Abstract/ Executive Summary:

A study was undertaken to investigate the direct, residual and renewed effect of organic manures in combination with chemical fertilizers. In wheat-rice cropping pattern the experiment was conducted at Wheat Research Centre, Nashipur, Dinajpur dt.rlng 1997-98. The experiment was laid out in a randomized complete block Design with nine treatments and four replications of each treatment. The varieties for wheat and rice were Kanchan and BRRI Dhan- 32, respectively. The results indicated that the grain and straw yield responded significantly to chemical fertilizers and organic manures. The yield increased with the. Increasing NPKSZn upto the recommended dose. The organic manure had direct and residual effect on grain yield and . the performance of PM was better than FYM. Rice yield obtained due to renewed PM/FYM alone with 75%. NPKSZn were not encouraging due to lodging at the anthesls stage.

Location: Wheat Research Centre (WRC), Nashipur, Dinajpur

Start Date: 15-10-1997

End Date: 30-03-1998

Program Area: Farming System

Commodity: Fertilizer

Objectives:

To observe the performance of integrated use of poultry manure (PM), farm yard manure (FYM) and chemical fertilizers in wheat-rice cropping pattern.

Methodology:

The experiment was carried out at Wheat Research Centre (WRC), Nashipur, Dinajpur during 1997-98. The soil was sandy loam in texture with pH value of 5.0, organic matter 1.0%, total N 0.09%, available P 10.2 ppm,. exchangeable K 68.0 ppm, available S 11.5 ppm and available Zn 1.3 ppm. The experiment consisted of nine treatments and laid out in. a randomized complete block design with four replications. The lay out of the plots was kept undisturbed for growing the following rice crop. ThP. unit plot size was 6m x Sm. The treatments for wheat were control (T₁), 100% NPKSZn (T₂), 75% NPKSZn (T₃), 75% NPKSZn + FYM (T₄), 75% NPKSZn + FYM (T₅), 75% NPKSZn (T₆), 75% NPKSZn +PM (T₇), 75% NPKSZn +PM (T₈) and 75% NPKSZn (T₉). In case of rice the treatments were control (T₁), 100% NPKSZn (T₂), 75% NPKSZn (T₃), 75% NPKSZn (T₄), 75% NPKSZn + FYM (T₅), 75% NPKSZn + FYM (T₆), 75% NPKSZn (T₇), 75% NPKSZn + PM (T₈) and 75% NPKSZn + PM (T₉). For rice, FYM (Farm yard manure) and PM (Poultry manure) were excluded from the treatments T₄ and T₇ to observe the residual effect and FYM and Pincluded to T₈ and T₆ to see the direct effect of FYM and PM, respectively. Both crops, wheat and rice received FYM and PM in the treatments T5 and T 8 to evaluate the effect of double application (Renewed application in rice) of organic manures, The country's recommended dose of fertilizers represented by 100%. These rates for wheat were 100 kg N, 20kg P, 50kg K, 15kg S and 4kg Zn ha^-1 and the rates for rice were 70kg N, 10kg P, 33kg K, 20kg Wheat variety, Kanchan (Triticum aestivum L.) and rice variety, BRRI Dhan 32 (Oriza sativa L.) were used as experimental crops. Wheat seed @ 120kg ha^-1 was sown on 7 December, 1997 and the crop was harvested at maturity on 5 April, 1998. Thirty-seven day old seedlings of rice were transplanted on 29 July, 1998 and the crop was harvested at maturity on 9 November, 1998. Intercultural operations such as weeding, irrigation and plant protection measures were taken as and when necessary. Data were statistically analyzed following the F-test and the mean comparisons were made by.DMRT at 05% level. Sand 3kg Zn ha^-1. Organic manures, both PM and FYM were incorporated @ 10 t ha^-1 to soil 15 days before seeding of wheat and transplanting of T. aman rice.

Achievement/Findings:

Wheat experiment Grain and straw yield: Grain yield increased significantly as compared to control due to addition of chemical fertilizers and organic manure. The data showed that grain yield increased significantly with increasing levels of NPKSZn up to 100% recommended dose. Reduction of NPKSZn dose to 75% of recommended significantly decreased the grain yield compared to 100% NPKSZn although it was higher than control. Grain and straw yield of rice: Grain yield of rice was remarkably influenced by added chemical fertilizers and organic manures. It varied from 2756 kg ha^-1 to 3969 kg ha^-1 irrespective of treatments where the lowest yield was obtained in control. The highest yield obtained with 75% NPKSZn+PM (Direct) was significantly higher than all other treatments except the 75% NPKSZn+PM (Residual) treatments.
