Under rainfed rice-wheat cropping system, experiments were conducted on wheat variety Annapurna-2 from 1998 to 2002 to study the effect of continuous application of inorganic and organic fertilizers in longer run on wheat production and soil properties in alluvial soil of Khumaltar, Lalitpur at 1365 msal. Eleven different fertilizers combinations comprised of inorganic  and organic fertilizers were used. The results of the five-year experiment  indicate that the applications of optimal level of inorganic fertilizers could  supply the plant nutrients to wheat crop to produce sustainable yield. On the other hand, organic fertilizers could help to increase the crop yield and maintain soil fertility at the same time. Residual effect of available  phosphorus applied in previous rice crop had significant response on wheat yield. For maintaining soil fertility, application of FYM and incorporation of  crop residue into soil are worth practicable.Nepal Agric. Res. J.

Balanced nutrient supply is important for the sustainable crop production. We evaluated the effects of nutrient management practices on soil properties and crop yields in rice (Oryza sativa L.) - rice - wheat (Triticum aestivum L.) system in a long-term experiment established at National Wheat Research Program (NWRP), Bhairahawa, Nepal. The experiment was designed as a randomized complete block experiment with nine treatments and three replications. Treatments were applied as: T1- no nutrients added, T2- N added; T3- N and P added; T4- N and K added; T5- NPK added at recommended rate for all crops. Similarly, T6- only N added in rice and NPK in wheat at recommended rate; T7- half N; T8- half NP of recommended rate for both crops; and T9- farmyard manure (FYM) @10 Mg ha-1 for all crops in rotation. Results of the study revealed that rice and wheat yields were significantly greater under FYM than all other treatments. Treatments that did not receive P (T2, T3, T7, T8) and K (T2, T4) had considerably low wheat yield than treatments that received NPK (T5) and FYM (T9). The FYM lowered soil pH and improved soil organic matter (SOM), total nitrogen (TN), available phosphorus (P), and exchangeable potassium (K) contents than other treatments. Management practices that ensure nutrient supply can increase crop yield and improve soil fertility status.Int. J. Appl. Sci. Biotechnol. Vol 5(1): 42-50

Application of organic fertilizers in improving soil fertility has become a major factor that has enabled the world to feed billions of people. However, the required quantities of organic material are enormous, so it becomes necessary to combine different types of fertilizers to feed plants. The effectiveness of human feces compost (HC) alone, as well as in combination with single super phosphate (SSP), was evaluated in the present study. A field experiment was conducted at farmer field located in district Swabi (Pakistan). A total of eight possible treatments combination were arranged in randomized complete block design (RCBD), replicated four times. Two levels of human feces compost (HC), including control (HC0: control and HC1: 7.5 t ha-1) and four levels of P, as single superphosphate (SSP), including control (P0: control, P1:40 kg ha-1, P2: 60 kg ha-1 and P3: 90 kg ha-1) were utilized in the experiment. Results revealed that among all the treatments, combined application of SSP at 60 kg ha-1 along with 7.5t ha-1 HC significantly improved the growth, as well as the yield parameters of wheat crop. These results allow saving a half of usually made mineral fertilizer dose for the cultivation of wheat crop. Combined use of HC and SSP were strongly recommended for obtaining maximum wheat yield in the prevailing soil and environmental conditions.

Effect of lupin on wheat production and soil properties was evaluated on a red earth, at Wagga Wagga, N.S.W. Soil physical and chemical properties as well as soil surface aggregate stability, soil water distribution and extraction by wheat crops from a 10-year-old wheat/lupin (WL) rotation were compared with those of continuous wheat (WW), with (WW+N) and without (WW-N) nitrogen fertilizer application. Averaged wheat yield over the 1989-1990 period was 4.17, 2.95 and 3.06 t ha-1 respectively for WL, WW-N and WW+N. Despite the higher yield, important changes in soil properties have been detected in the soil under wheat/lupin rotation when compared with that under continuous wheat. The major effect was surface soil acidification and an associated loss of cations. Ten years of WL, compared with WW-N resulted in 0.2 unit reduction in pH (4 -35 v. 4.55) in 0.10-0.15 m with corresponding increases in extractable A1 and losses in exchangeable Ca2+ (17% as present in WW-N) and Mg+2 (12%). In the continuous wheat, annual application of 100 kg N ha-1 as urea resulted in much greater acidification (by 0.48 pH unit from 4.63 to 4.15 at 0.05-0.10 m) and larger losses in Ca2+ (up to 40%) and Mg2+ (up to 52%) in the top 0.2 m. Ten years of WL rotation reduced K+ by 10% in the top 0.2 m layer compared with both of the continuous wheat rotations, presumably due to higher export of K in lupin grains. Inclusion of lupin in the rotation also resulted in differences in the quality of soil organic matter. Despite similar total soil organic carbon content to WW-N, in the top 0.1 m, soil organic matter under WL had lower C/N ratio and higher polysaccharide content. Lower macroaggregate stability was found under WL compared to WW-N, but this did not result in lower soil water storage over the summer fallow during the two seasons of measurement. However, the wheat crop under WW utilized less stored subsoil water than that under WL, even under conditions of moisture stress.

The main focus of the study was to analyze trends and variability of wheat crop in Pakistan. Semi-log trend model was used to find trends and growth rate in area, yield and production of wheat crop whereas the variability was measured by Cuddy-Della Valle index of variability. The findings of the study illustrate that wheat area in Punjab, Sindh and Baluchistan was increased over the time whereas cultivated area of wheat in Khyber Pakhtunkhwa province was marginally decreased during 1981-85 to 2011-15. The results show that there was substantial increase in wheat yield and production in all four provinces of Pakistan. The increase in wheat yield may due to the adoption of new varieties of wheat in the country over the time. It was also concluded from the results that area and yield of wheat in Baluchistan recorded the highest degree of variability whereas in Punjab province area and yield of wheat crop were noticed the lowest degree of variability. Similarly, the maximum variability in wheat production was recorded for Baluchistan province followed by Sindh, Khyber Pakhtunkhwa, and Punjab. Mostly the variability in wheat production was due to the variability in wheat area and their yield.

ABSTRACT: Phytotoxic effects of allelopathic crop residues are important to trickle for their use as a source of organic amendments to improve soil fertility. In present study, through pots and two year field studies, we examined the integrated effect of allelopathic residues and NPK fertilizer treatments including T0 (control), T1 (200-150-100 kg NPK ha 1), T2 (100-75-50 kg NPK ha-1 + mung bean straw 4 t ha-1), T3 (100-75-50 kg NPK ha-1 + rice straw 4 t ha-1), T4 (mung bean straw 8 t ha-1) and T5 (rice straw 8 t ha-1) under different water regimes on soil fertility and wheat crop. Solo application of mung bean residue and rice straw caused significant inhibition of various germination and growth traits of wheat while minimal inhibition occurred when allelopathic straws were integrated with NPK fertilizer both under laboratory and field conditions, especially under 14 days of alternate wet/dry cycles. Among fertilizer treatments, mung bean residue caused a greater increase in soil organic carbon, available nitrogen and available phosphorus, while there was maximum percent increase in available potassium with T1 (200-150-100 kg NPK ha-1). Maximum increase in grain yield (30% and 33%) was achieved with T2 (100-75-50 kg NPK ha-1 + mung bean straw 4 t ha-1) during 2014-15 and 2015-16, respectively. Integration of allelopathic crop residues with inorganic fertilizers and alternate wet/dry cycles can help to reduce the possible phytotoxic effect of allelopathic residues for sustainable wheat production.

Akha biochar has the potential to exploit by farmer in Bangladesh. This study was undertaken to assess the perception of Akha biochar to utilize for wheat cultivation in the several farmer’s field of Bangladesh. This study aims to assess farmer’s adaptability on akha biochar for enhancing wheat production in Bangladesh. The utilization of Akha biochar as a source of nutrients supply for wheat production was investigated in this study. Akha Chula produced biochar was used as a Akha biochar source and the BARI Gom 28 was used as a testing plant. Five treatments like control (nothing was added), BARC (Bangladesh Agricultural Research Council) recommended fertilizer for wheat production, 5 kg/decimal biochar only, BARC recommended fertilizer plus 2.5 kg/decimal biochar and BARC recommended fertilizer plus 5 kg/decimal biochar. Same treatment was applied in three separate farmer’s field namely Mansur, Latif and Nayan. Among three farmers, Latif farmer field was highly fertile that resulted highest wheat productivity in several treatments. Result also showed that the BARC recommended dose with 2.5 kg biochar/ decimal produced highest wheat yield among the other treatments in all farmer’s field. These findings suggested that optimum level of Akha biochar amendments have potential benefits to improve soil fertility. The use of Akha biochar in addition to the chemical fertilizers in wheat production systems is an economically feasible and practical nutrient management practice. Our findings urged that reduction of chemical fertilizer application is possible with supplementation of Akha biochar. This study concluded that Akha biochar has the potential to improve soil fertility and productivity of wheat in Bangladesh.

The purpose of the research is comparative evaluation of drugs for pre-treatment of seeds as regulators of phytosanitary state of agrocenosis of spring wheat yield on different zoned varieties. The damage agrocnosises spring wheat in both years of observation all studied phytophages was below the EPV. On average data best to reduce crop damage striped flea beetles appeared variant NV_101 seed treatment less effective – preparations succinic acid, Appin Extra and Zircon. Among the varieties studied agrocnosises longer damaged by striped flea grade Kinelsky Otrada, less susceptible due to pre-sowing seed treatments were Kinelsky Niva and Kinelsky Anniversary. Chinch actively feeding during the growing during the 2015 compared with 2014, but to reveal the regularities of pre-treatment of seeds of spring wheat on the central leaf desiccation failed when feeding chinch. Presowing treatment of seed of spring wheat had a positive impact on reducing the number of sprout damage on the fly all the studied drugs, indirect impact on the increased resistance to pests damage plants provided growth regulators. Chemical disinfectants – Maxim and Vitaros – consistently reduced the infestation of fungi colonies in two years of investigations. But it should be noted that the growth regulators Appin Extra and Immunotsitofit also significantly reduced the number of agents of root rot, especially on small infected grain. Chemical disinfectants steadily reduced the infestation of grain only at grade Kinelsky Anniversary, other varieties disinfectants showed better performance only on heavily infected grain. The use of growth regulators in the pre-processing of spring wheat variety Kinelsky Anniversary, affected, of course, is positive on the phytosanitary state of the spring wheat crop, that resulting in higher yields.
