Effects of Organic Amendments (Rice Hull, Cow Owl Sawdust) On Cultivated Corn Production in the University Site "Lwama"

A field trial was carried out with rice (BRRI 64) grown in saline soil at Kuakata of Patuakhali District to evaluate the potential of rice straw, rice hull and saw dust each applied at the rates of 0, 4, 8 t ha-1 in moist and saturated conditions. Growth parameters and yield of rice were found to increase significantly (p ≤ 0.05) with the increased rates regardless of kinds of organic treatments under both the conditions. The highest plant heights (89 cm in moist and 101 cm in saturated condition) were recorded at maturity in the treatment, which received the combination (RH8RS8SD8) of highest rates of these 3 organic amendments. The lowest plant heights (73 cm in moist and 77 cm in saturated) were recorded in control condition (RH0RS0SD0). The maximum numbers of tillers were observed in RH8RS8SD8 and RH8RS4SD8 followed by RH8RS8SD4, RH8RS4SD4 and RH4RS8SD8 treatments at saturated condition. The straw dry matter and grain yields of rice were also found to vary significantly (p ≤ 0.05) due to single application of rice hull, rice straw, saw dust and moisture conditions but their combined effects were found to be significantly better at the higher levels. The highest grain yield (6.6 t ha-1) was recorded in RH8RS8SD8 treatment followed by RH8RS8SD4, RH8RS4SD8, RH8RS4SD4 and RH4RS8SD8 at saturated condition. Growth and yield of rice were attained better at saturated condition than that of the moist soil. Asiat. Soc. Bangladesh, Sci. 43(2): 197-206, December 2017

The Individual

The potential and effectiveness of the indigenous organic amendments such as rice hull (RH), rice straw (RS) and sawdust (SD) at the rates of 0, 2 and 4 t ha-1, respectively on N, P and K contents of BRRI Dhan-47 grown on saline soil under variable moisture (field moist: FM and 2-5 cm standing water: SW) levels were evaluated in the field experiment. The N, P and K contents in the shoot at maturity stage of rice increased significantly (p<0.05) by the individual and the combined application of these amendments. The maximum contents of N (26.7 g kg-1: FM and 25.7 g kg-1: SW) were attained by the T27 (RH4SD4RS4) followed by the T26 (RH4SD4RS2) treatments. Among the three types of amendments regardless of their doses, the application of RS exerted best response (16.75 g N kg-1) followed by SD (16.35 g N kg-1) and RH (16.04 g N kg-1) in increasing N content of rice plants at field moist condition of the soil. The maximum P contents (2.49 g kg-1: FM and 2.67 g kg-1: SW) were recorded by the T27 (RH4SD4RS4) followed by the T26 (RH4SD4RS2) treatments and the lowest contents of P (0.40 g kg-1: FM and 0.42 g kg-1: SW) were obtained from the control plots. The content of P in rice shoots was slightly higher in SW than that of FM conditions. The maximum contents of K (18.2 g kg-1 in FM and 15.8 g kg-1 in SW) were obtained by the application of RH4SD4RS4 (T27) followed by the RH4SD4RS2 (T26) and the lowest contents of K (2.8 g kg-1: FM; 2.7 g kg-1: SW) were determined in the control plots. The contents of N and K in rice shoots were slightly higher in the FM than those of the SW conditions regardless of these amendments.Bangladesh J. Sci. Ind. Res.53(4), 297-304, 2018

The study was conducted at Kuakata of Patuakhali to evaluate the impacts of indigenous organic amendments such as rice hull, rice straw and saw dust alone and in combination under variable moisture conditions (moist and saturated) on the primary nutrients (N, P and K) of BRRI dhan64 grown in a coastal saline soil. The individual application of rice hull, rice straw and saw dust at the rate of 0, 4 and 8 t/ha and their combined effects were found to be significant (p ≤ 0.05) for N content in the rice plants. Effects of the treatments on phosphorus content alone and in combination were slightly additive but not significant. The maximum P content in the plant tissues was determined at saturated condition with the increased rate of the treatments (T27 = RH8RS8SD8), while the lowest content of P was recorded in control (T1 = RH0 RS0 SD0). The K content in plant tissues increased significantly (p ≤ 0.05) with the increased rate of application of rice hull, rice straw and saw dust. The higher K contents were found under saturated condition of soil. Under moist condition of soil, the highest contents of N, P and K were 21.3, 1.45 and 15.67 g/kg, respectively and under saturated condition, the highest contents of N, P and K were 23.4, 1.78 and 15.87 g/kg by the combined application of rice hull, rice straw and saw dust, respectively at the rate of 8 t/ha, suggested that the primary nutrition of rice had better response under saturated moisture condition in saline soil, which received rice hull, rice straw and saw dust.Bangladesh J.

N Fertilizer Rate

Maintaining soil fertility and the use of plant nutrient in sufficient and balanced amounts is one of the key factors in increasing crop yield and decreasing adverse environmental effects and pollutions arising from nonpoint fertilizer usage. The effects of time and rate of nitrogen application on phenology and some agronomical traits of corn (Zea mays L.) were investigated at the research farm of the University of Mohaghegh Ardabili. The trial was laid out in a split plot design based on a randomized complete block scheme with three replications. Experimental factors were nitrogen fertilizer at four levels (0, 75, 150, and 225 kg ha–1) in the main plots and three levels of nitrogen application time [(1/3 at sowing + 1/3 at V8–10 + 1/3 at tasseling), (1/2 at sowing + 1/2 at tasseling), and (1/2 at sowing + 1/4 at V8–10 + 1/4 at tasseling) as T1, T2, and T3, respectively] as subplots. The results showed that the maximum values of grain yield and its components, days to 50% tasseling (63.85 days), days to 50% silking (68.2 days), days to physiological maturity (128.9 days) were observed in the plots treated with 225 kg N ha–1 as T1. The maximum nitrogen use efficiency (38.16 kg kg–1) was obtained at application of 75 kg N ha–1 as T1, and the minimum values of this index (19.41 kg kg–1) were obtained in the plots that received 225 kg N ha–1 as T2. Based on the results, it was concluded that application of the highest N fertilizer rate (225 kg ha–1) in three equal splits can be recommended for profitable corn production.

The experiment was carried out with rice (BRRI dhan48) grown in saline soil at the premises of the Department of Soil, Water and Environment, University of Dhaka to evaluate the impacts of agricultural amendments, such as rice hull (RH), rice straw (RS) and sawdust (SD) each applied at the rates of 0, 4 and 8 t ha-1 in moist (80% moisture) and saturated soil conditions. Most of the growth and yield components of rice were found to increase significantly (p ≤0.05) with the increased rates regardless of kinds of organic treatments under both the moisture levels. The tallest plant heights (99 cm in moist, 105 cm in saturated condition) were recorded at maturity stage of rice with the RH8RS8SD8treatment, which received the highest rates of these three organic amendments. The shortest plant heights (79 cm in moist; 86 cm in saturated conditions) were recorded in control pot (RH0RS0SD0), where no amendment was made. The maximum numbers of tillers were observed in RH8RS8SD8followed by RH8RS8SD4, RH8RS4SD8, RH4RS8SD8 and RH4RS4SD8 treatments at saturated condition. The straw dry matter and grain yields of rice were also found to vary significantly (p ≤0.05) by the individual application of rice hull, rice straw, sawdust and moisture conditions, but their combined effects were found to be highly significant at their higher doses of combination. The highest grain yield (4.4 t ha-1) was recorded in RH8RS8SD8 treatment followed by RH8RS8SD4 (4.2t ha-1) and RH8RS4SD8 (4.1t ha-1) at saturated condition. Harvest index and 1000 grain weight of the rice were attained positive under both the moisture conditions, but at saturated condition of the soil, the amendments (RH, RS and SD) produced better response for these components compared to those of the moist soil condition.

Tomato is one of the most profitable crops in the Philippines and is extensively cultivated throughout the world. However, its production faces different pest and disease problems, particularly bacterial wilt which greatly reduces yield. Two separate studies were conducted simultaneously in a single factor experiment arranged in randomized complete block design (RCBD) with three (3) replications. The studies were conducted to evaluate the effects of the different soil organic amendments on the growth and yield of tomato in the open field (Study I) and under protective structure (Study II) with the following treatments: control, cabbage waste, carbonized rice hull, chicken dung, hagonoy, wedelia, and wild sunflower. Protective structure grown plants had better protection against detrimental heavy rain and strong light intensity, thus had better performance in terms of lower bacterial wilt infection and weed incidence, higher percentage survival, enhanced flowering, and a higher yield than those grown in the open field. On the other hand, only the weight of marketable fruits and total yield were enhanced by the application of the different soil organic amendments. All amendments had similar effects but were superior than the control. Protected cultivation gave a higher net return than the open field. In particular, sunflower amended plants under structure were the most profitable, by almost 8 times compared to the open field.

Corn Production

Alternative to the use of synthetic nitrogen fertilizers can be the utilization of a natural organic source of on-farm animal manure nutrients for the growth, development and production of agricultural crops. The main objective of this research was to compost the poultry manure with organic amendments and utilize for sweet corn production. The composition of composted and uncomposted poultry manure was compared and field experiments were conducted during 2002 and 2004 at Randolph farm of Virginia State Univ. located near Petersburg, Virginia. The field experiments included seven treatments: control with un-composted manure, four treatments with manure (composted with wheat straw turned weekly, composted with wheat straw turned bi-weekly, composted with clover hay turned weekly, and composted with clover hay turned bi-weekly), recommended rate of N fertilizer, and a control without any treatment. Results indicated that composting of poultry manure with an organic amendment such as wheat straw or clover hay helps poultry manure's transformation into a usable fertilizer material for supporting crop production. However, use of clover hay was observed to be desirable than wheat straw for sweet corn production. Addition of clover hay resulted in significantly increased ear fresh and dry weight and also resulted in taller plants. The affects of biweekly vs. weekly turning compost on performance of sweet corn were not significant.

Growth Performances

A pot experiment was conducted using BRRI Hybrid Dhan-6 variety of rice at the premises of the Department of Soil, Water and Environment, University of Dhaka, Bangladesh to evaluate the capabilities of rice hull (RH: 0, 2, 4 t ha-1) and pistia (PT: 0, 400, 800 kg ha-1) for the improvement of growth performances of rice grown under field moist (FM: 70% moisture) and 2 - 5 cm standing water (SW) conditions in saline soil. Among the vegetative growth, the plant heights, number of productive tillers, fresh shoot and shoot dry matter weights were found to be increased significantly (p ≤ 0.05) with the increased rates of rice hull and pistia treatments, and the increments were more striking by their combinations in most of the cases under both FM and SW conditions. The tallest plant heights (112 cm in FM and 120 cm in SW) and the maximum number of productive tillers (13 in FM and 16 in SW) were recorded at maturity stage of rice in the T8 (RH4PT8) treatment where rice hull and pistia were applied at the highest (RH: 4 t ha-1, PT: 800 kg ha-1) dosages. Based on superiority in both the plant heights and number of tillers, the amendments can be arranged in the sequence of T8 > T7> T6> T5> T2> T3>T4> T0 > T1. The analysis of variance on these data indicated that in the standing water condition, fresh shoot and shoot dry matter weights of rice plants were found to be increased significantly (p ≤ 0.05) by the application of the higher rates of the treatments and their combinations. Thus, the application of indigenous organic amendments such as, rice hull and pistia showed significant contribution for the growth performances of rice under variable moistures but further researches are needed under variable soil and climatic conditions to ensure food security under saline soil.
