N Management

Efficient N management practices usually involve many potential strategies, but always involve choosing the correct amount of N and the coupling of N management to efficient water management. Nitrogen management strategies are integral parts of improved production practices recommended by land-grant universities such as the Institute of Food and Agricultural Sciences, Univ. of Florida. This paper, which draws heavily on research and experience in Florida, outlines the concepts and technologies for managing vegetable N fertilization to minimize negative impacts on the environment.

Abstract Aim To study the demographics, clinical profile, management strategies, and treatment outcomes of intracranial epidermoid lesions. Materials and Methods A single institutional retrospective analysis from a large institute in Western India was done of all patients operated for intracranial epidermoid tumors over a period of 20 years from January 1997 to January 2017. All patients were investigated with a contrast-enhanced computed tomography (CECT) as well as a magnetic resonance imaging (MRI), with a diffusion-weighted imaging to confirm diagnosis of epidermoid tumor. The presenting complaints and the demographics of all patients were recorded, and all patients underwent planned surgery, with or without a cerebrospinal fluid (CSF) diversion procedure as per requirement. Surgery ranged from a gross total resection to a near-total resection depending on the patient, location of the lesion, and involvement of adjacent structures. All patients underwent an immediate postoperative computed tomographic (CT) scan as well as a follow-up MRI. Patients were followed up to note clinical improvement as well as documentation of all complications. Results Total 234 patients of intracranial epidermoid tumors were operated upon in a 20-year span. Males predominated with a total number of 146 (62.4%). The most common age group was the fourth decade. The most common presentations were headache (118 patients) and neuralgia in the trigeminal distribution (82 patients). Infratentorial compartment was the most common location of the tumors (152 patients), with cerebellopontine angle being the predominant site in the posterior fossa (107 patients). Both supra- and infratentorial compartments were involved in 28 cases. Gross total excision could be achieved in 202 patients. Reoperation was required in 12 cases. The mean follow-up period was 68 months. The most common complication encountered was that of postoperative CSF leak (24 patients). We had eight cases of recurrence and six deaths in our series. Conclusion Epidermoid tumors can arise in virtually all intracranial locations. Gross total excision of the tumor is treatment of choice and can be curative for these benign lesions. Large lesions at presentation with involvement of multiple compartments can be difficult to manage and may require bicompartmental or second look surgery. Complete excision of the capsule with preservation of adjacent neuronal and vascular structures is of utmost importance to decrease postoperative morbidity and chances of recurrence. Perioperative steroids, avoidance of intraoperative spillage, and intraoperative endoscopic assistance are recommended in all cases.

The field experiment was conducted during kharif 2014 and 2015 at ZARS, V. C. Farm, Mandya to study the effect of precision nitrogen management on growth, yield and economics of drip irrigated maize. There were 9 treatments replicated thrice in Randomized Complete Block Design. Among the various treatments, drip fertigation of nitrogen through Soil Plant Analysis Development (SPAD) meter sufficiency index of 95-100 per cent under paired row (30/90) recorded significantly higher growth and yield parameters viz., plant height, LAI, total dry matter production, cob length, number of rows per cob, number of kernels per cob and cob weight along with kernel (85.73 and 86.78 q/ha) and stover yield (140.4 and 145.3 q/ha) during both the years of experimentation as compared to UAS Bangalore package with surface irrigation and normal spacing of 60 cm X 30 cm and was being on par with nitrogen management through Leaf Colour Chart (LCC) 6, SPAD sufficiency index of 90-95 per cent and LCC 5. The SPAD sufficiency index of 95-100 per cent registered higher net returns (Rs. 69,634 and Rs. 77,614, respectively) and B:C ratio (2.82 and 3.00, respectively) followed by LCC 6.

Research indicates that there is considerable potential for a successful switch from high chemical use to lower-input, more sustainable farming practices for maize. The overall objective of the MicroMaize project was to field-test the performance of innovative microbiological management strategies. The effect of microbial consortia on maize growth and grain yield was studied in 2008 and 2009 at Martonvásár (Hungary) in a 50-year-old long-term fertilisation experiment. The experiment was set up in a split-plot design with four replications. The main plots were the fertilisation treatments: A: control, without fertilisation (N 0 P 0 K 0 ), B: N 50 P 24 K 43 , C: N 100 P 48 K 87 , D: N 200 P 96 K 174 , E: N 300 P 144 K 261 . Three microbial inoculation treatments were the sub-plots: C0: control, no microbial consortia, C1: A. lipoferum CRT1 + P. fluorescens Pf153 + G. intraradices JJ 129 , C2: A. lipoferum CRT1 + P. fluorescens F113 + G. intraradices JJ129 . The results indicated that the microbial consortia had no significant effect on maize growth and yield. In the ecophysiological analyses, the microbial consortia were found to have a significant positive effect on the chlorophyll content and on the protein and nitrogen contents of the grain yield in 2009. The long-term results revealed that the mineral fertilisation treatments and the year had a significant influence on the growth, yield and grain quality parameters of maize. The effect of nutrient supplies and year during the vegetative growth phase of maize could be quantified using the mean values of the absolute growth rate (AGR) for maize shoots and roots and with the nutrient stress index calculated from AGR. Further field investigations on productivity and eco-physiological parameters will be needed to estimate the effect of microbial consortia.
