The present study on adoption of soil test recommendations by the farmers was conducted in the year 2015?16 in Chandur Bazar and Bhatkuli tehsils of Amravati district. For this study 100 respondents were selected with the help of random sampling method. The data were collected with the help of structured interview schedule. Collected data were carefully examined, classified quantified and tabulated. Frequencies, mean, standard deviation, correlation of coefficient analysis were employed for interpreting the results. Results obtained after analysis have been summarized as below. The findings of the present investigation indicate that near half 47.00 per cent of the respondents were in old age group and 38.00 per cent respondents were educated upto high school level. More than one third of respondents 35.00 per cent had small land holding upto 1.01-2.00 ha. 33.00 per cent respondents had annual income in between Rs. 50,000 to 1,00,000. Over half 52.00 per cent of the respondents having medium level of extension contact. The 71.00 per cent respondents having no source for irrigation availability. 82.00 per cent respondents were taking seasonal crops. The 59.00 per cent of respondents were having low level of motivation. 41.00 per cent of respondents were having medium level of innovativeness towards adoption of soil test recommendations. 52.00 per cent of the respondents were having medium level of availability of fertilizers. The majority of respondents 48.00 per cent had high understanding about soil test recommendations, only 34.00 and 18.00 per cent of the respondents having medium and low understanding about soil testing, respectively. The most of the respondents 76.00 per cent were having low level of adoption about soil test recommendations, only 19.00 per cent respondents were having medium adoption level and 5.00 per cent respondents were having high level of adoption of soil test recommendations. In the study it was found that education, annual income, extension contact, cropping pattern, motivation, innovativeness, availability of fertilizers and understanding of soil test recommendations were positive and significantly related with adoption at 0.01 level of significance and irrigation availability was positivey and significantly related with adoption at 0.05 level of significance. Age and land holding were found to be non-significantly related with adoption. Lack of knowledge about nutrient management, soil test report not clear to the respondents had major constraints.

Soil survey was carried out during 2014 in Shirpur tehsil of Dhule district (M.S.), India by using global positioning system (GPS) and geographical information system (GIS). Soil samples were analyzed for pH, EC, OC, CaCO3 and available micronutrients viz., Fe, Mn, Zn, Cu, B and Mo. The availability of macronutrients, micronutrients and their relationship with soil properties were also studied. The soil pH varied from 6.7 to 8.4 with mean value of 7.6 and indicated that slightly to moderately alkaline in reaction. The soil EC varied from 0.10 to 0.82 dSm-1 (mean 0.28 dSm-1) and indicated that 100 per cent soils are non-saline in nature. The organic carbon and calcium carbonate ranged from 3.9 to 8.2 g kg-1 and 7.0 to 17.75 per cent with mean value of 6.12 g kg-1 and 12.28 per cent, respectively. The soils of Shirpur tehsil are low to high in organic carbon and high to very high in calcium carbonate content. The available micronutrients Fe, Mn, Zn, Cu, B and Mo ranged from 1.19 to 14.8, 2.02 to 5.88, 0.13 to 1.58, 0.27 to 3.98, 0.16 to 1.48 and 0.06 to 0.39 mg kg-1 with mean of 4.09, 2.78, 0.71, 2.32, 0.61 and 0.18 mg kg-1, respectively. The soils of Shirpur tehsil were deficient in available iron (49.76%), available zinc (33.82%) and available boron (27.05%). The available Fe, Mn, Zn, Cu and B showed negative significant correlation and available Mo showed positive significant correlation with pH. Available Mn and Cu showed positive significant correlation with organic carbon. A negative significant correlation of available Cu with calcium carbonate was observed.

Volume: 11 | Issue no: 2-2016 | Pagination: 348-352
An experiment was conducted with rice (cv. GOTRA BIDHAN - 1) in soils of Terai alluvial situation of West Bengal during the Rabi season of 2009-2010 to find out the effect of some primary (N-P-K) and micro (Zn-B) nutrients along with organic matter on the variability of yield of rice. The treatments were based on the soil-test based fertilizer recommendation . The average grain and straw yield of rice varied from 2.28 to 4.31 t ha-1 and 3.12 to 4.67 t ha-1, respectively. Maximum grain yield of rice was obtained at the optimum application of the given nutrients. Omission of nutrients from the optimum, caused yield losses from 9.9 to 47.1 per cent. The yield data also revealed that N-P-K-Zn and B were the main limiting factors under the present experimental set-up. The results suggested the need for applying the given nutrients at optimumlevels for the successful yield maximization programme.

Author:Jeena Mathew And Sumam George
Volume: 11 | Issue no: 2-2016 | Pagination: 318-323
Sulphur and boron have been found to act in a synergistic manner for enhancing the yield and quality of sesame (Sesamum indicum L.). As it is the choice crop of farmers in the summer rice fallows of Onattukara, field experiments were laid out in factorial RBD with four levels each of sulphur and boron with the variety Thilarani. The levels of sulphur tried were 0 kg S ha-1, 7.5 kg S ha-1, 15.0 kg S ha-1 and 30.0 kg S ha-1 and 0 kg B ha-1, 2.5 kg B ha-1, 5.0 kg B ha-1 and 0, 2.5, 5.0 and 7.5 kg B ha-1 for boron which were applied as gypsum and borax, respectively. The incubation study, designed to understand the release pattern of nutrients reveled that highest quantity of sulphur and boron were available during the 30th day of incubation and there after showed a decreasing trend. Application of sulphur @ 30 kg ha-1 and boron @ 7.5 kg ha-1improved the available nutrient status of Onattukara soil. The nutrient use efficiency of sulphur was highest at 30 kg ha-1 and that for boron it was 2.5 kg ha-1. It also registered a significant positive impact on enhancing the yield and yield attributes of sesame in such a way that the highest rates of both the nutrients registered maximum yield from the crop in both the years.

A field experiment was conducted to evaluate the effect of phosphorus, sulphur and phosphate solubilizing bacteria on growth and nutrient uptake by mustard [Brassica juncea (L.) Czern and Cosson.] grown in loamy sand soil. The experimental soil has pH 7.60 and was deficient in available sulphur and nitrogen and medium in available phosphorus. The experiment was tested by Randomized Block Design with four replications. The treatments comprised of three levels each of phosphorus (0, 25, 50 kg P2O5 ha-1) and sulphur (0, 20, 40 kg S ha-1) and two levels of phosphate solubilizing bacteria (PSB) inoculation (no inoculation and inoculation with Aspergillus niger strain-1). The results of the experiment revealed that each successive increase in level of phosphorus significantly increased the crop growth and uptake of nutrients. Different levels of sulphur significantly improved the growth, yield as well as uptake of nutrients by seeds and straw of mustard. Seed inoculation with PSB (I1) significantly increased yield, uptake in seed and straw and availability of nutrients in soil. Combined effect of 50 kg P2O5 ha-1 and 40 kg S ha-1 with seed inoculation with PSB gave higher seed and straw yield as well as nutrient content in seed and straw which resulted in higher nutrient uptake by mustard grown in loamy sand of North Gujarat.

Vegetables are the integral part of the balanced diet of human since time immemorial. Globally, the role of vegetables has been recognized in solving the problem of food and nutritional security. A survey conducted to assemble baseline information on farming practices to cabbage production in peri-urban area of Saharsa district.Structured questionnaires used to elicit information from cabbage farmers, where cabbage is intensively produced. The level of education among the growers was low as only 6.67 per cent had secondary education. Majority of the growers (68%) did not own the lands, thus, resulting in approximately 65 per cent of them cultivating less than one acre of cabbage. Majority of cabbage farmers (61.67 %) planted cabbage on raised beds. Cabbage production was characterized by high use of inorganic fertilizer (NPK). Seventy-three per cent farmers employed the watering cans in cabbage production. Farmers in their quest to mitigate the high insect pest infestation and problems such as wilting of plants, leaf curl and leaf spots resorted to high frequency of pesticides application. The information gathered from this study would form the basis for the formulation of an integrated pest management (IPM) as well as integrated nutrient management (INM) strategy to enhance environmentally sustainable production of cabbages. This would reduce environmental degradation and ensure maximum protection for human well being.
