Background: Nitrogen and phosphorus are amongst fundamental macronutrients, which are crucial for the growth and development of plant. Soils of dry land of central Rajasthan are deficit in nitrogen and phosphorus content which leads to lower productivity of kasuri methi. Therefore, adequate supply of nitrogen (foliar spray) and phosphorus could enhance productivity of kasuri methi. Methods: The experiment consisted of sixteen treatment combinations including four levels of phosphorus (control, 20, 40 and 60 kg/ha) and four levels of foliar application of nitrogen (control, 1.0, 1.5 and 2.0%). They were under taken in FRBD with three replications. Result: Growth parameters and yield of fresh and dried leaves of the crop increased almost linearly with increasing levels of phosphorus and foliar application of nitrogen. The result indicated that application of phosphorus 60 kg/ha and foliar nitrogen @ 2.0% to the kasuri methi crop significantly increased the plant height (cm) and leaf area per plant (cm2) at each harvest, number of nodules per plant (58.17 and 53.33, respectively) and chlorophyll content (2.32 and 2.39 mg/100 g, respectively), fresh leaves yield (139.1 and 141.66 q/ha, respectively), dry leaves yield (20.01 and 22.38 q/ha, respectively), protein content in leaves (5.28 and 5.75%, respectively) and ascorbic acid in leaves (218.15 and 222.42 mg/100 g, respectively).

A field experiment was conducted at the Plant Physiology Field of Horticulture Research Center (HRC), Bangladesh Agricultural Research Institute, Gazipur during the rabi seasons of 2015-16 and 2016-17 to study the response of cabbage (var. Krishibid Hybrid-1 and Atlas-70) to foliar application of GA3 and NAA with different concentrations. The experiment was laid out in a Randomized Complete block Design with three replications. The experiment consisted of eight treatments viz., three levels of GA3 (at 50, 75 and 100 ppm) and four levels of NAA (at 40, 60, 80 and 100 ppm) along with distilled water as control. The varieties Krishibid Hybrid-1 and Atlas-70 were used in 2015-16 and 2016-17, respectively. Foliar spray of GA3 and NAA was given at 25 and 45 days after transplanting of seedling. The results of the investigation indicated significant differences among the treatments on most of the parameters studied. In Krishibid Hybrid-1, application of 50 ppm GA3 and 60 ppm NAA increased plant height, plant spread, number of leaves, chlorophyll content, head height, head diameter, single head weight without unfolded leaves as well as head yield (81.18 t/ha for 50 ppm GA3 and 78.57 t/ha for 60 ppm NAA) than the control (67.29 t/ha) and other treatments. But, in Atlas-70, application of 75 ppm GA3 gave the maximum values of most of the growth parameters, yield components and yield (102.40 t/ha), which was followed by 50 ppm GA3 (94.96 t/ha). In Krishibid Hybrid-1, application of 60 ppm NAA gave the highest benefit-cost ratio (BCR) of 3.63 followed by 75 ppm GA3 (3.59) while in Atlas-70, 75 ppm GA3 recorded the highest BCR of 4.79 followed by 50 ppm GA3 (4.54) and 60 ppm NAA (4.37). Therefore, application of GA3 @ 50-75 ppm or NAA @ 60 ppm concentration can be recommended for increasing the yield of cabbage with higher return. Bangladesh J. Agril.

Turf grasses have been utilized by humans to enhance their environment for more than 10centuries. Aesthetically, lawns enhance the quality of life, contribute to social harmony andcommunity pride, increase property values and compliment other landscape plants. The beautyof any garden largely depends on the greenness of the lawn. The first and foremost criteria fora well establishment and a satisfactory lawn are selection of suitable grass species and methodsof its establishment. Hence, an experiment was laid out to study the effect of different spriggingdensity and foliar nitrogen on the growth and establishment of bermuda grass (Cynodon dactylonL. Pers. x Cynodon transvaalensis) in floriculture unit of the Department of Horticulture, Facultyof Agriculture, Annamalai University, Tamil Nadu during the year 2013-2015. Bermuda grasssprigs were planted in different spacing levels and foliar spray of urea with twelve treatmentcombinations comprising of different levels viz., 10 x 10 cm with 1%, 1.5% and 2%; 15 x 15 cmwith 1%, 1.5% and 2%; 20 x 20 cm with 1%, 1.5% and 2%; 25 x 25 cm with 1%, 1.5% and2%, in factorial randomized block design with three replications. From the results, it wasfound that the earliest spread and ground cover were observed in planting sprigs at closerspacing of 10 x 10 cm in combination with foliar application of nitrogen in the form of urea as2 % for two times at seven and fifteen days after planting.

Nitrogen and micronutrients have a key role in many citrus plant enzyme reactions. Although enough micronutrients may be present in the soil, deficiency can develop due to soil depletion or the formation of insoluble compounds. The objectives of this study were to (1) determine the adsorption, distribution, and availability of Zn in a sandy soil; (2) compare the effectiveness of foliar and soil application methods of Zn on Huanglongbing [HLB] affected trees; (3) compare foliar application rates of Zn for HLB-affected trees; (4) determine the effect of N rates on yield, soil inorganic N distribution patterns, and tree growth parameters. Tree rows were supplied with three N rates of 168, 224 and 280 kg·N·ha−1 and Zn at single and double recommended rates (recommended rate = 5.6 kg·Zn·ha−1) using foliar and soil application methods, in a split-plot experimental design. The results show that Zn concentration in the 0–15 cm soil depth was three times higher than the 30–45 and 45–60 cm soil depths during the study. An adsorption study revealed high Zn (KD = 6.5) sorption coefficients at 0–15 cm soil depth, while 30–45 and 45–60 cm depths showed little sorption. Leaf Zn concentration for foliar spray was two times higher than the soil application method. A nitrogen level of 224 kg N ha−1 improved canopy volume when compared to other N levels at the expense of reduced fruit weight. Foliar Zn application at 5.6 or 11.2 kg ha−1 and N rate at 224 kg ha−1 appear to be adequate for improving the performance of HLB-affected citrus trees.

A greenhouse experiment was conducted during rabi season of 2015-16. The experiment was laid out in complete randomized design with four levels of phosphorus (0, 11, 22 and 33 mg P2O5 kg-1 soil) and three levels of bio-inoculants (uninoculed, Rhizobium and Rhizobium + PSB) and three replications. Results revealed that application of 22 mg P2O5 kg-1 significantly increased the plant height, number of branches plant-1, number of leaves plant-1, pods size and number of grains pod-1 and it was at par with 33 mg P2O5 kg-1. However, 33 mg P2O5 kg-1 showed significant increase over the lower phosphorus levels with respect to number of pods plant-1, grain and stover yields. Dual inoculation with Rhizobium + PSB significantly increased plant height, number of branches and leaves plant-1, number of pods plant-1 and pods size over control, while Rhizobium alone was at par with control on these parameters. Rhizobium significantly increased the grain and stover yields over control while Rhizobium + PSB had significant effect over control as well as Rhizobium alone. Interaction effects revealed that highest grain and stover yields were obtained with 33 mg P2O5 kg-1 without inoculation and inoculation with Rhizobium, but yield was at par with 22 mg P2O5 kg-1 when crop inoculated with dual inoculants (Rhizobium + PSB). Application of 33 mg P2O5 kg-1 resulted in the highest content of nitrogen and phosphorus in grain and stover whereas 22 mg P2O5 kg-1 gave highest content of potassium. Rhizobium had significant effect only on nitrogen content whereas Rhizobium + PSB increased both nitrogen and phosphorus contents. Uptake of nutrients by the crop increased significantly with application of P and bio-inoculants. Phosphorus and bio-inoculant application improved only phosphorus content significantly of post harvest soil.

Among the various technologies that boost the production of crop, nutrient management has got an important impact in maximizing the yield. Application of balanced fertilizers alone is not only the solution for this problem, application of residue free nutrients that protects the soil health and environment is very important. Here comes the concept of organic farming. Hence, a field experiment was conducted in the Department of Horticulture, Faculty of Agriculture, Annamalai University, Annamalai Nagar to study the effect of organic nutrients on growth and physiological parameters of radish. The experiment was conducted with eighteen treatments in three replications and laid out in FRBD design. The treatment includes various sources of organic manures viz., FYM, vermicompost, enriched manure along with and without use of consortium biofertilizer. Biostimulants viz., buttermilk solution and EMI were given as foliar spray at 15 days interval as 2 sprays. The intercultural operations and plant protection measures were carried out as per the recommendation. The results of the experiment revealed that application of farm yard manure @ 25 t ha-1 along with consortium biofertilizer @ 2 Kg ha-1 and EMI @ 1:1000 dilution ha-1 as foliar application recorded the highest growth parameters viz., shoot length, number of leaves and shoot weight. The physiological parameters viz., leaf area and chlorophyll content were recorded the highest in the same treatment T6.
