A field experiment was conducted in the central farm, Regional Research and Technology Transfer Station, Coastal Zone OUAT, Bhubaneswar, Odisha, India during kharif 2020 using cv-Lalat variety of Rice. The experiment was laid out in randomized block design (RBD) with ten treatments and three replications. In this experiment BOF (Basic Oxygen Furnace) slag was used as a source of silica for application to rice crop. 200, 300 and 400 kg SiO2/ha was applied in combination with 50% STD (Soil Test Dose) and 75% STD to assess the efficacy of Silica with reduction in fertilizer dose by 50% and 25%. It was shown that increase in number of effective tillers (7.8) per plant and length of the panicle (25.8 cm), but no significant increase was marked in case of 1000 grain weight (gm.) over control. In case of grain yield, straw yield and harvest index, 100% STD (T4) registered maximum (36.9q/ha) grain yield which was 29.4% more than that of control. Of course, grain yield in case of T9 i.e., 75% STD+300 kg SiO2/ha was at par 36.2q/ha indicated efficacy of silica application by reducing fertilizer dose. Harvest index was not affected by Si treatments. However, maximum HI (0.478) was observed in T9. Available N, P, K and S status in post-harvest soil was increased due to application of silica along with fertilizer over control indicated better availability of nutrients which plays a vital role in increasing production and productivity of rice. The study revealed that the DTPA extractable Fe and Mn content decreased, and Cu and Zn content increased with increased application of silica. Though 100% STD (T4) was found to be very effective as compared to other treatments but 75% STD + 300kgSiO2/ha was also equally effective so far as yield, growth attributing characters, available nutrient status of paddy.

An experiment was conducted at the Agronomy Field Laboratory, Bangladesh Agricultural University, Mymensingh from July to December 2004 to evaluate the effect of hill spacing on the performance of BRRI dhan40 and BRRI dhan41 as Transplant aman crop. The experiment consisted of five hill spacings viz., 5cm. 10cm, 15 cm, and 25 cm where row to row spacing of 25 cm was kept constant for all treatments. The experiment was laid out in randomized complete block design with four replications. The 25 cm x 5 cm hill spacing produced the tallest plant, highest total number of tillers/hill, bearing tillers/hill lowest number of non-hearing tillers/hill, grain yield and harvest index, while 25 cm x 5 cm hill spacing produced the highest number of sterile spikelets/panicle, straw yield and biological yield. BRRI dhan41 produced higher grain yield (4.7 t/ha) which was the contribution of higher number of grains/panicle and heavier grain weight. Lower yield (4.51 t/ha) was recorded in BRRI dhan40.Key Words: Varietal performance; T. aman rice; hill density.DOI: 10.3329/bjar.v34i1.5750Bangladesh J. Agril. Res. 34(1) : 33-39, March 2009

The experiment was conducted to classify the maximum glutenin protein possessed Pakistani bread wheat genotype for superlative chapati making quality by ten yield-related parameters. The studied germplasm was acquired from NARC, Pakistan, and planted in randomized-complete-block-design with four replicates at the screen house of the Genetics Department. Data were assessed via Duncan’s test, correlation analysis, SDS-PAGE, and cluster analysis. Duncan’s test conceded that Pirsabak-85 had the highest plant height, flag leaf area, biomass, grain yield plantˉ1, harvest index, and protein content. While, the correlation studies showed that plant height, tillers plantˉ1 (r = 0.649), fertile tillers plantˉ1 (r = 0.713),biomass (r = 0.861), spike length (LS), thousand-grain weight and harvest index had a positive higher significant association with grain yield plantˉ1. The SDS-PAGE analysis resolved 30 diverse high and low molecular weight bands, ranging from 200 kDa to 28 kDa glutenin subunits. Among genotypes, Pirsabak-85 showed maximum protein content and 10 Glu-1 scores. The dendrogram analysis revealed that Pirsabak-85 associated with cluster-II, which was a major and most diverged cluster. The Pirsabak-85 can be utilized to enhance bread wheat production and better chapati making quality

The effect of introgression of the temperate maize population BUGARD on the grain yield of a low-yielding tropical maize population well appreciated for the quality of its grains, NCP80, was studied. NCP80 was crossed with BUGARD to obtain the F1. The BC1 obtained by backcrossing the F1 to NCP80 was random mated thrice. The tropical parent NCP80 and the BC1 (NBN) were evaluated in two tropical locations using a randomized complete block design with three replications. Introgression of the temperate population BUGARD into the tropical population NCP80 significantly increased grain yield. The resulting population, NBN, appeared, moreover, significantly earlier than NCP80 and not significantly different from it for resistance to rust, tropical blight and maize streak, ear height, husk cover and harvest index. NBN may, further, be improved for resistance to maize streak and grain yield by recurrent selection.

A field experiment on the standardization of organic module for production of fenugreek (Trigonella foenum graecum L.) was conducted during rabi season of 2009-10 to 2012-13 (four years). The experiment was laid out in Factorial Randomized Block Design (RBD) consisting of three organic modules (M1, M2 and M3) and two fenugreek varieties (AFg-1 and RMt-305) with four replications. Findings of present study showed significant differences among the performance of different organic modules tested for two fenugreek varieties. Organic module-1 (M1)comprising of soil application of vermi-compost @5 t/ha+ foliar spray of 5% garlic extract @ 2.0 kg/ha + 2% neem oil @ 5 litre/ha+ soil application of neem cake @150 kg/ha and Trichoderma @ 2.5 kg/ha, seed treatment with Rhizobium @100 ml/kg seed, PSB @ 100 ml/kg seed and Trichoderma @10 g/kg seed exhibited earliest seed germination and maximum plant height (5.78, 19.69, 43.39 and 50.97 cm) at 30, 60, 90 DAS and at harvest, respectively with maximum number of branches (6.76/ plant), number of pods (42/ plant), number of seeds (16.01/ pod), highest grain yield (1515.21 kg/ha), gross return (100004) and net returns (66741) in fenugreek crop. Similarly significant differences were recorded in the performance of fenugreek varieties under different organic modules and the highest plant height, maximum number of branches and pods per plant, highest number of seeds per pod with maximum grain yield (1568.36 kg/ha), gross returns (103512), net returns (71399) with higher B:C ratio (2.22) were recorded in fenugreek variety AFg-1 than variety RMt-305. Cultivation of fenugreek variety AFg-1 with the application of Module-1 exhibited maximum values for all the growth parameters, yield attributing characters, maximum grain yield, net returns with improvement in soil organic carbon % (OC) and soil fertility (available N, P and K) after 4 crop cycles. Hence, variety AFg-1 is recommended to grow organically with the application of Module-1 (M1) under semi-arid environmental conditions

The objective of this study was to evaluate the behavior of forage sorghum when intercropped with piatã grass and cultivated in eucalyptus sub-forest. The experiment was carried out at the Embrapa Gado de Corte, in Campo Grande - MS. The experimental design was a randomized complete block design with three replications. The main treatments were: monoculture (single sorghum); intercropping (simultaneous sowing of sorghum + piatã grass). The secondary treatments were composed by the sampling sites, with five sites equidistant between the rows of eucalyptus trees (CLFI), with full sun as a control (CLI). The percentage of shading was always higher than 30% in the sub-forest, and the overall average of the system with 63% shade, even after 50% thinning of eucalyptus trees. The intercropping with the grass, an interesting fact, did not affect sorghum grain yield, since it validates the potential of forage sorghum for use in intercropping with perennial grasses, with average grain yield of 2,404.63 kg ha-1. Regarding the sampling sites, it was observed a higher yield in the full sun with 3,283 kg ha-1. The weight of 100 grains was higher for sorghum in monoculture. On the other hand, the upper W1000 was observed at sites A and C. The weight of 1000 grains is considered stable, being affected only under conditions of stress during grain formation. The sorghum intercropped with the piatã grass did not influence the harvest index (HI), while in the shaded environment there was an increase in the harvest index in relation to the full sun.
