Soil fertility and maximum crop production can only be achieved through proper fertilization. Proper and balanced fertilization have a considerably positive effect on plant growth and yield. Due to continuous use of chemical fertilizers, the organic matter and nutrient content of the soil decreased gradually. Therefore, in modern era, agriculture scientists are now engaged to establish an agricultural system, which can not only lower the production cost, but also conserve the natural resources. Soil, as a source of nutrients, must be protected from various kinds of external factors, especially from the addition of fertilizers in excessive rates. Any degradation in the quality of soil can significantly produce many undesirable changes in the environment and also reduces the overall crop yield. So, the concoction of organic and inorganic fertilization is an alternative and most effective method for sustainable and cost-effective management for maximum crop production, without effecting the environment. The Integrated Nutrient Management provides an excellent opportunity not only for sustainability of the soil, but also enhances the overall crop productivity. The present review study was carried out with the main aim to evaluate the role of combined application of organic and inorganic fertilizers on wheat crop production. The outcome of the study concluded that combined application of both organic and inorganic fertilizers significantly improve the wheat crop production, as compared with the sole application of either organic or inorganic fertilizers.

The study evaluated the effects of organic and inorganic fertilizers on the growth and yield of two lowland rice varieties; determined the proper fertilizer combination; and evaluated the profitability of rice production as influenced by the combined application of organic and inorganic fertilizers. This was laid out in split plot arranged in a RCBD design with variety and fertilizer treatments as the main plot and subplot, respectively. Results revealed that the period from sowing to heading, shoot dry weight, number of filled grains per panicle and weight of 1,000 grains were significantly influenced by the variety. The yield, yield components and harvest index (HI) were significantly influenced by fertilizer application. A significant interaction effect was noted on the period from sowing to heading as observed that inbred rice (NSIC Rc212) headed late than hybrid (TH82). Plants applied with 120-60-60 kg ha-1 N, P2O5 and K2O produced taller height, larger LAI, longer panicles, more productive tillers and filled grains, and consequently highest grain yield and HI. These plants also produced the heaviest root and shoot dry weights resulting to higher root shoot ratio compared to unfertilized plants. Highest net income was obtained in plants applied with inorganic fertilizer at the rate of 120-60-60 kg ha-1 N, P2O5 K2O due to high grain yield. Irrespective of fertilizer treatments, inbred rice was more profitable than hybrid. Highest production cost was incurred in plants applied with pure organic fertilizer due to the high cost of the material.

Organic And Inorganic Fertilizers

Development of an integrated nutrient management strategy is needed to enhance soil quality and increase crop yields in the marginal uplands of Eastern Visayas. Due to very poor soil condition, a field fertilizer experiment using the combined application of organic and inorganic fertilizers was conducted in Inopacan, Leyte, to assess the growth performance of corn plants. The six treatment combinations used in this study were the following: T1(no fertilizer added); T2(National recommendation for corn at 90-60-60 kg N, P2O, K5O ha-1); T3(chicken dung at 15 tons ha-1); T4(vermicast at 15 tons ha-1); T5(1/2 of inorganic + chicken dung at 7.5 tons ha-1) and T6(1/2 of inorganic + vermicast at 7.5 tons ha-1). Generally, application of organic fertilizer significantly increased soil pH, organic matter and total nitrogen. In addition, the treatments significantly increased, plant height, ear length, number of grains per ear, weight of 1,000 seeds, fresh stover yield, and grain yield of corn Corn plants in plots applied with fertilizer following T2 (National Recommendation for corn at 90-60-60 kg N, P2O, K5O ha-1) and T5(1/2 of inorganic + chicken dung at 7.5 tons ha-1) grew taller and developed larger ears with more kernels per ear and heavier 1,000 seeds which resulted to higher grain yield. However, using inorganic fertilizer alone had the same effect on ear length, number of kernels per ear of those corn plants applied with combination of either chicken dung or vermicast and one-half of inorganic fertilizers. Plants in control plots and those amended with vermicast alone showed the least growth responses.

Organic And Inorganic Fertilizers

Organic manures are eco-friendly alternatives to inorganic fertilizers. However, a large volume of organic inputs is needed to meet the nutritional requirements of crops. Hence, there is a need to combine them with inorganic fertilizers to attain better crop yield. This study was conducted to evaluate the effects of the combined application of organic and inorganic fertilizers on the growth and yield performance of sweetcorn and on the profitability of sweetcorn production. The treatments were as follows: T0 - -1 Control (without fertilizer applied), T1 - Inorganic fertilizer at 90-60-60 kg ha -1 -1 (N, P O , K O), T - 5 t ha of vermicompost + 45-30-30 kg ha N, P O , K O, T - 5 2 5 2 2 2 5 2 3 -1 -1 -1 t ha of poultry manure + 45-30-30 kg ha N, P O , K O, T - 5 t ha of cow 2 5 2 4 -1 -1 manure + 45-30-30 kg ha N, P O , K O, T - 5 t ha of goat manure + 45-30-30 2 5 2 5 -1 -1 -1 kg ha N, P2O5 , K2O, T6 - 5 t ha of mudpress + 45-30-30 kg ha N, P2O5 , K2O, T7 - -1 Foliar spray (Fermented Golden Snail) + 45-30-30 kg ha N, P O , K O. The 2 5 2 experiment was laid out in RCBD with 3 replications. Results showed that sweetcorn plants applied with organic + inorganic fertilizers regardless of source had comparable growth and yield performance to plants applied -1 with pure inorganic fertilizers. The highest net income of PhP62,086.00 ha was obtained from plants applied with combined goat manure and inorganic fertilizers. This suggests that in sweetcorn production, it is feasible to reduce the use of inorganic fertilizers by combining them with organic fertilizers
