A pot experiment was carried out during autumn growing season of 2016-2017 at the Gerdarasha field of College of Agriculture Engineering Sciences, to study the effect of three dominant soil orders (Mollisols (M), Vertisols (V) and Aridisols (A)), five levelsof applied triple super phosphate (TSP) fertilizer (0, 80, 160, 240 and 320 kg TSP ha-1) and combination between them on chemical availability of phosphorus (P) using solubility diagram at elongation stage and wheat yield. The factorial experiment was depended using a completely randomized design (CRD) with three replicates. The results indicated that the soil orders were affected on phosphorus status, it has appeared that the studied soil order was located between TCP and HA for both Aridisols and Vertisols it means the solubility of phosphorus is low. but in Mollisols is slightly more than Vertisols and Aridisols. It is the P-status and availability was very low since shifting towards TCP, it means precipitation of P in a non-available form then decrease in its availability. The application of phosphorus fertilizers caused shifting the points towards a more soluble form of phosphorus. The results indicated that the application of TSP fertilizer increased the solubility of P in the studied dominate soil orders. Then, the treatment combination (M, V, A) TSP0 were the nearest point to TCP falling between TCP and OCP which were the lowest soluble of phosphorus there less available, phosphorus application of phosphorus caused to shifting towards DCP In contrast, for treatment combination (M,V and A) TSP320 kg ha-1 were located between OCP and DCP the nearest point treatment combination for DCP

The interactive effects of lime and phosphorus on maize growth in an acid soil were investigated in a greenhouse experiment. A completely randomized design with 12 treatments consisting of four lime levels, 0, 2, 10, and 20 t ha−1, in a factorial combination with three phosphorus rates, 0, 30, and 100 kg ha−1, was used. Maize was grown in pots for six weeks and its heights and dry matter yield were determined and soils were analyzed for available P and exchangeable acidity. Liming significantly reduced the exchangeable acidity in the soils. The effect of lime on available P was not significant but available P increased with increasing P rates. There was a significant effect of lime, P, and P by lime interactions on plant heights and dry matter. Without lime application, dry matter increased with increasing P rates but, with lime, dry mattes increased from 0 to 30 kg P ha−1but declined from 30 to 100 kg P ha−1. The highest dry matter yield (13.8 g pot−1) was obtained with a combined 2 t ha−1of lime with 30 kg P ha−1suggesting that lime application at low rates combined with moderate amounts of P would be appropriate in this soil.

Two experiments were carried out to determine the bioavailability of phosphorus in two spray-dried yeasts - sugarcane yeast (SCY), and sugarcane yeast + brewer's yeast (SCBY) - in starting pigs, by comparing different methods (Apparent Digestibility Coefficient of Phosphorus - ADCP; True Digestibility Coefficient of Phosphorus - TDCP; slope ratio; and standard curve). In experiment I, a digestibility assay were carried out using 30 cross breed pig with initial weigh of 22.69 ± 4.24kg, allotted in a completely randomized design. The mean ADCP and TDCP values were 62.68 and 64.15% for SCY and 77.01 and 79.33% for SCBY. ADCP and TDCP for SCBY were higher (P<0.05) than the values for SCY. In Experiment II, a growth test was conducted, 56 crossbred piglets, were utilized, with initial live weight of 15.11 ± 3.43kg, allotted in a completely randomized design, with seven treatments, four replications, and two pigs per experimental unit. The treatments consisted of a basal diet without supplementation with P and the same diet including supplementation with two levels of P (0.053% and 0.105%) from dicalcium phosphate, SCY and SCBY. The relative bioavailability mean value of 57.23% for SCY and 91.96% for SCBY, corresponding to 0.30% and 0.40% of available phosphorus, respectively.

Balanced nutrient supply is important for the sustainable crop production. We evaluated the effects of nutrient management practices on soil properties and crop yields in rice (Oryza sativa L.) - rice - wheat (Triticum aestivum L.) system in a long-term experiment established at National Wheat Research Program (NWRP), Bhairahawa, Nepal. The experiment was designed as a randomized complete block experiment with nine treatments and three replications. Treatments were applied as: T1- no nutrients added, T2- N added; T3- N and P added; T4- N and K added; T5- NPK added at recommended rate for all crops. Similarly, T6- only N added in rice and NPK in wheat at recommended rate; T7- half N; T8- half NP of recommended rate for both crops; and T9- farmyard manure (FYM) @10 Mg ha-1 for all crops in rotation. Results of the study revealed that rice and wheat yields were significantly greater under FYM than all other treatments. Treatments that did not receive P (T2, T3, T7, T8) and K (T2, T4) had considerably low wheat yield than treatments that received NPK (T5) and FYM (T9). The FYM lowered soil pH and improved soil organic matter (SOM), total nitrogen (TN), available phosphorus (P), and exchangeable potassium (K) contents than other treatments. Management practices that ensure nutrient supply can increase crop yield and improve soil fertility status.Int. J. Appl. Sci. Biotechnol. Vol 5(1): 42-50

On natural acidic soil, statistically significant relationships between wheat yield and pigment content in leaves were established (for Chl a r = 0.910…0,949; Chl b = 0.925…0,967; for carotenoids in 2017 = 0.887;). Nitrogen fertilizer promoted an increase in pigment content in leaves (Chl a and Chl b - by 38…43%, carotenoids - by 16…22%). At phosphorus application, the content of chlorophylls increased by 44…83%, carotenoids - by 20…37%. The content of mobile phosphorus in the arable layer of natural acidic soil is statistically significantly associated with the content of Chl b (r = 0.738 and 0.793 for 2017 and 2020, respectively) and the part of pigments included in light-harvesting complexes (r = 0.799 and 0.829, respectively). In 2020, statistically significant associations of mobile phosphorus content in soil and weight ratios of Chl a / Chl b (r = -0.815) and (Chl a + Chl b) / carotenoids (r = 0.840) were noted. Soil liming reduced the influence of phosphorus on the pigment complex of leaves: against a natural background, the increase in Chl content was 27…40%, against a limed background – 27…29%; for Chl b - on the contrary, liming increased its content by 93…108%, while on a natural background - only by 63…84%. On both soil backgrounds, the addition of phosphorus reduced the carotenoid content in wheat leaves (on a natural background - by 7…9%, on limed - by 17…23%).

Kata kunci: Azolla, Kompos, Pertumbuhan, Rumput Raja ABSTRACT Research with experimental method aims to examine the effect of combination dose of organic compost fertilization and the addition of Azolla on the growth of king grass (Pennisetum purpureophoides). From April 1 to September 30, 2020, research was conducted on agricultural land, Beji Village, Kedungbanteng District, Banyumas Regency. The experiment used a completely randomized design with a factorial pattern with the first factor being the dose of organic compost, namely 10, 20, and 30 tons ha-1, and the addition of Azolla, namely 10, 20, 30 percent of the first factor, resulting in 9 treatment combinations. Each treatment combination was repeated three times to produce 27 experimental units. The king grass plant in the second cutting was planted on ??400 square meters with a spacing of 80 x 40 cm. The organic compost used is derived from beef cattle dung that has finished the composting process, and Azolla comes from rice fields. Research parameters measured were plant height and stem diameter measured on days 14, 28, and 42 days. The data that had been obtained were then analyzed using analysis of variance (ANOVA) and continued with the orthogonal polynomial test. The results showed that the dose of compost had a very significant effect (P<0.01) on plant height and stem diameter, while the application of Azolla fertilizer also had a very significant effect (P<0.01) on plant height and stem diameter, but the interaction had no effect significant (P>0.05). Dosage of organic compost can be used to achieve the best king grass growth of 30 tons ha-1 and the addition of Azolla by 30 percent of the dose of organic fertilizer.

Municipal solid waste (MSW) may be a potential substitute for peat substrate in soilless medium. Adequate N and P are needed for a complete composting of MSW. MSW piles treated with diammonium phosphate (MSWP) or without P on Mar. 1994 were cured for 5 months. In Fall 1994, a factorial treatment combination of nine mixes and 3 fertigation treatments were evaluated in a completely randomized design on soft-pinched, single-stem `Red Sail' poinsettia. Mixes were MSW or MSWP ranging from 33% to 100% by volume in 1 peat: 1 perlite (v/v) and Sunshine mix was used as the control. Fertigation treatment began on the 1st, 2nd, or 3rd week after potting. Fertigation solution contained 266 mg·liter–1 N from 30N–4.4P–8.8K. The total fertigations ranged from eight to 10 for the 13-week study. With MSW mixes, shoot dry mass at the week 1 fertigation was 36% larger than at the week 3 fertigation. At the week 3 fertigation, shoot dry mass with 100% MSWP was ≈53% greater than with the 100% MSW. Shoot dry mass with 100% MSWP was similar to the control at the week 1 fertigation.
