Seaweed (Sargassum sp.) liquid fertilizer with Vermicast tea on the growth and yield of yellow corn (Bt rr) intercropped with red beans
(Don Mariano Marcos Memorial State University - North La Union Campus, 2014-03) Natan, Cristilyn P.
The existing farming system uses synthetic chemicals and pesticides which destroys the ecosystem and biodiversity. Therefore, there is an urgent need to explore alternatives of synthetic chemicals currently in used in agriculture. Hence, this study on seaweed (sargassum sp.) liquid fertilizer with vermicast tea on the growth and yield of yellow corn (Bt rr) intercropped with common red beans was conducted from October 2, 2013 to February 18, 2014 at the Citrus Project of DMMMSU-NLUC, Bacnotan, La Union.
Results revealed that the reduction of BSR to 1 4⁄ of the recommended rate but with the addition of 3 liters VCT + 3 liters of SLF significantly out yielded the other corn plants subjected to other treatments except those applied with 1/4 BSR + 3 liters VCT + 3 liters of SLF per linear meter which were found comparable. Further, chemical fertilizer can be substituted with pure VCT plus SLF.
Growth and yield of yellow corn 'DK9132 YG2RRC2' as affected by rates of Vermicompost with supplement
(Don Mariano Marcos Memorial State University - North La Union Campus, 2014-03) Marzo, Pamela H.
The demand of safe and healthy feeds and a healthy environment calls for
organic production technologies especially in reducing use of chemical fertilizer. Hence,
this study was conducted to determine the effects of rates of vermicompost with
supplement on the growth and yield of yellow corn and it was conducted at the
Experimental Field of the DMMMSU-NLUC, Sapilang, Bacnotan, La Union from
October 25, 2013 to February 08, 2014 following the Randomized Complete Block
Design (RCBD) in three blocks.
Plants applied with 4kg vermicompost per linear meter or applied with 50%
BSR + 2kg vermicompost supplemented with either Bio-N inoculation or Crop Giant
spray performed comparably with those applied of BSR (150-30-0kg/ha) in terms of
growth but performed better in terms of yield.
Fish amino acid (FAA) on the growth and yield of yellow corn (Bt rr) intercropped with mungbean (var. Mg12)
(Don Mariano Marcos Memorial State University - North La Union Campus, 2014-03) Labador, Rohanna Joy A.
Due to the harmful effects of chemical fertilizers to the environment and to the health of the populace, the need to explore alternatives which are locally available and abundant. Hence, this study on FAA for yellow corn intercropped with mungbean was conducted from October 2, 2013 to February 18, 2014 at the citrus project of DMMMSUNLUC.
Results revealed that application of four liters FAA per linear meter of yellow corn intercropped with mungbean is comparable to those applied with commercial fertilizer (BSR) in terms of growth and yield performance.
Mungbean as intercrop when applied with ¼ BSR + 3 litters FAA per linear meter performed comparably with those applied with 100% chemical fertilizer.
Rates of vermicompost application on Mungbean (Vigna radiata l.)
(Don Mariano Marcos Memorial State University - North La Union Campus, 2014-03) Gojar, Jeric B.
Vermicompost, a product or process of composting using various worms is very effective organic fertilizer usually used in crops. This was conducted to determine the effect of different rates of vermicompost on mungbean ( T0 – No Application, T1– RR kg N/ha), T2 – 4kg vermicompost + RR, T3 – 8kg vermicompost + RR, T4 – 12kg vermicompost + RR) employing RCBD in 3 blocks. This study was conducted at the Experimental Farm of DMMMSU-NLUC from November 2013 – January 2014.
Plants applied with 12kg vermicompost produced more number of seeds per pod. However, no significant variations were recorded in terms of days to emergence, flowering, maturity, number of pods per plant, length of pods, plant height, reaction to pest and diseases, weight of 100 seeds and seed yield.
Field trial of Soybean entries under Lacong, San Gabriel, La Union condition
(Don Mariano Marcos Memorial State University - North La Union Campus, 2014-03) Elias, Kevin E.
In order to solve the increasing demand and limiting supply of soybean in the country, the performance of seven soybean entries (Lg Sy 02-34-2, Lg Sy 02-34-10, Lg Sy 02-34-14, Lg Sy 02-34-27, Lg Sy 9956, Lg Sy 63 and Nsic Sy 9) were evaluated to identify the location specific and high yielding soybean entries under lacong, san gabriel, la union condition employing rcbd in four blocks from November 24, 2013 to February 19, 2014.
Lg Sy 02-34-2 significantly produced the longest pod (4.12 cm). LG Sy 63 had significantly developed the most number of pods per plant (35.28) and seeds per pod (2.77). LG Sy 02-34-14 and Lg Sy 63 had significantly exhibited the tallest plants. LG Sy 02-34-2 flowered and matured the earliest but produced the least number of pods per plant and number of seeds per pod. LG Sy 02-34-2, Lg Sy 02-34-27, Lg Sy 9956 and to NSIC Sy 9 (NC) are highly resistant to powdery mildew.
