In the present study, two A CMS lines, ICMA 03333 and ICMA 01777 were crossed with 15 different 5 viz.maintainers having high biomass during 2016. The thirty male sterile F s were crossed with two highkharif1biomass pollinators, Giant Bajra and RBC-2 during 2017 to generate three-way hybrids. A total of viz.Kharifsixty, three-way hybrids were evaluated in summer (Environment I) and (Environment II) for agronomic kharif traits, plant height (cm), green fodder yield (kg/plot) and dry fodder yield (kg/plot) and quality traits, dry viz.viz.matter (%), dry matter digestibility (%) and crude protein (%) during 2018. Significant variability In vitrokharifwas present in parents and hybrids for a majority of the traits under both environments. The pooled analysis of variance over environments revealed that combining ability varies with the change in environments. The lines ICMA 01777 × PB 111B and the tester Giant Bajra were identified as good general combiners for green fodder yield and its component characters as well as for quality traits, under both environments. The three-way hybrids, (ICMA01777 × PB220B) × GB, (ICMA01777 × ICMB97111) × GB, (ICMA01777 × PB111B) × GB, viz. and (ICMA01777 × ICMB00444) × GB were found to be promising cross combinations for almost all the traits under study. The high SCA cross combinations also showed high heterotic effects. Additive gene action was predominant in the inheritance of yield traits, whereas for fodder quality traits non-additive gene action was predominant

The present experiment comprised of 46 cowpea genotypes to estimate genetic variability, interrelation among 13 quantitative characters and genetic divergence during 2020. High heritability coupled with highKharifgenetic advance as of mean was observed for the characters , seed yield per plant, number of per centviz.clusters per plant, number of pods per plant, plant height, days to 50% flowering and days to maturity. High phenotypic and genotypic coefficient of variation, heritability and high genetic advance as of mean per cent(GAM) were observed in seed yield per plant, number of clusters per plant, number of pods per plant and plant height. Seed yield per plant was found positively and significantly correlated with pods per plant, seeds per pod, pods per cluster, pod length and 100 seed weight. Path analysis revealed that number of seeds per pod, number of pods per plant and 100 seed weight would be selected as important towards seed yield charactersas they showed a high positive direct effect on seed yield. D analysis revealed that all the genotypes were 2grouped into seven distinct clusters. Cluster V had the maximum intra-cluster distance. The crossing among the genotypes of clusters V and VII, II and V, III and VI would result in novel recombinants as they showed high inter-cluster distance. Increased contribution to the divergence was found for the characters like plant height, seed yield per plant, number of clusters per plant and days to 50% flowering. Cluster V was found to be best performing for agronomic characters, followed by Cluster VI and Cluster III. Cluster II was best performing for nutritional value and earliness
本试验由 46 个豇豆基因型组成，旨在评估 2020 年期间的遗传变异、13 个数量特征之间的相互关系以及遗传差异。在单株种子产量、单株穗粒数、单株荚果数、株高、50%开花天数和成熟天数等特征方面，观察到了高遗传率和高哈里夫期平均遗传进展。单株种子产量、单株穗数、单株荚数和株高的表型和基因型变异系数、遗传率和平均遗传进展（GAM）均较高。每株种子产量与每株豆荚数、每荚种子数、每簇豆荚数、豆荚长度和 100 粒种子重量呈显著正相关。路径分析显示，每荚种子数、每株荚果数和 100 粒种子重量对种子产量有很高的直接正向影响，因此被选为种子产量的重要特征。D 分析表明，所有基因型被分成 7 个不同的群。簇 V 的簇内距离最大。第 V 组和第 VII 组、第 II 组和第 V 组、第 III 组和第 VI 组的基因型杂交会产生新的重组体，因为它们的组间距离较大。在株高、单株种子产量、单株穗数和 50%开花天数等特征方面，差异的贡献增大。簇 V 的农艺性状表现最好，其次是簇 VI 和簇 III。第 II 组在营养价值和早熟性方面表现最好。

This study was conducted to determine the vegetation-covered area, botanical composition, yield, quality, capacity, condition and health of seven lowland pastures in Bingol province, Turkey. Thirty-three plant species were identified during the study. Twenty-nine of these species were found to be invaders, two were increasers, and two were decreasers. The most common species in the pastures were , Trifolium repens Eremopoa persica, Poabulbosa and The rate of the vegetation-covered area of the pastures was Gundelਟa tournefortਟਟ.determined to be 97.4%, the rate of legumes in the botanical composition was 32.7%, the rate of grasses was 50.0% and the rate of other family plants was 17.3%. The average of pastures had plant height of 24.2 cm, green fodder yield of 5820 kg/ha, dry matter yield of 1290 kg/ha, crude protein content of 19.5%, acid detergent fiber (ADF) content of 29.1%, neutral detergent fiber (NDF) content of 44.4%, P content of 0.37%, K content of 2.55%, Ca content of 1.30% and Mg content of 0.33%. It was found that the capacity of the pastures varied between 3.3 and 88.5 animal units (AU), with an average of 32.2 AU. In evaluating the condition of the pastures, it was found that 4 pastures were classified as 'medium-healthy' and 3 pastures were classified as 'good-healthy'. It was concluded that appropriate grazing systems should be applied to lowland pastures and that current yield and quality can be increased through fertilization.

There are number of hybrids and composites in maize which are used for silage making by farmers. The objective of the present study was to find out the promising high yielding and better-quality silage cultivar. A study was undertaken during, 2019-20 and 2020 in randomized block design (RBD) with three Rabi Kharif replications consisting of 13 maize hybrids and three composites. The African Tall recorded significantly higher plant height (333.39 cm), number of leaves/plant (13.83) and green fodder yield (51.92 t/ha) compared to all other hybrids and composites. While dry matter yield was higher in maize hybrids, P 3401(16.85 t/ha) followed by DMRH 1410 (15.45 t/ha). Crude protein yield (1.09 t/ha) was also higher in P 3401 followed by PMC 6 and P 3396 (1.01 t/ha). The pH of silage in all maize genotypes was in acceptable range. NDF content varied from 49.48 to 55.11% and 53.19 to 59.39% in green fodder and silage stage, respectively. ADF content varied between 24.45 to 28.55% in green fodder and 28.74 to 33.34% in silage. But difference was found non-significant for both NDF and ADF in silage and green fodder. Based on this study African Tall, P 3401 and ,DMRH 1410 were identified as promising maize genotypes for higher biomass yield and quality silage preparation for ruminant animals

An on-farm study was conducted to record the role of traditional livestock feeding practices, particularly the role of tree leaves in fulfilling the fodder requirement of dairy animals in 'low-input and low-output' systems of sub mountainous zone of Indian Punjab. Findings of the study were based on primary data of mixed farms equally spread over different farm size groups sub-mountainous zoneof randomly selected district Hoshiarpur from of Punjab state. The study highlighted that the supplementation of tree leaves in addition to cultivated fodder helped the small and medium farmers to attain the adequacy of green fodder. During the summer season, tree leaves, on an average, improved the green forage DM availability at small farms by 128.0% (1.89 to 4.31 kg/d/ACU) and at medium farms by 70.6% (2.69 to 4.59 kg/d/ACU). In the winter season, the corresponding percentage for small and medium farms stood at 112.8 and 76.0%, respectively. The study further enunciated that fodder utilization/ACU on fresh basis was statistically higher in large farms, while in terms of dry matter (DM), fodder utilization was statistically at par for all selected landholding categories. Following the traditional practice of supplementing tree leaves with cultivated fodder (scenario 2), the proportion of farms (irrespective of size) with adequate fodder was recorded at 62.2% in summer season and 88.9% in winter season in comparison to 26.7 and 40.0% in hypothetical case of relying only on cultivated fodders (scenario 1).

Ecofriendly strategies for the management of sorghum shoot fly, helps in addressing the Atherigona soccataissues related to insecticides load on forage crop. The present study was carried out to know the suitable date of sowing on damage indices of sorghum shoot fly and green fodder yield in sorghum. The staggered sowing technique at a different time intervals was used, starting from 2 fortnight of March (12 SMW) to 1 fortnight of ndthstJuly (27 SMW). Oviposition in terms of eggs per 10 plants and dead heart percentage was recorded to be low thin 18 SMW (1 fortnight of May) sown crop (eggs: 6.66 and dead heart: 25.46%), but it was found to be highest thstin 1 fortnight of July (27 SMW) sown crop (eggs: 21.95 and dead heart: 65.45%). The correlation of shoot fly stthinfestation in relation to weather parameters revealed that egg load and dead hearts were negatively correlated with maximum temperature and positively correlated with minimum temperature, relative humidity and rain fall. Green fodder yield was recorded to be highest and lowest for the crop sown on 18 SMW (409 q/ha) and 27 ththSMW (302 q/ha), respectively. The study indicated that 1 fortnight of May was the best time to escape from the stsorghum shoot fly attack.

The study indicated that 1 fortnight of May was the best time to escape from the stsorghum shoot fly attack.","PeriodicalId":49636,"journal":{"name":"Range Management and Agroforestry","volume":"7 1","pages":""},"PeriodicalIF":0.8,"publicationDate":"2023-12-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139168186","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Oat (Avena sativa L.) is an important rabi cereal fodder crop of north-west India. Recently, a number of fodder oat varieties have been released in country-wide adaptability. However, limited information on optimal row spacing and seed rate for these fodder oat varieties in seed production system is available especially in the north-western parts of the country, where it is primarily grown for fodder purpose. Hence, field experiments were conducted during winter season from 2016-17 to 2019-20 to evaluate the effects of row spacing and seed rate on growth, yield attributes and seed yield of two fodder oat varieties. When averaged across years, there was 10.4% increase in oat seed yield with 30 cm row spacing over 20 cm row spacing. Higher oat seed yield in wide rows during all the years of the study was mainly attributed to more number of effective tillers, seed per panicle and panicle length. The 1000-seed weight, however, remained unaffected by the row spacing. An increase in seed rate from 37.5 to 62.5 kg/ha resulted in a decrease in seed yield and various yield attributes. However, there was no significant interaction between row spacing and seed rate for seed yields. In conclusion, for reaping maximum oat seed yield, the fodder oat varieties should be planted at 30 cm row spacing and with 37.5 kg/ha seed rate

A study was conducted to evaluate the impact of organic and conventional production system on fodder cowpea growth and soil health. This study was conducted in a farmers field of Erode, Tamil Nadu in a randomized block design with three replications. For the study, six farmers' fields involving organic (ORG) practices and one conventional (CON) production system were selected. Soil and plant samples were collected at the time of harvest and analyzed for growth, and soil health parameters. The results revealed that significant differences were found in the growth parameters of fodder cowpea among the organic and conventional production system. The analyzed chemical properties ., soil reaction, electrical conductivity viz(EC), macro nutrients, and biological indicators ., soil organic carbon (SOC), organic matter (SOM), vizmicrobial biomass carbon (MBC), culturable microbes, and yield were found to be higher in organically managed soils than the conventional farming method

This study examined various shrub species integrated into field crops (wheat, vetch, barley), including leguminous varieties (), species (Medicago arborea, Colutea istria, Coronilla glauca AtriplexA. canescens, A. nummularia, A. undulataOpuntia ficus-indica), and . It assessed their suitability based on forage production, quality, direct browsing, seasonal suitability for direct browsing and soil fertility. species demonstrated Atriplexhigher suitability indexes. While leguminous species enhanced soil nutrient status, their low initial biomass productivity limited suitability for livestock forage. , with a lower suitability index, was Opuntia ficus-indicadeemed unsuitable for direct browsing, as it was primarily a cut-and-carry crop. Therefore, the successful implementation of alley cropping systems requires a careful balance and analysis of shrub species that not only provide ample forage biomass support but also direct browsing and contribute to enhanced soil conditions for crop growth. This approach holds promise for sustainable and productive farming practices
