Tomato is an important commercial vegetable crop grown throughout the world, is also known to tolerate the calcareous soil conditions. But, phosphorus availability is a major constrain affecting its yield and productivity. Application of sulphur(S) is known to enhance its availability through bio-chemical reactions and desorption process. To ascertain the quantity of P and S required to enhance the productivity of tomato, a field experiment was conducted in calcareous clay loam soil with five levels of P2O5 (312.5, 250, 187.5, 125 and 0 kg ha-1) and four levels of S, applied at the rate of 2.5, 1.5, 0.5 and 0 per cent (w/w) equivalent to active CaCO3 in soil. Increased rate of P and S application enhanced tomato growth recording highest with P312.5+ S2.5 which was on par with P250+S2.5. But, the highest fruit setting rate (69.37%) was obtained with P250+S2.5 resulting in higher number of fruits per cluster (4.94), fruits per plant (41.17), fruit weight (77.60 g), fruit diameter (5.17cm). All these yield parameters were manifested into marketable tomato fruit yield recording maximum of 42.30 t ha-1 with P250+S2.5. The study established that application of 250 kg ha-1 P +2.5% S found to be statistically optimum for tomato in terms of its yield (42.30 ton ha-1).Keywords

An extensive survey was carried out to study the effect of irrigation water on soil sodification, in terms of soil sodium adsorption ratio (SAR) and residual sodium carbonate (RSC), in a typical black soil of Karnataka and it was carried out in Mudhol taluka of Bagalkot district. The soil SAR and RSC varied greatly up on different sources of irrigation water. The values of SAR ranged from 0.79 in borewell irrigated soils to 18.43 in lift irrigated soils. Most of the studied soils (131 samples) were found to be safe from sodicity hazard with < 10 SAR values. In terms of RSC of soils ranged from -23.20 meq/l in lift irrigated soils to +11.70 meq/l in dryland soils. Majority of the black soils of Mudhol taluka (70.6 %; 101 samples) were found safe with low RSC values (< 1.25 meq/l) while, 23.8 per cent of the samples recorded higher RSC of > 2.5 meq/l.Keywords

An investigation was carried out to study the micronutrients status in soils of chilli grown areas of UKP command at College of Agriculture, Raichur, during the year 2006-07. The concentration of iron and manganese in soil samples collected before the crop season ranged from 3.95 to 4.95 ppm and 23.03 to 25.87 ppm, respectively and their concentration increased after the harvest of the crop. Similarly, the soil samples of experimental sites recorded moderate levels of micronutrients did not vary significantly but the soil supplemented with organic manures (Category-2 and category-4) recorded higher levels of micronutrients compared to no organic manure added chilli cultivated soil samples (Category-3).Keywords

Physically degraded lands are characterized with high graveliness and low nutrient status resulting in sparse vegetation hence, external supplementation of nutrients is essential for successful vegetation establishment. The soil pH and EC was similar to that of normal soil in degraded lands. However, the organic carbon and nutrient status were low in wastelands with higher BD of 1.62 gcc-1. The evaluation of different organic wastes such as paper mill sludge, sugar mill sludge, distillery sludge and municipal sludge along with FYM as a nutrient source for degraded lands reveled that N and P content was highest in sugar mill sludge followed by municipal sludge while K content and secondary nutrients such as calcium and sulphur were found highest in distillery sludge. In case of micro nutrients high levels of Fe (1550 ppm) and Mn (407 ppm) was observed in paper mill and sugar mill sludge, respectively. The Zn (2329 ppm) and Cu (448.4 ppm) were recorded in municipal sludge. The different organic sources were rated as sugar mill sludge, municipal sludge, distillery sludge, FYM, paper mill sludge.Keywords

A field experiment was conducted during Rabi 2010-11 in the Hassan district of Karnataka with the objective to study the influence of foliar application of secondary and micro nutrients on yield and quality of tomato. Tomato was grown in plots of 6×3 m2 size with nine different treatments in RCBD layout with 3 replications in a red sandy loam soil with slight alkaline pH. The foliar nutrition and soil amendment applications along with NPK fertilizers increased fruit weight significantly. Treatments receiving major nutrients and foliar sprays of secondary and micronutrients (T2 - 2.34 kg plant-1 and T6 - 2.89 kg plant-1) recorded slightly higher yield compared to T1 (2.22 kg plant-1) and T5 (2.30 kg plant-1). Treatment combinations of major nutrients, foliar sprays and soil amendment recorded the highest number of flowers and fruits in both UAS package and IIHR technology treatments. The shelf life of tomato increased with foliar spray and amendment applications (12-16 days) compared to major nutrients alone (9-11 days). The fruits from plots receiving all the three combinations recorded significantly higher TSS, acidity and ascorbic acid content. The quality parameters like TSS, ascorbic acid and acidity of tomato fruits in UAS package received plots was of the order T4 > T3 > T2 > T1. The trend remained similar with IIHR technology (T8 > T7 > T6 > T5). The plots receiving nutrients as per farmers practice produced lesser number of flowers and fruits. The fruit size and the yield was also lesser. Many of growth and yield parameters were found at par with T1 and T5 treatments. It was observed from the current study that the IIHR based treatments with foliar application of secondary and micronutrients and splits of N and K was better for increasing productivity.Keywords

Hassan and Belur taluks are the major tomato growing areas in the district and hence, this study was restricted to these two talukas. Surface soil samples from a depth of 0-15 cm were collected from 80 tomato-grown plots. Study revealed that the soil pH ranged from neutral to alkaline range (6.9-8.5) while, the electrical conductivity was in the range of 0.05 to 0.95 dS m-1. The soil organic-C content varied to a large extent 1.3 to 12.8 g kg-1. The soil organic-C content was low in more than 50 per cent of tomato soils. The available nitrogen content ranged from 205.0 to 376.3 kg ha-1. More than 70 per cent of tomato fields were found low in nitrogen. In contrast, both available phosphorus and potassium contents were found higher in majority of tomato grown soils. The available phosphorus was found high in almost all soils. Similarly, the available potassium content was higher in 90 per cent plots. None of the tomato grown soils were found lower in calcium while, 9 per cent of the fields recorded magnesium in lower. The available sulfur content was low in almost 68 per cent of tomato soils (5.6 ± 2.5 mg kg-1) and only 9 per cent of fields recorded higher sulphur content. The DTPA-Fe, Mn, Cu and Zn were found higher in 93, 91, 57 and 68 per cent of the tomato grown soils, respectively.Keywords
