Field experiment was conducted in sodic soil (pH 8. 9 ESP- 31.5 %) to study the extent of reclamation achieved due to basal application of raw spentwash (RSW) and to study the effect of primary spentwash (SW) used for ferti-irrigation on extent of reclamation incidentally achieved due to spentwash application in comparison with gypsum and also on growth and yield of paddy. Highest grain, straw yield and nutrient uptake was recorded in RSW @ 100 % GR+100 % RDN through SW (3 splits) and lowest was recorded in T1 which received gypsum @50 % GR + recommended NPK. Per cent increase in grain yield 47.34 per cent (T9) was noticed in spentwash amended plot compared to gypsum treatment (T1). Reduction in soil pH was highest in T9 (RSW @ 100% GR+100% RDN through SW (3splits)) and lowest in T1 (Gypsum@50% GR+ Rec.NPK). Application of RSW @ 100% GR+100% RDN through SW (4 splits) recorded significantly lower exchangeable sodium content and ESP compared to other treatments. The cost economics of cultivation revealed that highest benefit cost ratio (2.69) was obtained with raw spentwash @ 100 % GR+ 100 % RDN through treated spentwash in 3 splits while the lowest 0.53 was with gypsum @ 100 % GR+ rec.NPK.Keywords

The field experiment was conducted at farmer's field with the application of human and cattle urine as liquid fertilizer or nutrient sources on ashgourd [Benincasa hispida (Thunb.) Cong.], French bean (Phaseolus vulgaris L.), pole bean (Phaseolus vulgaris L.) and pumpkin (Cucurbita maxima) as test crops at Nagasandra village, Doddaballapur, Bangalore rural district from 2009 to 2011. The objective of the study was to know the effect of repeated application of human urine and cattle urine on soil properties and yield of vegetable crops. Application of recommended dose of nitrogen through human urine in three split doses plus gypsum recorded higher yield (39.2,14.2, 17.4 and 38.7 t ha-1, for ashgourd, French bean, pole bean and pumpkin, respectively) and it was at par with recommended dose of nitrogen through cattle urine in three splits plus gypsum (T14: 38.0, 14.1, 16.6 and 37.5 t ha-1, for ashgourd, French bean, pole bean and pumpkin, respectively) and recommended dose of fertilizers (T2: 36.7, 13.7, 15.8 and 36.8 t ha-1, for ashgourd, French bean, pole bean and pumpkin, respectively). Significantly higher primary, secondary and micronutrient content in soil were recorded with recommended dose of nitrogen through human urine in three split doses plus gypsum at harvest of ashgourd crop. The trend of variation in available nitrogen, phosphorus and potassium content of soil recorded at harvest of ashgourd was retained in subsequent seasons when French bean, pole bean and pumpkin crops were grown in sequence after ashgourd crop in the same plots receiving same treatments.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

The large quantities of organic wastes (sludges) generated by industries are plant nutrients. Thus in point of national development, safe disposal of these wastes play a major role. On other hand, rising of sapling in forest nursery has been incurred large production cost due to higher nutrient demand. Thus, nutrient rich organic wastes provide an opportunity to utilize them as nutrient source in place of conventional organic manures. In this context, an attempt was made to utilize nutrient rich organic wastes as source of manure in forest nursery. The various organic wastes collected from different sources were analyzed for their nutrient content. The organic wastes were mixed in the ratio of 1:1:1 and 1:1:2 of sand:soil:organic wastes and then filled into polyethylene bags. Two months native saplings of Acacia auriculiformis, Pterocarpus marsupium, Azadirachta indica, Holoptelea integrifolia and Tectona grandis were planted and growth parameters were monitored at monthly interval. The plants growth varied significantly due to application organic wastes at both the level. The growth was influenced by the wastes in the order of distillery sludge > municipal sludge > sugar mill sludge > FYM > paper mill sludge. In general the wastes at higher level recorded higher growth compared to that of lesser rate. Among the different species selected for the study the height (cm), collar diameter (mm) and bigmass (g) was measured in the order-Azadirachta indica > Acacia auriculiformis > Tectona grandis > Holoptelea integrifolia > Pterocarpus marsupium. The overall results suggest that the sewage sludge and agro industrial wastes can be effectively and efficiently used for raising of forest nursery.Keywords

A field experiment was conducted during Kharif 2015 in a farmer’s field to study the effect of foliar spray of humic acid fortified with zinc and boron on growth and yield of capsicum. The experiment was laid out in Randomized Complete Block Design with 16 treatment combinations. The results revealed that significantly higher plant height, total number of branches plant-1, number of leaves per plant-1, SPAD meter reading, dry matter production plant-1, Number of fruits plant-1, yield plant-1, per cent fruit set, weight of ten fruits, fruit yield (54.23 t ha-1) were recorded in treatment receiving RDF+FYM applied to soil and 3 foliar sprays of zinc fortified humic acid extracted from poultry manure at 0.50 per cent and it was at par with the treatment receiving RDF+FYM applied to soil and 3 foliar sprays of zinc fortified humic acid extracted from coffee pulp at 0.50 per cent.Keywords

Study was undertaken in Western Ghats and Coastal area in Karnataka state, India with the aim of evaluating the fertility status of soils using nutrient index approach, mainly for primary nutrients. Based on fertility ratings, pH of soils was strongly acidic to moderately acidic. Electrical conductivity was normal (<1.0 dS m-1). Soil organic carbon was medium to high. Primary nutrient status i.e., N, P and K were low in >60 % samples. Whereas, >80 % of samples were low in exchangeable Ca, Mg and available S content. Among the micronutrients Cu and B were found to be low in >70% of samples, whereas Fe, Mn and Zn were adequate in >85 % of samples. Nutrient index value for major nutrients (available N, available P and available K) was found to be low (<1.67 range).Keywords
