A field experiment was conducted on fine texture soils to find out the effect of different sources of nutrients on secondary (Ca and Mg) and micro nutrient (Fe, Mn, Cu and Zn) content in rice at various growth periods. The experiment was laid out in a randomized block design in kharif season with four treatments and replicated five times. The treatments consisted of M1 (RDF - Control), M2 (10 t FYM ha-1 + RDF), M3 (1.5 t vermicompost ha-1 + RDF), M4 (Green manuring + RDF). The nutrient content in rice at various growth periods was significantly increased with the application of 100 % NPK in combination with FYM @ 10 t ha-1. However, it was on par with that of green manuring together with 100 % NPK during both the years of the study.

Aim: To study the amelioration of zinc deficiency in blackgram (Vigna mungo L.) through soil applied zinc in Typic Haplustepts soil of Rajasthan. Methodology: A two year field experiment was undertaken during Kharif 2016 and 2017 at Instructional Farm (Agronomy), Rajasthan College of Agriculture, Udaipur, Rajasthan. The treatments comprised application of Zn to soil @ 3 kg Zn ha-1, 4 kg Zn ha-1, 5 kg Zn ha-1 and 6 kg Zn ha-1. The experiment was laid out in a randomized block design with four replications. Results: Application of zinc significantly (P=0.05) increased the number of nodules per plant, number of pods per plant, number of seeds per pod, seed yield, haulm yield, biological yield, nutrient (N, P, K & Zn) content and uptake, protein content, net return and B:C ratio in blackgram. Soil application of Zn@5 kg ha-1 significantly increased seed yield, haulm yield and biological yield by 72.53, 50.08 and 57.68 per cent over the control in pooled analysis, respectively. However, the effect of application of Zn@5 kg ha-1 on yield attributes, yield, nutrient content, uptake, quality and economics of blackgram was found statistically at par with the application of 6 kg Zn ha-1. Interpretation: The application of Zn@ 5 kg ha-1 along with the recommended dose of fertilizer (NPK) resulted in significantly (P=0.05) higher productivity, nutrient uptake, quality and profitability of blackgram under Typic Haplustepts soil of Rajasthan.

ABSTRACT Sewage sludge is rich in organic matter and nutrients for the plants, and can be used in pineapple production, but there are few studies with scientific evaluation of possible inorganic and biological contaminants in pineapple plantations. In view of the above, this study aimed to evaluate the contamination of the soil and in fruits of pineapple fertilized with sewage sludge. The study was conducted in the municipality of Janaúba-MG. Treatments were arranged in a randomized block design, with four replicates, in a 2 x 5 factorial scheme, consisting of two different fertilizers: sewage sludge (SS) and mineral fertilizers (MF), and five pineapple varieties (Pérola, Vitória, Smooth Cayenne, MD-2, Fantastic IAC). Nitrogen was adopted as the base element to calculate the sewage sludge dose in the pineapple crop. Fertilization with sewage sludge increased the Zn and Cu contents in the soil and the Zn content in the leaves of the pineapple plants. Sewage sludge did not change the contents of As, Pb, Ba, Cu and Zn in the fruit, and Cr, Ni and Cd contents were not detected by the method used. Pineapple fruits did not show microbiological contamination above the limits established by the Brazilian legislation.

A Doctoral Research was conducted for two consecutive years (2011-2012 and 2012-2013) on fine texture soils of agricultural college farm, Bapatla to find out the residual effect of different sources of nutrients applied to preceding rice on P content in maize at different growth stages. The experiment was laidout in a Randomized Block Design in Kharif season with four treatments. The treatments consisted of M1 (RDF - Control), M2 (10t FYM ha-1 + RDF), M3 (1.5t vermicompost ha-1 + RDF), M4 (Green manuring + RDF). During the immediate Rabi, the experiment was laid out in a split-plot design without disturbing the soil for succeeding maize with the four treatments given to Kharif rice as main plot treatments and each of these divided into five sub-plots to receive five levels of fertilizer NPK application viz., N1 - 75%NPK, N2 - 100% NPK, N3 - 125% NPK, N4 - 150% NPK and N5 - 175% NPK for succeeding maize. Data collected on P content in maize at different growth stages was significantly increased with the application of 100% NPK in combination with FYM @10t ha-1 to preceding rice crop, irrespective of the NPK levels applied to succeeding maize crop. However, it was on par with that of green manuring together with 100% NPK during both the years of the study.

Winged bean (Fabaceae) is a tropical crop that has high nutrient content, and almost all parts of the plant are edible. The research aimed to evaluate the growth and production of winged bean in an intercropping system with tomato. The study was conducted at the Cikabayan Experimental Field of Bogor Agricultural University, Bogor, Indonesia, in a randomized block design with three replications during the rainy season of December 2017 to June 2018. Winged beans were planted in high and low population densities and intercropped with three tomato genotypes, “Tora”, F70030081-12-16-3 and “Apel Belgia”. Monoculture winged bean was assigned as control. Tomatoes were planted between the rows of the winged beans in the intercropping treatment. The results showed that the growth of winged bean in monoculture and intercropping systems was not significantly different. The photosynthetic activity of winged bean at three to five weeks after planting remained high, indicating that the vegetative growth was optimal in both systems. Intercropping increased the winged bean number of pods per plant by 12.66-19.52% compared to monoculture, irrespective of population density. Therefore, winged bean could be considered as suitable to grow in intercropping systems.

Dist. Ahmednagar (Maharashtra) India. The experiment was carried out in Randomized Block Design with seventeen genotypes and one check variety i.e. N-2-4-1 treatments replicated three times. In storage studies results indicated that, the minimum storage losses (Sprouting losses (%), Rotting losses (%), PLW losses (%) & Total losses) were recorded by the genotypes T7, T11 and T10.The minimum sprouting losses (after 6 month storage) was recorded in genotype T11 (1.41 %). It was followed by genotype viz. T7 and T10 (1.51 %). The maximum sprouting losses (after 6 month storage) was recorded in genotype T17 (4.06 %). Rotting losses (after 6 month storage) ranged between T11 (3.19) to T4 (7.46) per cent. The minimum PLW loss was recorded in genotype T7 (14.98 %), followed by genotype viz. T11 (15.64 %), T10 (15.85 %) and T6 (17.16 %). The maximum PLW loss was recorded in genotype T17 (33.26 %). The minimum total losses (after 6-month storage) was recorded by genotype T11 (21.34 %). While the maximum total losses (after 6-month storage) was recorded in T4 (36.49 %). Considering the above results, it could be concluded that, among the seventeen genotypes T7 (RHROR–7), T10 (RHROR–10) and T11 (RHROR–11) found promising for further evaluation.

Aim: To determine the effect of integrated use of inorganic phosphorus along with phosphorus solubilising bacteria and farmyard manure on nutrient Content and uptake in Bt-Cotton. Study Design: The experiment was laid out in randomized block design with three replications. Place of Study: At College Farm, Agricultural College, Bapatla, Guntur district. Methodology: After the preliminary layout, the Tulasi-BG II hybrid of cotton was used as a test crop, with a spacing of 90 cm x 60 cm in the experimental site. Plant samples were collected at 45, 90 DAS, and harvest. Plant samples were shade dried and kept in hot air oven at 75°C until a constant weight was obtained. Samples were powdered and then analysed using standard chemical procedures. Results: The uptake of macronutrients viz., N, P, and K was markedly influenced by the treatments with maximum values recorded by the treatment that received 60 kg P2O5 ha-1 + FYM + PSB. Their uptake significantly differed with increase in dose of phosphorus applied at all growth stages. Combined use of 60 kg P2O5 ha-1 + FYM + PSB resulted in a significant increase in uptake of all micronutrients (Zn, Cu, Mn, and Fe) at all stages except Cu at 90 DAS. Conclusion: Application of phosphorus combined with FYM and PSB not only reduce inorganic phosphorus fertilization but also enhance the uptake of nutrients and plant nutrient content by providing favourable conditions for plant growth. Application of 30 kg P2O5 ha-1+ PSB + FYM was found to be on a par with addition of only 60 kg ha-1P2O5. Hence the P dose can be reduced to half by integrating with PSB and FYM.
