Effect of establishment methods and weed management practices on weed control, growth and productivity of blackgram in tarai region of India
A field experiment was carried out in blackgram to find out the effect of various weed management practices and different establishment methods on growth, weed density, weed dry matter, yield and yield attributes at N. E. Bourlag crop research center of G.B.P.U.A&T, Pantnagar during kharif season of 2016. Field experiment was consisted of 2 main plot treatment i.e. raised bed and flat bed and 4 sub-plot treatment i.e. weedy check, Pre emergence (PE) application of pendimethalin 30EC @1.0 Kg/ha, post emergence (PoE) application of imazethapyr 10 SL @ 0.055 kg/ha applied at 20DAS and PE application of pendimethalin 30EC @1.0 Kg/ha + PoE application of imazethapyr 10 SL @ 0.055 kg/ha applied at 20DAS applied as which was carried out under a split plot design. Growth parameters, yield, yield attributes, weed density and weed dry matter was not affected significantly by different establishment methods except number of pods per plant, although raised bed method produced better result than flatbed method. Significantly, higher yield attributes and grain yield per hectare was obtained due to different weed management practices. Pendimethalin @1.0kg/ha 30 EC as PE, imazethapyr @0.055 kg/ha 10SL at 20 DAS as PoE, PE application of pendimethalin 30EC @1.0 Kg/ha + PoE application of imazethapyr 10 SL @ 0.055 kg/ha applied at 20DAS produced significantly higher productivity by 133.7 and 100.4 and 221% over weedy check respectively. Lowest weed density and weed dry matter was recorded under PE application of pendimethalin 30EC @1.0 Kg/ha + PoE application of imazethapyr 10 SL @ 0.055 kg/ha applied at 20DAS.
Assessment of leveraging impacts of micronutrients, biofertilizers and growth regulators on biochemical characters of pomegranate cv. Bhagwa
Assessment of leveraging impacts of chelated micronutrients, growth regulator and biofertilizers on biochemical characters of pomegranate (Punica granatum L.) cv. Bhagwa” was carried out on experimental fruit orchard of Department of Horticulture, VNMKV., Parbhani, during Mrig bahar in 2018-19 and 2019-20. This experiment was laid out in Factorial RBD, which is replicated twice with two factors i.e. Factor A: methods of plant propagation (P) i.e. P1: Air layered plants, P2: Tissue cultured plants and Factor B: different nutrients concentrations i.e. N1: Chelated micronutrients (CM.) @ 3.0 g/lit, N2: CM. @ 4.0 g/lit, N3: GA3 @ 75 ppm, N4: GA3 @ 100 ppm, N5: Biomix @ 0.3%, N6: Biomix @ 0.4%, N7: CM. @ 3.0 g/lit and Biomix 0.3%, N8: CM. @ 3.0 g/lit and GA3 75 ppm and Biomix 0.3%, N9: CM. @ 3.0 g/lit and GA3 75 ppm, N10: GA3 75 ppm and Biomix 0.3%, N11: Control. The result revealed that biochemical characters of fruits regarding TSS, total sugars, reducing sugars, ascorbic acid and anthocyanin content increases with application of chelated micron. @ 3.0 g/l + GA3 @ 75 ppm + Biomix @ 0.3% with interaction of tissue cultured plants. Whereas, acidity of fruit is reduced due to combined application of chelated micron. @ 3.0 g/l + GA3 @ 75 ppm + Biomix @ 0.3% with interaction of tissue cultured plants. This foliar application has produced significantly superior effect on biochemical parameters.
Potential of agroforestry and constraints in its adoption by the farmers
Agroforestry (AF) is an interdisciplinary endeavour that integrates agriculture and livestock with forests. It can assist by raising total productivity by utilising a blend of crops and trees. Examining the potential of AF and the obstacles farmers experienced in adopting it was the goal of the current study. A thorough survey was conducted in each of the four Tehsils as part of the study's implementation in the district of Jagatsinghpur, and 120 farmers who were chosen at random were questioned using a standardised questionnaire. According to our findings, 91.6% of farmers practiced AF for financial gain, and the majority of them farmed Areca catechu and Cocos nucifera on their farms. Most farmers expressed interest in replacing Tectona grandis with fast-growing species like Acacia auriculiformis and Mangifera indica in order to generate rapid financial returns. The main obstacles to farmers adopting AF were transportation issues involving wood-based markets and natural disasters, such as CYCLONE. For this reason, farmers are not growing timber species. The government should successfully construct the AF system so that farmers may embrace it on both a social and economic level. Reviving marketing resources as well as monetary and technological incentives is also necessary.
Designing Cross-Coupled Trisection Substrate Integrated Waveguide Filter with Novel Hexagonal Resonator
This article presents an analysis of substrate-integrated waveguide (SIW) hexagonal resonator structure and its applications to bandpass filters are submitted. The filter is composed of The developed third-order hexagonal resonator filter structure side-by-side horizontally oriented SIW cavities, which are coupled in turn by evanescent waveguide sections with three direct couplings and one cross-coupling between the first and third SIW cavities. Since any of the six sides of a hexagonal resonator can be utilized for lovemaking, the filter configurations are flexible and adaptable. By changing the coupling sides of the hexagonal resonators, two types of experimental circuit configuration at the same central frequency of 8.15 GHz but with different fractional bandwidths of 3 and 6%, including third-order Chebyshev and crossed-coupling trisection, are constructed, fabricated, and measured. To validate the proposed structure, third-order bandpass pooled filters, of the Chebyshev type, are designed using the printed circuit. The final results show simulation is almost similar to the ideal results. Filters display a simple, selective structure of frequency.
Determination of the site of the protonation of substituted hydrazobenzenes
The aim of this work is the determination of protonation site of hydrazobenzene derivatives in gas phase by using ab initio calculations. Optimizations of neutrals and N-ptotonated species are effectuated at the DFT/B3LYP method with the 6-311+G(d,p) basis set. Introduction of natural bond orbital NBO population analysis, fukui functions and local softness s( f )k are calculated to determine the most site of hydrogen attack. Energetic comparison between N1 and N2 protonated compounds were effectuated to determine the most stable protonated species. The protonation occurs preferentially on the nitrogen atom of the substituted cycle. Structural analysis of all the neutrals and N-protonated species correspondents is effectuated to analyze the geometry changes between the N-protonated and neutral ones. Different global chemical parameters of reactivity have been calculated to determine a reactive compound.
