Mustard is cultivated throughout the world for oil in its seeds. Itrequires high nitrogen input for improved productivity but the nitrogen appliedto the soil is not fully utilised by the crops due to various constraints. Theobjective of the reported research was to determine if foliar- appliedgibberellic acid (GA3) could enhance crop growth and(More)
We tested the mode of action of Cd on photosynthesis and activities of ATP-sulfurylase (ATP-S), catalase (CAT), superoxide dismutase (SOD), ascorbate peroxidase (APX), glutathione reductase (GR), and on contents of phytochelatins (PCs) and glutathione (GSH) in two cultivars of wheat (Triticum aestivum L.) PBW-343 and WH-542 differing in yield potential. Cd(More)
The ground water (GW), treated wastewater (TW) and the soil at the agricultural farm in the premises of the Mathura Oil Refinery have been monitored for various physico-chemical characteristics, over the last 12 years (1987-1998). It was noted that the heavy metal content in the soil, repeatedly irrigated with TW, was increasing because the wastewater(More)
Earlier research has shown that exogenous gibberellic acid (GA3) application increases shoot growth, photosynthesis and soil nitrogen (N) utilisation in mustard (Brassica juncea L. Czern & Coss.). Mustard has a high sulfur (S) requirement. Its assimilatory pathway is well coordinated with N and dependent on photosynthesis. Thus, the higher photosynthate(More)
The vast majority of eggs in Australia are washed prior to packing to remove dirt and fecal material and to reduce the microbial contamination of the egg shell. The egg contents can be an ideal growth medium for microorganisms which can result in human illness if eggs are stored improperly and eaten raw or undercooked, and it is estimated that egg-related(More)
The crop of sugarcane (Saccharum officinarum) was grown at the agricultural farm of the Mathura Oil Refinery in a simple randomized block design. The experimental plots were irrigated with ground water (GW) or treated wastewater (TW) as and when required The plants gave better response to the latter than the former. The quantity of the required nutrients(More)
Foliar sprays of water or 1, 10 and 100 µM aqueous solutions of gibberellic acid (GA3) or kinetin (KIN) were applied to 40-d-old plants of Nigella sativa (L.) to study their effects on net photosynthetic rate, nitrogen metabolism, and the seed yield. 10 µM solutions of both the hormones, especially GA3, appreciably increased the activities of nitrate(More)
Pyridoxine, applied to seeds before sowing or by the spraying of a standing crop of moong (Vigna radiata) significantly enhanced leaf nitrate reductase activity (NRA). Leaf NRA levels, being significantly correlated with seed yield, can be utilized for predicting crop productivity and for adopting corrective measures, if necessary, at an early growth stage.
The crude lysosomal fraction of corn seedling root tips contains an arylsulphatase (E.C. 3.1.6.1) which hydrolysed p-nitrophenyl sulphate at pH 8.0 but had no activity towards p-nitrocatechol sulphate. The Km value for p-nitrophenyl sulphate was 1.24 mM. The hydrolysis of p-nitrophenyl sulphate was linear up to 2 h and the rate was proportional to the(More)
Soaking the seeds of mungbean (Vigna radiata L. Wilczek cv. K-851) in pyridoxine solution significantly enhanced leaf N, P and K concentrations at different growth stages, and seed protein concentration at harvest. Leaf N, P and K were significantly correlated with root length and seed protein. Thus, pyridoxine application not only enhanced the availability(More)
