Aims: To compare the effects of basalt dust, Tithonia diversifolia (T. diversifolia) powder and NPK 20-10-10 on the growth and production of Garlic (Allium sativum, softneck variety) in Bafut (Cameroon Volcanic Line). Study Design: A randomized complete block design (RCBD) with three replications in the field was used. The treatments were T0 (control), T1 (0.7 tons ha-1 NPK 20-10-10), T2 (0.4 tons ha-1 basalt), T3 (0.6 tons ha-1 basalt) and T4 (0.5 tons ha-1 T. diversifolia powder). Place and Duration of Study: The study conducted in Bafut (Cameroon) from 2nd August 2017 to 24th February 2018. Methodology: Fieldwork involved land preparation, planting and collection of growth and yield parameters as well as rocks and soil sampling. Laboratory work involved soil physicochemical analysis and cutting of rock thin sections for microscopic observations. The plant data were subjected to statistical and economic analyses. Results: The control soil (T0) showed a sandy clayey loamy texture, acidic pH (5.1), very high organic carbon (6.4%), low total nitrogen (0.2%) and moderate available phosphorus (19.42 mg                kg-1). The exchangeable complex revealed high K+ (0.88 cmol (+).kg-1), very low Ca2+ (0.63 cmol (+).kg-1) and Mg2+ (0.21 cmol (+).kg-1), low Na+ (0.07 cmol (+). kg-1), very low sum of exchangeable bases (1.79 cmol (+).kg-1), moderate cation exchange capacity (CEC) (22.7 cmol (+). kg-1) and a very low base saturation (7.88%). C/N ratio was very high (35>17) indicating very poor quality organic matter and a potentially very slow mineralization rate. Growth and yield parameters, except fruit number, were such that T2>T3>T4>T1>T0. T2, T3 and T4 plants gave high yields while T1 recorded the lowest yields below the control. The net yield showed that T3>T4>T2>T0>T1 suggesting that basalt dust and T. diversifolia powder improved soil fertility that in turn boosted yields. Economically, T1 had a BCR (benefit-to-cost ratio)<1 indicative of no profit, while T2, T3 and T4 showed a BCR>2 indicating more than 100% profit of the investment and a possibility of popularization of these treatments. Conclusion: Natural basalt dust and T. diversifolia powder treatments gave better garlic yields indicating a better soil fertilizing capacity compared to synthetic NPK 20-10-10. Basalt dust and T. diversifolia can be popularized to local inhabitants.

Soil acidity is a major factor limiting green beans (Phaseolus vulgaris L.) production in the Cameroon western Highland. A field experiment (split-plot layout) was conducted with seven dolomite treatments (tons ha-1): control or T0 (0), T1 (0.5), T2 (1), T3 (1.5), T4 (2), T5 (2.5) and T6 (3). Soil physico-chemical properties were determined meanwhile growth and yield parameters were collected weekly for a month and analyzed statistically. Results revealed that control soils were texturally silty sandy. The exchangeable bases (except Na), cation exchange capacity (CEC), base saturation and available phosphorus were very high. They acidity was moderate to high (5.2 to 5.6) while organic matter was very high (% dry mass) and of moderate to good quality (11<C/N ratio<13). Crop variety showed a highly significant difference (P<0.001) for all growth and yield parameters, with Cogito producing the longest (13.88 cm), most numerous (40.94 pods per plant) and highest (16.96 tons ha-1) extrafine pods. Dolomite doses revealed no significant effects (P>0.05) on crop parameters, although highest yield (13.61 tons ha-1) of extrafine pods came from 2 tons ha-1. The dolomite dose versus variety interaction showed no significant difference (P>0.05). Farmers ought to improve soils with compost and cover crops to check nutrient leaching and erosion.

The research was conducted at Beltari Sandhikharka-10, Arghakhanchi district to study about the effect of various doses of boron on growth and yield attributing characters of cauliflower (Brassica oleracea var. botrytis) during off-season from February to June in 2020. Five treatments; B0 (control/no application), B1: 2kg/ha, B2: 4kg/ha, B3: 6kg/ha, B4: 8kg/ha which are the different doses of boron application were laid out in Randomized Complete Block Design (RCBD) with 4 replications. The growth parameters like plant height, number of leaves per plant leaf length and leaf breadth of largest leaf were recorded multiple times with 15 days interval. Days to curd initiation and Days from curd initiation to harvest were recorded by regular field observation. The yield parameters; curd weight with leaves, Marketable curd weight, average curd yield, incidence of hollowing were recorded during harvest. The economics from application of boron doses in cauliflower production was obtained in terms of cost of cultivation, gross returns, net returns, and benefit cost ratio. The result showed that the growth and yield attributing characters of cauliflower were significantly affected by application of boron in which the value of these parameters was found significantly higher in B1 followed by other treatments. The average curd yield of cauliflower in B1 was found to be 12.39 mt/ha which was 48.92% higher than that of B0 with curd yield 8.32 mt/ha. Similarly, the net return was found significantly the highest in B1 and the lowest in B0. The result showed that application of boron in the range of 2-4 kg/ha is preferred to control and higher doses in respect of both productivity and economics.

Vegetables are the prime source of vitamins and minerals. As the population increases there is also increase in demand for nutritional vegetables, but in the conventional method of horticulture the production and productivity is considerably less. Thus to increase the productivity and to feed the over burgeoning population there is a need for novel fertilizers such as Nano fertilizers. An experiment was hence conducted in Chinapettai village, Panruti to investigate the Bio-efficacy of Nano nutrients (Nano Nitrogen, Zinc and Copper) on growth and yield of Capsicum. The experiment was carried out in RBD design (Randomized block design) with three replications and ten treatments. Results showed that the treatment with 100% RD-N+100% RD-P + 100 % RD-K + Nano N + Nano Cu + Nano Zn followed by 100% RD-N +100% RD-P + 100 % RD-K + Nano N and 75% RD-N+100% RD-P + 100 % RD-K + Nano N + Nano Cu + Nano Zn recorded maximum growth and yield parameters. In contrast 50% RD-N + 100% RDP + 100 % RD-K + Nano N showed increase in yield than the control (100% RDF (-N: -P: -K)(250:150:150kg/ha)) to conclude that Nano nitrogen could have compensated the 50% urea recommendation in conventional fertilizer and also had enhanced effect than control.

AbstractA field experiment was carried out to investigate the effect of different manures and fertilizers on the growth and yield of knol-khol (Brassica oleracea var. gongylodes) at Dr. Purnendu Gain Field Laboratory of Agrotechnology Discipline, Khulna University, Khulna from November 2014 to February 2015. The single factor experiment comprised of different types of fertilizers and manures viz., T0 (Control), T1 (Recommended doses of NPK), T2 (Cow dung), T3 (Vermicompost), T4 (Poultry manure), T5 (50 % Cow dung + 50 % NPK), T6 (50% Vermicompost + 50% Cow dung), T7 (50% Vermicompost + 50 % Poultry manure) and T8 (25% Cow dung+ 25% Vermicompost+ 25% Poultry manure + 25% NPK). The Experiment was laid out in Randomized Complete Block Design (RCBD) with four replications. The maximum plant height was obtained from the treatment T1 at 25, 35 and 45 Days after transplanting (DAT). The maximum spread of canopy was 36.75 cm, 52.50 cm and 66.05 cm from the treatment T3, T7 and T2, respectively. The maximum economic yield (21.92 t/ha) and biological yield (40.083 t/ha) were found in the treatment T1 and T7, respectively. Highest benefit cost ratio (3.07) was obtained from the treatment T1whilethe minimum (0.57) was obtained from T3 which indicates that high cost of vermicompost affect net return severely. Although, T1 produced maximum benefit cost ratio, the treatment T4 and T2 are very close to T1 and also statistically similar. So, we can consider poultry manure and cow dung for our soil health, environmental benefits and ecological safety.

Research on the effect of dosage combination of Evagrow bio-fertilizer and chemical fertilizers on soil properties, growth and yield of rice has been carried out in the glasshouse, Faculty of Agriculture, Udayana University using factorial experiment with a Randomized Block Design (RBD). The first factor is Evagrow bio-fertilizer in 3 level, i.e. E0 (without bio-fertilizers), E1 (5 g bio-fertilizer/L) E2 (10 grams bio-fertilizer/L). The second factor is chemical fertilizer, which consists of 3 levels: K0 (without chemical fertilizers), K1 (150 kg Urea/ha + 75 kg SP36/ha + 37.5 kg KCl/ha), K2 (300 kg Urea/ha + 150 kg SP36/ha + 75 kg KCl/ha). The results showed that chemical fertilizers give a significant and very significant effect on most of the rice growth and yield parameters. The application of chemical fertilizers K1 and K2 increased yield of dry grain harvest to 52.87% and 102.54% compared to controls.  Application of Evagrow bio-fertilizer did not significantly increase growth and yield of rice. There is no interaction between chemical fertilizers and Evagrow bio- fertilizer.  Similarly to some of the soil characteristics, biological fertilizer and chemical fertilizer application did not show significant effect on most of the soil characteristics, except on salt levels.Keywords: Evagrow Biofertilizer, Inorganic Fertilizer, Oryza Sativa

Banana (Musa spp.) is a vigorously growing, monocotyledonous herbaceous plant. Though Bangladesh is more suitable for production of banana but its productivity is very low due to a lack of improve variety, sustainable production & protection technology, soil fertility and fertilizer management. Fertilizers i.e. nitrogen and potassium are one of the most important elements that can play vital role to increase productivity of banana. Hence, the present research investigation was conducted at the Horticulture Farm of Bangladesh Agricultural University, Mymensingh during the period from November, 2016 to December, 2017 to evaluate the effect of nitrogen & potassium fertilizers on growth and yield and also find out the best combination of N & K fertilizers for economic production of banana. Four levels of Nitrogen (N1=300g Urea/plant, N2=400g Urea/plant, N3=500g Urea/plant and N4=600g Urea/plant) and four potassium (K1=250g MOP/plant, K2=350g MOP/plant, K3=450g MOP/plant, K4=550g MOP/plant) were studied in a randomized complete block design (RCBD) with three replications. The results revealed that the single application of N3=500g Urea/plant, K3=450g MOP/plant and their combination (N3×K3=500g urea/plant×450g MOP/plant) showed more significant increase in morpho-physiological characteristics namely pseudo-stem height (m), pseudo-stem girth (cm), number of functional leaves, total number of leaves per plant, minimum days to bunch maturity & crop duration (days) and increase in yield contributing characters viz. total number of fingers per bunch, total number of hands per bunch, bunch weight (kg/plant), yield (t/ha) and benefit cost ratio in this study. The application of these two fertilizers as single or their interaction would be the most appropriate level for getting the superior growth and yield performance of banana.

Field experimental trials were carried out at Federal College of Forestry Mechanization, Afaka. Kaduna located between latitude 100 35”N and longitude 07°21”E at altitude 644m above sea level to compare the effect of different application of organic manures on growth and yield of water melon (Citrullus Ianatus). Two trials were conducted between the early onset of rain in April and post monsoon in October 2011 and the mean of the two trials were taken. The treatments were poultry manure, mixture of poultry manure plus goat/ sheep manure, goat/ sheep manure and control(no manure). The treatments were replicated four times in randomized complete block design. Data were collected on growth parameters such as plant vines length, Number of branches per plant, number of leaves and yield parameters like fruits weight, fruits diameter and number of fruits. The data were subjected to analysis of variance and the mean separated using Least Significant Difference. The results showed that there were significant differences (P<0.05) in plant vine length. The plots treated with poultry droppings had the highest value of plant vine length of 8.20, 137.90 and 216.30 cm at 2, 4 and 6 weeks after planting. Poultry droppings also gave the highest values for the weight of fruit (10.72 Kg) and diameter of fruit (53.25 mm). The best treatment is poultry manure which has the highest yield of 34.25% at 2.5 tonnes per hectare. Poultry manure showed positive effect on all the growth and yield parameters of water melon (Citrullus lanatus) measured. The use of poultry manure is therefore recommended for farmers in the study area in order to be able to obtain good yield of water melon.

A field experiment was conducted during rabi season of 2019 at farmer’s field in Panruti near Cuddalore district (Tamil Nadu) to study effect of organic manures as INM component on growth, yield and quality of chilli (Capsicum annuum L.) in a randomized block design. The treatments consisted of recommended dose of fertilizers at two levels (160:60:30 and 120:45:22.5 kg NPK ha-1) and organic manures (20 t FYM ha-1, 50 kg Bio ash ha-1, 5 t press mud granules ha-1, 20 kg Sea weed extract granules ha-1 and 5 t neem cake ha-1) and replicated three times. The growth and yield parameters of chilli were significantly influenced due to application of organic manures. Among the treatments, 75% RDF + 20 t FYM + 20 kg Sea weed extract granules + 5 t neem cake ha-1 (T8) exhibited better performances of growth and yield parameters of chilli cv. Indus 13. The maximum values of growth parameters such as plant height, leaves plant-1, branches plant-1, canopy volume, chlorophyll content in the leaves and net photosynthetic rate were observed in this treatment (T8). The yield parameters such as days to first flowering, days to 50% flowering, flowers plant-1, fruit set, fruits plant-1, fruit length, fruit girth, pericarp thickness, pulp seed ratio, single fruit weight, total fruit yield (28.18 t ha-1) and quality parameters like capsaicin content (0.76%) and ascorbic acid content (171.3 mg g-1) were highest in this treatment (T8) suggested this is the best integrated nutrient management combination for chilli. Application of 100% RDF (160 : 30 : 30 kg ha-1) proved inferior in respect of growth and yield of chilli.
