Crops need large quantity of potassium for enhancing their yield as well as quality. Pulses are important crops grown in India but their productivity is low. Among production inputs, recommendations for N and P fertilizers are made in most states with no K application resulting in imbalanced nutrient supply and lower crop yields. To quantify optimum dose for green gram (Vigna radiata L.), a series of field experiments were conducted at Regional Research Station, CCS HAU, Bawal, Haryana, to assess the response of green gram to fertilizer potassium on coarse textured (Typic Haplustepts) soils of southern Haryana. After completion of research trials, crop was tested on farmer's field through demonstrations and on farm trials (OFTs) to evaluate the response and adoptability of green gram as per the fertilizer potassium doses concluded in research experiment. Five levels of fertilizer potassium (0, 10, 20, 30 and 40 kg K2O ha-1) were evaluated for the response of green gram in randomized block design replicated thrice. The results of research trials revealed that the yield, protein content and growth parameters of green gram increased significantly with the application of fertilizer potassium @20 kg K2O ha-1. Significantly higher yield of green gram was recorded (5.87, 16.29, 19.23 and 22.36 %) due to application of 10, 20, 30 and 40 kg K2O ha-1, respectively over control. The total K uptake by green gram increased significantly with the incremental doses of potassium application which helped to prevent the depletion of available soil K and build-up its content in the soil. The mean K use efficiency varied from 38.30 to 54.15 and maximum (54.15 %) was recorded with the application of 20 kg K2O ha-1. The benefit cost ratio was also increased with the application of potassium and reflected in terms of additional returns per rupee (Rs. 10.94, 15.63, 12.17 and 10.72) invested on application of K @ 10, 20, 30 and 40 kg K2O ha-1, respectively. The farmer's field trial results with 0 and 20 kg K2O ha-1 revealed that application of 20 kg K2O ha-1 increased the yield of green gram by 10.87% over control. [ABSTRACT FROM AUTHOR]

A field experiment was conducted at Agronomy research farm, S.K.N. College of Agriculture, Jobner during kharif, 2015 in order to evaluate the performance of groundnut (Arachis hypogaea L.) under varying levels of sulphur and its sources. Results of experiment revealed that CGR of crop during 0 - 35 DAS registered significant increase upto application of sulphur at 45 kg/ha. However, at later stages of growth the significant increase was noted upto 60 kg S/ha only. Application of sulphur at 60 kg/ha recorded a significant increase of 6.1 per cent in RGR over 15 kg/ha during 70 DAS - at harvest stage. Likewise, application of 60 kg S/ha also significantly enhanced the number of total and effective nodules as well as fresh and dry weight of nodules/plant and produced significantly higher pod and biological yields of groundnut (1832 and 5361 kg/ha) than 45, 30 and 15 kg/ha. Application of sulphur through gypsum recorded significant increase in plant height and dry matter accumulation/m row length at all the stages of crop over SSP and elemental sulphur treatments. The maximum CGR at all the stages of crop was recorded when sulphur was applied through gypsum. Sulphur application through SSP registered 13.9, 9.8 and 21.4 per cent increase in CGR over elemental sulphur at these stages, respectively. On the other hand, SSP and gypsum increased the RGR by 7.2 and 6.3 per cent, respectively over elemental sulphur. Gypsum as a sources of sulphur fertilization recorded the highest number of 62.30 total and 55.00 effective nodules/plant and as well as fresh and dry weight of nodules (229.87 and 102.00 mg/plant) thereby increasing to the extent of 22.1, 27.6, 23.9 and 18.9 per cent over elemental sulphur. Sulphur application through gypsum produced 13.1 and 10.2 per cent higher pod and biological yield of groundnut over elemental sulphur. [ABSTRACT FROM AUTHOR]

The experiment was conducted at farmers field Near Regional Agriculture Reserach Centre Hazaratpur, Firozabad of Chandra Shekhar Azad University of Agriculture and Technology Kanpur during the consicutive Kharif season 2007-08 and 2008-09 to find the effect of inorganic chemical fertilizers with organic, source of nutrients on growth and yield of Okra variety Azad Bhindi-1. The results revealed that the integrated application of 75% RDF with varmicompost @ 6 t/ha gave significantly higher marketable fruit yield (99.80 q/ha), over control which was closely followed by the treatment namely 50% RDF + Vermicompost @ 6 t/ha (92.45 q/ha), 75% RDF + Neem cake @ 3.0 t/ha (80.30 q/ha). Integrated application of either 50% or 75% RDF with Vericompost @ 6t/ha or neem cake @ 3.0q/ha, resulted in significant improvement in vegetative and fruit characters in Okra over control. Thus for better vegetative growth, fruit attributes and marketable yield in okra, integrated use of inorganic and organic sources of nutrient supply was formal better than the other treatment application.

A field experiment was conducted at Bharari Jhansi (U.P.) of Chandra Shekher Azad University of Agriculture and Technology Kanpur, during consecutive Rabi season 2004-05 and 2005-06 to study the effect of time of sowing and specing on seed yield of pea CV. Azad P-3. First fort night of November (12 Nov.) was highest seed yield (18.7 q/ha) under 30 cm specing with thining distance between plant to plant 10 cm. [ABSTRACT FROM AUTHOR]

A field experiment was conducted at Bharari, (Jhansi) by Chandra Sekhar Azad University of Agriculture & Technology, Kanpur during to consecutive Rabi seiason 2005-06 and 2006-07. Results obtained from the data depicted in manuscript reveals that maximum yield of tomato and its growth & development characteristics along with yield components and quality attributes obtained in that plot which was treated with phosphorus as S.S.P. @ 450 kg/ha-1 + Phosphorus Solubilizing Bacteria + FYM@30 t ha-1. Combind application all three treatments was more beneficial than that of its alone application. Seed of tomato treated with PSB showed significant increasing effect on yield and yield attributing characteristics. Although, in genral, the integrated response of various treatments were significantly higher during second year than that of first year. [ABSTRACT FROM AUTHOR]

A field experiment conducted at Hazrapur, Firozabad during to Consicutive Kharif season, 2007 and 2008. Five varieties of onion were studied for their suitability in Kharif season for two years. Plant height and number of leaves/plant were significantly higher Arka Niketan. Maximum bulb diameter (5-60 cm) was noted in Arka Niketan variety. Which was at par with Agrifound dark red (5-37 cm) Maximum bulb yield (182-98 q/ha) was produced by Agrifound dark red, followed by Arka Niketan (168-45 q/ha), while minimum bulb yield (92.75 q/ha) was recorded in Agrifound light red. Toltal soluble solids was high (12-0 B) in Arka Niketan. Minimum total soluble solids (9.6 B), was recorded in N-53 varity. [ABSTRACT FROM AUTHOR]
