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.

SUMMARYA field experiment was conducted for two consecutive years commencing in 1979–80 on the Indo-Gangetic alluvial soil of Pura to investigate the requirements for zinc of wheat, chickpea, mustard and Egyptian clover. Chickpea and Egyptian clover were more sensitive to zinc deficiency than wheat and mustard, respectively. Average total dry matter production by Egyptian clover and wheat was larger than mustard and chickpea. Egyptian clover and wheat required more zinc to achieve maximum dry matter production but they also recovered from the soil a larger proportion of applied zinc than chickpea and mustard. Mustard produced the most dry matter per unit of zinc absorbed.

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.

Aerobic rice is a new way of cultivating rice that requires less water than lowland rice. A field experiment was conducted during the kharif season of 2015 to evaluate the effects of nutrient management with Biofertilizers on growth and yield attributes, yield, nutrient uptake and economics different rice cultivars. The experiment was laid out split plot design with four replications. Main plot treatments consisted of two cultivars viz., whereas, sub plot treatments comprised of nutrient management practices namely, N1-125% RDF, N2-125% RDF + Biofertilizers, N3 -100% RDF, N4 -100% RDF + Biofertilizers, N5-75% RDF, N6-75% RDF + Biofertilizers. The source of biofertiliser was a combination of Azospirillum, Phosphorus Solubilizing Bacteria and Potassium Solubilizer applied @ 5 kg/ha-1. Crop dry matter production (2582.3 g/m2), root dry matter production (910.1 g/m2), tillers/m2 (566), leaf area index (4.54), panicles/m2 (535), panicle length (23.81), panicle weight (4.56) and test weight (25.3) was higher in PA 6444 compared to DRR Dhan 44. Higher uptake of nutrients was also observed in PA 6444. Rice fertilized with 125% RDF + Biofertilizers (N2) produced higher crop (2901.6 g/m2) and root dry matter production (1028.1 g/m2), tillers/m2 (561) and leaf area index (5.19). This treatment also recorded higher yield attributes and grain yield (3.55 t/ha). With respect to nutrient uptake, application of 125% RDF + Biofertilizers (N2) recorded      higher N, P and K uptake by grain and straw and higher profitability (1.57) than other nutrient combinations.
