to yield reductions (Higley, 1992; Hunt et al., 1994; Haile et al., 1998). Hunt et al. (1994) concluded that removal Soybean [Glycine max (L.) Merr.] producers in many regions of of leaf area delayed the time to achieve a critical leaf the USA are confronted with significant yield losses because of crop damage from white-tailed deer (Odocoileus virginianus). Our objecarea index (LAI) of 3.5, li...

The belt uniform (BU) sowing pattern can improve the yield of winter wheat, but whether and how BU increase under different densities is unknown. field study was conducted in Guiyang (Guizhou province) during growing season 2017–2018, 2018–2019, 2019–2020. Four wheat cultivars were used experiments to investigate changes dry matter accumulation partition, components at maturity five (75, 150, 2...

In a vision-based automatic agricultural vehicle guidance system for row-crop applications, finding guidance information from crop row structure is the key in achieving accurate control of the vehicle. This paper describes a robust procedure to obtain a guidance directrix. The procedure includes row segmentation by K-means clustering algorithm, row detection by a moment algorithm, and guidance ...

In input intensive agriculture, weeds are major biotic constraints which likely to increase and become more complex. Overreliance on single weed management practice may further exaggerate severity also invite adverse effect, therefore, urgent technological intervention adopted eco-friendly integrated improve control sustaining the productivity in transplanted rice. The aim of study was compare ...

Existing plows do not provide high-quality tillage between rows of orchards and vineyards. The purpose the study is to develop justify parameters plow for cultivating soil gardens tractors class 0.9 kN. A design scheme a single-body smooth, rowless plowing garden aisles has been developed. proposed consists movable fixed frame, disc knife, screw body with hostage. research uses laws agricultura...

Abstract In the Republic of Uzbekistan, cotton cultivation is carried out on row spacings 60; 76 and 90 cm. The machine-tractor parks cotton-growing farms are equipped with agricultural machines designed for these inter-row they aggregated by tractors gauges them. Such a variety tractor creates problem mismatch between gauge spacing when moving from one to another, increases spare parts narrows...

R7 stage (one seed pod at mature color; 50% of leaves yellow) produced forage that was similar in quality to Tall forage soybean [Glycine max (L.) Merr.] cultivars in maturity alfalfa harvested at early bloom. When soybean was groups V, VI, and VII have been developed to supply forage. Our objective was to determine the effect of harvest date and row spacing grown as an intercrop with corn, the...

Plant spacing and nitrogen are the most important factors for increasing tuberose quality and quantity. In this study, field experiment carried out as factorial Randomized Completely Block Design (RCBD) in 3 replications. Different levels of nitrogen (0, 50, 100, 150, 200, 250 kg/ha) of ammonium nitrate was used. Second factor was different plant spaces (10, 15, 20 and 25 cm). Results showed th...

A field experiment was conducted during Kharif 2022 at Crop Research Farm, Department of Agronomy, SHUATS, Prayagraj (U.P). To study treatments consisting three levels Nitrogen such as, 80, 100 and 120 kg/ha with spacing as 75 x 10 cm2, 60 20 cm2 45 30 cm2. The soil experimental plot sandy loam in texture, nearly neutral reaction (pH 7.1), low organic carbon (0.28%), available N (225 kg/ha), P ...
