Drip Fertigation

A field study was conducted at experimental farm of Interfaculty Department of Irrigation Water Management, Post Graduate Institute, M.P.K.V., Rahuri, Maharashtra, India during Rabi season of 2014-15. The experiment was laid out in randomized block design with eight treatments and three replications. The treatments consisted of four levels of fertilizer application as 100%, 75%, 75% with foliar sprays and 50% recommended dose (RD) under drip fertigation (DF) and compared with conventional irrigation and conventional fertilizer application. The significantly higher yield (52.62 t ha-1) of tomato was obtained in DF with 100% RD and it was at par with DF with 75% RD + 3 foliar sprays, DF with 100% RD, N and K drip, P through soil and DF with 75% RD. The drip method had lowest water use (458.4 mm) as compared with 878.6 mm in surface irrigation method. The treatment consisting DF with 100% RD provided net seasonal income (Rs. 3,93,311 ha-1), net extra income over control (Rs.1,52,056 ha-1). The maximum B:C ratio (3.96) was observed in DI with 100% RD, N and K drip, P through soil followed by DF with 100% RD. The fertigation with 75% RD in 18 weekly splits as per schedule is the best treatment for improved growth, yield and water productivity of tomato (var. Abhinav) cultivated in silty clay loam soils of Western Maharashtra.

<p>Soils of the southern Guinea savanna zone of Nigeria are inherently infertile due to shortened fallow period and the continuous use of inorganic fertilizer which depletes the soil of micronutrients such as zinc over time. A field trial was carried out at the Teaching and Research Farm of the University of Ilorin, Nigeria during the 2016 and 2017 cropping seasons to evaluate the effect of zinc and NPK fertilizer on the growth, yield and zinc concentration of seeds of sesame. The experiment was laid out as a factorial fitted into a randomized complete block design (RCBD), replicated thrice. The treatment consisted of four levels of ZnSO<sub>4</sub> (0, 5, 10 and 15 kg ha<sup>-1</sup>) and four levels of NPK 15:15:15 (0, 100, 200 and 300 kg ha<sup>-1</sup>). Data collected were subjected to analysis of variance (ANOVA) and means were separated using new Duncan multiple range test at 5 % level of probability. Results obtained showed significant effects of Zn and NPK rates on plant height, number of leaves, yield per plot and yield per hectare. The application of 15 kg ha<sup>-1</sup> Zn and 300 kg ha<sup>-1</sup> (15:15:15) NPK resulted in high yield and high zinc content of seeds.</p>

Field experiments were carried out at the Bangabandhu Sheikh Mujibur Rahman Agricultural University, Gazipur during 2000-2002 to evaluate the effect of N and P applicaiton on the root growth, leaf photosynthesis and yield of groundnut (var. Basantibadam). Four levels of N (0, 20, 40 and 60 kg N/ha) and four levels of P (0, 13, 26 and 39 kg P/ha) were the treatment variables. The trial was set up in a randomized complete block design under factorial arrangement with three replications. Application of N and P fertilizer exerted significant effects on root development, photosynthesis, yield contributing characters and pod yield of the crop. Plant receiving 60 kg N and 39 kg P/ha had larger root system, greater photosynthetic rate and better yield contributing characters that resulted in the maximum pod yield which, however, was not significantly different from N60P26 treatment. Hence, it is recommended that higher yield of Basantibadam can be obtained from N60P26 kg/ha in salna silty clay loam soil of Madhupur tract (AEZ 28) of Bangladesh.DOI: http://dx.doi.org/10.3329/bjar.v32i3.538Bangladesh J.

Background: Pigeonpea is second most important pulse crop grown after chickpea in India. Pigeonpea is versatile crop can be grown in vast agro climatic condition with low input. Although the yield is very less as compare to the potential yield, so we need to increase the yield of pigeonpea using modern techniques such as drip fertigation and mulching. Both these techniques are resource saving and realized maximum yield as compare to conventional practices. Methods: The experiment was laid out in factorial complete randomized block design with three replications. The experiment consisted of two levels of irrigation (0.50 CPE and 0.75 CPE) as one factor and three fertility levels (100% RDF,75% RDF and 50% RDF) as second factor and two levels of mulching (without mulching and with plastic mulching 25 micron) as third factor. Result: The results revealed that the combination of higher level of irrigation with 100 per cent RDF and with plastic mulching recorded significantly higher seed yield, water productivity and B.C ratio compared to the rest of the treatment combination.

A field experiment was conducted to study the effect of harvest time and dosage of organic fertilizer application on the yield of carrot (Daucus carota L.). This research was conducted at the experimental garden plants owned by Faculty of Agriculture, University of Winaya Mukti, in Tanjungsari, Sumedang. The height of this location is 850 meters above sea level with type C precipitation (rather wet). This research was conducted from January 2013 to April 2013.The design used in this research was a randomized block design (RBD) with factorial pattern consisting of two treatment factors i.e. the time of harvest (W) and organic fertilizers dosage (P) which were repeated 2 times. The first factor (W) consistedof four levels i.e. (w1) = 90 HST, (w2) = 100 HST, (w3) = 110 hst, and (w4) = 120 HST. The second factor (P) consists of four levels which are (p0) = 0 tonnes haˉ¹, (p1) = 10 tons haˉ¹, (p2) = 20 tons haˉ¹,and (p3) = 30 tons haˉ¹.This  experiment showed that there is no interaction between the application of thechicken coop organic fertilizer dosage with the harvest of the crops of carrot. However, treatment given to the 20 tons haˉ¹ dose of chicken coop organic fertilizer affected the weight of fresh roots, long tubers, the diameter of the bulbs, and the levels of vitamin C. Because the required application of the fertilizer will show the weight of fresh tubers larger, long tubers longer, heavier bulb diameter, and showed an increase in levels of vitamin C.Treatment of HST 100 time harvest affected the fresh tuber weight and the content of vitamin C, because this treatment is as needed; which then will show a heavier bulb  diameter, as well as elevated levels of vitamin C.

Mango is one of the most cultivated tropical fruits worldwide and one of few drought-tolerant plants. Thus, in this study the effect of a sustained deficit irrigation (SDI) strategy on mango yield and quality was assessed with the aim of reducing irrigation water in mango crop. A randomized block design with four treatments was developed: (i) full irrigation (FI), assuring the crop’s water needs, and three levels of SDI receiving 75%, 50%, and 33% of irrigation water (SDI75, SDI50, and SDI33). Yield, morphology, color, titratable acidity (TA), total soluble solids (TSS), organic acids (OA), sugars, minerals, fiber, antioxidant activity (AA), and total phenolic content (TPC) were analyzed. The yield was reduced in SDI conditions (8%, 11%, and 20% for SDI75, SDI50, and SDI33, respectively), but the irrigation water productivity was higher in all SDI regimes. SDI significantly reduced the mango size, with SDI33 generating the smallest mangoes. Peel color significantly changed after 13 days of ripening, with SDI75 being the least ripe. The TA, AA, and citric acid were higher in SDI75, while the TPC and fiber increased in all SDI levels. Consequently, SDI reduced the mango size but increased the functionality of samples, without a severe detrimental effect on the yield.

ABSTRACT: Grasshoppers of the families Acrididae and Romaleidae (Orthoptera) are among the insects that defoliate heliconias and have been gaining status as pests of commercial crops of these plants in Brazil. The objectives of the present study were to identify the grasshopper defoliating heliconias in the municipality of Santo Antônio de Pádua, RJ (Brazil), to evaluate the effect of different levels of shade on the population of this grasshopper and the production parameters of heliconias, and to determine if this grasshopper has an oviposition preference among the heliconias evaluated. The experiment was in a completely randomized block design, in subdivided plots (four levels of shade in the plot, 0%, 30%, 50% and 80%, and four species of Heliconia: H. psittacorum, H. stricta, H. wagneriana and H. psittacorum x H. spathocircinata ‘Golden Torch’ in the subplot), with four replications. The grasshopper was identified as Cornops frenatum frenatum (Acrididae). An increase in shade resulted in a decrease in the number of oviposition holes from the grasshopper and the number of lateral buds. Shade did not influence the number of C. f. frenatum nymphs and adults and the number of flower stems. H. wagneriana was the most preferred species for oviposition by C. f. frenatum. Results suggested using screens to shade heliconia plants can help control C. f. frenatum populations, however, the light requirements of the heliconias should be considered to guarantee productivity.
