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.

Bermudagrass [Cynodon dactylon(L.) Pers. ♯ CYNDA ‘Vamont’, ‘Midiron’, andCynodon dactylonXCynodon transvaalensisBurlt-Davy ♯ CYNTR ‘Tifway’] cultivars were tolerant to oxadiazon [2-tert-butyl-4(2,4-dichloro-5-isopropoxyphenyl)-Δ2-1, 3,4-oxadiazolin-5-one] applied at rates up to 4.5 kg ai/ha during sprig establishment. The rate of shoot growth from sprigs after oxadiazon treatment was excellent and provided adequate ground cover within 3 months. Oxadiazon applications adversely affected root development of the Midiron cultivar as measured by the force required to uproot the sod. Root development of Vamont and Tifway after oxadiazon application was equal to that of untreated bermudagrass. Oxadiazon plus bensulide [O,O-diisopropyl phosphorodithioateS-ester withN-(2-mercaptoethyl)benzenesulfonamide] was inhibitory to both root and shoot growth of all cultivars. Metribuzin [4-amino-6-tert-butyl-3-(methylthio)-as-triazin-5(4H)-one] applications at 3 and 5 weeks after sprigging caused severe root injury to Vamont and Midiron bermudagrass.

The experiment was conducted to study the effect of salicylic acid (SA) as foliar spray on yield and yield contributing characters of BRRI Hybrid dhan3.The experiment was laid out in a randomized complete block design (RCBD) with three replications and six treatment combinations as, T1: 0 μM SA, T2: 200 μM SA, T3: 400 μM SA, T4: 600 μM SA, T5: 800 μM SA and T6: 1000 μM SA. The results revealed that biomass production, dry matter production and yield and yield contributing characters were significantly increased due to the foliar application of SA. At the maximum tillering (MT) stage, the highest biomass production (15.0 t/ha) and dry matter production was observed in T3 treatment. Treatments T4, T5 and T6 showed significant variation on the effective tillers/hill. The maximum effective tillers/hill were found in the treatment T6. The percentages of spikelet sterility were decreased with increasing the level of SA and the percentage of filled grains/panicle were increased with increasing level of SA. The insect infestation was reduced with increasing level of SA to up to 1000 μM. The maximum grain yield (9.21 t/ha) and straw yield (9.22 t/ha) was found in the treatment T6 which was identical to T5. On the other hand, in all cases the lowest results were found in the control treatment. The result showed that grain yield of rice increased with increasing level of SA to up to 1000 μM (T6 treatment). Our results suggest that foliar spray of SA might be applied to increase the yield of hybrid rice in Bangladesh.Res. Agric., Livest. Fish.4(3): 157-164, December 2017

Abstract Foliar nitrogen (N) application is considered an important factor affecting phenology, growth, yield, and yield components of dryland wheat (Triticum aestivum L.). A field experiment was conducted to study effects of foliar N on dryland wheat (cv. Prisabk-2004) at the Agronomy Research Farm, The University of Agriculture Peshawar, Pakistan, during winter 2010-2011. The experiment was laid out in randomized complete block design using four replications. A plot size of 3 m by 4 m, having 8 rows, 4 m long and 30 cm apart was used. A total of 80 kg N ha−1 in the form of urea was applied. Out of 80 kg N ha−1, 70 kg N ha−1 was applied to the soil at sowing time, and the remaining 10 kg N ha−1 was applied in the form of foliar spray (2% N). The required foliar N was applied in various combinations (splits) at different growth stages viz. 30, 60, 90 and 120 days after emergence (DAE). Phenological development (days to anthesis and physiological maturity) was delayed, yield components and yield increased significantly (p ≤ 0.05) with foliar N over control (water spray without N). Wheat grain yield increased to the highest level (4427 kg ha−1) when 100 % foliar N was applied (no split) at 90 DAE, followed by 4050 kg ha−1 at 120 DAE, while the control (no foliar N) resulted in the lowest grain yield (2573 kg ha−1). We concluded from this study that 2 % foliar N application in a single split either at 90 or 120 DAE could improve wheat productivity under dryland condition.

Enhancing the food production for the growing world population has needed application of highly sustainable and efficient inputs to produce more food per unit of land. Hence, Tamil Nadu Agricultural University (TNAU), Coimbatore, Tamil Nadu has produced Water soluble fertilizers (WSF) in its maiden attempt and it is necessary to optimize on different crops. Small onion is one of the most important vegetables in the Indian diet and it has high demand but low productivity. To enhance crop productivity and quality of small onions, the application of TNAU-WSF was taken up. A field experiment was laid out in a Randomized block design (RBD) incorporating 8 treatments comprising of application of RDF at100% NPK as TNAU WSF, soil test based application of 75%, 100%, 125% NPK ha-1 as TNAU-WSF with soil application of sulphur (S) and foliar spray of TNAU Liquid multi micronutrient (LMM) and without S and TNAU LMM and absolute control. Each treatment was replicated thrice with onion (CO 4). Soil test based application of 125% NPK ha-1 as TNAU-WSF with sulphur (S) and TNAU LMM recorded significantly higher in plant height (54.01 cm), the number of leaves per bulb (8.56), leaf greenness (67.5 SPAD), root length (5.42 cm), polar bulb diameter (4.38 cm), equatorial bulb diameter (2.72 cm) fresh bulb weight (74.21 g), bulb yield (1751 t ha-1) and quality attributes like total soluble solids (TSS) (14.78 °Brix), ascorbic acid content (15.34 mg 100 g-1), pyruvic acid content (2.27 µmol g-1). However, soil test based application of 100% NPK ha-1 as TNAU-WSF was found to be an ideal rate to attain the economic target yield of the onion crop.

Objective of this study was to examine and evaluate the role of different rates of salicylic acid (SA) as foliar spray on growth and yield performance of BRRI dhan29. The experiment was conducted at Sher-e-Bangla Agricultural University, Bangladesh from November, 2016 to May, 2017 following a randomized complete block design with five rates of SA in six replications. The results showed that the lower rate of SA (upto 0.75 mM) has a positive effect on rice biomass production including effective tiller per hill, filled grain per panicle, grain yield and straw yield. The highest dry matter production at both maximum tillering and panicle initiation stages was found at SA spray rate of 0.5 mM. The highest number of effective tillers per hill (14.7) as well as the highest filled grain (120.4) and grain yield (8.1 t/ha) were found at SA rate of 0.75 mM. However, the maximum biomass production was obtained at SA rate of 0.25 mM. The minimum grain yield (7.0 t/ha) was observed in the control treatment.

A field experiment was conducted during Kharif 2018 at College Farm, College of Agriculture, PJTSAU to evaluate the effect of various sources of zinc and iron on grain yield, nutrient uptake and grain quality parameters of finger millet. The experiment was laid out in a randomized block design with 14 treatments and replicated thrice.The results revealed that application of different Zinc and iron sources at different rates significantly influenced the grain yield, nutrient (N, P and K) uptake and grain quality parameters (protein and calcium content) of finger millet. Highest grain yield (3653 kg ha-1), protein (11.25%) and calcium content (2.33%) in grain were obtained in the treatment receiving RDF + foliar application of FeSO4 @ 0.5% twice at 30 and 60 DAS which was on par with treatment receiving RDF + foliar application of Fe-humate twice at 30 and 60 DAS (3612 kg ha-1, 10.90% and 2.0%) and the lowest grain yield (1995 kg ha-1), (6.25%) and calcium content (1.10%) were recorded with application of RDF alone. The nutrient uptake (N, P, K and Fe) at all the crop growth stages was significantly higher with the treatment receiving RDF (60:40:30 kg N,P2O5 and K2O kg ha-1) + foliar application of FeSO4 @ 0.5% twice at 30 and 60 DAS which was on par with treatment receiving RDF+ foliar application of Fe-humate twice at 30 and 60 DAS. Highest iron uptake was recorded in treatment receiving RDF+foliar application of FeSO4 @ 0.5% twice at 30 and 60 DAS which was on par with T8, T14 treatments.The highest nutrient uptake of Zinc was obtained in treatment receiving RDF + Zn Humate foliar spray @ 0.25% twice at 30 and 60 days after sowing which was on par with treatment receiving RDF + Zn Humate soil  application. Contrary to the grain yield, nutrient uptake, protein and calcium content there were no significant differences between treatments with respect to Zn, Fe and carbohydrate content in grain.

The experiment was conducted at the Agronomy Field Laboratory, Bangladesh Agricultural University, Mymensingh, to explore the growth and yield performance of boro rice cv. BRRI dhan28 is influenced by foliar spray of potassium nitrate (KNO3) at four rice growth stages. The experiment consisted of four doses of KNO3 viz. 0 (Control), 0.25, 0.50 and 1.00 kg ha−1 and applied at four growth stages of rice development viz. at panicle initiation, at ear emergence, at anthesis period and at dough stage. This experiment was carried out in Randomized Complete Block Design (RCBD) with three replications with 10 m2 (4.0 m × 2.5 m) unit plot size and spacing between blocks and unit plots was 1 m and 0.5 m, respectively. Results revealed that foliar application of potassium nitrate at four growth stages significantly affected yield and yield contributing characters of BRRI dhan28. But most of the yield contributing characters did not differ significantly due to the interaction between potassium nitrate and stage of foliar spray. However, the foliar application of KNO3 @ 0.25 kg ha−1 showed the highest yield production (5.86 kg ha−1) while the lowest yield (4.85 kg ha−1) was found in control. Furthermore, better yield performances were recorded when the KNO3 was applied at panicle initiation stage rather than the other four growth stages. The total number of tillers, 1000–grain weight and grain yield, was higher with foliar spraying of a 0.25 kg ha−1 KNO3 at panicle initiation stage. From this experiment, it may be concluded that foliar application of KNO3 affected the yield performances of BRRI dhan28 and 0.25 kg ha−1 KNO3 produced the highest grain yield when applied at panicle initiation stage of boro rice.

Background: The improvement in livestock productivity may be possible by availing better quality fodder in adequate quantity to the dairy farmers. Zinc deficiency might be a major factor for lower quality fodder of cowpea. Methods: The experiment was laid out in factorial randomized block design; comprised of three cowpea cultivars viz., C-152, MFC-08-14 and MFC-09-1 and five zinc management practices viz., control; 10 kg ZnSO4 as basal; 20 kg ZnSO4 as basal; 0.5% ZnSO4 as foliar spray at 20 DAS; 0.5% ZnSO4 as foliar spray at 20 and 40 DAS. Result: Results revealed that C-152 showed significantly better quality in terms of higher dry matter, crude protein and total ash; and lower acid insoluble ash, neutral detergent fibre, acid detergent fibre and acid detergent lignin amongst all the three varieties. Though, remarkably higher ether extract was obtained with MFC-08-14. Among the zinc management practices, 20 kg ZnSO4 as basal (Zn3) and foliar application of 0.5% ZnSO4 at 20 and 40 DAS (Zn5) recorded significant improvement in fodder yield and quality traits of cowpea.
