Response of wheat growth and yield to various levels of compost and organic manure


Farm Table says:

This paper has some great significance in the current situation that other third world countries are facing. Since Pakistan still has some of the poorest rural areas up to this day, this will help other regions with the same issue maximize their resources. For other countries, this is a huge help on how to minimize their waste and put it to good use instead.

The organic matter is used since times to improve soil health and supplying plant nutrients. Various types and sources of organic wastes are utilized in agriculture but most of these materials remain unutilized, especially in resource-poor countries. These practices pose a serious threat to the environment and loss of useful pool of plant nutrients. Pakistan is facing a severe challenge of acute food and energy crisis and sufficient food production at least for ever-growing population at 2.6 percent per annum should be made possible by the use of all available resources

The present investigations were, therefore, performed to compare raw organic manure, compost and inorganic fertilizer for wheat growth and yield.

Organic manures are traditionally used for supplying plant nutrients. Their volume and other operational problems forced the farmers to use inorganic fertilizers. The recycling of organic waste is considered one of the major solutions to get rid of huge piles of wastes. The product obtained provides nutrients in an efficient way along with improving the soil conditions.

Because the current practice of using inorganic fertilizers may not fulfill and maintain the soil quality needed for sustainable crop production.

• The impact of organic manure and compost on the productivity of wheat (Triticum aestivum L. cv. Inqlab-91) was investigated in sandy clay loam soil.

• The amounts of various organic manures to supplement the inorganic fertilizers must be optimized to increase crop yield.

• Changes in growth and yield parameters of wheat relative to inorganically fertilized controls were measured.

Organic amendments had positive but variable effects.

• The organic manure application increased the wheat yield by 11.13 (105 %) to 13.53 (128 %) g pot–1, relative to the control.

• The wheat plant height, number of tillers, spike length, straw yield, grain yield and 1000-grain weight all were statistically different from that of control.

• The findings of the trial suggested that crop productivity may be improved significantly by the application of various organic manures for a longer time.

Hence, instead of using inorganic chemical fertilizer alone, the integrated use could be more effective and sustainable for environment and agriculture.

The present investigations have demonstrated the improvement of wheat growth and yield with the use of organic manure and compost when they were compared with chemical fertilizer. It is quite possible to get higher wheat yield by the integrated use of organic and inorganic fertilizers. This will result in soil quality improvement, which should be investigated under field conditions.
