A three year field experiment was conducted during September - March of 2010-2011 to 2012- 2013 at Agricultural College and Research Institute, Killikulam to study the influence of humic acid with graded levels of inorganic fertilizers on productivity, nutrient uptake, economic and soil fertility of brinjal var KKM1. The experiment was carried out in Randomized Block Design replicated thrice with 11 treatments. Humic acid was applied through both in soil and foliar spray with 75 per cent RDF (N75 P37.5 K22.5). Application of 75 per cent RDF (N75 P37.5 K22.5) + 10 kg HA (SA) + 0.2 per cent HA (FS) /ha produced significantly higher plant hight (112.0 cm), days to 50 per cent flowering (56.4), number of branches/plant (9.4), number of fruits /plant (25.3), single fruit weight ( 69.9 g), fruit yield (33.4 t/ha), total dry matter production (10.08 t/ ha), net return (Rs. 1,33,131 / ha) and B:C ratio (4.29), N, P and K (143.1, 33.3 and 148.6 kg/ha, respectively) uptake compared to control. However, 75 per cent RDF (N75 P37.5 K22.5) + 10 kg HA (SA) + 0.1 per cent HA (FS) /ha had higher plant height, number of branches, days to 50 per cent flowering, number of fruits per plant, single fruit weight, fruit yield, total dry matter production, net return, B:C ratio, N,P and K uptake. Significant built up of organic carbon (0.92 %), available N (291.5 kg/ha), available P (25.4 kg / ha) and available K (293.7 kg / ha) was registered with 75 per cent RDF + 10 kg HA (SA) + 0.2 per cent HA (FS) /ha. The maximum balance of N, P and K (25.5, 8.6 and 25.2 kg/ha, respectively) were recorded under the treatment with application of 75 per cent RDF + 10 kg HA (SA) + 0.2 per cent HA (FS) /ha.Keywords

Knowledge of spatial variability in soil fertility is important for site specific nutrient management. In the current study, the spatial variations of soil pH, organic carbon, N, P, K, Fe, Cu, Mn and Zn were evaluated in Orathur village (Typic Haplusterts) of Veeranam command area of Cuddalore district, Tamil Nadu. Global positioning system (GPS) guided surface soil sampling (0-15 cm) were done over an area of about 100 hectares in a 100 x 100 m grid. Wide ranges of variation were noted for different soil physico-chemical properties as well as nutrient status in the study area. The pH of soils ranged from 6.70 to 8.30, organic carbon ( %) varied from 0.49 and 0.88, available nitrogen (kg ha-1) from 173.60 to 235.20, available phosphorus (kg ha-1) content varied from4.90 to 17.10, available potassium varied between 180.00 to 330.0 kg ha-1, while available S content varied from 3.10 to 21.30 ppm. The available Fe and Mn varied from 3.26 to 20.16 ppm and 0.94 to 8.26 ppm. The variation of soil nutrient contents across the study area was found to be related to the fertilizer use pattern among farmers. The evaluated physico-chemical and nutrient status data of the area were used to develop variability maps with the aim of generating site -specific nutrient management strategies.Keywords

The study was undertaken to find out the nutrient optima for maximum yield and the nutrient removal by hybrid maize through balanced fertilization by a systematic approach on soil fertility evaluation. In nutrient sorption study, the nutrients viz., phosphorus (P), potassium (K) and zinc (Zn) were found as limiting nutrients in these soils and these were considered as deficient nutrients. The optimum nutrient levels of NPK and Zn were fixed by sorption studies as 200: 64: 48 and 4.8 kg ha-1 for this soil series. Nitrogen level was fixed for optimum nutrient treatment at 200 kg ha-1 for this experimental soil series (N2P2K2Zn) with a zero level and one below and one above this level of N were arrived. The field experiment was conducted at farmers’ field with maize (COHM 5) as a test crop. The highest grain yield (8005 kg ha-1) was recorded in the treatment with 250:64:48:4.8 kg of NPK and Zn ha-1. The highest total N uptake (260.80 kg ha-1) of maize in Mayamankuruchi series was noticed in the treatment with 250:64:48:4.8 kg of NPK and Zn ha-1. The application of 200:80:48:4.8 kg of NPK and Zn ha-1 resulted in the highest total P uptake (74.80 kg ha-1). The highest total K uptake (216.24 kg ha-1) was observed for the treatment of 200:64:60:4.8 kg of NPK and Zn ha-1. The application of 250:64:48:4.8 kg of NPK and Zn ha-1 resulted in the highest total Zn uptake (1.597 kg ha-1).Keywords
