Incubation experiment was conducted to obtain infomiation on tlie extent of acidity developed due to added AlCI, (0, 25, 50 and 100 tig g ') at different pH levels and changes in exchangeable A1 in peat. Results showed ...

Mineralization of N in ihe presence ofO to 2000 mg kg ' each of Co. Ni and Cu as chlorides in peat was studied. Tliese s;dts of metals did not produce any significant change in tlie proccss of niLrificalion and ammonificalion ...

In a study on the effect of urea with depths in rice {Oryza sativa Linn.), conversion of urea into NHj-N was maximum at 15 days in most of the treatments and into NOj-N was at 7 days. But with surface placement of urea it ...

The of feel of iilumiiiiiimon atnniDnificalion and nilriHcalion was slucliod in a series of incubalionsof peal with ;uk1 williout added (Nll,)jSO,. Addition of AlCI, (0, 200, 4(X), 600 jig A! « ') caused a iionsigniricaiii ...

Free.living nitrogen fixing bacterial isolates were purified from eleven soil samples representing eight typical zones of Bangladesh. The isolates were categorized on the basis of their colonial, morphological and ...

Nitrification under acid conditions in peat was studied. Application of lime increased nitrification in commercial peat. Release of mineral nitrogen increased rapidly with pH. A significant amount of NH4-N was released up ...

Foliar application of potassium naphthenate, gibberellic acid and nutrients made separately, or in combination with nutrients caused significant increase in various growth indices (except height and leaf number) and yield ...

A field experiment following a pirtie.lly c D n t o u n d e d design w j s conducted to study the effect of NPK fertilizers on the oil and N, P, K, Ca and Mg contents of mustard seeds. Fertilizers showed an increase in oil ...

Application of N alone produced a considerable increase in vegetative growth. However, N in the presence of P resulted comparatively higher growth. The best growth was recorded where 90 kg N and 44 ka/ha each of P and K ...

A field experiment was carried out to monitor the relative efficiency of urea, urea formaldehyde (UF), sulphur coated urea (SCU) and isobutylidene diurea (IBDU) each at the rate of 40, 80 and 120 kg N/ha on growth, yield ...
