A field experiment was conducted to study the effect of different levels of potassium and zinc on growth, yield and economics of sweet potato. The experiment was laid out on clay and loam soil by adopting randomized block design with factorial technique (FRBD). The sixteen treatments consisted of combination of four levels of po-tassium (0, 80, 100 and 120 kg/ha through muriate of potash and four levels of foliar zinc (control i.e. water spray, 10, 20 and 30ppm) through zinc sulphate. The individual application of potassium 120 kg K2O/ha significantly in-creased the number of tubers per plant (4.60), average weight of tuber (275.31 g), length of tuber (16.77 cm), diam-eter of tuber (5.69 cm), tuber yield per plot (9.71 kg), tuber yield per hectare (49.04 t) respectively as compared to control. With the foliar application of zinc (30 ppm) significant increase in number of tubers per plant (4.18), average weight of tuber (234.73 g), length of tuber (18.12 cm), diameter of tuber (5.16 cm), tuber yield per plot (8.33 kg) and tuber yield per hectare (42.05 t) was recordedas compared to control. The treatment combination (120 kg K2O+30ppm Zn) recorded the maximum yield parameters i.e. chlorophyll content (37.00 mg/100 g), average weight of tuber (302.17 g), length of tuber (19.82 cm), diameter of tuber (5.97 cm), maximum tuber yield per plot (11.02 kg), tuber yield per hectare (55.67 t) and benefit-cost ratio (B: C ratio) of 4.22:1.While, the treatment (120 kg K2O+30ppm Zn) had the maximum number of tuber (4.86), minimum number of tuber was recorded in control. From the experi-ment, it appeared that application of potassium and zinc can be used to improve yield and higher net monetary re-turns of sweet potato.

The Impact

The impact of temperature and potassium fertilizers on the growth, yield, and basic biochemical characteristics of sweet potato, <em>Ipomoea batatas </em>var. Antin- 1, was investigated in lowland and highland terrains. In this study we aimed to determine the different traits of the sweet potato, based on its morphology, physiology, and biochemical composition, following treatments with a potassium fertilizer at different temperatures. The study was undertaken using a nested factorial design. The first factor was temperature at each of the two sites: T1 (lowland) and T2 (highland). The second factor was potassium fertilizer (K<sub>2</sub>O) nested within the temperature factor and consisting of four levels of K: K0 (0 kg/ha), K1 (50 kg/ha), K2 (100 kg/ha), and K3 (150 kg/ha). Each potassium treatment was replicated three times at each location. Plant vegetative growth in the lowland region, with a daily average temperature of 26.8 °C, tended to be more bushy, with several different morphological properties: The main stem was longer (160.7 cm) and spreading, the stem diameter was greater, and the petioles were significantly longer in the lowland plants compared with the highland plants; however, no differences were observed in the leaf characteristics. The differential temperature (depending on altitude) resulted in significant differences in relative growth rates (RGR) and net assimilation rates (NAR); the values for RGR-1 and NAR-1 in the lowlands were higher than those in the highlands. The tuber weight, yield index, anthocyanin accumulation, and glucose content were significantly higher in the highland crops than in the lowland plants, which grew under relatively higher temperatures. Potassium applications caused significant differences in the anthocyanin content (mg/100 g fresh weight), anthocyanin production (kg/ha), and glucose production (kg/ha) at different locations.

Durum wheat has a comparative adaptive advantage over bread wheat under hot and dry conditions. Accordingly, it feeds millions of people in the Middle East and North Africa. Under these conditions, the deficiency of nutrients, including micronutrients, is a major concern for many reasons, including calcareous soil under drought stress conditions. Therefore, growth, yield, iron (Fe) and zinc (Zn) concentration in durum wheat cultivar grains were investigated. A factorial experiment based on a randomized complete block design with three replications was conducted in the Dryland Agricultural Research Institute (DARI) - Moghan. The first factor comprised spraying at four levels, including the control and foliar spraying with Fe, Zn, and Fe+Zn and the second factor consisted of genotypes at four levels: Dehdasht (G1), Seymareh (G2), and two new genotypes (G3 and G4). Solutions of Fe and Zn fertilizers were sprayed at the tillering, early ear emergence, and milk stages, with a ratio of 2 and 1.5 g fertilizer/1000 ml solution (W/V), respectively. The results showed that genotypes G1, G3 and G4 produced higher grain yield per square meter than G2. This increase was due to the higher weight of 1000 grains in G3 and G4 genotypes and 1000-grain weight with a higher grain number in G1. G1 and G2 had greater spike length, number of grains per spike and spikelet than G3 and G4 genotypes. In all studied traits, except Fe and Zn concentration, the combination of Fe+Zn showed the highest and control had the lowest performance. Also, the application of Zn was superior to Fe. The highest Fe concentration of G1, G2, G3, and G4 was observed at Fe+Zn, control, Zn, and Fe levels, respectively. The highest Zn concentrations were observed in the G3 genotype when only Zn was used or in combination with Fe. According to the results, the Fe and Zn spray application increased durum wheat yield on Fe and Zn deficient soil.

A field experiment was conducted to find out the response of foliar application of micronutrients on growth, yield and economics of tomato (Lycopersicon esculentum Mill.) at collage orchard, Department of Vegetable Crops, HC & RI, Tamil Nadu Agricultural University, Coimbatore. The treatments consisted of boric acid @100 ppm, ZnSo4 @ 100 ppm, ammonium molybdate @ 50 ppm, copper sulphate @ 100 ppm, ferrous sulphate @ 100 ppm, manganese sulphate @ 100 ppm, mixture of all, mixture of all without B, mixture of all without Zn, mixture of all without Mo, mixture of all without Cu, mixture of all without Fe, mixture of all without Mn, commercial formulation (Multiplex) @ 4 ml/lit and control (without spray). The experiment was laid out in a randomized block design with three replications. All the micronutrients were sprayed individually and in combinations on tomato in three sprays at an interval of 10 days starting from 40 days after transplanting. The results revealed that spraying of mixture of all micronutrients (T7 ) 3 times at an interval of 10 days starting from 40 days after transplanting resulted in the highest plant height (95.7 cm), number of fruits per plant (46.4), fruit weight (61.9 g), fruit yield per plot (63.5 kg), yield/ha (564.1 q) and benefit cost ratio (3.04) followed by the spray of commercial formulation (Multiplex).

An experiment was conducted at the Horticulture Farm, Sher-e-Bangla Agricultural University, Dhaka, from October 2017 to February 2018. The experiment consisted of two factors, Factor A: Four levels of organic manures, viz. M0 = Control; M1 = Cowdung (35 t ha-1), M2 = Mustard oil cake (3.5 t ha-1) and M3 = Vermicompost. Factor B: Three application times, viz. T1 = 15 days before transplanting, T2 = Application at the time of transplanting and T3 = 15 days after transplanting. The experiment was laid out in a randomized complete block design (RCBD) with three replications. In the case of organic manure, the highest yield (38.70 t/ha) was found from M2 treatment, whereas the lowest yield (19.71t/ha) was recorded from M0 treatment. In the case of application time, the highest yield (31.83t/ha) was found from T1 treatment, whereas the lowest yield (28.10 t/ha) was recorded from T3   treatment. Due to combined effect maximum yield (38.704 t/ha) with net return (4,74,421tk) and BCR (2.20) was obtained from M2T1 treatment combination while the lowest yield (17.90 t/ha) with the lowest income (44,211 tk) and BCR (1.17) from M0T3 treatment combination. So, the economic analysis revealed that the M2T1 treatment combination appeared to be best for achieving the higher growth, yield and economic benefit of cauliflower.

Growing Conditions

Brinjal is a crop grown widely all over India and preferred by both rich and poor. The Chhotanagpur plateau of Jharkhand is famous for quality vegetable production and brinjal is very commonly grown in this region almost throughout the year. However, the most of the commercial growers using plant protection chemicals and synthetic fertilizers those are so expensive that poor farmers can’t afford. The extensive uses of agro-chemicals and synthetic fertilizers also reduce the quality of both the produce and the cultivated soil. In this context, an attempt has been made through the present investigation by growing different varieties of brinjal by adopting Vedic (Enriched Sanjeevani) Farming and Homa Induction (Agnihotra) techniques with their respective four non-chemical alternative growing approaches, viz.  E1C1: Enriched Sanjeevani (1%), E1C2: Absolute Control (inherent fertility status of the experimental plot); E2C1: Enriched Sanjeevani (1%) + Homa Induction (Agnihotra), and E2C2: Only Homa Induction (Agnihotra). Five varieties of the crop, viz. V1: Swarna Pratibha; V2: Swarna Neelima; V3: Swarna Shakti; V4: Mukta Jhuri; V5: Long Green were grown with their four replications under four growing conditions and the Randomized Completed Block Design was adopted for field trials. Different growth, yield and quality attributing characters of the crop were taken into account and findings revealed that E2C1: Enriched Sanjeevani (1%) + Homa Induction (Agnihotra) was the most suitable growing condition for V2 (Swarna Neelima) with the maximum yield (72.37 t ha-1). Different growth and yield attributes of the crop varieties (especially in the case of V2: Swarna Neelima) were highly influenced by Enriched Sanjeevani (1%) + Homa Induction (Agnihotra) [E2C1] growing condition resulting higher benefit cost ratio of 6.78. Quality contributing attributes were also highly influenced by homa induction (Agnihotra), as a consequence, higher level of dry matter, TSS, and ascorbic acid contents were estimated from almost all samples collected from E2C1: Enriched Sanjeevani (1%) + Homa Induction (Agnihotra), and E2C2: Only Homa Induction (Agnihotra) growing conditions.

A field experiment was carried out during kharif season of 2016 and 2017 at an experimental farm of MACS Agharkar Research Institute, Pune, India to study the influence of foliar application of nutrient on growth, yield, economics, soil nutritional status and nutrient uptake of soybean crop. An experiment was laid out in randomized block design (RBD) comprising of three replications and nine treatments. Recommended dose of fertilizers (RDF) was applied as basal application to all treatments. Seven treatments consisted of different doses of nutrients as foliar application at pod initiation stage. Water spray at pod initiation stage and RDF alone were treated as control. The results revealed that, growth attributes, nodulation and its weight, morpho-physiological parameters, yield and its attributes, nutritional parameters and economics significantly differed by various foliar nutrition treatments except control and RDF + water spray. RDF + Urea 2% (3098 kg ha-1) gave significantly higher seed yield over control (2704 kg ha-1) and RDF + water spray (2686 kg ha-1) but was at par with RDF + DAP 2% (3050 kg ha-1), RDF + MOP 0.5% (2992 kg ha-1) and RDF + Molybdenum 0.5% (2955 kg ha-1). The increase in seed yield with foliar application of 2% Urea along with RDF was 14.57% over control and 15.34% over RDF + water spray. Higher net returns (Rs. 49,006/- ha-1) and benefit: cost ratio (2.23:1) was obtained in treatment RDF + Urea 2% followed by RDF + DAP 2% foliar spray. Availability of N, P and K was significantly higher with treatment RDF + Urea 2% foliar spray over control and RDF + water spray. N and P uptake by soybean plants was significantly higher in treatment RDF + 2% Urea over RDF + water spray and RDF alone (control).

Nitrogen, phosphorus, and potasium availability are the most thresholding factors for maximum growth and yield. The tuber yield of sweet potato varies depending on growing area therefore a fertilization program, especially in the type and the dose of the fertilizers, is required. This research was conducted in the Pasir Muncang experimental farm at Gadog, Bogor, West Java, Indonesia. The study site is located ±500 meters above sea levels, 6°39’31.90” south latitude and 106°52’7.77” east longitude. The experiment was started in May to September 2017. Multi nutrient response method was used for this study, and the interpretation of the results was used to develop fertilizer recommendations using single-nutrient quadratic model. The recommendation was determined using N, P2O5, K2O fertilizer response curve, where the first recommendation was calculated from the maximum relative yield,and the second, third, and fourth recommendation were determined from N, P2O5, K2O threshold. Each treatment for N, P and K was evaluated with different level of fertilizer dose using a randomized complete block design with three replications. The fertilizer doses were 50, 100, 150 and 200% from reference (100% N = 100 kg N ha-1, 100% P = 75 kg P2O5 ha-1, dan 100% K = 100 kg K2O ha-1). Relative yield of sweet potato (y), response to fertilizer (x) had improvement quadratically with equation y = -0.0017x2 + 0.538x + 40.035 for N, y = -0.0041x2 + 0.8595x + 38.211 for P2O5, and y = -0.0025x2 + 0.4318x + 73.377 for K2O. The optimized dose of fertilizer to get maximum yield of sweet potato tuber is 158.23 kg ha-1 of N, 78.60 kg ha-1 of P2O5, and 83.60 kg ha-1 K2O, or 343.97 kg ha-1 of Urea,  218.53 kg ha-1 of SP36 139.33 kg ha-1 of KCl.Keywords: multi nutrient response, nitrogen, relative yield, phosphorus, potassium

A field experiment was conducted at Rivers Institute of Agricultural Research and Training (RIART), Rivers State University, Port Harcourt, Nigeria with the objective of evaluating the influence of seedbed types and vine harvesting time on shoot and tuber yields of sweet potato and make recommendations for optimal and sustainable production. The treatments consisted of three seedbed types (ridge, flat, and mound), and four vine harvesting time (8, 12, 16 and 20 weeks after planting). The experiment was laid out as a 3 x 4 in factorial arrangement fitted into a randomized complete block design (RCBD) and replicated three times. The results revealed that planting of sweet potato on ridge produced the highest root tuber yield followed by mound seedbeds; planting on flat seedbed produced the highest shoot (vine) and lowest tuber yields. While planting on ridge seedbed and harvesting the vines 16 weeks after planting (when about 80% of the growth phase of the plant was completed) produced optimum shoot yield which could be used as fodder with no significant effect on root tuber yield. In general, vine harvesting during active growth phase of the sweet potato plant seriously depressed tuber yield more than it affected shoot production. These results therefore stand as our recommendations for sweet potato production in the South-south zone of Nigeria.

A field experiment was conducted at the Agronomy Field Laboratory, Bangladesh Agricultural University, Mymensingh from July 2016 to December 2016 to find out the effect of seedlings age and different nitrogen (N) levels on the yield performance of transplant Aman rice (cv. Binadhan-15). The experiment comprised four ages of seedlings  viz., 15 , 20 , 25, 30 day old and four levels of nitrogen viz., 0 ,55 , 75 and 95 kg N ha–1 following randomized complete block design (RCBD) with three replications. The effect of age of seedling, nitrogen levels and their interactions were significant on growth, yield and yield contributing characters of transplant Aman rice. The highest plant height at harvest (92.67 cm), number of effective tillers plant–1 (8.70), grain (4.55 t ha–1) and straw yields (5.49 t ha–1) were obtained from 75 kg N ha–1. By using optimum seedling age at 15 DAT the highest plant height (102.7cm at harvest), number of effective tillers plant–1 (8.29), grain (4.01 t ha–1) and straw (5.06 t ha–1) yields. In interaction, 75 kg N and 15 days old seedling produced highest plant height (106.3 cm at harvest), number of effective tillers plant–1 (9.42), grain (5.0 t ha–1) and straw yields (6.10 t ha–1). From the above results of the present study, it may be stated that Binadhan-15 is grown successfully for obtaining maximum yield with 75 kg N ha-1 and 15-day old seedling age individually or in combination.
