SUMMARY

Dual purpose barley is an excellent alternate crop for fodder purpose due to its good nutritive value, high palatability and availability of fodder during lean period. Barley crop can be given one cut for green forage and the regenerated crop can be utilized for grain purposes. Thus, barley can serve as supplementary crop for augmenting the green forage demand in the arid/semi-arid areas of northern plains under limited irrigations and in hills under rainfed conditions. The economics goes in favour of dual purpose crop instead of only grain crop in forage scarcity areas of northern plains. The crop can be given one cut at 50-55 DAS in plains and 70-75 DAS in hills for green forage and satisfactory levels of grain yield from the regenerated crop can be utilized as feed or food. On an average, 180-240 and 24-35 q/ha of green fodder and grains, respectively, were produced from dual purpose barley. It responds well to sowing time, fertility levels and time of cutting which vary from location to location. The productivity of green forage as well as grain increased to a significant level by using additional 25 per cent of seed and fertilizer dose as compared to the recommended dose. Seed rate can be enhanced to 125 kg/ha from 100 kg/ha for getting higher productivity of green forage as well as grain and 25 per cent higher fertilizer (75 kg N/ha) should be given after cut for maximising grain productivity. Variety RD 2035 is suitable for dual purpose as it is superior in fodder, grain yield and GEY and to get best performance of dual purpose barley varieties, nitrogen (75 kg N/ha) should be applied in three splits i. e. 1/3 as basal+1/3 immediate after cut+1/3 at next irrigation.

SUMMARY

Sorghum [Sorghum bicolor (Linn.) Moench] is an important cereal crop of the world. This crop is
vulnerable to over 150 insect species from sowing to final harvest. Among the insect pests, the shoot fly (Atherigona soccata Rondani) is one of the most important and destructive pest which causes considerable losses in fodder as well as grain yield. Due to introduction of improved sorghum varieties and hybrids susceptible to this insect and continuous cropping, it has become a principal pest of the sorghum. This pest attacks on the sorghum crop at seedling stage causing maximum damage during the rainy season. The larva of this pest attacks on central whorl of the plant and causes ‘dead heart’ formation. Various methods have been suggested to control this pest. Use of resistant genotypes is the simplest method to control any pest without polluting the environment. A number of genotypes have been screened by various workers depicting resistance against the shoot fly. The sorghum crop grown early or timely can easily escape the incidence of this pest. So, the modification of date of sowing can also prove to be an effective method for management of this pest. The sorghum shoot fly can also be managed by using various types of traps. The fish meal and hanging type traps can be used for catching the adults of this pest. For each insect pest, there is also available parasitoid or predator in the crop ecosystem. Natural enemies also play an important role in reducing the shoot fly population, considerably. Intercropping of sorghum with other crops attractive to this pest can also be used as trap crop to reduce the shoot fly incidence on main crop. The intercropping also enhances the degree of parasitism. The seed treatment and foliar spray of recommended insecticides can also be used for effective management of sorghum shoot fly. Botanicals like neem oil, NSKE, karanj oil, Azadirachtin
etc are also used widely against sorghum shoot fly which can reduce the pest population to a considerable level without causing any harm to non target organisms. The combination of two or more control practices may be used to suppress the sorghum shoot fly population below economic threshold level.

SUMMARY

The foraging behaviour and pollination efficiency of floral visitors on Egyptian clover, Trifolium
alexandrinum was conducted at Forage Section, Department of Genetics and Plant Breeding, CCS, Haryana Agricultural University, Hisar during 2012 and 2013. The maximum foraging rate was recorded in N+P (nectar+pollen) foragers of Apis dorsata (7.2 flowers/min.), P (pollen) forager of Apis florea (7.2) and Apis mellifera (7.1) followed by pollen (6.3), least in nectar forager of A. dorsata (5.1) and A. mellifera (5.5). The maximum foraging speed was recorded in nectar forager A. dorsata (22.4 seconds/flower) followed by its pollen foragers (19.0). The A. mellifera foragers were recorded with minimum foraging speed for nectar+pollen (4.6 seconds/flower), pollen (4.9) and nectar (7.4). The larger bodied A. dorsata carried the maximum loose pollen grains (LPG) on their body (79,625) while the smallest species A. florea had minimum capacity (36,375) and the medium sized A. mellifera was recorded with intermediate capacity (73,250). On the basis of relative pollination efficiency (RPE), A. dorsata was the most efficient pollinators (16.4) of T. alexandrinum flowers followed by the pollen foragers (13.3).

SUMMARY

The F2 segregating population of sorghum [Sorghum bicolor (L.) Moench] of cross HJ 541 (singlecut) × SSG 59-3 (multi-cut) was studied by using simple sequence repeats (SSR) markers to measure genetic divergence within the population. Out of 50 SSR markers, 21 were found to be polymorphic which showed 90.3 per cent polymorphism. Cluster tree analysis grouped the 32 F2 progeny lines into two major clusters : Cluster I comprised three F2 progeny lines with parental genotype, HJ 541, whereas cluster II had the remaining 29 F2 progeny lines with parental genotype, SSG 59-3. Genetic similarity among F2 progeny lines ranged from 0.45 to 0.81 with average similarity of 0.66. Parental genotypes of sorghum were found to be most diverse and F2 progeny lines viz., G2, G18, G20, G21 and G29 showed high similarity with multi-cut parental sorghum genotype, SSG 59-3. Hence, these F2 progeny lines could be selected for early variety development from the F2 segregating population in order to meet ever increasing demand of green fodder for the livestock.

SUMMARY

Sweet sorghums are high energy crops with better growth and yield than fodder sorghums and corn. These are more palatable owing to their sweetness and highly preferred by livestock. Besides, bio-fuel generation these are gaining popularity as fodder crops. Four states released genotypes of sweet sorghum were tested at different levels of nitrogen for green fodder yield and fodder quality. SSV84, CSV19SS, CSV24SS and CSH22SS were grown during kharif 2013 and 2014. The study revealed that CSV19SS performed better than all genotypes tested in terms of green fodder yield at 50 per cent flowering as well as at physiological maturity yielding 41.5 and 44.36 t/ha, respectively. At flowering, the yield responses were only up to 100 kg N/ha. The fodder crude protein per cent was higher at flowering stage (10.05%) compared to physiological maturity (7.96%), while fibre followed a reverse trend. At physiological maturity, the response was 130 kg GFY per kg of N applied at N2, while it was 85 kg per kg N at N3 at maturity. This indicated more N use efficiency at lower N levels and viceversa. Crude protein also increased significantly from 100 to 120 kg N/ha. Among all genotypes tested, CSV19SS proved superior in terms of fodder yield and quality and hence could be utilized as ideal fodder.

SUMMARY

Rust caused by Puccinia substriata var. penicillariae is one of the major diseases affecting both
forage and grain production in pearl millet, particularly in the post-rainy cool season (rabi) crop. Attempt was made to find out the effect of rust of pearl millet on HHB 197, HHB 223 and HHB 197 at three different dates of sowing. Rust appearance in HHB 223 was more in comparison to HHB 197 and HHB 67 Imp. The per cent rust severity was more at recommended date of sowing in comparison to early sown and late sown crop. AUDPC was more in HHB 223 corroborating with HHB 197 but less in HHB 67 Imp. There was drastic change in apparent infection rate with adjustment in date of sowing and apparent infection rate was variable at different stages. Rust development was in progression phase when mean temperature ranged between 21°C to 28°C.

SUMMARY

In view of the increasing demand for fodder, there is urgent need to maximize fodder production
within the existing cropping systems. With this objective a field experiment was carried out in temperate environment during rabi seasons of 2009-10 and 2010-11 on silty clay loam soil to determine the impact of different sowing dates, fertility levels and cutting managements on growth, yield and quality of fodder oat. The treatments comprised of three sowing dates viz. 20 September., 30 September and 10 October; three fertility levels viz., 150:70:40, 125:60:30 and 100:50:20 kg N:P2O5:K2O kg/ha and two cutting management viz., single cut at 50% flowering and double cut on 15 December and 50% flowering stage. Late sowing resulted in poor crop growth and reduced green fodder yield to the tune of 42%. Green fodder yield (36.2 t/ha) and nutrient uptake were higher with the application of 150:70:40 N:P2O5:K2O kg/ha. Double cutting practice produced more green fodder yield to the tune of 15.6 % over single cut crop.

SUMMARY

The field experiment was carried out to study the chemical changes in different organic wastes
during vermicomposting with time interval in rainy season in CCS Haryana agriculture university, Hisar during 2011-12. The agricultural wastes like wheat straw, millet straw, pulse brawn and mustard straw were used as substrates for vermicomposting. The earthworm Eisenia fetida was found most useful for conversion of vermicompost so Eisenia fetida was used in preparation of vermicompost. In vermicompost process, several physical, chemical and the biological reactions took place resulting in changes in the organic matter in a certain period of time. Vermicomposting allowed obtaining organic sources of nutrients which were physically, nutritionally and biochemically improved over composts. In the present studies increased the nutrient content in vermicompost so as changes in nitrogen, potassium, phosphorus (NPK) were studied in different agricultural wastes with time.

SUMMARY

A field experiment was conducted on clay loam soils of the Instructional Farm, Rajasthan College
of Agriculture, Udaipur (Rajasthan) to study the effect of fertility levels viz., 50 per cent recommended dose of fertilizer (RDF), 75 per cent RDF, 100 per cent RDF (80 kg N + 40 kg P2O5 + 40 kg K2O ha-1) and 125 per cent RDF on quality of single-cut forage sorghum genotypes (SPH 1752, CSH 13, PC 1080, SPV 2185, CSV 20 and CSV 23) during kharif season of 2015. Single-cut forage sorghum genotype SPH 1752 synthesized significantly higher chlorophyll content in leaves as compared to rest of genotypes under study. The lower HCN content in green forage was recorded in genotype PC 1080 as compared to rest of the genotypes. Genotype SPH 1752 exhibited maximum crude protein, crude fibre and ether extract content. While concentration of mineral ash was maximum in genotype CSH 13. The genotype PC 1080 and CSV 20 recorded highest concentration of nitrogen free extract and total digestible nutrient in fodder, respectively. Genotype SPH 1752 proved significantly superior in respect to crude protein, crude fibre, mineral ash, ether extract, nitrogen free extract and total digestible nutrient uptake in dry fodder. The crop fertilized with 125 per cent RDF recorded highest chlorophyll content and HCN content in green fodder. This fertility level significantly increased content and uptake of crude protein, crude fibre, mineral ash and ether extract over lower fertility levels. Increasing fertility levels caused significant reduction in nitrogen free extract and total digestible nutrient content in dry fodder which were highest in 50 per cent RDF but application of 125 per cent RDF significantly increased uptake of nitrogen free extract and total digestible nutrient uptake by dry fodder.
