uptake. Mineral fertilizers at N200P150K150 provided the highest green forage yield (25.12 t ha-1), dry matter yield (8.12 t ha-1), crude protein yield (876.3 kg ha-1), nitrogen uptake (140.2 kg ha-1) and nitrogen nutrition index (70.2%), and the lowest unit N uptake (0.0022 kg N kg DMY-1). The use of mineral fertilizers increased green forage yield, dry matter yield and crude protein yield, increasing fertilizer from lowest to highest rate increased fresh and dry matter yield, as well as protein yield. Based on the results of the study, monitoring of nutrition indices would be necessary in order to increase productivity and economic benefits.

In forage-plants breeding, the selection of superior genotypes has been undertaken through successive harvests in previously established intervals. However, this process involves many steps, the evaluation of many traits, and a great spending with costs and labor. Thus the estimate of the repeatability is essential in improvement of perennials, it allows predicting genotypic value of the individual, the minimum number of evaluations in the selection of genotypes and minimizes resources and time in the selection of promising individuals. The objective of this study was to estimate the repeatability coefficient for morphological traits in elephant grass and determine the number of evaluations needed for phenotypic selection more efficient. The experimental randomized block design with 53 genotypes and two replications. The repeatability coefficients were estimated for variables plant height, number of tillers, stem diameter and dry matter yield, using the methods of Anova, Principal Components and Structural Analysis. We observed significant differences between genotypes (P <0.01) for all variables. The main components provide larger estimates of repeatability when compared to other methods. Estimates of the repeatability coefficients are of high magnitude average for the variables plant height (0.44) number of tillers (0.44) and stem diameter (0.63) and low magnitude for dry matter production (0.27). The Principal Components method requires five, five, two and eleven measurements for plant height, number of tillers, stem diameter and dry matter yield, respectively, with 80% reliability.

1. The effects of the stage of growth and frequency of cutting on the yield and chemical composition of Panicum maximum Jacq., under the tropical humid conditions prevailing in Ibadan area were studied in the season 1953 to 1954. The cutting frequencies adopted were seventeen, eight, six and four times harvesting a year which corresponded respectively to a growing period of 3, 6, 8 and 12 weeks before the plants were cut.2. It was shown that Guinea grass gave the highest growth rate and cumulative green fodder yield (approximately 28 tons per acre) per year when allowed a 12-weekly growth cycle. Cutting the grass every 3 weeks gave a total minimum yield of 20 tons per acre. 6-weekly samplings resulted in higher green fodder yield than cutting it every 8 weeks. Such yield differences which exist among the various cutting treatments, however, are not statistically significant. When yields of edible (leafy) green fodder were considered, the order of superiority was 3-weekly > 6-weekly > 12-weekly > 8-weekly.It was shown that the increased yield of green and dry fodder obtained from the 12-weekly cut grass was made up of both fresh regrowth as well as of grasses which had been growing for 12 weeks.3. P. maximum contains a fairly high percentage of dry matter and this increased directly with the length of cutting intervals. Dry-matter yields, like those of green fodder, were highest for the 12-weekly harvested material, followed in order by the 6-weekly cut, the 8-weekly cut and the 3-weekly cut samples. However, the production of leaves and the accumulation of dry matter in them, are inversely related to the length of growing interval up to and including grasses allowed 8-weekly growing periods.4. The stems of P. maximum tend to mature more rapidly than the leaves, particularly at a growing stage of between 3 and 6 weeks of age. At between the 8 and 12 week growth stages, the development of the stem of P. maximum in relation to that of its leaves was not as rapid as observed in the case of either P. purpureum or of Andropogon tectorum.5. The percentage dry matter, nitrogen-free extract, ether extract and calcium are directly related, while those of crude protein, silica-free ash, phosphorus and magnesium, are inversely related to the length of cutting intervals. It was also shown that the mean percentage crude protein of Guinea grass of about 12 at 3 weeks of growth, declined by 45% to 6·4 when the grass was cut every 12 weeks. The grass contains a high amount of magnesium, a reasonably high amount of calcium, but a somewhat low content of phosphorus, a fact which accounts for the wide calcium to phosphorus ratio. This ratio widened with the length of cutting intervals.6. When Panicum maximum was cut at 3 -weekly intervals, it produced 69·3% more protein, 58·5% more silica-free ash, 32·3% more calcium, 49·6% more phosphoric acid, 71% more magnesium and higher amounts of carbohydrate and total nutrient material than when it was allowed to grow for 8 weeks. Similarly when the grass was allowed a 12-weekly growth cycle, it produced 35% more of total nutrient, 36·5% more of carbohydrate material and 62·2% more of calcium than when it was sampled every 8 weeks. It appears totally unprofitable from the point of view of yield of chemical constituents to subject P. maximum to a growth cycle of 8 weeks.7. Yields of green and dry matter and the percentage crude protein, silica-free ash, and nitrogen-free extract are directly related to the degree of precipitation. In general periods of high rainfall were accompanied by higher yields and percentage content of these constituents, while periods of low rainfall gave rise to smaller yields. The percentage content of crude fibre, on the other hand, was inversely related to rainfall.

There had been very less systemic study of forage crops in this part of the world. The information is scanty and not well documented. With these backgrounds, a field experiment was conducted during winter and summer season of 2012-13 and 2013-14 with three forage crops [Brachiaria brizantha, Panicum maximum and Setaria anceps] and three mulching managements [no mulching, soil dust mulching and live mulching]. Experiment was laid out in split plot design with three replications. Forage crop was assigned to the main plots and mulching to the subplots. The results revealed that superior growth attributes as well as highest green fodder yield (91.14 q ha-1 in winter and 307.20 q ha-1 in summer) and dry matter yield (26.27 q ha-1 in winter and 66.99 q ha-1 in summer) were obtained with forage crop Setaria anceps. Mulching influenced all growth parameters (plant height, leaf area index and crop growth rate) significantly and recorded highest with live mulching followed by soil dust and no mulching. Adoption of live mulching resulted in highest green fodder yield (94.17 q ha-1 in winter and 309.58 q ha-1 in summer) as well as highest dry matter yield (26.28 q ha-1 in winter and 71.93 q ha-1 in summer). The present experimental findings signify the importance of live mulching in improving growth attributes and yield of forage crops.
