Influence of various organic manures with chemical fertilizers on increasing growth, yield and nutritional quality of potato was studied. The experiment consisted of seven treatments including T0: Control, T1: 75% recommended fertilizer dose (RFD); T2: 100% RFD, T3: 75% RFD + Kazi compost (5 t/ha), T4: 75% RFD + Kazi compost (3 t/ha), T5: 75% RFD + Poultry manure (3 t/ha) and T6: 75% RFD + Cowdung (5 t/ha). Among the organic manures, Kazi compost performed the best which compensated up to 25% of recommended inorganic fertilizers and significantly improved the growth components, yield parameters, tuber yield and nutrient uptake by potato. In field performance, Kazi compost @ 5 t/ha was effective followed by poultry manure and can be recommended for better growth, yield and nutritional quality of potato. Bangladesh J.

There are many of rice field which is located near the industrial area. The industrial waste contains heavy metals (chromium) which will cause contamination of rice if the waste isn’t treated properly. The used of chemical fertilizers can cause chromium contamination. It needs an effort to do remediation, such as using phytostabilization mechanism. This research aimed to determine the role of chelator in chromium phytostabilization and its influence on the growth and quality of rice. The study was conducted in Waru village, Karanganyar in May to October 2018.  This research was factorial design used completely randomized block design with two factors, namely chemical fertilizers and chelator (<em>Agrobacterium </em>sp. I<sub>26</sub>, and manure). The parameters observed are chromium content and uptake by plant tissues (roots, shoot and rice), plant height and a number of clumps. Research output was without chemical fertilizer-chelator <em>Agrobacterium </em>sp. I<sub>26</sub> that can increase the chromium uptake in roots as big as 95.38 %, increased up to 10 %  in the shoot and decreased up to 92.38 % in rice compared to control. Application of <em>Agrobacterium</em> sp. I<sub>26</sub> can be recommended to produce good quality and quantity of rice (good growth and free from harmful pollutants such as chromium metal).

Abstract A new glass fertilizer (GF) system of main composition 60P2O5.30K2O.3.5ZnO. 3.5MnO.3Fe2O3 was developed in response to the needs of pea plants with bio-fertilizers (Rhizobium leguminosarum. Bv.vicieae, Bacillus megaterium var phosphaticum, Bacillus circulans).GF was prepared by the traditional melt quenching technique at 1150°C. Characterization of prepared system was done using FTIR spectra before and after immersion in a simulated actual agriculture medium like 2% citric acid and distilled water. During two winter seasons, two successful field experiments were conducted at Cairo University's Eastern Farm to determine the impact of chemical, glass, and bio-fertilizers on plant growth, yield attributes, and seed quality of pea plant. Control treatment were without any addition of recommended chemical fertilizers and other treatments were full dose of recommended chemical fertilizers (100%RDF), glass fertilizers at rate 60 kg fed− 1, Glass fertilizers at rate30 kg fed− 1, 50% RDF ,100%RDF + bio-fertilizers, Glass fertilizers at rate 60 kg fed− 1 + bio-fertilizers, glass fertilizers at rate 30 kg fed− 1+ bio-fertilizers, 50%RDF + bio-fertilizers. Plots received 60 kg fed− 1 glass fertilizers + bio-fertilizers show the highest significant increment in plant growth, number and weight of pods plant− 1, number of grain pods− 1, grain yield, biological yield, P%, k% in pea leaves and quality of pea seeds compared with plots without any addition (control) in both seasons.
