The Effect of Different Irrigation Regimes on the Yield of Fodder Maize (Zea Mays)

A field study was carried out during 2013 season to investigate the effect of different irrigation intervals on fodder maize yield. Randomized complete block design (RCBD) was used, with three replicates. . Four irrigation regimes were executed T1=3 irrigations (1st 20 Day After Sowing (DAS), 2nd 35 DAS and 3rd 50 DAS), T2=3 irrigations (1st 20 DAS, 2nd 40 DAS and 3rd 60 DAS), T3=3 irrigations (1st 25 DAS, 2nd 40 DAS and 3rd 55 DAS), and T4=3 irrigations (1st 30 DAS, 2nd 45 DAS and 3rd 60 DAS). The results indicated that fodder maize yield varied significantly (P<0.05) under different irrigation regimes. The treatment T1 resulted the best, plant height (185.33 cm), number of green leaves (13.42), stem width (4.46 cm), and fodder yield (30580 kg.ha-1) While T2 resulted in the best Seed germination (86.91%). Finally, T1 irrigation regime was most effective to produce higher fodder yield in maize and the farmers may adopt this treatment to get high fodder production from maize.

Growth and yield of rice as affected by transplanting dates and seedlings per hill under high temperature of Dera Ismail Khan, Pakistan

Studies were initiated for two consecutive years to find out the effect of time of transplanting and seedlings hill(−1) on the productivity of rice in Dera Ismail Khan district of North West Frontier Province (NWFP), Pakistan. The experiment was laid out in a randomized complete block design with split plot arrangements. Main plots consisted of four transplanting dates viz. 20th and 27th of June and 4th and 11th of July while sub-plots contained 1, 2, 3 or 4 seedlings hill(−1). Among transplanting dates, June 20th planted crop gave highest paddy yield and net return with 1 seedling hill(−1). It explains that the use of more seedlings hill(−1) not only adds to cost but is also a mere wastage of natural resources. Based on research findings, we conclude that the use of 1 seedling hill(−1) is most appropriate for timely sowing otherwise 4 seedlings hill(−1) should be used to compensate for the yield gap in late transplanted rice
