Field experiments were conducted at Tamil Nadu Agricultural University, Coimbatore, Tamil Nadu, India during the Rabi (November 1997-March 1998) and Kharif (July 1998-November 1998) seasons to identify the effect of silicon at panicle initiation on the growth of rice plant (Variety ADT-36) at different growth stages. Furnace slag was applied as a silicon source at 2 t/ha at the panicle initiation stage along with other nutrients. The dry matter production was recorded at the active tillering, panicle initiation, booting, flowering, one week after flowering and maturity stages in both the seasons. The total dry matter production was greater in the Kharif season than in the Rabi season. The application of slag at the panicle initiation stage along with N and K at the flowering stage had a significant influence over the dry matter production. A similar trend was observed in both the seasons. The silicon uptake was recorded at the panicle initiation and maturity stages. About 30-40% of the silicon absorbed during the early stages and the maturity stage was present in the shoot, whereas 20-30 % of the silicon absorbed during the maturity stages was present in the leaf blades. Based on the results, it is concluded that the supply of silicon during the panicle initiation stage is most important for plant growth.

Two experiments were established 1 May through 1 December 1991 and 1992 to determine the monthly nutrient uptake and dry matter production of the 'Gunung' yam (Dioscorea alata) grown on an Ultisol. During the first year the plants were fertilized with 0; 667; 1,333; 2,000 and 2,667 kg/ha of a 15-5- 15-5 (N, P2O5, K2O and MgO) fertilizer supplemented with a minor element mixture. No fertilizer was applied the second year. Biomass harvests were conducted at 2, 3, 4, 5, 6 and 7 months after planting. At each harvest, the plants were dug-up and separated into leaf-laminas, vine and petioles, roots and tubers. Fresh and oven-dry weights of the plant components were determined and samples from each were analyzed for N, P, K, Ca and Mg. Regardless of the year, tuber dry matter yield was not significantly affected by the fertilizer treatment. Maximum nutrient uptakes were 214 kg/ha of N, 19 kg/ha of P, 223 kg/ha of K, 95 kg/ha of Ca and 9 kg/ha of Mg. Nitrogen, K and Ca uptake peaks occurred about five months after planting. Maximum dry matter production was 11,303 kg/ha, 8,672 kg/ha of which was tuber dry weight. The dry matter production peak occurred at the completion of the 7-month cropping cycle. The plants utilized 24.7 kg/ha of N, 2.2 kg/ha of P, 25.7 kg/ha of K, 11.0 kg/ha of Ca and 1.0 kg/ha of Mg, for every 1,000 kg/ha of edible dry matter produced.

Background: Growth and yield characteristics of genotypes depend on genetic and environmental factors. Among the different production factors, varietal selection at any location plays an important role. Proper crop management depends on the growth characteristics of various varieties to get maximum benefit from new genetic material. Among the different water- saving irrigation methods in rice, the most widely adopted is alternate wetting and drying (AWD). Many of the rice cultivars vary in their performance under different systems of cultivation.Methods: A field experiment was conducted on a clay loam soil at Indian Institute of Rice Research (IIRR) Rajendranagar, Hyderabad, Telangana during the kharif seasons of 2017 and 2018. to study the “productivity and water use efficiency of rice cultivars under different irrigation regimes and systems of cultivation” The treatments consisted of two irrigation regimes Alternate wetting and drying and Saturation as main plot treatments, three establishment methods System of Rice Intensification (SRI), Drum Seeding (DS) and Normal transplanting (NTP) as sub plot treatments and four Cultivars namely DRR Dhan 42, DRR Dhan 43, MTU-1010 and NLR-34449 as sub-sub plot treatments summing up to 24 treatment combinations laid out in split-split plot design with three replications.Result: At 60, 90 DAS/DAT and harvest significantly dry matter production (DMP) was recorded with DRR Dhan 43 cultivar (607, 4320 and 11548 kg ha-1 respectively in pooled means of both 2017 and 2018) than other cultivars. Whereas MTU-1010 and NLR-34449 recorded on par dry matter production values at all the crop growth stages during both the years of study. However, DRR Dhan 42 produced the lowest dry matter production compared to other genotypes. DRR Dhan 43 recorded higher dry matter accumulation (g m-2) in root, stem and leaves at all the crop growth stages, during both the years of the study over other cultivars. Alternative wetting and drying method of irrigation recorded significantly higher DMP at all the growth stages of rice (60, 90 DAS/DAT and at harvest) except at 30 DAS/DAT during both 2017 and 2018 as compared to saturation. SRI recorded significantly higher DMP as compared to normal transplanting; however, it was comparably at par with drum seeding at all the growth stages.

The aim of this study was to investigate the effects of different doses of biochar (BC) and cadmium (Cd) on the yield and nutrient uptake of maize plant. It was carried out in 3 replications of 3 kg pots under greenhouse conditions. In the study, biochar (0% and 2% w/w) which is attained from rosehip seed and 4 different Cd doses (0 mg/kg, 2 mg/kg, 4 mg/kg and 8 mg/kg) were applied. In the research, P2088 maize species was used and harvested approximately 60 days after sowing and shoot dry matter production, Cd, nitrogen (N), phosphorus (P), potassium (K), calcium (Ca), magnesium (Mg), iron (Fe), zinc (Zn), manganese (Mn) and copper (Cu) concentrations were determined of maize plant. According to the results, the highest dry matter production was obtained with 27.52 g/pot in 2% BC and 4 mg/kg Cd application. However, in the research, dry matter production decreased with increasing Cd application in 0% BC application, whereas all Cd applications increased dry matter production in 2% BC application compared to control. The highest concentrations of P and K (0.39% P and 2.54% K) were determined in 0% BC and 2 mg/kg Cd, 2% BC and 0 mg/kg Cd applications whereas the highest N concentration of maize plant was determined in 2% BC and 0 mg / kg Cd application with 2.23% N.

A field experiment was conducted during Kuruvai season at the Experimental Farm, Department of Agronomy, Annamalai University to evaluate the performance of early post emergence application of herbicides on weed control in transplanted rice. The experiment was carried out in a Randomized Block Design with eight treatments and three replications. All the imposed treatments significantly influenced the weed parameters and crop parameters in rice. The experimental results revealed that, hand weeding twice at 20 and 40 DAT recorded the lowest total weed count (13.74), highest weed control efficiency (WCE) (92.79 per cent), highest plant height (85.76 cm), higher leaf area index (4.28), higher crop dry matter production (7689 kg ha-1 )and highest nutrient uptake by rice crop (134.79, 33.17, 99.41 kg of N, P2O5 , K2O ha-1, respectively) which was statistically on par with application of penoxsulam + cyhalofop butyl@135 g ha-1 (premix)(15 DAT) that recorded the total weed count (16.74), weed control efficiency (91.21 per cent), plant height (85.03cm), leaf area index (4.19), dry matter production (7567 kg ha-1), crop nutrient uptake (132.37 , 32.48, 97.25 kg of N, P2O5 , K2O ha-1, respectively). Highest total weed count, with lowest plant height, leaf area index, crop dry matter production and crop nutrient uptake were recorded with unweeded control.
