Accurate pre-harvest estimation of avocado (Persea americana cv. Haas) yield offers a range of benefits to industry and growers. Currently there is no commercial yield monitor available for avocado tree crops and the manual count method used for yield forecasting can be highly inaccurate. Remote sensing using satellite imagery offers a potential means to achieve accurate pre-harvest yield forec...

in order to study the effect of irrigation and nitrogen fertilizer levels on yield of basil, an experiment was conducted as split plot based on randomized complete block design with three replications in birjand (moud region) in 2010. main plot factor was two irrigation levels (7 and 14 days interval) and nitrogen fertilizer (as urea) was considered as sub plot factor in four levels (0, 50, 100...

to reduce peat while increasing the water holding capacity (whc) of casing soil in button mushroom production an experiment was conducted in 2006 with three hydrogel treatments of: t0= casing soil with no hydrogel, as control, t1= casing soil + 10% hydrogel (v/v), and t2= casing soil + 20% hydrogel (v/v) with three replicates in a completely randomized design. results indicated that treatment 1...

Crop show morphological and physiological responses to microbial, physical or chemical factors which are known as elicitors. Chitosan is a natural biopolymer modified from chitin, which is the main structural component of squid pens, cell walls of some fungi and crab shells. Water stress is one of the most important abiotic stresses that affects plant physiological and morphological traits. In ...

BACKGROUND: Polyacrylamide is the main synthetic polymer used, and it absorbs water through the formation of hydrogen bonds. Super Absorbent Polymer (SAP) can absorb water up to 200-400 times its weight and increase its size by up to 100 times. OBJECTIVES: Evaluate effect of different irrigation regime and super absorbent polymer on agrop...

Switchgrass (Panicum virgatum L.), a US Department of Energy model species, is widely considered for US biomass energy production. While previous studies have demonstrated the effect of climate and management factors on biomass yield and chemical characteristics of switchgrass monocultures, information is lacking on the yield of switchgrass grown in combination with other species for biomass en...

Kiwifruit requires a high quantity of nutrients that must be supplied through fertilization to obtain an optimum yield on a sustainable basis. This research was conducted to evaluate different fertilization methods including broadcast application (as control), deep placement of the fertilizer and fertigation, alone or in combination with foliar application and their effects on the yield, leaf m...
