Effect of drip irrigation regimes and mineral fertilizer rates on watermelon yield in mulched fields

چکیده
Crop growth in arid and semiarid regions usually depends on irrigation, but inappropriate irrigation practice can result water stress. Water needs of watermelon are the highest during period strong formation vegetative generative organs. Thus, 85-90% moisture is required from seeds for seed germination. Before fruit, soil should be maintained at 70% total field capacity soil, time fruit ripening 60%. In this article, results experiments based development optimal regime fertilization rate cultivation plants mulched fields by drip method, differentiated (60...70...60%, 65...75...65%, 70...80...70%, 75...85...75% SAM (SAM - Soil available moisture)), rates (without fertilizer, N 100 P 80 K 40 , 120 50 140 60 kg/ha) have been written. Also, effect (N quality indicators amount dry matter, sugar, nitrates “C” has noted.

Effect of deficit irrigation on crop growth, yield and quality of onion in subsurface drip irrigation
Indiahas the largest area under onion (Allium cepa) crop but its average productivity (14.21 t ha-1) is considerably lower than the world’s average of 19.4 t ha-1. Besides low productivity, irrigation efficiencies are also very low i.e. 30-35% in India. Managing onion crop with less than adequate irrigation water availability is a challenge in several parts of the country. Options of i) deficit...
