A field experiment was conducted at Post Graduate Institute Instructional Farm of Mahatma Phule Krishi Vidyapeeth, Rahuri, during rabi 2017-2018 to study the effect of different levels of phosphorus and zeolite on yield and its use efficiency and availability of nutrients. There were eight treatments replicated thrice in RBD. The significantly highest bulb with 150% of the recommended dose of P2O5 175 kg along with 120 kg ha-1 of zeolite application followed by the zeolite @ 120 kg ha¬¬¬¬¬¬-1 + 125% P2O5of RDF. However, the highest phosphorus use efficiency was observed in the treatment with 75% P2O5 of RDF and recommended dose of nitrogen and potassium fertilizers along with 120 kg ha-1zeolite and 20 t ha-1 farm yard manure. The available nitrogen, phosphorus and potassium were significantly higher in treatment with zeolite @ 120 kg ha-1 + 150% P2O5 of RDF. Thus recommended dose of phosphatic fertilizer can be reduced by 25% when used along with 120 kg ha-1zeolite and recommended dose of nitrogen and potassium fertilizers for obtaining optimum yield of onion.

A field experiment was conducted to study the effect of different levels of customized fertilizer (CF) on soil nutrient availability, yield and economics of onion. The results revealed that the significantly highest plant height (57.77cm), stem diameter (6.03cm) and bulb diameter (15.13cm) at the time of harvest, fertilizer use efficiency,bulb yield (22.34 t ha-1) and benefit:cost ratio (2.56) of onion were recorded in 100 % recommended dose of NPK through CF in three equal split doses. The significantly highest available nitrogen (213 kg ha-1), phosphorus (14.42 kg ha-1) were recorded in 125 % recommended dose of NPK through CF in two equal split doses and available K (804 kg ha-1) in 100 % recommended dose of NPK through CF in three equal split doses over the rest of the other treatments. The application of 100% recommended dose of fertilizer (100:50:50 N:P2O5:K20 kg ha-1) either two or three splits through CF to onion appears to be improving soil fertility, yield and yield contributing character of onion and getting higher net monetary returns.

Abstract. The aim of the study was to assess the influence of different fertilizer doses on the content of macroelements (nitrogen, phosphorus and potassium) in dry biomass and grain of maize during the 2016 – 2018 period. A field experiment with fertilization of maize was carried out on Alluvial-meadow soil (Fluvisol) in the region of Tsalapitsa village, near Plovdiv. Three variants of mineral fertilization were studied V2 (N15P10K0), V3 (N20P15K0) and V4 (N25P20K0), and a control variant V1 (N0P0K0) – without fertilization. It was established that N% content in maize dry biomass was affected significantly by the variants of fertilization (18% of the variance). Significant differences (P≤0.05) between the control variant and all the variants of fertilization were established. Increasing the fertilizer dose, nitrogen content in dry biomass increased, too. The highest was the average content of nitrogen in maize leaves (0.94%), followed by the cobs (0.71%) and the lowest was the content in the stems (0.58%). Phosphorus and potassium content of dry biomass were affected significantly by the year of the study (10% and 9% of the variance, respectively). At the 7-8th leaf growth stage of maize, the highest nutrients content (N, P, K) in dry biomass were reported. With aging of plants the nutrient content in their biomass decreased. Nitrogen, phosphorus and potassium content in maize grain was significantly affected by the year of the experiment. Mineral fertilization had impact mostly on the nitrogen content of the grain, which was the highest in V3 variant, accepted as optimal – 0.66% on average.

The study was conducted in the nursery of Hort. Dept., College of Agriculture and Forestry, Mosul University, Iraq, during 2018 season to study the response of budded "Zaghinia" apricot on seedlings rootstock to bio, organic and chemical fertilizers, and their effects on seedling growth. The studied factors were as follows: Bio fertilizer Fulzyme (0,1and 2 g. seedling-1 ), organic fertilizer (Rice residue) (0, 1 and 2 kg. seedling-1 ) and DAP fertilizers (0, 5 and 10 g. seedling-1 ). The study was performed by using split-split plots within factorial experiment in randomized complete block design (RCBD), with 3 factors and 3 replicates, by using 6 seedlings for each treatment. Treatment means were compared by using Duncan multiple levels at 5% p. the most important results obtained were as follows: 1 and 2 gm.seedling-1 of bio fertilizer (Fulzyme) and Chemical fertilizer (DAP) at the levels 5 and 10 g. seedling-1 affected significantly resulted in a significant increase in soil available nitrogen, while the addition of organic fertilizer (rice residues) and for both levels 1 and 2 kg. Seedling-1 gave a significant increase in nitrogen, phosphorus, ready-made potassium and pH of the seedling soil, and the bilateral interaction had a significant role in the growth of seedlings, especially the treatment of the interaction between the fertilizer (Fulzym) and organic fertilizer (Rice residues), which have a significant effect in giving the best results in available nitrogen, phosphorus and potassium in the soil, and the triple interference also gave a significant increase in all studied traits.

A set of four experiments with increasing levels of the three main plant nutrients and liming were established in two lateritic soils at two locations in the coffee-growing area of Puerto Rico. Two coffee cultivars were used in the experiments. The results obtained can be summarized as follows: 1. Nitrogen levels significantly affected coffee yields of the Puerto Rico cultivar in a Catalina clay at Maricao grown under shade. 2. Phosphorus and potassium did not significantly affect the yields of these coffee cultivars at the two locations. 3. Liming did not significantly affect the yields.

Changes In Soil Properties

A two year experiment was conducted during kharif and rabi season of 2016-2017 and 2017-2018 at experimental site near Faculty of Forestry in main campus of Birsa Agricultural University, Ranchi, Jharkhand, India. Sole cropping and gamhar based agrisilviculture systems with four different intercrops (arhar, cowpea, greengram and mustard) were under investigation. To study the overall scenario of soil properties under agrisilviculture system, soil samples were analysed at different profile depths (0-15 and 15-30 cm) to measure the changes in soil properties under the influence of gamhar (Gmelina arborea) tree and intercrops grown in between. Soil pH, electrical conductivity (dsm-1), organic carbon (%), available nitrogen, phosphorus and potassium (kg ha-1) were found higher at the soil depth 0-15 cm as compared to 15-30 cm due to addition of organic residue on the surface soil. Soil OC, available N, P and K in 0-15 cm as well as in 15-30 cm profile was found to be statistically significant. It showed an increase from initial value in all the treatments in 2016-17 and 2017-18. The increase was more in gamhar based agrisilviculture system than in sole tree and sole crops in both the years.
