Vegetables have a relatively high nitrogen requirement and at times growers apply too much fertilizer-N that contributes to ground and surface water pollution. Fertilization can be made more efficient by plant analysis. Plant tissue (petiole) nitrate testing is a way of monitoring the nitrogen condition of the crop during the growing season. This is an especially useful method as the petiole is...

Oil palm propagation techniques are juvenile pot plants derived from germinated seeds and tissue culture, because it doesn’t produce sucker. In the nursery stage, monitoring the conditions of irrigation and nutrition are important to ensure phenotypic quality. During the nursery stage, optimal fertilization in development of more vigorous and productive plants. This research was carried out to ...

An experiment on cauliflower was carried out at Water Technology Centre, Rajendranagar, Hyderabad, Telangana during rabi 2019-2020. Experiment laid in split plot design with nine treatments consists of three drip irrigation levels (0.6, 0.8 and 1.0 Epan) as main plots NK fertigation (Control, 40:50 80:100 kg N K2O ha-1) subplots. The results revealed that EPan recorded significantly higher curd...

Protected cultivation is a resource-efficient method of crop production, however, at the same time, it resource intensive. An optimum rate and time fertilizer application required in order to maximize yield vis-à-vis use efficiency. However, these aspects are scarcely studied for tomato under low- medium-tech greenhouses Indian humid sub-tropics. In this regard, two-year study was conducted ass...

An experiment entitled “Growth, yield and water use efficiency of sweet sorghum [Sorghum bicolor (L.) Moench] affected by drip irrigation nitrogen levels through fertigation” was carried out on clayey slightly alkaline soil during rabi season 2019-20 2020-21 at the Instructional Farm, Department Agronomy, College Agriculture, Junagadh Agricultural University, Junagadh. The laid in split plot de...

Greenhouse is a kind of agricultural building structure with glass or plastic roof, where the vegetables or flowers can grow well year round by controlling the inside climatic environment. Fig. 1 shows commercial multispan greenhouses in China. The closed environment of a greenhouse has its own unique requirements, compared with outdoor production. Pests and diseases, and extremes of heat and h...
