Abstract/ Executive Summary:

The experiment was carried out in medium highland at South Surma, Sylhet during rabi season of 2010-2011 to study the effect of bio-slurry and integrated use of bio-slurry along with inorganic fertilizer on the performance of cabbage grown in AEZ- 20. The experiment was laid out in a randomized complete block design replicated thrice with four treatments viz. T₁: Soil test based inorganic fertilizer dose for high yield goal (HYG), T₂: Cowdung @ 5 t ha^-1 + Integrated Plant Nutrient System (lPNS) based inorganic fertilizer for HYG, T₃: cowdung bio-slurry @ 5 t ha^-1 + IPNS based inorganic fertilizer dose for HYG and T₄: Farmers practice (average of 20 farmers surveyed). Results showed that individual head weight, head diameter and head yield of cabbage significantly influenced by the treatments. The highest head yield (73.50 tha^-I) was obtained in cowdung bio-slurry @ 5 t ha^-1 + IPNS basis inorganic fertilizer dose (T₃) followed by T₁ (58.7 4 t ha^-1), where in farmers practice (T₄) produced lower yield (54.77 t ha^-1). Economics analyses revealed that the gross (TK.257250/ha) and net return (TK.194628/ha) were higher in T₃. The BCR was also higher (4.10) under the same treatment. Similar trend was followed is case of BCR (4.10).

Commodity: Bio fertilizer

Objectives:

To analyze the effect of bio-slurry and integrated use of bio-slurry along with inorganic fertilizers on the performance of cabbage crop grown in AEZ- 20.

Methodology:

The experiment was conducted at farmers field of Bibidoil, Lalabazar, South Surma, Sylhet under Estern Surma-Kushiyara Floodplain (AEZ- 20) during the rabi season of 2010-11 to find out the effect to properly managed bio-slurry and integrated use of bio-slurry along with inorganic fertilizer on the performance of Cabbage. Before conducting the experiment, nutrient packages (soil test basis) for each treatment was calculated on the basis of Land and Soil Resources Utilization Manual for South Surma, Sylhet. The experiment was conducted is RBD with replicated thrice. There were four treatments viz. T₁ = Soil test based (STB) inorganic basis fertilizer dose for high yield goal (HYG), T₂= Cowdung (CD) @ 5 t ha^-1 + IPNS basis inorganic fertilizer dose for HYG, T₃= Cowdung bio-slurry @ 5 t ha^-1+ IPNS basis inorganic fertilizer dose for HYG and T₄= Farmers practice (average of 20 farmers). Dominant variety Atlas-70 of cabbage was selected by the cooperator farmer and used in the trial. Unit plot size was 30 m². Cowdung, cowdung bio-slurry, TSP, 1/3rd of MoP were applied at the final land preparation treatment wise. Urea and 2/3rd of MoP were applied in three times viz: 10, 25 days after transplanting (DAT) and at heading stage. But in farmers practice, all fertilizers were applied at the final land preparation. The crops were planted on 02 December 2011. Intercultural operations viz. weeding, irrigation and spraying insecticides were done as and when required in order to support normal cabbage growth and development. The crop was harvested after full maturity. Prior to harvest five (05) plants were selected randomly from each plot and uprooted carefully for collecting data on yield and yield contributing characters. The collected data were analyzed statistically following the ANOVA technique with the help of MSTAT- C software. The mean differences among the treatment means were adjudged by Least Square Difference (LSD).

Achievement/Findings:

Considering the yield, as well as return, the treatment CD bio-slurry (5 t ha^-1) along with IPNS based inorganic fertilizer for HYG showed better than others. Cost and return analysis also revealed that the higher gross and net returns as well as BCR was found in T ₃ treatment (CD bio-slurry @ 5 t ha^-1 with IPNS based inorganic fertilizer for HYG). This treatment (T₃) could be recommended for cabbage production for its higher yield, benefit as well as sustain soil fertility in AEZ- 20 in Sylhet.
