Abstract

 Water availability is a limiting factor to develop farming systems in the arid region, therefore more attention is given in the effort to increase water use true intercropping system. The research aim was to increase the productivity and land use efficiency. Research was conducted at field station of Agriculture Faculty, Haluoleo University. The experimental was arranged in completely randomized block design with two factors and three replications. The first factor was watering interval, i.e. once every 2, 4 and 6 days. Second factor is planting time of mungbean, i.e. 0, 7, 14, 21 and 28 days after planting (DAP) maize. The result showed that total yield of maize is 5.67 ton ha-1 in intercropping system occurred at delayed planting of mungbean, i.e. at 14 DAP maize, and watering interval every 4 days. Our result showed that intercropping system could improve yield up to 39.68% compared to monoculture planting system of maize and mungbean. Leaf area index, long ear and number of grain per ear of maize have correlation  with yield. Number of pod per hill of mungbean has correlation to weight of 1,000 grain and dry pod yield. Percentage of pod emptiness has negative correlation to  weight of 1,000 grain and dry pods yield.    Keywords: intercropping, LER,  maize, mungbean,  water availability

Abstract

Mungbean is traditionally intercropped with maize by small-scale farmers which do widely in the tropics, including Southeast Sulawesi.  This study aims  to  assess the radiation use efficiency (RUE) and soil water content (SWC) in maize intercropped with mungbean. The research was arranged on Split-Plot Design of  two factors, i.e. dose of “komba-komba” compost as the main plot consists on 5 t ha-1 and 10 t ha-1 and planting time of mungbean as a subplot, consists on planting mungbean with maize at the same time, delayed planting of mungbean 7 and 14 days after planting (DAP) of maize.  The results shown  that the highest RUE of maize 2.69 g MJ-1 and 3.15 g MJ-1 obtained on komba-komba compost dose 10  t ha-1 and planting mungbean 7 DAP of maize, while highest RUE of mungbean  0.31  g MJ-1  and  0.60  g MJ-1  obtained  on  komba-komba compost dose 10 t ha-1 and planting mungbean and maize at the same time, respectively.  The  soil  temperature  has  negatively correlated with  (SWC)  that  at  the  komba-komba compost with rxy = - 0.7422 and at the time planting of mungbean in intercropping with maize with rxy = - 0.7922.

Abstract

Utilization of climatic information and physical characteristics of the soil to determine the soil water balance in agriculture is a very important factor because it relates to the planning model of activity to be undertaken. This is important because the output is known a periods of surplus and deficit water of the regions. Periods of surplus and deficit is implications for the length of growth period available to facilitate the planning of agricultural models that will be developed. The planning agricultural model is still oriented to the needs of farmers and the willingness of the government, not based on the climatic information and physical characteristics of the soil. Keywords : climatic information, soil characteristics, water balance.

Abstract

The purpose of this research is to investigate the productivity of land by N,P,K fertilizer and time of planting peanuts in intercropping systems with maize. This research was conducted applying experimental garden at Agriculture Faculty of Halu Oleo University, Kendari. The research was conducted in the dry season, from August to November 2015. The research was arranged meant by split plot design with two replications. The main plot is NPK fertilizer dose (S) consisted of three levels namely 56-36-25 kg ha-1 (S1), 90-54-25 kg ha-1 (S2) , 124-72-50 kg ha-1 (S3). The subplots was planting time of peanuts with maize intercropping (W) consisted of three levels, namely planting time of peanuts 10 days before planting (DBP) maize (W1), planting peanuts with maize simultaneously (W0), and planting peanuts 10 days after planting (DAP) maize (W2). There are nine treatment combinations of two factors mentioned. Each combination treatment was repeated three times, coupled with each of the three experimental plots for monoculture cropping systems of peanuts and maize. The total number of units was 45 units experimental. Data experiments were analyzed by using analysis of variance followed by Duncan's Multiple Range Test. The results showed that the treatment time 10 DBP planting peanuts with maize to increase productivity, reduce competition index and efficient of the use fertilizer. Provision of fertilizer NPK 124-72-50 kg ha-1 dose can increase growth and yield of maize and peanuts
