A field experiment was conducted in spring planted sugarcane at Sugarcane Research Station, Buralikson, Assam, India during 2014-15 and 2015-16 to evaluate the response of promising mid-late maturing sugarcane genotypes under three levels of fertilizers. Three mid-late maturing promising genotypes, viz. CoBln 14504, CoBln 14505, CoBln 14506 along with a recommended variety CoBln 94063 as check were tested under three levels of NPK fertilizers i.e. 75% RD of NPK, 100%RD of NPK and 125% RD of NPK (135:70:60). Result revealed that among the tested genotypes, CoBln 14505 recorded significantly the higher cane yield (66.50t/ha), NMC (68.10 thousand/ha) over the check as well as other two genotypes. In case of fertilizer, 125% recommended dose of NPK recorded significantly higher cane yield (62.91 t/ha) than the both 75% and 100% recommended dose of NPK.

A field experiment was carried out at Agricultural Research Station, Vizianagaram, during Kharif, 2016 under rainfed conditions to know the fertilizer responsiveness of promising finger millet varieties to graded doses of NPK fertilizers. Twenty treatment combinations were tested in split- plot design with three replications. Experimental results revealed that with 125% RDF grain yield increase was 10%, 27% and 48% higher than 100% RDF, 75% RDF and 50% RDF respectively. Among the finger millet genotypes, grain yield of VL-379(2037 kg/ha) and VL-352(1989 kg/ha) was significantly high and was at par with national check variety VR-708(1959 kg/ha). Both the test varieties (VL-379 and VL-352) were far superior to local check variety in terms of growth and yield characteristics. Higher net monetary returns and B:C ratio were obtained with VL-379, followed by VR-708 and VL-352 at 125% RDF.

The aim of this work was to evaluate the changes of different sulphur forms (soluble, adsorbed) in chernozem soil in a long-term field experiment supplied with increasing doses of NPK fertilizers for a long time. In addition, other objective of this study included the examination of the applicability of recommended extractants of the different sulphate fraction in Hungarian soils. A long-term field experiment was established at the Research Station of Látókép of the University of Debrecen in 1984. In addition to control, two levels of NPK fertilizer doses have been used with irrigated and non-irrigated variants. Winter wheat and corn were cropped in a crop rotation on plots. Soil samples were collected in three different development stages of winter wheat, at the stage of stem elongation (April), flowering (May) and ripening (June of 2018) from the topsoil (0–20 cm) of experiment plots. Water-soluble inorganic sulphate was extracted with 0.01M CaCl2 solutions. The soluble plus adsorbed sulphate was extracted with 0.016M KH2PO4 solution. Sulphate was measured by turbidimetric method. 0.01M CaCl2-SO42— ranged between 0.293–1.896 mg kg-1 and the 0.016 M KH2PO4-SO42- varied between 5.087–10.261 mg kg-1. The values of KH2PO4 SO42- was higher than that of CaCl2-SO42-, because KH2PO4 extracted the adsorbed and soluble fractions of sulphate, while CaCl2 extracted the soluble sulphate fraction. The amount of absorbed sulphate was calculated by the differences of KH2PO4- SO4 and CaCl2-SO4. The KH2PO4 characterizes mainly the adsorbed sulphate fraction much more than the water-soluble fraction. KCl is the most widely used extractant for the determination of plant available sulphate content of soil in Hungary; therefore, KCl-SO42- fraction also was determined. The KCl-SO42- ranged between 0.328–2.152 mg kg-1. The CaCl2-SO42- and KCl-SO42- fractions were compared and based on Pearson's linear correlation, moderate correlation was established (r=0.511) between them. In all three extractant (0.01M CaCl2, 1M KCl, 0.016 M KH2PO4) higher sulphate fractions were measured in the fertilized plots where superphosphate had been supplied for ages until 2010. The arylsulphatase activity of soil also was determined and ranged between 9.284 and 26.860 µg p-nitrophenol g-1 h-1. The lowest value was observed in the treatment with highest NPK2 dose, both in irrigated and non-irrigated areas.

A Field experiment was conducted on effect of various levels of potassium application on soil potassium fractions and sugarcane yield at Regional Agricultural research station, Anakapalle, Andhra Pradesh. The experiment comprised six treatments and four replications in Randomized Block Design. The treatments comprised of T1:Control (0 K), T2:50% Recommended dose of Potassium (60 kg K/ha),T3:75% Recommended dose of Potassium (90 kg K/ha),T4:100% Recommended dose of Potassium (120 kg K/ha),T5:125% Recommended dose of Potassium (150 kg K/ha) and T6:150% Recommended dose of Potassium (180 kg K/ha). Results revealed that number of milliable cane, cane yield (t/ha) and sugar yield (t/ha) was found to be significantly high with treatment receiving 150% recommended dose of fertilizers (79855, 82.12 t/ha and 12.04 t/ha respectively), however, it was statistically on par with the treatments receiving  125% recommended dose of potassium fertilizers(79855,82.12 t/ha and 12.04 t/ha respectively) and 100% recommended dose of potassium fertilizers application (79315,81.86 t/ha and 11.57 t/ha respectively). Increasing levels of K significantly increased all the K fractions. However, highest value of water soluble K (29.5 mg kg-1 at 0-15 cm depth and 31.6 mg kg-1 at 15-30 cm ) exchangeable K (205 mg kg-1 at 0-15 cm depth and 228 mg kg-1 at 15-30 cm depth) non-exchangeable K (854 mg kg-1 at 0-15 cm depth and 971 mg kg-1 at 15-30 cm depth), lattice K (2110and 2381 mg kg-1 at 0-15 and 15-30 cm ) and total K (3267 and 3718 mg kg-1) were recorded with the application of with the application of 150% recommended dose of potassium application (180 kg ha-1) followed by application of 125% recommended dose of potassium application (150 kg ha-1) . The sequential order of dominance of different fractions of K were lattice K>nonexchangeable K> exchangeable K and water soluble K. The per cent contribution of different fractions of K to total K were followed in the order of lattice K (64.02 to 74.94% at 0-15 and 15-30 cm depth), non-exchangeabl K (15.46 to 17.79% at 0-15 and 26.4 to 27.43 % 15-30 cm depth), exchangeable K (6.32 to 8.39% and 5.60 to 7.69% at 0-15 and 15-30 cm depth), and water soluble K (0.81-0.90% and 0.69 to 0.85% at 0-15 and 15-30 cm depth) There exists positive and significant correlation among various K fractions indicating dynamic equilibrium.

Abstract Niger (Guizotia abyssinica Cass.) is an important minor oil seed crop grown in dry areas grown mostly by tribal and interior places as life line of tribal segment. Tribal people mainly use its oil for cooking purpose, above than that there were also other uses. Hence, the niger crop should be protected from the infection. The crop is affected by number of fungal diseases. Therefore, a field experiment was formulated for three years with the four replications at the Niger Research Station (NRS) at Navsari Agricultural University (NAU), Vanarasi, Navsari (Gujarat) on the foliar diseases of GN-1 variety of niger crop. In this experiment, six different fungicides along with one control have been evaluated to control the Alternaria and Cercospora leaf spot diseases, out of which all the fungicidal treatments were significantly superior over the control. Here, foliar spray on the incidence of diseases was compared with the control (without any treatment). All the fungicidal treatments were significantly superior over the control to reduce Alternaria and Cercospora leaf spot diseases of Niger crop. Treatment of Carbendazim + Mancozeb (0.2 %) with two sprays first from the initiation of the disease and second after the interval of 15 days recorded the lowest incidence of Alternaria (14.56) and Cercospora (14.94) leaf spot diseases of niger and recorded the highest seed yield 337 seed yield kg/ha along with the net return with cost benefit ratio graph.

Sowing Dates

A field experiment was conducted during kharif, 2005 at Agricultural Research station, Devihosur, Haveri, Karnataka to assess the progress of powdery mildew at different time interval of sowing dates. Totally 20 different dates of sowings were imposed in the experiment at an interval of 10 days. The crop sown on last week of May to mid of June recorded minimum disease severity compared to rest of the date of sowings. This clearly indicated that crop sown during this period suffers less, which may be due to low inoculum potential, whereas late sown crop suffers more because of the readily available inoculum in the early sown crops. Low disease severity in last week of May to mid of June sowing may be attributed to the non-congenial weather factors for the development of the disease.
