Abstract

Epizootic ulcerative syndrome (EUS), a disease listed by World Organisation for Animal Health (OIE) has been reported in 26 countries across 4 continents. Till date, 94 fish species have been found to be naturally infected with EUS and its host range is gradually expanding. In the year 2010-11, outbreaks resulting in heavy fish mortality were recorded in wetland districts of Uttar Pradesh, India, and EUS was confirmed as the cause of mortality on the basis of histopathology, isolation of Aphanomyces invadans, bioassay and PCR. A prevalence of ∼69% (371/540) was recorded and 13 fish species were found to be infected. Interestingly, EUS was observed in seven new species (Aristichthys nobilis, Channa punctatus, Wallago attu, Mastacembelus armatus, Mystus cavasius, Anabas testudineus and Puntius conchonius) for the first time in natural outbreaks. Furthermore, the disease was observed even in the month of May when the mean water temperature was 31.6±0.65°C. This suggests that the disease can result in severe losses even after two decades of its emergence.

Abstract

Field experiment was carried out during Kharif 2005 and 2006 using different herbicides to study the response of weed control treatments in maize and cowpea intercropping system for quality fodder. Pre-emergence application of alachlor, metolachlor and pendimethalin @ 1.00 and 1.50 kg a.i./ha each and post emergence application of imazethapyr @ 0.10 and 0.15 kg a.i./ha at 20 days of crop sown combined with weedy and weed-free conditions. All the herbicides at each dose effectively controlled the weeds and reduced its dry weight as compared to weedy condition. Alachlor, metolachlor and pendimethalin at 1.5 kg a.i./ha and pendimenthalin at 1.0 kg a.i./ha significantly reduced the population and dry weight of total weeds over the other rates of herbicides. Pendimethalin @ 1.5 kg/ha gave maximum green forage and dry matter yield (448 and 102 q/ha) among herbicide treated plots which were at par with that of weed free condition (466 and 109 q/ha). All the herbicides at higher doses followed the same trend in reduction of dry matter accumulation of weeds and increased in green forage and dry matter yield of maize and cowpea mixed fodder over control. Similarly, with increase in the dose of herbicide the crude protein, nitrogen uptake and DM (dry matter) percent increased significantly.

Abstract

Front line demonstrations (FLDs) were conducted in Faizabad district of Uttar Pradesh to asses performance of short duration rice variety Sushk Samrat on Farmers field in target environment i.e. rainfed upland during Kharif 2011 and 2012. The socio-economic survey of district revealed the real problem associated with rice cultivation. Farmers of the study areas were resource poor and they are still growing local land races in rainfed upland ecosystem. In view of the above mentioned facts frontline demonstrations on newly developed short duration rice variety 'Sushk Samrat' was conducted to improve rice productivity and bridging gap between potential yield and farmers yield of rice. Result of two consecutive years of the FLD's revealed that rice variety Sushk Samrat posses drought resistant coupled with high yielding capacity and it out yielded farmers variety in all the demonstrations. The average of two seasons data revealed that 34.77 per cent higher grain yield of rice (28.87 q/ha) is recorded in demonstrations as compared to farmers' practice (21.42 q/ha). The high positive value (9.76 %) of technology index indicated that technology is highly viable for rice cultivation in rainfed upland ecosystem of Faizabad district of Uttar Pradesh.

Abstract

A field experiment was conducted at Instructional Farm of KVK, Crop Research Station, Masodha of NDUA and T, Faizabad to assess the performance of new wheat varieties under timely sown condition in changing climatic condition. The experiment was laid out in Split Plot Design replicated three times. The treatment comprised of 2 dates of sowing i.e., 15^th November and 25^th November in main plots and four wheat varieties HD 2967, DBW 39, HD 2733 and PBW502 in sub plots. The soil of experimental plot was sandy clay loam in texture having low nitrogen (211.6 kg /ha) and phosphorus (11.49 kg/ha) and medium in potassium (244.6 kg/ha) with soil pH 7.5. The early sowing of wheat (15^th November) produced significantly higher grains yield (54.61 q/ha) than delayed sowing (51.38 q/ha). Earliness in 10 days of sowing of wheat crop in such climatic change conditions influences wheat yield upto 6.29 per cent. The higher yield was due to higher growth and yield attributes influences the growth and development of crops. Among the varieties significantly higher grain yield (53.20 q/ha), straw yield (61.71 q/ha) net return (Rs. 22556.00) and benefit cost ratio (1.86) were obtained with wheat variety DBW 39 over the rest of the three varieties i.e., HD 2967, HD 2733 and PBW 502.

Abstract

Grain quality characteristics (Physico-chemical) of forty five short grain aromatic rices were evaluated in the Biochemistry Laboratory, Crop Research Station, (NDUAT) Masodha, Faizabad in 2012. Physico-chemical analysis of collected genotypes revealed that all these rices possess good grain and cooking quality. Among physical parameters of grain quality, the milling per cent among tested genotypes varied from 50.90 to 70.0 per cent. The maximum milling recovery (%) was recorded for Zeeringa shabha collected from Amethi area of district Sultanpur while volume expansion ratio varied from 1.90 to 5.50. Amylose content (%) ranged from 19.25 to 24.10 per cent. The lowest AC (%) was recorded in 'Lalmati (Kurauli, Barabanki)', whereas highest in 'Kalanamak (Tulsipur)'. Intermediate amylase content was recorded for all the tested rice genotypes.

Abstract

Cryopreservation of gametes and germ cells is an essential tool for germplasm conservation and improvement of productivity in aquaculture. Here, transplantation worthiness of isolated cryopreserved germ cells (GCs) of Indian major carp, rohu Labeo rohita has been tested by their viability and colonization ability in the allogenic host (Catla catla). GCs were cryopreserved using dimethyl sulphoxide (DMSO), ethylene glycol (EG) and glycerol. Rohu GCs were successfully cryopreserved with significantly higher viability using slow cooling rate of -1C/min and a medium containing 1.4 M DMSO compared to EG and glycerol. It was found that more than 70% GCs were viable following this method. Transplantation experiment revealed that frozen/thawed GCs colonized and proliferated in the gonad of the recipients. Hence, this technique of transplantation of GC into adult gonads paves the way for further applications in surrogate animal development.

Abstract

Agroforestry has been defined as a dynamic ecologically based natural resources management system that through the integration of trees on farms and in the agricultural landscape diversifies and sustains production for increased social, economic and environmental benefits for land users at all levels. This paper highlighted agroforestry practices and concepts in sustainable land use systems. The benefit derivable from the interface between forest trees and agricultural crops are enormous. They include the optimal use of land for both agricultural and forestry production on a sustainable basis including the improvement of the quality of soil. This is in addition to the socio-economic benefits that are accruable from agroforestry. Indeed the advantage of agroforestry is all encompassing and germane to a sustainable production system and livelihood.

Abstract

Seed protectants have an important role in enhancing the storability of the legume seed by protecting the legume seeds for long time against pulse beetle, Callosobruchus chinensis during storage. But some seed protectants fail to protect seed due to short residual effect . Due to short persistency on seed , the bruchids can survive and breed easily and maintain their population on stored even treated legumes, later on seed damage badly. Considering this point in view the residual toxicity of eight seed protectants (insecticides) were assessed in stored seed of pigeonpea at different storage periods under ambient condition N.D. University of Agriculture and Technology, Kumarganj, Faizabad. Novaluron 10 EC@ 0.05ml/kg seed had longer persistency on stored pigeonpea seed with maximum toxicity against bruchids upto nine month of storage followed by emamectin benzoate (Proclaim 5SG) @2ppm (40.0 mg/kg seed), indoxacarb (Avaunt 14.5 SC) @2ppm (13.8 mg/kg seed), profenofos (Curacron 50 EC) @2ppm (0.004ml/kg seed) and spinosad (Tracer 45 SC) @2ppm (4.4 mg /kg seed).
