    Not AvailableThe investigations on Nectar secretion rhythms and nectar energetics of Trifolium alexandrinum flowers were carried at Forage Section, Department of Genetics and Plant Breeding, CCS, Haryana Agricultural University, Hisar during 2012 and 2013. A T. alexandrinum flower produced a mean dry nectar sugars (DNS) of 1.95 mg and its amount in 2013 was higher (2.168 mg/flower) than 2012 (1.734 mg). Physiologically mature flower (fully opened) produced maximum amount of DNS (2.453 mg) followed by half (1.900) and just opened flowers (1.500 mg). The maximum DNS (2.027 mg) was produced at 1300 h followed by at 1000 and 1600 h (1.926 and 1.900 mg, respectively) which were at par with each other. The fully opened flowers produced maximum DNS at all the observed time intervals of 1000, 1300 and 1600 h (2.468, 2.446 and 2.444 mg/flower, respectively) followed by half opened flowers in the afternoon hours of 1300 and 1600 h (1.947 and 1.921 mg, respectively) while it was lower in the morning hours at 1.832 mgNot Availabl

    Not AvailableQuantification of Egyptian clover Trifolium alexandrinum crop's value as provider of surplus honey and pollen was studied at CCS, Haryana Agricultural University, Hisar during 2012 and 2013. Colony performance parameters like area honey, nectar, pollen, brood, drone and whole bee population showed significantly higher trend during I, III, and IV weeks of May during both the years and declined marginally at end of the flowering.Not Availabl

    Not AvailableA total of 178 rice genotypes from various station and national trials were evaluated for resistance against brown planthopper (BPH) under natural infestation condition during kharif 2011 at CCS HAU, Rice Research Station, Kaul, Kaithal. The results revealed that only 5 genotypes viz., CN 1724-9-4-5, MAUB-181, ACC-451 and IR 79584-38-2-1-9 were resistant, 28 were moderately resistant, 102 moderately susceptible and the rest were susceptible (43) to brown planthopperNot Availabl

    Not AvailableThe 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).Not Availabl

    Not AvailableIn the recent past, with changing rainfall scenario, land degradation as well as scarcity of water has becone a common phenomenon in the dry areas. Runoff management is an important area to be considered while managing the limited resources of soil and water in dry areas. Some important and basic technique have been described in this chapter to manage agriculture land in such areas. These techniques atre especially in relation to rainfall, soil, local cropping practices and mechanism for management of exoess runoff. The principles of runoff management are to minimize the concentrations of runoff volume and slowing the runoff velocity. The choice of appropriate measures depends on soil, topography, climatic and socio-economic considerations. lt is difficult to generalize about applicability of these measures. The sd conservation becomes a critical task for sustainable development for combating further land degradatior and investing in ifuture conservation. The improvement in soil quality along with sequestration of sd organic carbon has tremendous potential for increasing productivity and conserving natural resources. The most appropriate strategy for combating soil erosion and runoff management in dry regions depends upon identifying the influencing key factors and their adoptability in the area.Not Availabl

    Not AvailableGroundwater extraction through electrically operated tubewells offers a resilient source of irrigation supply in arid regions especially during droughts. However, interrupted and low-voltage electric supply with limited availability and frequent trips increases repair and maintenance costs of tubewell irrigation and reduces tubewell discharge resulting in less-efficient and non-uniform water application. This study evaluates performance of an indigenous system of groundwater irrigation that was evolved over the generations in arid region of Gujarat, India to address electricity-triggered issues of irrigated agriculture. In this system, groundwater extracted during electricity availability hours is stored in surface reservoirs for later supplying to irrigate crops under gravity flow irrespective of electricity availability. A comprehensive survey of the indigenous system is conducted in a village of Gujarat to make inventory of all tubewells and storage reservoirs about their depth, size, pump type and horsepower, command area, crops, irrigation timing and frequency, etc. Discharge of tubewells was measured and their locations were recorded. Results revealed that the indigenous system is advantageous over the direct tubewell-irrigation in terms of 37.4% higher water-delivery rate and 50% more average irrigation capacity. These findings prove adequacy of the indigenous system in regulating irrigation supplies to deal with electricity-induced intricacies of irrigated agriculture. Amount of water lost through unit area of earthen (seepage and evaporation ∼2.77 m) and masonry (evaporation ∼1.22 m) reservoirs collectively accounts for a negligible proportion (0.9%) of groundwater draft. Furthermore, a methodology is devised to precisely estimate village-level groundwater draft for irrigation, which is validated by 0.9% deviation between observed and predicted values of groundwater draft. Moreover, the indigenous system is simple, cost-effective and easy to implement in other parts of the world especially in arid regions of the developing countries where low-voltage and intermitted electricity supply persists.Not Availabl
