Varying moisture deficit on the growth and yield of Tomato (Var. diamante) under upside down and upright planting conditions
(Don Mariano Marcos Memorial State University - North La Union Campus, 2010-03) Cariño, Citadel D.
The study was conducted in a greenhouse establish at the west side of the Agricultural Engineering building from December 21, 2009 to February 14, 2010 to determine the significant effects of frequency of irrigation on the growth and yield as related to method of planting and water to irrigate.
Two factors involved in the study include available moisture deficit and method of planting. The treatment combinations/interactions were replicated three times and laid out following the Randomized Complete Block Design (RCBD). The following parameters were measured namely: weekly length increment, yield of plants, mean diameter of fruits, number of fruits, time of fruiting, length of roots, rate of survival and volume of water applied. Plants were irrigated at certain allowable moisture deficit, 35% - 40% of allowable moisture deficit, 40% - 45% of allowable moisture deficit, 55% - 60% of allowable moisture deficit, and the other one is irrigated with allowable moisture deficit of 65% - 70%.
The method of planting followed the upright and upside down position. Analysis of Variance experiment was used to determine whether there was a significant difference among the treatments. The Duncan's Multiple Replication Test (DMRT) was used for further test of significance.
Level of allowable moisture deficit revealed significant effect on the length of plant, weight, number and diameter of fruits, time of fruiting, rate of survival as well as the length of roots.
Method of planting showed significant effect on the length of plants and length of roots but no significant effect on the weight, number and diameter of fruits, time of fruiting and rate of survival.
Treatment combinations indicated significant effect on the length of plants, weight, number, and diameter of fruits, time of fruiting but no significant effect on the rate of survival and length of the roots.
The total amount of water applied was highest in Treatment A and lowest in Treatment B at 24.996437 liters and 13.76184 liters, respectively.
Performance evaluation of the Grass cutter modified into a Rice Harvester
(Don Mariano Marcos Memorial State University - North La Union Campus, 2010-03) Biscarra, Lenie Rea E.; Lazaga, Aldwin P.
The study was conducted to modify the grass cutter into a rice cutter harvester to evaluate its field performance in terms of its actual field capacity, theoretical field capacity, field efficiency and fuel consumption and its adaptability in dry and wet field condition.
Locally, grass cutters spread out and most farmers used it only in cleaning the field, trimming and cutting grasses. Hence, modification of the grass cutter into a rice harvester was one way in meeting the needs of farmers that is to save on labor cost, increase productivity, and lessen the difficulty in rice harvesting and has a portable rice harvesting machine.
The construction of the attachment was done at the Department of Agricultural Engineering, DMMMSU NLUC, Bacnotan, La Union and was welded at the Maala's Welding Shop at Say-oan, Bacnotan, La Union. The attachment was made of steel shaft and steel plate welded together and a galvanized iron sheet secured by rivet.
The testing of the machine was done at the farm located at Brgy. Barrio-An, Tagudin, Ilocos Sur. It was tested on dry and wet field to determine its adaptability.
Based on the result of the study, the machine has an actual field capacity of 6.96 m²/mins. (0.33ha/day) in the dry field condition and 6.63 m²/mins. (0.32 ha/day) in wet field condition and it has a fuel consumption of 0.57 li/hr in dry field and 0.62 in wet field.
The total cost of the attachment was P 723.10 including labor cost. The initial cost of the attachment was P 723.10. The rice harvester has initial cost of P13, 523.10 with a machine income of P 42,429.92/ha-yr in dry field and P 36,775.58/ha-yr in wet field.
Comparative evaluation of different controlled Irrigation methods as applied to Rice production
(Don Mariano Marcos Memorial State University - North La Union Campus, 2010-03) Aloot, Sahleemar B.; Rafael, Mark Noel B.; Villanueva, Cathelyn D.
This study was carried out to determine the best irrigation method for rice production using the different controlled irrigation systems namely: drip irrigation, furrow irrigation, and flooding irrigation in terms of growth, yield and water application efficiency as well as to perform the cost and return analysis. The study was conducted at the Don Mariano Marcos Memorial State University, Baroro Farm, Bacnotan La Union from October 2009 to January 2010.
Rice variety 152 (tubigan) was being used in the study and was raised for 101 days for each treatment.
Results revealed that the height of the plant were not significant, the flooding irrigation method has the highest applied water thus produces highest yield. With drip irrigation method having the highest cost of expenses gives the second highest yield, while furrow irrigation method gives the lowest yield.
Storability of powdered Malunggay (Moringa oleifera lam.) leaves using different packaging materials
(Don Mariano Marcos Memorial State University - North La Union Campus, 2009-03) Rodriguez, Fatima S.
This study was conducted to determine the effect of the different packaging materials for powdered malunggay leaves after 18 weeks of storage at the Crop Processing Laboratory Room of the Agricultural Engineering from August 27, 2008 to January 27, 2009. Specifically, this study aimed to determine the following: (1) the quality and quantity of powdered malunggay leaves using different packaging materials in terms of color and weight, respectively; (2) the best packaging material for powdered malunggay leaves; (3) the Vitamin C content of powdered malunggay after storage; (4) the relationship between temperature and weight after storage; and (5) the relationship between relative humidity and weight after storage..
Four treatments, replicated three times with three samples each, were used with the weight of the samples corrected to compensate for the non-uniformity of the samples obtained. The samples were randomly distributed following the Completely Randomized Design (CRD), with the following parameters: weight before and after storage, color before and after storage and Vitamin C content before and after storage.
Analysis of Variance, Single-factor was used to determine whether there was a significant difference among the treatments. Polynomial model and simple linear-regression analysis were used to determine the relationship between the weight of the powdered malunggay and climatic factors (temperature and relative humidity).
Results showed that the parameters considered in the study (weight before and after storage; color before and after storage) were not significantly different among the treatments; however, Vitamin C content of the samples after storage significantly differed from the Vitamin C content of the sample before storage.
Low temperature and high relative humidity significantly increased the weight of the samples.
Evaluation of mist and traditional irrigated Forestry seedlings
(Don Mariano Marcos Memorial State University - North La Union Campus, 2009-03) Milan, Russelle D.
This study was conducted to evaluate the survival and growth of mist and traditionally irrigated forestry seedlings such as mahogany, neem, and narra in terms of diameter, height, number of leaves and length of roots produced. The study was conducted at the Agroforestry Nursery, DMMMSU-NLUC, Bacnotan, La Union from November 12, 2008 to January 14, 2009.The treatments were as follows:
T₁ - Traditional irrigation
T₂ - Mist irrigation
T-test was used in determining the existence of difference in the effect of mist and traditional irrigation methods on the growth of mahogany, neem and narra seedlings.
The utilization of mist and traditional irrigation method was evaluated. The results indicated that there were no significant difference in the effect of the two methods of irrigation on the growth of mahogany, neem, and narra in terms of stem diameter, height, number of leaves and length of roots produced.Do you have more excerpts to transcribe, or would you like to compare these findings with the previous study on mahogany soil media?Ask about
