Heterosis For Fodder Yield and its Contributing Traits in Dual Purpose Sorghum (Sorghum Bicolor (L.) Moench) Hybrids
An experiment was conducted to assess the extent of heterosis for fodder yield and its contributing traits in sorghum (Sorghum bicolor (L.) Moench) crosses using line x tester mating design. Thirty hybrids derived from mating five testers with six lines in L x T design along with their parents and two checks viz., CSH 15 R and CSV 22 R were evaluated at Sorghum Research Station, VNMKV., Parbhani (Maharashtra), India. Observations were recorded on randomly selected 5 five plants in each replication for grain yield and its contributing characters. Amongst 30 hybrids evaluated, three hybrids viz., Phule Anuradha x PBMR 3, Phule Anuradha x PBMR 1 and ICSR 196 x PBMR 3 recorded lowest negative heterosis percentage for days to 50% flowering over standard hybrid check (CHS 15 R), varietal check (CSV 22 R) and better parent. In addition the crosses; Parbhani Moti x PBMR 5, PMS 71B x PBMR 5, CSV 29R x PBMR 3, MS 104B x PBMR 3, ICSR 196 x PBMR 3 and Phule Anuradha x PBMR 3 possessed significantly desirable heterosis and per se performance for fodder yield per plant. Parbhani Moti x PBMR 5, PMS 71B x PBMR 5 and ICSR 196 x PBMR 3 have also shown good perse performance and heterosis for fodder contributing traits plant height, no. of leaves, leaf area, biomass and stem girth. Hence this cross is found tobe promising for fodder quality and palatability traits. While hybrids CSV 29 R x PBMR 3, Parbhani Moti X PBMR 4, Phule Anuradha x PBMR 4, Parbhani Moti x PBMR 1 and MS 104B x PBMR 3 expressed significant superiority for heterobeltiosis and standard heterosis for grain yield. Cross CSV 29 R x PBMR 3 and Parbhani Moti x Pbmr 5 are promising for developing dual purpose genotypes.
CONTROL DESIGN OF THE CONVERTER FOR A GRID-CONNECTED PV SYSTEM
Classic and intelligent techniques aim to locate and track the maximum power point of photovoltaic (PV) systems. However, the nonlinear nature of PV arrays regarding ambient conditions and unstable climatic factors hinders the extraction of the maximum power provided by the PV modules. As a result, the PV modules can extract a false MPP and convert less solar energy into electrical energy. Moreover, the choice of the DC-DC converter is essential because it needs to track the MPP regardless of the ambient conditions. This paper presents a solution to design a control scheme for a grid-connected photovoltaic (PV) system to solve the maximum power point tracking (MPPT) problem. The designed control structure solves the nonlinear problems in the model of the inverters.
MUTATIONAL BREEDING IN ORNAMENTAL FLOWERS AND FOLIAGES
Clinical hobby in mutation breeding has extensively decreased for the duration of the final 15 years. Interest in research has shifted in the direction of improvement and application of molecular techniques as gear in breeding and transformation of vegetation. Such strategies permit a more directed technique in pursuance of the breeding goal. Molecular strategies, however, generate high developmental costs and requirestate-of-the-art equipment and a pretty trained body of workers. The investment in such steeply priced. Techniques does no longer appear good enough in case of many decorative species with their restricted financial significance as compared to agricultural vegetation and their every now and then very quick advertising durations in result of permanent demand for brand new elegant products. Further, genetically modified decorative flora are not advertised in Europe at the time being because of low popularity of clients and the unsure prison scenario. Alternatively, decorative flora appear like best systems for mutation breeding as many characters of economic hobby, i.e. Flower traits or the boom addiction are without difficulty monitored after mutagenic treatment. Moreover, many ornamental species are heterozygous and regularly propagated vegetatively. Therefore permitting the detection, choice and conservation of mutants within the M1-technology. Suitable techniques in mutation induction as utility of fractionated doses and recurrent irradiation combined with in vitro lifestyle strategies may additionally lead to fast achievement additionally in homozygous, polyploid species. Even with its accidental character, mutation induction is still an appealing technique for developing genetic variability in ornamentals each time the preferred characters can be predicted in the genetic scope of a given species. Realistic mutation breeding nowadays has end up a habitual approach in many vegetatively propagated ornamental vegetation and is being used by business breeding organizations.
Effectiveness of different packages against some stored product insects
The current study evaluated the effect of packing materials on tested insects. All packages resist the penetration of T. castaneum adults for 15 days post treatment (release of insects). The examination of the all packing materials illustrates that T. castaneum adults failed to penetrate inside the package and there are no any holes except sack cloth package where twenty T. castaneum adults enabled to enter inside after five weeks. T. castaneum could not penetrate any of the packages. Also there were no holes in any of the packages. The average number of the rusty flour beetle inside all types of tested packages indicated that there was no development of it, as its number ranged between 1 to 7.33 compared to the average number inside. The findings indicated to the effectiveness of the all packages used compared to sackcloth bag. Additionally results showed that both adults and larvae of T. castaneum failed to puncture any of the used packages. There is no any holes or insect adults inside the all packages, but the all S. oryzae adults succeeded to enter into sack cloth package. The all packages under study showed high effectiveness against T. castaneum and its larvae, followed by S. oryzae and R. dominica.
Perceived impact of climate change on paddy farming in Nagapattinam district of Tamil Nadu
This study examined the perceived impact of climate change among Paddy farmers in Nagapattinam district of Tamil Nadu state in India. Among the 38 districts of Tamil Nadu, Nagapattinam district was selected to conduct the present study. This is situated in coastal area and very often subjected to natural calamities which were mainly reflected on the paddy cultivation to the worst status. Data for the study were collected from 200 respondents in the study area by adopting simple random sampling technique. The study revealed that the economic fluctuations was highly perceived (0.92) by the respondents when compare to all other impacts of climate change. In addition, the climate change impact on crop nature (0.702), soil (0.689), water (0.706), agro climate status (0.755) were also perceived by the respondents. Decreased crop yield (2.915) and decreased annual income from paddy crop (2.870) were secured high mean score under the criteria of economic fluctuations. Climate change is perceived as a serious threat to paddy eco systems. Changing rainfall pattern might lead to the reduction of water in streams, rivers, water bodies and likely to result in high deposition of salt concentration in the water bodies. As per perceived impact index analysis, crop destruction and decreased annual income from paddy crop were experienced by majority of the respondents due to climate change. Hence, identification and popularization of alternative cropping system in the study area would help the affected farmers to cope with adverse climatic condition. Further, in order to improve the organic carbon content of the soil the importance of organic manures, vermiculture, biofertilizers, biopesticides has to be popularized for conserving soil fertility.
