Anand Agricultural University, Anand

Anand Agricultural University (AAU) was established in 2004 at Anand with the support of the Government of Gujarat, Act No.(Guj 5 of 2004) dated April 29, 2004. Caved out of the erstwhile Gujarat Agricultural University (GAU), the dream institution of Sardar Vallabhbhai Patel and Dr. K. M. Munshi, the AAU was set up to provide support to the farming community in three facets namely education, research and extension activities in Agriculture, Horticulture Engineering, product Processing and Home Science. At present there seven Colleges, seventeen Research Centers and six Extension Education Institute working in nine districts of Gujarat namely Ahmedabad, Anand, Dahod, Kheda, Panchmahal, Vadodara, Mahisagar, Botad and Chhotaudepur AAU's activities have expanded to span newer commodity sectors such as soil health card, bio-diesel, medicinal plants apart from the mandatory ones like rice, maize, tobacco, vegetable crops, fruit crops, forage crops, animal breeding, nutrition and dairy products etc. the core of AAU's operating philosophy however, continues to create the partnership between the rural people and committed academic as the basic for sustainable rural development. In pursuing its various programmes AAU's overall mission is to promote sustainable growth and economic independence in rural society. AAU aims to do this through education, research and extension education. Thus, AAU works towards the empowerment of the farmers.

    PHYTOSTABILIZATION OF LEAD IN SOIL THROUGH FYM UNDER FODDER MAIZE
    (AAU, Anand, 2015) MALI, ROHITKUMAR HARESHBHAI; Patel, S. B.
    A pot experiment was conducted during rabi season of 2014-15 in the net house of the Micronutrient Research Project (I.C.A.R), Anand Agricultural University, Anand to carry out the study on "Phytostabilization of lead in soil through FYM under fodder maize". The pot experiment was laid out in a completely randomized design (factorial) with three replications. Total twenty treatments comprising of five levels of Pb (0, 50, 100, 150 and 200 mg kg-1) and two levels of FYM (0 and 20 t ha-1) and two varieties (GM-3 and African tall) of fodder maize, were evaluated to study their effect on germination count, plant stand, plant height, green forage and dry matter yield as well as lead availability and nutrient content (P, S ,Fe, Mn, Zn and Cu) and soil properties (EC, pH, OC, S, DTPA-Fe and Zn) at the time of harvest. The experimental results indicate that with increasing Pb levels, significant decrease in the plant height (cm) at 15, 30, 45 and 60 DAS, green forage yield (g pot-1) and dry matter yield (g pot-1) of whole plant of maize was noted. The yield reduction started at lower level of Pb (50 mg kg-i soil) and reduction was rfiaximum when 200 mg kg-1 Pb was applied to soil. Significantly the highest green forage yield (71.03 g pot-1) was recorded under Pbo x F1 treatment. Among all treatment combinations, PboF1 recorded maximum dry matter yield (15.97 g pot-1), whereas the minimum yield (6.24 g pot-1) was noted under Pb2ooFo treatment combination. With increasing rates of Pb application, Pb content in shoot and root of maize was found to increase at 30 DAS and 60 DAS, whereas P, S, Fe, Mn, Zn and Cu were decreased in shoot and root of both the varieties at 60 DAS. The application of Pb from 0 to 200 mg kg-1 gave significantly higher Pb content in leaf at 30 DAS from 0.47 to 27.86 mg kg-1, 0.63 to 36.47 mg kg-1 in shoot and 0.86 to 83.11 mg kg-1 in roots. The application of Pb significantly increased EC and decreased pH value of soil. The Pb application increased DTPAPb of the soil with increasing rates of Pb. The OC, available S, DTPA- Fe and Zn were decreased with increasing rates of Pb to the soil. The highest value of Pb (46.16 mg kg-i) was found wherein Pb was applied at 200 mg kg-1. Addition of FYM @ 20 t ha-1 increased all nutrients contents in plant components except lead content. Yield parameters like plant height (cm) and plant stand at 15, 30, 45 and 60 DAS , green forage yield (g pot-1) and dry matter yield (g pot-1) of fodder maize were found to increase with the application of FYM @ 20 t ha-1 over no FYM. With the application of FYM @ 20 t ha-1, Pb content in shoot and root of maize was found to decrease at 30 DAS and 60 DAS, whereas P, S, Fe, Mn, Zn and Cu contents were increased in shoot and root of both the varieties at 60 DAS over no FYM. Addition of FYM @ 20 t ha-1 increased EC and OC, while decreased soil pH and it had reduced the availability of Pb in the soil and significantly increased all nutrients viz., S, OC, Fe and Zn status in soil after harvest of crop. Interaction effect of FYM x Pb was found to be significant with respect of green fodder yield, dry matter yield, micronutrient contents Viz., Fe, Mn, Zn and Cu as well as P2O5 and S content. Growth and yield attributes, micronutrients and major nutrients were decreased with increasing levels of Pb but application of FYM @ 20 t ha-i increased nutrient content in plant and increase in growth and yield with respect to Pb content in plant. DTPA-Pb in soil was increased with increasing levels of Pb but application of FYM @ 20 t ha-i reduced the content and availability of Pb. The findings of the present study reveal that application of FYM @ 20 t ha-1 had significant mitigating effect on lead toxicity as it reduced its availability due to stabilization in soil. Between two varieties variation in stabilization of lead in plant was not large. The incubation result revealed that over the period, DTPAPb was reduced at each level of applied Pb, the maximum reduction of 28.2 per cent was recorded in case of Pb200 at 42nd day over 0 day. The application of FYM @ 20 t ha-1 showed fixation of lead to the extent of 2.2 per cent under Pb20o over no FYM application.
