Abstract
An experiment was done at the Soil Science Department, Bangladesh Agricultural University (BAU) to study the joined use of banana leaves with inorganic potassium fertilizer on the development and yield of BRRI dhan49 placing Randomized Complete Block Design (RCBD) with eight treatments and three replications. The treatments were T1: control (no fertilizer), T2: RFD (Recommended Fertilizer Dose), T3: (50% K from banana leaves+50% K from MoP) , T4: (60% K from banana leaves+40% K from MoP ), T5: (70% K from banana leaves+30% K from MoP), T6: (80% K from banana leaves+20% K from MoP), T7: (90% K from banana leaves+10% K from MoP), T8: (100% K from banana leaves).The uppermost potassium content in grain (0.33%) and straw (1.30%) were gained in the treatment T3 and T4 .The bottommost potassium content in grain (0.26%) and straw (1.08%) were logged in the control. At the same time, the highest potassium uptake by grain (19.46 kg ha-1) and straw (89.06 kg ha-1) were attained in the treatment T3 and the lowest potassium uptake by grain (8.67 kg ha-1) and straw (51.40 kg ha-1) were documented in the control. Total (grain+straw) peak (108.52 kg ha-1) potassium uptake was found in T3 treatment and lowest (60.06 kg ha-1) was found in control. It can be endorsed to cohesive use of 50% K from banana leaves+50% K from MoP on nutrient content and uptake of BRRI dhan49.
Highlights
The illustrative grain and straw samples were dehydrated in an oven at 65°C for about 24 hours before they were crushed by a grinding machine
The highest K content was originated in treatment T3 (50% K from banana leaves + 50% K from MoP) which was statistically alike to the treatment T4 (60% K from banana leaves + 40% K from MoP)
The results existing in table 4 showed that potassium uptake by grain and straw of rice (BRRI dhan49) wide-ranged significantly due to different treatments
Summary
The main provider of plant nutrients is soil It has been using chemical fertilizers year after year for higher yield. Annual potassium rich crops like banana is used as green manure throughout the world It is very common in Bangladesh and its leaves comprise considerable amounts of K and other nutrients . Increasing rate of potassium to a rice crop at the time of sowing specified that grains yields, K uptake and soil available K content were increased (Roy and Mathur, 1989). Influence of Banana Leaves in Association With Inorganic Potassium Fertilizer on The Nutrient Content And Uptake of Brri Dhan. The present inquiry was assumed to study the effect of joined use of banana leaves with inorganic fertilizer on nutrient content and uptake by BRRI dhan
