“…In contrast, O v may be of limited use because of its low nutrient content and availability in Myanmar. Clearly, the combined application of organic manures and inorganic fertilizers can enhance soil N content for cultivating rice and improve both long term productivity [51] and ecological sustainability [52]. A major advantage of using organic wastes is that they can provide a variety of nutrients at low cost.…”

We investigated the effect of combining organic and inorganic fertilizers on the growth and yield of hybrid rice (Palethwe-1) in the dry and wet seasons of 2015. Four quantities of inorganic fertilizer were used in the main plot [0%, 50%, 75%, and 100% nitrogen, phosphorus, and potassium (NPK)] based on the recommended amounts of 150 kg N ha ] as part of a split-plot experimental design with three replicates. In both seasons, significant differences in growth parameters including number of tillers hill −1 , soil-plant analysis development (SPAD) values, total dry matter, yield, and yield components were observed in plants supplied with different inorganic fertilizers. The 100% NPK (I 100 ) fertilizer produced the maximum yield but similar yields were achieved in plots supplied with 50% NPK (I 50 ) and 75% NPK (I 75 ). Significant differences in growth and yield parameters were also found in crops supplied with organic manures. Although identical quantities were supplied, O p produced the best growth parameters in both seasons including total dry matter, yield, and yield components. O c also performed well. Combining inorganic and organic fertilizers demonstrated that I 50 together with O p (5 t·ha −1 ) provided similar growth, total dry matter, and yield parameters to I 100 in both seasons. O c (5 t·ha −1 ) plus I 75 also achieved similar yields to I 100 . This study demonstrates that the combined application of inorganic fertilizers and organic manures has the potential to reduce chemical fertilizer usage without decreasing the yield of hybrid rice, and can enhance the growth, yield, and yield components of Palethwe-1.

“…To get a high yield by limiting the use of chemical fertilizers and supplementing them with organic-based fertilizers is a new concept for sustainable agriculture. Integrated use of fertilizers for high-yielding crops can decrease dependency on chemical fertilizers (Zia et al, 1992).…”

Bioslurry obtained from biogas plants has the potential to reduce the use of expensive chemical fertilizers and increase yields. A field experiment was conducted to investigate the growth response and yield production of okra fertilized with various combinations of bioslurry and nitrogen fertilizer. The experiment was planned according to randomized complete block design with 3 replications. Bioslurry was analyzed for its composition and was applied at the rate of 600 kg ha -1 along with 50%, 75%, and 100% of the recommended dose of N fertilizer for the production of okra. Phosphorus and potassium fertilizers were added according to recommended rates per hectare. Compared to inorganic N alone, the application of bioslurry alongside NPK fertilizers applied at reduced rates significantly increased the okra fruit yield as a consequence of 14%-31% enhanced plant height, 12%-14% additional branches per plant, and 25%-36% more fruits per plant. Moreover, bioslurry improved root length by 13%-45%, which resulted in an increased N uptake by plants and improved N use efficiency. Our results suggest that the application of bioslurry alongside reduced rates of N fertilizer is a viable strategy for the sustainable production of okra, especially under semiarid climatic conditions.

“…Further rice straw is also burnt as a source of fuel. Sesbania is one of the most suitable green manure for the wheat -rice rotation provided it is sown around May 20 and allowed to grow for 40 days; while, rice may be transplanted in 2nd week of July [Zia et al (1992a)]. Unfortunately, this practice is very limited.…”

The fertility status and physical condition of these systems can be improved by using green manure that will help in realising high yields of crops [Zia et al (1992a)]. Moreover, legumes also help sustain soil fertility through following ways: (1) potential to make substantial contribution to the nitrogen economy of the cropping system; (2) often exert favourable influence on several other soil fertility parameters through their extensive and deep root systems; (3) have ability to extract nutrients from deep soil layers; (4) utilise insoluble or fixed form of nutrients like phosphorous, and make them available to the succeeding crops; and (5) crops like sesbania and their incorporation improves physico-chemical properties of saline-alkali soils leading to increased growth and yields of subsequent crops [Ladha et al (1996)].…”

Total geographical area of Pakistan is 79.61 million hectares (m.ha.). Area under cultivation is 21.59 m.ha.; of which, only 5.34 m.ha. (i.e., 25 percent) is free from soil limitations and is fit for intensive agriculture [Mian and Mirza (1993)]. The remaining agricultural lands have various types of problems including formation of slow permeability, water logging, salinity and sodicity, and wind and water erosion. Thus, on an average, three out of four hectares of cultivated land in Pakistan are in poor health. This in turn is causing temporary or permanent decline in the productive capacity of the land. Therefore, poor soil health is posing serious threat to the sustainable growth of agriculture. The most important on-farm effects of land are summarised in Table 1.
