Herbicides are mostly used to control weeds in irrigated areas, but neglected in rainfed areas due to uncertain and erratic rainfall patterns. A field experiment was conducted to investigate the efficacy of some herbicides for the control of broad leaved weeds in wheat crop during winter, 2014-15. Four herbicides, i.e., Ally Max (Metsulfuron methyl...

Hybrids of sunflower are more stable and highly self-fertile with a high yield performance and greater uniformity at maturity.Hybrid genotypes have been found to be superior in terms of seed yield to their parental lines. This research intended todevelop high-yielding cultivars to evaluate the comparative study for physiological, morphological and qualitative traits ofsunflower hybrids. Data of various growth, developmental, agronomic and yield traits were recorded to quantify the response. Analysis of variance showed that the hybrids were significant in all the traits, except for head and stem diameters.

. The maximum stemgirth was found for the SMH-1104 with the 25.43 cm, while the lowest value for the stem girth 19.7 cm was found for the SMH-1001. The maximum numbers of days to the flower completion was noted for the Hysun-33 with 93, while the minimum daysto flower completion were found for the SMH-1006, i.e., 83 for the flower completion. The results regarding chemicalattributes showed that the hybrid Hysun-33 was characterized by higher value of oil content (38.5%) and protein content(18.86%). While, on other hand NKS-278 showed maximum value for palmitic acid, oleic contents and linoleic acid. Furtherresearch permits the need to screen large number of hybrids-cultivars, their response to numerous growth and chemicalparameters to minimize the yield losses under dryland conditions.
... Moreover, the excess input of chemical fertilizers resulted in NO 3 leaching, volatilization of NH 3 , and NO x emission from agricultural fields and damaged both environment and human health [3,5,6,18,19]. Efforts have been devoted to reduce chemical fertilizers application in wheat production, and organic manure and biofertilizers amendments are considered to be feasible ways to realize this goal without decreasing grain yields [11,[20][21][22]. Application of organic manure can increase soil carbon, improve soil fertility, and obtain similar yield compared with inorganic fertilizer addition [18,23,24]. ...
The effects of long-term incorporation of organic manure and biofertilizers have been investigated on winter wheat in the North China Plain (NCP). The five-year field experiment (2013–2018) has illustrated the responses of grain yield and yield components. Seven fertilization approaches, included pig farm-yard-manure and biofertilizers amendments combined with five NPK% drop levels of chemical fertilizer ratio + organic fertilizer + biofertilizer (0, C+O+B) 25%, CL4; 50%, CL3; 75%, CL1; and 100%, CL0), without fertilizer as control (CK), in NCP during the years 2013–2018. Results showed that the grain yields of CL1 and CL2 were equivalent to CL0 in all growing seasons except 2014/2015. The grain yields of CL4 were 29.9% to 46.6% lower than that of CL0 during 2014/2015, 2016/2017, and 2017/2018. The valuable spike-number, grain number per-spike, and 1000-grain weight showed significant variations among different growing periods. Regression analysis of grain yield and yield components indicated that number grains per-spike showed significant increase in seed yield formation. The 1000-grain weight was the major parameter that influenced yield of moderate and low yielding periods, respectively. The results revealed that application of 30 m3 ha−1 pig farm-yard-manure and 20 kg ha−1 biofertilizers has reduced at least 50% of the NPK fertilization without dropping grain yields in the North China Plain.
