Sole pearlmillet and their intercropping combinations during kharif followed by wheat grown with three nitrogen levels i.e 50, 75 and 100 % of recommended dose of nitrogen (RDN) to identify the profitable system. Based on two year study the net return and B:C ratio under Sesbania-wheat rotation were 17.9% and 7.1% more over pearlmillet-wheat crop rotation, respectively. Among intercropping systems Sesbania sown at 90 cm spacing intercropped with one row of pearlmillet followed by wheat was the most profitable crop rotation for the farmers who are interested in seed crop of sesbania with net return (Rs 40013/ha) and B:C ratio (1.48) along with highest Sesbania seed yield of (924kg/ha) with an additional pearlmillet yield (743kg/ha) and wheat equivalent yield (6656kg/ha). Sesbania sown at 120 cm spacing intercropped with two rows of pearlmillet followed by wheat was the most profitable crop rotation for farmers, who are more interested in pearlmillet seed crop with the highest net return ( Rs 40593/ha) and B:C ratio (1.48) along with highest pearlmillet seed yield (1344 kg/ha), Sesbania seed yield (762 kg/ha), highest sesbania equivalent yield (1379 kg/ha) and second highest wheat equivalent yield (6661kg/ha) among intercropping systems. So, Sesbania followed by wheat is more profitable over pearlmillet-wheat crop rotation and from sustainability point of view to encourage the farmers for seed production of Sesbania and to get maximum net return, the Sesbania can be intercropped with one or two rows of pearlmillet. Sesbania sole or in combination with pearlmillet as intercrop was found beneficial for soil health improvement in terms of available N,P and K status of soil as compared to pearlmillet sole-wheat rotation.
A pot experiment was conducted to evaluate the effect of amendments on phytoextraction of chromium using cyclohexanediaminotetraacetic acid, citric acid, diethylenetriamine-pentaacetic acid, nitrilotriacetic acid (at 3 mmol kg -1 soil) and farmyard manure (at 3 %) with Brassica juncea in the sewage sludge unamended and amended (at 3 %) soil. Application of chelating agents influenced dry matter yield and uptake of chromium by roots and shoots differentially depending upon the nature of the chelating agents. Dry matter yield of roots and shoots of Brassica juncea increased due to application of nitrilotriacetic acid, citric acid and farmyard manure whereas reverse trend was observed in cyclohexanediaminotetraacetic acid and diethylenetriamine-pentaacetic acid treated soils. Addition of sewage sludge at 3 % on dry weight basis was found beneficial in improving the plant growth. Chelating agents enhanced the chromium uptake by both roots and shoots and significantly higher values of chromiumuptake by roots and shoots were observed from amended as compared to sewage sludge unamended soil. Application of nitrilotriacetic acid was found more effective in enhancing the chromium uptake by Brassica juncea roots and shoots than any other chelating agents at both the growth stages. The chelating agents are found useful in enhancing phytoextractability of chromium by Brassica juncea. Hence, marginally chromium contaminated soil may be remediated by adding chelating agents.
A study was carried out to evaluate the pedological development of soils in Eastern agroclimatic zone of Haryana using field morphology rating system. For this, nine pedons were excavated to study the morphological properties in field and rating scale was used to compare adjacent horizons with each other to give a comparison of the relative distinctness of horizons or to compare horizons in the solum with the C-horizon to give a relative profile development in soils occurring in different physiographic positions i.e. Shiwalik hills, recent and old alluvial plains with different precipitations throughout the study area. Some chemical properties were also used to evaluate the pedogenic factors as a result of being affected by process and factors of soil formation due to the distinct effect of climate. The Relative Horizons Distinctness (RHD) ratings were made by a comparison of adjacent horizons. The soils of Shiwalik hills, recent and old alluvial plains have RHD ratings from 6 to 14, 3 to 11 & 3 to 12, respectively. The RPD ratings were made by a comparison of the C horizon to the horizons above it in the profile. The soils of Shiwalik hills, recent and old alluvial plains have RPD ratings from 7 to 15, 3 to 14 & 5 to 16. The RPD values of all the profiles were maximum in A horizon due to maximum pedological development influenced by weathering. So, studies of these soils indicated the pedological development in the order of Shiwalik hills > old alluvial plains > recent alluvial plains.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
