Promising Mungbean lines after transplanted Rice under three systems of land preparation
(Don Mariano Marcos Memorial State University - North La Union Campus, 2015-03) Corpuz, Ronnel L.
Tillage is a mechanical and manipulation action exerted on soil to modify soil conditions for nurturing crops. Therefore, a field study employing Split Plot design in RCBD factorial design was conducted comprising three systems of land preparation (zero tillage, minimum tillage, and conventional tillage) and six mungbean lines (EGM 05–731, EGM 05–738, EGM 05–744, LG Mg 6510–151, LG Mg 6506–127, and Kusapo). The study was conducted from November 23, 2014 to February 16, 2015 at Demonstration Farm, Bacnotan, La Union.Based on the findings of the study, planting mungbean in minimum tillage performed best in plant height, length of pod, survival rate, and seed yield, but comparable to zero tillage in terms of seed yield.LG Mg 6506–127 was the earliest to flower and mature, had the heaviest in weight of 100 seeds and the highest seed yield because of its bigger size.The interaction of mungbean lines, EGM 05–738 grown in zero tillage have significantly comparable to LG Mg 6506–127.
Foliar fertilzer supplement on the growth and yield of Rice 'NSIC Rc 278'
(Don Mariano Marcos Memorial State University - North La Union Campus, 2015-03) Calica, Ariel R.
Organic foliar fertilizers are considered as fast acting nutrient and environment friendly input. Thus the study was conducted at the Baroro Farm, Bacnotan, La Union from July to November 2014 to determine the growth and yield of rice ‘NSIC RC 278’ as affected by different organic foliar fertilizers, and to determine which among the organic foliar fertilizers can replace the 50% recommended rate. The experiment was conducted, following RCB Design with six treatments in three replications.
Application of 100% BSR (110-70-60 kg/ha) produced highest number of productive tillers (15.97) and grain yield (5130.17 kg/ha) but application with 50% BSR supplemented with either sargassum tea, vermitea and wokozim produced a comparable grain yield of 5020.66 kg, 4855.37 kg, and 4745.18 kg per hectare respectively and number of tillers of 15.27, 15.33, and 14.73, respectively in rice.
Performance of different Peanut lines under DMMMSU conditions
(Don Mariano Marcos Memorial State University - North La Union Campus, 2015-03) Bersalona, Winnie Ruth D.
Peanut variety that are high yielding and good quality, good characteristics, maturity and resistance to disease, drought and extreme temperatures are the primary considerations. The performance of the five (5) peanut lines (V1- LG Pn 11-C, V2- LG Pn 56, V3- LG Pn 06-3-1, V4- Pn 06-4-3, and V5- NSIC Pn 14) was evaluated to select a promising of peanut with high pod yielding ability and acceptable agronomic characteristic employing the Randomized Complete Block Design (RCBD) with 4 blocks at the Agricultural Technology Farm Center of the Don Mariano Marcos Memorial State University, North La Union Campus, Bacnotan, La Union from November 21, 2014 to February 21, 2015.
LG Pn 06-4-3 significantly produced the heaviest dried pod yield of 1895.75 kg/ha
comparable to LG Pn 56 (1584.31kgha), LG Pn 06-3-1 (16045.85kg/ha). LG Pn 06- 3- 1
flowered at 29.00 DAE and matured at 92.50 DAE.
There were no significant variations noted on plant height (46.34 cm to 50.55 cm),
survival rate (77.50 % to 95.56%), number of pods per plant (10.70 to 15.65), number of
seeds per pod (1.50 to 2.00), shelling percentage (62.25% to 75.50%), weight of 100 seeds (51.98 to 71.48) and weight of fresh pods (2083.53 g/plot or 1000.10 kg/ha to
2273.91g/plot or 1091.48 kg/ha).
Furthermore, the peanut lines have a “slight” pod beak, moderate to deep pod constriction and distinct pod reticulation, pinkish seed color, small to medium seeds size,
and oblong shapes with good quality seed.
Influence of planting dates for cluster Onion (Allium cepa l.) 'Batanes' in Tagudin Ilocos Sur
(Don Mariano Marcos Memorial State University - North La Union Campus, 2015-03) Barnachea, Claudine Maries L.
Cluster onion is a profitable cash crop planted after the rice cropping season in the municipality, with standing to this, planting dates influences the favourable growth and yield of the crop. Aside from this early harvest commends a higher market price ranging from Php.35.00 –Php.50.00 per kilogram. Hence this study was conducted at Brgy. San
Miguel, Tagudin, Ilocos Sur from October- January 2014.
The study was conducted with various planting dates as treatment which were: T1-October 1, T2-October 11, T3-October 21 and T4- October 31 following the Randomized Complete Block Design (RCBD) with three replications
The Batanes variety of cluster onion was used and planted following a distance of 20cm x 20cm. The transplants were mulched.
Result of the study revealed that planting date on October 31 registered the heaviest fresh weight of onion of 2.58 kg/plot or equivalent to 3,888.88 kg/ha with a net income of Php.139,940.63 having a return on investment (ROI) of 95.37%. Early planting in the locality from October 1-11 resulted to unfavourable growth and yield of cluster onion that greatly affected the yield production and net income as well.
Growth and yield of Glutinous Corn to different kinds of Organic fertilizer
(Don Mariano Marcos Memorial State University - North La Union Campus, 2015-03) Bangaoil, Charisse Marie B.
Using organic fertilizer is an effective way of producing chemical free food that sustain the health of the soil, ecosystem and people. Hence, this study was conducted to determine the best kinds of organic fertilizer on the growth and yield of glutinous corn. The Randomized Complete Block Design (RCBD) in three blocks was employed.
Result of the study revealed that application of organic fertilizer (50% RR + cattle manure, 50% RR + Coco coir dust and 50% RR +Vermicompost) significantly influenced the growth and yield of glutinouscorn. Applied with 50% RR +cattle manure obtained the highest yield but performed comparably with corn applied with 50% RR +coco coir dust, 50% RR + vermicompost, 100% RR in terms of plant. Corn that were not fertilized produced the lowest yield.ear size, and plant height.
