To increase the production of medicinal senna in sandy soils of coastal agro ecosystem, integrated nutrient management treatments involving inorganic fertilizers, organic manures namely FYM, vermicompost, humic acid and microbial consortium were evaluated. The intial soil was typic udipsamments and represented sandy texture and non-saline nature. In Completely Randomized Design, the following treatments were evaluated with three replications using senna as test crop. T1 - Absolute control, T2 - Recommended NPK, T3 - FYM alone @ 12.5 t ha-1, T4- Vermicompost alone @ 4.0 t ha-1, T5- 75 % NPK + FYM @ 12.5 t ha-1, T6 - 50 % NPK + FYM @ 12.5 t ha-1, T7 - 75 % NPK + vermicompost @ 4.0 t ha-1, T8 - 50 % NPK + vermicompost @ 4.0 t ha-1, T9 - T5+ ZnSO4 @ 25 kg ha-1 + humic acid foliar spray @ 0.3 %, T10-T6 + ZnSO4 @ 25 kg ha-1 + humic acid foliar spray @ 0.3% , T11 - T7+ ZnSO4 @ 25 kg ha-1 +Humic acid foliar spray @ 0.3% , T12 - T8+ ZnSO4 @ 25 kg ha-1 + humic acid foliar spray @ 0.3% . Bio inoculants, Azospirillum and phosphobacterium were applied to all the treatments excluding absolute control and recommended NPK. The results of the study indicated that the application of INM significantly improved the growth and yield of senna in coastal sandy soil. Among the treatments, application of 75 % NPK fertilizer + vermicompost @ 4.0 t ha-1 + ZnSO4 @ 25 kg ha-1 with humic acid foliar spray ranked best in recording the higher growth character, leaf and pod yield of senna and available soil nutrients.Keywords

Zinc deficiency associated reduction of yield is well known in coarse textured sandy soils. A pot experiment was carried out in the Department of Soil Science and Agricultural Chemistry, Annamalai University with groundnut var. VRI 2 during June-September 2006, to evaluate different levels of zinc on the yield and nutrients uptake by groundnut in coastal sandy soil. The experimental soil was sandy, taxonomically classified as Typic udipsaments with pH-8.39; EC-1.61 dS m-1 and represented low status of organic carbon and zinc. The following treatments studied: T1- NPK; T2- NPK + ZnSO4 @ 20 kg ha-1; T3- NPK + ZnSO4 @ 25 kg ha-1; T4- NPK + ZnSO4 @ 30 kg ha-1 and T5- NPK + ZnSO4 @ 35 kg ha-1. All the treatments received a common organic addition of composted coirpith @ 12.5 t ha-1. The experiment was arranged in a Completely Randomized Design (CRD) with four replications. The experimental results revealed that, the application of NPK + ZnSO4 @ 30 kg ha-1 was significant in increasing the nutrients uptake and yield of groundnut. The percentage yield increase recorded with ZnSO4 application @ 30 kg ha-1 along with CCP was 15.25 percentage of pod and 15.81 percentage of haulm yield as compared to control.Keywords

In determining the yield and quality of groundnut, the role of Zn and B is much pronounced. Restricted availability of these nutrients in sandy soil greatly impairs the yield of groundnut. A field experiment was conducted to find out the effect of micronutrients viz., Zn and B on the yield and nutrients uptake by groundnut in coastal sandy soil. The experiment was carried out in a farmer's field at Ponnanthittu village in Cuddalore district, Tamil Nadu during December-March 2007. The initial fertility status of experimental soil was pH 8.39, EC-1.61 dSm-1, organic carbon 2.7g kg-1 and represented low status of micronutrients. The various treatments included were T1- Control, T2- 100% NPK, T3- 150% NPK, T4- 150% NPK + ZnSO4 @ 30 kg ha-1, T5- 150% NPK + Borax @15 kg ha-1, T6- 150% NPK + ZnSO4 @ 30 kg ha-1 + Borax @15 kg ha-1 along with composted coirpith @ 12.5 t ha-1. The experiment was carried out in a Randomized Block Design (RBD) with four replications, using groundnut variety VRI 2 as test crop. The results clearly indicated that, T6- 150% NPK + ZnSO4 @ 30 kg ha-1 + Borax @ 15 kg ha-1 along with composted coirpith application significantly increased the yield and nutrients uptake by groundnut. This treatment recorded the highest pod yield of 2466 kg ha-1 and haulm yield of 3354 kg ha-1 which represented 31.31 and 25.95 per cent increased in pod and haulm yield, respectively over 100 per cent NPK application.Keywords

A field experiment was conducted in the farmer’s field during January-April 2015, to study the effect of vermicompost and micronutrients fertilization on the growth, yield and nutrients uptake by sesame in coastal saline soil. Texturally, the experimental soil was sandy and taxonomically classified as Typic Udipsamments with initial soil characteristics (0-15 cm layer) of the experimental site were, pH-8.37 and EC-1.58 dS m-1. The soil registered low organic carbon status of 2.31 g kg-1, 134.56 kg ha-1 of alkaline KMnO4-N; 9.43 kg ha-1 of Olsen-P and 159.31 kg ha-1 of NH4OAc-K, respectively. The DTPAextractable Zn and Mn was 0.69 mg kg1 and 0.94 mg kg-1, respectively. The various treatments imposed in the study included T1-Control (RDF alone), T2-RDF+vermicompost (VC) @ 5 t ha-1, T3-RDF+ZnSO4 @ 25 kg ha-1 soil application (SA)+MnSO4 @ 5 kg ha-1 (SA), T4-RDF+ZnSO4@ 0.5% foliar application (FA)+MnSO4 @ 0.5% (FA), T5-RDF+(ZnSO4+MnSO4) SA+(ZnSO4+MnSO4) FA, T6-RDF+VC (ZnSO4+MnSO4) SA, T7-RDF+VC+(ZnSO4+MnSO4) FA, T8-RDF+VC+(ZnSO4+MnSO4) SA+(ZnSO4+MnSO4) FA, T9-RDF+VC+(50% ZnSO4+50% MnSO4) SA and T10-RDF+VC+(50% ZnSO4+50% MnSO4) SA+(ZnSO4+MnSO4) FA @ 0.5 per cent. The experiment was carried out in a Randomized Block Design (RBD) with three replications and tested with sesame var. TMV 7 as test crop. The results of the study clearly indicated that the combined application of RDF+VC+50% recommended ZnSO4 @ 12.5 kg ha-1+50% MnSO4 @ 2.5 kg ha-1 through soil application along with foliar spray of ZnSO4+MnSO4 twice @ 0.5 per cent significantly increased the growth, yield and nutrient uptake by sesame. This treatment recorded the highest seed and stalk yield of 792 kg ha-1 and 1713 kg ha-1 which was 45.32 and 36.77 per cent increased seed and stalk yield, respectively over recommended dose of fertilizer alone (RDF).Keywords

To find out the effect of different levels and sources of zinc fertilizers on the growth and yield of okra in coastal sandy soil, a pot experiment was carried out in the department of Soil Science and Agricultural Chemistry, Annamalai University during January-April 2014. The texture of the soil was sandy and taxonomically classified as Typic usticpsamments with pH-8.32, EC-1.54 dS m-1 and represented low status of organic carbon (2.30 g kg-1). The soil had low alkaline KMnO4-N (134.50 kg ha-1), low in Olsen- P (9.48 kg ha-1) and medium in NH4OAc-K (178.20 kg ha-1). The available Zn (DTPA extractable Zn) content was 0.71 mg kg-1 in soil. The sixteen treatments consisted of four levels of zinc viz., 0, 10, 15 and 20 mg kg-1 Zn as factor-A and three different sources of zinc fertilizers viz., control, zinc sulphate (ZnSO4), Zn-EDTA and Zn-Humateas factor-B. The experiment was laid out in a Factorial Completely Randomized Design (FCRD) with three replications using okra variety MBH-64 as test crop. The results revealed that the combined application of Zn @ 15 mg kg-1 through Zn-Humate (A2B3) significantly increased the growth, yield characters and yield of okra.Keywords

A field experiment was conducted to evaluate the effect of liquid biofertilizer Symbion N (Azospirillum) and Symbion P (Phosphobacter) on the growth and yield of okra. The experiment was laid out in Annamalai University experimental farm in clay loam soil during summer 2006. The treatments studied were T1-Symbion N (foliar), T2-Symbion P (soil), T3-Symbion-N (foliar)+Symbion P (soil), T4-Symbion N+Symbion P (soil) and T5-control. All the treatments were replicated three times in RBD. A fertilizer schedule of 40:50:30 kg N:P2O5:K2O/ha was applied to all the treatments. The foliar application of Symbion N was followed @ 250 ml/ha and sprayed at 10 days after sowing and another at flowering. The soil application of liquid formulations was carried out @ 250 ml/ha applied one at 10 days after sowing and another at flowering. Okra variety Parbani Kranti was sown as test crop. The results of the study indicated that application of liquid bio-fertilizer both Symbion N and Symbion P significantly increased the growth character, yield character and yield of okra. Among various treatments, Symbion N and Symbion P both applied in soil was significantly superior in increasing the growth and yield of okra. This treatment recorded the highest okra yield of 6280 Kg ha-1.Keywords

In an incubation experiment, the changes in physio-chemical properties and the periodical release of nutrients with fortified organic manures to a coastal saline sodic soil was studied. The experimental soil was collected from the farmer’s field at Sillankuppam village, Cuddalore district. The FeSO4+ZnSO4 fortified green leaf manure and coir pith significantly exerted a favourable effect on reducing the salinity and sodicity and increasing the availability of major and micronutrients in soil. Among the organics, micronutrients fortified green manure was associated with the greatest improvement in physio-chemical properties and nutrient availability.Keywords

A pot experiment was conducted at the Department of Soil Science and Agriculture Chemistry, Annamalai University, Tamilnadu during 2008-2009 to study the fertilizer requirement of Catharanthus roseus in coastal sandy soil. The soil was classified as typic Udipsaments and had deficient level of N, P and K. The growth parameters of Catharanthus rose us viz., plant height, number of branches per plant, number of leaves per plant were influenced favorably with increasing level of NPK application. A reduction in NPK application reduced the yield parameters and leaf yield significantly. The result revealed that the application of NPK @ 30: 40: 40 kg ha-l proved to be optimum as it recorded the maximum growth characters like plant height (97.50 cm), number of branches per plant (10.75) and dry weight of leaves (24.54 g/plant) and dry weight of ischolar_main (8.46 g/plant).Keywords

A field experiment was conducted to find out the effect of organic manure fortified with micronutrients viz., ZnSO4 and FeSO4 on the growth and yield of rice in coastal saline soil. The experiment was conducted in farmers field at Sillankuppam village in Cuddalore district, Tamil Nadu during October-January 2009. The initial fertility status of experimental soil was pH-8.88, EC-2.16 dS m-1 and OC-0.22 g kg-1 and represented low status of micronutrients. The treatments were T1–Recommended level NPK, T2-NPK+ZnSO4+FeSO4 @ 25 Kg ha-1, T3-NPK+Green manure fortified ZnSO4+FeSO4 @ 75% RL, T4-NPK+Green manure fortified ZnSO4+FeSO4 @ 100% RL, T5-NPK+Green manure fortified ZnSO4+FeSO4 @ 125% RL, T6-NPK+Coir pith fortified ZnSO4+FeSO4 @ 75% RL, T7-NPK+Coir pith fortified ZnSO4+FeSO4 @ 100% RL, T8-NPK+Coir pith fortified ZnSO4+FeSO4 @ 125% RL. The results showed that, micronutrients fortified composted green leaf manure significantly increased the growth and yield parameters of rice as compared to other treatments.Keywords
